The objectives were to compare infections during different intensities of therapy in children with acute myeloid leukemia (AML). Subjects were children enrolled on CCG 2891 with AML. In Phase 1 (induction), patients were randomized to intensive or standard timing. In Phase 2 (consolidation), those with a family donor were allocated allogeneic stem cell transplantation (SCT); remainder were randomized to autologous SCT or chemotherapy. This report compares infections between different treatments on an intent-to-treat basis. During Phase 1, intensive timing was associated with more bacterial (57.7% vs. 39.4%, P<0.001), fungal (27.4% vs. 9.9%, P<.001) and viral (14.0% vs. 3.9%, P<.001) infections compared to standard timing. During Phase 2, chemotherapy was associated with more bacterial (56.5% vs. 40.1%, P=.005), but similar fungal (9.5% vs. 6.1%, P=1.000) and viral (4.2% vs. 12.9%, P=.728) infections compared with allogeneic SCT. No differences between chemotherapy and autologous SCT infections were seen. Fatal infections were more common during intensive compared with standard timing induction (5.5% vs. 0.9%; P=.004). Infectious deaths were similar between chemotherapy, autologous SCT and allogeneic SCT. Prevalence of infection varies depending on the intensity and type of treatment. This information sheds insight into the mechanisms behind susceptibility and outcome of infections in pediatric AML.
