[Development of the risk of infection in the child with leukemia].
Infection is the leading cause of illness and death in children with leukemia. The risk of infection may change over time as regimens of therapy are modified. A review of the hospital charts of 166 infants in whom leukemia had been diagnosed between 1976 and 1980 revealed an increased number of deep fungal infections (20 v. 3) during this period in comparison with the number between 1969 and 1976 in 164 patients treated at the same hospital whose leukemia was diagnosed between 1969 and 1975. The 20 severe fungal infections between 1976 and 1980 were characterized by difficulty of diagnosis (a definite diagnosis having been made three times out of four only at autopsy), an important role of Candida but also of Aspergillus (the latter having been isolated almost as often as the former) and a grave prognosis (the mortality being very high [75%] and much above that for gram-positive septicemia [6%] and that for gram-negative septicemia [31%]). This increase in frequency of fungal infections was concurrent with the introduction of phase-1 chemotherapy, which was often responsible for prolonged neutropenia. To reduce the risk of infection in children with leukemia it appears to be essential to improve diagnostic methods and approaches to therapy.
