Abstract
S-Adenosyl-l-methionine (SAM) is an important cosubstrate in various biochemical processes, including selective methyl transfer reactions. Simple methods for the (re)generation of SAM analogs could expand the chemistry accessible with SAM-dependent transferases and go beyond methylation reactions. Here we present an efficient enzyme engineering strategy to synthesize different SAM analogs from "off-the-shelf" iodoalkanes through enzymatic alkylation of S-adenosyl-l-homocysteine (SAH). This was achieved by mutating multiple hydrophobic and structurally dynamic amino acids simultaneously. Combinatorial mutagenesis was guided by the natural amino acid diversity and generated a highly functional mutant library. This approach increased the speed as well as the scale of enzyme engineering by providing a panel of optimized enzymes with orders of magnitude higher activities for multiple substrates in just one round of enzyme engineering. The optimized enzymes exhibit catalytic efficiencies up to 31 M-1 s-1, convert various iodoalkanes, including substrates bearing cyclopropyl or aromatic moieties, and catalyze S-alkylation of SAH with very high stereoselectivities (>99 % de). We further report a high throughput chromatographic screening system for reliable and rapid SAM analog analysis. We believe that the methods and enzymes described herein will further advance the field of selective biocatalytic alkylation chemistry by enabling SAM analog regeneration with "off-the-shelf" reagents.

Abstract
Most superconductors have an isotropic, single component order parameter and are well described by the standard (BCS) theory for superconductivity. Unconventional, multiple-component superconductors are exceptionally rare and are much less understood. Here, we combine scanning tunneling microscopy and angle-resolved macroscopic transport for studying the candidate chiral superconductor, 4Hb-TaS2. We reveal quasi-periodic one-dimensional modulations in the tunneling conductance accompanied by two-fold symmetric superconducting critical field. The strong modulation of the in-plane critical field, Hc2, points to a nematic, unconventional order parameter. However, the imaged vortex core is isotropic at low temperatures. We suggest a model that reconciles this apparent discrepancy and takes into account previously observed spontaneous time-reversal symmetry breaking at low temperatures. The model describes a competition between a dominating chiral superconducting order parameter and a nematic one. The latter emerges close to the normal phase. Our results strongly support the existence of two-component superconductivity in 4Hb-TaS2 and can provide valuable insights into other systems with coexistent charge order and superconductivity.

Abstract
OBJECTIVE To evaluate the reasons for COVID-19 vaccine hesitancy during pregnancy. DESIGN We used regular expressions to identify publicly available social media posts from pregnant people expressing at least one reason for their decision not to accept COVID-19 vaccine. SETTING Two social media platforms - WhatToExpect and Twitter. SAMPLE A total of 945 pregnant people in WhatToExpect (1017 posts) and 345 pregnant people in Twitter (435 tweets). METHODS Two annotators manually coded posts according to the Scientific Advisory Group for Emergencies (SAGE) working group's 3Cs vaccine hesitancy model (confidence, complacency and convenience barriers). Within each 3Cs we created subthemes that emerged from the data. MAIN OUTCOME MEASURES Subthemes were derived according to the people's posting own words. RESULTS Safety concerns were most common and largely linked to the perceived speed at which the vaccine was created and the lack of data about its safety in pregnancy. This led to a preference to wait until after the baby was born or to take other precautions instead. Complacency surrounded a belief that they are young and healthy or already had COVID-19. Misinformation led to false safety and efficacy allegations, or even conspiracy theories, and fed into creating confidence and complacency barriers. Convenience barriers (such as availability) were uncommon. CONCLUSION The information in this study can be used to highlight the questions, fears and hesitations pregnant people have about the COVID-19 vaccine. Highlighting these hesitations can help public health campaigns and improve communication between healthcare professionals and patients.

Abstract
Methods for regioselective N-methylation and -alkylation of unsaturated heterocycles with "off the shelf" reagents are highly sought-after. This reaction could drastically simplify synthesis of privileged bioactive molecules. Here we report engineered and natural methyltransferases for challenging N-(m)ethylation of heterocycles, including benzimidazoles, benzotriazoles, imidazoles and indazoles. The reactions are performed through a cyclic enzyme cascade that consists of two methyltransferases using only iodoalkanes or methyl tosylate as simple reagents. This method enables the selective synthesis of important molecules that are otherwise difficult to access, proceeds with high regioselectivity (r.r. up to >99 %), yield (up to 99 %), on a preparative scale, and with nearly equimolar concentrations of simple starting materials.

Abstract
Background The COVID-19 containment measures, implemented to curb the pandemic, impacted health of children and adolescents by numerous pathways. We present the impact on health care utilization and provision. Methods A systematic review on secondary health impact is ongoing (PubMed, PsychInfo, Embase). Literature is screened (title, abstract, full-text) by 2 researchers, and data of interest extracted systematically.. Inclusion criteria are age (0 - 25 yrs.), exposure: containment measures, outcome: secondary health outcome, and European data origin. Results Jan. 2020 - Aug. 2021 10112 studies were identified, 337 were included. n = 60 were on health care utilization and provision. Utilization studies relied on objective hospital or registry data, care provision studies more often on survey data (professionals, parents). Data yields a large but varying decrease in emergency department visits during the lockdown: Italy ∼75%, Spain ∼65%, France ∼60%, and Germany ∼64%, and a substantial change in case mix and severity compared to comparable pre-COVID. Specialized and primary pediatric practices report that elective interventions were postponed, state of the art diagnostics withheld, and rehabilitation services disrupted. Vaccinations in infants, children, and adolescents dropped during the lockdown inversely proportional to children's age. Studies repeatedly suggest patients’ health services avoidance out of fear of infection and stay-at-home rules.Results on catch-up utilization and provision to follow (ongoing study). Conclusions COVID-19 measures exerted a measurable impact on health utilization and provision in children and adolescents. The utilization was comparatively lower and service provision disrupted across Europe. So far little can be said about a potential recovery in terms of catch-up of visits, diagnostics, or treatments. Analyses of the long-term health impact of the observed effects is recommended and can serve to improve future pandemic preparedness. Key messages • COVID-19 confinement measures had measurable secondary health impact on children and adolescents. • Data on catch-up healthcare is important to establish long term impact and learnings.

Abstract
Background Congenital Disorders of Glycosylation (CDG) are a large group of inborn errors of metabolism with more than 140 different CDG types reported to date (1). The first characterized, PMM2-CDG, with an autosomal recessive transmission, is also the most frequent. The PMM2 gene encodes a phosphomannomutase. Here, a novel genetic variation causing PMM2-CDG is reported. Case presentation We report the case of a French child, from healthy and unrelated parents, presenting congenital ataxia with hypotonia, hyperlaxity, inverted nipples, as well as altered coagulation parameters and liver function. Transferrin isoelectrofocusing revealed a typical type I CDG profile. Direct Sanger sequencing and quantitative PCR of PMM2 revealed a unique and novel genotype. On one allele, the patient was heterozygote with a known missense variant NM_000303.3(PMM2):c.323C > T, p.Ala108Val in exon 4. On the second allele, whole genome sequencing (WGS) indicated the presence of a novel heterozygous 70 kb deletion. Conclusion We report in the present paper the largest known heterozygous deletion of a PMM2 gene. The observation reveals the impact of a precise diagnostic on genetic counselling: by using WGS, an erroneous conclusion of homozygosity in the case of a relatively rare variant could be avoided, and an index patient with healthy and unrelated parents correctly identified.

Abstract
BackgroundAlthough the risk for severe COVID-19 progression in children is low, this may be aggravated by the underlying disease and/or immunosuppressive drugs.ObjectivesWe analyzed clinical data of COVID-19 cases among paediatric patients with rheumatic diseases reported to the BIKER registry.MethodsThe main task of the German BIKER (Biologics in Pediatric Rheumatology) registry is to monitor the safety of biologics therapies in JIA. After the onset of the COVID-19 pandemic, the survey was expanded with a standardized form to proactively interview all participating centers about the occurrence, presentation, and outcome of SARS-CoV-2- infections in children with rheumatic diseases. Interviews were conducted with 68 centers initially weekly and later biweekly.ResultsA total of 68 centres participated in the survey. Clinical data from 194 COVID-19 cases reported to the BIKER registry from 41 German and 1 Austrian pediatric rheumatology institutions between February 2020 and December 2021 were analyzed. Juvenile idiopathic arthritis (JIA, n=144) was the most common diagnosis followed by genetic autoinflammation (n=18; i.e. FMF, TRAPS, CAPS, HIDS, DADA2), systemic autoimmune diseases (n=11; i.e. SLE, dermatomyositis, vasculitis) and 16 with other rheumatic diseases (i.e. CRMO, Uveitis). 5 patients with no rheumatic disease were excluded. 104 (54%) patients were receiving conventional DMARDs, 81 (43%) received biologics, mainly TNF inhibitors (n=66 (35%)).Of the 189 rheumatic patients with SARS-CoV2 infection, 123 (63%) were female. The mean age was 12.4+/-4.4 years in females and 13.2+/-4.1 in males. The duration of SARS-Co2 infection associated symptoms was 13.8+/-15.3 days (max. 113 days), in 35 (43%) patients they lasted for > 12 days. 46 (24%) were asymptomatic. Patients with autoinflammation and systemic autoimmunopathies reported more symptoms such as fever, head and throat ache. 4 patients only complained about dyspnea.Only 3 patients were hospitalized and received Oxygen-supplementation. The only patients admitted to ICU, received ventilation but succumbed. This 3½-year-old patient, initially diagnosed with systemic JIA, developed fatal disease with intracranial edema and respiratory failure, as well as typical pulmonary texture changes. Prior to her SARS-CoV-2 infection, the patient was treated with MTX and low-dose steroids. Genetic testing revealed a so far unrecognized congenital immunodeficiency.In the total JIA cohort, treatment with corticosteroids, conventional DMARDs, biologics or combinations did not influence the number of reported symptoms or the favorable outcome of the cohort. However, the duration of symptoms was lower in the TNF-treated cohort (10.4+/-6.4 days vs. 15.7 +/- 19.7 days). In the cohort with autoinflammation, fever was observed in 11 (61%). Those 6 who received IL-1-inhibitors did not show a different outcome than those 12 who did not. No case of PIMS/MISC in children with rheumatic diseases was reported.ConclusionExcept for one patient with congenital immunodeficiency who died from her COVID-19 infection, no case of severe COVID-19 was reported in our cohort. At the time of infection, over 80% of patients in our cohort had been treated with conventional DMARDs and/or biologics. This did not appear to have a negative impact on the severity or outcome of SARS-CoV2 infection. Interestingly, no case of PIMS/MISC was observed.Disclosure of InterestsGerd Horneff Speakers bureau: Novartis, Pfizer, Janssen, Grant/research support from: Pfizer, Novartis, Roche, MSD, Frank Dressler Speakers bureau: Pfizer, Novartis, Abbvie, Paid instructor for: Advisory boards Novartis, Mylan, Daniel Windschall Speakers bureau: Pfizer, Novartis, Abbvie, MEDAC, Canon, Grant/research support from: Novartis, Pfizer, Sonja Mrusek: None declared, Toni Hospach: None declared, Alexander Kühn: None declared, Maria Haller: None declared, Philipp von Bismarck: None declared, Wolfgang Emminger: None declared, Peggy Ruehmer: None declared, Markus Hufnagel: None declared, Ariane Klein Speakers bureau: Novartis

