В 5-20 % случаях новая коронавирусная инфекция (COVID-19) вызывает двустороннюю пневмонию, которая может требовать госпитализации. Согласно данным литературы, среди госпитализированных пациентов с COVID-19 отмечается высокая частота гипокалиемии.</p><p>Цель исследования — оценить частоту гипокалиемии среди госпитализированных пациентов по поводу пневмонии, вызванной COVID-19, и оценить ее взаимосвязь с лабораторно-инструментальными па-раметрами, которые характеризуют тяжесть заболевания.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В поперечное когортное исследование включили 43 госпитализированных пациента с верифицированным диагнозом пневмонии, вызванной COVID-19. Определяли уровень калия венозной крови, оценивали различия в уровнях острофазовых показателей, сатурации крови O2 и степени поражения легочной ткани между группами пациентов с гипокалиемией и нормальным уровнем калия.</p></sec><sec><title>Результаты</title><p>Результаты. Уровень калия менее 3,5 ммоль/л выявили у 16 из 43 пациентов (37,2 %), медиана калия у пациентов с гипокалиемией — 2,9 (2,7-3,3) ммоль/л. Пациенты с гипокалиемией характеризовались более низкой сатурацией крови O2 на фоне дыхания атмосферным воздухом и большим процентом поражения легочной ткани по данным компьютерной томографии на момент поступления в стационар: 91 (89-95) против 96 (93-98)% (р = 0,001) и 64 (60-70) против 48 (36-64)% (р = 0,019) соответственно. В группе гипокалиемии отмечались более высокие уровни С-реактивного белка и лактатдегидрогеназы, различий по уровню ферритина не выявлено.</p></sec><sec><title>Выводы</title><p>Выводы. Полученные данные свидетельствуют о высокой частоте гипокалиемии у госпитализированных пациентов с пневмонией, вызванной COVID-19. У обследованных пациентов гипокалиемия была ассоциирована с большим процентом поражения легочной ткани и более высоким уровнем острофазовых показателей.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. In 5-20 % cases, a new coronavirus infection (COVID-19) can cause pneumonia and require hospitalization. There is a high incidence of hypokalemia among hospitalized patients with COVID-19. Objective. To assess the frequency of hypokalemia among hospitalized patients with pneumonia caused by COVID-19 and its relationship with the severity of the disease.</p></sec><sec><title>Design and methods</title><p>Design and methods. A cohort study included 43 patients with verified pneumonia caused by COVID-19. The level of potassium in venous blood was measured upon admission to the hospital. Differences in the levels of acute phase proteins, oxygen saturation, and the level of lung damage were compared between patients with and without hypokalemia.</p></sec><sec><title>Results</title><p>Results. The potassium level below 3,5 mmol/L was detected in 16 out of 43 patients (37,2 %), the median of potassium level in patients with hypokalemia was 2,9 (2,7-3,3) mmol/L. Patients with hypokalemia had a significantly lower oxygen saturation and higher percentage of lung tissue damage according to computed tomography: 91 (89-95) vs 96 (93-98)% (p = 0,001) and 64 (60-70) vs 48 (36-64)% (p = 0,019), respectively. Significantly higher levels of C-reactive protein and lactate dehydrogenase were observed in patients with hypokalemia.</p></sec><sec><title>Conclusions</title><p>Conclusions. Our results showed a high incidence of hypokalemia in hospitalized patients with pneumonia caused by COVID-19. Hypokalemia was positively associated with higher percentage of lung tissue damage and the levels of acute phase proteins.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>гипокалиемия</kwd><kwd>пневмония</kwd><kwd>ренин-ангиотензин-альдостероновая система</kwd><kwd>ангио-тензинпревращающий фермент 2</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>hypokalemia</kwd><kwd>pneumonia</kwd><kwd>renin-angiotensin-aldosterone system</kwd><kwd>angiotensinconverting enzyme 2</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Временные методические рекомендации: профилактика, диагностика и лечение новой коронавирусной инфекции (COVID-19).
