(1) To describe a case of necrotizing group A streptococcal periorbital infection in a patient receiving treatment with adalimumab (Humira, Abbott)-- a fully humanized monoclonal anti-TNF-α agent. (2) To identify bacterial species responsible for infection with different forms of biological therapy.
Single interventional case report and literature review.
A 57-year-old woman developed severe right-sided necrotizing periorbital infection whilst receiving treatment with adalimumab for rheumatoid arthritis (RA). Cultures grew Lancefield Group A Streptococcus pyogenes. An extensive literature search for reports of ocular infections associated with biological therapy was conducted.
Adalimumab therapy was discontinued and the patient was admitted to an intensive care unit. The patient made a complete recovery after receiving appropriate antibiotic therapy. Overall Gram-positive cocci are the most common infection associated with use of biological therapy.
Anti-TNF-α agents are powerful immune-modulating drugs with potentially serious side effects. This case is the first to link adalimumab to necrotizing periorbital infection. Resolved infection does not preclude reintroduction of anti-TNF therapy however, careful assessment of the risks versus benefits of therapy is required at the individual patient level.