Abstract
BackgroundTocilizumab (TCZ) has been approved for treatment of juvenile idiopathic arthritis (JIA) for 10 years.ObjectivesEvaluation of 12-month efficacy and safety of TCZ compared to TNF inhibitors (TNFi).MethodsBIKER WA 29358 is a 5-year multi-centre prospective, observational cohort study including polyarticular JIA patients in Germany starting treatment between 2015 and 2020 with TCZ and matched 1:1 by date of treatment start and region to patients starting an approved TNFi. Clinical disease activity (JADAS10), JADAS MDA (≦3.8)/remission (≦1.0), safety and drug adherence at 12 months were assessed and compared between cohorts.ResultsThe analysis included 342 participants with 12-month treatment data (TCZ n=171; TNFi n=171). TCZ was used as 2nd line biologic in the majority of patients (84%) while TNFi were mostly 1st line biologics (86%). Patients starting TCZ had a longer disease duration. Efficacy was demonstrated by a marked decrease in JADAS10 in both cohorts (TCZ vs. TNFi at baseline: 15.0+/-6.7 vs. 14.6+/-6.3; at month 12: 3.8+/-5.1 vs. 3.4+/-4.5). Proportions of patients in TCZ/TNFi cohorts achieving JADAS remission at 12 months were 48%/41% in 1st line biologic users and 32%/33% in 2nd line biologic users. JADAS MDA was achieved in 64%/69% in 1st line and 52%/58% in 2nd line users of TCZ/TNFi.After 12 months of treatment JADAS10 (mean +/SD) was higher in the 2nd line TNFi cohort compared to the 1st line (4.5+/-5.6 vs. 3.2+/-4.3), similar to patients receiving 2nd or 1st line TCZ (4.0+/-5.2 vs. 2.9+/-4.4). Patients receiving TCZ or TNFi as first biologic reached JADAS10 remission and MDA numerically more frequently but not statistically significant compared to 2nd line users.Safety was assessed based on adverse event (AE) reporting. 57 (33%) patients in the TCZ cohort and 43 (25%) patients in the TNFi cohort reported AE. The AE rate was significantly higher in the TCZ cohort (69 vs. 44.8/100 patient years, RR 1.5 [95%CI 1.1-2.0], p=0.006, Wald-test). There were 6 serious AE in the TCZ and 3 in the TNFi cohort. Injection site reactions were more common in the TNFi cohort (9 vs. 1, p=0.043). No further differences were identified to date. There was no death and no opportunistic infection.In the TCZ cohort, 32 patients discontinued treatment, 27 due to lack of efficacy, while in the TNFi cohort only 6 patients discontinued treatment. Treatment discontinuation was more frequent among the 2nd biologic users (n=29; 17.4%) than in first line users (n= 9; 5.1%).ConclusionIn this first interim analysis, treatment targets were reached with similar frequency after 12 months of treatment with TCZ or TNFi. TCZ was used predominantly as 2nd line biologic. Higher rates of remission /MDA were observed in 1st line compared to 2nd line biologic users. Although more AE were reported in the TCZ cohort, the occurrence of serious AE and infections was comparable in both cohorts. No new safety signals were identified.

Abstract
BackgroundThe ProKind Commission of the Society for Paediatric and Adolescent Rheumatology (GKJR) has developed evidence- and consensus-based protocols for the diagnosis and therapy of children and adolescents with defined rheumatic diseases (e.g., [1]). In the ProKind-Rheuma project, it is now investigated whether the protocols are followed in everyday clinical practice and what the treatment-associated outcomes are.ObjectivesTo investigate the mode of treatment and treatment response in patients with polyarticular juvenile idiopathic arthritis (pJIA).MethodsProKind-Rheuma is a multicenter prospective non-interventional observational study. Patients with pJIA enrolled until 17/1/2022 were included into this analysis. Treatments and outcomes up to the 3-month follow-up visit (3FU) were analyzed. Disease states were categorized based on the 2021 cJADAS10 cutoffs [2].ResultsTo date, 18 pediatric rheumatology facilities have participated in ProKind-Rheuma. Data from 203 patients with JIA are available. Of those, 44% have oligoarthritis, 36% polyarthritis, 9% systemic JIA, 6% enthesitis-related arthritis and 3% psoriatic arthritis.In total, 76 patients were diagnosed with pJIA, 38 with already completed 3FU:For 23 patients with pJIA and completed 3FU, we were able to analyze the protocol-defined [1] treatment goal of at least “minimal improvement”. In total, 18 (78%) achieved minimal improvement, 5 (22%) missed it. For 4 of those 5 patients, the underlying MTX therapy was escalated to a bDMARD (3 changed to MTX+bDMARD-combi, 1 to bDMARD-mono). In 3 other patients, therapy was also escalated to an MTX+bDMARD-combi.Between baseline and 3FU, 72% achieved cJADAS10-disease state improvement (Table 1) by at least one category (range 1 - 2), 0% decreased.Table 1.*based on non-missing valuesAt Baseline allAt Baseline with 3FUAt 3FUTotal7638Female, n (%)58 (76)30 (79)Age (years), Mdn (IQR)9 (3-12)7 (2-12)7.5 (3-12)Time since diagnosis (months), Mdn (IQR)0 (0-1)0 (0-1)4 (3-4)RF-positivity, n (%)8 (11)3 (8)Number of active joints (arthritis), Mdn (IQR)7 (4-12)7 (5-12)2 (0-4)JADAS10 (0-40), Mean (SD) (NBL+3FU= 23)18.6 (7.4)19.6 (7.6)7.2 (4.2)cJADAS10 (0-30), Mean (SD) (NBL+3FU= 29)16.3 (5.9)16.7 (6.1)7.1 (4.1)State of inactive disease (cJADAS10≤2.5), n (%*)0 (0)0 (0)4 (13)State of minimal disease activity (2.5<cJADAS10≤5), n (%*)1 (2)1 (3)9 (28)State of moderate disease activity (5<cJADAS10 ≤16), n (%*)33 (54)17 (50)18 (56)State of high disease activity (cJADAS10>16), n (%*)27 (44)16 (47)1 (3)CHAQ (0-3), Mean (SD)0.8 (0.8)0.9 (0.8)0.3 (0.5)Pain (NRS 0 - 10), Mean (SD)4.3 (3)4.7 (3)2.2 (2.7)PedsQL 4.0 total score, Mean (SD)66.3 (22.2)65.4 (21.8)78.4 (17.6)Intraarticular glucocorticoids > 4 joints (ever), n (%)12 (16)5 (13)7 (18)Glucocorticoid pulses (ever), n (%)22 (29)12 (32)13 (34)Methotrexate, n (%)56 (74)31 (82)34 (90)bDMARDs, n (%)7 (9)2 (5)9 (24)Within the first 3 months after diagnosis, the treatment pathways proposed by the ProKind Commission [1] were followed in about three-quarters of patients: i) 5 (13%) received MTX and intra-articular glucocorticoid injections in more than 4 joints (IAGC), but no high-dose intravenous glucocorticoid pulse (HDGC) or bDMARD; ii) 8 (21%) received MTX and HDGC (no bDMARD, no IAGC); iii) 16 (42%) patients received MTX, of whom 4 received a bDMARD up to or at the 3FU (no HDGC, no IAGC). Nine (24%) patients were not treated with MTX or did not fit any of these categories, mostly due to starting bDMARD therapy in conjunction with HDGC or IAGC.ConclusionIn the routine care of JIA patients with polyarthritis, the proposed treatment protocol and treat-to-target strategy are followed in most patients. At 3FU, improvements of JADAS10 and other outcomes were evident, with 41% having achieved inactive or minimal active disease.ProKind is funded by the Innovation Fund “Gemeinsamer Bundesausschuss”, FKZ: 01VSF18031References[1]Horneff et al.

Abstract
BACKGROUND Autopsies are a valuable tool for understanding disease, including COVID-19. MATERIALS AND METHODS The German Registry of COVID-19 Autopsies (DeRegCOVID), established in April 2020, serves as the electronic backbone of the National Autopsy Network (NATON), launched in early 2022 following DEFEAT PANDEMIcs. RESULTS The NATON consortium's interconnected, collaborative autopsy research is enabled by an unprecedented collaboration of 138 individuals at more than 35 German university and non-university autopsy centers through which pathology, neuropathology, and forensic medicine autopsy data including data on biomaterials are collected in DeRegCOVID and tissue-based research and methods development are conducted. More than 145 publications have now emerged from participating autopsy centers, highlighting various basic science and clinical aspects of COVID-19, such as thromboembolic events, organ tropism, SARS-CoV‑2 detection methods, and infectivity of SARS-CoV-2 at autopsy. CONCLUSIONS Participating centers have demonstrated the high value of autopsy and autopsy-derived data and biomaterials to modern medicine. The planned long-term continuation and further development of the registry and network, as well as the open and participatory design, will allow the involvement of all interested partners.

Abstract
The properties of quantum materials are commonly tuned using experimental variables such as pressure, magnetic field and doping. Here we explore a different approach using irreversible, plastic deformation of single crystals. We show that compressive plastic deformation induces low-dimensional superconductivity well above the superconducting transition temperature (Tc) of undeformed SrTiO3, with evidence of possible superconducting correlations at temperatures two orders of magnitude above the bulk Tc. The enhanced superconductivity is correlated with the appearance of self-organized dislocation structures, as revealed by diffuse neutron and X-ray scattering. We also observe deformation-induced signatures of quantum-critical ferroelectric fluctuations and inhomogeneous ferroelectric order using Raman scattering. Our results suggest that strain surrounding the self-organized dislocation structures induces local ferroelectricity and quantum-critical dynamics that strongly influence Tc, consistent with a theory of superconductivity enhanced by soft polar fluctuations. Our results demonstrate the potential of plastic deformation and dislocation engineering for the manipulation of electronic properties of quantum materials.

Abstract
Oral tolerance blocks the development of specific immune responses to proteins ingested by the oral route. One of the first registries of oral tolerance showed that guinea pigs fed corn became refractory to hypersensitivity to corn proteins. Mice fed with chow containing corn are tolerant to zein, and parenteral injection of zein plus adjuvant blocks immunization to unrelated proteins injected concomitantly and reduces unspecific inflammation. Extensive and prolonged inflammatory infiltrate in the wound bed is one of the causes of pathological wound healing. Previous research shows that intraperitoneal injection of zein concomitant with skin injuries reduces the inflammatory infiltrate in the wound bed and improves wound healing. Herein, we tested if one subcutaneous injection of zein before skin injury improves wound healing. We also investigated how long the effects triggered by zein could improve skin wound healing. Mice fed zein received two excisional wounds on the interscapular skin under anesthesia. Zein plus Al(OH)3 was injected at the tail base at 10 min, or 3, 5, or 7 days before skin injuries. Wound healing was analyzed at days 7 and 40 after injury. Our results showed that a zein injection up to 5 days before skin injury reduced the inflammatory infiltrate, increased the number of T-cells in the wound bed, and improved the pattern of collagen deposition in the neodermis. These findings could promote the development of new strategies for the treatment and prevention of pathological healing using proteins normally found in the common diet.

