Abstract: Synovial diseases of the hip are often overlooked because they are far less frequent that osteoarthritis and because this joint is deep and so difficult to examine. The more important cause is septic arthritis; it requires an hospitalization in emergency. Synovial tissue may also be at the beginning of the spondylarthropathy or, more rarely, of rheumatoid arthritis. In acute forms, diagnosis must be done before any radiological destructive changes. Aspiration of the hip and synovial biopsy are necessary for the diagnosis. In subacute or chronic forms, computed tomography and/or magnetic resonance imaging are useful tools to suspect the diagnosis and to guide a biopsy.

Abstract: OBJECTIVES: Prescribing foot orthotics in rheumatoid arthritis patients with symptomatic forefoot involvement is a standard practice. However, limited research has been reported regarding gait and pain improvement with the use of foot orthotics. PATIENTS AND METHODS: Sixteen patients (13 F, 3 M; mean age: 52 +/- 12 years) with metatarsalgia due to rheumatoid arthritis were included in this prospective, randomized with crossover study, and received foot orthotics. At 1 month follow-up, space and time gait variables with and without foot orthotics were assessed by Bessou's locometer; pain was assessed by visual analogue scale (VAS). RESULTS: Pain levels significantly decreased (P = 0.008) by wearing foot orthotics. Despite a significant step length increase (P = 0.05) with orthotics, there was no significant improvement of stride length, cadence, or walking speed which was the main assessment criterion. CONCLUSIONS: Wearing foot orthotics improves pain, but not sufficiently to improve gait in rheumatoid arthritis patients with metatarsalgia. Foot orthotics improved comfort levels because of a decrease in pain, but was not sufficient to correct gait.

Abstract: OBJECTIVE: Tuberculosis (TB) is associated with anti-tumor necrosis factor (anti-TNF) monoclonal antibody (mAb) therapy, but whether this association is drug-specific remains a concern. Our objective was to describe cases of TB associated with anti-TNF mAb therapy, identify risk factors, and estimate the incidence. METHODS: We conducted an incidence study and a case-control analysis to investigate the risk of newly diagnosed TB associated with the use of anti-TNF agents. As part of the French Research Axed on Tolerance of Biotherapies (RATIO) registry, for 3 years we collected cases of TB among French patients receiving anti-TNF mAb therapy for any indication; for each case, 2 patients treated with anti-TNF agents served as control subjects. RESULTS: We collected 69 cases of TB in patients treated for rheumatoid arthritis (n = 40), spondylarthritides (n = 18), inflammatory colitis (n = 9), psoriasis (n = 1) and Behçet's disease (n = 1) with infliximab (n = 36), adalimumab (n = 28), and etanercept (n = 5). None of the patients had received correct chemoprophylactic treatment. The sex- and age-adjusted incidence rate of TB was 116.7 per 100,000 patient-years. The standardized incidence ratio (SIR) was 12.2 (95% confidence interval [95% CI] 9.7-15.5) and was higher for therapy with infliximab and adalimumab than for therapy with etanercept (SIR 18.6 [95% CI 13.4-25.8] and SIR 29.3 [95% CI 20.3-42.4] versus SIR 1.8 [95% CI 0.7-4.3], respectively). In the case-control analysis, exposure to infliximab or adalimumab versus etanercept was an independent risk factor for TB (odds ratio [OR] 13.3 [95% CI 2.6-69.0] and OR 17.1 [95% CI 3.6-80.6], respectively). Other risk factors were age, the first year of anti-TNF mAb treatment, and being born in an endemic area. CONCLUSION: The risk of TB is higher for patients receiving anti-TNF mAb therapy than for those receiving soluble TNF receptor therapy. The increased risk with early anti-TNF treatment and the absence of correct chemoprophylactic treatment favor the reactivation of latent TB.

Abstract: OBJECTIVE: To suggest recommendations for management of acute infusion reactions induced by infliximab in patients with rheumatoid arthritis (RA) and spondyloarthritis (SpA). METHODS: In total, 203 patients were treated with infliximab (120 ml/h). Prevalence of acute infusion reaction was evaluated. To manage these conditions, recommendations were devised according to the type and the severity of clinical manifestations, which were classified beforehand in 2 groups: A (hypertension, pruritus, sudden flush, vomiting, tachycardia or bradycardia, shivers, fever) and B (urticaria, tickling throat, Quincke's edema, dyspnea, and hypotension). Recommendations were based mainly on adjustment of the infusion rate. RESULTS: It was observed that 23/203 patients (11.3%) had acute infusion reactions. Among them and prior to our recommendations, infliximab was completely discontinued in 8/23 patients. After our recommendations were implemented, 15/23 patients presented an acute infusion reaction: 8 and 7 patients with symptoms of Group A and B, respectively. In Group A (8 patients), reducing the infusion rate to 60-80 ml/h led to disappearance of symptoms; the modified treatment was then maintained. In Group B (7 patients), the infusion was immediately stopped and appropriate drugs were administered. Once clinical manifestations were alleviated, the infusion was resumed (60 ml/h). Prior to subsequent infusions (60 ml/h), a premedication was administered. CONCLUSION: Based on these recommendations, infliximab could be maintained with great efficacy on disease activity in every patient with an acute infusion reaction. Our recommendations permit sustained administration of infliximab and allow every patient to benefit from this therapy.

