Redox Homeostasis and Non-Invasive Assessment of Significant Liver Fibrosis by Shear Wave Elastography.

Hepatic fibrosis with various origins can be estimated non-invasively by using certain biomarkers and imaging-based measurements. The aim of our study was to examine redox homeostasis biomarkers and liver stiffness measurements for the assessment of significant liver fibrosis in different etiologies of chronic liver diseases. A cohort study consisting of 88 chronic liver disease patients of both sexes (age 49.

[The significance of omega-3 fatty acids in the treatment of non-alcoholic fatty liver disease].

Today, non-alcoholic fatty liver disease is the most common chronic liver disease, yet there is no clearly accepted effective therapy. What is certain is that the number of people suffering from the disease is increasing, making prevention, treatment and recognition of co-morbidities of paramount importance. Current evidence suggests that the development of non-alcoholic fatty liver disease may be due to pathological factors of different origins.

Metronidazole does not show direct antioxidant activity in global systems.

Metronidazole has been widely used topically and systemically for more than 50 years but data on its antioxidant properties are still incomplete, unclear and contradictory. Its antioxidant properties are primarily hypothesized based on results, therefore, studies have been performed to determine whether metronidazole has antioxidant activity . We used so-called global spectrophotometric and luminometric methods.

Impact of milk thistle (Silybum marianum) on the mycotoxin caused redox-homeostasis imbalance of ducks liver.

The Fusarium mycotoxins deoxynivalenol (DON) and zearalenone (ZEA) frequently contaminate grain crops, especially maize, the basis of poultry's feed. Mycotoxins enter the food chain and induce pathological changes in edible tissues. Milk thistle (Silybum marianum) has been used for the treatment of liver disease in humans because of its antioxidant and hepatoprotective effects, but its utility in veterinary use is poorly examined.

[The potential role of organic and conventional yoghurt consumption in the treatment of non-alcoholic fatty liver disease].

Introduction: Health is an important motivation for the consumption of both organic and functional foods. Organic food contains fewer pesticide residues and statistically more selected health-related compounds such as polyphenols in plant products and polyunsaturated fatty acids in milk and meat products. Recent studies suggest that the gut-liver axis plays an important role in the pathogenesis of non-alcoholic fatty liver disease, so probiotics could be a therapeutic tool.

[Factors affecting liver disease progression, with emphasis on the role of free radical reactions].

Chronic liver disorders are the main leading cause of morbidity and mortality data. Viral infection, toxic injury, metabolic, autoimmun, storage disorders, in the case of ongoing presence of the etiological factors, could result in fibrotic remodelling in the liver. The process is complex, not fully understood in details; cells, cytokines, chemokines release, altered secretion of hepatokines, lipotoxicity, innate immun system, gut microbiom, metal ions and free radical reactions all have a role in it.

[Changes in endogenous metal element concentrations in various aetiologies of chronic liver disease].

Our body contains physiologically many metal ions used for its metabolic processes and function. Metal ion changes can start pathological processes, however, the pathological processes may also lead to changes in metal ion concentration. In this study, the authors summarize the physiologically present metal ions' change in liver diseases with various aetiologies, the consequences are discussed as well as the connections with the progression.

[Hepatitis C virus infection and hepatocarcinogenesis].

Hepatitis C virus infection causes approximately 4 million new infections worldwide, and 399 000 deaths due to its complications, cirrhosis and hepatocellular carcinoma (HCC). Microenvironmental changes, chronic inflammation, oxidative stress, endoplasmic reticulum stress caused by HCV infection, genetic and epigenetic changes can result in primary liver cancer during decades. The direct oncogenic property of HCV is wellknown.

[The role of gut microbiota in chronic liver diseases, and treatment possibilities].

The community of microorganisms in the intestine, namely gut microbiome lives in symbiosis with the host, contributing to its homeostasis and influencing it simultaneously. It can be suspected that gut microbiome plays a central role in the pathophysiology of intestinal and extraintestinal diseases: determining their development, progress and complications. Recently, intestinal microbiome has become a highlighted field of interest and important topic in research, especially in hepatology.

Metal- and redox homeostasis in prostate cancer with vitamin D supplementation.

Vitamin D supplementation has a beneficial effect on cancerous patients, although it can influence the redox- and metal homeostasis. The aim of our investigation was to demonstrate the effect of vitamin D consumption on the redox- and metal homeostasis in prostate cancer, because of the recommended daily dose increased from 200 IU to 2000 IU in recent years in Hungary. Forty-three volunteers were involved in the study.

[Gut-liver axis in inflammatory bowel disease. A retrospective study].

Introduction: Examination of the gut-liver axis came into the spotlight worldwide. Liver enzyme elevations are commonly seen in patients with inflammatory bowel disease (IBD), which is a diagnostic challenge in everyday clinical practice. Liver and biliary diseases are common extra-intestinal manifestations in Crohn's disease and ulcerative colitis.

[Extrahepatic manifestations in chronic hepatitis C infected patients].

The importance of chronic hepatitis C infection is significant. 3% of the World's population is infected. There is at least one extrahepatic manifestation in 50% of HCV patients, which makes the prognosis and mortality worse.

[Various pathways leading to the progression of chronic liver diseases].

As the result of various effects (viruses, metabolic diseases, nutritional factors, toxic agents, autoimmune processes) abnormal liver function, liver steatosis and connective tissue remodeling may develop. Progression of this process is complex including various pathways and a number of factors. The authors summarize the factors involved in the progression of chronic liver disease.

[Antioxidants--antioxidative stress: facts and questions, 2015].

In the past years great importance has been attributed to antioxidant therapy in the prevention and treatment of disorders developed in connection with oxidative stress. After initial success, undesirable effects, toxicities, and prooxidant effects of antioxidants were reported [CARET, ATBC study]. In addition, metaanalyses failed to confirm the role of antioxidant supplementation in the primary and secondary prevention.

[Non-invasive assessment of fatty liver].

As the result of various harmful effects (infectious agents, metabolic diseases, unhealthy diet, obesity, toxic agents, autoimmune processes) hepatic damage may develop, which can progress towards liver steatosis, and fibrosis as well. The most common etiological factors of liver damages are hepatitis B and C infection, alcohol consumption and non-alcoholic fatty liver disease. Liver biopsy is considered as the gold standard for the diagnosis of chronic liver diseases.

[Options for non-invasive assessment of liver fibrosis based on clinical data].

Liver cirrhosis is one of the leading causes of death worldwide. Liver biopsy is considered as the gold standard for the diagnosis of chronic liver diseases. Studies have focused on non-invasive markers for liver fibrosis because of the dangers and complications of liver biopsy.
