Management of pregnancy in autoimmune rheumatic diseases: maternal disease course, gestational and neonatal outcomes and use of medications in the prospectiveItalian P-RHEUM.it study

OBJECTIVES

To investigate pregnancy outcomes in women with autoimmune rheumatic diseases (ARD) in the Italian prospective cohort study P-RHEUM.it.

METHODS

Pregnant women with different ARD were enrolled for up to 20 gestational weeks in 29 Rheumatology Centres for 5 years (2018-2023). Maternal and infant information were collected in a web-based database.

RESULTS

We analysed 866 pregnancies in 851 patients (systemic lupus erythematosus was the most represented disease, 19.6%). Maternal disease flares were observed in 135 (15.6%) pregnancies. 53 (6.1%) pregnancies were induced by assisted reproduction techniques, 61 (7%) ended in miscarriage and 11 (1.3%) underwent elective termination. Obstetrical complications occurred in 261 (30.1%) pregnancies, including 2.3% pre-eclampsia. Two cases of congenital heart block were observed out of 157 pregnancies (1.3%) with anti-Ro/SSA. Regarding treatments, 244 (28.2%) pregnancies were treated with glucocorticoids, 388 (44.8%) with hydroxychloroquine, 85 (9.8%) with conventional synthetic disease-modifying anti-rheumatic drugs and 122 (14.1%) with biological disease-modifying anti-rheumatic drugs. Live births were 794 (91.7%), mostly at term (84.9%); four perinatal deaths (0.5%) occurred. Among 790 newborns, 31 (3.9%) were small-for-gestational-age and 169 (21.4%) had perinatal complications. Exclusive maternal breast feeding was received by 404 (46.7%) neonates. The Edinburgh Postnatal Depression Scale was compiled by 414 women (52.4%); 89 (21.5%) scored positive for emotional distress.

CONCLUSIONS

Multiple factors including preconception counselling and treat-to-target with pregnancy-compatible medications may have contributed to mitigate disease-related risk factors, yielding limited disease flares, good pregnancy outcomes and frequency of complications which were similar to the Italian general obstetric population. Disease-specific issues need to be further addressed to plan preventative measures.

New onset sarcoidosis following biologic treatment in patients with seronegative inflammatory arthritis: A case series and systematic literature review

OBJECTIVE

To report cases of new onset sarcoidosis upon biologic (bDMARDs) treatment administration in patients with seronegative inflammatory arthritis in a real-life cohort, alongside a systematic literature review (SLR) on this topic.

METHODS

We performed a retrospective analysis on clinical records of patients with seronegative arthritis followed up in a monocentric cohort who underwent bDMARDs treatment due to the underlying rheumatic disease and described any newly diagnosed sarcoidosis in this cohort. Only ascertained cases with available radiological and/or histological documentation were considered. A SLR on new-onset sarcoidosis in seronegative arthritis receiving bDMARDs was performed across MEDLINE (through PubMed), Scopus and Ovid (Cochrane, Embase) electronic databases using appropriate strings.

RESULTS

In our cohort, 4 new-onset cases of sarcoidosis were reported among patients with seronegative inflammatory arthritis receiving biologics. Three out of 4 patients were receiving anti-tumor necrosis factor alpha (TNFα) while 1 patient was on secukinumab (anti-IL17A) prior to sarcoidosis onset. The SLR disclosed 46 new-onset sarcoidosis cases upon biological treatment for seronegative arthritis, of whom 43 occurred during treatment with anti-TNFα, while 3 during anti-IL-17A therapy. In our cohort as well as in the majority of cases reported in the SLR, sarcoidosis presented with lymph nodal and lung involvement and displayed a benign course with spontaneous resolution in about 1 fourth of the cases.

CONCLUSION

The use of biologics may relate to the onset of sarcoidosis; hence, clinicians must remain aware of the potential occurrence or reactivation of sarcoidosis when starting biologic treatment in patients with inflammatory arthritis, performing adequate patient assessment and surveillance. Since TNFα inhibitors may represent a therapeutic option for sarcoidosis, further evaluation on larger cohorts is needed to investigate any causal link with the development of sarcoidosis.

COVID-19 prognosis in systemic lupus erythematosus compared with rheumatoid arthritis and spondyloarthritis: results from the CONTROL-19 Study by the Italian Society for Rheumatology

INTRODUCTION

Data concerning SARS-CoV-2 in patients affected by SLE are contradicting.The aim of this study was to investigate disease-related differences in COVID-19 prognosis of patients affected by rheumatic diseases before vaccination; we tested the hypothesis that patients with SLE may have a different outcome compared with those with rheumatoid arthritis (RA) or spondyloarthritis (SPA).

METHODS

We analysed data from the national CONTROL-19 Database with a retrospective, observational design, including rheumatic patients affected by COVID-19. The principal outcome measure was hospitalisation with death or mechanical ventilation. Differences between SLE, RA and SPA were analysed by univariable and multivariable logistic regression models.

RESULTS

We included 103 patients with SLE (88.2% female, mean age 48.9 years, 50.4% active disease), 524 patients with RA (74.4% female, mean age 60.6 years, 59.7% active disease) and 486 patients with SPA (58.1% female, mean age 53.2 years, 58% active disease).Outcome prevalence was not different between patients with SLE and those with RA (SLE 24.5%, RA 25.6%), while patients with SPA showed a more favourable outcome compared with those with SLE (SPA 15.9%); data from the multivariable analysis confirmed this result.In SLE, age >65 years (OR 17.3, CI 5.51 to 63.16, p<0.001), hypertension (OR 6.2, CI 2.37 to 17.04, p<0.001) and prednisone (PDN) use (OR 3.8, CI 1.43 to 11.39, p=0.01) were associated with severe outcomes, whereas hydroxychloroquine use was found to be protective (OR 0.3, CI 0.14 to 0.91, p=0.03).

CONCLUSION

Our data suggest that patients with SLE and RA do not show a different COVID-19 outcome, while patients with SPA have a more favourable disease course compared with those with SLE. Risk of hospitalisation with ventilation or death was associated with age >65 years, hypertension and PDN use in patients with SLE.

Characteristics associated with poor COVID-19 outcomes in people with psoriasis, psoriatic arthritis and axial spondyloarthritis: data from the COVID-19 PsoProtect and Global Rheumatology Alliance physician-reported registries

OBJECTIVES

To investigate factors associated with severe COVID-19 in people with psoriasis (PsO), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA).

