Electrocardiographic Abnormalities in Hospitalized Patients with COVID-19 and the Associations with Clinical Outcome

The cardiovascular (CV) system can often be affected during SARS-CoV-2 infection and several acute manifestations, such as myocardial infarction, pericarditis, myocarditis and arrhythmias have been described. We provide a retrospective overview of electrocardiographic (ECG) features and their relationship with clinical outcomes in a cohort of patients admitted to our COVID-19 Unit between November 2020 and May 2021. Resting standard 12-lead ECGs were performed in all patients at admission and in those recovering from SARS-CoV-2 infection also at discharge. Clinical and serological records alongside ECG measurements were retrospectively evaluated and statistical analysis was performed to identify relationships between variables. A total of 123 patients (44% females) with a mean age of 73.9 years were enrolled. Ninety-five (77%) patients recovered from SARS-CoV-2 infection and were discharged while 28 (23%) died in hospital. Almost 90% of patients displayed at least one CV risk factor and 41 (33%) patients had at least one previous CV event. We observed that heart rate, corrected QT interval dispersion (QTcd) and inverted T waves are independently associated with in-hospital death and inverted T waves show the strongest association. This association remained significant even after correcting for the number of CV risk factors at baseline and for the type of CV risk factor at baseline. Our study demonstrated that some ECG abnormalities at admission are independently associated with in-hospital death regardless of pre-existing CV risk factors. These findings may be of particular relevance in clinical settings with limited access to advanced techniques, such as cardiac magnetic resonance and could help improve the outcomes of patients with cardiac involvement related to SARS-CoV-2 infection.

Immune-mediated inflammatory diseases after anti-SARS-CoV-2 vaccines: new diagnoses and disease flares

Objective

New-onset immune-mediated inflammatory diseases (IMIDs) and flares of pre-existing IMIDs have been reported following anti- SARS-CoV2 vaccination. Our study aimed at describing a retrospective cohort of patients developing new-onset IMIDs or flares of known IMIDs within 30 days after any anti-SARS-CoV2 vaccine dose.

Methods

We evaluated clinical records of all inpatients and outpatients referring to our institution between February 2021 and February 2022 with any clinical manifestations. We then selected those having received any anti-SARS-CoV2 vaccine dose within the prior 30 days and classified them as having or not a previous IMID according to predefined criteria. We recorded new-onset IMIDs or flares of known IMIDs and investigated any relationship with demographic, clinical and serological variables.

Results

153 patients that received any anti-SARS-CoV2 vaccine dose within the previous 30 days were included of which 45 (29%) already had a diagnosis of IMID while 108 (71%) had no previously diagnosed IMID. 33 (30%) of the 108 patients, were diagnosed with a new-onset IMID. Pericarditis, polymyalgia rheumatica and vasculitis were the most frequent conditions. Among the 45 patients that already had an IMID, disease flare was the reason for referral in 69% of patients. Patients with an IMID flare had a lower number of comorbidities and tended to be younger compared with those who developed other conditions after anti-SARS-CoV2 vaccination.

Conclusion

We provided a retrospective overview of a cohort of patients who developed new-onset IMIDs or flares of known IMIDs within 30 days after any dose of anti-SARS-CoV2 vaccine. While vaccination campaigns proceed, postvaccination surveillance programmes are ongoing and hopefully will soon clarify whether a causal relationship between vaccines and new-onset/flares of IMIDs exists.

Gender equity in academic rheumatology, current status and potential for improvement: a cross-sectional study to inform an EULAR task force

OBJECTIVES

Evidence on the current status of gender equity in academic rheumatology in Europe and potential for its improvement is limited. The EULAR convened a task force to obtain empirical evidence on the potential unmet need for support of female rheumatologists, health professionals and non-clinical scientists in academic rheumatology.

METHODS

This cross-sectional study comprised three web-based surveys conducted in 2020 among: (1) EULAR scientific member society leaders, (2) EULAR and Emerging EULAR Network (EMEUNET) members and (3) EULAR Council members. Statistics were descriptive with significance testing for male/female responses assessed by χ² test and t-test.

RESULTS

Data from EULAR scientific member societies in 13 countries indicated that there were disproportionately fewer women in academic rheumatology than in clinical rheumatology, and they tended to be under-represented in senior academic roles. From 324 responses of EULAR and EMEUNET members (24 countries), we detected no gender differences in leadership aspirations, self-efficacy in career advancement and work-life integration as well as the share of time spent on research, but there were gender differences in working hours and the levels of perceived gender discrimination and sexual harassment. There were gender differences in the ranking of 7 of 26 factors impacting career advancement and of 8 of 24 potential interventions to aid career advancement.

CONCLUSIONS

There are gender differences in career advancement in academic rheumatology. The study informs a EULAR task force developing a framework of potential interventions to accelerate gender-equitable career advancement in academic rheumatology.

AB0524 RELATIONSHIP BETWEEN SERUM URIC ACID, CARDIOVASCULAR RISK AND INFLAMMATORY STATUS IN PRIMARY SJÖGREN’S SYNDROME

Background

An unhealthy diet, with or without impaired renal urate excretion, is the most frequent cause of hyperuricemia. Despite its pivotal role in the pathogenesis of gout, the clinical relevance of serum uric acid (SUA) levels goes well beyond the simple association with gout and/or nephrolithiasis. Several studies pointed to hyperuricemia as cardiovascular (CV) risk factor in the general population therefore, the 2018 guidelines of the European Society of Cardiology and the European Society of Hypertension included the assessment of uricemia among the screening tests to be performed in hypertensive patients. Furthermore, in view of the association between hyperuricemia and mortality (both CV and all-cause) and CV events, it is conceivable that cardiovascular damage begins with much lower levels of uricemia. In this context, the first results of the URRAH (Uric Acid Right for Heart Health) study identified a uricemia threshold value of 4.7 mg/dL for all-cause mortality and 5.6 mg/dL for CV mortality1.