Abstract: Tumour necrosis factor (TNF)-alpha plays a key role in the pathogenesis of rheumatoid arthritis (RA). It binds to two receptors, namely TNF receptor (TNFR)I and TNFRII. Several studies have suggested an association between TNFRII 196R/R genotype and RA. The objective of the present study was to evaluate the predictive value of the TNFRII 196R allele for RA diagnosis and prognosis in a cohort of patients with very early arthritis. We followed up a total of 278 patients recruited from the community, who had swelling of at least two joints that had persisted for longer than 4 weeks but had been evolving for less than 6 months, and who had not received disease-modifying antirheumatic drugs or steroid therapy. At 2 years, patients were classified according to the American College of Rheumatology criteria. All patients were genotyped with respect to TNFRII 196M/R polymorphism. Radiographs of hands and feet (read according to the modified Sharp method) and the Health Assessment Questionnaire were used to quantify structural and functional severity. The cohort of 278 patients was found to include 156 and 122 RA and non-RA patients, respectively. The TNFRII 196R allele was found to be associated with RA (P = 0.002). However, progression of radiographic severity and Health Assessment Questionnaire scores over 1 year did not differ between carriers of the 196R allele and noncarriers. Our findings suggest that the TNFRII 196R allele may be associated with RA diagnosis but that it does not predict early radiographic progression or functional severity in patients with very early, unclassified arthritis.

Abstract: The objective of this study was to determine the diagnostic and prognostic values of antiglucose-6-phosphate isomerase (GPI) antibodies in patients with very early arthritis. Anti-GPI antibodies were measured by ELISA using purified GPI from rabbit muscle in: (i) 383 sera from healthy blood donors (n = 120), well-established rheumatoid arthritis (RA) (n = 99) and non-RA differentiated arthritis (NRADA) (n = 164) patients; (ii) 195 sera obtained from community-recruited patients with very early inflammatory arthritis (VErA cohort) that were studied for 1 year and classified as having RA (n = 116), NRADA (n = 41), and undifferentiated arthritis (UA) (n = 38) after the follow-up period. The criterion for severity was the progression of radiographic damage. Prevalence of anti-GPI antibodies was significantly higher in well-established RA patients (45.4%) compared to healthy subjects (2.5%). Anti-GPI antibodies were also present in sera from NRADA: systemic lupus erythematosus 53%, polymyositis 45.4%, adult-onset Still's disease 44%, systemic sclerosis 42.8%, spondylarthropathies 25% and primary Sjögren's syndrome 5.8%. No significant association was found between the presence of anti-GPI antibodies and the 3 diagnostic groups from the VErA cohort. No correlation was observed between anti-GPI and autoantibodies usually associated with RA. Anti-GPI antibodies were not predictive of radiological progression in patients with very early arthritis. Thus, anti-GPI antibodies are not useful for discriminating RA from non-RA rheumatic diseases and do not constitute a predictive factor of structural damage.

Abstract: OBJECTIVE: To evaluate the predictive value of clinical, biological and radiological parameters for the prognosis of rheumatoid arthritis (RA) in a community-recruited cohort. METHODS: Ninety-one patients (mean age 49 yr, female/male ratio 2.9) with RA of limited duration (median 2 yr), 80% recruited from the community, were prospectively enrolled in 1996 (T1) and followed until 1999 (T2). Data collected at T1 were demographic characteristics, Ritchie articular index (RAI), extra-articular manifestations, Health Assessment Questionnaire (HAQ) score, C-reactive protein (CRP) and autoantibodies (autoAbs) [rheumatoid factors (RF), detected by latex fixation test and ELISA (IgM, IgA and IgG isotypes), anti-filaggrin, detected by immunofluorescence (anti-keratin antibodies, AKA; anti-perinuclear factor antibodies, APF) and ELISA (anti-citrullinated rat filaggrin antibodies, ACRFA), anti-Sa, anti-calpastatin recognizing the 27 C-terminal fragment (ACAST-C27) and domain I (ACAST-DI), anti-cardiolipin (ACL), antineutrophil cytoplasmic antibodies (ANCA), anti-annexin V (aANX V) and anti-Ro]. Hands were radiographed at T1 and T2, and read using the Sharp method as modified by van der Heijde. The main assessment criterion was progression of radiologically detected damage between T1 and T2. RESULTS: At T1, RA activity was mild (RAI 11/78; mean CRP 14 mg/ml), with minor functional disability (HAQ 0.8/3) and mild X-ray destruction (mean total Sharp score 9.2/280). At T1, 96% of the patients were on treatment (prednisone 72%, DMARDs 95%). The latex test detected autoAb in 46% of patients, RF-IgM was detected in 51%, RF-IgA in 36%, RF-IgG in 32%, AKA in 33%, APF in 45%, ACRFA in 45%, ACAST-C27 in 14%, ACAST-DI in 5%, anti-Sa in 22%, ACL in 3%, ANCA in 28%, aANX V in 9% and anti-Ro in 2%. At T2, the mean total Sharp score was 22.9. According to univariate analysis, T1 parameters associated with the independent variable were RAI, HAQ, CRP, latex test positivity and T1 Sharp scores. Multivariate analysis retained only latex test positivity and, to a lesser degree, joint-space narrowing score as independent predictors of radiological progression. CONCLUSION: RF is the main factor that can predict radiological progression in community cases of RA of limited duration.
