Clinical and Biochemical Profile of COVID-19 Patients Admitted in a Tertiary Care Hospital of Kolkata

Introduction: The disease caused by Coronavirus (COVID-19), is now pandemic all over the world including India. There are different manifestations of the disease from asymptomatic and mild to severe form. Clinical severity varies from country to country. This study was conducted to document different clinical and biochemical profiles in this Tertiary Care Hospital of Kolkata. Aim: The study was done to observe and to compare the clinical and biochemical profile in asymptomatic to mild and moderate to severe symptomatic patients. Materials and Methods: This was an observational study conducted in Medical College, Kolkata, West Bengal, India. The study was conducted from June 2019 to mid-August 2019. Total 573 Real Time Polymerase Chain Reaction (RT PCR) positive COVID patients were included in this study. All patients were examined and investigated with blood parameters. Patients were divided into two groups (Group A-asymptomatic and mild symptoms and Group B moderate and severe symptoms) clinically. Statistical calculators like Statistical Package for Social Sciences (SPSS) and Soccalculator were used and different biochemical parameters were analysed using Chi-square, unpaired T-test to find out significance among these two groups. Results: Among 573 patients, 222 were in group A and 351 were in group B. Fever was the most common presenting feature (69.6%) followed by dry cough and shortness of breath. Other features were malaise/fatigability, diarrhoea and anosmia. Among the co-morbidities hypertension and diabetes were significantly different between the two groups. Among the biochemical parameters Neutrophil-Lymphocyte Ratio (NLR), C-Reactive Protein (CPR), D-dimer, Prothrombin time, Serum Glutamic Oxaloacetic Transaminase (SGOT), Serum Glutamic Pyruvic Transaminase (SGPT) were significantly different between the two groups. Conclusion: In a tertiary care hospital of Kolkata, fever is the most common presentation followed by dry cough and fatigability in COVID patients. Diabetes and hypertension are the common co morbidities. CRP, NLR, D-dimer, prothrombin time, SGOT and SGPT should be monitored to differentiate between mild and severe cases.