Objectives

Since patients with primary Sjögren’s syndrome (pSS) have a higher risk of CV events compared to the general population, we aimed to explore how uricemia correlates with other CV risk factors and previous CV events in patients with pSS and without gout.

Methods

A cross sectional study was conducted recruiting consecutive patients with pSS without history of gout. SUA was measured upon recruitment alongside the assessment of disease activity (EULAR Sjögren’s syndrome disease activity index, ESSDAI and ClinESSDAI), patient reported symptoms (EULAR Sjögren’s syndrome patient reported symptoms, ESSPRI), CV risk factors including hypertension and diabetes among others, and previous CV events. Dietary habits were also explored with various food frequency questionnaires.

Results

One hundred and three patients with pSS were enrolled. SUA levels ranged between 2.9 and 6.8 mg/dl and, according to the cut-off values of the URRAH study, 16 (16%) patients had SUA levels >4.7 mg/dL while 5 (5%) had SUA levels >5.6 mg/dL. Patients with SUA levels >4.7 mg/dL were more likely males (20% vs 3%) with a higher number of CV risk factors compared to patients with SUA levels <4.7mg/dL. No differences were observed regarding dietary habits across groups. Disease activity assessed with both ESSDAI and ClinESSDAI was significantly higher in patients with SUA levels >4.7 mg/dL compared to patients with SUA levels <4.7 (9.3 vs 6.3 p= 0.04 and 9.0 vs 6.0 p=0.03). Conversely, patient reported symptoms (total ESSPRI and individual VAS scales for total dryness, xerostomia, xerophtalmia, pain and fatigue) did not differ across groups. Logistic regression analysis confirmed the association of SUA values >4.7 mg/dL and a higher number of CV risk factors (OR 2.8; 95% CI=1.2-6.5; p=0.016).

Conclusion

Accumulating evidence highlights the emerging role of hyperuricemia as an independent CV risk factor, but no data are available in pSS patients. This is the first study demonstrating that SUA levels >4.7 mg/dL correlate with both a higher number of CV risk factors and a higher disease activity in pSS patients. Large interventional studies are needed to clarify the possible benefits of urate-lowering treatments in pSS patients.

POS0723 DIETARY HABITS AND THE IMPACT ON CLINICAL FEATURES IN PRIMARY SJOGREN’S SYNDROME

Background

In recent years, increasing evidence on the role of diet on chronic conditions, including cardiovascular diseases (CV) and rheumatic and musculoskeletal diseases (RMDs) has accrued. Most studies exploring the possible role of nutrients and dietary patterns on both the risk to develop RMDs in the general population and the natural history of the disease in patients with established RMDs pertain to rheumatoid arthritis. Data in patients with established primary Sjogren’s syndrome (pSS) is lacking.

Objectives

To explore dietary habits and their relationship with metabolic and inflammatory features in a cohort of patients with established pSS.

Methods

Consecutive patients with pSS were recruited and dietary habits over the previous 12 months were explored. Adherence to the Mediterranean Diet was assessed with the 14-item PREvencion con DIeta MEDiterranea’ (PREDIMED) tool and the 28-item Mediterranean Lifestyle (MEDLIFE) index. Adherence to the Dietary Approaches to Stop Hypertension (DASH) was estimated using a score based on 8 food items. Tea/herbal tea and coffee intake were also explored and clinical/serological records were retrospectively collected.

Results

We enrolled 105 patients with pSS (95% females) with a mean age of 59 years. According to the PREDIMED score 32 (31%) patients had a good adherence to the Mediterranean Diet, 64 (61%) a medium adherence and only 9 (8%) a poor adherence. According to the DASH score, 74 (71%) patients had low adherence and 31 (29%) had high adherence. When dividing patients according to the extent of adherence to either of the dietary patterns and correlating the diet adherence scores to disease specific variables some associations emerged. The PREDIMED score was inversely correlated with disease activity, as measured by the EULAR Sjögren’s syndrome disease activity index (ESSDAI) (Spearman’s rho=-0.27, p= 0.009) and ClinESSDAI (Spearman’s rho=-0.26, p=0.01) revealing that a higher adherence to the Mediterranean Diet was associated with lower disease activity. With regard to the MEDLIFE, the total of blocks 1 and 2, that are related to Mediterranean foods and dietary habits, did not correlate with the total of block 3 (related to other healthy habits such as physical activity), meaning that the patients adhering the most to the Mediterranean Diet not necessarily had an overall healthy lifestyle. Adherence to DASH was not associated with disease activity. With regard to individual nutrients, fish consumption was associated with a lower prevalence of hypertension as observed in the general population. Higher intake of red meat was associated with higher values of self-reported pain (Spearman’s rho=-0.3; p=0.01) while high wholegrain intake was associated with a lower number of coexisting CV risk factors (OR=0.7; 95% CI=0.52-0.97; p=0.03).

Conclusion

Adherence to the Mediterranean Diet, with particular attention to high intake of fish and wholegrains and low intake of red meat, may be beneficial on various domains in pSS, such as the CV system and the inflammatory environment, and as such should be recommended to patients with this disease.

