ABSTRACT
Objective:
To investigate the clinical features of septic shock in children with hematological malignancies compared with those without malignant tumor in the pediatric intensive care unit (PICU).Methods:
This retrospective study enrolled children with septic shock at the PICU of Capital Institute of Pediatrics' Children's Hospital from June 2015 to July 2022. According to the presence of hematological malignancies, patients were divided into the hematological malignancies group and without malignant tumor group. Clinical data were compared between the two groups, and logistic regression analysis was used to identify related factors for mortality.Results:
A total of 164 children (97 males and 67 females) with a median age of 3.6 (interquartile range 0.8, 7.8) years were enrolled, including 75 (45.7%) patients with hematological malignancies and 89 (54.3%) patients without malignant tumors. Patients in the hematological malignancies group were older [6.0(3.6, 9.4) years vs 1.2 (0.4, 4.3) years, P<0.001] and more experienced hospital-acquired infections [48.0%(36/75) vs 21.3%(19/89),P=0.001], compared with patients without malignant tumors. Surgical emergencies were more frequent in patients without malignant tumors (32.6% vs 14.7%, P=0.013). Patients with hematological malignancies mainly had blood stream infections (58.7%), with Gram-negative bacilli (46.7%), meanwhile, patients without malignant tumors more experienced Gram-positive cocci infections (22.5%) of the respiratory system (40.4%) or digestive system (28.1%). There were significant differences regarding the infection sites (P<0.001) and pathogens (P=0.001). The types of antibacterial agents (P<0.001) and the frequency of noradrenaline (P=0.013) used in patients with hematological malignancies were significantly higher than those without malignant tumors. Patients with hematological malignancies had a higher incidence of multiple organ dysfunction (MODS) [100.0%(75/75) vs 80.9%(72/89), P<0.001] and higher 28-day mortality [34.8%(23/66) vs 19.0%(15/79),P=0.048]. Multivariate logistic regression analysis showed that Pediatric Critical Illness Score (PCIS) was an independent factor for death (odds ratio, OR=1.387, 95%CI 1.161-1.657, P<0.001) in patients with hematological malignancies, and PCIS (OR=1.419, 95%CI 1.140-1.767, P=0.002) and the 6-hour lactate clearance rate (OR=65.857, 95%CI 2.953-1 468.638, P=0.008) were independent factors for death in patients without malignant tumors.Conclusions:
Children with hematological malignancies were older, more frequently experienced bloodstream infections, and had a higher incidence of MODS and higher 28-day mortality. PCIS is related to poor prognosis of septic shock in children.
