Abstract: OBJECTIVE: The objective of this study was to determine the time to relapse after tumor necrosis factor alpha (TNFalpha) antagonist discontinuation in patients with remission of rheumatoid arthritis (RA). METHODS: Among 304 patients taking TNFalpha antagonist therapy for RA, 21 achieved a remission and were taken off the TNFalpha antagonist. Remission was defined as DAS28<2.6 for at least 6 months without nonsteroidal inflammatory drugs or more than 5 mg of prednisone per day but with disease-modifying antirheumatic drug (DMARD) therapy if needed. The same TNFalpha antagonist was restarted in the event of a relapse (DAS28>3.2). RESULTS: The 21 patients had a mean age of 61 years, a mean disease duration of 11.3 years, and a mean remission duration at TNFalpha antagonist discontinuation of 19.2 months. The TNFalpha antagonist was infliximab in 2 patients, adalimumab in 5, and etanercept in 14; and 14 patients were taking a concomitant DMARD. The number of patients still in remission after TNFalpha antagonist discontinuation was 9/20 after 6 months and 5/20 after 12 months. Mean time to relapse was 14.7 weeks. While off TNFalpha antagonist therapy, 3 of the 5 relapse-free patients after 12 months were on DMARD therapy, compared to 11 of the 15 patients who relapsed. Compared to the 15 patients who relapsed, the 5 relapse-free patients had a longer time on TNFalpha antagonist therapy (56 months vs. 35 months, P=0.012) and a longer time in remission on TNFalpha antagonist therapy (35 months vs.14.5 months, P=0.04). The 15 patients who relapsed consistently achieved a remission after resuming TNFalpha antagonist therapy; the remission occurred within 2 months in 13 patients. CONCLUSION: TNFalpha antagonist discontinuation in patients in remission of RA was followed by a relapse within 12 months in 75% of cases. Relapsing patients responded well to resumption of the same TNFalpha antagonist.

Abstract: OBJECTIVE: Patients with severe rheumatoid arthritis and resistant to at least three DMARDS can benefit from anti-TNFalpha (tumor necrosis factor) therapy. In some patients, because of inefficacy or adverse events, treatment with one of the two available TNFalpha drugs (etanercept and infliximab) must be stopped. In this study, we explored the results in efficacy and tolerance of switching from one anti-TNFalpha to the other.PATIENTS: Between August 1999 and January 2002, we administered one of the two anti TNFalpha drugs to 131 patients: 67 patients received infiximab and 64 etanercept.RESULTS: Among the 67 patients treated with infliximab, 17 patients had to stop treatment. In 8 of them (4 allergies, 2 infections and 2 non responders) the switch from infliximab to etanercept was beneficial for 5 patients, 2 patients did not respond and 1 patient withdrew for personal reasons. Among the 64 patients treated with etanercept, 13 had to stop treatment. In 6 of them (2 adverse events, 4 failures) the switch from etanercept to infliximab was beneficial for 3 patients, 2 did not respond and 1 withdrew because of adverse events.CONCLUSION: In all, 14 patients with severe rheumatoid arthritis and treated by one of the two TNFalpha drugs (and in whom treatment was stopped because of adverse events or inefficacy) benefited from the switch to the other anti- TNFalpha, with excellent response in 8 out of 14 patients.
