The insufficient efficacy of all available treatment modalities remains a major concern. Among the most effective approaches are genetically engineered therapy and bisphosphonate treatment. Pamidronate is the most frequently reported option in scientific publications. However, given pamidronates’ lower efficacy compared to zoledronic acid, we developed a treatment protocol that includes zoledronic acid at a dose of 0.05 mg/kg every 3 months, three infusions in total, along with active vitamin D metabolites and calcium carbonate.</p> <p><bold>AIM:</bold> This study aimed to demonstrate the efficacy of zoledronic acid in the treatment of chronic nonbacterial osteomyelitis.</p> <p><bold>METHODS:</bold><italic> </italic>The study included 22 children aged 6 to 17 years. A prospective pilot study was conducted to assess the efficacy of zoledronic acid in children with chronic recurrent multifocal osteomyelitis. All patients underwent biopsy with morphological and microbiological verification of the diagnosis, as well as laboratory and imaging assessments before and 3, 6, and 12 months after treatment. Clinical disease activity was assessed using a visual analog scale for pain and the PedsQL 4.0 quality of life questionnaire.</p> <p><bold>RESULTS:</bold><italic> </italic>Preliminary treatment outcomes in patients receiving this regimen are promising. Pain was significantly reduced, quality of life improved, and the number of bone lesions decreased, with clinical remission achieved in all patients.</p> <p><bold>CONCLUSION:</bold><italic> </italic>Zoledronic acid rapidly inhibits osteoclast activity, leading to both clinical and radiological remission, as evidenced by decreased pain, reduction of bone marrow edema on MRI, and sclerosis of lytic lesions. Given the reduced osteoclast activity in the post-injection period, this therapy must be combined with active vitamin D metabolites and calcium carbonate to maintain calcium-phosphorus homeostasis.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold><bold> </bold>В настоящее время не существует этиотропной терапии хронического небактериального остеомиелита. Недостаточная эффективность всех широко используемых видов терапии остаётся актуальной проблемой. Наиболее эффективными методами лечения являются генно-инженерная терапия и терапия бисфосфонатами. Чаще всего в литературе встречается схема лечения памидронатом. В связи с тем, что эффективность памидроната ниже по сравнению с золедроновой кислотой, нами была разработана схема лечения, которая включает золедроновую кислоту 0,05 мг/кг один раз в 3 месяца трёхкратно, активные метаболиты витамина D и карбонат кальция.</p> <p><bold>Цель.</bold> Продемонстрировать эффективность препаратов золедроновой кислоты в терапии хронического небактериального остеомиелита.</p> <p><bold>Материалы</bold><bold> </bold><bold>и</bold><bold> </bold><bold>методы.</bold> В исследование были включены 22 ребёнка в возрасте от 6 до 17 лет. Проведено проспективное пилотное исследование эффективности терапии золедроновой кислотой у детей с хроническим рецидивирующим многоочаговым остеомиелитом. Всем пациентам проводилась биопсия с морфологической и микробиологической верификацией диагноза, лабораторные и лучевые методы исследования до лечения и в последующем через 3, 6, 12 месяцев. Оценка клинической активности заболевания проводилась при помощи визуальной аналоговой шкалы боли и опросника качества жизни PedsQL 4.0</p> <p><bold>Результаты.</bold> Предварительные результаты лечения пациентов, получавших данную схему терапии, достаточно перспективны. Отмечается значимое снижение болевого синдрома и улучшение качества жизни, а также уменьшение количества очагов поражения костной ткани с достижением клинической ремиссии у всех пациентов.</p> <p><bold>Заключение.</bold> Золедроновая кислота быстро ингибирует активность остеокластов, что приводит к клинической и рентгенологической ремиссии в виде снижения болевого синдрома и отёка костной ткани на МРТ, а также склерозированию литических очагов. Обязательна комбинация данного лечения с активными метаболитами витамина D и карбонатом кальция для поддержания кальций-фосфорного обмена в связи с низкой активностью остеокластов в постинъекционном периоде.</p></trans-abstract><kwd-group xml:lang="en"><kwd>zoledronic acid</kwd><kwd>chronic recurrent multifocal osteomyelitis</kwd><kwd>chronic nonbacterial osteomyelitis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>золедроновая кислота</kwd><kwd>хронический рецидивирующий многоочаговый остеомиелит</kwd><kwd>хронический небактериальный остеомиелит</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Zhao DY, McCann L, Hahn G, Hedrich CM.
