The implementation and utility of clinical exome sequencing in a South African infant cohort

Genetic disorders are significant contributors to infant hospitalization and mortality globally. The early diagnosis of these conditions in infants remains a considerable challenge. Clinical exome sequencing (CES) has shown to be a successful tool for the early diagnosis of genetic conditions, however, its utility in African infant populations has not been investigated. The impact of the under-representation of African genomic data, the cost of testing, and genomic workforce shortages, need to be investigated and evidence-based implementation strategies accounting for locally available genetics expertise and diagnostic infrastructure need to be developed. We evaluated the diagnostic utility of singleton CES in a cohort of 32 ill, South African infants from two State hospitals in Johannesburg, South Africa. We analysed the data using a series of filtering approaches, including a curated virtual gene panel consisting of genes implicated in neonatal-and early childhood-onset conditions and genes with known founder and common variants in African populations. We reported a diagnostic yield of 22% and identified seven pathogenic variants in the NPHS1, COL2A1, OCRL, SHOC2, TPRV4, MTM1 and STAC3 genes. This study demonstrates the utility value of CES in the South African State healthcare setting, providing a diagnosis to patients who would otherwise not receive one and allowing for directed management. We anticipate an increase in the diagnostic yield of our workflow with further refinement of the study inclusion criteria. This study highlights important considerations for the implementation of genomic medicine in under-resourced settings and in under-represented African populations where variant interpretation remains a challenge.

Effects of breed, age and gender on equine platelet rich plasma and correlation of platelet count with its physical aspect

ABSTRACT Platelet rich plasma samples from 50 healthy horses of five different breeds (Thoroughbreds - TB, Brazilian Criollo Horses - BCH, Brazilian Sport Horses - BSH, Miniature Horses - MH and Crossbred Horses - CB), were investigated as to breed, age, and gender effect for platelet concentration. Moreover, a score for physical analysis was established to correlate PRP physical aspect with platelet count. Platelet count was performed by an automatic hematology analyzer and by manual count. PRP physical analysis was based on color, aspect, and capacity to separate blood components. MH showed significant higher platelet concentration than BSH (p<0.05), while the other breed comparisons showed no significant difference. There was no significant difference for gender but there was a weak correlation of age with PRP platelet concentrations (rs = -0.24). Most of the PRP presented yellow color, the separation of blood components showed no correlation, but the aspect showed a moderate correlation (rs = 0.30) with platelet count. Results suggest that PRP platelet concentration can be influenced by intrinsic factors such as breed. Additionally, the analysis of PRP aspect can help to evaluate the quality of the product when there is no access to platelet counts.

[Further development of regional early care-Many roads lead to Rome : Developmental stages of four established rheumatological early care concepts in different regions of Germany]

In order to shorten the prognostically relevant waiting time until diagnosis and initiation of appropriate treatment in inflammatory rheumatic diseases, rheumatological centers in many regions across Germany have established and continuously developed specific early care concepts. Evaluated models from Altötting·Burghausen, Berlin Buch, Düsseldorf and Heidelberg and their developmental stages as a response to internal and external challenges are presented in this overview. The transparent publication of the developmental steps and the exchange of experiences aim at promoting new early care concepts in other regions and continuing the joint dialogue for improvement of the early detection and quality of care of inflammatory rheumatic diseases in Germany.

POS1246 COVID-19 IN RITUXIMAB TREATED PATIENTS WITH INFLAMMATORY RHEUMATIC DISEASES

Background

At the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease 2019 (COVID-19) pandemic, the influence of anti-inflammatory therapy on the course of SARS-CoV-2 infection in patients with inflammatory rheumatic diseases (IRD) was unknown. In the meantime, several data indicate an association of severe courses of COVID-19 with the use of rituximab (RTX).

Objectives

To gather further knowledge about SARS-CoV-2 infections in RTX-treated IRD patients, data from the German COVID-19-IRD-registry were analysed.

Methods

Hospitalisation was used as a surrogate of COVID-19 severity. Baseline characteristics, disease features, medication and outcome of COVID-19 were compared in RTX-treated inpatients and outpatients.

Results

In total, 3592 cases were reported in the registry, which included 130 RTX patients (3.6%) for our analysis. RTX-treated inpatients were older than RTX-treated outpatients (median age 63 y vs 56 y, p=0.007). Patients with granulomatosis with polyangiitis treated with RTX (n=32) showed a significant higher COVID-19 related hospitalisation rate (33% vs 11%, p=0.005), which was not the case for patients with rheumatoid arthritis (49% vs 50%). Cardiovascular comorbidities were reported more frequently in hospitalised RTX-treated patients (20% vs. 6%, p=0.032). More than 50% of the RTX-treated inpatients developed COVID-19 related complications, e.g. acute respiratory distress syndrome. The median time period between the last RTX treatment and SARS-CoV-2 infection was shorter in inpatients than in non-hospitalised patients (3 (range 0-17) vs. 4 months (range -29), p=0.039). The COVID-19 related mortality rate was 14% (n=19) in RTX-treated IRD patients. In RTX-treated inpatients and outpatients, there were no relevant differences with respect to the use of concomitant glucocorticoids or other disease modifying anti-rheumatic drugs, disease activity, median last RTX dose or median number of immunomodulatory drugs prior to RTX treatment.

