Abstract:
OBJECTIVE:To analyze the clinical characteristics of predictors in pediatric acute leukemia complicated with septic shock and explore the prognostic factors.
METHODS:The clinical characteristics of 70 children with acute leukemia and complicated with septic shock hospitalized in Sun Yat-sen Memorial Hospital from March 2012 to March 2021 were retrospectively analyzed. The clinical characteristics of patients in survival group and death group were analyzed and compared. Multiple logistic regression was used to test for predictors of death.
RESULTS:Among the 70 children, 41 were males and 29 were females, with a median age of 7.0 (1.0-15.0) years old. 81.4% were hospital acquired infections. The pathogens were mostly Gram-negative bacteria (50/66, 75.8%) and the clinical manifestations were cold shock. Mortality rate was 34.3% (24/70). The length of hospitalization, duration of fever and antibiotic exposure longevity before the onset of septic shock were significantly different between survival group and death group. At septic shock onset, compared with the survival group, patients in the death group were younger, had lower platelet counts and higher levels of C-reactive protein and procalcitonin, and were more likely to have acute heart failure and more mechanical ventilation (all p<0.05). The results of multivariable analysis showed that mortality was independently associated with pediatric sequential organ failure assessment score (pSOFA) (odds ratio: 1.616, 95% CI: 1.160-2.251, p=0.005) and acute heart failure (odds ratio: 18.308, 95% CI: 1.939-172.911, p=0.011). In addition, the ROC curve analysis showed that pSOFA score had AUC of 0.8551 (95% CI: 0.7607-0.9495, p<0.001) predicting PICU mortality and its best predictive value was >9.5 (sensitivity 75.0%, specificity 87.0%).
CONCLUSION:Pediatric acute leukemia complicated with septic shock is characterized as rapid deterioration and high mortality. A pSOFA score greater than 9.5 and acute heart failure are associated with poor outcomes.
