Однако результаты проведенных на данный момент исследований неоднородны, а целесообразность измерения сывороточного ферритина всем стационарным пациентам, в том числе с COVID‑19, ставится под сомнение. В исследование были включены результаты измерения сывороточного ферритина у 761 взрослого пациента, из которых у 634 в основной группе был подтвержден COVID‑19, а 127 пациентов из группы сравнения были госпитализированы с другими диагнозами. Различия концентрации сывороточного ферритина в основной группе (COVID‑19 «+»: выжившие: Ме 295,2, 95% ДИ: 353,8–449,1 мкг/л, умершие Ме 285,9, 95% ДИ: 309,9–628,9 мкг/л) и в группе сравнения (COVID‑19 «-»: выжившие Ме 267,2: 95% ДИ 268,2–526,0 мкг/л, умершие Ме 197,7, 95% ДИ: 110,3–529,0 мкг/л), в зависимости от исходов заболевания, были статистически не значимы. При этом в когорте умерших сывороточный ферритин выше 500 мкг/л при COVID‑19 встречался чаще в 23,75 раза, а в когорте с концентрацией ферритина выше 1500 мкг/л – в 17,75 раз по сравнению с ферритином в группе стационарных пациентов без COVID‑19. Полученные нами результаты указывают на нецелесообразность измерения сывороточного ферритина для всех стационарных пациентов, однако подтверждают тот факт, что селективное измерение сывороточного ферритина у пациентов с тяжелым течением различных, особенно инфекционных заболеваний, позволяет выявить категорию пациентов с высоким риском развития гипервоспаления.</p></abstract><trans-abstract xml:lang="en"><p>Serum ferritin is considered one of the predictors of severe forms of diseases and an increased mortality risk in patients with various diseases. However, the results of the studies performed to date are not heterogeneous and the usefulness of measuring serum ferritin in all inpatients, including those with COVID‑19, is being questioned. The study included the results of measuring serum ferritin in 761 adult patients, of which in the main group 634 were confirmed with COVID‑19, and 127 patients from the comparison group were hospitalized with other diagnoses. Differences in serum ferritin concentration in the main group (COVID‑19 “+”: survivors: Me 295.2, 95% CI: 353.8–449.1 µg/l, non-survivors Me 285.9, 95% CI: 309.9–628.9 µg/l) and in the comparison group (COVID‑19 “-”: survivors Me 267.2: 95% CI 268.2–526.0 µg/l, non-survivors Me 197.7, 95% CI: 110.3–529.0 µg/l) depending on the outcomes of the disease were not statistically significant. At the same time, in the cohort of the non-survivors, serum ferritin above 500 µg/l with COVID‑19 was 23.75 times more common, and in the cohort with a ferritin concentration above 1500 µg/l, 17.75 times more common than ferritin in the group of inpatients without COVID–19. Our results indicate the impracticality of measuring serum ferritin for all inpatients; however, they confirm the fact that selective measurement of serum ferritin in patients with severe course of diseases, especially infectious diseases, makes it possible to identify a category of patients with a high risk of developing hyperinflammation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сывороточный ферритин</kwd><kwd>стационарные пациенты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>serum ferritin</kwd><kwd>inpatients</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">Хронология действий ВОЗ по борьбе с COVID 19. https://www.who.int/ru/news/ item/29–06–2020-covidtimeline.</mixed-citation><mixed-citation xml:lang="en">Timeline of WHO's response to COVID-19. https://www.who.int/en/news/item/29- 06-2020-covidtimeline.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Lachmann G., Knaak C., Vorderwülbecke G. et al.