Abstract
Abstract
Background
Recurrent pericarditis (RP) patients report that painful, debilitating flares negatively impact their health-related quality of life (HRQoL). RHAPSODY, the Phase 3 trial of rilonacept (IL-1α/IL-1β cytokine trap), included a daily pain diary and patient-reported outcome SF-36v2 to measure HRQoL throughout the trial.
Purpose
The purpose of this research is to evaluate the effect of rilonacept on HRQoL in relation to changes in pain for RP patients who have a recurrence.
Methods
RHAPSODY enrolled 86 patients with acute symptomatic RP to receive weekly rilonacept for a 12-week run-in (RI) period and randomized 61 patients (1:1) to receive placebo (n=31) or continue rilonacept (n=30) for the event-driven randomized-withdrawal (RW) period. Patients on placebo who experienced a qualifying recurrence during RW (return of pericarditis pain and increase in C-reactive protein) were rescued with bailout rilonacept. Patients reported daily pericarditis pain electronically, using a 0–10 numeric rating scale (NRS), and completed the SF-36v2 at study visits prior to clinician interaction. Scores from RI Baseline (BL), RI Week 12 (RW BL), Recurrence visit, and RW up to Week 24 (or end of study; EOS) were evaluated for patients who experienced recurrence in RW. Analyses exclude one patient randomized to placebo who had a recurrence after Week 24 of the RW period.
Results
Analyses focused on the 22 of 30 patients (73%) in the placebo group who experienced a recurrence before Week 24 of RW (median time from RW BL to recurrence: 8.6 weeks). During RI, daily pain scores decreased while on rilonacept (Cohen's effect size [ES] d=−2.0), and SF-36v2 scores improved, with scores at RI BL (Fig. 1 red line) below the general population average of 50 and near or above average at RI Week 12 (Fig. 1 blue line); ES were all large (d>0.8), ranging from 0.917 (Mental Component Summary) to 2.021 (Bodily Pain). At recurrence, pain scores increased (d=6.5; Fig. 2) and SF-36v2 scores were below the population average (Fig. 1 orange line), with largest reductions between RI Week 12 (RW BL) and recurrence for Bodily Pain (−13.4) and Physical Component Summary (−10.6). Following rilonacept bailout, average pain decreased (d=−2.1; Fig. 2), and by RW Week 24/EOS, SF-36v2 scores returned to similar levels as at the end of the RI period (Fig. 1 green line).
Conclusion
Impaired RI BL SF-36v2 scores indicate negative impact of RP on HRQOL in RP patients. While receiving rilonacept, HRQoL scores improved to near or above population averages, in conjunction with patient-reported pain. After discontinuing rilonacept during RW, HRQoL scores worsened at recurrence and improved upon receipt of bail-out rilonacept, similar to pain. These results provide support for the broader benefit of rilonacept treatment beyond pain, when administered on top of conventional therapies and as mono-therapy, providing evidence of its potential to improve HRQoL in this patient population.

Abstract
Abstract
Background
Left Atrial (LA) phasic volumes analyses is flawed with geometrical assumption requiring high endocardial border definition. LA strain analysis is an emergent technique that overcome some of these technical limitations. Prior studies of LA mechanics in pericardiectomy patients found improvement in LA strain at follow-up and manifested as symptomatic improvement, however their relationships with survival have not been investigated.
Purpose
We assessed LA strain before and after pericardiectomy and its association with all- cause mortality.
Methods
Consecutive patients with constrictive pericarditis who underwent pericardiectomy from 2000–2017 were retrospectively analyzed, analyzing pre-operative and post-operative (at 12 months) echocardiography. Exclusion criteria included atrial fibrillation, previous left sided valve surgery, concomitant valvular surgery at the index pericardiectomy, more than mild left sided valvulopathy and poor echocardiographic windows. Strain analyses was performed with Vector velocity imaging independent software. Univariate and multivariable analyses were utilized to identify factors associated with reduced survival.
Results
Amongst 190 patients included in the analyses, mean age was 58.5±12.7 years and 37 (19.5%) were female. The etiology of constriction was deemed idiopathic in 61.6% of the cases, median time interval surgery-postoperative echo was 67 days (IQR 6, 312 days). During median follow up of 3.3 years (IQR 0.73, 5.9 years) there were 37 deaths. After surgery, there was a significant decrease in LA reservoir, conduit and regional wall strains. (Table 1). Multivariable analysis demonstrated that postoperative 4C AL strain reservoir was independently associated with all-cause mortality (Table 2).
Conclusions
In pericardiectomy patients, postoperative 4C LA strain reservoir is independently associated with all-cause mortality. Perhaps, compensatory changes of septal and antero-posterior walls during constriction explain why after surgery these walls become less dynamic, negatively impacting the overall function. Overall, LA quantification and strains may become a useful clinical tool for risk stratification in pericardiectomy patients

Abstract
Abstract
Background
Annually in the United States (US), an estimated 80–90,000 patients are diagnosed with acute pericarditis and 15–30% experience recurrent pericarditis (RP), resulting in increased morbidity and reduced health-related quality of life (HRQoL). Treatment options include non-steroidal anti-inflammatory drugs (NSAIDs) and colchicine. Corticosteroids (CS) are often added to the treatment plan in RP despite CS-associated adverse events and inherent potentiation of recurrence with long-term treatment. A recent Phase 3 clinical trial RHAPSODY (NCT03737110) demonstrated efficacy and safety of rilonacept, an interleukin-1 α and β cytokine trap, in patients with RP. RHAPSODY data helped support FDA approval of the first therapy for RP. With the emergence of this targeted therapy, there is increased interest to learn more about this disease with the goal to better inform treatment and management decisions and improve long-term outcomes.
Purpose
RESONANCE Registry aims to evaluate the natural history of RP by collecting retrospective and prospective, longitudinal physician- and patient-reported outcomes data in real-world clinical practice across the US.
Methods
RP patients with active disease (recurrence within 3 years) will have both retrospective and prospective data collected (Figure 1) for as long as their RP is managed up to 5 years. For patients with inactive disease (no recurrence within 3 years), data collection will be retrospective (Figure 2). Up to 500 patients in the US are planned for enrollment at pediatric and adult medical centers, with the potential for expansion to European sites. Additionally, patients will be recruited through a novel, internet-based technology platform and screened for eligibility at a “decentralized” trial site. The registry will include variables obtained from health records, including baseline characteristics and medical history, as well as patient reported outcome (PRO) measures collected every 3 months. The RESONANCE protocol is designed to include a broad population of pediatric and adult patients, regardless of etiology or treatment course, including patients treated with rilonacept. Data will be analyzed to understand disease heterogeneity, variability in treatment and management, and impact on HRQoL. The protocol and Case Report Forms (CRFs) were developed in collaboration with physicians, patients, and patient advocates.
Conclusions
Registries utilize real-world data to fill knowledge gaps in the management of less common diseases such as RP. The RESONANCE Registry is the first RP registry designed to collect data across a broad range of patients regardless of treatment. The registry will also serve as a connection point for physicians to further educate and empower patients with information about their disease. In addition, PRO data may enable greater insights into the understanding of the burden of RP from the patient's perspective.

Abstract
Abstract
Background
Corticosteroid-dependent and colchicine-resistant recurrent pericarditis (RP) is a challenging management problem, in which conventional anti-inflammatory therapy (nonsteroidal anti-inflammatory drugs, colchicine, corticosteroids) is unable to control the disease. Recent data suggest a potential role for anti-interleukin-1 (IL-1) agents for this condition.
Purpose
This study was designed to assess the safety and efficacy of anti-IL-1 agents in this setting.
Methods
We performed a systematic review and meta-analysis of randomised controlled trials and observational studies assessing pericarditis recurrences and drug-related adverse events in patients receiving anti-IL-1 drugs for pericarditis.
Results
The meta-analysis assessed 7 studies including 397 pooled patients with RP. The median age was 42 years, 60% were women and the aetiology was idiopathic in 87%. After a median follow-up of 14 months (IQR,12–39), patients receiving anti-IL-1 agents (anakinra or rilonacept) had a significantly reduction in pericarditis recurrences (incidence rate ratio 0.06, 95% CI 0.03 to 0.14, see figure), compared with placebo and/or standard medical therapy. Anti-IL-1 agents were associated with increased risk of adverse events compared with placebo (risk ratio (RR) 5.38, 95% CI 2.08 to 13.92): injection-site reactions occurred in 15/41 (36.6%) vs. none (RR 14.98, 95% CI 2.09 to 107.09), infections occurred in 13/51 (25.5%) vs. 3/41 (7.3%; RR 3.65, 95% CI 1.23 to 10.85). Anti-IL-1 agents were not associated with increased risk of severe adverse events.
Conclusions
In patients with RP, anti-IL-1 agents (anakinra and rilonacept) are efficacious for prevention of recurrences, without severe adverse events.

Abstract
Background:COVID-19 is a major challenge worldwide. Although the risk for a severe disease course is low among children with COVID-19, symptoms may be exacerbated by underlying disease and/or immunosuppressive medication. We analysed clinical data from COVID-19 cases in among pediatric patients with juvenile idiopathic arthritis (JIA) in Germany reported to the BIKER registry.Objectives:This is an analysis of clinical data for 56 COVID-19 cases reported to the German BIKER registry from 29 German pediatric rheumatology centers and clinics from February 2020 to January 2021.Methods:The major task of the German BIKER (Biologics in Paediatric Rheumatology) Registry is surveillance of biologics used in pediatric rheumatology patients. Following the start of the COVID-19 pandemic in Germany, a survey was established to proactively interview all participating centers regarding the occurrence, presentation and outcome of SARS-CoV-2-infected children with rheumatic diseases. Initially, the interviews were conducted in weekly intervals, later bi-weekly.A standardized Adverse Event of Special Interest form was developed requesting biographic data, pre-treatment, current medication, data on clinical presentation, course, treatment and outcome of COVID-19 pediatric rheumatology patients.Results:In all, 56 patients with JIA and SARS-CoV-2 infection were reported (Table 1). Of these patients, 71% were 12 or more years old.Table 1.Patient characteristics. COVID-19 positive patients.JIA patients, n=56n (%)Age 0-5 years / 6-11years / 12-18years3 (5.4) / 13 (23.2) / 40 (71.4)JIA category•Systemic JIA5 (8.9)•Oligoarthritis JIA9 (16)•Polyarticular JIA32 (57)•Enthesitis-related JIA2 (3.6)•Psoriatic JIA1 (1.8)•Unknown7 (12.5)Uveitis (concomitant)4 (7.1)Treatment•DMARD / MTX23/ 22 (41/39)•Biologics29 (52)•TNF inhibitors20 (36)•Tocilizumab5 (8.9)•Abatacept1 (1.8)•Anakinra1 (1.8)•Ustekinumab1 (1.8)•JAK inhibitors1 (1.8)•Steroids5 (8.9)Asymptomatic13 (23.2)Hospitalized/ICU/Ventilation/Death1/1/1/1 (1.8)At the time of infection, 41% of the patients received conventional DMARDs and 52% received biologics (Table 1). Forty-four patients (79%) received either a conventional DMARD or a biologic. Most patients had a polyarticular course of their JIA (57%).In 49 of the 56 cases (88%) COVID-19 was detected directly by PCR (n=46), by antigen test only (n=1) or an undisclosed method (n= 2). Six patients had detectable SARS-CoV2 antibodies and reported to have had typical symptoms. One patient tested negative but developed typical symptoms at approximately the same time a positive SARS-CoV-2 test was returned for a family member.Symptoms were reported in 43 of the 56 patients (77%): fever n=15, rhinitis n=14, cough n=12, headache n=10, loss of sense of taste and/or smell n=9, pharyngitis n=8, fatigue n=5, musculoskeletal pain n=5, GI symptoms n=2 (abdominal pain n=1, diarrhoea n=1), dizziness n=3, encephalitis/seizure/respiratory failure/death n=1. Thirteen patients (23%) were asymptomatic.A 3½ -year-old female patient initially diagnosed with systemic JIA developed intracranial oedema and respiratory failure. Her SARS-CoV2 PCR test was positive and pulmonary imaging displayed typical changes in lung texture. Before her SARS-CoV-2 infection, the patient was treated with methotrexate and low-dose steroids. Unfortunately, she died three days following hospital admission. Genetic testing revealed an inborn immunodeficiency. Except for this one patient, all other cases were treated as outpatients and no deaths were reported.Conclusion:Apart from one patient with an inborn immunodeficiency who died from her COVID-19 infection, no case of hospitalization or severe COVID-19 was reported in our cohort of JIA patients. At the time of COVID-19 diagnosis, nearly 80% of patients in our cohort had been treated with conventional DMARD and/or biologics. This seemed not to have a negative effect on severity or outcome of SARS-CoV2 infection.Acknowledgements:Thanks also for contributing Reports for this analysis to: Normi Brück, Frank Dressler, Ivan Foeldvari, Tilman Geikowski, Hermann Girschick, Johannes-Peter Haas, Tilmann Kallinich, Bernd-Ulrich Keck, Eggert Lilienthal, Anna-Hedrich Müller, Ulrich Neudorf, Nils Onken, Peggy Rühmer.Disclosure of Interests:None declared.

