Background : Sepsis is a life-threatening condition that drives physiological changes interaction between immune, autonomic, and neuroendocrine systems in response to infection. The two main neuroendocrine changes during sepsis are hypothalamic-pituitary-adrenal and hypothalamic-pituitary-thyroid axis malfunction. This study used factor analysis on constructing factors including neuroendocrine profile affecting outcome in pediatric sepsis. Material : This is a cohort study of 30 consecutively enrolled children with sepsis admitted to Pediatric Intensive Care Unit in Dr. Kariadi Hospital in 2012. A total of 13 clinical characteristics of the patient were recorded including age, gender, nutritional status, blood culture, diagnosis (surgical/nonsurgical), serum cortisol level, serum thyroid profile (T3, T4, and TSH), PIM (Pediatric Index of Mortality), and PELOD (Pediatric Logistic Organ Dysfunction) score (assessed subsequently on day-1, 3, and 6). Variables were analyzed using factor analysis followed by linear regression model. Results : Out of 30 children, 8 (27%) children did not survive. Factor analysis was used to construct factors affecting outcome in pediatric sepsis. Three factors were extracted with an eigenvalue of > 1. Factor 1 comprised of PIM (0.600), Cortisol level (0.857), PELOD day-3 (0.913), and PELOD day-6 (0.927) with variance of 46.69%; Factor 2 comprised of Diagnosis (0.841) with variance of 19.06%; and Factor 3 comprised of TSH level (0.844) with variance of 14.60%. Cumulative % of Factor 1 and Factor 2 was 65.76%. Together, all three factors account for 80.36% of the variability in the 13 clinical variables. Linear regression analysis demonstrated strong correlation between the three factors and the outcome (r = 0.801), and significantly explained 64.2% of the variance on outcome (P <0.001). Conclusions : Three factors were constructed using factor analysis and assigned as the factors affecting outcome in pediatric sepsis. Factor 1 comprised of PIM, Cortisol level, PELOD day-3, and PELOD day-6; Factor 2 comprised of Diagnosis; and Factor 3 comprised of TSH level. Comprehensive management regarding to these three factors may improve outcome in pediatric sepsis.
