Исследование уровня прокальцитонина (ПКТ) одновременно с посевами крови на стерильность является важным дополнением в диагностическом алгоритме хронического остеомиелита.</p><p>Цель работы — выявить связь сывороточного ПКТ с микрофлорой, выделенной из крови, ран и свищей у пациентов с хроническим остеомиелитом.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведен ретроспективный анализ микрофлоры ран, посевов крови на стерильность и результатов исследования на ПКТ.</p></sec><sec><title>Результаты</title><p>Результаты. В микробном пейзаже ран, свищей и крови у пациентов с ПКТ менее 0,5 нг/мл и от 0,5 до 2,0 нг/мл преобладали грамположительные микроорганизмы. У пациентов с ПКТ от 2,0–10,0 и выше 10 нг/мл выделялись как грамположительные, так и грамотрицательные бактерии. Среди положительных культур крови на первом месте по частоте выделения штаммы S. epidermidis, далее следовали изоляты S. aureus, K. pneumoniae, S. agalacteae, S. hominis. ПКТ в крови у семи человек был выше 10 нг/мл, у 6 — от 2,0 до 10,0 нг/мл. У двух человек отмечен низкий уровень ПКТ, при этом в крови обнаружен инфекционный возбудитель.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. У пациентов с ПКТ менее 0,5 нг/мл в микрофлоре ран и свищей чаще всего встречаются грамположительные микроорганизмы. Доля пациентов со значениями ПКТ ≥ 2 нг/мл и грамотрицательными бактериями в очаге, была выше в сравнении с пациентами с грамположительной микрофлорой. Тем не менее, обнаруженная высокая корреляционная взаимосвязь между микробиоценозом ран пациентов и значениями прокальцитонина подтверждает ведущую роль грамположительных бактерий в развитии остеомиелита.</p></sec><sec><title>Заключение</title><p>Заключение. При положительных посевах крови уровень сывороточного ПКТ в большинстве случаев был выше 2,0 нг/мл. Наличие грамотрицательных бактерий в крови, также как и в ране, сопровождался значениями ПКТ выше 10 нг/мл.</p></sec></abstract><trans-abstract xml:lang="en"><p>Introduction The study of procalcitonin (PCT) levels simultaneously with blood cultures for sterility is an important addition to the diagnostic algorithm for chronic osteomyelitis detection.</p><p>Purpose of work is to study the relationship of serum PCT with the microflora isolated from blood, wounds and fistulas in patients with chronic osteomyelitis.</p><p>Materials and methods A retrospective analysis of wound microflora, blood cultures for sterility, and procalcitonin test results was performed.</p><p>Results Gram-positive microorganisms prevailed in the microbial tests from wounds, fistulas and blood in patients with PCT less than 0.5 ng/ml and from 0.5 to 2.0 ng/ml. In patients with PCT levels from 2.0– 10.0 and  above10 ng/ml, both gram-positive and gram-negative bacteria were isolated. Among positive blood cultures, S. epidermidis strains were the most frequently isolated, followed by S. aureus, K. pneumoniae, S. agalactae, and S. hominis isolates. PCT in the blood of seven patients was higher than 10 ng/ml; and six patients had it from 2.0–10.0 ng/ml. Two subjects had a low PCT level, but an infectious agent was detected in their blood.</p><p>Discussion In patients with PCT lower than 0.5 ng/ml, gram-positive microorganisms are most often found in the microflora of wounds and fistulas. The proportion of patients with PCT values ≥ 2 ng/ml and gram‑negative bacteria in the focus was higher compared to patients with gram-positive microflora. Nevertheless, the detected high correlation relationship between the microbiocenosis of patients' wounds and procalcitonin values confirms the leading role of gram-positive bacteria in the development of osteomyelitis.</p><p>Conclusion In positive blood cultures, the serum PCT level was usually higher than 2.0 ng/ml. The presence of  gram-negative bacteria in the blood, as well as in the wound, was accompanied by PCT values higher than 10 ng/ml.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический остеомиелит</kwd><kwd>прокальцитонин</kwd><kwd>микрофлора</kwd><kwd>резистентность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic osteomyelitis</kwd><kwd>procalcitonin</kwd><kwd>microflora</kwd><kwd>resistance</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">Миронов С.П., Цискарашвили А.В., Горбатюк Д.С.