Abstract
Background:In polyarticular juvenile idiopathic arthritis (pJIA) biologic therapies are often combined with methotrexate (MTX). This combination was shown to increase efficacy in adult rheumatoid arthritis patients. MTX may also have a protective effect on the formation of anti-drug antibodies and thus may prolong drug survival. In pJIA, there are few and sometimes controversial data available.Objectives:To compare the effect of combination treatment with MTX on discontinuation due to inefficacy and on drug survival discontinuation of biologics approved for first line treatment of pJIA.Methods:Patients from the German BIKER registry with their first treatment course with Adalimumab, Etanercept, Golimumab or Tocilizumab were selected. Rates of ineffectiveness-related withdrawal were analysed and compared using χ2-test, Wald-test and Kaplan-Meier analysis of patients receiving biologic monotherapy or concomitant methotrexate. Cases were censored if MTX was discontinued before the biologic.Results:2173 pJIA patients were identified who for the first time received a biologic. Etanercept (ETA) was by far the most frequently used biologic for first line biologic treatment in pJIA (77%) followed by Adalimumab (ADA, 16%). Patients on Golimumab (GOL) received most frequently a combination with MTX (86.5%), while patients on Tocilizumab (TOC) had the lowest rate of combination treatment (53%).ETA/ADA/GOL/TOC was given as monotherapy in 500(30%)/89(26%)/5(13.5%)/46(47%) and combined with MTX in 1179 (70%)/259(74%)/32(86.5%)/51(53%) cases. More patients with rheumatoid-factor negative (54 vs 50%; p=0.04) and rheumatoid-factor positive pJIA (13 vs 10%, p=0.04) received combination with MTX, while more patients in the monotherapy cohort had extended oligoarthritis (40 vs 32%, p<0.001). Patients with MTX had a shorter disease duration (4 vs 5.5years, p<0.001) and received concomitant steroid more often (34 vs 24%), p<0.001). There was no statistical difference regarding disease activity parameters (active joint count, patient assessment and physician assessment of disease activity, ESR, CRP, CHAQ-DI, JADAS10). Discontinuation due to ineffectiveness was reported for ETA/ADA/GOL/TOC in 20%/18%/14%/28% of patients, respectively in 3.7/4.9/6/10.5 patients/100 treatment years. Thus discontinuation due to inefficacy was reported less frequently with ETA compared to ADA (p=0.046) and TOC (p<0.001) and with ADA compared to TOC (p<0.001).Patients on ETA and ADA had a slightly, but not statistically significant lower rate of withdrawal for ineffectiveness if on methotrexate (Figure 1). There was no difference regarding baseline disease activity parameters in patients with ETA/ADA monotherapy compared with combination with MTX, apart from patients with ETA+MTX receiving more often systemic steroids at baseline (36vs 24%,p<0-001). For both GOL and TOC treatment, no baseline differences in disease activity between cohorts with monotherapy and MTX combination could be shown. The combination with MTX led to significantly lower rates of discontinuation due to inefficacy (p<0.05) with GOL and TOC (Figure 1).Conclusion:Patients with pJIA mostly were treated with a combination of the biologic and MTX rather than with biologic monotherapy. Treatment was discontinued due to lack of efficacy in 14% to 28%. No statistically significant effect of combination treatment with MTX versus monotherapy could be observed regarding the rate of treatment failures in patients treated with ETA or ADA. However, combination treatment with MTX significantly prolonged the survival of GOL and TOC in patients with polyarticular JIA. The results are limited by low patient numbers in the GOL cohort and possible bias by JIA category.Figure 1.Kaplan Meier plot of drug survival in patients with monotherapy or with combination with MTX of the indicated biologicDisclosure of Interests:Gerd Horneff Speakers bureau: MSD, Grant/research support from: Pfizer, Roche, Chugai, MSD, Daniel Windschall: None declared, Kirsten Minden Speakers bureau: Pfizer, Abbvie, Grant/research support from: Pfizer, Toni Hospach: None declared, Frank Dressler: None declared, Frank Weller-Heinemann: None declared, Boris Huegle: None declared, Ivan Foeldvari Speakers bureau: Pfizer, Ariane Klein: None declared

Abstract
Background:Golimumab (GOL) is approved for treatment of polyarticular juvenile idiopathic arthritis (pJIA) in patients 2 years and older. Data on long-term safety of GOL in this indication are limited.Objectives:To assess long-term safety and efficacy of GOL in pJIA patients.Methods:In this ongoing non-interventional observational study, clinical characteristics, disease activity and safety parameters were analysed using the German Biologics in Paediatric Rheumatology (BiKeR) registry. 81 pJIA-patients treated with GOL were body weight-matched with 162 patients receiving alt. tumor necrosis factor inhibitors (TNFi) and 81 biologic–naïve patients under methotrexate (MTX)-therapy.Results:Baseline parameters of GOL patients differed from the alternative TNFi and MTX cohorts. In patients starting with GOL treatment, disease duration was longer, corticosteroid use was less and disease activity, measured by the mean number of active joints and the JADAS10, was lower (Table 1).The long-term clinical efficacy of GOL in pJIA is highlighted by a decrease of the mean JADAS 10 from 11.6 (baseline) to 5.2 after 24 months. After 2 years, a JADAS 10 minimal disease activity was reached by 44.4 % of patients, whereas 22.2 % of patients were in remission and the JIA ACR 30/50/70/90 response rates were 77.8/72.2/66.7/55.6% respectively.AE, SAE and infectious AE rates between the three cohorts were comparable (Table 1). In the GOL cohort, 4 SAE (1 uveitis, 1 arthritis flare, 1 fibromyalgia syndrome and 1 abscess) were reported, while in the alt. TNFi group 7 SAEs and in the MTX cohort 1 SAE were noted (Table 1).

Abstract
Background:Juvenile idiopathic arthritis (JIA) associated uveitis is an extra-articular manifestation of the JIA disease that may cause vision-threatening complications and an uncontrolled uveitis may even lead to blindness. Uveitis occurs in up to 20% of patients with JIA, depending on the JIA category. The majority of patients develop uveitis within the first two years after JIA symptom onset, but uveitis can continue into adulthood.Objectives:The main objective of this study was to analyze the risk for uveitis events after discontinuing disease-modifying antirheumatic drugs (DMARD) in patients with extended oligoarthritis and rheumatoid factor (RF)-negative polyarthritis.Methods:Data of the two ongoing multicenter biologic registers: German Biologics in Pediatric Rheumatology (BiKeR) and the Juvenile arthritis Methotrexate/Biologics long-term Observation (JuMBO) were used to analyze the adverse-event (AE) and events of special interest (ESI) reports about uveitis events during treatment and after discontinuation of DMARDs. Biker started recruitment of children and adolescent patients with JIA exposed to biological (b) or conventional (cs) DMARD’s in 2001. The patients were further followed in JuMBO after reaching the age of 18 or transitioning to an adult rheumatologist. Disease characteristics, treatment data, AE’s and ESI’s were reported by the pediatric or adults rheumatologist, respectively.Results:A total of 2,041 patients with RF-negative polyarthritis (n=1,280) or extended oligoarthritis (n=761) were included into the analyses. The mean follow-up of this study was 7.6 years (SD 5.3). About half of the patients were enrolled in BiKeR with start of etanercept (1,137, 55.7%), followed by 635 (31.1%) patients with start of methotrexate (MTX) monotherapy or adalimumab (ADA, n=198, 9.7%). A history of uveitis was reported for 238 (11.7%) patients at enrolment in BiKeR. More patients with a history of uveitis treated with ADA were included in BiKeR initiating ADA (n=98 of 238, 41.2%). Patients with uveitis had a lower age at JIA onset in comparison to patients without uveitis (mean 3.6 (SD 3.0) versus 7.0 (SD 4.5) years). A total of 142 recurrent (84% of 169) uveitis events were reported in 93 patients and for 27 patients (1.3% of 2,041) was an incident uveitis reported during follow-up. More than one uveitis event was reported for 32 patients with a maximum number of 4 uveitis flares in 3 patients. Nineteen uveitis flares (11.2% of 169) were reported for patients after the age of 18. The longer the time since DMARD discontinuation the fewer uveitis events occurred. Uveitis events were significantly more often reported in the first 24 months after MTX discontinuation (<6 months: OR=3.19, 95%CI: 1.70 to 5.96; 6 to <12 months: OR=2.06, 95%CI: 1.01 to 4.66; 12 to <24 months: OR=2.20, 95%CI: 1.14 to 4.25) and in the first three months after biological DMARD discontinuation (OR=5.4, 95%CI: 1.56 to 18.33). Patients with a MTX dose of ≤ 10 mg/m2 at last MTX intake had a higher likelihood for uveitis events (OR=1.40, 95%CI: 1.02 to 1.92).Conclusion:This is the first study that analyzed the risk of uveitis after DMARD withdrawal. Uveitis relapses are common. Patients who discontinued DMARD therapy were at high risk for uveitis within the first 3 to 24 months after discontinuation. Rheumatologists and ophthalmologists should be aware about this risk which should lead to a regular uveitis screening after DMARD withdrawal.Disclosure of Interests:Jens Klotsche: None declared, Ariane Klein: None declared, Martina Niewerth: None declared, Tilmann Kallinich: None declared, Daniel Windschall: None declared, Johannes-Peter Haas: None declared, Frank Weller-Heinemann Speakers bureau: Pfizer, Abbvie, SOBI, Roche, Novartis, Toni Hospach: None declared, Frank Dressler: None declared, Kirsten Minden: None declared, Gerd Horneff: None declared

