Septicemia in acute leukemia

We have surveyed septicemic episodes occuring in individuals with acute leukemia and have found two factors favorably influencing survival, mainly granulocyte counts over 1,000 mm3 and gram-positive bacteremias. In contrast, blood cultures persistently positive for longer than 48 hours were a bad prognosticator. Significantly, patients with gram-positive bacteremia had received less antibiotics in the week prior to septicemia than had patients with gram-negative bacteremia.
