Abstract
193 consecutive adult patients undergoing autologous bone marrow transplantation (ABMT) for lymphomas and acute leukaemias were studied retrospectively to investigate the pattern of peri-transplant septicaemia. 80% of the early peri-transplant septicaemia occurred between day 4 and day 10 after AMBT. Gram-positive septicaemia was significantly more frequent than gram-negative septicaemia. The immediate mortality rate due to septicaemia during the early post-transplant period (< 72 hours from the development of first febrile episode), whether gram-negative or gram-positive was low (1%). Most infective deaths occurred in patients undergoing ABMT for primary refractory or resistant relapsed lymphomas and as a result of pulmonary complications presumed but not always confirmed to be of infective origin.