Conclusion

In addition to general risk factors, such as age and comorbidities, it is already known that IRD patients treated with RTX show a higher rate of severe COVID-19. In our registry, RTX-treated patients with granulomatosis with polyangiitis appear to be at even higher risk to develop severe COVID-19 compared to other IRD. Moreover, the shorter the time since the last RTX treatment, the higher seems to be the risk of developing severe COVID-19. This might be explained by a more profound B-cell depletion in the first weeks after RTX treatment warranting further studies.

OP0306 IMPACT OF INFLAMMATION ON INTERSTITIAL LUNG DISEASE IN PATIENTS WITH RHEUMATOID ARTHRITIS - AN ANALYSIS OF THE GERMAN BIOLOGICS REGISTER RABBIT

Background

Ten percent of patients with prevalent rheumatoid arthritis (RA) develop an interstitial lung disease (ILD), which is associated with higher mortality (1). A previous study identified high/moderate disease activity, but not CRP, as a risk factor for RA-ILD (2).

Objectives

To analyse whether systemic inflammation (CRP and ESR) and/or disease activity measured with a composite score (DAS28-ESR) are associated with the occurrence of ILD in patients with RA.

Methods

Data from RA patients observed in the biologics register RABBIT until 10/2020 were included. Patients with incident ILD were selected as cases and matched 1:5 to controls using a modified risk-set sampling (controls had no ILD during the entire observation time). Matching criteria were age, sex, RA duration, date of enrolment and observation time. Odds ratios (OR) and 95% confidence intervals (CI) were computed by conditional logistic regression and adjusted for factors identified by a directed acyclic graph (DAG), namely smoking, rheumatoid factor (RF), chronic obstructive pulmonary disease, number of biologics until index date (date of ILD-diagnosis in cases, date after the respective observation time in controls) and mean glucocorticoid dosage (12 months prior index date). For the regression, CRP and ESR were log-transformed due to their skewed distribution, and missing values were addressed by multiple imputations (n=10).

Results

Out of 19,148 RA patients enrolled since 2001, 133 patients with incident ILD were identified. Half of the ILDs were diagnosed by computed tomography (n=67), 8% by x-ray (n=10) and in 42% the method was unknown (n=56).

At baseline, cases and controls had a mean age of 61 years, 68% were female, and mean RA disease duration was 9 years. Differences were observed in smoking status (59% ever smokers in cases vs. 48% in controls), RF positivity (84% vs. 72%) and the sum of comorbidities (means 3.1 vs. 2.3).

During the 12 months prior to the index date, mean values of CRP and especially of ESR were significantly higher in cases compared to controls. This difference was not observed for DAS28 (Figure 1, upper figures). Furthermore, more cases than controls were in a high inflammatory status, but not in at least moderate disease activity (Figure 1, lower figures). The adjusted regression analyses confirmed these results: CRP and ESR were significantly associated with incident ILD both at the time of diagnosis and in the 12 previous months, and results were even more pronounced with elevated CRP and ESR, which was not the case for DAS28 (Table 1).

Conclusion

In contrast to other data, our analyses found that markers of systemic inflammation, but not the DAS28 composite score, are associated with the occurrence of incident ILD in patients with RA and can be predictors for the development of RA-ILD. Therefore, in a treat-to-target approach, rheumatologists should pay particular attention to controlling systemic inflammation.

POS0446 Arp2/3 AS A Lasp1 INTERACTION PARTNER REGULATES CELL-TO-CELL CONTACT FORMATION OF FIBROBLAST-LIKE SYNOVIOCYTES IN RA

Background

In rheumatoid arthritis (RA), fibroblast-like synoviocytes (FLS) undergo a stable transformation resulting in an aggressive phenotype mediating cartilage damage by increased levels of adhesion molecules. In this context, Lasp1 and the Arp2/3 complex are of interest because they modulate actin organization and focal adhesion turnover.

Objectives

In this study, the effects of Arp2/3 on cadherin-11 mediated cell-to-cell contact formation have been investigated using the arthritic hTNFtg mouse model.

Methods

Expression levels of Lasp1 and Arp2/3 protein complex were investigated in synovial tissue of wild type (wt) and hTNFtg hind paws by immunohistochemistry. Primary FLS were analysed, respectively and co-immunoprecipitation experiments were performed. In addition, lasp1-/- mice were interbred with hTNFtg animals and offspring were evaluated for disease progression and joint destruction. To further study the role of Arp2/3 in the function of the cadherin-11 adhesion complex, the effects of an Arp2/3 inhibitor (CK666) on cell-to-cell contact formation in FLS derived from hTNFtg and lasp1-/-hTNFtg mice were investigated by stainings. To assess signaling pathway activation, cells were stimulated with the growth factor PDGF.

