Abstract
A 2-year-old boy had a severe cytomegalovirus (CMV) infection with multi-organ involvement, while on maintenance therapy for acute lymphoblastic leukemia. The patient was treated with intravenous gancyclovir, with a marked improvement in his clinical status, with the exception of a progressive deterioration of the renal function. He also developed hemolytic anemia and thrombocytopenia, suggesting a diagnosis of atypical hemolytic uremic syndrome (HUS). A percutaneous renal biopsy showed lesions consistent with HUS, but no evidence of CMV infection. The patient had a good clinical outcome with no evidence of renal sequelae. We report a rare association of CMV infection and HUS in the pediatric age-group, which suggests a possible cause-effect relationship that deserves further evaluation.
