During the progression from hepatitis to fibrosis, cirrhosis, and liver failure, the accumulation of stressed/damaged hepatocyte elements associated with liver inflammation is critical. The causes of hepatocyte injuries include viral hepatitis infections, alcoholic hepatitis, and non-alcoholic fatty liver disease. Hepatocyte-derived extracellular vesicles (Hep-EVs) released from stressed/damaged hepatocytes are partly responsible for liver disease progression and liver damage because they activate non-parenchymal cells and infiltrate inflammatory cells within the liver, which are in turn are an important source of EVs. This cell-to-cell signaling is prevalent during inflammation in many liver diseases. Accordingly, special emphasis should be placed on liquid biopsy methods for the long-term monitoring of chronic liver diseases. In the present review, we have highlighted various aspects of current liquid biopsy research into chronic liver diseases. We have also reviewed recent progress on liquid biopsies that focus on cell-free DNA (cfDNA), long non-coding RNA (lncRNA), and the proteins in EVs as potential diagnostic tools and novel therapeutic targets in patients with viral hepatitis, fatty liver steatosis, and alcoholic liver diseases.

The Impact

Chronic viral hepatitis B and C and non-alcoholic fatty liver disease (NAFLD) have been widely acknowledged to be the leading causes of liver cirrhosis and hepatocellular carcinoma. As anti-viral treatment progresses, the impact of NAFLD is increasing. NAFLD can coexist with chronic viral hepatitis and exacerbate its progression. Oxidative stress has been recognized as a chronic liver disease progression-related and cancer-initiating stress response. However, there are still many unresolved issues concerning oxidative stress, such as the correlation between the natural history of the disease and promising treatment protocols. Recent findings indicate that oxidative stress is also an anti-cancer response that is necessary to kill cancer cells. Oxidative stress might therefore be a cancer-initiating response that should be down regulated in the pre-cancerous stage in patients with risk factors for cancer, while it is an anti-cancer cell response that should not be down regulated in the post-cancerous stage, especially in patients using anti-cancer agents. Antioxidant nutrients should be administered carefully according to the patients’ disease status. In this review, we will highlight these paradoxical effects of oxidative stress in chronic liver diseases, pre- and post-carcinogenesis.

The aim of the study was to identify the prevalence ofHFEgene mutations in Czech patients with chronic liver diseases and the influence of the mutations on iron status. The presence ofHFEgene mutations (C282Y, H63D, and S65C) analyzed by the PCR-RFLP method, presence of cirrhosis, and serum iron indices were compared among 454 patients with different chronic liver diseases (51 with chronic hepatitis B, 122 with chronic hepatitis C, 218 with alcoholic liver disease, and 63 patients with hemochromatosis). Chronic liver diseases patients other than hemochromatics did not have an increased frequency ofHFEgene mutations compared to controls. Although 33.3% of patients with hepatitis B, 43% of patients with hepatitis C, and 73.2% of patients with alcoholic liver disease had elevated transferrin saturation or serum ferritin levels, the presence ofHFEgene mutations was not significantly associated with iron overload in these patients. Additionally, patients with cirrhosis did not have frequencies ofHFEmutations different from those without cirrhosis. This study emphasizes the importance, not only of C282Y, but also of the H63D homozygous genetic constellation in Czech hemochromatosis patients. Our findings show that increased iron indices are common in chronic liver diseases butHFEmutations do not play an important role in the pathogenesis of chronic hepatitis B, chronic hepatitis C, and alcoholic liver disease.

