ABSTRACT
INTRODUCTION: Dysregulated immune responses are developed in Coronavirus disease-2019 (COVID-19) and Interleukin-6 (IL-6) levels are reflecting the severity of the clinical presentation. This study aimed to analyze IL-6 serum level, Acute Respiratory Distress Syndrome (ARDS), and Acute Kidney Injury (AKI) as risk factors for mortality in children with COVID-19. METHODS: This prospective cohort study was conducted on children with COVID-19 infection confirmed by Real Time Polymerase Chain Reaction (RT-PCR) who were admitted to infection center at Dr. Wahidin Sudirohusodo Hospital from September 2021 to September 2022. Subjects were selected using the consecutive sampling method. RESULTS: A total of 2,060 COVID-19 RT-PCR tests were performed, and 1,065 children were confirmed positive. There were 291 cases that met the inclusion criteria, with 28.52 percent non-survives and 71.48% survives. The risk factors for mortality were IL-6, ARDS, AKI, Prothrombin Time / Activated Partial Thromboplastin Time (PT/aPTT), oxygen saturation, Absolut lymphocyte count (ALC), leukocytes, Length of Stay (LOS), and nutritional status (p<0.05). IL-6 levels increased in all patients (23.48-252.58 pq/ml). COVID-19 patients with AKI, ARDS, low oxygen saturation and thrombocytopenia had the highest levels of IL-6 (p 0.05). The IL-6 cut-off point was >80.97 pg/ml with 93% sensitivity and 90% specificity. Area Under Curve was 0.981 (95% CI), 0.960-1.000). A multivariate analysis showed IL-6 levels with OR 18.570 (95% CI 5.320-64.803), ARDS with Odds Ratio (OR) 10.177, (95% Confidence Interval (CI) 1.310-9.040), and AKI with OR 3.220 (95% CI 1.070-10.362). A combination of increased IL-6, ARDS, and AKI can predict a mortality probability as high as 98.3%. CONCLUSION: IL-6, ARDS, and AKI are risk factors for mortality in children with COVID-19. IL-6 level was the highest mortality risk factor.

PURPOSE: To analyze risk factors and various nutrients associated with stunting among children aged 6-60 months. METHODS: This is a case-control and cross-sectional study between 40 stunting cases and 40 controls. Data on possible risk factors associated with stunting were obtained through direct interviews and using a questionnaire. Examination of vitamin D, zinc, albumin, and ferritin levels was performed on both groups. Data were analyzed using IBM SPSS Statistics for Windows, Version 23.0 (IBM Co., Armonk, NY, USA) to determine risk factors for stunting and to assess the relationship between nutritional levels and stunting. RESULTS: The incidence of stunting was highest in children aged 12-36 months. Children with low weight and very low weight for age comprised of 55% and 22.5%, respectively, of the study participants. The highest mother's educational level was junior high school (40%). History of low birth weight (LBW) was more commonly observed in the stunting group than that in the control group (25.0% and 7.5%, respectively; p=0.034, odds ratio, 0.310 [95% confidence interval, 0.122-0.789]). Approximately 7.5% of cases had premature birth. Exclusive breast feeding was found to be not correlated with stunting. The mean zinc level in the stunting group was 34.17 ng/mL, which was different from that in the control group (50.83 ng/mL) (p=0.023). Blood ferritin, vitamin D, albumin, and calcium levels were not strongly correlated with stunting. CONCLUSION: LBW is the main risk factor contributing to stunting and is strongly associated with low zinc level.
