Purpose: To describe a series of 5 patients with herpes simplex virus keratitis (HSK) and rheumatoid arthritis (RA) under immunosuppressive treatment.
Methods: Retrospective study. Detailed data were obtained regarding symptoms and signs at the initial evaluation, treatment, microbiological diagnostic tests, evolution, and outcomes.
Results: Five patients with HSK and RA were identified. Bilateral involvement occurred in 2 patients (40%). Epithelial keratitis was diagnosed in 5 eyes. Three eyes showed severe melting with eye perforation. Gram-positive bacterial co-infections were common in the group with stromal keratitis. We did not find differences in the evolution of the disease based on anti-rheumatoid treatment.
Conclusions: The characteristics of HSK in patients with RA differed from HSK in immunocompetent patients. The stromal keratitis cases were very aggressive and difficult to manage, with perforation and gram-positive bacterial co-infection as frequently associated conditions. Prophylactic therapy at standard doses was unsuccessful to avoid recurrences.
