An incomplete form of childhood Behçet's disease treated with infliximab.

Behçet's disease (BD) is a multi-systemic vasculitis characterized by the possible presence of cutaneous, ocular, articular and neurological manifestations. In this report, we examine the case of a fifteen-year-old boy with an incomplete form of juvenile Behcet's disease which began with joint involvement and developed into a complete form only after several years. The patient showed a rapid response to anti-TNF-alpha (infliximab) with an improvement of mucocutaneous lesions (oral and genital ulcers, pseudofolliculitis) and arthritis

OP0223 DEVELOPMENT AND PRELIMINARY VALIDATION OF ULTRASONOGRAPHIC DISEASE ACTIVITY AND DAMAGE SCORES IN PSORIATIC ARTHRITIS PATIENTS: RESULTS FROM THE UPSTREAM (ULTRASOUND IN PSORIATIC ARTHRITIS TREATMENT) STUDY

Background:The UPSTREAM (NCT03330769) is a 24-month multi-center prospective cohort study that primarily aims to evaluate the additional value of musculoskeletal ultrasound (msk-US) over clinical examination in predicting 6-month minimal disease activity in Psoriatic Arthritis (PsA). (1)Objectives:To develop and preliminarily validate an activity msk-US score and a damage msk-US score for PsA using the UPSTREAM database.Methods:Patients classified with PsA according to CASPAR criteria and starting a new course of therapy for clinically active peripheral joint disease were eligible. The information regarding objectives, study design, clinical and US assessment has already been published (1). The msk-US examination was performed in 42 joints, 36 tendons, 12 entheses and 2 bursae defined through a web-based exercise (2). The sonographic elementary lesions were allocated to disease activity [i.e. synovitis (sy), tenosynovitis (ts), peritendinitis (pt), bursitis (bs) all evaluated both in Grey Scale (GS) and Power Doppler (PD) and active enthesitis (en)] and to damage (i.e. joint erosion, bone proliferation, tendon tear, enthesophyte, calcification and irregular enthesis bone profile). Hands and feet X-ray were assessed using the modified Sharp-Van der Heijde (mSVH) score. A principal component (PC) analysis (PCA) was performed for each score and the number of PCs was defined by means of parallel analysis using baseline data. Each PC was normalized (n) taking into account the proportion between the observed value (e.g. sy-GS count) and the maximum expected value (e.g. 42 for sy-GS). Spearman' correlation was used to investigate the construct and discrimination validity of the new scores.Results:Between February 2017 and May 2020, 312 PsA patients (155 men), with a mean (SD) age of 52.8 13.4, were enrolled from 19 centers; 22 expert sonographers were involved with substantial agreement for US lesions evaluated (k ≥0.7). The median [IQR] disease duration was 1.3 [0.1-6.1] years and the median [IQR] tender joint and swollen joint counts were 6 [3-13] and 2 [1-5], respectively. The weight derived from PCA for each sonographic lesions and the final equation for calculating the scores are reported in Figure 1 (1A activity and 1B damage). The final msk-US activity score [n(ts-GS + ts-PD)*2.87] + [n(bs-GS + bs-PD)*1.76] + [n(pt-GS + pt-PD)*1.43] + [n(active en)*1.00] + [n(sy-GS)*0.83] + [n(sy-PD)*0.45] has the best construct and discrimination validities according to a significant correlation with all clinical variables usually related to clinical activity (Table 1). The msk-US damage score correlated with mSVH score, HAQ and other clinical variables (Table 1).Table 1.VariablesMsk-US activity scoreMsk-US damage scoreSpearman correlationP-valueSpearman correlationP-valueESR0.1960.0020.0750.235CRP0.209<0.0010.0680.254TJC0.338<0.0010.286<0.001SJC0.338<0.0010.0720.221Dactylitis count0.284<0.001-0.0610.306LEI0.1940.0010.214<0.001Physician GA0.150.0120.0160.793Patient GA activity0.1380.018-0.0730.221Patient GA pain0.1990.001-0.0270.648HAQ0.238<0.0010.1460.014BASDAI0.237<0.0010.1750.003PSAID-90.70.0040.1480.013DAPSA0.392<0.0010.228<0.001Sharp van Der Heijde score0.1150.20.2660.003Figure 1.Conclusion:These newly developed and preliminary validated msk-US activity and damage scores could be used in patients with PsA in the context of observational and controlled trials.References:[1]Canzoni M et al.

