Gender and national characteristics of the new coronavirus infection (COVID-19) in the Trans-Baikal territory

The aim of the research. To study the gender and national characteristics of the new coronavirus infection COVID-19 among Russian and Buryat nationalityresidents of the Trans-Baikal Territory.

Materials and methods. The study involved 196 patients of Russian and Buryat nationality who were being treated in the mono-hospital of the State Clinical Hospital № 1, Chita, with a clinical picture of the new coronavirus infection COVID-19, typical changes in multispiral computed tomography of thoraxorgans, a positive SARS-CoV -2 smear by a polymerase chain reaction; or a negative smear combined with clinical data and multi-helical CAT scans of the thorax organs. Descriptive statistical methods were used for statistical data processing.

Results. In most patients of the studied groups, pneumonia on the background of coronavirus infection had a severe course and was combined with pathology of the respiratory, cardiovascular and endocrine systems. At the same time, patients of Russian nationality had a history of myocardial infarction, acute cerebral circulatory disorders and oncological diseases more often. Russian patients were more likely than Buryat patients to suffer from diabetes mellitus, Russian patients were more likely to have post-infarction cardiosclerosis compared to Buryat patients. Both men and women of Buryat nationality had a frequency of pneumonia of the 3-4 radiological stage against the background of COVID-19 exceeded this parameter of patients of Russian nationality. A positive smear for SARS-CoV-2 was more often registered in Buryat nationality. The frequency of use of GIBP in the treatment of a new coronavirus infection in patients of Russian and Buryat nationalities did not differ. In laboratory blood tests in patients of the studied groups, significant differences in the levels of neutrophils, aspartate aminotransferase and glucose were revealed.

Conclusions. The level of blood neutrophils in Buryat patients exceeded this parameter in Russian patients, which suggests a more frequent development of viral-bacterial association in Buryat patients, which may explain the subtotal and total volume of lung tissue damage during X-ray examination in patients of this group.