Abstract
Background:In 2017, 2 Etanercept biosimilars became approved. Comparative studies performed in adult patients with rheumatoid arthritis, ankylosing spondylitis or psoriasis by extrapolation led to approval for juvenile idiopathic arthritis (JIA).Objectives:So far there is limited experience with Etanercept biosimilars in JIA: The large national data base of the BIKER-registry was used to describe experience with Etanercept biosimilars in clinical practice.Methods:In this retrospective analysis patients exposed to ETA were identified in the German BIKER-registry and grouped into cohorts according to initiation of treatment after 2017, use of the originator and of biosimilars. The course of JADAS10, Physician global assessment VAS 0–100-mm, Parent/patient global assessment VAS 0–100-cm, Active joint count 0-71, truncated at 10, ESR and CHAQ-DI was analyzed. Descriptive statistics was used for demographic, clinical data, drug exposure, adverse events (AEs) and events of special interest (ESI).Results:Until 31.10.2020, 2917 JIA patients were reported to have received Etanercept. Since January 1 2017, in 39 centres treatment with Etanercept was started in 439 patients (377 (85.9%) started with the originator and 62 (14.1%) started a Biosimilar). Biosimilars were prescribed n 17 centres (44%). In 12 centres (31%), Etanercept biosimilars were used first line in 62 patients. In 17 centres (44%), 63 patients switched for the originator to a biosimilar. 3 patients reswitched from the biosimilar to the originator. 4 patient switched from a biosimilar to the originator). 22 centres (56%) had not prescribed a biosimilars so far.In not a single centre, initiation of a biosimilar was more frequent than of the originator.The patients’ characteristics and disease activity parameters were widely comparanble. Patients receiving biosimilar first line were slightly older at disease onset and had a longer disease duration. Patients receiving biosimilar first line had more often rheumatoid factor (RF) negative polyarthritis while extended oligoarthritis was more frequent in the originator cohort. In the switching cohort, more patients had extended oligoarthritis and fewer had RF negative polyarthritis and ERA JIA.No difference in disease activity parameters was noted, neither at baseline, during the course of treatment nor at last observation upon treatment. A decrease of the JADAS10 indicates improvement in both groups (Figure 1). At the time of switching, 68% had JADAS minimal disease activity (MDA) and 43% were in JASDAS remission. At month 6 and 12 these numbers increased to 74%/65% and 62%/50%.In total, 66 adverse events (AE) were reported in 45 patients upon biosimilar treatment.33 patients had 1, 5 patients 2, 5 patients had 3 and 2 reported 4 events. Adverse event of special interest were hypersensitivity n=1, injection site reaction n=1, new onset of psoriasis n=1, celiac disease n=1, Crohn‘s diesease n=1, elevated transaminases n=2, depression n=1 and disease deterioration (arthritis flare) in n=21. In 20 patients, the etanercept biosimilar was discontinued.Conclusion:This analysis is the first attempt to present a large data sample on JIA patients exposed to Etanercept biosimilars. Biosimilar were used in a minority of patients and by a minority of centers although no difference in efficacy or safety was noted from our analysis. Until today, the use of the originator is by far exceeding the use of biosimilars. The prescription of a biosimilar either first line or by switching from the originator is limited to a part of centres. Differences in efficacy between first line biosimilar users and originator users could not be observed. Also, after switching, no loss of efficacy was observed.Disclosure of Interests:Gerd Horneff Speakers bureau: Pfizer, Daniel Windschall: None declared, Toni Hospach: None declared, Sonja Mrusek: None declared, Michael Rühlmann: None declared, Ariane Klein: None declared

Abstract
Background:In 2017, Adalimumab Biosimilars became approved. Comparative studies to the originator have been performed in adult patients with rheumatoid arthritis, ankylosing spondylitis and psoriasis and extrapolation led to approval for juvenile idiopathic arthritis (JIA).Objectives:So far there is limited experience with biosimilars in JIA: The large national data base of the BIKER-registry was used to describe experience with Adalimumab biosimilars in clinical practiceMethods:This retrospective analysis used data of the German BIKER-registry. The data basis war screened for patients exposed to Adalimumab. Subcohorts with initiation of treatment after 2017, use of the originator and of biosimilars were built. The course of JADAS10, Physician global assessment VAS 0–100-mm, Parent/patient global assessment VAS 0–100-cm, Active joint count 0-71, truncated at 10, ESR and CHAQ-DI was analyzed. Descriptive statistics was used for demographic, clinical data, drug exposure, adverse events (AEs) and events of special interest (ESI).Results:Until 31.10.2020, 1173 JIA patients were reported to have received Adalimumab. 352 treatments have been started after January 1, 2017. A biosimilar was used first line in 44 patients. Further 55 patients switched for the originator to a biosimilar. 2 patient switched from a biosimilar to the originator. 3 patients switched to a second biosimilar while 5 patients who switched from the originator to a biosimilar reswitched back to the originator.After 2017, 33 pediatric rheumatology centres reported initiation of Adalimumab treatment. 17 have used a biosimilar. 15 centres have swichted at least 1 patient from the originator to a biosimilar and 14 have used first line a biosimilar in at least 1 patient. In a single centre, initiation of a biosimilar was used more frequently (8 versus 7).The patients’ characteristics and disease activity parameters were brightly comparable. The JIA category rheumatoid factor (RF) negative polyarthritis was less frequent in the biosimilar first cohort while RF positive polyarthritis and psoriatic arthritis was more frequent. In patients with idiopathic uveitis the originator was used more often. In the switching cohort, more patients had RF negative polyarthritis, persistent oligoarthritis but less had psoriatic arthritis and no had RF positive polyarthritis.No difference in disease activity parameters between patients receiving the originator or biosimilars were noted, neither at baseline, during the course of treatment nor at last observation upon treatment (Figure 1). At the time of switching, 46 (92%) had JADAS minimal disease activity (MDA) and 30 (69%) were in JASDAS remission. At last observation, those numbers were comparable with 42 (86%) with JADAS MDA and 28 (57%) with JADAS remission.In total, 45 adverse events (AE) were reported in 45 patients upon biosimilar treatment. 26 patients had 1, 12 patients had 2 and 6 patients reported 3 and 1 reported 4 events. Adverse event of special interest were Infection associated leukopenia (n=1), COVID 19 infection (n=1), Uveitis flare (n=8), other disease deterioration (arthritis flare) (n=20), injection site reaction n=2. A single serious AE was reported. A 16 year old female adolescent was admitted for unexpected CK elevation. In 10 patients, Adalimumab was discontinued, in 2 it was temporarily paused.Conclusion:This article is the first attempt to present a large sample of data on JIA patients exposed to Adalimumab biosimilars. Since approval of Adalimumab-Biosimilars, limited experience from clinical practice is available. Biosimilars are used in a minority of patients and by a minority of centers although no difference in efficacy or safety was noted from our analysis.Disclosure of Interests:Gerd Horneff Speakers bureau: Novartis, MSD, Sobi, Grant/research support from: MSD, Roche, Frank Dressler: None declared, Michael Rühlmann: None declared, Tilmann Geikowski: None declared, Sonja Mrusek: None declared, Ariane Klein: None declared

Abstract
Background:Although children and adolescents are less likely to develop COVID-19 and generally show milder disease courses, it is unclear what impact the SARS-CoV2 infection has on children and adolescents with rheumatic and musculoskeletal disease (RMD). Due to their underlying disease as well as therapeutic immunosuppression these patients may be at higher risk of being more severely affected by SARS-CoV2. Furthermore, SARS-CoV2 infection might trigger a flare of the underlying disease.Objectives:To evaluate clinical characteristics and disease course of COVID-19 in children and adolescents with RMD and to analyze possible effects of SARS-CoV2 infection on the underlying disease under different therapeutic regimens.Methods:Data from juvenile patients with RMD recorded via the SARS-CoV2 questionnaire within the National Pediatric Rheumatology Database and the registry for hospitalized children and adolescents with COVID-19 of the German Society for Pediatric Infectious Diseases were analyzed. In addition to age, sex and diagnosis, information was collected about the date and method of a positive SARS-CoV2 testing, reason for testing, on clinical manifestations, disease course, treatment and outcome of COVID-19, on drug therapy at the time of virus detection, on disease activity (NRS 0 – 10, 0 = best) of the underlying disease at the last visit before and after the SARS-CoV2 infection.Results:From April 17th 2020 until January 25th 2021, data of 67 patients with RMD and confirmed SARS-CoV2 infection were collected. Mean age was 13.5 ± 3.9 years with equal sex distribution. The majority of patients were diagnosed with juvenile idiopathic arthritis (JIA, 64%), 12 (18%) patients had an autoinflammatory disease (FMF, CAPS, PFAPA, TRAPS) and 5 (7%) a connective tissue disease. Fifty-two patients (78%) were treated with a disease modifying antirheumatic drug (DMARD), 39% with a biological DMARD and 9% systemic glucocorticoids at the time of SARS-CoV-2 infection. Nineteen patients (28%) were tested for SARS-CoV-2 because of typical symptoms, the majority (67%) because of contact to an infected person. PCR was used most often (in 60 %).52 patients (78%) developed symptoms of COVID-19, 15 patients remained asymptomatic. The most common symptom of COVID-19 was rhinitis (42%) and fever (38%), followed by fatigue (34%), taste/smell disorder (33%), sore throat (27%) and cough (23%).Disease severity was graded as mild in 44 of 52 (85%) symptomatic patients, only two patients were hospitalized, one of whom required intensive care and died of cardiorespiratory failure 3 days after symptom onset. In 22 of 26 (85%) SARS-CoV2-positive patients, no relevant increase in disease activity (difference in NRS ≤ 1 before/after infection) of the underlying disease was observed 31 days after symptom onset (median, IQR 17-52 days). One patient, who had paused tocilizumab for 2 doses, experienced a flare of his seronegative polyarthritis 2 months after asymptomatic SARS-CoV-2 infection.Conclusion:In our cohort, the clinical picture of COVID-19 in children and adolescents with RMD was similar to that of healthy peers. The majority of patients showed mild disease course with good outcome under various medications, however, one patient with a severe course of COVID-19 died. In addition, SARS-CoV2 infection does not appear to have a relevant impact on the underlying disease activity, whereas discontinuation of therapy might pose a risk of flare.Disclosure of Interests:None declared.

