Diabetes Mellitus and Hypertension Increase Risk of Death in Novel Corona Virus Patients Irrespective of Age: a Prospective Observational Study of Co-morbidities and COVID-19 from India

Abstract

Elderly people and people with co-morbidities have emerged as the most vulnerable group at risk of developing complications and succumbing to novel coronavirus (COVID-19) infection. We recorded the baseline demographic profile, baseline clinical and laboratory parameters, and prevalence of various co-morbidities and their effect on the prognosis of COVID-19 cases. We conducted a prospective observational study and analyzed baseline clinical and laboratory parameters and co-morbidities and their effect on severity and mortality in 710 COVID-19 cases. Seven hundred ten patients with laboratory-confirmed COVID-19 were recruited from the 28th of March to the 31st of August 2020. The mean age was 48.4 ± 16.4years. A total of 530 (74.6%) patients were male. Overall, the mean length of hospital stay was 12.7 days. In total, 645 patients(90.8%) were mild to moderate cases and did not require initial ICU care. Sixty-five (9.2%) cases required initial intensive care unit care. Fifty (7%) admitted patients succumbed to the illness. Diabetes mellitus and hypertension increased the risk of death in COVID-19 patients irrespective of age. Increasing age and co-morbidities adversely affect the prognosis of patients of COVID-19. Diabetes mellitus and hypertension increase the risk of death in COVID-19 patients and negate the incremental effect of age on death in these patients.