Results

Upregulated Lasp1 levels were found in synovial tissue and FLS of hTNFtg compared to wt mice. Assays showed that Arp2/3 is part of the adherens junction (AJ) machinery in FLS although Arp2/3 expression levels were not changed between the genotypes. In vivo evaluation of lasp1-/-hTNFtg mice revealed a milder arthritis score, less cartilage degradation and reduced FLS attachment to articular cartilage compared to hTNFtg mice. In vitro, the loss of Lasp1 led to clear alterations in AJ arrangement indicated by altered β-catenin pattern. As expected, β-catenin expression was mainly located at adhesion sites between adjacent cells. In hTNFtg FLS, these structures were characterized by a zipper-like pattern. In contrast, these structures were disrupted in lasp1-/-hTNFtg FLS. Interestingly, CK666 induced zipper-like structures in hTNFtg FLS comparable to the pattern found in lasp1-/-hTNFtg cells. Furthermore, lasp1-/-hTNFtg FLS showed decreased Src phosphorylation following PDGF stimulation in comparison to hTNFtg FLS.

Conclusion

Lasp1 represents an interesting target involved in RA-caused joint destruction, because its loss results in significantly reduced cartilage destruction and altered FLS contacts mediated by Arp2/3.

POS0809 CHARACTERIZATION OF RELAPSES IN PATIENTS WITH GIANT CELL ARTERITIS (GCA) PATIENTS- DATA FROM THE REAL-LIFE TREATMENT AND SAFETY (REATS)-GCA COHORT

Background

Giant cell arteritis (GCA) has the tendency to relapse once treatment is tapered or stopped. Such relapses represent a potential threat to GCA patients as they can lead to severe symptoms and organ damage.

Objectives

To assess the frequency and type of relapses in patients with GCA

Methods

The Real-Life Treatment and Safety (REATS)-GCA cohort has been established by extracting the data on clinical presentation, inflammatory markers, imaging, comorbidities, treatments and serious adverse events of GCA patients from 6 specialized centres in Germany. We undertook descriptive and survival analyses (Kaplan-Meier), and compared baseline characteristics of participants with vs. without relapse. Ethical approval for the cohort was obtained.

Results

We included 395 patients with a mean age of 71 years, including 264 (66.8 %) females and 129 (32.7%) males. Diagnosis of GCA was supported by temporal artery ultrasound in 37%, 18F-FDG-PET/CT in 29%, temporal artery biopsy in 14% of patients and by MRI or clinically in the remaining patients. 31% of patients presented with an isolated cranial manifestation and 18% with isolated extracranial manifestations. Most common presenting symptoms were headache (57%), fatigue (55%), weight loss (42%) and polymyalgia (38%) (Table 1). The most common comorbidities at the time of study inclusion were arterial hypertension (68%), followed by osteoporosis (26%). Within a median total follow-up duration of 22.2 (11.7-40.6) months, 97 of the 395 patients relapsed including 15 patients who relapsed more than once. The median (IQR) time to first relapse was 12.5 (7.1-21.8) months. Median relapse-free survival was 7.8 years with a relapse risk of 12% (CI, 9 to 15%) at 1 year and 38% (CI, 30 to 45%) at 5 years (Figure 1). Most common symptoms at relapse were headache (35%), polymyalgia (23%), fatigue (19%) and night sweats (12%) (Table 1). Three patients relapsed with sudden loss of vision. Among the 114 relapses observed, 94 (83%) occurred under prednisolone treatment with a median dose of 7.0 mg/day (IQR 4.0-12.5). 26 (23%) occurred under methotrexate and 14 (12%) under tocilizumab treatment. Comparing the baseline characteristics that were documented in this study, we did not find a statistically significant difference in relapsing versus non-relapsing GCA patients.

Conclusion

About one fourth of GCA patients relapsed and the overwhelming majority of relapses occurred before patients were able to stop glucocorticoids. The leading symptoms at relapse are headache and fatigue, while loss of vision is rare (0.76%). Baseline characteristics seem to be poorly informative about the risk of relapse, therefore regular monitoring of GCA patients is necessary.

OP0179 CHARACTERISTICS AND OUTCOMES OF SARS-CoV-2 BREAKTHROUGH INFECTIONS AMONG DOUBLE AND TRIPLE VACCINATED PATIENTS WITH INFLAMMATORY RHEUMATIC DISEASES

Background

SARS-CoV-2 vaccines offer the most effective way to reduce the risk of severe COVID-19. Recent data indicate sufficient immune response after vaccination in most patients with inflammatory rheumatic diseases (IRD) on immunomodulatory treatments.

