Борьба с неспецифической инфекцией на фоне иммунодефицита у ВИЧ-инфицированных больных представляет собой сложную задачу. Стандартизированные протоколы лечения в настоящее время отсутствуют. Самым эффективным методом лечения гнойных кокситов остается двухэтапная технология с выполнением на первом этапе резекции тазобедренного сустава с установкой спейсера с антимикробными препаратами, на втором этапе — тотальное эндопротезирование тазобедренного сустава. Одним из путей уменьшения неудовлетворительных результатов и сокращения ревизионных вмешательств является разработка новых видов спейсеров для лечения такой патологии у пациентов с ВИЧ-инфекцией.Цель работы — на двух клинических примерах продемонстрировать возможность применения оригинальной конструкции антимикробного двухслойного артикулирующего спейсера, ранее разработанной для лечения пациентов с деструктивными формами туберкулезного коксита, в оперативном лечении больных неспецифическим инфекционным кокситом с ВИЧ-инфекцией.Материалы и методы. Ретроспективно оценены результаты лечения двух больных инфекционным кокситом, ассоциированным с ВИЧ-инфекцией, которым на первом этапе лечения применена оригинальная двухслойная конструкция цементного спейсера, насыщенного антимикробными препаратами в зависимости от индивидуальной чувствительности микробного агента. Для исследования эффективности примененного метода использовали результаты динамической оценки выраженности болевого синдрома по шкале ВАШ, функционального состояния поражённого сустава с помощью шкал HSS (англ.: Harris Hip Score), WOMAC (англ.: Western Ontario and McMaster Universities osteoarthritis Index) и лучевые данные пациентов в раннем послеоперационном периоде и через 12 мес. наблюдения.Результаты. Клинические наблюдения демонстрируют положительные результаты лечения пациентов с инфекционным кокситом, ассоциированным с ВИЧ-инфекцией. Применение разработанной конструкции спейсера позволило достичь эрадикации инфекции в зоне воспаления. В результате применения новой модели спейсера с выраженным антимикробным эффектом в первом клиническом случае удалось восстановить функцию сустава с 35 до 89 баллов по шкале HHS, с 79 до 14 баллов по шкале WOMAC, уменьшить болевой синдром с 7 до 1 балла по шкале ВАШ. Во втором случае результаты изменились с 32 до 91 баллов по шкале HHS, с 84 до 11 баллов по шкале WOMAC, с 6 до 0 баллов по шкале ВАШ.Обсуждение. На основании данных научных публикаций и собственных клинических наблюдений мы предполагаем, что при гнойных кокситах, ассоциированных с ВИЧ-инфекцией, одной из основных причин неудовлетворительных результатов двухэтапного эндопротезирования является недостаточная локальная концентрация антимикробных препаратов, вызванная несовершенством конструкции традиционных цементных спейсеров. Оригинальная конструкция спейсера позволяет создать более высокую концентрацию и может стать эффективной альтернативой традиционным методикам лечения.Заключение. Применение оригинальной конструкции антимикробного двухслойного артикулирующего спейсера в оперативном лечении двух пациентов с инфекционным неспецифическим кокситом привело к эрадикации инфекции, уменьшению болевого синдрома, восстановлению функциональности тазобедренного сустава.</p></abstract><trans-abstract xml:lang="en"><p>Introduction The fight with nonspecific infection in immunodeficient HIV-infected patients is challenging. There are no standardized treatment protocols yet. The most effective treatment method of purulent coxitis remains two-stage total hip arthroplasty with the first stage of joint resection and implantation of an antibiotic‑loaded cement spacer, and the second stage of total hip replacement. One of the ways to reduce poor results and revision interventions is the development of new types of spacers for treatment of coxitis in patients with HIV infection.The aim of the work is to demonstrate the effectiveness of a new method of surgical treatment of infectious coxitis in HIV-infected patients using an original design of an antibiotic-loaded articulating spacer in two  clinical cases.Materials and methods The treatment results of two HIV-positive patients with infectious coxitis, in whom an original two-layer design of an antibiotic-loaded cement spacer based on the individual bacterial sensitivity was applied at the first stage of treatment, were retrospectively evaluated. To study the effectiveness of this method we used the results of the dynamics of pain evaluation according to Visual Analogue Scale (VAS), the  functional state of the affected joint using Harris Hip Score (HSS), Western Ontario and McMaster University osteoarthritis Index (WOMAC) scale and radiological data of patients in the early postoperative period and after 12-month follow-up.Results Clinical cases demonstrate positive results of treatment of infectious coxitis associated with HIV infection. Application of the developed spacer design allowed eradication of bacterial infection. As a result of using of the new spacer model with an antimicrobial effect in the first clinical case it was possible to restore the joint function from 35 to 89 HHS points, from 79 to 14 WOMAC points, to reduce the pain syndrome from 7 to 1 VAS point; in the second patient from 32 to 91 HHS points, from 84 to 11 WOMAC points, to reduce the pain syndrome from 6 to 0 VAS points.Discussion Based on scientific reports and our own clinical cases, we hypothesize that in HIV-associated purulent coxitis, one of the main reasons for poor results after two-stage arthroplasty is insufficient local concentration of antimicrobial agents, caused by the imperfect design of traditional cemented spacers. The  original spacer design allows for a higher concentration and may become an effective alternative to traditional treatment methods.Conclusion Application of the developed technology of surgical treatment of infectious coxitis in  HIV‑positive  patients resulted in eradication of infection, reduction of pain syndrome, restoration of the hip joint functionality.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инфекционный коксит</kwd><kwd>ВИЧ-инфекция</kwd><kwd>двухэтапное эндопротезирование</kwd><kwd>спейсер</kwd><kwd>антимикробные препараты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>infectious coxitis</kwd><kwd>HIV infection</kwd><kwd>two-stage arthroplasty</kwd><kwd>spacer</kwd><kwd>antimicrobial agents</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">D'Angelo F, Monestier L, Zagra L.
