Неалкогольная жировая болезнь печени в большинстве случаев тесно ассоциирована с такими заболеваниями, как ожирение и сахарный диабет 2 типа, однако у ряда пациентов не наблюдается данной зависимости. В этом случае наибольшую ценность для прогноза течения заболевания приобретают наследственные факторы, такие как вариант p.I148M гена PNPLA3.</p><p>Цель – оценка ассоциации варианта p.I148M гена PNPLA3 с отягощенным течением НАЖБП у подгрупп пациентов с наличием и отсутствием сопутствующей метаболической патологии.</p></sec><sec><title>Методы и материалы</title><p>Методы и материалы. В исследуемую группу вошли 212 пациентов с НАЖБП, которым было проведено генотипирование p.I148M гена PNPLA3. Тяжесть заболевания оценивали в общей группе (группа П) и в подгруппах пациентов с отсутствием и наличием ожирения (подгруппы О– и О+ соответственно) и сахарного диабета 2 типа (подгруппы Д– и Д+). Тяжесть заболевания оценивалась по степени выраженности цитолитического синдрома (уровень АЛТ), стеатоза и фиброза печени (значение КПЗУ и жесткости печени по данным транзиентной эластометрии) внутри клинических подгрупп между носителями различных генотипов PNPLA3.</p></sec><sec><title>Результаты</title><p>Результаты. Более высокие значения АЛТ были обнаружены у гомозиготных носителей p.I148M по сравнению с референтным генотипом (CC/GG) в подгруппах П, Д–, Д+ и О– (p=0,012; p=0,012; p=0,028 и 0,042 соответственно), а также при сравнении общей группы носителей с референтным генотипом (CC/CG+GG) в подгруппах П и Д– (p=0,036 и p=0,015). Более выраженный стеатоз был обнаружен у гомозиготных носителей по сравнению с референтным генотипом (CC/GG) в группе П (p=0,017) и подгруппе О– (p=0,019). Более высокие значения жесткости печени были отмечены у измененного генотипа PNPLA3 при сравнении референтного (CC/CG) генотипа с гетерозиготами в группе П (p=0,027) и подгруппе Д– (p=0,006) и при сравнении референтного генотипа с общей группой носителей (CC/CG+GG) в подгруппе Д– (p=0,009).</p></sec><sec><title>Выводы</title><p>Выводы. Носительство p.I148M гена PNPLA3 у пациентов без метаболических нарушений (ожирение, сахарный диабет 2 типа) ассоциировано с формированием цитолитического синдрома, стеатоза и фиброза печени.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Non-alcoholic fatty liver disease in most cases is closely associated with diseases such as obesity and type 2 diabetes mellitus, however, this dependence is not observed in a number of patients. In this case, hereditary factors, such as the p.I148M polymorphism of the PNPLA3 gene, play the greatest role in the prognosis of the course of the disease.</p><p>The objective of the study was to evaluate the effect of the p.I148M polymorphism of the PNPLA3 gene on the course of NAFLD in subgroups of patients with and without concomitant metabolic pathology.</p></sec><sec><title>Methods and materials</title><p>Methods and materials. The study group included 212 patients with NAFLD who underwent p.I148M genotyping of the PNPLA3 gene. The severity of the disease was assessed in the general group (group P) and in subgroups of patients with the absence and presence of obesity (subgroups O– and O+, respectively) and type 2 diabetes mellitus (subgroups D– and D+). The severity of the disease was assessed by the severity of cytolytic syndrome (ALT level), hepatic steatosis and fibrosis (the value of CAP and liver stiffness according to transient elastometry) within clinical subgroups between carriers of different PNPLA3 genotypes.</p></sec><sec><title>Results</title><p>Results. Higher ALT levels were found in homozygous carriers of p.I148M compared with the reference genotype (CC/GG) in the subgroups P, D–, D+ and O– (p=0.012; p=0.012; p=0.028 and 0.042, respectively), as well as when comparing the general group of carriers with reference genotype (CC/CG+GG) in subgroups P and D– (p=0.036 and p=0.015). More severe steatosis was found in homozygous carriers compared to the reference genotype (CC/GG) in group P (p=0.017) and subgroup O– (p=0.019). Higher values of liver stiffness were noted in the modified PNPLA3 genotype when comparing the reference (CC/CG) genotype with heterozygotes in group P (p=0.027) and subgroup D– (p=0.006) and when comparing the reference genotype with the general carrier group (CC/CG+GG) in subgroup D– (p=0.009).</p></sec><sec><title>Conclusions</title><p>Conclusions. The carriage of p.I148M of the PNPLA3 gene in patients without metabolic disorders (obesity, type 2 diabetes mellitus) is associated with the formation of cytolytic syndrome, steatosis and liver fibrosis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>неалкогольная жировая болезнь печени</kwd><kwd>НАЖБП</kwd><kwd>ген PNPLA3</kwd><kwd>стеатоз печени</kwd><kwd>фиброз печени</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nonalcoholic fatty liver disease</kwd><kwd>NAFLD</kwd><kwd>PNPLA3 gene</kwd><kwd>liver steatosis</kwd><kwd>liver fibrosis</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">Younossi Z.
