Abstract: Rheumatoid arthritis (RA) induces major changes in synovial tissue (ST) and cartilage and bone destruction. Still, its pathogenesis is poorly understood. Accumulating evidence points to an important role for B lymphocytes. Rheumatoid-ST is characterized by activation of the synoviocytes and infiltrated by various inflammatory cells such as B and T lymphocytes. The infiltrate is diffuse or organized as germinal centers (GCs). These accommodate the immune response and favor self-tolerance breakdown. Receptor revision in B cells results from re-expression of the recombination activating genes (RAGs) which reinitiate immunoglobulin gene recombination, and modify the B-cell antigen receptor accordingly. In rheumatoid ST, secondary VDJ rearrangements occur and RAG proteins are detected. The mechanism that triggers and controls this revision remains elusive. We favor the hypothesis that such an uncontrolled process leads to autoimmunity.

Abstract: The extent to which radiographs of the hands and feet can contribute to the diagnosis of early rheumatoid arthritis (RA) has received little research attention. Yet, the workup for recent-onset inflammatory joint disease usually includes radiographs of the hands and feet. We reviewed the literature for data on the value of these radiographs for diagnosing early RA. We sought to determine whether radiographic changes in the hands and feet constitute a valid diagnostic criterion, i.e., show good discrimination, good reproducibility, and an ability to detect early disease. Furthermore, we evaluated whether the sensitivity, specificity, and positive and negative predictive values of these changes could be calculated from published data. Few cohort studies of early inflammatory joint disease have been published, and the data come mainly from studies in early RA. Among radiographic alterations described to date, erosions seem associated with the best reliability and discriminating power. Radiographic alterations are of limited sensitivity for early rheumatoid arthritis because they occur only after some time. Radiographs of the hands and feet are far easier to obtain than magnetic resonance imaging and ultrasonography, which seem promising but are still undergoing validation.

Abstract: OBJECTIVE: There is evidence to support a dominant role for B cells in the pathophysiology of primary Sjögren's syndrome (SS). Therefore, we evaluated the safety and efficacy of anti-CD20 monoclonal antibody. METHODS: Sixteen patients who met the new American-European Consensus Group criteria for primary SS and scored >50 on at least 2 of 4 visual analog scales (VAS; 100 mm) evaluating global disease, pain, fatigue, and global dryness received infusions of low-dose rituximab (375 mg/m(2)) at weeks 0 and 1 without steroid premedication. RESULTS: Slow rituximab infusions (100 mg/hour) were well tolerated, with only 1 patient experiencing serum sickness-like disease. There was a dramatic reduction in B cells of the blood and salivary gland (SG). At week 12, VAS scores with respect to fatigue and dryness (P < 0.05), tender point count (P < 0.035), and quality of life as evaluated by the Short Form 36 questionnaire (SF-36; P < 0.001) were significantly improved. At week 36, significant improvements were noted in the 4 VAS scores (P < 0.05), tender joint count (P = 0.017), tender point count (P = 0.027), and SF-36 (P < 0.03). Pulmonary manifestations were ameliorated in 1 patient. Patients with improvements on at least 3 of the 4 VAS scores at any visit (n = 11) had a shorter disease duration than the other patients (n = 5; mean +/- SD duration 3.8 +/- 5.4 versus 30.1 +/- 29.5 years; P = 0.02). CONCLUSION: Low-dose rituximab infusions were well tolerated without the benefit of steroids. Infusions induced a rapid depletion of B cells in the blood and SG and could improve primary SS. Controlled studies are needed.

