Purpose. Description and illustration of the most common alternative causes of shortness of breath, cough, and acute chest pain in pandemic COVID-19 conditions. Material and methods. Authors evaluated results of the retrospective single-center study and instrumental data of 67 patients with complaints of sudden chest pain, cough and shortness of breath. For patients admitted to the hospital between March, 27 and June, 30, 2020, the first stage of diagnosis was made with the performed multispiral computed tomography (MSCT) of the chest, confirming the presence of pulmonary manifestations of COVID-19. The study did not include patients with pneumothorax identified at the pre - and hospital stages. We describe early radiographic changes in the chest organs, main vessels, and coronary bed in patients with CT-confirmed COVID-19 admitted to O.M. Filatov Municipal Clinical Hospital No. 15, Moscow for sudden chest pain, cough, and shortness of breath. Results. In CT of the chest organs, combinations of COVID-19 and pulmonary artery thromboembolism, central/peripheral lung cancer, and acute aortic syndrome manifestations were most common. Combinations of radiation techniques in pandemic settings are COVID-19 required by patients with the acute coronary syndrome. However, it will be possible to analyze all cases of a combination of acute chest pain and sudden shortness of breath in patients with COVID-19 only after processing an extensive array of data. Conclusion. In pandemic conditions, COVID-19 performing standard imaging methods should be not lost about the most frequent causes of chest pain and sudden shortness of breath, complementing native MSCT with contrasting enhancement in suspected pathology of the main arteries, and small circulation in high-risk patients.

Numerous studies showed that diabetes mellitus (DM) increases the risk of death from COVID-19 by five times. It is generally accepted that the high lethality of COVID-19 against the background of DM is due to the main complications of this disease: micro-and macroangiopathies, as well as heart and kidney failure. In addition, it was shown that acute respiratory viral infection increases the production of interferon gamma, increases muscle resistance to insulin, and modulates the activity of effector CD8+ T cells. The ability of CD8+ T cells to recognize SARS-CoV-2-infected cells depends not only on humoral factors but also on individual genetic characteristics, including the individual set of major histocompatibility complex class I (MHC-I) molecules. In this study, the relationship of the MHC-I genotype of patients with DM aged less than 60 years with the outcome of COVID-19 was studied using a sample of 222 patients. It was shown that lethal outcomes of COVID-19 in patients with DM are associated with the low affinity of the interaction of an individual set of MHC-I molecules with SARS-CoV-2 peptides.
