ЦЕЛЬ Обзора — представить наиболее интересные и активно обсуждаемые результаты исследований в области эпидемиологии, клиники и лечения неалкогольной жировой болезни печени. Освещена новая концепция понимания болезни как метаболически-ассоциированной жировой болезни печени, проанализированы современные подходы к ее диагностике. Рассмотрены потенциальные мишени терапевтического воздействия для редукции стеатоза и фиброза при этой патологии. Отмечено, что, в отличие от эпидемиологических и фундаментальных исследований, клинические аспекты заболевания и терапевтические подходы находятся в процессе поиска и разработки.

The association of non-alcoholic fatty liver disease (NAFLD) and cardiovascular risk is currently one of the actively studied areas. The incidence of non-alcoholic fatty liver disease continues to grow worldwide. In the structure of mortality rate of patients with non-alcoholic fatty liver disease, the first place is occupied by cardiovascular events: stroke and myocardial infarction. Studies have shown that the presence of severe liver fibrosis (F3-4) in NAFLD not only increases the risk of cardiovascular diseases (CVD), but also increases the risk of overall mortality by 69% due to mortality from cardiovascular causes. The degree of increased risk is associated with the degree of activity of non-alcoholic steatohepatitis (NASH). Despite the large number of works on this topic, we do not have a clear opinion on the impact on cardiovascular risk, interaction and the contribution of various factors, as well as algorithms for managing patients with non-alcoholic fatty liver disease to reduce the risk of cardiovascular diseases. This article describes the pathogenetic factors of formation of cardiovascular risks in patients with non-alcoholic fatty liver disease, proposed the idea of stratification of cardiovascular risks in these patients, taking into account changes in the structure of the liver (fibrosis) and function (clinical and biochemical activity) and also it describes the main directions of drug therapy, taking into account the common pathogenetic mechanisms for non-alcoholic fatty liver disease and cardiovascular diseases. The role of obesity, local fat depots, adipokines, and endothelial dysfunction as the leading pathogenetic factors of increased cardiovascular risk in patients with NAFLD is discussed. Among pathogenetically justified drugs in conditions of poly and comorbidity, hypolipidemic (statins, fibrates), angiotensin II receptor antagonists, beta-blockers, etc. can be considered. According to numerous studies, it becomes obvious that the assessment of cardiovascular risks in patients with NAFLD will probably allow prescribing cardiological drugs, selecting individualized therapy regimens, taking into account the form of NAFLD, and on the other hand, building curation taking into account the identified cardiovascular risks.

Aim. To estimate the diagnostic and informative value of clinical and laboratory parameters in the development and progression of liver fibrosis in patients with nonalcoholic fatty liver disease (NAFLD) to enhance efficiency of their treatment. Subjects and methods. An open-label case-control study included 77 patients with NAFLD. Clinical and laboratory examinations were done. To search for additional noninvasive fibrosis markers, the investigators studied the serum concentrations of insulin, leptin, adiponectin, matrix metalloproteinase-9 (MMP-9) and its inhibitors, such as tissue inhibitor of matrix metalloproteinases 1 (TIMP-1) and TIMP-2. All the patients underwent elastometry to assess the degree of liver fibrosis with the Metavir scale with the use of a Fibroscan machine. Results. The serum levels of low-density lipoproteins, glucose, MMP-9, and leptin proved to be most informative in assessing the progression of the initial stages (1-2) of fibrosis, as were the increased liver size detected by physical examination, systolic blood pressure, carbohydrate metabolic disorders, alanine/aspartate aminotransferase levels, waist-to-hip ratio, TIMP-1, and TIMP-2 in evaluating the progression of Stage II fibrosis 2 to Stage 3. Conclusion. The clinical and laboratory parameters can serve as reliable noninvasive markers that reflect the progression of fibrotic changes in liver tissue.

В статье представлено 4 клинических случая аутоиммунного гастрита. Мы рассмотрели клинические и лабораторно-инструментальные данные с целью определения ключевых показателей, характерных для данного заболевания. Обсуждены ведущие симптомы, принципы диагностики и лече-ния аутоиммунного гастрита. «Золотым стандартом» диагностики аутоиммунного гастрита остается эзофагогастродуоденоскопия с биопсией по OLGA-system, позволяющая определить не только стадию и степень атрофии слизистой оболочки желудка, но и наличие предраковых изменений, требующих постоянного динамического наблюдения за пациентом. Наиболее важным для постановки диагноза является обнаружение при морфо-логическом исследовании признаков метапластической и неметапластической атрофии желез преимущественно тела желудка наряду с гиперпла-зией нейроэндокринных клеток. Подтвердить диагноз также помогает серологическая диагностика для определения аутоантител класса иммуно -глобулина G к париетальным клеткам и внутреннему фактору Кастла. Ключевые слова: аутоиммунный гастрит, клинические случаи, атрофия слизистой оболочки желудка, гиперплазия нейроэндокринных клеток, ан-титела к париетальным клеткам.
