Диагноз ассоциированной с COVID-19 пневмонии выставлялся врачом-клиницистом на основании данных ПЦР-теста и актуального КТ-исследования органов грудной клетки. Всего было обследовано 195 последовательно набранных пациентов. Средний возраст обследованных составил 54 (12,1) года.</p></sec><sec><title>Результаты</title><p>Результаты. Значимо большее число пациентов с тяжелым течением коронавирусной инфекции на момент госпитализации были активными курильщиками (33 (29,73%) против 67 (79,6%); p &lt; 0,002) и имели ИМТ, соответствующий предожирению/ ожирению (42 (37,84%) против 44 (52,38%); p = 0,027). У пациентов с тяжелым течением COVID-19 в общем анализе крови отмечалось значимо большее содержание лейкоцитов (6,054 (2,813) против 7,307 (4,707); p = 0,021). Также группы достоверно отличались по содержанию микро- и макроэлементов. Выявленный в нашем исследовании дисбаланс минеральных веществ публикуется впервые, так как содержание Al, B, Li, Co, Sr и Si у пациентов с COVID-19 не изучалось.</p></sec><sec><title>Заключение</title><p>Заключение.

The diagnosis of COVID-19-associated pneumonia was made by a clinician on the basis of PCR test data and an up-to-date chest CT scan. A total of 195 consecutively recruited patients were examined.

Significantly more patients with severe coronavirus infection at the time of hospitalization were active tobacco smokers (33 (29.73%) vs 67 (79.6%); p &lt; 0.002) and had a BMI consistent with pre-obesity/obesity (42 (37.84%) vs 44 (52.38%); p = 0.027). In patients with severe COVID-19, a significantly higher content of leukocytes was noted in the complete blood count (6.054 (2.813) vs 7.307 (4.707); p = 0.021). The groups also differed significantly in the content of micro- and macroelements. The imbalance of minerals revealed in our study is published for the first time, because.
