Fungal Infections Associated with Contaminated Methylprednisolone Injections — Preliminary Report

Abstract

ABSTRACT Background Fungal infections are rare complications of injections for treatment of chronic pain. In September 2012, we initiated an investigation into fungal infections associated with injections of preservative-free methylprednisolone acetate that was purchased from a single compounding pharmacy. Methods Three lots of methylprednisolone acetate were recalled by the pharmacy; examination of unopened vials later revealed fungus. Notification of all persons potentially exposed to implicated methylprednisolone acetate was conducted by federal, state, and local public health officials and by staff at clinical facilities that administered the drug. We collected clinical data on standardized case-report forms, and we tested for the pres-ence of fungi in isolates and specimens by examining cultures and performing poly-merase-chain-reaction assays and histopathological and immunohistochemical testing. Results As of October 19, 2012, more than 99% of 13,534 potentially exposed persons had been contacted. As of December 10, there were 590 reported cases of infection in 19 states, with 37 deaths (6%). As of November 26, laboratory evidence of
