BACKGROUND: Sepsis in children with cardiovascular involvement can increase mortality. Recently, many studies have been conducted to investigate troponin as an early marker of myocardial dysfunction, associated with pediatric sepsis score. Pediatric Logistic Organ Dysfunction 2 (PELOD-2) score is recent scoring to assess organ dysfunction in sepsis children. AIM: To determine the correlation between troponin T, troponin I with PELOD-2 score in sepsis as a predictive factor of mortality. METHODS: A prospective cohort study was conducted on sepsis children in PICU Haji Adam Malik General Hospital, Medan. Assessment of PELOD-2 score, serum troponin T, and troponin I levels performed on the first day and 48 hours after sepsis was diagnosed. Patients were observed until moved to the ward or died. RESULTS: A group of 41 subjects were recruited in this study. Troponin T level at 24 hours did not correlate with PELOD-2 scores. Troponin T level at 48 hours was positively correlated with PELOD-2 score (r = 0.771, p < 0.001) and had a significant association with the mortality rate (p < 0.001). Troponin T at 48 hours could be used as a predictive factor of mortality (AUC 86.4%, p < 0.001) with a cut-off point of 40.3 ng/mL (76% sensitivity, 75% specificity, RR 2.48). Troponin I levels at 24 and 48 hours also had strong correlation with PELOD-2 score (r = 0.326, p = 0.037; r = 0.691, p < 0.001) and could be used as a predictor of mortality in pediatric patients with sepsis (AUC 74.8%, p 0.008; AUC 92.6%, p < 0.001). The cut-off point of troponin I at 24 hours was 0.075 ng/mL (68% sensitivity, 68.8% specificity, RR 1.84) and at 48 hours was 0.125 ng/mL (80% sensitivity, 81.3% specificity, RR 3.13). CONCLUSION: Serum troponin T and troponin I levels at 48 hours have positive correlation with PELOD-2 score as a predictive factor of mortality in pediatric patients with sepsis.

BACKGROUND: Early detection and treatment of sepsis can prevent septic shock and reduce mortality rate. Troponin can become a prognostic factor in sepsis. However, not all health facilities are equipped to assess troponin levels. Vasoactive-inotropic score (VIS) is a simpler and more accessible method to describe hemodynamic status. The aim of this study was to assess the suitability of VIS score as early prognosis and mortality predictor of sepsisMETHODS: A retrospective study was conducted to determine the correlation between VIS and troponin levels for sepsis cases in Pediatric Intensive Care Unity (PICU) Haji Adam Malik Hospital, Medan from January 2018 to December 2019. VIS score at 48 hours, maximum VIS score, pediatric logistic organ dysfunction-2 (PELOD-2) score, cardiac troponin levels at 48 hours were taken from medical records.RESULTS: There were 54 samples analyzed. VIS scores were positively correlated (p<0.001) to troponin T and troponin I levels at 48 hours (r=0.670 and r=0.606, respectively). VIS at 48 hours and maximum VIS were related to mortality (p=0.001 and p<0.001, respectively). VIS score at 48 hours could be used as a predictive factor for mortality (area under the curve (AUC): 79.7%, p<0.001) with a cut-off point at 11 (74.4% sensitivity and 80% specificity). High VIS at 48 hours indicated poor outcomes of sepsis in children with odd ratio (OR) value: 1.99 (95% confidence interval (CI): 1.25-3.19).CONCLUSION: Vasoactive-inotropic score was suitable as an alternative to cardiac troponin T and troponin I levels at 48 hours to early detect myocardial dysfunctions and mortality in children.KEYWORDS: troponin, vasoactive-inotropic score, sepsis, children, mortality
