Инъекции глюкокортикостероидов широко применяются в клинической практике. Одним из представителей данной группы является бетаметазон. Его эффективность при внутрисуставном введении неоспорима. Существуют особые указания о дозировке и частоте применения препарата. К сожалению, распространена практика введения глюкокортикостероидов с нарушением рекомендаций производителя и в сочетании с анестетиками. Вместе с тем бытует мнение о неблагоприятном влиянии на хрящевую ткань как непосредственно раствора бетаметазона, так и при его использовании в указанной комбинации.</p></sec><sec><title>Цель</title><p>Цель. Оценить влияние еженедельного внутрисуставного введения бетаметазона на основе гистологического исследования препаратов коленных суставов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведены морфологические исследования препаратов правых коленных суставов трёх основных групп кроликов: с одно-, трёх- и шестикратным еженедельным введением бетаметазона и группы сравнения (интактные левые коленные суставы).</p></sec><sec><title>Результаты</title><p>Результаты. Гистологические препараты группы сравнения и основной группы с однократным введением препарата не имели каких-либо изменений в строении диартрозов. В суставах животных, которым были осуществлены трёхкратные еженедельные внутрисуставные инъекции бетаметазона, наблюдались дистрофические и некротические изменения, затрагивающие все изучавшиеся морфологические компоненты (в сравнении с группой с однократным введением площадь явлений дистрофии и некроза хрящевой ткани была больше на 10,05 ± 0,75 % (p меньше 0,05), субхондральной кости – на 8,11 ± 0,5 % (p меньше 0,001), синовиальной оболочки – на 6,25 ± 0,32 % (p меньше 0,05)). В группе с шестикратным введением препарата отмечались ещё более выраженные изменения. Площадь некротических изменений хряща оказалась на 6,39 ± 0,75 % больше, чем в группе с трехкратным введением (p меньше 0,001), субхондральной кости – на 11,18 ± 0,5 % (p меньше 0,001), синовиальной оболочки – на 6,12 ± 0,32 % (p меньше 0,001).</p></sec><sec><title>Заключение</title><p>Заключение. Воспалительная клеточная инфильтрация структур сустава во всех наблюдениях отсутствовала, что свидетельствует об асептической природе некроза тканей. Получены свидетельства связи между увеличением частоты внутрисуставных инъекций бетаметазона и выраженностью дистрофических и некротических изменений морфологических компонентов сустава. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Glucocorticosteroid injections have been widely used in clinical practice. Betamethasone is one of the agents of this group of drugs. Its efficacy and therapeutic effect with intra-articular administration are undeniable. There are special instructions on the dosage and frequency of use of the drug but unfortunately there are cases of its wrong administration. There is also an evidence of an adverse effect on cartilage both of the drug itself and its combination with local anesthetics.</p></sec><sec><title>Aim</title><p>Aim. Evaluation of the results of different weekly intra-articular protocols of betamethasone administration on histological preparations of rabbit knee joints.</p></sec><sec><title>Methods</title><p>Methods. Histological preparations of the right knee joints of three groups of rabbits were studied: after one, three, and six administrations of betamethason per week and the control intact left knee joints.</p></sec><sec><title>Results</title><p>Results. Histological preparations of the control group and the group with a single weekly administration of the drug did not have any changes in the structure of diarthrosis. Dystrophic and necrotic changes affecting all morphological components were observed in the joints of animals that received intra-articular injections of betamethason three times a week (compared to a single injection, the area of dystrophy and necrosis of the cartilage was greater by 10.05 ± 0.75 % (p less 0.05), of subchondral bone by 8.11 ± 0.5 % (p less 0.001), and of synovium by 6.25 ± 0.32 % (p less 0.05). The group with six injections of the drug per week had the most pronounced changes. The area of necrotic changes of the cartilage was greater by 6.39 ± 0.75 % than in the group with three injections per week (p less 0.001), of subchondral bone by 11.18 ± 0.5 % (p less 0.001), of synovium by 6.12 ± 0.32 % (p less 0.001).</p></sec><sec><title>Discussion</title><p>Discussion. Inflammatory cell infiltration of joint structures was absent in all cases. It indicates an aseptic nature of tissue necrosis. Evidence has been obtained between the increase in the frequency of intra-articular injections of betamethasone and the severity of dystrophic and necrotic changes in all morphological components of the joint.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>глюкокортикостероиды</kwd><kwd>бетаметазон</kwd><kwd>внутрисуставное введение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>glucocorticosteroids</kwd><kwd>betamethasone</kwd><kwd>intra-articular injection</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">Increased chondrocyte death after steroid and local anesthetic combination / B.