Objectives

To investigate the clinical profile of SARS-CoV-2 breakthrough infections among double and triple vaccinated patients with IRD.

Methods

Data from the German COVID-19-IRD registry, collected by treating rheumatologists between February 2021 and January 2022 were analysed. Patients double or triple vaccinated against COVID-19 ≥14 days prior to proven SARS-CoV-2 infection were identified, and type of IRD, vaccine, immunomodulation, comorbidities and outcome of the infection were compared with 737 unvaccinated IRD-patients with COVID-19.

Results

In total, 271 cases of breakthrough infections were reported, 250 patients (91%) had received two doses of vaccines, 21 (9%) patients three. More than 70% of the patients received Pfizer/Biontech vaccine for the first, second and third vaccination. The median time from second/third vaccine dose to infection was 148 days (range 14-302) days. Most of the patients were diagnosed with inflammatory joint diseases (Table 1). Most of the patients were treated with methotrexate (Table 1). The use of Januskinase inhibitors(i) was more frequently reported in double vaccinated patients (10.4% vs 4.8%), whereas tumor necrosis (TNF)i were reported more often in triple vaccinated patients (33.3% vs. 22.8). Hospitalisation rate was higher in unvaccinated IRD-patients than in vaccinated ones, while fatality rate was similar in unvaccinated and double vaccinated patients. Although the rate of comorbidities and median age were higher in triple-vaccinated patients, infected patients showed a lower rate of hospitalisation, neither COVID-19 related complications, nor the need of oxygen treatment or death.

Conclusion

In this cohort of triple-vaccinated IRD patients no fatal courses and no COVID-19 related complications were reported, although median age and rate of comorbidities were higher compared to double-vaccinated and unvaccinated patients. These results support the general recommendations to reduce the risk of severe COVID-19 disease by administering three doses of vaccine, especially in patients with older age, presence of comorbidities, and on immunomodulatory treatment.

High rate of self-improving phenotypes in children with non-syndromic congenital ichthyosis: case series from south-western Germany

BACKGROUND

Non-syndromic congenital ichthyosis describes a heterogeneous group of hereditary skin disorders associated with erythroderma and scaling at birth. Although both severe and mild courses are known, the prediction of the natural history in clinical practice may be challenging.

OBJECTIVES

To determine clinical course and genotype-phenotype correlations in children affected by non-syndromic congenital ichthyosis in a case series from south-western Germany.

METHODS

We performed a retrospective observational study of 32 children affected by non-syndromic congenital ichthyoses seen in our genodermatosis clinic between 2011 and 2020. Follow-ups included assessment of weight and severity of skin involvement utilizing a modified Ichthyosis Area Severity Index (mIASI). mIASI was calculated as a sum comprising the previously published IASI score and an additional novel score to evaluate palmoplantar involvement. Linear regression was assessed using Pearson correlation, and statistical analysis was performed using the Wilcoxon-Mann-Whitney test.

RESULTS

This study included 23 patients with autosomal recessive congenital ichthyosis, seven with keratinopathic ichthyosis and two with harlequin ichthyosis. Cutaneous manifestations improved in more than 70% of the children during the follow-up. Especially in patients with mutations in ALOXE3 and ALOX12B, mIASI scores dropped significantly. The most common phenotype observed in this study was designated 'mild fine scaling ichthyosis'. Severe palmoplantar involvement occurred in patients with KRT1 and ABCA12 mutations; most patients demonstrated hyperlinearity as a sign of dryness and scaling. Weight was mainly in the normal range and negatively correlated with the severity of skin involvement.

CONCLUSIONS

Congenital ichthyosis that self-improves and evolves with mild fine scaling ichthyosis was the most common phenotype observed in our patients. This type might be underdiagnosed if the genetic diagnosis is not performed in the first year of life. mIASI is an easy and fast instrument for scoring disease severity and adding additional points for palmoplantar involvement might be valuable.

A study on echocardiographic findings in hospitalized patients with connective tissue diseases

OBJECTIVE

To determine the prevalence of echocardiographic findings and their change over time in patients with connective tissue diseases (CTDs) and to analyse which findings were associated with escalation of immunosuppressive therapy.

METHOD

We conducted a retrospective cohort study of consecutive hospitalized patients from a tertiary rheumatology referral centre who received transthoracic echocardiography between 1 January 2006 and 31 December 2015. We tested for associations between echocardiographic findings and treatment escalation via Fisher's exact test; p < 0.05 was considered significant. Escalation of therapy was defined by dosage of glucocorticoids and type of disease-modifying anti-rheumatic drug. The clinical relevance of echocardiographic findings concerning change in immunosuppressive therapy was recorded.