METHODS

Demographic data, clinical characteristics and COVID-19 outcome severity of adults with PsO, PsA and axSpA were obtained from two international physician-reported registries. A three-point ordinal COVID-19 severity scale was defined: no hospitalisation, hospitalisation (and no death) and death. ORs were estimated using multivariable ordinal logistic regression.

RESULTS

Of 5045 cases, 18.3% had PsO, 45.5% PsA and 36.3% axSpA. Most (83.6%) were not hospitalised, 14.6% were hospitalised and 1.8% died. Older age was non-linearly associated with COVID-19 severity. Male sex (OR 1.54, 95% CI 1.30 to 1.83), cardiovascular, respiratory, renal, metabolic and cancer comorbidities (ORs 1.25-2.89), moderate/high disease activity and/or glucocorticoid use (ORs 1.39-2.23, vs remission/low disease activity and no glucocorticoids) were associated with increased odds of severe COVID-19. Later pandemic time periods (ORs 0.42-0.52, vs until 15 June 2020), PsO (OR 0.49, 95% CI 0.37 to 0.65, vs PsA) and baseline exposure to TNFi, IL17i and IL-23i/IL-12+23i (OR 0.57, 95% CI 0.44 to 0.73; OR 0.62, 95% CI 0.45 to 0.87; OR 0.67, 95% CI 0.45 to 0.98; respectively; vs no disease-modifying antirheumatic drug) were associated with reduced odds of severe COVID-19.

CONCLUSION

Older age, male sex, comorbidity burden, higher disease activity and glucocorticoid intake were associated with more severe COVID-19. Later pandemic time periods, PsO and exposure to TNFi, IL17i and IL-23i/IL-12+23i were associated with less severe COVID-19. These findings will enable risk stratification and inform management decisions for patients with PsO, PsA and axSpA during COVID-19 waves or similar future respiratory pandemics.

A real-world economic analysis of biologic therapies for psoriatic arthritis in Italy: results of the CHRONOS observational longitudinal study

BACKGROUND

Psoriatic arthritis (PsA) is a chronic, immune-mediated, spondyloarthropathy characterised by musculoskeletal signs and symptoms with associated joint pain and tenderness. The average worldwide PsA prevalence is 133/100,000, while in the Italian population is 90-420/100,000. Traditionally, nonsteroidal anti-inflammatory drugs, glucocorticoid, and disease-modifying antirheumatic drugs have been used in the treatment of PsA. However, for those patients who are not adequately controlled with conventional therapies, the new biologics compounds represent a valid option. Biologic therapies have been shown to be more effective but also more expensive than conventional systemic treatments. Based on the CHRONOS study, the economic analyses presented in this paper aim to assess the annualised direct costs and the cost-per-responder of biologics in a real-world context assuming the Italian National Health System perspective.

METHODS

The economic assessments were carried out on the overall cohort of patients, and on the tumour necrosis factor alpha inhibitors (TNFi) and the secukinumab subgroup, the most prescribed biologic therapies within the CHRONOS study.

RESULTS

The annual economic impact of PsA in the overall group was €12,622, €11,725 in the secukinumab subgroup, and €12,791 in the TNFi subgroup. Biologics absorbed the main expenditure costs in the treatment of PsA accounting for about the 93% of total costs. At 6 months, secukinumab performed better in all the considered outcomes: cost-per-responder according to EULAR DAS28 and ACR50 response criteria were €12,661- €28,975, respectively, while they were €13,356 - €33,368 in the overall cohort and €13,138 - €35,166 in the TNFi subgroup. At 12 months secukinumab remained the subgroup with the lowest cost-per-responder ratio in EULAR DAS28 and ACR50 response criteria, while TNFi subgroup was the lowest one considered the ACR20.

CONCLUSION

Despite some potential methodological limitations, our cost-per-response analysis provides physicians and payers additional insights which can complement the traditional risk-benefit profile assessment and drive treatment decisions.

Development and implementation of the AIDA International Registry for patients with Behçet's disease

Purpose of the present paper is to point out the design, development and deployment of the AutoInflammatory Disease Alliance (AIDA) International Registry dedicated to pediatric and adult patients with Behçet's disease (BD). The Registry is a clinical physician-driven non-population- and electronic-based instrument implemented for the retrospective and prospective collection of real-life data about demographics, clinical, therapeutic, laboratory, instrumental and socioeconomic information from BD patients; the Registry is based on the Research Electronic Data Capture (REDCap) tool, which is thought to collect standardised information for clinical real-life research, and has been realised to change over time according to future scientific acquisitions and potentially communicate with other existing and future Registries dedicated to BD. Starting from January 31st, 2021, to February 7th, 2022, 110 centres from 23 countries in 4 continents have been involved. Fifty-four of these have already obtained the approval from their local Ethics Committees. Currently, the platform counts 290 users (111 Principal Investigators, 175 Site Investigators, 2 Lead Investigators, and 2 data managers). The Registry collects baseline and follow-up data using 5993 fields organised into 16 instruments, including patient's demographics, history, clinical manifestations and symptoms, trigger/risk factors, therapies and healthcare access. The development of the AIDA International Registry for BD patients will facilitate the collection of standardised data leading to real-world evidence, enabling international multicentre collaborative research through data sharing, international consultation, dissemination of knowledge, inclusion of patients and families, and ultimately optimisation of scientific efforts and implementation of standardised care.Trial registration NCT05200715 in 21/01/2022.

Real-world evidence of biologic treatments in psoriatic arthritis in Italy: results of the CHRONOS (EffeCtiveness of biologic treatments for psoriatic artHRitis in Italy: an ObservatioNal lOngitudinal Study of real-life clinical practice) observational longitudinal study

Background

Biologics have demonstrated efficacy in PsA in randomized clinical trials. More evidence is needed on their effectiveness under real clinical practice conditions. The aim of the present work is to provide real-world evidence of the effectiveness of biologics for PsA in the daily clinical practice.

Methods

CHRONOS was a multicenter, non-interventional, cohort study conducted in 20 Italian hospital rheumatology clinics.

Results

399 patients were eligible (56.9% females, mean (SD) age: 52.4 (11.6) years). The mean (SD) duration of PsA and psoriasis was 7.2 (6.9) and 15.3 (12.2) years, respectively. The mean (SD) duration of the biologic treatment under analysis was 18.6 (6.5) months. The most frequently prescribed biologic was secukinumab (40.4%), followed by adalimumab (17.8%) and etanercept (16.5%). The proportion of overall responders according to EULAR DAS28 criteria was 71.8% (95% CI: 66.7–76.8%) out of 308 patients at 6 months and 68.0% (95% CI: 62.7–73.3%) out of 297 patients at 1 year. Overall, ACR20/50/70 responses at 6 months were 41.2% (80/194), 29.4% (57/194), 17.1% (34/199) and at 1-year were 34.9% (66/189), 26.7% (51/191), 18.4% (36/196), respectively. Secondary outcome measures improved rapidly already at 6 months: mean (SD) PASI, available for 87 patients, decreased from 3.2 (5.1) to 0.6 (1.3), the proportion of patients with dactylitis from 23.6% (35/148) to 3.5% (5/142) and those with enthesitis from 33.3% (49/147) to 9.0% (12/133).