Abstract: OBJECTIVE: To evaluate the seroprevalence of hepatitis B (HBV) and C (HCV) in patients living in France with recent-onset polyarthritis suggesting rheumatoid arthritis. METHODS: The 813 patients in the ESPOIR cohort were screened for anti-HCV antibodies and HBs antigen. RESULTS: Seroprevalence was 0.86% for HCV (n = 7) and 0.12% for HBV (n = 1). HCV-related arthritis was diagnosed in 4 (0.5%) patients; no patient had HBV-related arthritis. HCV-seropositive patients had significantly higher transaminase levels (ALAT, 41.5 IU vs 23.2 IU, p = 0.02; and ASAT, 39.2 IU vs 21.8 IU, p = 0.001) but only 2 patients had ASAT or ALAT levels > 40 IU. No significant differences were found for anti-CCP antibodies, C-reactive protein, erythrocyte sedimentation rate, or other test. HCV seroprevalence was significantly higher in the subgroup with history of blood transfusion than in other patients (3.7% vs 0.42%, p = 0.02). Two of the 7 HCV positive patients and the single patient with confirmed hepatitis B infection were born in areas with higher prevalence of viral hepatitis (Togo, Senegal, Vietnam). Positive hepatitis status was known before study inclusion in 4 of the 7 HCV-positive patients and in the HBV-positive patient. CONCLUSION: The prevalence of HBV and HCV in a population of patients with recent-onset polyarthritis suggestive of RA was not greater than expected based on data from the general population in the same geographic area. Routine HBV and HCV serological testing did not contribute substantially to the diagnosis of recent-onset polyarthritis. Although advisable before initiating immunosuppressive or hepatotoxic drugs, serological testing for HCV and HBV is unnecessary in routine diagnostic evaluation of recent-onset polyarthritis.

Abstract: OBJECTIVE: To assess the usefulness of using oblique foot radiographs in addition to posteroanterior radiographs of the hands and feet for detecting erosions in patients with recent-onset arthritis. METHODS: We included 813 patients from the prospective French ESPOIR cohort with arthritis of <6 months' duration and >or=2 swollen joints. Baseline standardized posteroanterior radiographs of the hands and feet and oblique radiographs of the feet were assessed by 2 blinded readers for erosions typical for rheumatoid arthritis (ETRA) and the Sharp score as modified by van der Heijde. RESULTS: A total of 715 complete sets were available. Mean +/- SD total Sharp scores were 3.6 +/- 6.6, 2.5 +/- 6.3, and 1.8 +/- 5 for the hand and wrist, foot, and oblique foot, respectively. ETRA were visible in 160 (22.4%) of 715 patients (95% confidence interval [95% CI] 19.4-25.6). They were seen on hand radiographs in 86 (53.7%) of 160 patients (95% CI 45.7-61.6), on posteroanterior foot radiographs in 91 (56.9%) of 160 patients (95% CI 48.8-64.6), and on oblique foot radiographs in 84 (52.5%) of 160 patients (95% CI 44.5-60.4). ETRA were visible at the feet, but not at the hands, in 74 (46%) of 160 patients (95% CI 38.4-54.3), among whom 22 (30%) had erosions only on the posteroanterior view, 16 (21%) only on the oblique view, and 36 (48.6%) on both. CONCLUSION: ETRA were found in 22.4% of patients. Adding an oblique foot radiograph identified 16 (10%) of 160 additional patients (95% CI 6-16), compared with 27.5% and 13.8% identified by adding posteroanterior radiographs of the hands and feet, respectively.

Abstract: OBJECTIVE: To evaluate clinical, laboratory, and radiological features and outcomes in patients with monoarthritis (MA), identified in a cohort of patients with early arthritis. METHODS: A cohort of 270 patients with undiagnosed arthritis of less than 1 year's duration was divided into 3 groups: single episode of MA (MA, n = 27), MA with a history of patient-reported arthritis (MA + past, n = 23), and oligo- or polyarthritis (OA/PA, n = 220). At 6-month intervals, all patients underwent a standardized examination, radiographs, and standard laboratory tests including rheumatoid factors (RF), antiperinuclear factor (APF), antikeratin antibody (AKA), anticyclic citrullinated peptide antibody (anti-CCP), antinuclear antibodies, and HLA-AB-DR typing. After a median followup of 30 months, the diagnosis was evaluated by a hospital-based rheumatologist. RESULTS: Age and sex did not differ across the 3 groups. Knee involvement was more common in the MA group than in the MA + past group (p < 0.03), whereas hand and metatarsophalangeal involvement was less common (p < 0.03 and p < 0.0001, respectively). RF and anti-CCP were less often positive in the MA group than in the MA + past group (p < 0.02 and p < 0.001, respectively) and the OA/PA group (p < 0.02 and p < 0.03). No patient in the MA group received a diagnosis of rheumatoid arthritis (RA). RA was less common and disease modifying antirheumatic drugs were prescribed less often in the MA group than in the other 2 groups (p < 0.0001 for both comparisons). CONCLUSION: The MA group was clearly different from the other groups, with a favorable outcome and no risk of progression to RA.