AB0364 THE EFFECT OF BIOLOGIC AND TARGETED SYNTHETIC DISEASE MODIFYING ANTI-RHEUMATIC DRUGS ON WORK PARTICIPATION IN LONGSTANDING RHEUMATOID ARTHRITIS: RESULTS FROM A SYSTEMATIC LITERATURE REVIEW

Background

Work participation (WP) is a top priority for people with RA and a determinant of patients’ quality of life. Therefore, assessing the effect of interventions on WP outcomes is important.

Objectives

To review the effect of b/tsDMARDs on employment status (ES), sick leave (SL) and presenteeism in patients with longstanding RA.

Methods

A systematic literature review up to October 2021 was conducted using the PICOT framework (Figure 1). Two researchers independently screened abstracts, then full texts were reviewed to determine eligibility. Data from eligible articles were extracted. Heterogeneity and insufficient reporting of data precluded meta-analysis.

Results

We included 42 studies:16 randomized controlled trials (RCT) and 26 longitudinal observational studies (OBS). All studies were conducted with background therapy with csDMARDs; 33 (78%) in csDMARD-IR patients. RCTs provided short-term data only (≤24 weeks (w)) which have limited relevance for WP outcome domains such as ES1. OBS reported long-term data (≤ 5 years), albeit imposing challenges due to lack of random allocation to interventions and often lack of a comparator. Regarding ES, 6 RCTs and 4 OBS did not report significant differences in bDMARD-treated patients vs background csDMARDs. For SL (19 studies), 1 RCT showed that etanercept significantly reduced RA-related SL up to 12-16w; however, one OBS showed no such effect on the long-term. Conflicting results were obtained by 2 RCTs on baricitinib. Most compounds assessed in the 12 OBS without comparator reported improvement in SL up to 104w. For presenteeism (11 studies; Table 1), 4 RCTs showed that etanercept, golimumab, certolizumab pegol, baricitinib and peficitinib were superior to PBO+csDMARDs up to 12w. Two H2H studies assessing sarilumab and baricitinib vs adalimumab observed comparable presenteeism in all treatment arms at 12-16w.

Conclusion

Short-term data from RCTs with background therapy with csDMARDs showed adding b/tsDMARDs was more effective than PBO in improving presenteeism. However, data on SL are conflicting and the positive results come from OBS without comparator. Future studies should consider existing guidance on the assessment of WP outcome domains to allow pooling and meta-analysis1.

POS0525 ARE BIOLOGIC AND TARGETED SYNTHETIC DISEASE MODIFYING ANTI-RHEUMATIC DRUGS ASSOCIATED WITH WORK PARTICIPATION IMPROVEMENT IN EARLY RHEUMATOID ARTHRITIS? A SYSTEMATIC REVIEW AND META-ANALYSIS

Background

In early RA, the benefit of treatment with b-/tsDMARDs on work participation (WP), a top-three social role in RA, has seldom been studied.

Objectives

To review the effect of treatment with b-/tsDMARDs on employment status (ES), presenteeism and sick leave (SL), in patients with early RA.

Methods

A systematic literature review (SLR) was conducted in key electronic databases up to October 2021, to include RCTs assessing the effect of treatment with b-/tsDMARDs vs any comparator on ES, presenteeism and SL in patients with RA (≤ 3y). Two reviewers independently identified eligible studies and extracted data. Random-effects meta-analysis was only performed if ≥3 studies were conducted in comparable populations, assessing WP outcome similarly. Statistical heterogeneity was assessed with I2.

Results

From 7129 records (65 full-text articles screened), 11 RCTs were included in the SLR (7 in csDMARD naïve patients; 2 in inadequate responder to csDMARDs; 1 bDMARD tapering after initial combination with MTX, and 1 strategy study). Large heterogeneity was found across WP outcomes, measurement instruments, interventions and comparators (Table 1), which together with insufficient data reporting hampered meta-analysis of most outcomes. For ES, to allow meta-analysis, all outcomes were converted to employment loss, for which individual study Odds ratios (OR) were computed. The pooled OR of 4 studies with 779 patients treated with adalimumab, infliximab or baricitinib (Figure 1) showed a lower likelihood of employment loss at weeks 56 to 104 in those treated with MTX+b/tsDMARDs compared to MTX+PBO (OR: 0.65; 95% CI:0.43-0.99). For presenteeism and SL, 33/40 (83%) between-group comparisons showed improvement in favour of b-/tsDMARDs, but an effect size was reported or possible to compute for only 12 comparisons, of which 8 (67%) were statistically significant.

A protective effect against employment loss was observed in patients with early RA treated with MTX+b-/tsDMARDs compared to MTX monotherapy. The methodological heterogeneity and insufficient reporting hampers clear conclusions regarding the beneficial effects of b-/tsDMARDs on presenteeism and SL. Efforts to uniformize future studies with WP as outcome by following recently developed points to consider are crucial1.

EULAR points to consider for the use of imaging to guide interventional procedures in patients with rheumatic and musculoskeletal diseases (RMDs)

OBJECTIVES

To develop evidence-based Points to Consider (PtC) for the use of imaging modalities to guide interventional procedures in patients with rheumatic and musculoskeletal diseases (RMDs).

METHODS

European Alliance of Associations for Rheumatology (EULAR) standardised operating procedures were followed. A systematic literature review was conducted to retrieve data on the role of imaging modalities including ultrasound (US), fluoroscopy, MRI, CT and fusion imaging to guide interventional procedures. Based on evidence and expert opinion, the task force (25 participants consisting of physicians, healthcare professionals and patients from 11 countries) developed PtC, with consensus obtained through voting. The final level of agreement was provided anonymously.

