The prevalence of metabolic dysfunction-associated fatty liver disease (MAFLD) is increasing rapidly worldwide due to the obesity epidemic. Advanced stages of the MAFLD, such as non-alcoholic steatohepatitis (NASH) with advanced fibrosis or cirrhosis are affecting global health. Extracellular vesicles (EVs) are released by all cell types and are important in cell-to-cell communication and maintaining homeostasis, but they also play a role in the pathogenesis of various diseases. EVs contain biological information such as lipids, proteins, messenger RNAs (mRNAs), small RNAs, and DNA, and they act on (distant) target cells. The cargo of EVs is dependent on the type and the state of the releasing cell. EVs have been proposed as biomarkers, prognostic, and even therapeutic agents, also in the context of liver diseases. This review aims to give an overview of the current knowledge on EVs in MAFLD, including the role and interaction of EVs with different cell types in the liver. Several aspects of EVs, including their origin, characteristics, cargo, and functions are reviewed. Moreover, the potential of EVs as targets for the treatment of MAFLD is discussed.

Hepatocellular carcinoma (HCC) is considered one of the most aggressive tumors worldwide. The consumption of lipid-enriched diets, mainly high cholesterol, induces oxidative stress and chronic inflammation, leading to HCC progression. Moreover, fatty acids and cholesterol could display differential responses on immune cells inside the tumor immune microenvironment (TIME). Tumor-associated macrophages (TAMs) represent one of the most critical leukocytes in the tumor microenvironment (TME) displaying pro-tumoral responses and one of the mainly cholesterol donors to cancer cells. Immunotherapy or cholesterol regulators, alone or combined, would represent an effective strategy for HCC treatment. Nonetheless, steatotic etiology from non-alcoholic fatty liver disease (NAFLD)-HCC tumors has been unexpectedly resulting in highly aggressive behavior.

Aim:

Cholestasis remains a partially characterized disease. Evidence has been gained that it is a systemic disease that begins in the liver but significantly impacts other organs and systems such as the kidney, heart, and intestine, among others. One of the primary damage mechanisms is the generation of reactive oxygen species (ROS), which eventually leads to oxidative stress, impacting canalicular morphology and actin cytoskeleton changes that could worsen the problem. These characteristics are also observed in the kidney and intestine. The work focused on addressing the intestine effects of intrahepatic cholestasis induced by α-naphthyl isothiocyanate (ANIT) and the protective response of the hepatocyte growth factor (HGF).

Methods:

The 10- to 12-week-old CD1 male mice were treated with ANIT and then treated or not with HGF; intestine damage was addressed by histology, immunohistochemistry (IHC) of specific markers, oxidative stress, and apoptosis.

Results:

Results show changes in the intestine histology, particularly the colon and ileum, induced by the cholestasis. HGF treatment restored the histology presentation and reverted the oxidative damage, clearly indicating a healing response. This observation was supported by an increment in anti-inflammatory macrophages (CD163+) in the HGF treatment.

Conclusions:

The data prove that HGF induces a protective and repairing response in the intestine under cholestatic challenges.

Worldwide the number of individuals being overweight or obese has dramatically increased during the last decades, which is also associated with a similar dramatic increase of individuals afflicted with metabolic disorders like dyslipidemia, hypertension, and non-alcoholic fatty liver disease (NAFLD). Genetic predisposition may account for some of the increases in body weight and the development of metabolic disorders; however, much is probably also related to the changes in physical activity and dietary pattern. Indeed, results of epidemiological studies suggest that a ‘western-type dietary pattern’ composed of highly processed foods, sweetened foods, and beverages, all adding to a low fiber but high sugar and saturated fat intake, may increase the odd of developing overweight and metabolic disorders. Consumption of sugar, and especially, fructose has repeatedly been discussed to be a key contributor to the development of health disturbances including hypertension, dyslipidemia, insulin resistance as well as NAFLD. However, despite intense research effort, the question if and how (high) dietary fructose intake interferes with human health has not yet been fully answered also as findings are sometimes contradictory. In the present narrative review, results of recent studies assessing the effect of fructose consumption on the development of metabolic disorders including hypertension, dyslipidemia, cardiovascular diseases (CVDs), hyperinsulinemia, and NAFLD as well as underlying molecular mechanisms are reviewed, thereby, aiming to further address the question if (high) fructose intake is a trigger of metabolic diseases.

The surface of intestinal epithelial cells is covered by the brush border, which consists of densely packed cellular extrusions called microvilli. Until recently, microvilli have not been known to be interconnected. In 2014, a protein complex, called the intermicrovillar adhesion complex (IMAC) which is located at the tips of the microvilli and responsible for the regular spatial organization of the brush border, was identified. Deletion of IMAC components such as cadherin-related family member-2 (CDHR2) in mice resulted in microvillus disorganization and fanning, a structural aberration that is also found in the brush border of patients with inflammatory bowel disease. The etiology of inflammatory bowel disease has been primarily associated with dysfunctional mucosal immunity, but the discovery of the IMAC may encourage theories of an epithelial origin. Here, possible effects of the brush border on the gut barrier function and intestinal inflammation are discussed proposing that the IMAC protects against inflammation through its microvillus cross-linking function.

