Несмотря на различия в методах диагностики, в последние годы появилась серия исследований в которых была выявлена тесная связь между саркопенией и НАЖБП. Саркопения и НАЖБП связаны целым рядом общих патогенетических механизмов, которые рассмотрены в представленной статье, включая роль резистентности к инсулину как на уровне печени, так и на уровне мышц, гормональный дисбаланс, роль системного воспаления, нарушения регуляции миокинов, дефицит витамина Д, роль неправильного питания и гиподинамии, роли гепатокинов и гипераммониемии, что указывает на двунаправленную взаимосвязь между саркопенией и НАЖБП.</p></abstract><trans-abstract xml:lang="en"><p>Sarcopenia and non-alcoholic fatty liver disease (NAFLD) are common problems associated with aging. Despite the differences in diagnostic methods, a series of studies have appeared in recent years that have revealed a close relationship between sarcopenia and NAFLD. Sarcopenia and NAFLD are associated with a number of common pathogenetic mechanisms, which are discussed in the present article, including the role of insulin resistance at both the liver and muscle levels, hormonal imbalance, the role of systemic inflammation, dysregulation of myokines, vitamin D deficiency, the role of malnutrition and inactivity, the role of hepatokines and hyperammonemia, which indicates the bidirectional relationship between sarcopenia and NAFLD.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Саркопения</kwd><kwd>неалкогольная жировая болезнь печени</kwd><kwd>инсулинорезистентность</kwd><kwd>гепатокины</kwd><kwd>тестостерон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Sarcopenia</kwd><kwd>non-alcoholic fatty liver disease</kwd><kwd>insulin resistance</kwd><kwd>hepatokines</kwd><kwd>testosterone</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">Cruz-Jentoft AJ., Bahat G., Bauer J. et al.
