Abstract: Anti-cyclic citrullinated antibodies occurrence is a recent serological marker for rheumatoid arthritis. The aim of our study was to evaluate the measurement of these antibodies by a new fluorescent-enzyme immunoassay, called EliA CCP, fully automated onto UniCAP 100. This evaluation reveals correct and shows a within run imprecision of 4.6 to 10.5 % and a between-assay imprecision of 9,5 %. The comparison with an Elisa method (Euroimmun) shows a good correlation of anti-CCP concentrations without any major discrepancy.

Abstract: OBJECTIVE: Adult Still's disease (ASD) is a rare chronic polyarthritis, usually treated with corticosteroid therapy. Because some patients become dependent on high dose prednisone or are refractory to that treatment, and because adverse events are frequent with corticosteroid, we evaluated the efficacy of low dose methotrexate (MTX) as a second-line drug. METHODS: We retrospectively studied 26 patients with ASD treated with low dose MTX because their disease was either resistant to or dependent on corticosteroids. RESULTS: The group included 13 women and 13 men, with a mean age of 32.6 years at onset of ASD. Mean disease duration at the beginning of MTX treatment was 59.9 mo (range 7 to 444). Evaluation took place at the maximum followup, which averaged 48.9 mo (range 8 to 136). The mean dose of MTX was 11.5+/-3.6 mg/week (range 7.5 to 17.5). Twenty-three patients responded to MTX; 18 had complete remission. No difference was seen between patients with or without extraarticular manifestations. Leukocyte and neutrophil counts and erythrocyte sedimentation rate were significantly reduced (p = 0.0001). Daily prednisone intake decreased by 69% (21.5 mg) (p = 0.0001). Eleven patients were able to stop taking corticosteroids. One patient with AA amyloidosis renal failure died of neutropenia: this was the only serious adverse event. CONCLUSION: MTX is an effective second-line treatment of ASD that does not respond to prednisone. It allows significant reduction of corticosteroid doses, which is beneficial to these patients, who have frequent and numerous corticosteroid related adverse events.

Abstract: OBJECTIVES: To elaborate a how-to-use abatacept material intended to help physicians in the management of patients with inflammatory diseases treated with this drug in routine practice. METHODS: 1) Selection of the relevant domains by a rheumatologists' panel; 2) Search for published evidence in each domain; 3) Elaboration of the clinical tool guide with a 3-level gradation of evidence (evidence-based medicine EBM, official recommendations and expert's opinion). The experts were 11 academic rheumatologists with a large experience in prescribing abatacept and in managing rheumatoid arthritis. They were all members of the CRI (Club Rhumatismes et Inflammation), a section of the French Rheumatology Society dedicated to the inflammatory rheumatic diseases. Each fact sheet was reviewed by two other experts; 4) Regular updating based on medical literature and postmarketing surveillance data. RESULTS: Four domains were considered relevant: abatacept contraindications, management of side effects or associated diseases appearing during abatacept treatment, management of "practical situations" such as surgery or pregnancy, physician and patient information. After the literature analysis and discussion during an experts' meeting, a consensus was reached on: a pre-treatment checklist aimed at searching abatacept contraindications; a what-to-do document when facing side effects or associated diseases (autoimmune pathology, bacterial or viral infections, cardiovascular diseases, intolerance to abatacept, solid or haematological malignancy) or "practical situations" (surgery, pregnancy, vaccination, travel, drug-drug interactions); an example of standard information letter to be addressed to the attending physician (rheumatologist and general practitioner); an example of standard information letter to be addressed to the patient. CONCLUSION: Based on both an EBM approach and an expert's opinion approach, this abatacept clinical tool guide should provide assistance to all physicians attending patients treated with abatacept. For a better implementation in clinical practice, this tool guide will be available online at www.cri-net.com and regularly updated.