RESULTS

A total of three overarching principles and six specific PtC were formulated. The task force recommends preference of imaging over palpation to guide targeted interventional procedures at peripheral joints, periarticular musculoskeletal structures, nerves and the spine. While US is the favoured imaging technique for peripheral joints and nerves, the choice of the imaging method for the spine and sacroiliac joints has to be individualised according to the target, procedure, expertise, availability and radiation exposure. All imaging guided interventions should be performed by a trained specialist using appropriate operational procedures, settings and assistance by technical personnel.

CONCLUSION

These are the first EULAR PtC to provide guidance on the role of imaging to guide interventional procedures in patients with RMDs.

POS0888 NON-SURGICAL LOCAL TREATMENTS FOR DIGITAL ULCERS IN SYSTEMIC SCLEROSIS: A SYSTEMATIC LITERATURE REVIEW

Background

Digital ulcers(DUs) in systemic sclerosis(SSc) represent a major clinical challenge. There are no recommendations for the local management of SSc-DUs. Systemic therapy is considered the standard of care. However, there is a strong rationale for local approaches to DU by avoiding side effects from systemic therapies. The World Scleroderma Foundation DU Working Group intends to develop evidence-based recommendations for DU management including local, non-surgical treatment(ln-sT).

Objectives

To summarise the literature on the safety and efficacy of ln-sT for SSc-DUs.

Methods

A systematic literature review(SLR) of papers describing the use of ln-sT for DU in SSc was performed up to May 2021 according to the PICO framework. References were independently screened by two reviewers who independently assessed the full text of eligible articles and extracted data.

Results

Among 790 retrieved references, 12 were included. Median(range) number of patients per study was 9(7–84), mean age ranging from 37 to 62.5 years. In 5(41%) studies a control group was included. Background systemic therapies are summarized in Table 1. The most studied treatment was botulin toxin A(BTA). It was used as hand injection in 3 studies (median dose ranging from 90 to 150 U) and as 50 U single finger injection in 1 study. Healing rate after a median time of 8-49 weeks ranged from 71% to 100%. In 2 studies a reduction in VAS pain was observed from 20% to 100%. Transient muscle weakness was the most common side effect in 10% of patients. Amniotic(Am) and hydrocolloid membranes(HyM) were used in 1 study each. They were associated with a good healing rate, statistically significant for the HyM. Tadalafil 2% cream was studied in 1 study and was associated with a reduction in the median DU number from 1.6 to 1 per patient after a median time of 4 weeks and a reduction by 1.4 point in the 10-mm VAS scale. Vitamin E gel was shown to be associated with a statistically significant reduction in the healing time compared to SoC alone in 1 RCT(13.2 ± 2.7 versus 20.9 ± 3.6 weeks, P=<0.001). Low-level light therapy, hydrodissection and corticosteroid injection and extracorporeal shock wave(ESW) were evaluated in 1 study each. They were all associated with positive outcomes which was statistically significant only for the ESW. The only negative trial examined dimethyl sulfoxide and was associated with local toxicity.

Conclusion

Our SLR supports interest to develop ln-sTs for SSc-DUs. The number of studies is limited and mainly case reports and small single studies are present. Treatments were well tolerated and there was evidence of efficacy for BTA, vitamin E, ESW and HyM in refractory DUs. The evidence is not robust and confounding factors (vasodilators background therapies) could impact on the findings. Future research is indicated to conduct larger, well-designed studies.

POS0741 REPORT FROM THE APS STUDY GROUP OF THE ITALIAN SOCIETY FOR RHEUMATOLOGY (SIR-APS) ON aPL NEGATIVIZATION

Background

The rate of antiphospholipid antibodies (aPL)negativization in antiphospholipid syndrome (APS) patients is uncertain, but it is estimated to be as high as 8%. aPL disappearance seems to be more frequent in patients positive for one single aPL test and appears to be related with the immunosuppressant/immunomodulatory treatment undertaken by the patient. Currently, a consensus definition of aPL negativization is lacking, as well as international recommendations on how to approach treatment in patients with a persistent aPL negative seroconversion.

Objectives

The aim of our work was to evaluate the clinical approach and the level of consensus among experts from the APS Study Group of the Italian Society for Rheumatology (SIR-APS) in different clinical scenario addressing aPL negativization and its definition.

Methods

Experts of SIR-APS were contacted using a survey methodology.

A structured survey was circulated among 30 experts.Up to 90% of the interviewed experts agreed on defining aPL negativization as the presence of two negative determinations, one year apart (90%).Almost ful lconsensus exist among experts in some clinical settings, including: a) the role of aPL negativitation in the management of a thrombotic event determined by concomitant presence of cardiovascular risk factors, both modifiable and not modifiable (90%): b) approach to young patients with triple aPL positivity who experienced pulmonary arterial thrombotic event and tested negative for aPL detection after five year of vitamin K antagonist (VKA) treatment (90%); c)the use of “extra criteria” aPL antibodies testing before pondering VKA suspension (93%).

Conclusion

Consensus is needed to support the management of patients with APS in areas where controlled data are missing. A substantial agreement exists among expert in defying aPL negativization as the presence of two negative determinations, one year apart. On the contrary, VKA suspension should be embraced with extreme caution when it comes to APS patients, particularly if they experienced arterial thrombotic events and/or tested positive for triple aPL. Nevertheless, VKA cessation might be considered when risk factors are carefully monitored/treated and the presence for “extra criteria” aPL is ruled out.

POS1457 ANALYSIS OF WORLDWIDE RHEUMATOLOGY POSTGRADUATE TRAINING CURRICULA: A MAPPING EXERCISE TO INFORM THE DEVELOPMENT OF EULAR STANDARDS FOR THE TRAINING OF EUROPEAN RHEUMATOLOGISTS

Background

Previous work has highlighted considerable heterogeneity in the organization of postgraduate rheumatology training programs. EULAR strives to harmonise rheumatology training across Europe with defined standards of key aspects of training including knowledge, skills and professional behaviors.

