Системный амилоидоз, вызванный образованием и отложением легких цепей иммуноглобулинов (ALамилоидоз), представляет собой относительно редкое заболевание с поражением сердца, почек, периферической нервной системы, желудочно-кишечного тракта, что обуславливает многообразие его клинических проявлений. Мы представляем случай системного AL-амилоидоза с преимущественным поражением печени, желудка, кишечника и сердца без вовлечения почек у женщины европеоидной расы.</p></sec><sec><title>Основное содержание</title><p>Основное содержание. Пациентка предъявляла жалобы на выраженную общую слабость, боль в животе, диарею, быструю потерю массы тела и сердцебиение. Эзофагогастродуоденоскопия выявила кровоточащую язву двенадцатиперстной кишки и ретробульбарный полипоз. Содержание гемоглобина было снижено, а уровни щелочной фосфатазы, гамма-глутамилтранспептидазы и N-терминального предшественника мозгового натрийуретического пептида были повышены. Также имелись признаки сердечной недостаточности с сохраненной фракцией выброса и гепатомегалия. Была проведена биопсия печени, желудка и двенадцатиперстной кишки. Гистохимическое и иммуногистохимическое исследование биоптатов подтвердило диагноз AL-амилоидоза. Проведено лечение мелфаланом и дексаметазоном с удовлетворительным эффектом.</p></sec><sec><title>Заключение</title><p>Заключение. Тщательное клиническое обследование пациента вместе с патоморфологическим и иммуногистохимическим исследованиями биоптатов позволили установить верный диагноз и назначить адекватную терапию, что улучшило состояние пациента. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. Systemic amyloidosis caused by the synthesis and deposition of immunoglobulin light chains (AL amyloidosis) is a relatively rare disease that involves heart, kidneys, peripheral nervous system, gastrointestinal tract, and has a large number of various clinical manifestations. We present a clinical case of systemic AL amyloidosis with a predominant involvement of liver, stomach, intestines, and heart in a Caucasian female.</p></sec><sec><title>Key points</title><p>Key points. A Caucasian woman presented to clinic with severe general weakness, abdominal pain, diarrhea, sudden weight loss, and palpitation. Initial examination revealed a duodenal bulb ulcer complicated by bleeding and polyps in the retrobulbar part of duodenum. Decreased hemoglobin levels, elevated levels of alkaline phosphatase, gamma-glutamyltransferase, and N-terminal prohormone of brain natriuretic peptide, signs of heart failure with preserved ejection fraction, and hepatomegaly became the basis for a clinical suspicion of AL amyloidosis and puncture liver biopsy. Histochemical and immunohistochemical studies of liver, stomach, and duodenum biopsy specimens confirmed AL amyloidosis. Timely diagnosis made it possible to conduct a specific therapy with melphalan plus dexamethasone, get a satisfactory response and improve the patient’s condition.</p></sec><sec><title>Conclusion</title><p>Conclusion. A thorough examination of patients along with a pathomorphological and immunohistochemical study of the biopsy specimens is the basis for confirming the diagnosis of AL amyloidosis, selecting the proper therapy, improving the condition of patients and their survival. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>первичный AL амилоидоз</kwd><kwd>амилоидоз легких цепей иммуноглобулинов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary AL amyloidosis</kwd><kwd>immunoglobulin light chain amyloidosis</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">Benson M.D., Buxbaum J.N., Eisenberg D.S., Merlini G., Saraiva M.J.M., Sekijima Y., et al.