Abstract: OBJECTIVE: To evaluate the proportion of patients with rheumatoid arthritis (RA) visiting office-based rheumatologists for persistently active RA despite past or current methotrexate (MTX) treatment, and to describe the management of these patients in France in 2003. METHODS: All French rheumatologists were invited to participate in a cross-sectional postal survey. During a predetermined week, they were to include the first 2 patients seen for RA with a history of past or current MTX treatment. Adequacy of current treatment was assessed based on the 28-joint Disease Activity Score 28 (DAS28) and on current MTX and corticosteroid regimens. RESULTS: Of the 1800 French rheumatologists, 492 returned 838 assessable patient questionnaires. Mean patient age was 58 years and mean time since RA diagnosis was 10 years; 77% of patients were currently taking MTX, and 51% a corticosteroid. High dosages were noted for MTX (> 15 mg/week) in 20% of patients and for corticosteroid therapy (> 10 mg/day) in 5%. Nevertheless, 41% of patients had active RA (DAS28 score 3.2 to 5.1) and 7% had very active RA (DAS28 score > 5.1). The treatment was left unchanged in 78% of patients, and biological therapy was contemplated in only 16% of patients. CONCLUSION: Although half of MTX-treated patients with RA visiting office-based rheumatologists had active or very active disease, a change in treatment was rarely considered.

Abstract: OBJECTIVE: To evaluate the ability of baseline hand radiographs to predict the diagnosis 2 years later in a cohort of patients with early arthritis. METHODS: A total of 258 patients with arthritis onset within the previous year were evaluated. At baseline, all patients underwent a standardized evaluation including laboratory tests and radiographs. Hand radiographs were read by a blinded observer who used a standardized procedure for detecting features of crystal deposition diseases and rheumatoid arthritis (RA). After 30 +/- 11.3 months, the final diagnosis was established by a panel of rheumatologists. All radiographs were evaluated. RESULTS: Significant associations were found between radiographic features and a clinical diagnosis of RA, calcium pyrophosphate dihydrate (CPPD) arthritis, and hydroxyapatite arthritis. No radiographic abnormalities suggesting psoriatic arthritis or gout were seen. The sensitivities of hand radiographs for diagnosing CPPD or hydroxyapatite arthritis ranged from 80% to 100%. Baseline hand radiographs suggested the final diagnosis in 31/258 patients, including 21 (22.5%) of the 93 patients with RA, 10 of the 11 (91%) patients with CPPD or hydroxyapatite deposition disease, and none of the patients with other disorders. Sensitivity was 29%, specificity 86.5%, positive predictive value 61%, and negative predictive value 63%. CONCLUSION: In our cohort of patients with recent arthritis, the overall performance of hand radiographs in predicting a diagnosis 2 years later was modest. However, they had an excellent diagnostic value for calcium deposition diseases.

Abstract: OBJECTIVE: To correlate the periodontal status of 15 patients with primary Sjögren's syndrome (SS) with their salivary levels of BAFF. METHODS: The periodontal status of 15 patients who fulfilled the criteria for primary SS was compared with that of 15 controls with xerostomia who did not fulfill the criteria for primary SS but had similar symptoms of dry mouth. The level of BAFF was measured in paired samples of saliva and serum using in-house enzyme-linked immunosorbent assays. Periodontitis was assessed by the plaque index, the modified gingival index, the papillary bleeding index, and the periodontal pocket depth. RESULTS: Notwithstanding the better oral hygiene practices of the patients with primary SS compared with those of the xerostomia controls and the subsequent reduction of their plaque index scores, complications of periodontitis, such as bleeding, gingival hypertrophy, and periodontal pockets, were not improved. This failure to ameliorate the complications of periodontitis in patients with primary SS was associated with high levels of BAFF in their saliva compared with the levels in xerostomia controls (7.4 +/- 2.1 versus 1.0 +/- 0.4 ng/ml [P < 0.002]). The levels of BAFF in saliva did not correlate with the levels in sera but did correlate with the periodontal pocket depth (P < 0.002). CONCLUSION: These findings are similar to the bone resorption observed in patients with rheumatoid arthritis. They suggest that the known effect of B cells in periodontitis would be partly mediated by salivary BAFF in patients with primary SS.
