Cytomegaloviremia in children with acute lymphocytic leukemia.
Leukocyte and urine cultures were done at monthly intervals in 36 children with acute lymphocytic leukemia known to be excreting cytomegalovirus in their or saliva in order to determine the relationship of viremia to clinical cytomegalic inclusion disease. Eleven of 36 (30.5%) patients had viremia. Viremia was related to clinical disease in only three patients; two with chorioretinitis and one with a CMV monomucleosis syndrom. However, the presence of viremia did not serve as a useful means to determine active CID. Viremic patients with CID all had elevated serum levels of IgM and multiple episodes of viremia. Viremia was not related to the duration, type or number of drugs used in immunosuppression, nor to the hematologic status of leukemia. Viremic patients received more blood transfusions than noviremic patients, but the administration of blood products could not be related to the acquisition of infection. Leukopenia, neutropenia, total lymphocyte count, fourfold rise or fall in complement-fixing titer, and viruria had no consistent relationship to viremia or clinical CID.