Abstract
INTRODUCTION The early identification and access to health care of toddlers with autism spectrum disorder (ASD) - or at risk of developing it - is a crucial public health issue, as care and intervention may be more effective in younger children in order to improve their development and prognosis. However, there are still disparities in identification and health care access for children with ASD despite better screening methods. Given that misdiagnosis and delayed diagnosis are often due to the cultural gap between clinician and patient in some psychiatric disorders such as depression or schizophrenia, we examined this question concerning ASD and wondered to what extent ethno-cultural or migratory status might have an impact on the age at which a child is diagnosed. The only published review looking for independent factors influencing age of diagnosis concludes that the factors that have been proved to play a role are: socioeconomic status; symptom severity; level of parental concern, and family interactions with the health and education systems prior to diagnosis. The impact of ethno-cultural or migratory status is less clear. And yet, all these factors may be interconnected: migrants have on average a lower socioeconomic status, minorities don't have the same access to health care, and cultural background can have an influence on what is expected of a child's development and health. In order to try and clarify this issue and to analyze the way in which the international literature approaches the subject, we carried out a systematic review. METHOD Six databases were interrogated: Pubmed, Embase, Psychinfo, WebOfScience, Cochrane and Cinahl using the key words "ASD", "pervasive developmental disorder", "diagnosis", "age", "migrant", "ethnicity", "cross cultural". We narrowed neither the period of time not selected the articles by their method, as our objective was to collect the entirety of the articles written on the subject. We completed this review by including the pertinent references made in the articles. RESULTS Twenty articles were included, all epidemiological and observational, about children diagnosed in specialized centers. Published between 2002 and 2019, they cover a 20-year research period, between 1992 and 2016. The methods are disparate: the diagnosis criteria used are from DSM IV, IV TR and ICD; data originate from medical records, phone or internet surveys, and Medicaid healthcare claims. Comparison of the age at diagnosis is the principal objective for only thirteen studies; statistical data analyses vary, especially concerning adjustments. Seventy-five percent of the articles originate from North America where the compared populations are defined by ethnic and racial categories that are not used in some other countries, notably in Europe. Only five explore the link between migratory status and age at diagnosis. The research results concerning the impact of ethnicity are contradictory, while those concerning migratory status seem to indicate that migrant children are likely to be diagnosed later. But the articles and their methods being too heterogeneous, it was difficult to make a meta-analysis and impossible to reach a scientific conclusion. CONCLUSION Nevertheless, this review highlights the existence of a lot of confounding factors and raises many issues. It shows that the United States produces most of the studies whose conclusions cannot be generalized because of the particular history and organization of this country. In Europe, where belonging to minority groups is thought to be through migratory status, studies are rare. There is an urgent need for new research in order to clarify the connection between migratory status and socioeconomic factors, to precisely define the independent variables influencing diagnosis -such as access to healthcare- and finally to explore the possibility of different symptomatic expressions depending on cultural backgrounds. This review falls within studies currently carried out by the psychiatric service at Avicenne hospital in Bobigny, France about ASD in a transcultural context.

Abstract
BACKGROUND Oligoarticular juvenile idiopathic arthritis (oligoJIA) is the most commonly diagnosed category of chronic arthritis in children. Nevertheless, there are no evidence- based guidelines for its treatment, in particular for the use of methotrexate (MTX). The primary objective of this analysis is to evaluate the outcomes in patients with persistent oligoJIA compared to those with extended oligoJIA and rheumatoid factor (RF) negative polyarthritis treated with methotrexate. METHODS Patients with persistent or extended oligoJIA or RF negative PA recorded in the Biologics in Pediatric Rheumatology Registry (BiKeR), receiving methotrexate for the first time were included in the analyses. Efficacy was determined using the Juvenile Arthritis Disease Activity Score 10 (JADAS 10). Safety assessment included the documentation of adverse and serious adverse events. RESULTS From 2005 through 2011, 1056 patients were included: 370 patients with persistent oligoJIA, 221 patients with extended oligoJIA and 467 patients with RF negative PA. Therapeutic efficacy was observed following the start of methotrexate. Over a period of 24 months JADAS-minimal disease activity (JADAS ≤2) was reached in 44% of patients with persistent oligoJIA, 38% with extended oligoJIA, 46% with RF negative PA, JADAS-remission defined as JADAS ≤1 was reached in 33% of patients with persistent oligoJIA, 29% with extended oligoJIA and 35% (RF negative PA). Patients with extended oligoJIA achieved JADAS remission significantly later and received additional biologic disease-modifying drugs significantly more often than patients with persistent oligoJIA or RF negative PA (p < 0.001). Tolerability was comparable. New onset uveitis occurred in 0.3 to 2.2 per 100 patient years. CONCLUSIONS Patients with persistent oligoJIA taking methotrexate are at least as likely to enter remission as patients with extended oligo JIA or polyarticular JIA. Patients with extended oligoJIA achieved JADAS remission significantly later. Within 2 years, almost half of the patients with persistent oligoJIA achieved JADAS-minimal disease activity.

Background
Elevated left ventricular (LV) filling pressure is an important diagnostic feature of heart failure.
Objectives
To investigate determinants of left atrial (LA) reservoir and pump strain and if these parameters may serve as markers of LV filling pressure.
Methods
In a multicenter study of 322 patients with cardiovascular disease of different etiologies, LA strain by speckle tracking echocardiography was compared to conventional echocardiographic markers using invasive pressure as reference.
Results
Left ventricular filling pressure correlated well with LA reservoir and pump strain (r-values
‑0.52 and ‑0.57, respectively) (Figure). However, LV global longitudinal strain (GLS) was the strongest determinant of LA reservoir strain (r = 0.64), and correlated well with LA pump strain (r = 0.51). For both LA strains, association with filling pressure was strongest in patients with reduced LV ejection fraction. In patients with normal GLS (≥18%), atrial strains provided no information regarding filling pressure (Figure). Reservoir strain <18% and pump strain <8% predicted elevated LV filling pressure better (p < 0.05) than the conventional indices LA volume, ratio of mitral early filling velocity/annular velocity and tricuspid regurgitation velocity. Accuracy to classify filling pressure as normal or elevated was 75% for both LA strains . When any one of the conventional indices were missing, and were replaced by LA strains, the combination of indices had accuracy 82% to correctly classify filling pressure.
Conclusions
Left atrial reservoir and pump strain may serve as clinical markers of LV filling pressure, but will be useful predominantly in patients with reduced systolic function. Due to limited diagnostic accuracy, LA strain should be used in combination with other indices.

Abstract
OBJECTIVES The objective of the study is the identification of racial differences in characteristics and comorbidities in patients hospitalized for COVID-19 and the impact on outcomes. STUDY DESIGN The study design is a retrospective observational study. METHODS Data for all patients admitted to seven community hospitals in Michigan, United States, with polymerase chain reaction confirmed diagnosis of COVID-19 from March 10 to April 15, 2020 were analyzed. The primary outcomes of racial disparity in inpatient mortality and intubation were analyzed using descriptive statistics and multivariate regression models. RESULTS The study included 336 Black and 408 White patients. Black patients were younger (62.9 ± 15.0 years vs 71.8 ± 16.4, P < .001), had a higher mean body mass index (32.4 ± 8.6 kg/m2 vs 28.8 ± 7.5, P < .001), had higher prevalence of diabetes (136/336 vs 130/408, P = .02), and presented later (6.6 ± 5.3 days after symptom onset vs. 5.4 ± 5.4, P = .006) compared with White patients. Younger Black patients had a higher prevalence of obesity (age <65 years, 69.9%) than older Black patients (age >65 years, 39.2%) and younger White patients (age < 65, 55.1%). Intubation did not reach statistical significance for racial difference (Black patients 61/335 vs. 54/406, P = .08). Mortality was not higher in Black patients (65/335 vs. 142/406 in White patients, odds ratio 0.61, 95% confidence interval: 0.37 to 0.99, 2-sided P = .05) in multivariate analysis, accounting for other risk factors associated with mortality. CONCLUSIONS Higher prevalence of obesity and diabetes in young Black populations may be the critical factor driving disproportionate COVID-19 hospitalizations in Black populations. Hospitalized Black patients do not have worse outcomes compared with White patients.

Abstract
INTRODUCTION As the population ages, loss of autonomy is becoming a priority public health issue. "Atout Age Mobility" prevention interventions for seniors aim to limit frailty, which is a predictive and reversible factor in the loss of autonomy and disability. OBJECTIVES The objective of this study is to describe the impact of these interventions on the physical performance and quality of life of a pilot sample of participants. DESIGN We conducted a prospective study named 5P PILOT with 3 months of follow up. SETTINGS Subjects were recruited by convenience sampling from participants in the "Atout Age Mobility" workshops at Saint Joseph from 04/09/2017 to 29/01/2019. PARTICIPANTS Retired people over 55 years old with no contraindications to physical activity recruited from participants in the "Atout Age Mobility" workshops in Saint Joseph. Intervention(s) (for clinical trials) or Exposure(s) (for observational studies): All participants completed 12 weeks of physical exercise called the "Atout Age Mobility" workshop, which lasted 60 minutes each week and was supervised by physical activity coaches. Main Outcome(s) and Measure(s): Physical performance was assessed by Short physical performance battery (SPPB), 10-m gait speed and grip strength measurement. Quality of life through the SF-36 test. RESULTS Ninety-six patients were included and 55 (57.3%) completed the study. There was a significant improvement in gait speed (1.35±0.26m/s vs. 1.27±0.24m/s; p=0.008). There was no significant change in SF-36, grip strength dominant arm and SPPB at the 0.01 significance level. CONCLUSION The "Atout Ages Mobility" workshops seem to significantly improve gait speed but not other aspects of physical performance or quality of life.

Abstract
BACKGROUND Rheumatic diseases have many hematological manifestations. Blood dyscrasias and other hematological abnormalities are sometimes the first sign of rheumatic disease. In addition, novel antirheumatic biological agents may cause cytopenias. SUMMARY The aim of this review was to discuss cytopenias caused by systemic lupus erythematosus and antirheumatic drugs, Felty's syndrome in rheumatoid arthritis, and autoimmune hemolytic anemia, thrombosis, and thrombotic microangiopathies related to rheumatological conditions such as catastrophic antiphospholipid syndrome and scleroderma renal crisis. Key Message: The differential diagnosis of various hematological disorders should include rheumatic autoimmune diseases among other causes of blood cell and hemostasis abnormalities. It is crucial that hematologists be aware of these presentations so that they are diagnosed and treated in a timely manner.

Abstract
Background: The IL-1 receptor-antagonist anakinra is recommended for the treatment of systemic juvenile idiopathic arthritis (sJIA) and was recently approved for first-line treatment. Long-term data from clinical practise are scarce. Methods: SJIA patients from the German biologics in pediatric rheumatology (BIKER) registry starting anakinra were grouped into two cohorts: Patients in the first-line cohort received no prior sJIA treatment except NSAID and a maximum of 3 days of steroids. Second-line cohort patients were pre-treated with steroids; DMARDs or biologics. Patient characteristics, disease-activity parameters, efficacy, and safety-parameters were compared. Results: Until December 2018, 51 anakinra patients were documented, representing 117.96 patient-years. Mean disease duration was 3.5 (± 3.8) years. At baseline, all anakinra first-line users had active systemic disease compared to 82% in the second-line users. Significant JADAS-10 improvement at last follow-up was observed in both cohorts (p = 0.02, p = 0.0014). Substantial numbers of patients in both groups reached JADAS-MDA/JADAS-remission/inactive disease (66.7%50%50% in first-liners and 60%45%70% in second-liners). Rates of serious adverse events were comparable and consistent with the overall AE profile of anakinra in patients. Conclusion: This analysis adds to the established safety profile of anakinra and demonstrates that anakinra is effective as first-line or second-line treatment.

