Abstract

We retrospectively evaluated the incidence and time from transplantation of bloodstream infections occurring in children receiving bone marrow transplant (BMT) at G Gaslini Children's Hospital between September 1984 and December 1997. During this period the incidence was 35% after allogeneic and 26% after autologous BMT (P = 0.08). Among these episodes, 38% after allogeneic BMT and 90% after autologous BMT were detected in the presence of neutropenia within the first 30 days from reinfusion (P <0.001). Incidence of catheter-related bloodstream infections was 40% after allogeneic and 8% after autologous BMT (P <0.001). Bloodstream infections in the absence of neutropenia were 55% after allogeneic BMT vs 10% after autologous BMT (P <0.001) and occurred later after reinfusion (mean 199 vs 41 days, P <0.001). Among the episodes occurring after allogeneic BMT and in the absence of neutropenia, 61% were related to the presence of a central venous catheter, 15% were related to the presence of GVHD, but 23% were not associated with any of major risk factors for infection. Finally, 38% of episodes following allogeneic BMT were detected after day 100 vs 1% after autologous BMT. We concluded that patients receiving allogeneic BMT experience a high incidence of bloodstream infections in the absence of neutropenia and that a significant proportion of these episodes is not clearly associated with well known risk factors such as GVHD or central venous catheters. Moreover, many episodes develop a long time after the transplantation procedure. Therefore, any febrile episode following allogeneic BMT even late and/or in the absence of neutropenia should be intensively managed.
