Современным направлением научных исследований является поиск методов лечения и вспомогательной поддержки пациентов с остеоартритом с улучшенным профилем безопасности и переносимости, среди которых интерес представляют парафармацевтики с хондропротекторным действием.</p></sec><sec><title>Цель работы</title><p>Цель работы. Оценка эффективности и безопасности применения парафармацевтика Хондрогард Квадро у пациентов с остеоартритом коленного сустава II-III стадии по Келлгрену – Лоуренсу (Kellgren – Lawrence) и функциональной недостаточностью суставов 1-2 степени.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В неинтервенционную наблюдательную программу включено 47 пациентов (14 мужчин и 33 женщины в возрасте 59-74 года) с остеоартритом коленного сустава II-III стадии по Келлгрену – Лоуренсу и функциональной недостаточностью 1-2 степени. В контрольную группу вошли 15, в основную группу – 32 пациента, получавшие стандартную терапию по поводу остеоартрита коленного сустава (нестероидные противовоспалительные препараты) курсами до 10 дней. Пациенты основной группы парафармацевтик с хондропротективным действием Хондрогард Квадро – по 2 таблетки 2 раза в день во время еды утром и днем в течение одного месяца после приема нестероидных противовоспалительных препаратов. Выполнены оценка динамики боли по визуально-аналоговой шкале, тяжести остеоартрита по индексу Лекена, качества жизни по опроснику SF-36 до и после терапии, глобальная оценка эффективности терапии врачом и пациентом по пятибалльной шкале Ликерта. Выполнено рентгенологическое исследование коленного сустава. Представлена динамика содержания С-реактивного белка, фактора некроза опухоли альфа, интерлейкина-6, N-концевого пропептида коллагена IIα, N-остеокальцина, олигомерного матричного белка хряща, 25(ОН)D3, витамина К2 в крови, uCTX-1, дезоксипиридинолина, uCTX-II в моче методами иммуноферментного и иммунохемилюминесцентного анализов, а также высокоэффективной жидкостной хроматографии и масс-спектрометрии. Безопасность препарата оценивали по шкалам Всемирной организации здравоохранения и Наранжо.</p></sec><sec><title>Результаты</title><p>Результаты. В основной группе после приема парафармацевтика с хондропротекторным действием разница с исходными показателями выраженности боли была более существенной по сравнению с контрольной группой: динамика интенсивности боли по визуально-аналоговой шкале при движении (-85,1% против -73,8% в контрольной группе) и в покое (-86% против -58,1% в контрольной группе), по индексу Лекена (-83,5% против -61,8% в контрольной группе). В основной группе отметили наиболее выраженное улучшение качества жизни пациентов по опроснику SF-36. На сороковой день программы выявлено значимое увеличение оценки общей эффективности и переносимости терапии со стороны пациента и врача по шкале Ликерта по сравнению с контрольной группой. У пациентов основной группы отмечено снижение всех биомаркеров в крови при увеличении уровней 25(ОН)D3 и витамина К2 в крови и наличии межгрупповых различий по всем лабораторным тестам к сороковому дню программы. Нежелательных явлений при приеме парафармацевтика зарегистрировано не было.</p></sec><sec><title>Заключение</title><p>Заключение. Парафармацевтик с хондропротективным действием Хондрогард Квадро может быть рекомендован в качестве вспогательной поддержки пациентов с остеоартритом коленного сустава с умеренно выраженным или слабым болевым синдромом при обнаружении маркеров деградации и кальцификации суставного хряща. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. The current focus of scientific research is to find treatment methods and auxiliary support for patients with OA with an improved safety and tolerability profile, including parafarmaceuticals with chondroprotective effects.</p></sec><sec><title>Objective</title><p>Objective. The purpose of the study was to evaluate the efficacy and safety of the parafarmaceutical Chondroguard Quadro in patients with stage II-III (K-L) OA of the knee and grade 1-2 joint functional insufficiency (FI).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The non–interventional follow-up program included 47 patients (14 men and 33 women aged 59-74 years) with stage II-III (K-L) and grade 1-2 FI. The control group (CG) included 15, and the main group (MG) included 32 patients who received standard therapy for OA (NSAIDs) for courses of up to 10 days. The MG patients parafarmaceutical with chondroprotective effects Chondroguard Quadro take 2 tablets 2 times per day with meals in the morning and afternoon for 1 month after taking NSAIDs. The dynamics of pain were assessed using the VAS, the severity of OA using the Leken index, the quality of life (QL) using the SF-36 questionnaire before and after treatment, the global assessment of therapy effectiveness by the doctor and the patient using the 5-point Likert scale. A radiological examination of the knee was performed. The dynamics of CRP, TNF-α, interleukin-6, PIIANP, N-osteocalcin, COMP, 25(OH)D3, vitamin K2, as well as uCTX-1, deoxypyridinoline, uCTX-II in urine by ELISA, CLIA and HPLC/MS. The safety of parafarmaceutical with chondroprotective effects was evaluated using the WHO and Naranjo scales.</p></sec><sec><title>Results</title><p>Results. In MG after taking parafarmaceutical with chondroprotective effects, the difference from the initial indicators of pain severity was more significant compared to CG: the dynamics of pain intensity according to VAS during movement (-85.1% vs. -73.8% in CG) and at rest (-86% vs. -58.1% in CG), according to the Leken index (-83.5% vs. -61.8% in CG). In MG the most pronounced improvement of the QL of patients was noted using the SF-36. On the 40th day of the program, a significant increase in the patient's and doctor's assessment of the overall effectiveness and tolerability of the therapy was observed using the Likert scale compared to the CG. In patients with OA, there was a significant decrease in all biomarkers in the blood, an increase in the levels of 25(OH)D3 and vitamin K2 in the blood, and there were intergroup differences in all laboratory tests by the 40th day of the program. No adverse events were reported during the use of parafarmaceutical with chondroprotective effects.</p></sec><sec><title>Conclusion</title><p>Conclusion. Parafarmaceutical with chondroprotective effects Chondroguard Quadro can be recommended as an adjuvant support for patients with OA of the knee with moderate to mild pain syndrome when markers of cartilage degradation and calcification are detected.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>остеоартрит</kwd><kwd>кальцификация хряща</kwd><kwd>парафармацевтик с хондропротективным действием</kwd></kwd-group><kwd-group xml:lang="en"><kwd>osteoarthritis</kwd><kwd>calcification of cartilage</kwd><kwd>parapharmacetical with hondroprotective effects</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">Peat G., Thomas M.