Caspases are key factors in the regulation of the apoptotic and/or inflammatory responses, both crucial in the pathogenesis of diverse diseases. Caspase-2 is the most evolutionary conserved albeit functionally poorly defined member of the caspase family. The precise role of caspase-2 as an initiator or effector caspase is still unknown, but it has been involved in a wide variety of functions, from apoptosis to genomic stability, oxidative stress, metabolism, and cancer.

Normal hepatobiliary function depends on an adequate bile flow from the liver through the biliary tree to the gallbladder, where bile is stored and concentrated, and from the gallbladder to the duodenum when it is required for the digestive process. Interruption of this secretory function results in partial or complete cholestasis, which is accompanied by important repercussions due to the lack of bile acids in the intestine and their regurgitation from hepatocytes to blood together with potentially toxic compounds that are normally eliminated in bile. The presence of active and selective transporter proteins located at both poles of the plasma membrane of hepatocytes, cholangiocytes, and epithelial cells of the ileal mucosa, together with the ability of hepatocytes to synthesize bile acids from cholesterol, enables the so-called bile acid enterohepatic circulation, which is essential in liver and gastrointestinal tract physiology. The presence in the ducts of the biliary tree of agents reducing their luminal diameter by external compression or space-occupying obstacles, either in the duct wall or its lumen, can result in total or partial obstructive cholestasis. The clinical impact and management of cholestasis are different depending on the intrahepatic or extrahepatic location of the obstacle. Thus, surgical interventions can often be helpful in removing extrahepatic obstructions and restoring normal bile flow to the duodenum. In contrast, hepatocyte or cholangiocyte damage, either global, restricted to subcellular compartments, or more specifically affecting the elements of the canalicular secretory machinery, may result in hepatocellular cholestasis or cholangiopathies. In these cases, bile flow interruption is usually partial and, except for extremely severe cases when liver transplantation is required, these patients often treated with pharmacological agents, such as ursodeoxycholic acid (UDCA) and rifampicin. The present review gathers updated information on the etiopathogenesis and pathophysiological aspects of different types of cholestasis.

Aim:

Probiotic bacteria consumption for improving human health and for disease prevention is still controversial. There is a need to develop functional probiotic bacteria with proven efficacy for the human gastrointestinal (GI) system. The novel bacteria will lower the steady state of constant Ethanol production may lead to gut microbiota dysbiosis and liver injuries.

Methods:

Herein engineered probiotic bacterium B. subtilis to enhance the secretion of human alcohol dehydrogenase-4 (ADH4) by fusion of signal peptides (SPs) was constructed. As a result, higher ADH4 secretion and Ethanol removal rates were observed in phoB SP transformant SP-64, compared to other transformants. The engineered ADH4 expressing probiotic B. subtilis was delivered as spores to evaluate various physiological, biochemical, and immuno-histochemical parameters of mice under a high-fat diet (HFD)-induced obesity and metabolic impairment.

Results:

The treatment ameliorated significantly weight gain, improved glucose utilization, and prevented HFD-induced pancreatic damage. Lastly, SP-64 inoculation altered the gut microbiota, and increased the Firmicutes/Bacteroides ratio, supporting better fitness under HFD.

Conclusions:

SP-64 emerged as a potential probiotic that opens a new avenue for interventions against over-nutrition-induced metabolic disorders.

During liver injury and cholestasis, the mechanisms allowing the organ to protect itself with the aim of maintaining biliary homeostasis are not completely understood. Central to their biological roles, bile acids (BAs) and their receptors constitute a signaling network with multiple molecular and cellular impacts on both liver repair and protection from BA overload. BA signal through nuclear [mainly farnesoid X receptor (FXR)] and membrane [mainly G protein-coupled BA receptor 1 (GPBAR-1), aka Takeda G protein-coupled receptor 5 (TGR5)] receptors, in which activation elicits a wide array of biological responses. So far, most of the studies have been focused on FXR signaling as hepato-protective, TGR5 being less explored to this regard. While the liver faces massive and potentially harmful BA overload during cholestasis, it is crucial to understand that BAs induce also protective responses contributing not only to reduce the inflammatory burden, but also to spare liver cells and their repair capacities. Based on the available literature, the TGR5 BA receptor protects the liver in the cholestatic context and counteracts BA overload with the aim of restoring biliary homeostasis mainly through the control of inflammatory processes, biliary epithelial barrier permeability, and BA pool composition. Mouse experimental models of cholestasis reveal that the lack of TGR5 was associated with exacerbated inflammation and necrosis, leaky biliary epithelium, and excessive BA pool hydrophobicity, resulting in biliary cell and parenchymal insult, and compromising optimal restoration of biliary homeostasis and liver repair. There are thus widely opened translational perspectives with the aim of targeting TGR5-related signaling or biological responses to trigger protection of the cholestatic liver.

