Introduction: Psoriatic arthritis (PsA) is a chronic inflammatory condition involving the spine, enthesis and peripheral joints, which is associated with psoriasis. PsA therapy varies from use of NSAIDs to disease-modifying anti-rheumatic agents (DMARDs). However, their use can represent a limitation in patients with concomitant hepatitis C virus (HCV) infection. In the last few decades, anti-TNF-α therapy has opened new horizons in the treatment of PsA. Hence, the purpose of this review is to explore the efficacy and safety of anti-TNF-α agents in PsA and concomitant HCV infection.
Areas covered: We reviewed the available medical literature to find all cases of PsA and concomitant HCV infection treated with TNF-α inhibitors. We found a total of 38 cases of patients with PsA and concomitant HCV infection in therapy with anti-TNF-α agents.
Expert opinion: The available literature, summarized in this review, still remains very limited. Data suggest that therapy with the anti-TNF-α agents, mainly etanercept and adalimumab, at least with short-term use, would appear efficacious and reasonably safe in the management of PsA patients with concomitant HCV infection. With regard to infliximab, efficacy and safety have been scarcely explored, whereas in the case of golimumab and certolizumab no report was found, may be due to their recent introduction on the market.