Conclusions

The CHRONOS study provides real-world evidence of the effectiveness of biologics in PsA in the Italian rheumatological practice, confirming the efficacy reported in RCTs across various outcome measures.

Development and Implementation of the AIDA International Registry for Patients With VEXAS Syndrome

Objective

The aim of this paper is to present the AutoInflammatory Disease Alliance (AIDA) international Registry dedicated to Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic (VEXAS) syndrome, describing its design, construction, and modalities of dissemination.

Methods

This Registry is a clinical, physician-driven, population- and electronic-based instrument designed for the retrospective and prospective collection of real-life data. Data gathering is based on the Research Electronic Data Capture (REDCap) tool and is intended to obtain real-world evidence for daily patients' management. The Registry may potentially communicate with other on-line tools dedicated to VEXAS syndrome, thus enhancing international collaboration and data sharing for research purposes. The Registry is practical enough to be easily modified to meet future needs regarding VEXAS syndrome.

Results

To date (April 22^nd, 2022), 113 Centers from 23 Countries in 4 continents have been involved; 324 users (114 Principal Investigators, 205 Site Investigators, 2 Lead Investigators, and 3 data managers) are currently able to access the registry for data entry (or data sharing) and collection. The Registry includes 4,952 fields organized into 18 instruments designed to fully describe patient's details about demographics, clinical manifestations, symptoms, histologic details about skin and bone marrow biopsies and aspirate, laboratory features, complications, comorbidities, therapies, and healthcare access.

Conclusion

This international Registry for patients with VEXAS syndrome will allow the achievement of a comprehensive knowledge about this new disease, with the final goal to obtain real-world evidence for daily clinical practice, especially in relation to the comprehension of this disease about the natural history and the possible therapeutic approaches.

AB0224 JAK-INHIBITORS ATTAIN A RAPID AND PERSISTENT EFFECTIVENESS ON SEVERAL PATIENT-REPORTED OUTCOMES IN LONG-STANDING RHEUMATOID ARTHRITIS

Background

Janus kinase inhibitors (JAKi) are efficacious drugs for the control of disease activity in rheumatoid arthritis (RA). The effect on patient-reported outcomes (PROs) has been shown in randomized clinical trials, but is still largely unknown in real-life scenarios.

Objectives

To assess the time to onset and magnitude of improvement across a number of different PROs in patients with RA treated with JAKi.

Methods

Patients were selected from centres involved in the LORHEN Registry. Patients with a diagnosis of RA initiating a JAKi (Baricitinib or Tofacitinib) between May 2019 and February 2020 were clinically assessed at baseline, 8 weeks and 16 weeks with DAS28 and SDAI. PROs were collected at baseline, 2 weeks, 4 weeks, 8 weeks and 16 weeks from JAKi initiation. The PROs assessed at each timepoint were: Patient Global Assessment (PGA), General Health (GH), 0-100 mm visual analogue scale (VAS)-pain, VAS-fatigue, Health Assessment Questionnaire (HAQ), The Clinical Arthritis Activity (PRO-CLARA) questionnaire.

Results

Thirty-eight patients (female 76%, mean age 57±15) were enrolled for a total of 152 visits for PROs assessments. Patients had received a median of 2 (IQR 1;3) previous conventional synthetic DMARDs (csDMARD) and a median of 2 (0;3) biological DMARDs. Mean disease duration at time of JAKi initiation was 10±9.5 years. JAKi was prescribed as combination therapy with a csDMARD in 20 (53%), concomitant glucocorticoids (GC) in 28 (73%) patients, at a mean dose of 6±2 mg/day. Twenty-one (55) patients were on regular analgesics. DAS28-ESR reduced from 4.5±0.9 at baseline to 2.6±0.9 at 8 weeks (p<0.001). DAS28-ESR remained stable between 8 and 16 weeks (mean values 2.3±0.1; p=0.17). Similarly, DAS28-CRP reduced from 4.1±0.8 to 2.1±0.6 at 8 weeks (p<0.0001). Between 8 and 16 weeks there was a further significant reduction of DAS28-CRP under the effect of JAKi treatment to a mean value of 1.4±0.5 (p<0.0001). SDAI reduced over the period of observation from 19±8 to 6±5 at 8 weeks (p<0.0001), and to 4±3 at 16 weeks (0.03). By week 8 the intake of concomitant GC reduced to 28% of patients (p=0.0001), and of analgesics to 2% of patients (p<0.0001).

By two weeks, all PROs had a significant reduction compared to baseline (Figure 1). For PGA, VAS-pain, VAS-fatigue a further significant reduction was observed by week 4 to then stabilize between week 8 and 16. GH and HAQ had a significant reduction by week 2 and remained stable thereafter. All PROs were significantly lower during all time-points compared to baseline. The PRO-CLARA Road score to assess physical function significantly improved starting from week 2 from a score of 4±2 to 2±2 at the end of follow-up. The PRO-CLARA self-administered tender joint count was stable at week 2 (mean score 4±2) but recorded an improvement from week 4 onwards (p<0.03).

Figure 1.

Improvement of patient-reported outcomes over the period of observation

Conclusion

Treatment with JAKi ensures a very rapid and persistent improvement of several PROs, including pain, fatigue and physical function, as early as 2 weeks treatment even in patients with long-standing RA treated with several lines of previous DMARDs.

POS0634 SAFETY PROFILE OF b/tsDMARD IN RHEUMATOID ARTHRITIS PATIENTS WITH IMPAIRED GLOMERULAR FILTRATION RATE. AN ANALYSIS FROM THE GISEA REGISTRY

Background

In real-life setting, a greater number of elderly rheumatoid arthritis (RA) patients with impaired glomerular filtration rate (GFR) needs treatment with biologic or target synthetic disease-modifying anti-rheumatic drugs (b/tsDMARD) to achieve disease control and reduce NSAIDs intake. Long-term observational data from the real-life on the use of b/tsDMARD in these patients are scarce.

Objectives

The aim of this study was to evaluate the retention rate of b/tsDMARD in RA patients with impaired GFR in real-life setting.