Abstract
Abstract
Background/Introduction
Infective endocarditis (IE) remains a serious illness that is associated with remarkable morbidity and mortality in the United States (US). There are limited studies that investigated predictors of 30-day readmission risk in this population.
Purpose
We aimed to perform a contemporary analysis to investigate predictors of 30-day readmission in IE patients in the US.
Methods
We used the 2017 national readmission database to identify index admissions among adults (age ≥18) with the diagnosis of IE. Appropriate International Statistical Classification (ICD-10) codes were used to identify patients with IE. Primary outcome of interest was 30-day readmission, and hospital cost was the secondary outcome.
Results
Out of 49,692 admissions for IE, 5,743 (11.6%) patients were readmitted within 30 days. Patients who had 30-day readmission were younger (55±20 vs 61±19 years, P<0.001), 44.8% were females (P=0.08), 27.9% had diabetes mellitus (DM), 56.8% had hypertension, 37.9% had heart failure (HF), 31.3% had chronic kidney disease (CKD), 12.2% had end stage renal disease, and 47.8% had Medicare insurance. Patients who had readmissions within 30 days were more likely to have non-elective index admission (96.9% vs 93.4%, P<0.001), more likely to have hepatitis C (19.5% vs 12.2%, P<0.001), human immunodeficiency virus (HIV) (1.7% vs 1.2%, P<0.001), substance abuse (8.6% vs 5.4%, P<0.001), opioid abuse (24% vs 14.7%, P<0.001), and cocaine use (7.4% vs 4.3%, P<0.001). Overall, 5,393 (10.9%) patients died during index admission. Median cost for readmissions within 30 days was $83,217 [$41,457-$165,487], compared to the index admission cost of $90,257 [$41,945- $208,851] (P<0.001). After adjusting for age, DM, HF, and CKD, substance abuse (odds ratio (OR): 1.19 [1.07–1.33]; P 0.001), opioid abuse (OR: 1.37, [1.26- 1.48]; P<0.001), cocaine use (OR: 1.33 [1.18- 1.48]; P<0.001), HIV (OR: 1.25 [1.01–1.56]; P=0.04), and hepatitis C (OR: 1.34 [1.24–1.45]; P<0.001) correlated with higher odds of readmissions within 30 days (Figure 1).
Conclusion
Approximately 1 in 4 patients admitted for IE in the US had a history of opioid abuse and almost one fifth had hepatitis C. The 30-day readmission rate remains significant in IE with high financial burden on the health system. Both opioid abuse and hepatitis C were among the highest predictors of readmission within 30 days. Identifying modifiable predictors of readmission in this population may reduce readmission risk and healthcare cost.

Abstract
Abstract
Background
In recent years, there has been increasing recognition of a potentially-reversible, transient/ subacute form of constrictive pericarditis (CP). To date, studies have been small with lack of long-term longitudinal follow-up.
Purpose
We aimed to elucidate the causes and natural history of subacute CP.
Methods
Patients were included if (1) they had a diagnosis of CP, (2) had cardiac magnetic resonance (CMR) within 12 months of symptom onset with evidence of pericardial delayed enhancement/ inflammation (Figure) (3) received anti-inflammatory medications.
Results
A total of 78 individuals were included, comprising 61 men (78%) with a mean age of 59±14 years. Causes of subacute CP included idiopathic/ viral pericarditis (58%), post-pericardiotomy (29%), autoimmune (6%), radiation therapy (3%) and others (4%). After median follow-up of 4.4 years, 31 (40%) required pericardiectomy. There were no deaths.
Patients who underwent pericardiectomy had longer duration of symptoms at presentation [6 (4–9) vs. 3 (2–5) months, P<0.01], were more likely to be on diuretic therapy (87 vs. 45%, P<0.001), had lower ultra-sensitive C-reactive protein [4.4 (2.6–13.1) vs. 11.95 (1.8–61.55) mg/dl, P<0.001] and lower erythrocyte sedimentation rate [5 (2–10) vs. 25 (6–43 mm/hr), P=0.031] compared to those who were managed medically. There were no other significant differences in clinical characteristics or baseline anti-inflammatory therapy. The presence of elevated inflammatory markers (HR: 0.18; 95% CI: 0.06–0.58, P<0.01) was an independent predictor of freedom from pericardiectomy after adjustment for relevant clinical and imaging parameters.
Conclusions
We present the original observations of the largest cohort of patients with transient CP to date and demonstrate that increased inflammatory markers were independently associated with long-term freedom from pericardiectomy. Our results suggest that a trial of anti-inflammatory therapy in the setting of elevated inflammatory markers may be appropriate prior to referral for surgery given the possible reversibility.

Abstract
Background Coronavirus disease 2019 (COVID-19), a disease caused by the new coronavirus (SARS-CoV-2), is a particular threat to old people. At the end of March 2020, the first and so far largest outbreak of the disease occurred in a retirement home in Hamburg. Methods Analysis of procedures in dealing with a residential unit affected by SARS-CoV‑2, accommodating a risk group of 60 seniors with dementia is presented as well as a detailed presentation of post-mortem examination results of all 8 deceased tested positive for SARS-CoV‑2. Results Out of 60 residents, 39 were infected by SARS-CoV‑2. Due to preventive procedures it was possible to stop further spreading of the infection to other residential areas. In all 8 fatal cases, the autopsy diagnosis was death due to COVID-19. Autopsies revealed all COVID-19 patients to have a fatal (broncho)pneumonia and signs of relevant pre-existing cardiac, renal and pulmonary conditions in all cases. In 75% (n = 6) of the cases a fresh venous thrombosis was found. In 66.7% (n = 4) of the cases thrombotic events were combined with peripheral pulmonary artery thromboembolisms. Conclusion The cohort of SARS-CoV‑2 infected residents of a nursing home is characteristic for clinical and epidemiological features of the new coronavirus disease. Due to a centralized evaluation of all fatalities at the Institute of Legal Medicine in Hamburg, a detailed examination of all deceased positive for SARS-CoV‑2 was possible. Thereby, increased case fatality rates of approximately 20% could in all cases be assigned to a relevant number of pre-existing comorbidities of multiple organ systems, which was consistent with the clinical data available.

Abstract
Establishing new animal models for the study of inflammation is very important in the process of discovering new drugs, since the inflammatory event is the basis of many pathological processes. Whereas rodent models have been the primary focus of inflammation research, we defend the zebrafish (Danio rerio) test as a feasible alternative for preclinical studies. Moreover, despite all the technological development already achieved by humanity, nature can still be considered a relevant source of new medicines. In this context, the aim of this work was to evaluate the anti-inflammatory effect of a substance isolated from the medicinal plant Annona crassilfora Mart, the peltatoside, in an inflammatory model of zebrafish. It was determined: (i) total leukocyte count in the coelomate exudate; (ii) N-acetyl-β-d-glucuronidase (NAG); (iii) myeloperoxidase (MPO); (iv) and the histology of liver, intestine and mesentery. Peltotoside (25, 50 and 100 μg) and dexamethasone (25 μg) were administered intracelomatically (i.c.) 30 min before carrageenan (i.c.). Pretreatment with peltatoside at three doses significantly inhibited leukocyte recruitment in the coelomic cavity, and inhibited NAG and MPO activity against the action of Cg, in a similar manner as dexamethasone. However, some microlesions in the evaluated organs were detected. The dose of 25 μg showed an anti-inflammatory effect with lower undesirable effects in the tissues. Our results suggest that the zebrafish test was satisfactory in performing our analyzes and that the peltotoside has a modulatory action in reducing leukocyte migration.

Abstract
Background:Golimumab (GOL) is approved for treatment of polyarticular juvenile idiopathic arthritis (pJIA) in patients 2 years and older. Data on long-term safety in this indication are limited.Objectives:Prospective monitoring of long-term safety and effectiveness of GOL in routine care using the German BIKER registry.Methods:In this non-interventional study baseline and safety parameters were compared between patients initiating GOL and contemporary matched control cohorts starting either an alternative TNF inhibitor (TNFi) or methotrexate (MTX) without exposure to a biologic. Efficacy outcomes were JADAS10, JIA ACR scores, joint counts and Childhood Health Assessment Questionnaire disability-index (CHAQ-DI). Safety assessments were based on adverse event (AE) reports.Results:From 2016 to 2019, 55 patients initiating GOL have been recruited and matched to 110 patients starting alternative TNFi and 47 biologic-naïve patients. Patients starting GOL had a longer disease duration (6.8y vs. 4.1 y and 1.0y; p<0.0001) and use of GOL was significantly more often second-line (85% vs 31% and 0%, p<0.0001). Disease activity was lower at baseline compared to MTX patients as indicated by active joint counts, JADAS10 and concomitant steroid use. Otherwise they were comparable with patients treated with other TNFi (Table 1).Table 1Comparison of GOL cohort with (1) other TNFi cohort and (2) MTX cohort.GOLN=55Other TNFiN=110MTXN=47p-value #GOL vs TNFi/MTXGender female, n (%)44 (80)86 (78)34 (72)0.8/0.5Age at baseline, mean (SD), years13.6 (2.8)13.6 (3.0)13.1 (3.4)1.0/0.4Disease duration, mean (SD), years6.8 (4.5)4.1 (3.8)1.0 (1.6)<0.0001RF neg. polyarthritis, n (%)28 (51)53 (48)29 (62)0.7/0.3RF pos. polyarthritis, n (%)6 (11)18 (16.4)11 (23.4)0.5/0.1Extended oligoarthritis, n (%)20 (36.4)37 (33.6)6 (12.8)0.7/0.007Psoriatic arthritis1 (1.8)2 (1.8)1 (2.1)1.0/1.0Pretreatment bDMARD n(%)47 (85.5)34 (30.9)0<0.0001Concomitant steroids, n (%)9 (16.4)26 (23.6)25 (53.2)0.3/0.0001Active joint count, mean (SD)4.6 (4.0)5.4 (6.1)9.7 (6.5)0.4/<0.0001CHAQ DI, mean (SD)0.4 (0.4)0.5 (0.6)0.6 (0.7)0.3/0.07ESR, mm/h, mean (SD)20.4 (27.6)15.4 (18.6)21.4 (18.6)0.2/0.8JADAS10, mean (SD)11.3 (6.0)12.4 (5.8)16.9 (5.4)0.3/<0.0001AE, n (rate/100PY; 95%CI)45 (96; 72-128)106 (114; 94-138)39 (107; 78-146)0.3/0.6SAE, n (rate/100PY; 95%CI)2 (4.2; 1.1-17)5 (5.4; 2-13)1 (2.7; 0.4-19)0.8/0.7Infectious AE, n (rate/100PY; 95%CI)6 (12.8; 5.7-28)11 (11.8; 6.5-21)9 (24.5; 13-47)0.9/0.2Serious infections, n (rate/100PY; 95%CI)02 (2.2; 0.5-8.6)0n.a.Uveitis new manifestation1 (2.1; 0.3-15)2 (2.2; 0.5-8.6)01.0/n.a.In GOL treated patients a marked clinical response was noted at 6 months and beyond demonstrated by a significant decrease of the mean JADAS 10 from 11.3 to 6.4 (p=0.0008), as well as JIA ACR 30/50/70/90 response rates of 56/56/35/21%. JADAS remission and minimal disease activity was observed in 18% and 47% after 6 months and in 29% and 43% of patients after 12 months.Rates of AE, SAE and infectious AE were comparable between the GOL cohort (96, 4.2 and 12.8/100PY), the alternative TNFi cohort (114, 5.4 and 11.8/100PY) and the MTX cohort (107, 2.7 and 24.5/100PY). SAE reported in the GOL cohort were uveitis and JIA flare (each 1). Two serious infections, both influenza, were reported in the alternative TNFi cohort, none in the GOL cohort. No case of pregnancy, malignancy or death was reported.Conclusion:Interim results from this ongoing safety surveillance study indicate acceptable safety and tolerability of GOL in pJIA that is comparable to treatment with alternative TNFi or MTX. The long-term effectiveness data reinforce the established efficacy of GOL in pJIA treatment.Disclosure of Interests:Gerd Horneff Grant/research support from: AbbVie, Chugai, Merck Sharp & Dohme, Novartis, Pfizer, Roche, Speakers bureau: AbbVie, Bayer, Chugai, Merck Sharp & Dohme, Novartis, Pfizer, Roche, Angela Zimmer: None declared, Kirsten Minden Consultant of: GlaxoSmithKline, Sanofi, Speakers bureau: Roche, Toni Hospach: None declared, Frank Weller-Heinemann: None declared, Sandra Hansmann Consultant of: Advisory board Novartis Pharma, Jasmin Kuemmerle-Deschner Grant/research support from: Novartis, Sobi, Consultant of: Novartis, Sobi, Speakers bureau: Novartis, Sobi, Maria Fasshauer Consultant of: Shire, CSL Behring, Nadja Hofmann: None declared, Hans Koessel: None declared, Ivan Foeldvari Consultant of: Novartis, Sonja Mrusek: None declared, Daniel Windschall Speakers bureau: Abbvie, Nils Onken: None declared, Markus Hufnagel: None declared, Dirk Foell Grant/research support from: Novartis, Sobi, Pfizer, Speakers bureau: Novartis, Sobi, Normi Brueck: None declared, Prasad Oommen Consultant of: Novartis, Frank Dressler: None declared, Astrid Helling-Bakki: None declared, Ariane Klein Consultant of: Celgene

