In clinical practice in the adult population, most cases of EPI are associated with chronic pancreatitis, while in the pediatric population – with cystic fibrosis. The regression of the production of digestive enzymes in EPI mediates the development of the syndrome of maldigestion and malabsorption, leading to the progressive development of malnutrition, the importance of which is often underestimated by practitioners. At the same time, the development of nutritional deficiency is not just a complication of EPI, but also has an important effect on the course of the underlying causative disease, worsening the prognosis and quality of life of the patient, and is also a proven risk factor for osteoporosis and sarcopenia. To date, compensation for the absolute deficiency of pancreatic enzymes using enzyme replacement therapy is the only possible way to correct the EPI and prevent nutritional deficiency.</p></abstract><trans-abstract xml:lang="ru"><p>Экзокринная недостаточность поджелудочной железы (ЭНПЖ) является частым осложнением как доброкачественных, так и злокачественных заболеваний поджелудочной железы, а также следствием радикальных хирургических операций на органе и целого спектра других вариативных внепанкреатических причин. В повседневной клинической практике во взрослой популяции большинство случаев ЭНПЖ ассоциировано с хроническим панкреатитом, тогда как в педиатрической популяции – с муковисцидозом. Регресс выработки пищеварительных ферментов при ЭНПЖ опосредует развитие синдрома мальдигестии и мальабсорбции, приводя к прогрессирующему развитию мальнутриции, значимость которой часто недооценивается практикующими специалистами. Вместе с тем развитие нутритивной недостаточности не просто является осложнением ЭНПЖ, но и оказывает важное влияние на течение основного причинного заболевания, ухудшая прогноз и качество жизни пациента, а также является доказанным фактором риска остеопороза и саркопении. На сегодняшний день компенсация абсолютного дефицита панкреатических ферментов с использованием заместительной ферментной терапии является единственно возможным путем коррекции ЭНПЖ и профилактики нутритивной недостаточности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>exocrine pancreatic insufficiency</kwd><kwd>chronic pancreatitis</kwd><kwd>cystic fibrosis</kwd><kwd>enzyme replacement therapy</kwd><kwd>malnutrition</kwd><kwd>maldigestion</kwd><kwd>malabsorption</kwd><kwd>nutritional status</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>экзокринная недостаточность поджелудочной железы</kwd><kwd>хронический панкреатит</kwd><kwd>муковисцидоз</kwd><kwd>заместительная ферментная терапия</kwd><kwd>мальнутриция</kwd><kwd>мальдигестия</kwd><kwd>мальабсорбция</kwd><kwd>нутритивный статус</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Diéguez-Castillo C, Jiménez-Luna C, Prados J, et al.
