Хроническое течение аутоиммунного гепатита (АИГ) требует длительной иммуносупрессивной терапии, что может привести к таким побочным эффектам, как нарушение минеральной плотности костной ткани (МПК). Данных по оценке минерализации костной ткани у детей с АИГ недостаточно.</p></sec><sec><title>Цель работы</title><p>Цель работы: определить изменения МПК у детей с АИГ на фоне иммуносупрессивной терапии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследован 41 ребёнок, из них 24 девочки, с установленным диагнозом АИГ. У 18 больных диагноз был установлен впервые, и до момента госпитализации они терапию не получали, 15 детей принимали глюкокортикостероиды длительностью до 6 мес и 8 больных — 6 мес и более. Проведён анализ клинико-лабораторных данных: возраст и пол больных, длительность течения болезни и лечения, определение индекса массы тела, активности аланин- и аспартатаминотрансферазы, содержание в крови общего иммуноглобулина G, остеокальцина, N-терминального пропептида проколлагена 1-го типа, β-изомера С-концевых телопептидов коллагена 1-го типа, кальция, фосфора, паратгормона, витамина D, а также данных инструментального обследования (рентгеноденситометрия поясничного отдела позвоночника, фиброэластометрия печени).</p></sec><sec><title>Результаты</title><p>Результаты. У детей с АИГ в возрасте 16 лет и старше отмечались более низкие показатели Z-score МПК по данным денситометрии (p = 0,015). Значимых различий Z-score МПК по данным денситометрии в зависимости от длительности терапии не выявлено. Обнаружена взаимосвязь показателей Z-score МПК и уровней остеокальцина (р = 0,026) и N-терминального пропептида проколлагена 1-го типа в сыворотке крови (p = 0,035).</p></sec><sec><title>Заключение</title><p>Заключение. АИГ — хроническое заболевание печени, сопровождающееся нарушениями МПК, в том числе у детей, что определяет необходимость своевременного анализа состояния костного ремоделирования, а также назначения сопроводительной терапии препаратами кальция и витамина D.</p></sec><sec><title>Участие авторов</title><p>Участие авторов: Парахина Д.В., Мовсисян Г.Б., Потапов А.С. — концепция и дизайн исследования; Парахина Д.В., Мовсисян Г.Б., Семикина Е.Л. — сбор и обработка материала; Парахина Д.В., Мовсисян Г.Б. — написание текста; Фисенко А.П. — редактирование.

The chronic course of autoimmune hepatitis requires long-term immunosuppressive therapy, which can lead to side effects such as impairement of bone mineral density (BMD). Currently, there are no data assessing bone mineralization in children with autoimmune hepatitis.</p></sec><sec><title>Aim</title><p>Aim. To determine the bone mineral density by densitometry and bone remodelling biochemical markers in children with autoimmune hepatitis.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 41 child with autoimmune hepatitis. 18 patients were diagnosed for the first time and received no treatment before admission, 15 children took glucocorticosteroids up to 6 months and 8 patients received them for 6 months or more. The study required clinical: age and sex of patients, duration both of the disease and treatment, body mass index, laboratory (ALT, AST, total immunoglobulin G, osteocalcin, procollagen type 1 N-terminal propeptide (P1NP), βCrossLaps, calcium, phosphorus, parathormone, vitamin D), instrumental examination (lumbar radiodensitometry, liver elastography).</p></sec><sec><title>Results</title><p>Results. Children with autoimmune hepatitis at the age of 16 years and older had lower densitometry Z-score (p = 0.015). There was no statistically significant difference between bone mineral density Z-score and the treatment duration. BMD Z-score was established to correlate with P1NP in blood serum (p = 0.035) and osteocalcin (p = 0.026).</p></sec><sec><title>Conclusion</title><p>Conclusion. Autoimmune hepatitis is a chronic liver disease, associated with the risk for bone density mineral disorders, including in children. This requires timely assessment of one remodelling state, as well as calcium and vitamin D prescription for concomitant treatment.</p></sec><sec><title>Contribution</title><p>Contribution: Parakhina D.V., Movsisyan G.B., Potapov A.S. — research concept and design of the study; Parakhina D.V., Movsisyan G.B., Semikina E.L. — collection and processing of material; Parakhina D.V., Movsisyan G.B. — writing the text; Fisenko A.P. — editing the text.