Objectives

To analyse existing documents on postgraduate training in rheumatology and other related specialties available within Europe and the rest of the world.

Methods

As most documents were unpublished, key documents on specialty training in Rheumatology and 28 related specialties were retrieved by hand-search. We started with the collection of documents developed by UEMS (Europe), ACGME (USA), CanMEDS (Canada) and RACP (Australia). Then we searched for specialty training documents developed by other international Boards and we also sent emails to the boards or associations if no document could be found in their websites. Finally, we retrieved national documents from European Countries with a structured rheumatology training process, translated them into English using DeepL/Google translate and, in case of doubt, liaised with native speakers familiar with the documents. The content of all the above documents (including information about the structure of each document) was extracted into a standardized data extraction sheet.

Results

133 documents were retrieved. UEMS, ACGME, CanMEDS documents were available for all the mapped specialties, while RACP documents were retrieved for only 18 specialties. No American or Canadian specialty board developed additional documents on training, while in Europe non-UEMS boards of 11 specialties did (Table 1). With regard to Rheumatology, 2 separate documents for adult and pediatric rheumatology training were available from UEMS and ACGME while one document on adult rheumatology training was retrieved for CanMEDS and RACP. Upon assessment of the content of these 133 documents, we observed that their organisation could be competence-based (48%), role-based (47%), or problem-based (5%). When focusing on Rheumatology, content was fairly similar across international curricula, but several differences emerged in national curricula. These were mainly related to national regulations (e.g. rheumatology training as part of internal medicine training) and a different definition of mandatory/optional competences. The number of listed competences in the rheumatology documents ranged from 18 to 196.

Conclusion

We collected and analysed documents on specialty training in Rheumatology and other related specialties across a broad set of international sources. Most documents followed a competence-based or role-based framework; similarities and differences in the content of Rheumatology documents were detected. This mapping exercise informed the EULAR Task Force on the development of standards for the training of European rheumatologists.

POS0898 SURGICAL MANAGEMENT OF DIGITAL ULCERS IN SYSTEMIC SCLEROSIS: A SYSTEMATIC LITERATURE REVIEW

Background

Management of digital ulcers (DUs) in systemic sclerosis (SSc) is a major clinical challenge. To date, systemic therapy is generally considered as the ‘standard of care’ for significant SSc-DUs. However, there is a strong rationale to develop local approaches to DUs, to avoid side effects from systemic therapies. World Scleroderma Foundation DU Working Group intends to develop practical, evidence-based recommendations for DU management including local, Surgical Treatment (L-ST).

Objectives

To summarize the literature on the safety and efficacy of L-ST for SSc-DUs.

Methods

A systematic literature review (SLR) was conducted up to May 2021. According to the PICO framework, eligibility criteria were defined and original research articles about surgical treatment of SSc DUs in adult patients were included. References were independently screened by 2 reviewers who assessed the full text of eligible articles and extracted data.

Results

Thirteen eligible articles out of 790 total publications were identified (Table 1). Due to the paucity of randomized controlled trials of surgical treatments for SSc-DU, we included retrospective studies and case series with at least 4 patients. Autologous fat (adipose tissue AT) grafting was the surgical modality mostly identified (7 studies of which 1 RCT and 6 prospective open label single arm). The healing rate (HR) with autologous fat grafting (4 studies) ranged from 66-100 %. In the RCT, two age and sex matched groups were included, adipose tissue (AT)group (n=25 pts) and sham procedure (SP) group (n=13), DU healing was reported in 23/25 in AT group versus 1/13 in the SP group in 8 wks, (p<0.0001), 12 pts in the SP group, received rescue AT injection, all of them healed after 8 wks. Three studies reported autologous adipose-derived stromal vascular fraction(SVF) grafting and the HR ranged from 32-60%, followed up to 12 months. Transient edema and paresthesia were reported in 2 studies, and amputation in 2 ulcers in 1 study, and no complications were reported in other studies. Surgical sympathectomy was reported in 3 studies, with a median healing rate of 81%. Bone marrow derived cell transplantation in a single study showed 87% healing rate over (4-24 wks). Two surgical studies (of direct microsurgical revascularization N=4, and microsurgical arteriolysis, N=6), showed 100% healing of ulcers, no complications reported.

Conclusion

Our SLR has identified several surgical modalities for SSc-DUs. L-STseemed generally effective and safe for DU healing, thus Significant methodological issues emerged including small numbers of pts, lack of comparator, failure to report confounders such as background therapies and variable follow up. Future research is warranted to rigorously investigate surgical interventions for Dus.

AB1181 THE BURDEN OF POST-SARS-COV2 VACCINE COMPLICATIONS AND NEWLY DIAGNOSED IMMUNE-MEDIATED INFLAMMATORY DISEASES

Background

Local and systemic reactions have been observed after all vaccines for SARS-CoV-2 but in the majority of cases, symptoms are mild and self-limiting. However, evidence on more severe clinical scenarios, requiring admission to hospital or referral to outpatient clinics after the administration of SARS-CoV-2 vaccines has accrued. This also includes newly diagnosed diseases, such as cardiovascular and immune-mediated inflammatory diseases (IMID).

Objectives

We aimed at quantifying the burden of post-vaccine hospital admissions/referrals and of newly diagnosed IMID.

