Efficacy of Anti-TNF Agents as Adjunctive Therapy for Knee Synovitis Refractory to Disease-Modifying Antirheumatic Drugs in Patients with Peripheral Spondyloarthritis (original) (raw)

Our aim was to evaluate the effectiveness of tumour necrosis factor (TNF) inhibitors as add-on therapy for knee synovitis that did not respond to disease-modifying antirheumatic drugs (DMARDs) and other standard treatments in patients with peripheral spondyloarthritis (SpA). We retrospectively studied 27 SpA patients, in whom an anti-TNF agent was added for active peripheral arthritis with knee synovitis refractory to DMARDs and treatment with low-dose oral corticosteroids and/or nonsteroidal anti-inflammatory drugs (NSAIDs) and intra-articular (IA) corticosteroids. As response of knee synovitis, were considered the absence of swelling, tenderness, and decreased range of movement in the clinical examination, after 4 months of anti-TNF therapy. In twenty-four (88.9%) of the patients there was response of knee synovitis. No statistical differences in gender (P = 0.53), age (P = 0.88), disease subtype (P = 0.22), and pattern of arthritis (P = 0.20) between knee synovitis responders and...
