eplerenone and Cytomegalovirus-Infections

A 50-year-old man was referred to our hospital for colitis with abdominal pain and diarrhea that had persisted for more than 8 months. 9 months earlier, he had been treated for fulminant eosinophilic myocarditis. During steroid therapy, ulceration appeared in the esophagus, stomach and large intestine. The biopsy results showed cytomegalovirus (CMV) inclusion bodies, and the patient was diagnosed with CMV gastrocolitis and treated with ganciclovir. Colonoscopy 7 months earlier revealed ischemia-like segmental colitis 10 cm in length in the hepatic flexure without evidence of CMV infection. Colonoscopy after 1 month and 3 months showed no improvement. We suspected drug-induced focal ischemic colitis, and discontinued eplerenone. Colonoscopy 2 months after withdrawal of eplerenone showed improvement in colitis, and colonoscopy 8 months later showed ulcer healing. Venous disorders are cautioned as a known side effect of eplerenone, but this is the first report of venous stasis colitis thought to be caused by eplerenone.
