Клинические проявления болезни, предположительно, зависят от остаточной активности фермента лизосомной кислой липазы. Глубокий дефицит фермента – болезнь Вольмана – проявляется в первые месяцы жизни. Болезнь представлена диспептическими нарушениями в виде рвоты и диареи, отсутствием прибавки в весе, гепатоспленомегалией, наличием кальцинатов в надпочечниках. При естественном развитии болезни Вольмана дети погибают в течение первых 6 мес. в результате истощения на фоне синдрома мальабсорбции в сочетании с прогрессирующей недостаточностью функций печени и надпочечников. Частичный дефицит лизосомной кислой липазы проявляется в более старшем возрасте и называется болезнью накопления эфиров холестерина. Ее клинические проявления включают гепатоспленомегалию, повышение трансаминаз, гиперхолестеринемию и, в некоторых случаях, гипертриглицеридемию. Основная причина смерти при естественном течении болезни накопления эфиров холестерина – печеночная недостаточность. Несвоевременная диагностика болезни приводит к ее прогрессированию с развитием необратимых повреждений печени. Для выявления малосимптомных пациентов большое значение имеет реализация программ массового скрининга с определением уровня холестерина в детском возрасте. В статье представлен клинический случай пациентки в возрасте 3 лет. В результате молекулярно-генетического исследования у нее была обнаружена мутация в экзоне 8 гена LIPA: синонимичный вариант NM_000235.3:c.894G&gt;A в гомозиготном состоянии. Также было установлено, что оба родителя девочки имеют данный тип мутации в гетерозиготном состоянии. Пациентке был назначен прием препарата себелипаза альфа из расчета 1 мг/кг 1 раз в 14 дней. Переносимость лечения была хорошей. Благодаря ранней верификации диагноза и своевременно начатой патогенетической терапии прогноз течения ДЛКЛ, продолжительность и качество жизни ребенка были признаны благоприятными.Повышение осведомленности врачей наряду с внедрением эффективных скрининговых программ по своевременному выявлению дислипидемии у детей способствуют своевременной диагностике заболевания и раннему началу патогенетической терапии, что позволяет увеличить продолжительность жизни пациентов с дефицитом лизосомной кислой липазы и улучшить качество их жизни.</p></abstract><trans-abstract xml:lang="en"><p>Lysosomal acid lipase deficiency (LAL-D) is a rare, progressive, autosomal recessive disease, which develops due to impaired degradation and subsequent intra-lysosomal accumulation of triglycerides and cholesterol esters causing dyslipidemia. The clinical manifestations of the disease presumably depend on the residual activity of the enzyme, lysosomal acid lipase. A profound deficiency of the enzyme known as Wolman’s disease has an onset in the first 6 months of life. The disease reveals itself by dyspeptic disorders in the form of vomiting and diarrhea, lack of weight gain, hepatosplenomegaly, and adrenal calcification. If the Wolman’s disease is not treated, children die within the first 6 months as a result of exhaustion caused by malabsorption syndrome combined with progressive deterioration of liver and adrenal glands. Partial deficiency of lysosomal acid lipase manifests itself at a later age and is called cholesterol ester storage disease. Its clinical presentations include hepatosplenomegaly, elevated transaminases, hypercholesterolemia, and, in some cases, hypertriglyceridemia. Liver failure is the main cause of death in the natural course of cholesterol ester storage disease. Delayed diagnosis of the disease leads to its progression causing irreversible liver damage. The implementation of mass screening programs with the determination of cholesterol levels in childhood is critical to identifying asymptomatic patients.The article presents a clinical case of a patient aged 3 years. The molecular genetic testing showed a mutation in exon 8 of the LIPA gene: NM_000235.3:c.894G&gt;A synonymous variant in the homozygous state. It was also found that both parents of the girl had this type of mutation in the heterozygous state. The patient was prescribed sebelipase alfa in a dose of 1 mg/kg once every 14 days. The treatment was well tolerated. Due to the early verification of the diagnosis and timely pathogenetic therapy, the prognosis of the course of LAL-D, the duration and quality of life of the child were considered to be favourable.Raising the awareness of doctors along with the introduction of effective screening programs for the timely detection of dyslipidemia in children contributes to timely diagnosis and early initiation of pathogenetic therapy, which can increase the life expectancy of patients with lysosomal acid lipase deficiency and improve their quality of life.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>печень</kwd><kwd>дефицит лизосомной кислой липазы</kwd><kwd>болезнь Вольмана</kwd><kwd>болезнь накопления эфиров холестерина</kwd><kwd>себелипаза альфа</kwd><kwd>клиническое наблюдение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>liver</kwd><kwd>lysosomal acid lipase deficiency</kwd><kwd>Wolman’s disease</kwd><kwd>cholesterol ester storage disease</kwd><kwd>sebelipase alfa</kwd><kwd>clinical observation</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">Zhang H.
