Severe raltegravir-associated rhabdomyolysis: a case report and review of the literature.

Raltegravir (RAL), an HIV integrase inhibitor, may uncommonly induce an increase of serum creatine kinase (CK) both in naïve and antiretroviral (ARV)-experienced HIV-positive patients. We report the case of severe rhabdomyolysis requiring hospitalization in an ARV-experienced HIV/hepatitis C co-infected patient treated with a RAL-containing drug regimen. Factors favouring a severe clinical occurrence of RAL-induced rhabdomyolysis from cases reported in literature are described.
