Why do people with diabetes have poor results in the treatment of COVID-19? (review and practical recommenda-tions)

B.M. Mankovsky, O.A. Halushko


Background. On March 11, 2020, the World Health Organization declared coronavirus disease 2019 (COVID-19) a pandemic. As of May 15, 2020, a total of 4,539,401 cases of COVID-19 and 303,551 deaths had been reported worldwide. In Ukraine, coronavirus infection COVID-19 was first diagnosed on March 3, 2020 in Chernivtsi, and on March 13 the first fatal case due to coronavirus infection was recorded. As of May 15, 2020, there were 17,330 cases of the disease in Ukraine, of which 476 were fatal (mortality - 2.7 %), 4473 patients recovered (25.8 % of those who fell ill). In Ukraine, as well as in the world as a whole, during the spread of severe acute respiratory syndrome coronavirus-2, data are constantly published that certain groups of patients are at higher risk of COVID-19. These include patients with hypertension, heart disease and diabetes mellitus (DM). The purpose was to analyze the causes of the negative impact of diabetes on the course of COVID-19 and to formulate recommendations for prevention and treatment for patients with DM and their doctors. Material and methods. To solve this problem, a search was carried out for publications using the search engines PubMed and Google Scholar. Search terms were used: COVID-19, diabetes mellitus, hyperglycemia, hypoglycemia, complications. As a result of the search for the indicated terms, a total of 267 publications were identified, published from the beginning of the epidemic in December 2019 to May 14, 2020. Results. The main risk factors for the development and severe course of ­COVID-19 are considered to be old age, arterial hypertension, diabetes mellitus (DM), cardiovascular and cerebrovascular diseases. Based on the analysis of specialized publications in the search engines PubMed and Google Scholar, the reasons for the negative impact of DM on the course and results of patients with COVID-19 treatment are established, recommendations are made for the prevention and treatment of patients in the case of a combination of COVID-19 disease and concomitant diabetes. Conclusions. We consider it appropriate to formulate recommendations for the management of patients with DM in the context of the COVID 19 pandemic created on the basis of the analysis of publications and modern international guidelines.
