Исследование когортное, обсервационное продольное. I этап: одномоментный анализ медицинских карт пациентов с давностью COVID-19 12 мес. (анкета на постковидный синдром, анализы крови). II этап: повторное анкетирование, давность заболевания — 24 мес. Выделены тестовая (положительная полимеразная цепная реакция, 138 чел.) и контрольная (отрицательная полимеразная цепная реакция, 87 чел.) группы. Статистический анализ: пакет Statistica 13.5.0.17.Результаты. Через 1 год после COVID-19 частота проявлений постковидного синдрома составила (тестовая vs контрольная группы): астения 63 % vs 64 %; снижение качества жизни 59 % vs 56 %; респираторный синдром 60 % vs 49 %; артралгии 55 % vs 49 %; кардиальный синдром 47 % vs 46 %, (разница не достоверна); симптомы, связанные с женским полом (r=0,231-0,379), тяжестью COVID-19 (r=0,187-0,425); Д-димер (r=0,244-0,328). Через 2 года частота симптомов составила: астения 43 % vs 45 %; кардиальные симптомы 23 % vs 15 %; респираторные симптомы 18 % vs 22 %; кожные проявления 8 % vs 12 %; снижение качества жизни 7 % vs 9 %, разница не достоверна; симптомы, связанные с возрастом (r=0,208-0,402). На протяжении двух лет симптомы коррелировали с тромбоцитами (r=-0,322-0,403), ферментами печени (r=0,216-0,298), липидами крови (r=0,188-0,257).Заключение. Выраженность постковидного синдрома не зависит от результатов полимеразной цепной реакции на SARS-CoV-2. Частота кардиальных и респираторных синдромов через 2 года снижается в 2-3 раза; качество жизни улучшается. Астения — самый долгосрочный синдром. Факторы риска постковидного синдрома в течение 1-го года — тяжесть COVID-19, женский пол, уровень Д-димера; со 2-го года — возраст. В течение двух лет после COVID-19 требуется контроль ферментов печени, липидного спектра, тромбоцитов.</p></abstract><trans-abstract xml:lang="en"><p>The aim - studying the dynamics of symptoms of post-COVID syndrome (depending on the results of depending on the results of the polymerase chain reaction for SARS-CoV-2) and the factors influencing it.Materials and methods. A study is a cohort, observational longitudinal. Stage I: snapshot analysis of medical records of patients with COVID-19 disease history 12 months. (questionnaire for post-COVID syndrome, blood tests). Stage II: questionnaire repeat, disease history — 24 months. There were test (positive polymerase chain reaction, 138 people) and control (negative polymerase chain reaction, 87 people) groups. Statistical analysis: package Statistica 13.5.0.17.Results. 1 year after COVID-19, the frequency of manifestations of post-COVID syndrome was (test vs control group): asthenia 63 % vs 64 %, decreased quality of life 59 % vs 56 %, respiratory syndrome 60 % vs 49 %, arthralgia 55 % vs 49 %, cardiac syndrome 47 % vs 46 % (the difference is not significant); symptoms are associated with female gender (r=0.231- 0.379), severity of COVID-19 (r=0.187-0.425), D-dimer (r=0.244-0.328). After 2 years, the frequency of symptoms was: asthenia 43 % vs 45 %, cardiac symptoms 23 % vs 15 %, respiratory symptoms 18 % vs 22 %, skin manifestations 8 % vs 12 %, decreased quality of life 7 % vs 9 %, the difference is not significant; symptoms are associated with age (r=0.208-0.402). During two years, symptoms have been correlating with platelets (r=-0.322-0.403), liver enzymes (r=0.216-0.298), blood lipids (r=0.188-0.257).Conclusions. The severity of post-COVID syndrome does not depend on the results of the polymerase chain reaction for SARS-CoV-2. The frequency of cardiac and respiratory syndromes after 2 years decreases by 2-3 times; quality of life improves. Asthenia is the most long-term syndrome. Risk factors for post-COVID syndrome during the 1st year — severity of COVID-19, female gender, D-dimer level; from the 2nd year — age. For two years after COVID-19, monitoring of liver enzymes, lipids, and platelets is required.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>постковидный синдром</kwd><kwd>динамика</kwd><kwd>полимеразная цепная реакция</kwd><kwd>факторы риска</kwd></kwd-group><kwd-group xml:lang="en"><kwd>post-COVID syndrome</kwd><kwd>dynamics</kwd><kwd>polymerase chain reaction</kwd><kwd>risk factors</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">NICE guideline [NG188].
