Prevalence of Diabetes Mellitus and Impaired Glucose Tolerance in Patients with Covid-19

Abstract

Objective: The aim of this study is to determine the prevalence of diabetes mellitus and impaired glucose tolerance in patients with COVID-19. Study Design:Cross-sectional study Place and Duration:Conducted at department of Medicine, Khyber Teaching Hospital (KTH),Peshawer and Avicenna Teaching Hospital, Lahorefor the duration from July 2020 to December 2020. Methods: There were one hundred and fifteen patients of both genders had coronavirus disease were included in this study.Patients ranged in age from 25 to 80 years.After obtaining informed written permission, we collected detailed demographic information on all of the registered patients, including their age, gender, BMI, educational attainment and place of residence. All of the patients had their blood tested for corona disease using RT-PCR. After screening positive (fasting capillary glucose >100 mg/dl and 200 mg/dl) and each sixth consecutive negative (fasting capillary glucose <100 mg/dl) subjects, the 75-g oral glucose tolerance test was administered. The SPSS 23.0 software was used for analyzing of data. Results:Included patients had mean age 59.4±12.55 years with mean body mass index 29.12±11.76 kg/m2. There were 70 (60.9%) male patients and 45 (38.1%) females. Majority of the patients were illiterate 65 (56.5%) and 49 (42.6%) patients were from urban areas. Most common co-morbidities were hypertension, hyperlipidemia, chronic kidney disease and coronary artery disease. We found 62 (53.9%) patients had diabetes mellitus in which majority of the cases were pre-existing. Frequency of impaired glucose tolerance was found among 26 (22.6%) cases in which majority of the cases had pancreatic cancer. 28 (24.4%) cases had intubation. Overall mortality was found among 18 (15.3%) cases. Conclusion:This research found that people with diabetes and poor glucose metabolism are more likely to have severe Covid-19. A previously undiagnosed symptom of primary infection has been linked to a disorder in glucose metabolism. Pathways through which SARS-CoV-2 affects glucose metabolism must be investigated if disease aetiology is to be fully understood. Keywords:Coronavirus, DM, IGT, Co-morbidities, Mortality