Abstract: OBJECTIVES: to evaluate specificity and sensibility of the rheumatoid factors (RF), the anti-cyclic citrullinated peptide antibodies (CCP) and the anti-keratin antibodies (AKA) according to the rheumatoid arthritis (RA) diagnosis; pathology other than RA with at least one of these marker positive; the significance of the flocculent fluorescence of the antibodies AKA by indirect immunofluorescence (IIF). METHOD: two hundred forty height patients were studied: 121 RA, 89 inflammatory rheumatisms, 23 non inflammatory rheumatisms, and 15 non rheumatic affections. The RF was investigated by nephelometry, the anti-CCP by immunofluorometry and the AKA by IIF on rat oesophagus. RESULTS: specificity and sensibility were respectively in a retrospective manner: 68% and 83% for the RF, 95% and 76% for the anti- CCP, 83% and 40% for the AKA during RA with evolution of less than one year. The rates of agreements were: RF versus CCP: 81%, RF versus AKA: 57%, CCP versus AKA: 73%. Twelve patients with pathologies different from RA have positive anti-CCP or AKA. Thirty three of the patients with anti-CCP level superior to 130 U/mL have flocculent AKA versus only 5% when the anti-CCP are lower than 130 U/mL. CONCLUSION: the RF and the anti-CCP are complementary in RA. Autoimmune and neoplasic pathologies are sometimes responsible for the positivity of the anti-CCP and the AKA. The flocculent aspect of AKA in IIF may be associated with raised concentrations of anti-CCP.

Abstract: OBJECTIVE: To determine geographical variation in the prevalence of rheumatoid arthritis (RA) and spondyloarthropathies (SpA) in France. METHODS: The survey sample was drawn from 7 areas of France. Households were randomly selected using the national telephone directory, and an individual within each household was randomly chosen by the next-birthday method. All cases of suspected RA and SpA were confirmed by the patient's rheumatologist or by clinical examination. Standardized estimates of prevalence were compared between regions and groups of regions. RESULTS: In total 15,219 anonymous telephone numbers were selected. An average response rate of 64% led to a total of 9395 respondents included in the study. The highest regional rates of RA were observed in the south (range 0.59-0.66%), and the lowest in the north (range 0.14-0.24%), with a national rate of 0.31% (95% CI 0.18-0.48%). Regional heterogeneity was observed for SpA, with the highest rates in Bretagne (0.47%) and the Sud-Est (0.53%) and a national rate of 0.30% (95% CI 0.17-0.46%). CONCLUSION: This study is the largest of its kind conducted in France. It shows inter-regional variations, mainly in RA, with a higher prevalence in the south of the country. The many potential reasons for the heterogeneity observed, including genetic and environmental factors, warrant further research.

Abstract: OBJECTIVE: To investigate the safety and efficacy of rituximab (RTX) for systemic symptoms in patients with primary Sjögren's syndrome (pSS), and changes in B cell biomarkers. PATIENTS AND METHODS: The records of 16 patients with pSS according to the American European consensus group criteria were reviewed retrospectively. RESULTS: Patients, all women, had a median age of 58.5 (range 41-71) years and a disease duration of 9.5 (range 0-25) years. RTX was prescribed for lymphoma (n = 5), refractory pulmonary disease with polysynovitis (n = 2), severe polysynovitis (n = 2), mixed cryoglobulinaemia (n = 5), thrombocytopenia (n = 1) and mononeuritis multiplex (n = 1). The median follow-up duration was 14.5 (range 2-48) months. Three patients experienced adverse events, including one mild serum sickness-like reaction with the presence of human antichimeric antibodies. Efficacy of treatment was observed in 4 of 5 patients with lymphomas and in 9 of 11 patients with systemic involvement. Dryness was improved in only a minority of patients. Corticosteroid dose was reduced in 11 patients. RTX induced decreased rheumatoid factor, gamma-globulin and beta2-microglobulin levels, and the level of B cell activating factor of the tumour necrosis factor family (BAFF) increased concomitantly with B cell depletion. Five patients were re-treated, with good efficacy and tolerance, except for one with probable serum sickness-like reaction. CONCLUSION: This study shows good efficacy and fair tolerance of RTX for systemic features. In addition, RTX allows for a marked reduction in corticosteroid use. Except for BAFF, the level of which increases, serum B cell biomarker levels decrease after taking RTX. Controlled trials should be performed to confirm the efficacy of RTX in pSS.

Abstract: OBJECTIVE: To estimate the prevalence of spondyloarthropathies (SpAs) in France in a multiregional representative sample in the year 2001. METHODS: A two stage random sample was constituted in seven areas from the national telephone directory and the next birthday method in each household. Interviewers were patient-members of self help groups trained to administer telephone surveys using a validated questionnaire for detecting inflammatory joint disease. Quality of data collection was controlled periodically. SpA was confirmed by the patient's rheumatologist or by clinical examination. Prevalence estimates after probability sampling correction were standardised for age and sex (1999 national census). RESULTS: Among the 15 219 anonymous telephone numbers selected, 3.6% were places of work or secondary residences and were excluded. The phone interview participation rate ranged across regions from 55.1 to 69.9%. 3554 men and 5841 women were included in the study. Twenty nine cases of SpA were confirmed. All but one fulfilled ESSG criteria. Mean age was 47 years (range 21-78). The overall prevalence standardised for age and sex was 0.30% (95% confidence interval (CI) 0.17 to 0.46). Prevalence was similar in women (0.29% (95% CI 0.14 to 0.49)) and men (0.31 % (95% CI 0.12 to 0.60)). Geographical analysis by department clustering found no significant differences. The prevalence of SpA was as high as that of rheumatoid arthritis. CONCLUSION: Prevalence of SpA in France was 0.30% in 2001, with no difference between women and men. Ankylosing spondylitis and psoriatic arthritis were the most common SpA subsets.

