Ntroduction. The article is devoted to the study of the features of the metabolic pathology of the liver under the influence of harmful industrial factors. The relevance of the study of nonalcoholic fatty liver disease of workers in contact with industrial aerosols is due to the high prevalence of the disease among the working-age population, the polyethological nature of the pathology, including the pathogenetic relationship with external household and occupational toxic effects. Materials and methods. The were examined two hundred four industrial production workers, divided into four groups according to the composition of the affected aerosol: copper-nickel ore dust, welding aerosol, quartz-containing dust, carbon-based dust. The survey was conducted using the AUDIT questionnaire, examination of patients, anthropometry, ultrasound examination of the abdominal organs, biochemical blood analysis, determination of viral hepatitis B and C markers, and serum immunoglobulins. Results. The frequency of detection of ultrasonic signs of liver damage in the examined patients who came into contact with copper-nickel aerosol dust significantly exceeds the same indicator of the studied patients who came into contact with quartz-containing dust (p<0.05) and also exceeds the frequency of detection in the group working under the influence of carbon-based and welding aerosol (p>0.05). Most often, an increase in the activity of liver enzymes was noted among those working in contact with copper-nickel ore dust. Significant differences were found between groups 1 and 3; 1 and 4 (p<0.05). There were no significant differences between the groups in the frequency of lipid and carbohydrate metabolism disorders and biliary tract pathology. Discussion. The results of the study may be related to the toxic effects of the copper-nickel aerosol but may also be associated with the climatogeographic features of the workers ‘ habitat. Conclusion. The prevalence of liver diseases in the group that came into contact with copper-nickel dust was established. The revealed changes do not depend on lipid and carbohydrate metabolism features, pathology of the biliary tract. For a detailed study of liver damage in industrial workers, it is necessary to conduct an in-depth study.

Nonalcoholic Fatty Liver

Nonalcoholic fatty liver disease (NAFLD) is independently linked to cardiometabolic morbidity and mortality. Low-grade inflammation, oxidative stress and ectopic fat, common features of chronic obstructive pulmonary disease (COPD), might contribute to the development of NAFLD.We aimed to investigate the prevalence of NAFLD and to evaluate the relationship between various types of liver damage and COPD severity, comorbidities and circulating inflammatory cytokines. Validated noninvasive tests (FibroMax: SteatoTest, NashTest and FibroTest) were used to assess steatosis, nonalcoholic steatohepatitis (NASH) and liver fibrosis. Patients underwent an objective assessment of COPD comorbidities, including sleep studies. Biological parameters included a complete lipid profile and inflammatory markers.In COPD patients the prevalence of steatosis, NASH and fibrosis were 41.4%, 36.9% and 61.3%, respectively. In multivariate analysis, SteatoTest and FibroTest were significantly associated with sex, body mass index (BMI), untreated sleep apnoea and insulin resistance, and, in addition, COPD Global Initiative for Chronic Obstructive Lung Disease stage for SteatoTest. Patients with steatosis had higher tumour necrosis factor-α levels and those with NASH or a combination of liver damage types had raised leptin levels after adjustment for age, sex and BMI.We concluded that NAFLD is highly prevalent in COPD and might contribute to cardiometabolic comorbidities.

Doxorubicin (DOX) is a successful chemotherapeutic widely used for the treatment of a range of cancers. However, DOX can have serious side-effects, with cardiotoxicity and hepatotoxicity being the most common events. Oxidative stress and changes in metabolism and bioenergetics are thought to be at the core of these toxicities. We have previously shown in a clinically-relevant rat model that a low DOX dose of 2 mg kg–1 week–1 for 6 weeks does not lead to cardiac functional decline or changes in cardiac carbohydrate metabolism, assessed with hyperpolarized [1-13C]pyruvate magnetic resonance spectroscopy (MRS). We now set out to assess whether there are any signs of liver damage or altered liver metabolism using this subclinical model. We found no increase in plasma alanine aminotransferase (ALT) activity, a measure of liver damage, following DOX treatment in rats at any time point. We also saw no changes in liver carbohydrate metabolism, using hyperpolarized [1-13C]pyruvate MRS. However, using metabolomic analysis of liver metabolite extracts at the final time point, we found an increase in most acyl-carnitine species as well as increases in high energy phosphates, citrate and markers of oxidative stress. This may indicate early signs of steatohepatitis, with increased and decompensated fatty acid uptake and oxidation, leading to oxidative stress.

Nonalcoholic Fatty Liver

Nonalcoholic fatty liver disease (NAFLD) encompasses a wide spectrum of liver damage from the more prevalent (75%–80%) and nonprogressive nonalcoholic fatty liver (NAFL) category to its less common and more ominous subset, nonalcoholic steatohepatitis (NASH). NAFLD is now the most common cause of chronic liver disease in the developed world and is a leading indication for liver transplantation in United States (US). The global prevalence of NAFLD is estimated to be 25%, with the lowest prevalence in Africa (13.5%) and highest in the Middle East (31.8%) and South America (30.4%). The increasing incidence of NAFLD has been associated with the global obesity epidemic and manifestation of metabolic complications, including hypertension, diabetes, and dyslipidemia. The rapidly rising healthcare and economic burdens of NAFLD warrant institution of preventative and treatment measures in the high-risk sub-populations in an effort to reduce the morbidity and mortality associated with NAFLD. Genetic, demographic, clinical, and environmental factors may play a role in the pathogenesis of NAFLD. While NAFLD has been linked with various genetic variants, including PNPLA-3, TM6SF2, and FDFT1, environmental factors may predispose individuals to NAFLD as well. NAFLD is more common in older age groups and in men. With regards to ethnicity, in the US, Hispanics have the highest prevalence of NAFLD, followed by Caucasians and then African-Americans. NAFLD is frequently associated with the components of metabolic syndrome, such as type 2 diabetes mellitus (T2DM), obesity, hypertension, and dyslipidemia. Several studies have shown that the adoption of a healthy lifestyle, weight loss, and pro-active management of individual components of metabolic syndrome can help to prevent, retard or reverse NAFLD-related liver damage. Independently, NAFLD increases the risk of premature cardiovascular disease and associated mortality. For this reason, a case can be made for screening of NAFLD to facilitate early diagnosis and to prevent the hepatic and extra-hepatic complications in high risk sub-populations with morbid obesity, diabetes, and other metabolic risk factors.
