Comparative StudyObservational study of switching anti-TNF agents in ankylosing spondylitis and psoriatic arthritis versus rheumatoid arthritis.
Anti-TNF agents like infliximab, etanercept and adalimumab are efficacious in the treatment of ankylosing spondylitis (AS), psoriatic arthritis (PsA) and rheumatoid arthritis (RA). Lack of efficacy, side effects and loss of efficacy over time may be reasons for switching to a second anti-TNF agent and sometimes switching to a third anti-TNF agent may be useful. Effects of switching may be different in patients with AS, PsA and RA. ⋯ Switching anti-TNF agents for loss of efficacy over time may have the best effect in patients with AS, PsA and predominantly in RA. Our data suggest that switching for lack of efficacy in RA patients cannot be recommended, but may be an alternative in patients with AS and PsA. Switching to a second anti-TNF agent for side effects may be reasonable, switching to a third anti-TNF agent again for side effects cannot be recommended.
