Abstract
-
Sulfasalazine, one of disease modifying anti-rheumatic drugs, is widely used in various rheumatic diseases. Very rarely, sulfasalazine causes drug-associated hypersensitivity syndrome that resembles infectious mononucleosis. Clinical signs include fever, lymphadenopathy, maculopapular skin rash and multivisceral involvement which appear 2 to 5 weeks after administration of drug. Atypical lymphocytosis, liver dysfunction and splenomegaly are also frequently observed. Severe infectious mononucleosis-like syndrome in sulfasalazine treated patients can be caused by reactivation of viruses such as human herpes virus-6, that often result in hypersensitivity syndrome. We report a case of patient who developed infectious mononucleosis-like syndrome after administration of sulfasalazine for the treatment of rheumatoid arthritis. This case warrents careful observation for infectious mononucleosis-like syndrome after sulfasalazine treatment.