Methods

Clinical records of patients referred to our Internal Medicine institution (both inpatients and outpatients) between February and June 2021 were retrospectively assessed. Subjects having received one or more doses of any of the EMA-approved SARS-CoV-2 vaccines within the previous 30 days were included. Subjects with a previous diagnosis of IMID were excluded.

Results

Our cohort included 99 patients, 45 females and 54 males, with a mean age of 64 years and a median of 3 comorbities (range 0-7). Eighty-eight patients (89%) required admission to the Internal Medicine ward while 11 were referred to the outpatient clinic. 68 (69%) of patients received the vaccine BNT162b2, 16 (16%) the ChAdOx1 nCoV-19, 9 (9%) the mRNA-1273 and 6 (6%) the Ad26.COV2.S. Twenty-seven (27%) subjects developed symptoms after the first vaccine dose with a mean latency of 2 days (median=0 indicating symptom onset on the day of the vaccine administration). Twenty-four (24%) subjects developed symptoms after the second dose with a mean latency of 4 days (median 1 day). All the other subjects did not develop symptoms within the week after the vaccine and were admitted for reasons apparently unrelated to vaccine administration. The number of presenting complaints ranged between 1 and 4 with 87% of subjects presenting with 1 or two coexisting complaints. Gastrointestinal manifestations were the most frequent being the presenting complaint in 31 (31%) of patients followed by severe fatigue/appetite loss in 19 (19%) of subjects, fever in 18 (18.2%) and neurological manifestation in 16 (16%) of subjects. A temporal and causal association with the SARS-CoV-2 vaccine was identified since all other known causes for these manifestations were ruled out. No in-hospital deaths were observed and 19 (19%) patients were diagnosed with a new onset IMID (Table 1). The clinical picture of these subjects was not significantly different from that of patients without a confirmed IMID and neither were demographic features. No association with the type of vaccine was observed.

Conclusion

Our data show that post-vaccine newly diagnosed IMID may represent a challenge in clinical practice and it seems that no demographic or clinical feature is able to predict their onset. A multidisciplinary cooperation and registry data are needed in order to reliably estimate and define the impact of SARS-CoV-2 vaccinations on new onset IMID.

POS0992 CLINICAL AND IMAGING FEATURES IN SPONDYLOARTHRITIS PATIENTS WITH AND WITHOUT HLA-B27 AND HLA-B51: A VALIDATION COHORT

Background

Despite being commonly expressed in the general population, the human leucocyte antigen (HLA)-B27 allele strongly increases the susceptibility to develop spondyloarthritis (SpA). Likewise, the association between the HLA-B51 allele and the development of Behçet’s disease is well documented. In a previous pilot study, we identified similarities and differences in patients with axial or peripheral SpA according to the presence of HLA-B51 only, HLA-B27 only or neither of the two.

Objectives

To investigate the clinical and imaging findings of SpA patients according to the absence or presence of HLA-B27 or HLA-B51 in an independent validation cohort.

Methods

We retrospectively analyzed patients with axial or peripheral SpA, according to the ASAS criteria, referring to our institution between 2020 and 2021. All patients had been tested for HLA-B alleles. Patients with HLA-B51 haplotype and fulfilling the criteria for Behçet’s disease were excluded.

Results

The independent validation cohort included 185 patients and was comparable to the original cohort of 236 patients with regard to age, gender, age at diagnosis and symptom duration. In line with the findings in the original cohort we observed that aphtous lesions were more prevalent in patients with HLA-B51 (p< 0.001) while inflammatory bowel disease was more prevalent in the double negative group (p=0.0006). Unlike the original cohort, patients of the validation cohort did not show a different prevalence of inflammatory back pain (IBP) at disease onset or in the disease course based on the HLA status. A sub-analysis by gender demonstrated a comparable prevalence of IBP in males and females within the 3 groups. As novel finding, we observed that enthesitis and psoriasis were significantly more prevalent in the double negative group compared to the B27 and B51 groups (p=0.004) and their prevalence did not differ when comparing B27 and B51 groups. With regard to imaging in patients with axial manifestations, in the original cohort we observed that sacroiliitis, assessed by X-ray or magnetic resonance imaging (MRI), were more prevalent in double negative and HLA-B27 patients, compared to HLA-B51 patients and the latter showed a significant negative association with sacroiliitis on imaging (OR 0.342 CI 0.189-0.619 p<0.0005). In this validation cohort we observed that the prevalence of sacroiliitis on X-ray was similar in the 3 groups while sacroiliitis on MRI scan was significantly more prevalent in the B27 group (81%) compared to the double negative (63%) and the B51 group (51%). A negative association between sacroiliitis on MRI and HLA-B51 but not double negative status was observed in the validation cohort (OR=0.23, 95% CI=0.07-0.8, p=0.02).

Conclusion

Our findings underscore the clinical and radiological heterogeneity of patients with SpA and HLA-B51 alone or neither HLA-B27 nor HLA-B51 compared to those with HLA-B27 only and underline the need to explore further this area by means of registry data with large real-life cohorts.

POS0900 SYSTEMIC PHARMACOLOGICAL TREATMENT OF DIGITAL ULCERS IN SYSTEMIC SCLEROSIS: A SYSTEMATIC LITERATURE REVIEW

Background

Digital ulcers (DU) are common in systemic sclerosis (SSc) and associated with reduced survival, high morbidity and poor quality of life. Recommendations have previously been proposed for DU management yet there remains significant unmet patient need. Therefore the World Scleroderma Foundation DU Working Group intends to develop practical evidence based recommendations for DU management.

Objectives

To summarise data on efficacy and safety of systemic treatments for SSc DU.