Metabolic zonation in the liver carries out the maintenance of organ and body homeostasis. Hypoxia is an inherent physiological feature of the liver and contributes to the zonal properties of the hepatic parenchyma. As a master regulator of hypoxia, the transcription factor hypoxia-inducing factor (HIF) is stabilized primarily by oxygen availability, and it is thought to contribute to steatohepatitis due to alcohol-related (ASH) and non-alcohol-related liver disease (NASH). Cholesterol has emerged as an important player in both diseases, and hypoxia increases hepatic cholesterol levels. Steroidogenic acute regulatory protein 1 (STARD1) is a mitochondrial outer membrane protein that transfers cholesterol to mitochondrial inner membrane for metabolic processing and acts as the rate-limiting step in the alternative pathway of bile acid synthesis in hepatocytes. STARD1 expression increases in ASH and NASH and determines the accumulation of cholesterol in mitochondria, which impacts the physico-chemical mitochondrial membranes properties and as a consequence impairs the activity of specific mitochondrial solute carriers, such as the 2-oxoglutarate carrier (2-OGC), limiting the exchange between cytosolic glutathione and mitochondrial 2-oxoglutarate (2-OG). Although HIF-1 is stabilized in hypoxia largely due to the requirement of prolylhydroxylases (PHDs) for oxygen to signal HIF degradation, PHDs are also dependent on 2-OG, and therefore it is conceivable that impairment of 2-OGC by STARD1-mediated cholesterol accumulation may contribute to HIF-1 stabilization due in part to decreased availability of cytosolic 2-OG. In this perspective, this review explores the interplay between HIF-1 stabilization and STARD1 induction and the potential contribution of this functional relationship to ASH and NASH.

Lysosomal hydrolases were once considered effectors of the waste disposal system of the cell, the endo-lysosomal system. However, they are now recognized as highly selective enzymes, which can modulate the function of several substrates, contributing to essential homeostatic and pathological cellular processes. There are more than 50 different lysosomal hydrolases that display optimal activity in the pH present in the acidic cellular compartment but can also be found in other cellular locations. They can work alone or in cooperation with other proteases building signaling pathways or amplification cascades. In the context of liver fibrosis lysosomal hydrolases, especially cysteine cathepsins have been described to participate in several fundamental cellular events contributing to the development, progression, perpetuation, and resolution of liver fibrosis. This paper comprehensively reviews the current knowledge on the contribution of lysosomal hydrolases to liver fibrosis.

Hereditary cholestasis comprises a broad spectrum of clinical phenotypes of varying severity. Severe forms such as progressive familial intrahepatic cholestasis (PFIC) mostly affect children with disease onset within their first years. Nevertheless, late-onset PFIC forms are increasingly diagnosed. Most adults present with less severe forms of hereditary cholestasis, often suffering from pruritus, gallstone disease, jaundice, or elevated liver enzymes. To identify the underlying genetic background and to rule out potential differential diagnoses, a broad genetic analysis like whole exome sequencing (WES) is recommended. Knowledge of the affected gene may have an impact not only on patient surveillance due to risk for disease progression or tumor development but also on potential therapeutic strategies. This case of the adult patient illustrates the importance of broad genetic analysis, which brought up the potentially relevant rare multidrug resistance protein 3 (MDR3) missense variant p.(Asn489Tyr) underlying the patient’s clinical phenotype of low phospholipid-associated cholelithiasis (LPAC). Patients with MDR3 disease may have an increased risk for cholangiocarcinoma (CCA) development and therefore need an individualized surveillance strategy. Most MDR3-affected patients benefit from life-long therapy with ursodeoxycholic acid (UDCA), which is well tolerated. Bezafibrate treatment can reduce pruritus, one of the main symptoms affecting the quality of life. Whether the administration of ileal bile acid transporter (IBAT) inhibitors is beneficial in adult patients with MDR3 disease is so far unknown.

Zebrafish as a preclinical drug induced liver injury (DILI) model provides multiple advantages ranging from ease of breeding and maintenance, availability of different strains and transgenic fish amenable to study liver function, and highly conserved liver structure and function with the human liver. In this review, the authors have aimed to provide an account of the metabolic enzymes that take roles in drug detoxification in both human and zebrafish in a comparative manner and exemplify several recent models in studying liver functionality. Moreover, the authors emphasize the difficulties associated with studying idiosyncratic DILI in preclinical models and propose that zebrafish could be an important complement to mice in testing functions of genes that are associated with DILI with respect to different drugs in human genome-wide association studies (GWAS) Catalog. Finally, this review highlights the state-of-the-art in the development of novel transgenic reporter strains that can be used to study degree and molecular mechanisms of hepatotoxicity caused by drugs in zebrafish. All of these will help researchers to use effectively the available resources in the zebrafish DILI models, while advocating potential leads that can be taken to provide advancements in a better understanding and treatment of DILI.

In this review, the authors have aimed to provide an account of the metabolic enzymes that take roles in drug detoxification in both human and zebrafish in a comparative manner and exemplify several recent models in studying liver functionality. Moreover, the authors emphasize the difficulties associated with studying idiosyncratic DILI in preclinical models and propose that zebrafish could be an important complement to mice in testing functions of genes that are associated with DILI with respect to different drugs in human genome-wide association studies (GWAS) Catalog. Finally, this review highlights the state-of-the-art in the development of novel transgenic reporter strains that can be used to study degree and molecular mechanisms of hepatotoxicity caused by drugs in zebrafish. All of these will help researchers to use effectively the available resources in the zebrafish DILI models, while advocating potential leads that can be taken to provide advancements in a better understanding and treatment of DILI. ,Gulcin Cakan-Akdogan ...