RESULTS

In total, 1004 patients were included (865 females), with a total of 1660 echocardiographic examinations. The most frequent findings were mitral, tricuspid, and aortic valve regurgitation (found in 36.7%, 25.4%, and 17.7% of all patients), aortic valve sclerosis (20.1%), left ventricular dysfunction (21.5%), and left atrial dilatation (19.2%). Only pericardial effusions were more frequent in cases with treatment escalation (10.9% of cases with escalated therapy vs 6.9% of cases without, p = 0.007). In 314 patients who received follow-up examinations, echocardiographic findings were found to change between examinations. Only 73 of all 1660 examinations were discussed in depth considering the treatment strategy in the hospital discharge letter.

CONCLUSION

Patients with CTDs exhibited a wide, dynamically changing spectrum of echocardiographic abnormalities. Most findings neither reflected disease activity nor appeared to influence the therapeutic regimen.

OP0283 DOES TNF-INHIBITION DECREASE THE RISK OF SEVERE COVID-19 IN RMD-PATIENTS?

Background:

Patients with rheumatic and musculoskeletal diseases (RMD) might have an increased risk for infection due to their immunomodulatory treatment, secondary to their disease and comorbidities. Recent studies suggest a decreased risk of severe COVID-19 in RMD-patients treated with biologics.

Objectives:

The aim of this study was to assess courses of RMD patients treated with TNF-inhibitors (TNF-I) included in the German COVID-19 registry.

Methods:

In the German physician-reported COVID-19-RMD registry, patients with an RMD and confirmed SARS-CoV-2-infection were documented (data entered between March 30, 2020 and January 30, 2021). We analysed TNF-I treated patients, their course and outcome of the infection. Data were compared to RMD-patients treated with other immunomodulatory drugs (OID) than TNF-I.

Results:

A total of 269 patients were treated with a TNF-I (57% female) compared to 874 patients who were treated with OID (68% female). Median age was 52 years (range: 19-87) in the TNF-I-group versus 58 years (range: 18-91) in the OID-group. Rheumatoid arthritis was the most common diagnosis (38% in TNF-I-group vs. 52% in the OID-group), followed by ankylosing spondylitis (32% vs. 6%), psoriatic arthritis (22% vs. 11%) and other RMD (9% vs. 31%). Adalimumab (35%) and etanercept (35%) were the most frequently used TNF-I (tab. 1). Glucocorticoids (GC) were used in 22% of TNF-I-treated patients and in 42% of the OID-group.

Under TNF-I, stable disease was reported prior to the SARS-CoV-2-infection in 53% of the patients (OID-group: 47%), followed by low disease activity in 35% (OID: 34%), moderate disease activity in 6% (OID: 12%) and high disease activity in 4% (OID: 3%). Most frequent comorbidities were arterial hypertension (29% under TNF-I vs. 35% under OID), diabetes (8% vs. 11%) and cardiovascular diseases (7% vs. 12%).

The most common reported COVID-19 symptoms were dry cough (57% vs. 55%), fever (53% vs. 61%) and fatigue (50% vs. 49%). Hospitalization due to SARS-CoV infection was required in only 12% of the TNF-I-treated cases vs. in 29% in the OID-group. Oxygen treatment was necessary in 5% of the patients under TNF-I compared to 22% under OID and invasive ventilation in 2% in the TNF-I-group compared to 6% under OID. Most notably, no fatal courses of COVID-19 were reported among the 269 RMD-patients treated with TNF-I versus 49 deaths in the 874 cases (5.6%) treated with OID. Focussing on the hospitalizated TNF-I patients, the rate of concomitant GC use (p<0.001) and higher disease activity (p=0.005) was significant higher (tab.1).

Conclusion:

High or moderate RMD-disease activity is an important factor associated with severity of COVID-19 including mortality. In this large cohort RMD patients treated with TNF-I show a low hospitalisation rate and no fatal course. This is reassuring for patients and treating rheumatologists to use TNF-I to control RMD disease activity. The use of glucocorticoids and high disease activity seem to counteract possible protective effects of TNF-I.

POS1261 DISEASE ACTIVITY AND PAIN LEVELS ARE NOT INFLUENCED BY THE CURRENT COVID19 PANDEMIC IN PATIENTS WITH RHEUMATIC DISEASES IN GERMANY – DATA FROM THE GERMAN COVID-19 PATIENT SURVEY

Background:

The current pandemic constitutes an entirely new situation for patients as well as physicians. The insecurity of the early phase, shutdowns, increasing infection rate and appearing SARS-CoV2 mutations have created a situation that makes live difficult especially for chronic diseases i.e. patients with rheumatic and musculoskeletal diseases (RMD) and their treating physicians. The psychosocial burden that is created by this special situation is completely unknown and is estimated to be higher in patients than in the general population.

Objectives:

In order to measure the impact on our patients, the German COVID19-Rheuma patient survey was set up in April 2020, during Germany’s first shut down.