Methods

A systematic literature review to May 2021 was performed. PubMed, MEDLINE, Embase, Web of Science, Cochrane Library, Emcare (OVID) and Academic Search Premier databases were searched for original studies on adult patients with SSc DU treated with systemic pharmacological treatment. Based on the PICO framework, eligibility criteria were defined and references were independently screened by two reviewers. Reviewers independently assessed the full text of eligible articles. Owing to interstudy heterogeneity narrative summaries were used to present data.

Results

The search strategy identified 1271 references of which 45 eligible articles were included. Seventeen studies were randomised placebo controlled trials (RCT) pertaining to PDE5 antagonists (PDE5i) (n=3), endothelin receptor antagonists (ERA) (n=3), prostanoids (n=7), antiplatelet agents (n=1) and other (n=3) (Table 1). No head to head RCT was retrieved. All other studies were observational studies (OBS). Studies were highly heterogeneous with application of differing definition of DU, variable study eligibility criteria, clinical endpoints and follow up periods. This limited the calculation of effect size and comparison across studies.

DU: digital ulcers IV: intravenous SSc: systemic sclerosis

Several RCT found improved DU healing with treatment: two with PDE5i, one with iloprost and one showed improved DU healing and prevention with atorvastatin. Two RCT demonstrated effective prevention of new DU with bosentan. OBS studies with a total of 621 patients showed variable improvements in the healing of DU with CCB, PDE5i, ERA, statins, N-acetylcysteine, prostanoids and ketanserin and prevention of new DU with ERA.

Regarding safety, all treatments were generally tolerated with few serious adverse events. Treatment was ceased in 6.25-17.5% of patients in RCT due to treatment related side effects.

Conclusion

Despite several studies assessing the efficacy and safety of systemic pharmacological treatment of SSc DU, it is not possible to draw solid conclusions due to study heterogeneity. Small RCT have shown treatment benefit with PDE5i, iloprost and atorvastatin. Large studies demonstrated effective prevention of new DU with bosentan. Our results highlight the urgent need for improved clinical trial design to generate more robust evidence and novel therapies to guide the management SSc DU.

POS0895 THE ROLE OF SURGERY IN THE ESOPHAGEAL INVOLVEMENT IN SYSTEMIC SCLEROSIS: A SYSTEMATIC LITERATURE REVIEW

Background

Among gastrointestinal (GI) manifestations in Systemic Sclerosis (SSc) one of the predominant and challenging problems is gastroesophageal reflux disease (GERD), which occurs in ~75% of patients. Although proton pump inhibitors are useful, they are ineffective in 40% of cases with chronic use at high doses, against the background of long-term risks (e.g., cardiovascular disease and infections) which have been identified in the general population. Surgery might be an option following failure of medical therapy but currently, there is no consensus regarding the optimal surgical procedure for refractory GERD in SSc.

Objectives

To evaluate, among the surgical approaches to GERD, the feasibility of fundoplication (FP) with regards to its safety, efficacy, indications, and timing.

Methods

Four research questions based on the PICO framework were developed to guide the systematic literature review that was conducted up to 22 December 2021. The search and performed across different databases including PubMed, MEDLINE (OVID), EMBASE, Cochrane Library, Web of Science, Google Scholar, Emcare and Academic Search Premier. References were independently screened by two reviewers (PMC and AA) who also independently assessed the full text of eligible articles, and extracted data. Due to heterogeneity of retrieved studies, narrative summaries are used to present the data.

Results

The search yielded 916 papers of which 30 were eligible for full text review. In these studies, out of 2919 clinically heterogeneous patients, 348 SSc patients were identified (mostly female, mean age 52.7 years). Out of these 348, only 257 underwent anti-reflux surgical procedure and were included in the analysis. Most of the studies were conducted in surgical settings and relevant rheumatological data were largely missing. Refractory GERD symptoms, were the commonest indication for surgery, with post-operative dysphagia being the most frequent complication. In 18 studies, FP was effective, whereas 4 studies had equivocal findings and in 5 a lack of efficacy was reported. The Collis-Nissen FP was the most popular procedure overall as well as in earlier studies, followed by Nissen FP, and Dor FP in relatively more recent studies, reflecting the change in surgical strategy over time. The data extracted shows also an acceptable rate of mortality and morbidity related to surgery, and heterogeneous outcome measures were used hampering any comparison of the studies (Table 1). Due to the heterogeneity of the data, it was not possible to separate the mortality and morbidity rate of SSc patients from the rest of the population.

Conclusion

Our SLR has highlighted that the surgical management of GERD in SSc patients is still highly challenging since the available evidence is scarce and of poor quality. Among the surgical approaches to the problem of GERD, overall FP seems a safe and effective procedure in SSc. Transient post-operative dysphagia was noted in many studies, particularly related with the posterior FP. In the future, it will be necessary to develop minimal requirement to conduct surgical studies in SSc as well as to design studies aimed at defining the clinical criteria for referral to surgery. Indeed, the right timing for surgery and the best surgical procedure in SSc still remains an unmet need.

