Abstract
Objective: investigate epidemiology of infectious complications, intensity of antibacterial therapy, and features of the systemic inflammatory response in patients with prolonged disorders of consciousness.Materials and methods: retrospective case histories analysis of 102 patients with prolonged disorders of consciousness who were treated in the department of anesthesiology and intensive care of Polenov Neurosurgical Institute from 2010 to 2019.Results: during hospitalization all patients (100%) had signs of tracheobronchitis, 86 patients (84,3%) had urinary tract infection, 34 (33,3%) pneumonia, 10 patients (9,8%) meningoventriculitis, and in 9 (8,8%) cases sepsis was diagnosed. Identified bacterial complications required systemic antibacterial therapy. With an average length of hospital stay of 51±42 days, duration of antibiotic therapy was 37±41 days. One-component therapy was applied in half of the cases (54%), slightly less often (43,2%) treatment consisted of two antibiotics, in some cases patient’s condition required prescription of three antibiotics (2,8%). Even in the absence of a focus of infection, temperature and laboratory markers of inflammation in blood samples of patients with prolonged disorders of consciousness were higher than the reference values. CRP was increased with addition of any bacterial complications. Count of white blood cells significantly increased only in case of pneumonia and sepsis. Procalcitonin test was positive in 16,6% observations of urinary tract infection, 30,4% of pneumonia, and 28% of meningoventriculitis.Conclusion: most informative proinflammatory marker of bacterial complications in patients with prolonged disorders of consciousness was CRP. Mild leukocyte response can be explained by immunosuppression in long-term ill patients. Limited value of procalcitonin test may be due to the insufficiency of the semi-quantitative method sensitivity with a threshold level of 0,5 ng/ml, as well as reduced proinflammatory response to local infection in patients with prolonged disorders of consciousness as a result of massive antibacterial therapy, colonization of opportunistic microflora and presence of sympathicotonia (non-infectious systemic inflammatory reaction).

Summary
Поленова – филиал Национального медицинского исследовательского центра им. Резюме Цель: изучить эпидемиологию инфекционных осложнений, интенсивность антибактериальной терапии и особенности системного воспалительного ответа у больных с длительным нарушением сознания. Материалы и методы: проведен ретроспективный анализ историй болезни 102 пациентов с длительным нарушением сознания, проходивших лечение в отделении анестезиологии-реанимации Российского научноисследовательского нейрохирургического института им. При продолжительности пребывания больного в стационаре в среднем 51±42 дня продолжительность антибактериальной терапии составила в среднем 37±41 день. Даже в отсутствие очага инфекции температура и лабораторные маркеры воспаления в крови у больных с длительным нарушением сознания были выше референсных показателей. Заключение: наиболее информативным провоспалительным маркером в диагностике бактериальных осложнений у больных с длительным нарушением сознания оказался С-реактивный белок.