Methods

Data of RA patients treated with at least one b/tsDMARD were retrospectively analyzed form the national Italian GISEA registry from January 2016 to December 2021. Estimated-GFR (eGFR) was calculated with the Cockcroft-Gault equation at the time of any b/tsDMARD prescription. For the purpose of this study, patients were divided in two groups, patients with impaired GFR (eGFR ≤60) and patients with normal GFR (eGFR >60). The retention rate was calculated by the Kaplan-Meier method and compared between these two groups by a log-rank test.

Results

The study population included 2443 treatment-line with b/tsDMARD from 1888 patients (female 80.4%, age 57±12 years, mean baseline CDAI 17±12, FR/ACPA+ 69.5%) who started a new b/tsDMARD. Disease characteristics are shown in Table 1. 288 treatments with b/tsDMARD were started in patients with impaired eGFR and 2155 in patients with normal eGFR. Compared to patients with eGFR >60, patients with eGFR ≤60 showed higher HAQ-DI (1.3±0.8 vs 1±0.8, p<0.001) at the start of b/tsDMARD treatment. Glucocorticoids were more prescribed in patients with impaired eGFR (80.2% vs 72.8%, p<0.01), while csDMARDs were more prescribed in association with b/tsDMARD in patients with normal eGFR (83.1% vs 76.4%, p<0.01). Of note, CTLA4-Ig treatment was more prescribed in patients with impaired eGFR (26% vs 17.1%, p<0.05), while no difference in b/tsDMARD prescription was observed for other mechanism of actions. Drug survival was similar between RA patients with impaired eGFR [58.2%, mean survival time 35 months (CI95% 31-39)]and RA patients with normal eGFR [55%, mean survival time 34.4 months (CI95% 33-36), log rank: 0.88] (Figure 1). Cox regression model adjusted for age, sex and b/tsDMARD showed no impact of eGFR on drug survival [HR: 0.9 (CI95%: 0.7-1.2).

Conclusion

Our data show that impaired eGFR seems to not influence the persistence of b/tsDMARD treatment in RA patients.

Early Spondyloarthritis Clinic: Organizational Improvements in the Patient Journey

Spondyloarthritis are chronic inflammatory diseases affecting spine, peripheral joints and enthesis, as well as extra-articular sites (bowel, eyes, skin). Diagnosis of spondyloarthritis often is slow and requires a multidisciplinary approach. The “Early SpA Clinic” project aimed at improving the patient care and journeys, by solving some organizational issues existing in Rheumatology Clinics. The “Early SpA Clinic” involved 19 Italian Rheumatology Centers using in-depth organizational analyses to identify areas for improvement. From the results of the analyses, some organizational solutions were suggested, and their impact measured at the end of the project through specific KPI. With the implementation of the suggested organizational solutions, Centers achieved relevant results, positively impacting on all the phases of the patient journey: decrease in waiting lists (−23%) and in the time length to transit the Center (−22%), increase in the percentage of new diagnoses (+20%), in the saturation of outpatient clinic capacity (+16%), and in the patient satisfaction (+4%). Centers involved in the “Early SpA Clinic” implemented several organizational actions based on an overall assessment of their activities and on solutions that required no additional resources. Overall, the Centers achieved the “Early SpA Clinic” objectives in terms of better management of resources, personnel, spaces, equipment, in relation to the volumes of patients.

OP0249 CHARACTERISTICS ASSOCIATED WITH POOR COVID-19 OUTCOMES IN PEOPLE WITH PSORIASIS AND SPONDYLOARTHRITIS: DATA FROM THE COVID-19 PsoProtect AND GLOBAL RHEUMATOLOGY ALLIANCE PHYSICIAN-REPORTED REGISTRIES

Background

Some factors associated with severe COVID-19 outcomes have been identified in patients with psoriasis (PsO) and inflammatory/autoimmune rheumatic diseases, namely older age, male sex, comorbidity burden, higher disease activity, and certain medications such as rituximab. However, information about specificities of patients with PsO, psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA), including disease modifying anti-rheumatic drugs (DMARDs) specifically licensed for these conditions, such as IL-17 inhibitors (IL-17i), IL-23/IL-12 + 23 inhibitors (IL-23/IL-12 + 23i), and apremilast, is lacking.

Objectives

To determine characteristics associated with severe COVID-19 outcomes in people with PsO, PsA and axSpA.

Methods

This study was a pooled analysis of data from two physician-reported registries: the Psoriasis Patient Registry for Outcomes, Therapy and Epidemiology of COVID-19 Infection (PsoProtect), comprising patients with PsO/PsA, and the COVID-19 Global Rheumatology Alliance (GRA) registry, comprising patients with PsA/axSpA. Data from the beginning of the pandemic up to 25 October, 2021 were included. An ordinal severity outcome was defined as: 1) not hospitalised, 2) hospitalised without death, and 3) death. A multivariable ordinal logistic regression model was constructed to assess the relationship between COVID-19 severity and demographic characteristics (age, sex, time period of infection), comorbidities (hypertension, other cardiovascular disease [CVD], chronic obstructive lung disease [COPD], asthma, other chronic lung disease, chronic kidney disease, cancer, smoking, obesity, diabetes mellitus [DM]), rheumatic/skin disease (PsO, PsA, axSpA), physician-reported disease activity, and medication exposure (methotrexate, leflunomide, sulfasalazine, TNFi, IL17i, IL-23/IL-12 + 23i, Janus kinase inhibitors (JAKi), apremilast, glucocorticoids [GC] and NSAIDs). Age-adjustment was performed employing four-knot restricted cubic splines. Country-adjustment was performed using random effects.