The late event onset of a fraction of idiosyncratic drug-induced liver injury (DILI) cases and the link observed by genome-wide association studies (GWASs) of certain human leucocyte antigen (HLA) alleles with DILI due to specific drugs support the crucial role of the immune system (both innate and adaptive) in the pathogenesis of DILI. Recent advances in both flow and mass cytometry have allowed the profiling of all major immune cell types in a given sample. Therefore, determining the lymphocyte populations in samples from patients with DILI would facilitate the development of specific biomarkers for DILI diagnosis and prognosis. To date, a few studies have explored the immune landscape in DILI. In a recent study of leukocyte immunophenotyping using flow cytometry from the Spanish DILI Registry, an important role of adaptive immune response in DILI is suggested. DILI patients had significantly higher levels of T helper 1 (Th1) cells and activated helper and cytotoxic T cells than healthy controls. Furthermore, the increased expression of negative immune checkpoints and ligands in DILI patients could reflect a restoration of the immune homeostasis. Differences in the profile of cytokines in DILI patients from the Drug-Induced Liver Injury Network (DILIN) also suggest an involvement of both innate and adaptive immune systems in DILI development and prognosis. Moreover, several studies based on immunophenotyping of liver infiltrates showed a distinctive pattern of cellular infiltrates in patients with immune checkpoint inhibitors (ICIs)-DILI, with lower levels of plasma cells, CD20+ B cells and CD4+ T cells than in autoimmune hepatitis (AIH) patients. These pioneering studies highlight the importance of immunophenotyping for the mechanistic understanding of DILI. In this review, available data on immunophenotyping in DILI are gathered, and the potential clinical applications of cutting-edge, novel immunophenotyping techniques are discussed.

The word “Kampo medicine” means the traditional Japanese herbal medicine. Even “natural herb” can cause drug-induced liver injury (DILI). In this review, the characteristics of Kampo medicine-induced liver injury (KMILI) are reported. The main causative herb involved in Kampo medicine is Scutellariae Radix. KMILI is based on certain hypersensitivity reactions. A small amount of Kampo medicine can cause liver injury, and KMILI can develop after a short latency period. The incidence of liver injury related to Scutellariae Radix is about 1%. KMILI is usually mild and not fatal. The latency period usually lasts 4 weeks to 24 weeks. Fatigue and loss of appetite are sometimes observed. Eosinophilia is not frequently observed. All three types of liver injuries are observed in KMILI: cholestatic, hepatocellular, and mixed types. In Japan, lymphocyte transformation test (LTT) has been generally used for the diagnosis of DILI; however, LTT is likely to yield false-positive result for Kampo medicines, and thus often leads to misdiagnosis in many cases. Recently, researchers reported that a specific human leukocyte antigen (HLA) genotype is possibly associated with KMILI. This hypothesis needs to be examined further. Although Kampo medicine is based on rich knowledge and experience that occurred over a period of thousands of years, much is still unknown about KMILI.

However, investigators have shown that both oxidative stress and endoplasmic reticulum (ER) stress play a significant role in the pathological mechanism. However, there is little in-depth literature about these two mechanisms. In order to prevent and improve the clinical symptoms of DILI, it is particularly important to study its pathogenesis.

Aim:

This is a Chinese population-based study aimed to determine the causes and clinical features of drug-induced liver injury (DILI) from traditional Chinese medicines (TCMs) and current Western medicines (WMs) and identify the risk factors of drug-induced liver failure (DILF) and chronic DILI for early recognition and better management.

Methods:

The medical records of patients who were diagnosed with DILI for at least six-month follow-up between January 2018 to December 2020 were reviewed and investigated. The risk factors of DILF and chronic DILI were identified by univariate and multivariate logistic regression analysis.

Results:

TCMs (47.5%) including herbal medicine (83.0% in TCM-induced DILI) and some Chinese patent drugs were the leading cause of DILI in the present study. Cholestatic type was more associated with severe and chronic DILI. Pre-existing gallbladder disease, initial total bilirubin (TBIL), initial prothrombin time (PT), initial antinuclear antibodies (ANA), and clinical classification are independent risk factors for DILF. Prolonged T0.5AST and T0.5GGT were independent risk factors for chronic DILI [area under the curve (AUC) = 0.812, 95% confidence interval (CI): 0.748–0.876, P < 0.001] with cut-off values of 8.5 days and 29.5 days, respectively.

Conclusions:

TCMs especially herbal medicine were the leading causes of DILI, and the risk of developing severe DILI was associated with pre-existing gallbladder disease, clinical classification, initial TBIL, PT, and ANA. T0.5AST and T0.5GGT might serve as indicators for chronicity.

Excessive alcohol intake is still among the leading causes of chronic liver diseases. Epidemiological studies suggest that per capita consumption of alcohol from various alcohol beverages e.g., beer, wine, or spirits, differs markedly between different areas of the world. Studies further suggest that different alcoholic beverages may impact the development of alcohol-related liver diseases (ALD) differentially. Specifically, results of several more recent epidemiological studies suggest that consumption of wine and herein especially of red wine may be less harmful in relation to the development of liver diseases than the intake of hard spirits. Results of studies evaluating the effects of beer on the development of ALD in humans are rather contradictory. Here, results of studies assessing the impact of wine, beer, and spirits on the development of ALD as well as possible underlying mechanisms are summarized and discussed.

