The Dilemma of Balancing Anti-Tumor Necrosis Factor-Alpha (Anti-TNF-α) Biologics for Psoriatic Arthritis Control With the Risk of Severe Systemic Infection.

The treatment landscape for psoriatic arthritis (PsA) has evolved significantly with the introduction of biologic therapies, such as adalimumab, which effectively inhibits tumor necrosis factor-alpha (TNF-α) activity. However, despite their efficacy in controlling inflammation, biologic therapies are associated with heightened risks of infectious complications and malignancies. We present a case of a 66-year-old female with PsA treated with adalimumab who presented with recurrent systemic bacterial infections. Despite attempts to adjust dosing intervals to minimize infection risks, the patient experienced severe complications, including urosepsis, endocarditis, and liver abscesses. The dilemma arises in balancing PsA control with anti-TNFα therapy while minimizing infection risks. Current evidence supporting prophylactic antibiotics in such cases is limited, and determining the next steps for treatment involves challenging decisions such as withholding TNF inhibitors or switching to alternative immunomodulators. This case underscores the need for further research into prophylactic treatment and monitoring protocols to manage recurrent infections during anti-TNF-α therapy effectively.