Results

A total of 5008 individuals with PsO (n=921), PsA (n=2263) and axSpA (n=1824) were included. Mean age was 50 years (SD 13.5) and 51.8% were male. Hospitalisation (without death) was observed in 14.6% of cases and 1.8% died. In the multivariable model, the following variables were associated with severe COVID-19 outcomes: older age (Figure 1), male sex (OR 1.53, 95%CI 1.29-1.82), CVD (hypertension alone: 1.26, 1.02-1.56; other CVD alone: 1.89, 1.22-2.94; vs no hypertension and no other CVD), COPD or asthma (1.75, 1.32-2.32), other lung disease (2.56, 1.66-3.97), chronic kidney disease (2.32, 1.50-3.59), obesity and DM (obesity alone: 1.36, 1.07-1.71; DM alone: 1.85, 1.39-2.47; obesity and DM: 1.89, 1.34-2.67; vs no obesity and no DM), higher disease activity and GC intake (remission/low disease activity and GC intake: 1.96, 1.36-2.82; moderate/severe disease activity and no GC intake: 1.35, 1.05-1.72; moderate/severe disease activity and GC intake 2.30, 1.41-3.74; vs remission/low disease activity and no GC intake). Conversely, the following variables were associated with less severe COVID-19 outcomes: time period after 15 June 2020 (16 June 2020-31 December 2020: 0.42, 0.34-0.51; 1 January 2021 onwards: 0.52, 0.41-0.67; vs time period until 15 June 2020), a diagnosis of PsO (without arthritis) (0.49, 0.37-0.65; vs PsA), and exposure to TNFi (0.58, 0.45-0.75; vs no DMARDs), IL17i (0.63, 0.45-0.88; vs no DMARDs), IL-23/IL-12 + 23i (0.68, 0.46-0.997; vs no DMARDs) and NSAIDs (0.77, 0.60-0.98; vs no NSAIDs).

Conclusion

More severe COVID-19 outcomes in PsO, PsA and axSpA are largely driven by demographic factors (age, sex), comorbidities, and active disease. None of the DMARDs typically used in PsO, PsA and axSpA, were associated with severe COVID-19 outcomes, including IL-17i, IL-23/IL-12 + 23i, JAKi and apremilast.

Development and Implementation of the AIDA International Registry for Patients With Still's Disease

Objective

Aim of this paper is to present the design, construction, and modalities of dissemination of the AutoInflammatory Disease Alliance (AIDA) International Registry for patients with systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still's disease (AOSD), which are the pediatric and adult forms of the same autoinflammatory disorder.

Methods

This Registry is a clinical, physician-driven, population- and electronic-based instrument implemented for the retrospective and prospective collection of real-world data. The collection of data is based on the Research Electronic Data Capture (REDCap) tool and is intended to obtain evidence drawn from routine patients' management. The collection of standardized data is thought to bring knowledge about real-life clinical research and potentially communicate with other existing and future Registries dedicated to Still's disease. Moreover, it has been conceived to be flexible enough to easily change according to future scientific acquisitions.

Results

Starting from June 30th to February 7th, 2022, 110 Centers from 23 Countries in 4 continents have been involved. Fifty-four of these have already obtained the approval from their local Ethics Committees. Currently, the platform counts 290 users (111 Principal Investigators, 175 Site Investigators, 2 Lead Investigators, and 2 data managers).

The CHRONOS Real-World Evidence of Biologic Treatments in Psoriatic Arthritis in Italy: A Post Hoc Gender Analysis

Background: Phenotypic features and outcome differences between sexes have been reported in psoriatic arthritis (PsA). However, little is known about sex differences in effectiveness of biologics in clinical practice. Methods: Post hoc gender analysis of the CHRONOS, a multicenter, noninterventional, retroprospective Italian real-world study assessing 6-month and 1-year effectiveness of biologics for PsA. Results: Eligible patients were 399, 43.1% men. Sociodemographic characteristics, type of arthritis, baseline Disease Activity Score 28 joints (DAS28), and duration of biologic treatment were rather homogeneous. More men were overweight/obese and naive to biologics. The most frequently used biologics were TNF-inhibitors and secukinumab in both sexes. DAS28 responders were 72.7% (women) and 70.5% (men) at 6 months, and 68.0% in both sexes at 1 year. American College of Rheumatology (ACR) response showed a trend for men versus women to achieve more frequently ACR50 (32.6% vs. 26.5% at 6 months; 34.9% vs. 20.0% at 1 year) and ACR70 (22.3% vs. 12.4% at 6 months and 25.0% vs. 13.0% at 1 year). Global satisfaction with treatment at enrollment and after 6 months was slightly higher among men [mean (standard deviation) Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9) score: 68.6 (18.6) and 69.9 (18.2), respectively] than women [65.3 (18.2), 66.2 (18.5)]. Conclusions: Overall response to biologics for PsA was rather favorable. With similar baseline disease severity, men appear to have a somewhat earlier and better response with higher treatment satisfaction.

Quality of life and therapeutic management of axial spondyloarthritis patients in Italy: a 12-month prospective observational study

OBJECTIVES

To evaluate the health-related quality of life (HRQoL), disease activity, treatment adherence, and work ability in the real-world setting in patients with axial spondyloarthritis (axSpA).

METHODS

QUASAR was a prospective 12-month, observational study involving 23 rheumatology centres across Italy, including adult patients with axSpA according to the Assessment of SpondyloArthritis International Society (ASAS) criteria. Patients were followed at baseline, 3, 6, and 12 months for disease activity and health-related QoL (HRQoL), treatment adherence and work ability. Regression analysis was used to assess the association between treatment and outcome variables.

RESULTS

413 (80.7%) out of axSpA 512 patients were diagnosed with ankylosing spondylitis (AS) and 99 (19.3%) with non-radiographic axSpA (nr-axSpA). Nr-axSpA and AS patients had similar baseline disease activity and HRQoL. Biologic disease-modifying anti-rheumatic drugs (bDMARDs) were the most frequent medication (n=426, 83.2%). Over the 1-year follow-up, disease activity measures (joint pain and swelling, CRP, global assessment, BASDAI, ASDAS), HRQoL and work ability significantly improved, while few differences emerged between nr-axSpA and AS patients. Treatment satisfaction and adherence questionnaires improved over the 12 months. Patients treated with bDMARDs showed improved outcomes for disease activity measures and HRQoL variables, greater benefit observed in patients with AS.

CONCLUSIONS

We found clinical and HRQoL improvement over 1 year in a large, real-world population of nr-axSpA and AS patients treated with bDMARDs or conventional synthetic DMARDs.

AB0241 PREVALENCE OF ANXIOUS SYMPTOMS AND DEPRESSION IN A SAMPLE OF PATIENTS WITH RHEUMATOID ARTHRITIS (RA) AND OTHER CHRONIC RHEUMATIC DISEASES

Background:

Clinical practice with patients suffering from chronic diseases highlights the presence of psychological symptoms of discomfort fed by biological and non-biological mechanisms linked to disease and treatment. In rheumatic diseases, literature detects the presence of anxious symptoms and depressed mood of clinical and sub-clinical importance with a multifactorial genesis1.

Objectives:

To detect the impact on the state of health of anxious symptoms and depressed mood in a population suffering from RA and other rheumatic diseases in order to implement the effectiveness of psychological intervention through the selection of patients who present critical levels of discomfort.

