Abstract: OBJECTIVE: To update French Society for Rheumatology guidelines regarding the use of tumor necrosis factor alpha (TNFalpha) antagonists for treating patients with ankylosing spondylitis (AS) or psoriatic arthritis (PsA). METHODS: We used the method recommended by Shekelle et al. to update the original recommendations: a limited group of experts selected the items that required updating, the relevant literature was critically appraised, and the experts developed new wording for the recommendations, which was then subjected to internal and external validation. As with the original recommendations, three topics were addressed, namely, indications of TNFalpha antagonist therapy, treatment initiation, and treatment adjustment and follow-up. RESULTS: Four criteria should be used to evaluate the indication of TNFalpha antagonist therapy. First, the patient must have a definitive diagnosis of AS or PsA. Thus, patients with AS must meet modified New York criteria or exhibit characteristic involvement of the sacroiliac joints, spine, or peripheral sites documented by radiographs or computed tomography (structural damage) or by magnetic resonance imaging (inflammation). Patients with PsA must meet validated criteria such as the Moll and Wright or CASPAR criteria. The second criterion is active disease for more than 1month, with a BASDAI >or=4 in patients with predominantly axial disease or a tender/swollen joint count >or=3, and with a physician assessment of disease activity of >or=4/10. The third criterion is failure of at least three non-steroidal anti-inflammatory drugs in patients with axial disease or of disease-modifying antirheumatic drug (DMARD) therapy (methotrexate, salazopyrine, or leflunomide) in patients with peripheral disease. Fourth, the patient must be free of contraindications to TNFalpha antagonist therapy. Four recommendations pertain to the initiation of TNFalpha antagonist therapy: a workup should be performed prior to treatment initiation; there is no evidence that one TNFalpha antagonist is more effective than the others, so decisions about drug selection should be shared with the patient and guided by available safety data and the patient's profile; there is no proof that greater effectiveness can be achieved by routinely combining a conventional DMARD; and patients should receive regular standardized follow-up. The last four recommendations deal with adjusting TNFalpha antagonist therapy: the treatment objective is a 2-point or greater improvement in the BASDAI in patients with axial disease and a 30% or greater improvement in the tender/swollen joint counts in patients with peripheral disease; there is no evidence to support the introduction of DMARD therapy in non-responders, who can be switched to another TNFalpha antagonist or, when on infliximab, given higher dosages or more closely spaced injections; patients who fail to tolerate one TNFalpha antagonist can be switched to another TNFalpha antagonist if allowed by the nature of the adverse event; and when a remission is achieved, reduction or discontinuation of concomitant anti-inflammatory therapy should be considered, followed in the event of a prolonged remission by a reduction in the dosage of the TNFalpha antagonist.

Abstract: The diagnosis of early arthritis is often difficult even though it is an important issue. A step-by-step clinical examination is necessary to make the diagnosis of "joint emergency": an infection must be suspected when fever is associated with arthritis. Then, classification of early arthritis will be carried on with a special attention to rheumatoid arthritis when the rheumatism is persistent and erosive. However, arthritis might be undifferentiated for several months to years; such an explanation should be given to the patient. A tight follow-up is necessary.

Abstract: OBJECTIVES: Several paradoxical adverse events (PAEs), e.g. IBDs, acute anterior uveitis (AAU) and psoriasis, have been described in patients taking anti-TNF drugs. This retrospective study aimed to describe the different PAEs that have occurred in a population of SpA patients treated with anti-TNF drugs, and to determine whether they are drug specific. METHODS: Since 2000, we have followed 296 patients with SpA [198 AS, 21 SpA associated with IBD (9 ulcerative colitis, 12 Crohn's disease) and 77 psoriatic arthritis] treated with at least one anti-TNF drug (infliximab, etanercept or adalimumab), and 112 SpA patients treated only with conventional DMARDs who served as controls. Considering the cumulative time of exposure to each anti-TNF agent, the frequencies of new-onset PAEs in exposed patients were calculated. RESULTS: Respective cumulative exposure times were 287, 290 and 62 patient-years for infliximab, etanercept and adalimumab. We observed the following PAEs: five psoriasis (three under infliximab and one with etanercept or adalimumab), three AAU (1/100 patient-years, all under etanercept) and four IBD (three under etanercept and one under infliximab). There was no significant association among any of these PAEs and a specific anti-TNF agent; nor significant difference in the overall PAEs among patients receiving anti-TNF drugs or controls (P = 0.303), the latter experiencing two psoriasis and three AAU. CONCLUSIONS: Undesirable side effects--IBD, AAU and psoriasis--may appear with anti-TNF drugs. Even if they are, a priori, paradoxical, no evidence supports any PAEs to be anti-TNF agent-specific in SpA.