Clinical Delphi on aPLnegativization: report from the from the APS Study Group of the Italian Society for Rheumatology (SIR-APS)

The rate of antiphospholipid antibodies (aPL) negativization in antiphospholipid syndrome (APS) patients is uncertain, but it is estimated to be as high as 8%. Currently, a consensus definition of aPL negativization is lacking, as well as international recommendations on how to approach treatment in patients with a persistent aPL negative seroconversion. Evaluate the clinical approach and level of consensus among experts from the APS Study Group of the Italian Society for Rheumatology (SIR-APS) in different clinical scenario. Experts of SIR-APS were contacted using a survey methodology. A structured survey was circulated among 30 experts.Up to 90% of the interviewed experts agreed on defining aPL negativization as the presence of two negative determinations, one year apart (90%).Almost full consensus exist among experts in some clinical settings, including: a) the role of aPL negativization in the management of a thrombotic event determined by concomitant presence of cardiovascular risk factors, both modifiable and not modifiable (90%); b) approach to young patients with triple aPL positivity who experienced pulmonary arterial thrombotic event and tested negative for aPL detection after five year of vitamin K antagonist (VKA) treatment (90%); c)the use of "extra criteria" aPL antibodies testing before pondering VKA suspension (93%). A substantial agreement exists among expert on how to define aPL negativization. VKA suspension should be embraced with extreme caution, particularly in case of previous thrombotic events and/or triple aPL positivity. Nevertheless, VKA cessation might be considered when risk factors are carefully monitored/treated and the presence for "extra criteria" is ruled out.

Pathogenesis of rheumatoid arthritis: one year in review 2022

The mechanisms underlying the pathogenesis of rheumatoid arthritis (RA) involve different components of the immune system. In subjects with genetic predisposition to develop RA, a tight interaction between cells and mediators of the innate and adaptive immune system leads to the amplification and perpetuation of inflammation and tissue remodelling. The research carried out in the last year in the field of RA has improved the current knowledge on the pathogenesis of the disease, and is potentially useful to develop new therapeutic approaches. Thus, in this review we provide an overview on the new insights into RA pathogenesis, resulting from a literature search of the data published in the last year.

EULAR points to consider for minimal reporting requirements in synovial tissue research in rheumatology

BACKGROUND

Synovial tissue research has become widely developed in several rheumatology centres, however, large discrepancies exist in the way synovial tissue is handled and, more specifically, how data pertaining to biopsy procedure, quality check and experimental results are reported in the literature. This heterogeneity hampers the progress of research in this rapidly expanding field. In that context, under the umbrella of European Alliance of Associations for Rheumatology, we aimed at proposing points to consider (PtC) for minimal reporting requirements in synovial tissue research.

METHODS

Twenty-five members from 10 countries across Europe and USA met virtually to define the key areas needing evaluation and formulating the research questions to inform a systematic literature review (SLR). The results were presented during a second virtual meeting where PtC were formulated and agreed.

RESULTS

Study design, biopsy procedures, tissue handling, tissue quality control and tissue outcomes (imaging, DNA/RNA analysis and disaggregation) were identified as important aspects for the quality of synovial tissue research. The SLR interrogated four databases, retrieved 7654 abstracts and included 26 manuscripts. Three OPs and nine PtC were formulated covering the following areas: description of biopsy procedure, overarching clinical design, patient characteristics, tissue handling and processing, quality control, histopathology, transcriptomic analyses and single-cell technologies.

CONCLUSIONS

These PtC provide guidance on how research involving synovial tissue should be reported to ensure a better evaluation of results by readers, reviewers and the broader scientific community. We anticipate that these PtC will enable the field to progress in a robust and transparent manner over the coming years.

EULAR recommendations for the management and vaccination of people with rheumatic and musculoskeletal diseases in the context of SARS-CoV-2: the November 2021 update

The first EULAR provisional recommendations on the management of rheumatic and musculoskeletal diseases (RMDs) in the context of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), largely based on expert opinion, were published in June 2020. Since then, an unprecedented number of clinical studies have accrued in the literature. Several SARS-CoV-2 vaccines have been approved for population-wide vaccination programmes in EULAR-affiliated countries. Studies regarding vaccination of patients with (inflammatory) RMDs have released their first results or are underway.EULAR found it opportune to carefully review to what extent the initially consensus expert recommendations stood the test of time, by challenging them with the recently accumulated body of scientific evidence, and by incorporating evidence-based advice on SARS-CoV-2 vaccination. EULAR started a formal (first) update in January 2021, performed a systematic literature review according to EULAR's standard operating procedures and completed a set of updated overarching principles and recommendations in July 2021. Two points to consider were added in November 2021, because of recent developments pertaining to additional vaccination doses.

Twelve-month outcomes in overweight/obese users with mental disorders following a multi-element treatment including diet, physical activity, and positive thinking: The real-world "An Apple a Day" controlled trial

The present study aimed to evaluate the 12-month effectiveness of a real-world weight loss transdiagnostic intervention in overweight/obese participants affected by mental disorders under psychopharmacological treatment. We conducted a real-world, controlled, pragmatic outpatient trial. We allocated 58 overweight/obese adults under psychopharmacological treatment from a mental health outpatient unit and 48 overweight/obese adults from a cardiovascular prevention outpatient unit, and assigned them to an intervention or treatment usual as condition (TAU) enriched by life-style advice. Participants in both intervention groups took part in a diet programme (the modified OMNIHeart dietary protocol) and monitoring of regular aerobic activity. A brief group programme ("An Apple a Day" Metacognitive Training, Apple-MCT) was added in the intervention group of participants affected by mental disorders. The primary outcome was weight loss. Secondary outcomes included anthropometric, clinical, and metabolic variables. Psychopathology and health-related quality of life were also evaluated in the psychiatric sample. At 12 months, both intervention groups showed a more marked mean decrease in weight (6.7 kg, SD: 3.57) than the TAU group (0.32 kg, SD: 1.96), and a statistically significant improvement in metabolic variables compared with the control groups. Furthermore, the participants affected by mental disorders included in the intervention group reported improved health-related quality of life. Our findings suggest the need to implement integrated interventions based on a dietary protocol, physical activity, and modification of cognitive style in overweight/obese users with mental disorders.
