A Retrospective Study To Evaluate The Role Of Laboratory Biomarkers In Determining The Disease Severity And Early Detection Of Progression To Advanced Stage In Covid 19 Patients

ABSTRACT

Novel corona virus epidemic started in Dec 19 in Wuhan, China and soon it spread globally and became an international emergency Our objective was to study the role of hematological and biochemistry markers in assessing the disease severity and prognosis of laboratory confirmed, hospitalized Covid 19 patients. 130 patients were included in this cross- sectional retrospective study and divided into mild/moderate and severe/critical group. Correlation analysis was done for laboratory biomarkers.We found that mean age, lactate dehydrogenase (LDH), S. ferritin, urea, uric acid, D-dimer and S.creatinine of severely ill patients were significantly higher than those of patients with non-severe illness. Leucopenia and neutropenia were also associated with disease severity. Males were affected more than females with both mild and severe illness. Following parameters like S. Ferritin, LDH, TLC, neutrophil % can help in identifying the progression of disease from mild to severe and help in adopting appropriate measures in the management so that progression can possibly be prevented. Rising levels of some parameters like D.dimer, urea, uric acid and creatinine also help in explaining the prognosis of patient.
