INTRODUCTION: Sepsis is a significant cause of morbidity and mortality worldwide. Current clinical practice, however, lacks reliable diagnostic indicators for it and its prognosis.
AIM: The present study aimed to investigate the efficacy of delta neutrophil index (DNI), which reflects the proportion of circulating immature granulocytes, in predicting infections and sepsis.
MATERIALS AND METHODS: A prospective non-interventional single-center clinical follow-up study was performed in a Bulgarian ICU between January 1, 2017 and May 31, 2018. We analyzed adult patients: 45 patients met the sepsis criteria, as defined in SEPSIS-3, whereas 37 were infected patients fulfilling no criteria of sepsis. Logistic regression and Roc-curve analysis were used to evaluate the severity and prognostic value of DNI as a prediction marker in critically ill septic patients.
RESULTS: The results have shown that at DNI values of 1.4 there is 73% sensitivity and 87% specificity (AUC 0.764, 95% CI 0.650-0.878, p=0.0001) to assume the presence of sepsis. Additionally, DNI was significantly associated with the severity of the condition of patients, the organ dysfunction and the IL-8 marker.
CONCLUSIONS: DNI may serve as a useful marker for early diagnosis of sepsis and could support decision making process regarding its treatment at an early stage of a disease development.
