ABSTRACT
Background: To date, the 2019 novel coronavirus pneumonia (COVID-19) is the greatest public medical issue in the world. World Health Organization (WHO) declared this outbreak a “public health emergency of international concern” on January 31, 2020. Therefore, it bodes well to look for a potential biomarker that could quickly and effectively distinguish serious cases early. Of the total confirmed Covid-19 patients, the severe cases often suffer from underlying diseases such as cardiovascular disease and diabetes that can accelerate the movement of 2019 novel coronavirus (SARS-CoV-2) infection. Moreover, acute respiratory distress syndrome could lead to death in some severe Covid-19 patients, and various disorders often accompany this. Biochemical findings showed representative features of acute respiratory distress syndrome and association of multiple organs. Aim: To estimate routine biochemical parameters of patients admitted to the Covid-19 ward. Method: Clinical samples from cases of Covid-19 admitted to Adesh Medical College and Hospital, Mohri, Shahbad (M), Haryana, India, during 1st, 2nd, and 3rd waves were collected and analyzed. Result: In this study, we investigated routine biochemical investigations (RBS, LFT, RFT & Serum Electrolyte) of Covid-19 patients and calculated De Ritis ratio. It was found that biochemical parameters and De Ritis ratio were worse affected than the first and second waves. Conclusion: De Ritis ratio may be a good marker for liver abnormalities and prognosis and a hospital stay of the Covid-19 patients.
