Prognostic value of neutrophil to lymphocyte ratio and platelet to lymphocyte ratio for mortality in patients infected with SARS-CoV-2

The COVID-19 pandemic, which originated in China and spread all over the world, continues to be a significant public health crisis. Neutrophil lymphocyte ratio (NLR) platelet (PLR) are valuable parameters that can evaluated routine blood tests provide information about inflammation many diseases.
 This study aimed evaluate effect of NLR PLR on mortality.
 Methods. Our cross-sectional cohort included patients who were hospitalized due with positive polymerase chain reaction test results whose negative at time first admission hospital, but computed tomography imaging was suspicious for found repeated during their hospitalization. Prognosis hospitalization outcomes investigated discharge, hospital admission, intensive care unit (ICU) mortality data 30 days recorded relationship between these evaluated.
 Results. mean age 57.5 ± 16.7 years. Cough most common symptom present half patients. Almost one-third (27.1%) had least three symptoms presentation. Both increased levels observed significantly predict (p<0.001, p=0.001, respectively). Sensitivity specificity 65.2% 80.4% (AUC: 0.767, cut-off>5.49) 43.5% 81.9% PLR, respectively 0.622, cut-off>228.13).
 Conclusions. has concluded effective predictors infected SARS-CoV-2.