Methods:

Patients afferent to the Rheumatology outpatient clinic of Mauriziano Hospital have been screened from May 2018 to July 2018 with two self-administered questionnaires: HADS-A and HADS-D (Hospital Anxiety and Depression Scale), specifically developed for the evaluation of anxious and depressive symptoms in medical pathologies, and HAQ (Health Assessment Questionnaire) to explore functional disability. Data about rheumatic diagnosis and socio-demographic characteristics were also collected. Data were analyzed with descriptive statistics; the Student Test and the ANOVA test were used to evaluate prevalence and to compare the presentation of symptoms in the different diseases and the Pearson correlation coefficient was used to evaluate the relationship between symptoms and disability.

Results:

A total of 427 subjects were screened (317 females and 110 males), aged between 19 and 90 years (mean 60 ± 14 yrs). 156 subjects (36.5%) had a diagnosis of RA, 76 (17.8%) of psoriatic arthritis, 42 (9.8%) of ankylosing spondylitis, 14 (3.3%) of systemic lupus erythematosus and 139 (32.6%) of other rheumatic diseases (including Sjogren, osteoarthritis, fibromyalgia).

A high prevalence of anxious symptoms and depressed mood has been found and the number of subjects reporting scores indicating a clinically relevant uncomfortable situation (HADS ≥ 11) was also relevant (Table 1); an increased prevalence in female patients was observed. There were no differences in the presentation of symptoms between RA and the other included pathologies (Table 2).

There was a positive and significant correlation between anxious symptoms or depressed mood and functional disability (0.49 and 0.60 respectively, p<0,01).

Conclusion:

The results show a significant presence of uncomfortable situations that could evolve in a psychopathological sense. The discomfort expressed through anxious and depressive symptoms is related to the level of functional disability. Recognizing the presence of psychological distress allows to orient the treatment plan and facilitate the patient’s adaptation to the disease condition.

FRI0273 EFFECTIVENESS AND RETENTION RATE OF SECUKINUMAB FOR PSORIATIC ARTHRITIS AND AXIAL SPONDYLOARTHRITIS: REAL-LIFE DATA FROM THE ITALIAN LORHEN REGISTRY

Background:

Observational data on the use of secukinumab for the treatment of spondyloarthritides are still lacking. Large population-based registries that allow long-term follow-up have been increasingly used to investigate the performance of biologic drugs in a real life setting.

Objectives:

The aim of this study is to evaluate the effectiveness and the retention rate of secukinumab in psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA) patients in a real-life setting over a 3-year follow-up period.

Methods:

Data of all PsA and axSpA patients (diagnosed according to CASPAR and ASAS criteria, respectively) treated with secukinumab were prospectively collected in the Italian multicentric LORHEN registry. Effectiveness was measured as the mean change from baseline of Disease Activity in PSoriatic Arthritis score (DAPSA) in PsA and Ankylosing Spondylitis Disease Activity Score (ASDAS) in axSpA patients. Rates of DAPSA remission and ASDAS inactive disease were also computed. The 3-year retention rate was calculated by the Kaplan-Meier method and compared between PsA and axSpA by a log-rank test. A descriptive analysis of reasons for discontinuation was performed.

Results:

The study population included 195 PsA (55.4% females, mean age 50.7 [±11.8] years, mean disease duration 10 [±7.8] years, mean baseline DAPSA 23.12 [±12.3]) and 94 axSpA (61.7% males, mean age 49.1 [±12.7] years, mean disease duration 10.4 [±9.4] years, mean baseline ASDAS 3.41 [±1.1]) patients who received secukinumab as first (26.5 and 33%, respectively) or subsequent biologic agent. Compared with baseline, the 3-, 6- and 12-month mean values of both DAPSA (12.6 [±9], 11.2 [±10.5] and 9.3 [±7.5], respectively) and ASDAS (2.23 [±0.9], 2.15 [±0.9], and 1.84 [±0.9], respectively) were significantly decreased (p<0.001 for all the timepoints). The 3-, 6-, and 12-month rates of remission/inactive disease were 15.5, 25.4, and 30.5% in PsA and 18, 23.7, and 28.6% in axSpA group, respectively. One- and 3-year retention rate (figure 1) were respectively 79.4% and 66.6% in PsA and 72.3% and 70.1% in axSpA patients, with no significant difference between the two groups (p=0.517). The most frequent reason for withdrawal was inefficacy in both PsA (n=41) and axSpA (n=20), whereas only 8 PsA and 6 axSpA patients discontinued secukinumab because of adverse events.

Conclusion:

Our data confirmed in a real-life setting the 1-year clinical efficacy and the 3-year survival of secukinumab in both PsA and axSpA. The safety profile of secukinumab was very favorable for both the indications. No significant differences were observed in the performance of secukinumab between ax-SpA and PsA.

OP0063 QUANTITATIVE COMPUTED TOMOGRAPHY PREDICTS 10-YEAR MORTALITY IN INTERSTITIAL LUNG DISEASE RELATED TO SYSTEMIC SCLEROSIS

Background:

Interstitial lung disease (ILD) is the main cause of death in Systemic Sclerosis (SSc). Chest CT is the gold standard in detecting ILD although it is not easy to understand its prognostic value. ILD qualitative assessment is almost worthless. Goh et al. semi quantitative score of ILD extent is related to mortality risk but it is burdened by relevant inter/intra-readers variability. An operator independent algorithm based on voxel-wise analysis proved to identify SSc patients with an increased risk of mortality according to prediction models.

Objectives:

To verify if quantitative analysis of chest CT (QCT) predict 10 years-mortality in SSc patients.

Methods:

SSc patients with availability of a chest CT were enrolled in 13 different centers. The CT voxel-wise analysis with a free software (www.horosproject.com) provided QCT indexes: kurtosis, skewness, mean lung attenuation and standard deviation. Patients characteristics, autoimmune profile and pulmonary function test were collected. The follow-up interval lasted from the date of chest CT to the one of the last visit or death. Each QCT index cutoff, established in a previous study (1), clustered patients in two groups. Kaplan-Meier analysis estimated and compared survival in the above mentioned groups. p < 0.05 was considered statistically significant.

Results:

Five hundred sixty three SSc patients were enrolled (35938 patient-months); 52.4% had ILD detectable at CT scan. For each QCT index cutoff the cohort was split in two subgroups without differences in terms of sex, age, disease duration, autoimmune profile. All QCT indexes’ cutoff selected subgroups with statistically different survival rate (e.g in Figure 1).

Figure 1

Conclusion:

QCT can arise as the new gold standard in identifying SSc patients with poor prognosis. The real possibility to stratify SSc subjects according mortality risk will have a pivotal role in ILD treatment decisional process with the incoming anti-fibrotic drugs.

