Prognostic Role of NLR and RBS Levels in Diabetic Patients With Severe Covid-19 Disease

Abstract

Objective-This retrospective study was done to assess the role of NLR (Neutrophil to lymphocyte ratio) and RBS (RANDOM BLOOD SUGAR) levels at the time of admission as prognostic markers and correlate them with clinical outcome. Materials and methods:Atotal of 100 diabetic patients with severe COVID-19 Disease, requiring ICU admission were studied at SRN Hospital, Prayagraj. Blood samples were sent for various inammatory markers along with random blood glucose levels. Patients were divided as survivors and non- survivors. Results: The mean NLR was higher in the group of patients who did not survive (11.35±8.09) than in the patients who survived (7.79±5.27). Mean RBS (in mg/dL) in the survivor group and the non-survivor group at the time of admission was 232.19±133.75 and 333.41±130.81 respectively. The NLR, RBS, CRP cutoff were identied as >7.247, >254.6 mg/dL,>12.86 mg/Lrespectively to predict mortality using the ROC curve (p value <0.05). Conclusion:NLR and RBS at the time of admission can be easily used as surrogate markers for predictors of mortality. Screening and intensive glucose control is strictly recommended for all diabetic patients.