A high consumption of ultra-processed food (UPF) is a hallmark of Western diets that has been related to increased risk of non-communicable diseases. As an underlying mechanism, UPF may promote non-alcoholic fatty liver disease (NAFLD) which is a key driver of metabolic impairment with extra-hepatic manifestations like type 2 diabetes, cardiovascular disease, chronic kidney disease, and osteoporosis among others. The present review provides an overview of UPF properties that may promote NAFLD and are thus potential targets for reformulation of UPF. Such approaches should address improvements in the quality of carbohydrates and fat, changes in food texture that lower eating rate as well as ingredients that prevent excess caloric intake or avoid dysbiosis and leaky gut syndrome. Promising strategies are enrichment with fiber, prebiotics, phytochemicals, and protein with a concurrent reduction in glycemic load, energy density, saturated fatty acids (FA; SFA), emulsifiers, fructose, and non-caloric sweeteners. Future studies are needed to examine the interactive and protective effects of such modifications in the composition of UPF on prevention and treatment of NAFLD.

Primary biliary cholangitis (PBC), previously known as primary biliary cirrhosis, is a rare chronic autoimmune cholestatic liver disease, affecting mostly females. With PBС develops chronic cholangiopathy, this is accompanied by the development of gradually progressive liver fibrosis, which leads to intrahepatic cholestasis. Defects in autoimmune tolerance are critical factors in the emergence of the disease. Biochemical signs in PBС appear already in the asymptomatic stage of the disease and they are associated with a disturbance of the secretion of bile acids. Understanding the pathophysiological mechanisms of these signs is essential to both the early diagnosis and treatment of PBC. Early diagnosis of the disease contributes to its more effective treatment. There are many scientifically based modern data on the pathophysiology of clinical and laboratory signs developing in PBС. The purpose of this review is to summarize the data available in the literature and those obtained by the authors on the mechanisms for the development of biochemical criteria for PBC and their diagnostic significance. The opportunity to present the pathophysiological mechanisms of the development of biochemical signs in patients with PBC is associated with the success in the development of modern research methods in biochemistry, molecular biology, and genetics.

Aim:

Modifications in long non-coding RNA (lncRNA) expression are associated with inflammation and fibrosis in chronic liver diseases. It has been recently demonstrated that human liver stem cells (HLSCs) and their extracellular vesicles (EVs) can effectively reduce inflammation and fibrosis in a murine model of non-alcoholic steatohepatitis (NASH). Now it has been evaluated whether EVs can modify the expression of inflammation-related lncRNAs in NASH liver.

Methods:

To induce NASH, severe combined immunodeficient mice were fed with a methionine-choline-deficient diet for 4 weeks. After 2 weeks of diet, 2.5 × 109 EVs were intravenously injected twice a week. An array of 84 inflammation-related lncRNAs was performed on the RNA isolated from NASH livers, and the expression of 14 selected lncRNAs was then validated by real-time polymerase chain reaction (PCR) analysis. Expression levels of maternally expressed gene 3 (Meg3) were further evaluated in vitro, in an activated human hepatic immortalized stellate cell line (LX-2) stimulated with EVs.

Results:

The screening showed an altered lncRNA expression profile in the liver of NASH mice, in respect to control healthy mice. EV treatment modulated several inflammation-related lncRNAs in NASH livers. Real-time PCR validation of array results indicated that EVs restored to normal levels the expression of 10 lncRNAs altered in NASH. In particular, EV stimulation reduced Meg3 expression levels, which were increased in NASH as well as in activated LX-2.

Conclusions:

HLSC-EVs regulate the expression of inflammation-related lncRNAs impaired in NASH livers and in an in vitro model of liver fibrosis.

Nonalcoholic fatty liver disease (NAFLD) is an umbrella definition that describes the ectopic deposition of fat within the liver that occurs in the absence of inciting factors other than the metabolic syndrome and its individual features. NAFLD has a multi-factorial pathogenesis which determines heterogeneous clinical phenotypes and variable natural course spanning from liver-related (steatohepatitis, fibrosis, cirrhosis, hepatocellular carcinoma) to extrahepatic outcomes (cardio-metabolic and cancer). This narrative review article leverages the key aspects of disease natural history as the background information to discuss studies that may inform strategies to risk-stratify NAFLD patients. Evaluation of hepatic fibrosis with non-invasive tools, including blood-based biomarkers and imaging-based elastometry techniques, seemingly retains the core information useful to predict the heterogeneous outcomes listed above. Additionally, genetic testing and metabolomic profiles may also be utilized to this end. In conclusion, a comprehensive understanding of the variable hepatic, cardio-metabolic and cancer outcomes of NAFLD may enable physicians and researchers to risk-stratify and accurately identify the multilayered prognosis of NAFLD individuals while also defining homogeneous patient subsets to enroll in clinical trials.

Drug-induced liver injury (DILI) is an adverse reaction to drugs and other xenobiotics that can have serious consequences and jeopardise progress in pharmacological therapy. While DILI is predominantly hepatocellular, a non-negligible percentage of patients who present with cholestatic damage. Mixed damage is typically lumped together with cholestatic damage in the literature. Drug-induced cholestasis is often caused by the use of some non-steroidal anti-inflammatory drugs (NSAIDs), antibiotics (i.e., amoxicillin-clavulanic acid), statins, and anabolic agents, among others. Drug-associated cholestasis tends to have a more chronic course and mostly affects older population. There is also a genetic predisposition to toxic cholestasis caused by some drugs (amoxicillin-clavulanic acid, statins, etc.). Recently, anatomical alterations of the biliary tract induced by drugs (especially immunotherapy drugs) have been described. Bile duct injury is one of the histopathological findings that have prognostic significance in DILI. A correct differential diagnosis with other causes of cholestasis is mandatory to reach an accurate diagnosis. Ursodexycholic acid, corticosteroids, and replacement therapies have been used as a therapeutic arsenal, although more evidence is needed to establish them as a routine therapeutic management in clinical practice. The breakthrough and validation of biomarkers of cholestasis and bile duct injury is an urgent need for drug development and post-marketing phase.