Relationship between the prevalence of subclinical tenosynovitis and treatment in patients with RA in clinical remission: STARTER study

Objective: This study is a sub-analysis from the patient cohort of the STARTER (Sonographic Tenosynovitis Assessment in RheumaToid arthritis patiEnts in Remission) study. The aim was to evaluate differences in ultrasound-detected joint and/or tendon involvement between patients receiving therapies based on a combination of conventional synthetic DMARDs (csDMARDs) and biologic DMARDs (bDMARDs) and those who were treated with either csDMARDs or bDMARDs in monotherapy. Material and methods: Four hundred and twenty-seven consecutive patients with a diagnosis of RA were recruited between October 2013 and June 2014. They were divided into three subgroups based on their therapy at baseline: patients with bDMARD in monotherapy, patients with csDMARD in monotherapy and patients in combination therapy (csDMARD + bDMARD). At baseline, 6 months and 12 months, a clinical examination (28 joint count) and an ultrasound evaluation were performed in each patient. A score of grey-scale (GS) and power Doppler (PD) synovitis and tenosynovitis was calculated based on the OMERACT scoring systems. Results: Two hundred and fifty-six patients completed the observation period: 48 patients from the bDMARD group (18.75%), 152 patients from the csDMARD group (59.38%) and 56 patients from csDMARD + bDMARD group (21.88%). The analysis showed that GS tenosynovitis and PD tenosynovitis are better controlled in combination therapy than they are ith csDMARD alone (P=0.025 and P=0.047, respectively); for PD synovitis, there was a better response in those who were treated with the combination therapy when compared with the patients receiving csDMARD (P=0.01) or bDMARD (P=0.02) alone. Conclusions: The analysis showed a lower prevalence of subclinical inflammatory manifestations detected with ultrasound imaging in those patients treated with the combination therapy than in those in monotherapy

Lack of hepatitis B virus reactivation after anti-tumor necrosis factor α agents therapy in antibody to hepatitis B core antigen positive/hepatitis B surface antigen negative subjects with chronic inflammatory arthropathies

Background: Hepatitis B virus (HBV) reactivation in patients positive for antibody to HB core antigen (anti-HBc), negative for HB surface antigen (HBsAg) and HBV-DNA (potential occult HBV carriers), treated with anti-tumor necrosis factor (TNF)α, is a debated question. The aim of the study was to evaluate the safety of anti-TNFα therapy in anti-HBc positive/HBsAg negative subjects with rheumatoid arthritis (RA) and spondyloarthropathy (SpA). Methods: All consecutive HBsAg negative RA and SpA outpatients referring to the Immuno-Rheumatology Institute at the S. Andrea hospital, Sapienza, University of Rome who had to undergo anti-TNFα therapy. Results: Among the 169 enrolled subjects, 20 (12%) were potential occult HBV carriers (anti-HBc positive, HBsAg and HBV-DNA negative patients with or without anti-HBs). During the follow-up (mean ± SD 45 ± 22 months), aminotransferases and HBV-DNA, tested every two and six months respectively, did not change. Conclusion: This study confirms the substantial safety of anti-TNFα therapy in potential occult HBV carriers RA and SpA patients. © 2014 European Federation of Internal Medicine

HLA alleles and susceptibility to osteoporosis in men

Background: Osteoporosis (OP) is a disease of the skeleton characterized by compromised bone strength leading to an increased risk of fracture. The disease predominantly affects women because of the important pathogenic role played by gonadal steroid, however in recent decades has been demonstrated the increased prevalence of OP in men. Osteoporosis is a multifactorial disease strongly influenced by genetics factors. Studiesof twins and families with OP show that the genetic contribution to the pathogenesis of OP is responsible for 50-80% of the interindividual variability in bone mineral density (BMD). Among the susceptibility genes involved a role could be played by the HLA polymorphism. Some studies of women report an increase in HLA-B7allele in osteoporotic patients compared with controls; in particular the increaseof HLA-B7 is linked to HLA A24-B7-DR1 and HLA B7-DR15-DQ6 haplotypes. Objectives: Typing for HLA I and II genes in49 men and 81 women with OP and in 107 healthy control individuals and assess any differences in allele distribution among the three groups, in order to identify possible susceptibility genes in osteoporotic men. Methods: We selected 49 men with osteoporosis, 18 belonging to primary osteoporosis and 31 to secondary osteoporosis due to inflammatory rheumatic diseases; a group of 107 healthy control and a group of 81 women (41 with prymary OP and 40 with secondary OP) were also studied. To analyze the statistical dependence of variables in different groups we used the χ2 test with one degree of freedom, or Fisher’s exact test when necessary. Results: We observed no differences among the three groups in the frequencies of alleles of loci HLA-DRB and HLADQB. Nevertheless, valuating HLA Class I loci we observed a significant increasein the frequency of HLA-B16 in the group of males compared to controls (16% vs 6%) Pc 0,03) and in respect to the women group.(16% vs 8% Pc 0,02). Conclusions: The study of the distribution of HLA alleles in males shows an increased frequency of HLA-B16, never described in other studies. However hasn’t been demonstrated the increased frequency of HLA-B7 previously found in women with OP. The association of HLA-B7 with the OP in women, confirmed by several studies, allows us to hypothesize that this allele may be a marker of susceptibility to OP. HLA-B16 could play the same role in the male population of OP; however, being an original data, obtained on a relatively small sample, it needs to be confirmed on larger series and further studies
