Corticosteroids, ibuprofen, and acetaminophen for IFNbeta-1a flu symptoms in MS: a randomized trial.

概要
OBJECTIVE
To compare the efficacy of acetaminophen, ibuprofen, and prednisone in the treatment of interferon beta-1a (IFNbeta-1a) flu-like syndrome (FLS).
METHODS
Patients with relapsing-remitting multiple sclerosis initiating treatment with IM IFNbeta-1a were randomized in a multicenter, randomized, double-blind, controlled trial to receive acetaminophen 500 mg before and 6 and 12 hours after each injection, ibuprofen 400 mg before and 6 and 12 hours after each injection, or prednisone 60 mg daily for 1 week, plus tapering. Patients were instructed to keep a daily diary of fever severity, myalgia, chills, headache, and asthenia for 27 days. The sum of the scores of individual symptoms was used to obtain a daily FLS index. The primary outcome was the FLS index area under the curve (AUC) corrected by the number of measurement days.
RESULTS
Eighty-four patients were randomized at 11 hospitals: acetaminophen (n = 28), ibuprofen (n = 28), and corticosteroids (n = 28). No differences were detected between treatments in the mean AUC of the FLS index. With limitation of the analysis to the days of IM IFNbeta-1a injection, differences favoring ibuprofen were observed in the mean FLS index (p = 0.0007).
CONCLUSIONS
No prophylactic treatment for flu-like syndrome seems to be superior to another in terms of overall well-being during the first month of IM IFNbeta-1a therapy. However, ibuprofen confers better control of symptoms immediately following IM IFNbeta-1a injection.
