Ibuprofen-induced fever in Sjogren's syndrome.

A 68-year-old woman with a medical history significant for Sjögren syndrome and leukocytoclastic vasculitis of small vessels presented to the emergency department with chills, malaise, a temperature of 39 degrees C, nausea, vomiting, and hypotension. Fifteen minutes earlier she had taken ibuprofen for flu-like symptoms. She was treated with a perfusion of intravenous saline, paracetamol, and ciprofloxacin with improvement 24 hours later. Three months later, she had a similar episode, without hypotension. An oral challenge test with ibuprofen in the hospital produced the same symptoms 3 hours after the last dose. She was treated with metamizole and paracetamol and was asymptomatic the next day. This is the first report of a febrile reaction to ibuprofen in a patient with Sjogren's syndrome.