Alveolar haemorrhage in ANCA-associated vasculitis: Long-term outcome and mortality predictors

INTRODUCTION

Alveolar haemorrhage (AH) is considered an important cause of morbidity and early mortality in anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitides (AAV).

OBJECTIVES

The aim of this study was to identify predictors of outcome in patients with AH-AAV and to evaluate outcome and causes of death in this subset.

MATERIALS AND METHODS

A multicenter retrospective study was conducted in 29 Italian Centers. Clinicians were asked to recruit all patients diagnosed with AAV-associated AH during the last 10 years, from 2007 to 2016. Univariate and multivariable analysis were performed.

RESULTS

One-hundred and six patients were included (median age at onset of 55 years [IQR 42-67]). The majority were ANCA-positive (PR3 57.1%, MPO 33.7%) and 72.6% had also renal involvement. At presentation, anaemia was shown in 97 (92.4%) patients, hemoptysis in 54 (51.9%), respiratory failure in 68 (66.7%), of whom 48 (70.6%), requiring respiratory support. At the end of the 37 months [IQR 13-77] follow-up, 19/106 (17.9%) patients were dead. The main causes of death were active disease and infections. By stepwise regression analysis, age >65 years (HR 3.66 [95% CI 1.4-9.51], p = 0.008) and the need for respiratory support (HR 4.58 [95% CI 1.51-13.87], p = 0.007) at AH onset were confirmed to be predictive of mortality.

CONCLUSIONS

Predictors of outcome in AAV-AH were determined. Factors related to the patient's performance status and the severity of the lung involvement strongly influenced the outcome. Balancing harms and benefits for the individual patient in induction and maintenance treatment strategies is crucial.

Effectiveness of Adalimumab for the Treatment of Psoriatic Arthritis: An Italian Real-Life Retrospective Study

Background: Few studies have evaluated the effectiveness of adalimumab in the real-life setting in psoriatic arthritis (PsA).

Objective: To evaluate the 2-year retention rate of adalimumab in PsA patients. Potential baseline parameters influencing persistence on treatment were also evaluated.

Methods: PsA patients from 16 Italian Rheumatology Units treated with adalimumab as first- or second-line biological therapy were retrospectively evaluated. Adalimumab retention rate was evaluated at 12 and 24 months. Logistic regression was used to evaluate the association between predictor variables and adalimumab retention rate.

Results: From 424 patients (53.5% male, aged 48.3 ± 12.8 years) who started treatment with adalimumab, 367 (86.6%) maintained treatment for 12 months and 313 (73.8%) for 2 years. At 24-months, Disease Activity in PsA (DAPSA) remission (defined as ≤4) and Low Disease Activity (LDA) (≤14) were achieved in 22.8% and 44.4% of patients, respectively. Adalimumab treatment significantly decreased the number of tender (7.0 ± 5.7 at baseline vs. 2.3 ± 3.5 at 24 months, p < 0.001) and swollen joints (2.7 ± 2.8 at baseline vs. 0.4 ± 0.9 at 24 months, p < 0.001), DAPSA (25.5 ± 10.9 at baseline vs. 11.0 ± 8.4 at 24 months, p < 0.001), PASI (5.3 ± 5.7 at baseline vs. 2.7 ± 2.8 at 24 months, p < 0.001) and CRP (3.8 ± 6.3 at baseline vs. 1.2 ± 1.7 at 24 months, p < 0.001). Among a range of laboratory and clinical variables, only female gender was associated with improved adalimumab persistence at 24 months (OR: 1.98, 95% CI: 1.2–3.2, p = 0.005).

Conclusions: Independent of a range of predictor variables, adalimumab was shown to be effective, while maintaining a high retention rate after 2 years in PsA patients.

Vitamin D and immunomodulation in early rheumatoid arthritis: A randomized double-blind placebo-controlled study

The aim of this study was to evaluate differences in T helper cell sub-types and osteoclast (OCs) precursors in peripheral blood between patients affected by early rheumatoid arthritis (eRA) and healthy controls. The effect of administration of cholecalcipherol on clinical and laboratory parameters was subsequently evaluated, by a parallel, randomized double blind, placebo controlled trial. Thirty nine eRA patients and 31 age-matched controls were enrolled and compared for levels of 25OH vitamin D, T helper cell sub-types, OCs precursors including both classical and non-classical and pro-inflammatory cytokines at baseline. Eligible patients were female ≥18 years of age with a diagnosis of RA, as defined by the American College of Rheumatology 2010 criteria for <6 months prior to inclusion in the study. Patients with auto-immune or inflammatory diseases other than RA were excluded. Patients treated with glucocorticoids (GCs), disease modifying activity drugs and biologic agents within the past 6 months were also excluded. In the second phase of the study, eRA patients were randomly assigned to standard treatment with methotrexate (MTX) and GCs with (21) or without (18) cholecalcipherol (300,000 IU) and followed for 3 months; the randomization was done by computer generated tables to allocate treatments. Three patients didn’t come back to the follow up visit for personal reasons. None of the patients experienced adverse events. The main outcome measures were T cells phenotypes, OCs precursors and inflammatory cytokines. Secondary outcome measure were clinical parameters. In eRA, 25OH vitamin D levels were significantly lower. CD4+/IFNγ+,CD4+/IL4+, CD4+/IL17A+ and CD4+IL17A+IFNγ+, cells were increased in eRA as well as non-classical OCs precursors, whereas T regulatory cells were not altered. TNFα, TGFβ1, RANKL, IL-23 and IL-6 were increased in eRA. Non-classical OCs, IL-23 and IL-6 correlated with disease severity and activity. Standard treatment with MTX and GC ameliorated clinical symptoms and reduced IL-23, whereas it did not affect CD4+ cells sub-sets nor OCs precursors. After 3 months, the combined use of cholecalcipherol significantly ameliorated the effect of treatment on global health. In eRA, a significant imbalance in T CD4+ sub-types accompanied by increased levels of non-classical OCs precursors and pro-inflammatory cytokines was observed. A single dose of cholecalcipherol (300,000 IU) combined with standard treatment significantly ameliorates patients general health.

Systemic onset juvenile idiopathic arthritis: a retrospective study of 80 consecutive patients followed for 10 years

OBJECTIVE

To investigate the relationships between systemic onset juvenile idiopathic arthritis disease activity, course of the disease, and functional class according to Steinbrocker.

