Discontinuation of TNF-alpha Inhibitors in Patients With Spondyloarthritis
Discontinuation of TNF-alpha Inhibitors in Spondylarthritis Patients With Low Disease Activity, and Re-initiation of Therapy if Disease Flares

Spondylarthropathy (SpA) comprises a group of rheumatic diseases mainly affecting the spine and sacroiliac joints. In most of the patients disease activity alternates, and some patients have symptom free periods. Tumor-Necrosis-Factor-alpha (TNF-alpha) antagonists have significantly improved the treatment options for patients with spondyloarthritis. TNF-alpha antagonist therapy is costly, implies an increased risk of infections, including reactivation of tuberculosis, and the risk of long-term adverse events, as cancer, is fully clarified. It is highly relevant to explore to which extent anti-TNF-alpha therapy can be discontinued in SpA patients without immediate relapse of disease activity. Two studies have investigated discontinuation of a TNF-alpha antagonist (infliximab and etanercept) in ankylosing spondylitis, reporting flares in the majority of patients within the 1-year follow-up period, with the longest times to relapse in patients with the lowest disease activity. The effect of adalimumab discontinuation has never been studied, and, furthermore, the effect of TNF-alpha-antagonist discontinuation has never been studied in patients with early spondyloarthritis not fulfilling the New York criteria.
