Objective: The purpose of this study was to analyze the neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), platelet to lymphocyte ratio (PLR), mean platelet volume (MPV) as a predictor for mortality in children with sepsis.
Design: This was a prospective cohort study.
Setting: In Pediatric Intensive Care Unit (PICU), Emergency Room, and pediatric ward at Dr. Soetomo General Hospital, Surabaya on March 1, 2020 to August 2020.
Patients and participants: A total of 80 children consisted of 40 septic and 40 non-septic patients were included.
Measurement and results: The leukocyte count in septic patients was not significantly higher than in non-septic patients with a p value>0.05. The number of neutrophils (12.99±7.35×103/mm3 versus 9.12±6.67×103/mm3) had a relevant and significantly higher increase in septic patients (p=0.014). The NLR value (8.99±6.73 versus 4.80±5.30; p=0.001) was higher in septic patients. The cut-off of NLR as a diagnostic marker for sepsis was 3.52 with sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and odds ratio (OR) of 82.50%, 47.50%, 61.11%, 73.08%, and 4.26 (p=0.004), respectively. The MLR, PLR, and MPV did not differ significantly between septic and non-septic patients. NLR values (11.61±7.39 versus 5.77±4.05; p=0.014) between survive and dead septic patients. The NLR cut–off 8.98 has sensitivity, specificity, PPV, NPV, and OR of 77.78%, 54.55%, 58.3%, 75%, and 4.20 (p=0.038), respectively, as a predictor for mortality. Patient with NLR more than 8.98 has a risk for mortality 4.20 times higher than those with a low or equal NLR value.
Conclusion: NLR can be used as a predictor of mortality in children with sepsis.
