Beneficial effect of hepatitis in leukemic reticuloendotheliosis

Abstract
• A patient with leukemic reticuloendotheliosis had splenomegaly, neutropenia, and a severe underproduction anemia. During a three-year period, the hematocrit was never in the normal range, and periodic transfusions were required. However, after an episode of hepatitis that was positive for B surface antigen, the spleen became smaller, the number of neutrophils increased, the transfusion requirement disappeared, and the hematocrit rose to normal. Several mechanisms for this observation are proposed. (Arch Intern Med1981;141:1080-1081)
