Minocycline-induced drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome with persistent myocarditis

Abstract

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare serious adverse effect associated with a variety of medications. We present a case of minocycline-induced DRESS syndrome, which resulted in acute renal failure, transient thyroiditis, and transaminitis, and a persistent lymphocytic myocarditis resulting in congestive heart failure. To our knowledge, this is the third reported case of minocycline-induced myocarditis. Additionally, we report successful plasmapheresis and rituximab treatment for minocycline-induced myocarditis associated with the DRESS syndrome.
