Abstract
The occurrence of bacterial infections (B.I.) among 181 children with Hodgkin's disease (121 with splenectomy, 60 without splenectomy) was analyzed. Twenty-seven B.I. occurred among 22 children and included 15 episodes of bacteremia-meningitis in 14 children. B.I. occurred in all age groups, but bacteremia-meningitis occurred most commonly in splenectomized children 10 years of age or less. The frequency of B.I. in splenectomized children receiving radiotherapy was 1.4%, compared to 18.3% among those receiving chemotherapy (p < 0.05). the frequency of B.I. among non-splenectomized children receiving radiotherapy was 2.8%, compared to 23.1% among those receiving chemotherapy (p < 0.05). There was no difference in the probability of B.I. as a function of splenectomy for the corresponding groups, although all cases of streptococcus pneumoniae and hemophilus influenzae bacteremia-meningitis in splenectomized children. Overwhelming postsplenectomy bacteremia infection not related to active disease or treatment occurred in 3/121 (2.5%) children, accounting for only one fatality (0.8%).
