Rotavirus infection as cause of tacrolimus elevation in solid‐organ‐transplanted children

Abstract

Rotavirus (RV) is the most common cause of diarrheal illness in children. We report three solid-organ-transplanted patients in whom RV infection caused increased trough levels of the immunosuppressive macrolide tacrolimus (TAC) by mechanisms that are still under investigation. The virus was detected for longer in the feces of these patients than in infants not receiving immunosuppressive therapy. In association with short-term monitoring of blood trough levels of TAC, the dosage should be reduced early if symptoms of an acute gastroenteritis are present.
