Causes of mortality in children with acute lymphocytic leukemia.

Fifty five deaths between January, 1982 to September, 1989 in children with acute lymphoblastic leukemia (ALL) were evaluated to determine the cause of mortality. Fifty cases died during remission. Infection alone was responsible for death in 26 of 55 (47.3%) cases while hemorrhage was seen in 7 (12.7%) children. Infection and hemorrhage together were responsible in another 13 cases. Gastrointestinal tract and pulmonary system were the major sites of bleeding. Infections either alone or in combination with other factors were responsible for death in 42 of 55 (76.5%) of children. Septicemia (n = 11), gastrointestinal (n = 15) and pulmonary infections (n = 10) and meningitis in 2 cases were the major sites of infections. Pseudomonas and Klebsiella in 6 cases each accounted for 54.5% of isolates.