Abstract: BACKGROUND: Prevalence estimates of rheumatoid arthritis (RA) vary across Europe. Recent estimates in southern European countries showed a lower prevalence than in northern countries. OBJECTIVES: To estimate the prevalence of RA in France in a multiregional representative sample in the year 2001. METHODS: A two stage random sample was constituted in seven areas (20 counties) from the national telephone directory of households and by the next birthday method in each household. Patient-interviewers, member of self help groups, were trained to administer telephone surveys using a validated questionnaire for case detection of inflammatory rheumatism, and conducted the survey under quality control. All suspected cases of RA were confirmed by their rheumatologist or by clinical examination. Prevalence estimates after probability sampling correction were standardised for age and sex (national census 1999). RESULTS: An average response rate of 64.7% (two stages combined) led to a total of 9395 respondents. Standardised prevalence was 0.31% (95% confidence interval 0.18 to 0.48) for RA, 0.51% in women and 0.09% in men, with a higher age-specific prevalence in the 65-74 year age band. A geographical analysis of county clustering showed significant variation across the country. CONCLUSION: This national multiregional cooperative study demonstrates the usefulness of working in association with patients of self help groups. It showed a similar prevalence of RA to that of the spondyloarthropathies estimated concomitantly during the survey. It provides a reliable basis for definition of population targets for healthcare delivery and drug treatments.

Abstract: OBJECTIVE: To assess the tolerance and efficacy of rituximab in patients with various autoimmune diseases seen in daily rheumatological practice. METHODS: 866 rheumatology and internal medicine practitioners were contacted by e-mail to obtain the files of patients treated with rituximab for systemic autoimmune diseases. Patients with lymphoma were analysed if the evolution of the autoimmune disease could be evaluated. RESULTS: In all, 43 of 49 cases could be analysed, including 14 with rheumatoid arthritis (RA), 13 with systemic lupus erythematosus (SLE), six with primary Sjogren's syndrome (pSS), five with systemic vasculitis, and five with other autoimmune diseases. Rituximab was prescribed for lymphoma in two patients with RA and two with pSS. In the 39 other cases, rituximab was given because of the refractory character of the autoimmune disease. The mean follow up period was 8.3 months (range 2 to 26). There were 11 adverse events in 10 patients and treatment had to be discontinued in six. Efficacy was observed in 30 patients (70%): RA 11, SLE 9, pSS 5, vasculitis 2, antisynthetase syndromes 2, sarcoidosis 1. The mean decrease in corticosteroid intake was 9.5 mg/d (range 0 to 50) in responders. Seven patients experienced relapse after mean 8.1 months (5 to 15). Three patients died because of refractory autoimmune disease. CONCLUSIONS: Despite absence of marketing authorisation, rituximab is used to treat various refractory autoimmune diseases in daily rheumatological practice. This study showed good tolerance and short term clinical efficacy, with marked corticosteroid reduction in patients with SLE, pSS, vasculitis, and polymyositis.

Abstract: OBJECTIVE: To evaluate agreement between a rheumatologist visit and a telephone interview by a patient organization member, regarding the diagnosis of rheumatoid arthritis (RA) or spondyloarthropathy (SpA) and the classification criteria for these two conditions. METHOD: Patients underwent a standardized interview and physical examination by hospital-based rheumatologists, who diagnosed RA in 230 cases, SpA in 175, and other conditions (controls) in 195. Members of patient organizations then used a standardized questionnaire to interview the patients by telephone about their diagnosis and about 1987 ACR classification criteria for RA and the ESSG criteria for SpA. RESULTS: Agreement between the two sources of data was poor for the classification criteria but satisfactory for the diagnosis (kappa, 0.84 (0.81-0.87) for RA and 0.78 (0.75-0.81) for SpA). CONCLUSION: Standardized telephone interviews conducted by patient organization members accurately identify the diagnosis made by rheumatologists based on a physical examination and medical record review, whereas agreement is poor regarding classification criteria for RA and SpA.