Methods:

The German COVID19-Rheuma patient survey is a patient reported longitudinal online survey where patients with RMD who registered between April and July 2020 are asked on a monthly base using an online survey on social, personal, medical factors, whether a COVID19 infection occurred, isolation measures were changed and scores regarding stress and anxiety are recorded. Between April and July 2020, 637 patients registered and completed a first survey. Up to January 2021, about 400 patients are still enrolled.

Here we present an interim analysis of the first 6 months regarding patients that were enrolled in April and May during the first shut-down. This first analysis compares the situation in the first lockdown to July, a phase with very low infection numbers in Germany, and to November, the beginning of the second lockdown.

Results:

150 patients (87% female) were enrolled in April/early May 2020. Mean age was 48 years (range 11-89). The majority of patients suffered from rheumatoid arthritis (51%), followed by psoriatic arthritis (17%), other spondyloarthropathies (10%) and connective tissue diseases (10%).

The majority of patients received antirheumatic therapies: 32% glucocorticoids (GC), 31% cDMARDs, 21% TNF inhibitors, 7% Jak inhibitors, and 9% other biologicals. Of the patients treated with GC, 25% were on GC monotherapy.

In the first lockdown, 26% of patients were working remotely and 24% were self-isolating (doubles included). Additionally, 48% were using masks that were not mandatory at that time and 41% were using disinfection in a regular manner. The rates for remote work and self-isolation did not change significantly over time while the mask use increased to 98% with the official obligation to do so. The use of disinfectants increased to 88% in November.

Regarding disease activity, no change in patient global assessment could be observed over time (4.3 ± 2.5 vs. 4.0 ±2.6 and 4.0 ± 2.5). Self-reported pain was also stable over time as were sleep disturbances. While 48.2% of patients who were receiving physiotherapy paused in April, only 10 and 14% did so in July and November, respectively. 11% of the patients paused their medication in the first lockdown, whereas only 2.75% did so in July and 3.4% in November. Contact with the treating rheumatologist was maintained over time in the majority of cases.

Conclusion:

While in the beginning of the pandemic the insecurity was considerable and the concern that the fear for infection would lead to inadequately treated patients with RMDs, we here show for the first time that on the one hand our patients were timely in taking adequate measures to keep themselves safe (e.g. self-isolating, mask use) and adapted to the clinical situation in not pausing their medication. Altogether, in this alert cohort, the pandemic did not lead to an increase of patient-reported disease activity in the first six months.

[Quality in acute inpatient rheumatology 2021 : Current aspects of the KOBRA quality label of the Association of Rheumatological Acute Care Clinics]

Mit einer umfassenden gesundheitspolitischen Qualitätsoffensive ab 2021 sollen die Qualität und Transparenz in der Versorgung von Menschen mit Krankheiten in Krankenhäusern in Deutschland verbessert werden. Gesetzliche Vorgaben zu Mindestmengen und die Ausweitung von Qualitätsverträgen zwischen Kostenträgern und Krankenhäusern sowie die Verwendung von planungsrelevanten Qualitätsindikatoren für eine bedarfs- und qualitätsorientierte Weiterentwicklung der stationären Versorgung werden den Wettbewerb in der Versorgungsqualität zwischen den Krankenhäusern verstärken. Dem Thema „Entwicklung und Definition von Qualität in der Medizin“ hat sich auch der Verband der Rheumatologischen Akutkliniken e. V. (VRA) schon früh nach der Gründung im Jahr 1998 umfassend angenommen. Im Zentrum der akutstationären Qualitätssicherung stehen verbindlich festgelegte Strukturkriterien in Verknüpfung mit dem 2003 in der Rheumatologie gestarteten und bis heute kontinuierlich durchgeführten KOBRA-Projekt (Kontinuierliches Outcome Benchmarking in der Rheumatologischen Akutversorgung) mit der Messung von Prozess- und Ergebnisqualität. Auf der Basis dieses Rahmenkonzeptes (Erfüllung der Strukturkriterien und Durchführung des KOBRA-Projektes) können erfolgreich teilnehmende rheumatologische Einrichtungen für jeweils 2 Jahre das KOBRA-Label erwerben, welches von der Projektleitung – dem aQua-Institut – vergeben wird. Die herausragende Stellung des KOBRA-Projektes wird beispielhaft anhand von Datenauswertungen des Projektzyklus 2018 gezeigt mit Auswertungen zum Therapiestrategiewechsel bei aktiver rheumatoider Arthritis, Diagnosesicherung von Kollagenosen und Vaskulitiden während des stationären Aufenthaltes sowie zur partizipativen Entscheidungsfindung bei rheumatoider Arthritis. Auf den gesundheitspolitisch geforderten „Paradigmenwechsel – weg vom Bett, hin zu einer leistungs-, bedarfs- und qualitätsorientierten Planung“ – ist die akutstationäre Rheumatologie mit der Verankerung von Projekten zur Struktur‑, Prozess- und Ergebnisqualität sehr gut vorbereitet. Für die in der vom Gemeinsamen Bundesausschuss (G-BA) erstellten Richtlinie zu „Rheumatologischen Zentren“ geforderten Qualitätssicherung ist das KOBRA-Projekt ebenfalls eine sehr gute Voraussetzung.