The pathogenesis of primary biliary cholangitis (PBC) is particularly complicated as both intrinsic and extrinsic factors are implicated. Several forms of cellular death, both programmable and non-programmable, operate leading biliary epithelial cells (BECs) to elimination. The precise role of critical pathways like autophagy, apoptosis, senescence, and their interplay has not been fully clarified. Therefore, in this review, data on these important mechanisms are presented and their implication in PBC is discussed.

Several forms of cellular death, both programmable and non-programmable, operate leading biliary epithelial cells (BECs) to elimination. The precise role of critical pathways like autophagy, apoptosis, senescence, and their interplay has not been fully clarified. Therefore, in this review, data on these important mechanisms are presented and their implication in PBC is discussed. The interplay of the three mechanisms is examined and the factors that drive them are analyzed. Moreover, the upstream drivers of autophagy, apoptosis, and senescence are presented.

Non-alcoholic fatty liver disease (NAFLD) is the leading chronic liver disease worldwide, with a progressive form of non-alcoholic steatohepatitis (NASH). It may progress to advanced liver diseases, including liver fibrosis, cirrhosis, and hepatocellular carcinoma. NAFLD/NASH is a comorbidity of many metabolic disorders such as obesity, insulin resistance, type 2 diabetes, cardiovascular disease, and chronic kidney disease. These metabolic diseases are often accompanied by systemic or extrahepatic inflammation, which plays an important role in the pathogenesis and treatment of NAFLD or NASH. Metabolites, such as short-chain fatty acids, impact the function, inflammation, and death of hepatocytes, the primary parenchymal cells in the liver tissue. Cholangiocytes, the epithelial cells that line the bile ducts, can differentiate into proliferative hepatocytes in chronic liver injury. In addition, hepatic non-parenchymal cells, including liver sinusoidal endothelial cells, hepatic stellate cells, and innate and adaptive immune cells, are involved in liver inflammation. Proteins such as fibroblast growth factors, acetyl-coenzyme A carboxylases, and nuclear factor erythroid 2-related factor 2 are involved in liver metabolism and inflammation, which are potential targets for NASH treatment. This review focuses on the effects of metabolic disease-induced extrahepatic inflammation, liver inflammation, and the cellular and molecular mechanisms of liver metabolism on the development and progression of NAFLD and NASH, as well as the associated treatments.

Aim:

Familial achalasia (FA) is a very rare condition. This work aims to evaluate its prevalence, characterize its clinical profile in a large series, and assess the efficacy and safety of pneumatic dilation (PD) in this context.

Methods:

A total of 817 patients with achalasia were collected over a period of 20 years (1990–2010). All cases of FA: isolated or associated to Allgrove syndrome, were looked for in both parents and siblings.

Results:

In this study, 18 families with FA were identified n = 41 patients (5%). Two members were affected in each family, in 14 families, three members per family in three others, and for the remaining family 04 members. All cases of achalasia were observed in siblings and parent to child transmission was unfound. Achalasia was associated to Allgrove syndrome in 15 families. It was isolated in 3 families. Consanguinity was found in 89% of patients, and death at a young age in the siblings was recorded in 27% of cases. Achalasia was present before the age of 5 years in 75% of cases. There was no difference between the two groups for age, age at onset, sex and the presence of the cardinal signs of achalasia. A total of 102 dilations were performed. Only one session in 31% of cases, two in 38%, three in 17% and more than three sessions in 14%. The long-term success rate of PD was low.

Conclusions:

FA manifests almost exclusively in childhood. It is rarely isolated; most often falls under Allgrove syndrome. Alacrima is the earliest sign that should lead to the diagnosis. The long-term success rate of PD is rather low. This requires recourse to multiple sessions of PD or Heller’s cardiomyotomy which may be the best initial approach.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is one of the most common chronic liver diseases. Over time, there has been a significant increase in the prevalence of MASLD. It has become one of the leading causes of hepatocellular carcinoma (HCC) in the United States, France, and the United Kingdom. Globally, the incidence of HCC related to MASLD may further increase with the growing prevalence of obesity. Non-alcoholic steatohepatitis (NASH) is an important stage of MASLD, which is more likely to cause cirrhosis and even HCC. And patients with NASH cirrhosis have a much higher incidence of hepatocellular cancer than patients with non-cirrhotic MASLD. As a result, it is critical to investigate the targets of MASLD therapy in HCC. This article reviews therapeutic targets of MASLD, such as farnesoid X receptor (FXR), peroxisome proliferator activated receptor (PPAR), fibroblast growth factor-21 (FGF-21), etc., and introduces the drugs related to these targets and their mechanisms of action in HCC. In addition, the developmental process and pathogenesis of MASLD, as well as risk factors for HCC development, are discussed. These are of great significance for the prevention and treatment of HCC.

