Ibuprofen-induced meningitis in mixed connective tissue disease.

A young Black woman with mixed connective tissue disease (MCTD) developed an aseptic meningitis after receiving ibuprofen. The meningeal reaction, reported infrequently in systemic lupus erythematosus (SLE) and only once previously in MCTD, was characterized by a predominantly polymorphonuclear cerebrospinal fluid (CSF) pleocytosis and depression of CSF glucose. Reversible renal insufficiency also occurred. Features suggestive of a hypersensitivity reaction included pruritus, conjunctivitis, facial oedema, desquamation of the palms and soles, and subsequent near total alopecia. Meningeal signs responded rapidly to systemic corticosteroid therapy. Patients with MCTD as well as those with SLE may be at peculiar risk of developing this uncommon reaction to ibuprofen.
