COVID-19 is a highly infectious disease with varied presentation as well as outcome. Inflammation plays a major role in the outcome of COVID-19 infection. This study was aimed to evaluate the role of conventional feasible inflammatory markers in predicting the outcome of COVID-19 in hospitalized adult patients.
Material: A total of 100 confirmed COVID-19 patients were included in the study. Clinical and demographic data were collected. Biochemical, hematological, and inflammatory markers were assessed in all the patients. Disease severity and primary outcome as survival and or mortality were recorded.
Observation: Hematological indices and inflammatory markers were significantly higher among the non-survivor. N/L (Neutrophil/Lymphocyte) ratio and CRP (C-reactive protein) can differentiate non-survivor from survivors with the sensitivity of 85.7%, 85.7%, and specificity of 96.8 %, 77.4% with a cut-off value of 6.44, 23.02 respectively in the receiver operator curve (ROC). N/L ratio and CRP were significantly increased among the patients with severe COVID-19 infection. Cox regression Survival analysis showed that an elevated N/L ratio and CRP were significantly associated with mortality with the Hazard ratio of 1.331 (P <0.001) and 1.014 (P <0.015) respectively.
Conclusion: The present study implicates that increased N/L ratio and CRP were significantly correlated with severity and mortality in COVID-19 patients. These conventional feasible markers can be useful in predicting the outcome of COVID-19 infection.