Aim:

In Switzerland, the first access to interferon-free direct-acting antivirals (DAAs) for hepatitis C virus (HCV) treatment was in 2014. This study aimed to analyze the effects of DAAs on the yearly listed numbers of HCV RNA-positive (RNA+) patients and their mortality on the Swiss organ transplantation waiting list (SOWL).

Methods:

In this retrospective secondary time series analysis of yearly aggregated data on listed and delisted patients from a subset of HCV RNA+ patients on the SOWL, listed patients were grouped by the requested organ, and delisted patients by reason. Time series were split into two periods of equal length, the phases before and after DAA implementation, and the mean difference was tested using the Mann-Whitney U test.

Results:

From 2008 to 2019, 328 HCV RNA+ patients were listed on SOWL, 86.6% requesting liver, 11.6% kidney, and 1.8% other organ transplantations. A total of 285 RNA+ patients were delisted from SOWL: 14.7% died, 75.4% had been transplanted, and 9.8% were delisted without surgery. There were significant reductions of patients listed for requesting any organ (–21.7, P = 0.004), liver (–18.3, P = 0.004), or kidney (–3.0, P = 0.031) comparing the periods before and after DAA launch. The mean number of delistings after transplantation (–11.2, P = 0.010), or death (–4, P < 0.001) show a significant reduction.

Conclusions:

With DAAs, the rising trend of HCV RNA+ people waiting for organs was broken, as was the increasing trend of mortality on the SOWL among HCV RNA+ individuals.

Results: From 2008 to 2019, 328 HCV RNA+ patients were listed on SOWL, 86.6% requesting liver, 11.6% kidney, and 1.8% other organ transplantations. A total of 285 RNA+ patients were delisted from SOWL: 14.7% died, 75.4% had been transplanted, and 9.8% were delisted without surgery. There were significant reductions of patients listed for requesting any organ (–21.7, P = 0.004), liver (–18.3, P = 0.004), or kidney (–3.0, P = 0.031) comparing the periods before and after DAA launch. The mean number of delistings after transplantation (–11.2, P = 0.010), or death (–4, P < 0.001) show a significant reduction. Conclusions: With DAAs, the rising trend of HCV RNA+ people waiting for organs was broken, as was the increasing trend of mortality on the SOWL among HCV RNA+ individuals. ,Luis Falcato ...

Aim:

This study aims to determine the significance of chronic hyperglycemia for the reduced efficacy of eradication therapy in patients with type 2 diabetes mellitus (T2DM) and Helicobacter pylori (H. pylori)-associated upper gastrointestinal tract pathology as well as for H. pylori survival.

Methods:

A prospective randomized study with the participation of 180 patients (87 men and 93 women) with H. pylori-associated upper gastrointestinal pathology was carried out. Ninety of these patients were with T2DM and 90 were without diabetes mellitus (DM). The patients were divided into 4 groups of 45 patients: the group 1 included non-diabetic patients treated with the classical triple eradication scheme; the group 2 included patients with T2DM treated with the classical triple eradication scheme; the group 3 included non-diabetic patients treated with bismuth quadro-therapy; the group 4 included patients with T2DM treated with bismuth quadro-therapy. The presence of H. pylori and evaluation of eradication efficacy was carried out using the Helix breath test.

Results:

The effectiveness of 1st line anti-Helicobacter therapy was higher (88.2%) in patients without diabetes in comparison with the group of patients with concomitant T2DM (74.7%). The efficacy of classical triple eradication therapy in patients with concomitant T2DM was 69.1%, and quadro-therapy was 80.5%. There was significantly lower effectiveness (P < 0.017) of eradication therapy in patients with T2DM and glycated hemoglobin (HbA1c) level ≥ 7.0% as compared with the group of patients in whom the target (≤ 6.5%) level of HbA1c was achieved.

Conclusions:

Chronic hyperglycemia has a favorable effect on the viability of H. pylori bacteria in patients with T2DM. A hypothesis explaining the reduced efficacy of eradication therapy in patients with hyperglycemia has been proposed.

Drug-induced liver injury (DILI) poses a complex and heterogeneous clinical challenge, which often resembles non-drug related acute or chronic liver diseases, such as metabolic dysfunction-associated steatotic liver disease (MASLD). Furthermore, certain drugs can induce hepatic steatosis, which is considered a rare variant of hepatotoxicity. Additionally, the detection and diagnosis of DILI in patients with non-alcoholic liver disease present additional challenges that require attention. The importance of achieving an accurate diagnosis is highlighted by the different therapeutic approaches needed for each of these diseases. Nonetheless, as definitive diagnostic tests and distinct biomarkers often remain elusive, the differential diagnosis must rely on a combination of clinical, biochemical, histological, and immunophenotypic profiling. The diagnosis of hepatotoxicity is predicated upon the temporal nexus between the administration of a potentially hepatotoxic drug and the onset of hepatic injury, concomitantly excluding alternative hepatic pathologies. More frequently, this condition presents an acute course, with a more pronounced elevation of cytolytic and cholestatic parameters as compared to fatty liver disease. Advances in elucidating the underlying mechanisms hold promise for bolstering the diagnosis and management of these conditions. This article aims to thoroughly examine and emphasize the currently available scientific evidence to provide valuable insights into the diagnostic strategies for DILI, metabolic-associated liver disease, and drug-induced steatosis (DIS).

