Cytomegalovirus (CMV) is a cause of enteritis associated with hematopoietic stem cell transplantation (HSCT), but the natural history is rarely studied and hence poorly understood. CMV infection at this end-organ site is notably less frequent than is pneumonitis. To evaluate the spectrum of CMV enteritis after HSCT, we reviewed the database spanning 11.5 years of 2240 University of Minnesota transplantation patients for cases of gastrointestinal CMV. We identified 46 case-patients. The incidence of CMV enteritis at 2 years following HSCT averaged 2% over the 11.5-year study interval. The median time to diagnosis of CMV enteritis after HSCT was 91 days (range, 17-527 days). The methods used in diagnosis included histopathology (58%) and virology (61%). Viremia was detected in two thirds of patients with CMV prior to the diagnosis of enteritis. Most treatment regimens included ganciclovir. The overall survival rate was 35% at 2 years following the onset of enteritis.