Abstract
Background:Tocilizumab (TOC) is approved for treatment of polyarticular juvenile idiopathic arthritis (pJIA). Data out of clinical practice are limited.Objectives:Long-term surveillance of patients initiating TOC treatment compared to a cohort of patients initiating a comparator biologic using the BIKER-registry.Methods:Baseline parameters, efficacy and safety parameters were compared. Efficacy outcomes were JADAS10 and joint counts. Functional status was determined with the Childhood Health Assessment Questionnaire disability-index (CHAQ-DI). Safety was assessed by adverse events (AE) reports.Results:Until January 2020, 152 patients have been recruited to each cohort. Patients starting on TOC were older at treatment start (12.1 vs. 10.1 years (y); p<0.0001) and had a longer disease duration (5.4y vs. 3.0y; p<0.0001). TOC was significantly more often a second-line biologic (84% vs 13%, p< 0.0001).

There were no significant differences between patients from the TOC cohort and their matched controls regarding JIA ACR 30/50/70/90 criteria and active joint counts. JADAS 10, JADAS remission (REM) and minimal disease activity (MDA) was reached by comparable numbers in the TOC (37% and 58%) and the control cohort (37% and 60%).While the total number of AE was comparable between the TOC cohort (58/100PY) and in the control cohort (54/100PY; RR 1.1; 95%CI 0.9-1.4), more serious AE (SAE) were reported with TOC (4.8/100PY compared to 1.4/100PY; RR 3.5; 95% CI 1-10.9). Medically important infections and uveitis events were documented at significantly lower frequency in the TOC- (0.8/100PY) than in the control cohort (4.1/100PY; RR 0.2; 95% CI 0.04-0.9). SAE with TOC were suicidal intent (n=3), depression (n=2), exacerbation of JIA, abscess, gastrointestinal infection, abdominal pain, colitis, bone surgery and fracture (n=1). SAE in the control cohort were depression, osteomyelitis, gastrointestinal infection and superinfected eczema (n=1). No significant differences regarding cytopenia and elevated transaminases were observed. No gastrointestinal perforation, no vascular event, no malignancy and no death occurred.Conclusion:The efficacy of tocilizumab is comparable to that of alternative biologics. Tolerability was acceptable. As Tocilizumab was given as a second-line biologic in the vast majority of patients, comparisons between the cohorts have to be interpreted carefully.

Abstract
Background:Although efficacy of Tumor necrosis factor inhibitors (TNFi) for treatment of psoriasis is well established, patients may develop psoriasis for the first time while on TNFi as a paradoxical effect. Few data are available in patients with juvenile idiopathic arthritis (JIA).Objectives:To analyze the incidence of psoriasis in TNFi – treated JIA patients and to identify associated factors.Methods:Safety data from patients registered in the German Biologics registry (BIKeR) were analyzed. Cohorts of patients were grouped by treatment: any or multiple TNFi, single TNFi, biologics other than TNFi and no biologics (control group on methotrexate (MTX) only). TNFi-associated psoriasis was defined as incident diagnosis of psoriasis after starting a TNFi. Patients with personal history of psoriasis prior to TNFi therapy were excluded. Rates and events per 100 patient-years (PY) of exposure were calculated using AEs reported after first dose under therapy and under the age of 18 years. Rates were compared by X2-test, event rates by Wald test.Results:A total of 4149 treatment episodes with TNFi (Etanercept, Adalimumab, Golimumab, Infliximab), with a total exposure time of 8437 PY, were identified. There were 676 treatments with a non-TNFi- biologic (Tocilizumab, Abatacept, Anakinra, Canakinumab) with a total exposure time of 1112 PY. MTX monotherapy was conducted in 1692 patients with a total exposure time of 3971 PY. In total, 31 patients were diagnosed with incident psoriasis on JIA-treatment (Table 1). The mean duration of therapy until incident psoriasis was 2.2 (± 1.8) years. Multiple psoriatic skin manifestations were observed.Psoriasis events were significantly more frequent in any or multiple TNFi compared to MTX-monotherapy, and specifically in the subgroup of TNF-antibody treatment (all) or Adalimumab compared to MTX or Etanercept (Table 2). Interestingly, psoriasis events were also observed with non-TNFi at high frequency. At occurrence of the event, patients exposed to biologics received MTX or steroids less frequently compared to the total patient cohort and had a higher JADAS10.Table 1.N/PYTotalCohort*4792/13519All TNFi4149/8437ADA1105/1859ETA2824/6307GOL144/145INF76/126Non-TNFi676/1112MTX only1692/3971Psoriasis events/rate(%)31/0.623/0.613/1.27/0.22/1.41/1.37/0.61/0.1Pso**/100 PY (95%CI)0.2(0.2-0.3)0.3(0.2-0.4)0.7(0.4-1.2)0.1(0.1-0.2)1.4(0.3-5.5)0.8(0.1-5.6)1.0(0.5-2.1)0.03(0.004-0.2)Age at eventMean ± SD13.9(±3.1)13.9(± 3.2)14.0(±3.0)13.0(±4.0)15.1(±3.4)16.413.4(±3.1)17.3Female24(77%)18(78%)10(77%)5(71%)2(100%)1(100%)5(71%)1(100%)ANA positive22(71%)16(70%)10(77%)4(57%)1(50%)1(100%)5(71)1(100%)Treatment duration until event (years) Mean ±SD2.2±1.82.4±2.32.2±1.42.8±2.20.6±0.53.81.4±2.05.6ConcomitantMTX11(36%)6(26%)3(23%)2(29%)1(50%)04(57%)1(100%)ConcomitantSteroids4(13%)2(9%)01(14%)01(100%)2(29%)0JADAS10 Median [IQR]***2.5(0.6-8.8)4.2(1.0-11.0)2.0(0.6-10.1)5.8(1.5-11.4)18.06.61.3(0.8-3.4)1.7*individual therapy numbers add to a sum > the total cohort number, because some patients switched between multiple drugs; ** Pso= Psoriasis event; *** at time of eventTable 2.ReferencePsoriasis eventn/100 PYComparatorPsoriasis eventn/100 PYRisk ratioP-valueNon-TNFi0.63TNFi0.270.4 (0.2 -1.0)0.052MTX0.03TNFi0.2710.8 (1.5-80.1)0.019MTX0.03ETA0.114.4 (0.5-35.8)0.165MTX0.03TNF-antibodies0.7542.9 (5.8-317)0.0002ETA0.11TNF-antibodies0.756.8 (2.8-16.5)0.00002MTX0.03ADA0.6927.4 (3.6-2209)0.001Non-TNFi0.63ADA0.691.1 (0.4-2.7)0.847Non-TNFi0.63ETA0.110.2(0.1-0.5)0.0012ETA0.11ADA0.696.2 (0.5-15.6)0.0001Conclusion:Our findings demonstrate a higher incidence of psoriasis in monoclonal-antibody-TNFi-treated JIA-patients, whereas in Etanercept-treated JIA patients no significant increase was detected.

Abstract
Background:Systemic lupus erythematosus (SLE) is a clinically heterogeneous disease, which begins in childhood and adolescence in 15 - 20% of cases. Since 2004, data on SLE have been collected by means of a disease-specific questionnaire as part of the National pediatric rheumatology database (NPRD) in Germany. Since 2014, kidney biopsy results have been recorded to further specify kidney involvement.Objectives:Evaluation of clinical signs and symptoms, outcome and laboratory data of patients with juvenile systemic lupus erythematosus from a large database in Germany.Methods:Data from patients with SLE recorded in the NPRD in 2017 were considered for the analysis. In addition to age, sex, onset of disease, the criteria that led to the diagnosis, various laboratory parameters, organ involvement (current, ever) and therapy (current, last 12 months), current disease activity (numerical rating scale 0-10, NRS) and ECLAM (score 0-10) were recorded. Patient-reported outcomes included global assessments of overall-wellbeing and fatigue (NRS 0-10) and functional ability (CHAQ).Results:196 patients (86% female) with a median age of 16 years were documented. Criteria most frequently met at diagnosis included “antinuclear antibodies” (88%), followed by “anti-ds-DNA-Ab” (66%), “butterfly erythema” (42%) and “arthritis” (41%). A positive family history was found in 10% of patients.At documentation, 85% of patients received disease-modifying anti-rheumatic drugs, most frequently hydroxychloroquine (73%), followed by mycophenolate mofetil (32%) and azathioprine (17%). Systemic glucocorticoids obtained 52% of patients, 12% ≥ 0.2 mg/kg/day. Biologics (rituximab 2%) and cyclophosphamide i.v. (3%) were rarely administered during the last 12 months. Disease activity was reported as 1.0 (NRS, median, IQR 0 - 9), ECLAM as 1.0 (median, range 0 - 10). In the laboratory, leukopenia < 3500/µl was found in 9% of patients, lymphopenia < 1500/µl in 47% and erythrocyte sedimentation rate (ESR) > 25 mm in 15% of patients. Mean CHAQ was 0.24, and 86% of patients had a CHAQ score < 0.5. Mean patient`s global assessment of overall-wellbeing was 1.5, while the mean fatigue score was 2.86 (18% NRS score 7-10).The following organ involvement was ever present: general symptoms 84%, skin/mucosa 72%, joints 73%, thyroid 15%, muscle 25%, lungs 17% and CNS 30%. In 45/190 (24%) patients, a kidney involvement was stated. In 34 patients (75%) a kidney biopsy was performed and histology yielded the following results: Class 1: 6.7%, Class 2: 16.7%, Class 3: 40.0%, Class 4: 23.3%, Class 5: 13.3%.Conclusion:The most common clinical symptoms documented in juvenile SLE patients were skin and joint involvement. In the course of the disease, a quarter of the patients developed kidney involvement, mostly proliferative nephritis. Apparently, azathioprine is increasingly being replaced by mycophenolate mofetil, biologicals have hardly been used so far. Although functional outcome and overall-wellbeing of jSLE patients was good, fatigue was a concern for some patients.Disclosure of Interests:Claudia Sengler: None declared, Martina Niewerth: None declared, Nils Geisemeyer: None declared, Hermann Girschick: None declared, Ariane Klein Consultant of: Celgene, Annette Friederike Jansson: None declared, Markus Hufnagel: None declared, Kirsten Minden Consultant of: GlaxoSmithKline, Sanofi, Speakers bureau: Roche
