Voriconazole-associated myositis

J Clin Rheumatol. 2009 Oct;15(7):350-3. doi: 10.1097/RHU.0b013e318188bea7.

Abstract

Voriconazole is a new triazole antifungal agent that is now the treatment of choice for invasive aspergillosis. Drug-induced myopathy has never previously been reported with voriconazole, although it is recognized with other triazole agents. We present a 34-year-old female African American renal transplant recipient, with a prior history of probable statin-induced myopathy, who developed severe generalized weakness with marked elevation of muscle enzymes and inflammatory changes on T2-weighted fat-suppressed STIR sequence magnetic resonance imaging (MRI) after commencing voriconazole for treatment of invasive aspergillosis. Her symptoms resolved and creatine kinase normalized upon stopping the drug.Given the increased use of triazoles in immunosuppressed and transplant recipients, it is important for rheumatology consultants to include this entity in their differential diagnosis of weakness in such patients.
