Tóm tắt

We aimed to analyze infections in children undergoing hematopoietic stem cell transplantation (HSCT) until engraftment. The spectrum and risk factors associated will help plan interventions to reduce mortality. We performed a retrospective analysis on the infections, associated risk factors, and mortality until engraftment in children up to 18 years of age undergoing HSCT from January 2017 to August 2020. A total of 399 children were included, with a male: female ratio of 1.9:1, with matched related donor HSCT in 36.6%, a matched unrelated donor in 18.3%, and haploidentical HSCT in 38.1% of children. Culture positive bacteremia was documented in 22.1% transplants with gram-negative bacteria (GNB) isolated in 71/88 (80%). Among the GNB, the predominant organism was Klebsiella pneumonia in 38 (53%), E.coli in 16 (22%), Pseudomonas in 9 (12%). Carbapenem resistance was documented in 24/71 (33%). The incidence of possible, probable, and proven fungal infections in the cohort was 63 (15%), 28 (7%), and 6 (1.5%), respectively. Mortality up to engraftment due to sepsis in our cohort is 3.3% (n = 13). There was a significant association between mortality and a perianal focus (30.8%, p value 0.029) and the presence of carbapenem resistance (38%, p value 0.002). Mortality among those who developed proven fungal infections was significantly higher than those with bacteremia (p value 0.004). Our study has identified fungal sepsis and carbapenem-resistant GNB sepsis as high-risk groups for mortality. Risk directed interventions in these groups would help ensure survival and optimal outcomes.