Hyperbaric oxygen therapy in wound healing in mice

ABSTRACT We investigated the local and systemic effects of hyperbaric oxygen therapy in BALB/C mice, exposed to two different exposure times, under 2.4 atmosphere (ATM). Fifteen animals were divided into three groups (GI, GII and Control) and underwent a surgical excision of a skin fragment of approximately one square centimeter of the dorsal region. The wounds were treated and monitored for 21 days. In the control group, the wound was cleaned once a day with sterile 0.9% NaCl solution. GI and GII mice were submitted to daily hyperbaric oxygen therapy of 30 or 60minutes sessions, respectively. The wounds were photographed every three days and their surfaces were analyzed by an image analyzer. At 21 days, all animals were euthanatized for histopathological analysis of the skin, lungs and liver in order to identify eventual alterations in wound healing or in the analyzed organs. Animals belonging to GI showed a faster skin wound healing in comparison to the other groups. Animals from GII, however, showed a delayed wound healing process and exhibited lung and microcirculatory alterations. These findings allow us to conclude that the exposure time to the oxygen in hyperbaric environment is crucial and can help or disturb skin wound healing or even be deleterious to other organs.

Joint Statement (DZK, DGRh, DDG) on the Tuberculosis Risk with Treatment Using Novel Non-TNF-Alpha Biologicals

BACKGROUND

 While the risk of tuberculosis (TB) reactivation is adequately documented in relation to TNF-alpha inhibitors (TNFi), the question of what the tuberculosis risk is for newer, non-TNF biologics (non-TNFi) has not been thoroughly addressed.

METHODS

 We conducted a systematic review of randomized phase 2 and phase 3 studies, and long-term extensions of same, published through March 2019. Of interest was information pertaining to screening and treating of latent tuberculosis (LTBI) in association with the use of 12 particular non-TNFi. Only rituximab was excluded. We searched MEDLINE and the ClinicalTrial.gov database for any and all candidate studies meeting these criteria.

RESULTS

 677 citations were retrieved; 127 studies comprising a total of 34,293 patients who received non-TNFi were eligible for evaluation. Only 80 out of the 127 studies, or 63 %, captured active TB (or at least opportunistic diseases) as potential outcomes and 25 TB cases were reported. More than two thirds of publications (86/127, 68 %) mentioned LTBI screening prior to inclusion of study participants in the respective trial, whereas in only 4 studies LTBI screening was explicitly considered redundant. In 21 studies, patients with LTBI were generally excluded from the trials and in 42 out of the 127 trials, or 33 %, latently infected patients were reported to receive preventive therapy (PT) at least 3 weeks prior to non-TNFi treatment.

CONCLUSIONS

 The lack of information in many non-TNFi studies on the number of patients with LTBI who were either excluded prior to participating or had been offered PT hampers assessment of the actual TB risk when applying the novel biologics. Therefore, in case of insufficient information about drugs or drug classes, the existing recommendations of the German Central Committee against Tuberculosis should be applied in the same way as is done prior to administering TNFi. Well designed, long-term "real world" register studies on TB progression risk in relation to individual substances for IGRA-positive cases without prior or concomitant PT may help to reduce selection bias and to achieve valid conclusions in the future.

[Future of acute inpatient rheumatology in Germany : Statement of the Boards of the German Society for Rheumatology and the Association of Rheumatological Acute Clinics on hospital planning North-Rhine/Westphalia 2019 for the discipline rheumatology]

Im September 2019 wurde vom Ministerium für Arbeit, Gesundheit und Soziales (MAGS) in NRW ein Gutachten zur Krankenhausplanung veröffentlicht. Hierin wurde eine grundlegende Reform der Krankenhausplanung empfohlen, indem zukünftig eine Bedarfsplanung auf der Grundlage einer detaillierten Ausweisung von Leistungsbereichen und Leistungsgruppen erfolgen soll. Nach Aufforderung durch das MAGS NRW hat auch die Deutsche Gesellschaft für Rheumatologie (DGRh) mit Unterstützung des Verbandes Rheumatologischer Akutkliniken (VRA) hierzu Stellung genommen.

[Mission statement from rheumatologists in the German Society of Rheumatology (DGRh e. V.) : We live rheumatology. German version]

Systemic disease demands systemic thinkers. In this mission statement we define rheumatology, describe the role of the German Society of Rheumatology and the rheumatologist's spirit to their discipline. Rheumatologists are dedicated to improving the quality of life of their acute, chronic, and rehabilitative patients on the basis of up to date evidence and strong physician-patient relations. We think, act and interact systemically, scientifically, consistently, transparently, reliably, inclusively, innovatively and enthusiastically.

