Определить диагностическую значимость лабораторных показателей общего анализа крови в прогнозе длительности стационарного лечения при внебольничной пневмонии (ВП), вызванной Klebsiella pneumoniae.</p></sec><sec><title>   Материалы и методы</title><p>   Материалы и методы. Дизайн исследования: одноцентровое сплошное ретроспективное исследование по типу серии случаев; объекты исследования: 52 пациента (все ВИЧ-отрицательные), 55,8 % (29/52) мужского и 44,2 % (23/52) женского пола с диагнозом ВП, вызванной K. pneumoniae; продолжительность исследования: с 2016 по 2022 год; первичная конечная точка исследования: выздоровление и выписка больного из стационара; описание методов: анализ парных таблиц сопряжённости с помощью критерия Пирсона (χ2), (без поправки Иэйтса на непрерывность), логистическая регрессия (простая и множественная).</p></sec><sec><title>   Результаты</title><p>   Результаты. Точки отсечения (статистически значимые пороговые значения) вероятности стационарного лечения более 10 дней при ВП, вызванной K. pneumonia, составляли: для содержания лимфоцитов – 2,01·109/л, для содержания моноцитов – 0,68·109/л (при их снижении ниже данных значений риск увеличивался), для СОЭ – 52 мм/час (риск возрастал при увеличении значения параметра).</p></sec><sec><title>   Заключение</title><p>   Заключение. Прогноз длительности госпитализации более 10 дней при лечении ВП, вызванной K. pneumoniae, можно с высокой степенью вероятности определять с помощью трёх лабораторных показателей общего анализа крови или их сочетания (содержание лимфоцитов, моноцитов и СОЭ).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Aim</title><p>   Aim. To determine the diagnostic significance of laboratory blood parameters in predicting the duration of inpatient treatment for community-acquired pneumonia (CAP) caused by Klebsiella pneumoniae.</p></sec><sec><title>   Materials and methods</title><p>   Materials and methods. Study design: single-center, continuous, retrospective case series study; study subjects: 52 patients (all HIV-negative), 55.8 % (29/52) male and 44.2 % (23/52) female, diagnosed with CAP caused by K. pneumoniae; study duration: from 2016 to 2022; primary endpoint: recovery and discharge of the patient from hospital; Description of methods: analysis of paired contingency tables – Pearson's criteria (χ2), (without Yates's correction for continuity) for df = 1, logistic regression (simple and multiple).</p></sec><sec><title>   Results</title><p>   Results. Statistically significant threshold values predictive of hospitalization exceeding 10 days were identified as follows: lymphocyte count ≤ 2.01 × 109/L, monocyte count ≤ 0.68 × 109/L (lower values associated with increased risk), and erythrocyte sedimentation rate (ESR) ≥ 52 mm/h (higher values associated with increased risk).</p></sec><sec><title>   Conclusion</title><p>   Conclusion. The prognosis for the duration of hospitalization longer than 10 days during treatment for CAP caused by K. pneumoniae can be determined with a high degree of probability using three laboratory parameters of a complete blood count or a combination of them (lymphocyte, monocyte, and ESR levels).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Klebsiella pneumoniae</kwd><kwd>лимфоциты</kwd><kwd>моноциты</kwd><kwd>СОЭ</kwd><kwd>прогноз</kwd><kwd>логистическая регрессия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Klebsiella pneumoniae</kwd><kwd>lymphocytes</kwd><kwd>monocytes</kwd><kwd>erythrocyte sedimentation rate (ESR)</kwd><kwd>prognosis</kwd><kwd>logistic regression</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проводилось без участия спонсоров</funding-statement><funding-statement xml:lang="en">This study was not sponsored</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Podschun R., Ullmann U.