METHODS

The records of all children with systemic onset juvenile arthritis (JA) according to the American College of Rheumatology criteria attending our center since 1971 with a minimum followup period of 3 years were reviewed. A cohort of 80 consecutive patients entered the study: 42 males, 38 females, mean age at onset 6.3 years (range 0.7-16), mean followup period 10.7 years (range 3-33). The cumulative duration of the active periods (CDAP) in months was calculated for every patient.

RESULTS

Three patterns of disease course were apparent: monocyclic (subtype I), intermittent (subtype II), and persistent (subtype III). At the last control the functional class and disease activity status were evaluated. In all subtype I patients (9 cases) the disease was in remission and no patient was in class II, III, or IV. In subtype II patients (27 cases), 16 were inactive or in remission and 6 in class III. In subtype III (44 cases) 21 were inactive or in remission and 17 were in class III or IV. The equation relating the Steinbrocker class to the CDAP was calculated considering the functional outcome as the dependent variable. The linear regression equation y = 0.0083 x + 1.266 was found with a correlation coefficient r = 0.586 (p < 0.0001). The majority of our patients were treated with disease modifying antirheumatic drugs, which in many cases were effective in reducing the duration of the active phases of disease.

CONCLUSION

Systemic onset JA may present with different clinical courses; the functional outcome is always good in subtype I (monocyclic), but can be poor in subtypes II and III. The severity of disability evaluated according to Steinbrocker classes is dependent on the cumulative duration of the active periods of the disease.

Validation of the Italian version of the Stanford Childhood Health Assessment Questionnaire for measuring functional status in children with chronic arthritis

The Stanford Health Assessment Questionnaire developed by Singh et al. to measure functional status in children with chronic arthritis (CHAQ) was translated into Italian (I-CHAQ), with minor modifications to obtain cross-cultural equivalence. This version was evaluated in a series of 96 patients with juvenile rheumatoid arthritis (JRA), both males and females ranging in age from 3 to 19 years (mean age 9.9 years). All three onset subtypes and all four classes of disability were represented in the sample. The questionnaire was filled in by the parents if the children were less than 8 years of age (23 cases), and by the children themselves in all other cases; a health professional was always present to provide assistance. As expected, JRA patients with a systemic or polyarticular disease onset had higher scores than those with a pauciarticular onset, and there were statistically significant differences in disability index values between patients from different Steinbrocker functional classes. The instrument showed good reproducibility in a test-retest over a two-week period, a high correlation between the child and parent scores, excellent internal reliability, and good convergent and discriminant validity.

Lung function and diffusing capacity for carbon monoxide in patients with juvenile chronic arthritis: effect of disease activity and low dose methotrexate therapy

OBJECTIVE

We measured lung function, in terms of lung volumes, forced expiratory flow-volume curves and diffusing capacity of carbon monoxide (DLCO), in a group of 61 patients with juvenile chronic arthritis (42 female; age range 5 to 33 years) to ascertain whether disease activity and treatment with low dose methotrexate (MTX) influenced these parameters. The whole population was divided into subgroups based on onset type (systemic, n = 27; pauciarticular, n = 12; polyarticular, n = 22), disease activity (active, n = 42; inactive, n = 19), and MTX treatment (treated, n = 27; not treated, n = 34).

RESULTS

We found that maximal-mid expiratory flow (MMEF) was significantly reduced in patients with active disease (p < 0.025). The mean DLCO value, expressed as a percentage of the predicted value, and DLCO corrected for the hemoglobin value were lower than expected (67% and 80%, respectively). Multiple regression analysis showed that the forced vital capacity (FVC), forced expiratory flow in one second (FEV1) and DLCO were all correlated to the clinical subtype of the disease (p < 0.05, p < 0.02, p < 0.02, respectively), and MMEF was related to disease activity (p < 0.025). There was no evidence of any effect of MTX treatment on the pulmonary parameters.

CONCLUSION

This study confirms that JCA is characterized by an impairment of lung function, mainly involving the small airways, and by interstitial damage. These changes are related to the clinical subtypes of the disease and to disease activity.

The anticytokine neuropeptide alpha-melanocyte-stimulating hormone in synovial fluid of patients with rheumatic diseases: comparisons with other anticytokine molecules

The aim of this study was to determine if the anticytokine neuropeptide alpha-melanocyte-stimulating hormone (alpha-MSH) occurs, along with interleukin 1 receptor antagonist (IL-1ra) and soluble tumor necrosis factor receptor (sTNFr), in synovial fluid of patients with rheumatoid arthritis (RA), juvenile chronic arthritis (JCA), or osteoarthritis. The data show that alpha-MSH does occur in the synovial fluid and its concentrations are greater in patients with RA than in those with osteoarthritis. Synovial fluid concentrations of IL-1ra and sTNFr were likewise greater in RA. Further, concentrations of alpha-MSH, IL-1-ra, and sTNFr were greater in patients with polyarticular/systemic-onset JCA than in those with pauciarticular disease, that is in patients with greater joint inflammation. Concentrations of alpha-MSH were greater in synovial fluid than in plasma in a substantial proportion of patients, suggesting local production of the peptide; this is the first indication that the anticytokine molecule alpha-MSH is produced within a site of inflammation. Further, it appears that local production of alpha-MSH is induced particularly in those arthritic joints that have more intense inflammatory reactions. This finding, combined with previous evidence of the marked anti-inflammatory activity of alpha-MSH, suggests that the peptide acts locally to modulate proinflammatory influences in rheumatic diseases.

Clonal expansions of V delta 1+ and V delta 2+ cells increase with age and limit the repertoire of human gamma delta T cells

We have investigated the complexity of the human gamma delta T cell repertoire by means of a VJ heteroduplex analysis method. cDNA obtained from peripheral blood mononuclear cells was amplified with V delta 1-C delta or V delta 2-C delta primers. The product was denatured and renatured to allow random reannealing of the strands and the heteroduplexes carrying mismatched junctional sequences were separated from the homoduplexes on polyacrylamide gels. Whenever one or more T cell clones were expanded to over 10% of the polyclonal background, discrete bands of homo- and heteroduplex appeared. This method was applied to the analysis of the peripheral gamma delta compartment from healthy donors and rheumatoid arthritis patients of different ages. While samples from young individuals showed a polyclonal pattern, a clear tendency towards oligoclonality appeared with increasing age, both in normal individuals and rheumatoid arthritis patients. We also show that the VJ junctional sequence derived from the heteroduplex fragments can be successfully used to isolate and characterize the corresponding T cell clones in vitro, even after a period of 1 year. In conclusion, our findings indicate that the complexity of the gamma delta T cell repertoire decreases with age as a consequence of the expansion of a few T cell clones.