[Delegation of medical tasks in rheumatology]

Modern rheumatology enables better and earlier diagnosis and therapy of inflammatory rheumatic system diseases. At the same time, the requirements for the care of rheumatologic patients have risen considerably for non-medical assistant professions and specialists for nursing professions. Since 2006 there has been established an education curriculum "Rheumatological Specialist Assistant DGRh-BDRh" (RFA) with the training to become a "Rheumatological Specialist Assistant (DGRh-BDRh)". In Europe and in parallel in Germany, assistant professions are increasingly involved in the early detection and care of patients with rheumatic diseases and entrusted with tasks.In this work, the overarching principles for delegation of medical tasks to RFA and recommendations for the delegation are published by the Commission for Delegation of the German Society for Rheumatology (DGRh). These recommendations are based on the requirements of the German Medical Association and have been legally evaluated. With the extension of the training of the RFA board certification is aimed for "MFA for Rheumatology". These recommendations enable more transparency and security for delegating doctors and the delegated RFA's.

AB1129 PREVALENCE OF FINDINGS IN ROUTINE ABDOMINAL ULTRASOUND IN PATIENTS WITH CONNECTIVE TISSUE DISEASES AND THEIR IMPACT ON DISEASE MANAGEMENT

Background:

Patients with connective tissue diseases (CTD) are often screened for abdominal organ involvement with ultrasound.

Objectives:

To analyse the prevalence of routine abdominal ultrasound findings in different CTD entities and their impact on therapeutic decisions.

Methods:

Retrospective chart review of all in-patients from a tertiary rheumatological referral center with CTD diagnosis and abdominal ultrasound examination between January 1st 2006 and December 31st 2015. Descriptive statistics were used to describe patient characteristics and frequencies of ultrasound findings. To determine whether findings impacted therapeutic decisions, we analysed if they were discussed in the hospital discharge letter.

Results:

1.092 patients with a total of 1.695 hospitalizations were analysed. Mean age was 55.1 years (range: 17-90 years, SD: 15.8), mean disease duration was 6.4 years (range: 0.0-52.8 years, SD: 9.1). 87.5 % were female.

Table 1 shows the frequency of findings per CTD entity. 48 out of all 1.695 examinations were discussed in the hospital discharge letter. In 30 cases, the physician described the ultrasound results as pivotal for therapeutic decision-making.

CO0004 OLDER AGE, CARDIOVASCULAR COMORBIDITY AND GLUCOCORTICOSTEROIDS ARE RISK FACTORS FOR COVID-19 HOSPITALISATION IN PATIENTS WITH INFLAMMATORY RHEUMATIC DISEASES: FIRST RESULTS OF THE GERMAN COVID-19-IRD REGISTRY

Background:

Patients with inflammatory rheumatic diseases (IRD) and infection with SARS-CoV-2 may be at risk to develop a severe course of COVID-19. To gather knowledge about SARS-CoV-2 infections in IRD patients, a national registry was established to elucidate IRD specific profiles of COVID-19.

Objectives:

To identify risk factors for hospitalisation.

Methods:

Patients from the German registry on SARS-CoV-2 infection in IRD were analysed. Patients are enrolled with a pre-existing IRD and a positive lab-result for a SARS-CoV-2 infection. The main outcome parameter was hospitalisation versus non-hospitalisation. Multivariable logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI). Covariates included in the model were age group, gender, key comorbidities (cardiovascular, lung diseases, chronic renal insufficiency), prior and/or current use of glucocorticosteroids (GC) or NSAIDs and remission.

Results:

Until May 17th, 2020, data from 192 IRD patients with SARS-CoV-2 infection were reported (67 males; 124 females; 1 diverse). 64 patients were hospitalised, 21 patients were ventilated non-invasively/invasively and 15 patients died.

Baseline characteristics are shown in table 1, stratified into the patient groups non-hospitalisation, hospitalisation without ventilation, and hospitalisation with ventilation. Non-hospitalised patients were younger, had less comorbidities and were less often treated with GC. In the group of hospitalised patients compared to non-hospitalised patients more patients were male (42% vs 32% male) with an even higher proportion in the ventilated patient group (57% male).

In the multivariable logistic regression model, age>65 years (OR 5.1; 95%CI 2.3-11.4), cardiovascular comorbidity (OR 2.3; 95%CI 1.0-5.0), and prior and/or current treatment with GC (OR 2.6; 95%CI 1.2-5.4) were independently associated with hospitalisation.

Conclusion:

As has been described for COVID-19 in general, also in IRD male gender may be associated with a more severe course of the infection as the descriptive analysis of data shows. Risk factors for SARS-CoV-2 infection-dependent hospitalisation in IRD patients include age (>65 years), cardiovascular comorbidities, and prior and/or current treatment with GC.
