Клиническими проявлениями этой патологии является бронхиальная астма (БА) с фиксированной обструкцией, панацинарная эмфизема или бронхоэктазы, а также поражение печени. Выделяют несколько типов аллелей гена SERPINA1: нормальные PiMM, дефицитные (с недостаточным поступлением А1АТ из печени в кровь из-за полимеризации) PiSS и PiZZ, нулевые (с полным отсутствием А1АТ в крови) PiNulNul, аллели с нормальным количеством, но нарушением функции А1АТ, например Pittsburgh.</p><p>Целью работы являлась демонстрация течения дефицита А1АТ у пациента с дебютом в возрасте 40 лет. Особенностью течения заболевания у данного пациента является также отсутствие поражения печени, а такое поражение обычно является частым проявлением дефицита А1АТ в случае мутации с аллелем Pi*ZZ. У пациента инициирована патогенетическая терапия ингибитором α1-протеиназы, на фоне которой у больного в настоящий момент наблюдается стабилизация клинической симптоматики.</p><p>Заключение. Важно информировать врачей разных специальностей о дефиците А1АТ для ускорения начала необходимой патогенетической терапии, которая поможет улучшить состояние пациента и предотвратить развитие тяжелых осложнений.</p></abstract><trans-abstract xml:lang="en"><p>Alpha-1-antitrypsin (А1АТ) deficiency is a genetically determined disease caused by a mutation in the SERPINA1 (serpin peptidase inhibitor, clade A) gene responsible for А1АТ synthesis. The clinical manifestations are bronchial asthma with fixed obstruction, panacinar emphysema or bronchiectasis, and liver damage. There are several types of SERPINA1 gene alleles: normal PiMM, deficient (with insufficient А1АТ secretion from the liver into the blood due to polymerization) PiSS and PiZZ, null (with complete absence of A1AT in the blood) PiNulNul, alleles with normal amount but impaired function of А1АТ, such as Pittsburgh.</p><p>The aim of our work was to demonstrate the course of А1АТ deficiency in a patient at the age of 40. The peculiarity of the course of the disease in our patient is also the absence of liver damage, and such damage is usually a frequent manifestation of α 1-antitrypsin deficiency in the case of a mutation with the Pi*ZZ allele. Causative therapy with an α1-proteinase inhibitor was initiated and the patient’s clinical symptoms stabilized.</p><p>Conclusion. It is important to inform physicians of various specialties about А1АТ deficiency in order to accelerate the initiation of necessary causative therapy, which helps improve the patient’s condition and prevent the development of severe complications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>альфа-1-антитрипсин</kwd><kwd>бронхиальная обструкция</kwd><kwd>SERPINA1</kwd><kwd>ингибитор протеазы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alpha-1-antitrypsin</kwd><kwd>bronchial obstruction</kwd><kwd>SERPINA1</kwd><kwd>protease inhibitor</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">Министерство здравоохранения Российской Федерации.