Liver fibrosis represents the repair mechanism in liver injury and is a feature of most chronic liver diseases. The degree of liver fibrosis in chronic viral hepatitis infection has major clinical implications and presence of advanced fibrosis or cirrhosis determines prognosis. Treatment initiation for viral hepatitis is indicated in most cases of advanced liver fibrosis and diagnosis of cirrhosis entails hepatology evaluation for specialized clinical care. Liver biopsy is an invasive technique and has been the standard of care of fibrosis assessment for years; however, it has several limitations and procedure related complications. Recently, several methods of noninvasive assessment of liver fibrosis have been developed which require either serologic testing or imaging of liver. Imaging based noninvasive techniques are reviewed here and their clinical use is described. Some of the imaging based tests are becoming widely available, and collectively they are shown to be superior to liver biopsy in important aspects. Clinical utilization of these methods requires understanding of performance and quality related parameters which can affect the results and provide wrong assessment of the extent of liver fibrosis. Familiarity with the strengths and weakness of each modality is needed to correctly interpret the results in appropriate clinical content. A new technique called Elast PQ uses ultrasound shear wave elastography to provide a noninvasive, reproducible, easily performed method of assessing liver fibrosis. It can easily combine a routine ultrasound imaging exam of the liver anatomy with targeted tissue stiffness values, assess liver fibrosis in patient with clinically suspected disease even before abnormalities are detected with ultrasound imaging, evaluate and obtain a baseline stiffness value in patients with chronic liver disease, follow up patients under treatment to monitor progression, stabilization or regression of liver disease and help avoid the need for liver biopsies when elastography results are consistent with other clinical findings. Both the prognosis and potential treatment of chronic liver diseases greatly depend on the progression of liver fibrosis, which is the ultimate outcome of chronic liver damage. Historically, liver biopsy has been instrumental in adequately assessing patients allows clinicians both to obtain diagnosis information and initiate adequate therapy. However, the technique is not exempt of deleterious effects. Multiple diagnostic tests have been developed for the staging of fibrosis using noninvasive methods, most of them in the setting of chronic hepatitis C. The goal of this paper is to review available data on the staging and assessment of liver fibrosis with two methods: serum markers & transient elastography (FibroScan).Faridpur Med. Coll. J.

Liver cirrhosis is one of the most prevalent chronic liver diseases worldwide. In addition to viral hepatitis, diseases such as steatohepatitis, autoimmune hepatitis, sclerosing cholangitis and Wilson’s disease can also lead to cirrhosis. Moreover, alcohol can cause cirrhosis on its own and exacerbate chronic liver disease of other causes. The treatment of cirrhosis can be divided into addressing the cause of cirrhosis and reversing liver fibrosis. To this date, there is still no clear consensus on the treatment of cirrhosis. Recently, there has been a lot of interest in potential treatments that modulate the gut microbiota and gut-liver axis for the treatment of cirrhosis. According to recent studies, modulation of the gut microbiome by probiotics ameliorates the progression of liver disease. The precise mechanism for relieving cirrhosis via gut microbial modulation has not been identified. This paper summarizes the role and effects of the gut microbiome in cirrhosis based on experimental and clinical studies on absorbable antibiotics, probiotics, prebiotics, and synbiotics. Moreover, it provides evidence of a relationship between the gut microbiome and liver fibrosis.

Asthenia and fatigue are the most common syndromes in patients with liver disease, which significantly affects their quality of life. The prevalence of fatigue in chronic liver diseases is from 50% to 85%. While some progress has been made in understanding the processes that can cause fatigue in general, the underlying causes of fatigue associated with liver disease remain not well understood. In particular, many data suggest that fatigue associated with liver disease likely results from changes in neurotransmission in the brain against the background of hyperammonemia. Hyperammonemia is a metabolic state characterized by an increased level of  ammonia, a  nitrogen-containing compound. The  present review describes hyperammonemia, which is likely important in the pathogenesis of fatigue associated with liver disease. Ammonia is a potent neurotoxin, its elevated blood levels can cause neurological signs and symptoms that can be acute or chronic, depending on the  underlying pathology. Hyperammonemia should be recognized early, and immediately treated to prevent the development of life-threatening complications, such as, swelling of the brain and coma. The article gives pathophysiological mechanisms of influence of hyperammonemia on state of psychovegetative status of patients with liver diseases, also lists basic principles of treatment. A significant part of the article is devoted to L-ornithine-L-aspartate, which is effective in asthenia and fatigue to reduce the level of hyperammonemia through a variety of well-studied mechanisms in chronic liver diseases.

The pandemic of the new coronavirus COVID-19 has switched medicine around the world on the primary fight against this infection. Patients with chronic liver diseases require increased attention of doctors during an epidemic, since against the background of an exacerbation of their disease, not only the risk of contracting the COVID 19 viral infection increases, but also its more severe course. Patients with confirmed COVID-19 with severe liver damage - high biochemical activity. According to some reports, patients with a severe course of COVID-19 have an increase in ALT levels, a decrease in the number of platelets, a decrease in the level of albumin, and a connection (although not all indicators) with a higher risk of mortality is possible.
