The Relationship between Diabetes Mellitus and The Prognosis of COVID-19

Background: Coronavirus disease 2019 (COVID-19) is firstly reported in Wuhan, China. Then, it was quickly spread and becomes an epidemic. It is due to infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is highly transmissible with a great risk of mortality. Patients with diabetes mellitus (DM) are more prone to infectious agents like SARS-COV-2. Aim: The aim of the study is to evaluate the relationship between DM and COVID-19 infection regarding to its severity, mortality, rate of admission, complications, and prognosis.Patients and methods: A cross sectional study was performed between April 2021 and September 2021 and included 75 patients divided into two groups: Group A (COVID-19 patients with diabetes: n= 25), Group B (COVID-19 patients who developed diabetes: n= 25) and Group C (COVID-19 patients without diabetes: n= 25). Demographics, clinical, laboratory, radiologic, management, complications, and clinical outcomes data were collected and compared between the groups.Results: Patients with diabetes had a higher complication rate, like respiratory failure, acute cardiac injury. The respiratory failure did not significantly different between groups (it was 20%, 28% and 12% in groups A, B and C, respectively, P = .368). However, acute cardiac injury had been significantly increased in groups A than group B and in A and B than group C. (It was 44%, 20% and 8%, in groups A, B and C, respectively, P= 0.01). The mortality rate was also significantly higher among the A and B than C group (56%, 40% vs 8%, P=0.001).Conclusion: Diabetes is an independent risk factor for the prognosis of COVID-19. Diabetic patients should be intensely monitored during treatment, especially those who require insulin therapy.Background: Coronavirus disease 2019 COVID-19 was first reported in Wuhan, China.

Diabetic patients should be closely monitored during treatment, especially those requiring insulin therapy.
