Elevated Delta Neutrophil Index (DNI) as a Predictor of Systemic Inflammatory Response Syndrome (SIRS) In Patients with Generalized Peritonitis at Prof Dr. I.G.N.G. Ngoerah Hospital, Denpasar

Abstract

Background: Generalized peritonitis is an emergency case in the field of surgery. Which includes an inflammatory process in the peritoneum. Systemic inflammatory response syndrome (SIRS) is a defense response to a stressor. Delta Neutrophil Index (DNI) is a parameter that reflects the ratio of infection and inflammation. This study examines the role of DNI as a predictor of SIRS in generalized peritonitis patients at Prof. Dr. IGNG Ngoerah General Hospital. Method: Cross-sectional analytic observational research. Data collection was from July 2022 to October 2022. Patients diagnosed with generalized peritonitis were taken for blood samples. The DNI examination was carried out at the Surya Husadha Hospital Laboratory. Samples were excluded if they suffered from immunodeficiency diseases, autoimmune diseases and refused to participate. The DNI value is determined by the cut-off point on the ROC curve. Bivariate analysis using Chi square test and multivariate analysis using logistic regression test. The p value <0.05 indicates a significant result. Result: This study involved 55 respondents with 41 positive SIRS respondents and 14 negative SIRS respondents. ROC curve analysis showed the DNI value with a cut-off point of 8.9 (sensitivity 85.4% and specificity 85.7%). Bivariate analysis of the DNI 8.9 with the incidence of SIRS obtained RR 3 (p = 0.000; 95% C1 1.11- 6.90). Multivariate analysis of DNI values with the incidence of SIRS showed a significant relationship (p = 0.000). Conclusion: DNI value of 8.9 is an excellent predictor of SIRS in patients with generalized peritonitis.
