To present the data supporting the possible relationship of ocular toxoplasmosis to antitumor necrosis factor-alpha (TNF-alpha) therapy in patients with rheumatoid arthritis (RA).
A Medline search was performed using the words "toxoplasmosis, anti-TNF-alpha antagonists, chorioretinitis." We report 2 RA patients who developed ocular toxoplasmosis while receiving anti-TNF-alpha therapy.
In addition to our patients with toxoplasmic chorioretinitis, there are 2 published cases of cerebral toxoplasmosis during treatment with anti-TNF-alpha agents.
The risk of serious toxoplasmic infection during anti-TNF-alpha therapy for RA should be recognized.
