Could serum thrombocyte/lymphocyte (TLR), neutrophil/lymphocyte (NLR) and neutro-phil/albumin (NAR) ratios be indicators of hospitalization and mortality in COVID-19?
Background and Objectives: Neutrophil / lymphocyte (NLR) and thrombocyte / lymphocyte ratios (TLR) are also a guid- ing factors in the prognosticevaluation of infectious diseases. Another parameter to determine inflammation and prognosis is albumin. This study was aimed to determine whether TLR,NLR and neutrophil / albumin ratios (NAR) are effective in predicting the severity and course of Corona Virus Disease-2019 (COVID-19).
Materials and Methods: In this retrospective and cross-sectional study, a total of 1597 patients who were admitted to our hospital between 15.03.2020- 1.06.2020, diagnosed with COVID-19 were evaluated.
Results: In the estimation of the decision for hospitalization, TLR, NLR and NAR AUROC values were 0.596, 0.634, 0.602 for cutoff values 123.7, 2.3 and 839.5, respectively. In predicting mortality, TLR, NLR and NAR AURO sample size can be specified C values were 0.674, 0.821, 0.787 for cutoff values 168.1, 5.2 and 1303.4, respectively (p 0.001 for all).
Conclusion: In our study, it was determined that TLR, NLR and NAR are independent predictors in making the decision of hospitalization and in determining the prognosis in patients who are decided to be hospitalized.