Hunting for tumoral material in body fluids, traditionally in blood, the so-called liquid biopsy is set to revolutionize the diagnosis and management of oncological patients. However, other biofluids can also be considered as alternative sources of biomarkers to provide clinically valuable information for multiple diseases. This is the case of bile, a fluid produced in the liver, stored in the gallbladder, and excreted to the duodenum, which complex composition is known to change in different pathological conditions. Remarkably, different works have demonstrated that the identification of mutations in bile cell-free DNA (cfDNA) can outperform blood analysis for the early diagnosis of biliopancreatic tumors causing biliary strictures. Here, the literature in which bile has been tested as a liquid biopsy matrix where lipids, metabolites, proteins, and cfDNA among other analytes were measured is reviewed. Moreover, the clinical situations and procedures where bile can be available, discussing the possible applications and limitations of bile analysis are summarized. The scientific relevance and clinical potential of bile harvesting, biobanking, and analysis are put forward. All this evidence supports the value of bile as a liquid biopsy matrix for the management of patients beyond cancer, and perhaps also beyond “blood, sweat, and tears”.

Mitochondria are present in all mammalian cells except matured red blood cells. Mitochondria consist of several metabolic pathways for glucose, fatty acids, amino acids, and bioenergetic pathways for ATP synthesis, membrane potential, and reactive oxygen production. In the liver, hepatic mitochondria play a key role in hepatic steatosis because mitochondrial metabolism produces acetyl-CoA which is the building block for synthesis of lipids and cholesterol. Mitochondria inner membrane is impermeable of metabolites, reducing equivalents, and small molecules such as phosphate, and sulfate. Thus, mitochondrial shuttles and carriers function as the routes of influx and efflux of these metabolites and molecules across the inner membrane. The signal regulation of these shuttles and mitochondrial enzymes could play a key role in coordinating the mitochondrial metabolism to adapt the cytosolic part of metabolic pathways in liver metabolic stress. Intriguingly, the interaction of mitochondria protein SH3 domain-binding protein 5 (SAB/SH3BP5) and c-Jun N-terminal kinase (JNK) was found as a pivotal role in sustained activation of JNK and phosphorylated-JNK (P-JNK) mediated activation of lipogenic pathway in nutritional excess. Knockout or knockdown of SAB prevented or reversed the hepatic steatosis, inflammation, and fibrosis, and improved metabolic intolerance and energy expenditure. Moreover, blocking the SAB peptide prevents palmitic acid-induced P-JNK interaction with SAB and inhibition of mitochondrial bioenergetics, implying the P-JNK effect on mitochondrial metabolism. This review focuses on the flow of mitochondrial metabolites in metabolic stress conditions and the contribution of mitochondria and mitochondrial stress signals in hepatic steatosis.

Mitochondria consist of several metabolic pathways for glucose, fatty acids, amino acids, and bioenergetic pathways for ATP synthesis, membrane potential, and reactive oxygen production. In the liver, hepatic mitochondria play a key role in hepatic steatosis because mitochondrial metabolism produces acetyl-CoA which is the building block for synthesis of lipids and cholesterol. Mitochondria inner membrane is impermeable of metabolites, reducing equivalents, and small molecules such as phosphate, and sulfate. Thus, mitochondrial shuttles and carriers function as the routes of influx and efflux of these metabolites and molecules across the inner membrane. The signal regulation of these shuttles and mitochondrial enzymes could play a key role in coordinating the mitochondrial metabolism to adapt the cytosolic part of metabolic pathways in liver metabolic stress. Intriguingly, the interaction of mitochondria protein SH3 domain-binding protein 5 (SAB/SH3BP5) and c-Jun N-terminal kinase (JNK) was found as a pivotal role in sustained activation of JNK and phosphorylated-JNK (P-JNK) mediated activation of lipogenic pathway in nutritional excess. Knockout or knockdown of SAB prevented or reversed the hepatic steatosis, inflammation, and fibrosis, and improved metabolic intolerance and energy expenditure. Moreover, blocking the SAB peptide prevents palmitic acid-induced P-JNK interaction with SAB and inhibition of mitochondrial bioenergetics, implying the P-JNK effect on mitochondrial metabolism. This review focuses on the flow of mitochondrial metabolites in metabolic stress conditions and the contribution of mitochondria and mitochondrial stress signals in hepatic steatosis. ,Sanda Win ...

Autoimmune hepatitis (AIH) is a chronic liver disease of unknown aetiology that can lead to end stage liver disease if left without treatment. Corticosteroids with or without azathioprine (AZA) are considered the recommended standard first-line treatment option for the induction and maintenance of remission. The aim of treatment is to achieve complete biochemical response (CBR), defined by normal transaminases and immunoglobulin G (IgG) within 6–12 months after treatment initiation. However, response rates to standard treatment vary widely as approximately 10–25% of cases develop intolerance, insufficient response, or rarely non-response to AZA. Mycophenolate mofetil (MMF) is an effective and safe alternative first-line treatment in AIH, based on its high rates of CBR among treatment-naive patients, but can also be considered as second-line drug in patients with poor response or intolerance to AZA. However, even after the administration of second line treatment there is a small proportion of patients with refractory disease that bear the highest probability of developing decompensated cirrhosis and hepatocellular carcinoma. For this difficult to treat subgroup of patients third-line treatments are warranted. Therefore, the aim of this review is to summarize the current evidence on second- and third-line therapies for AIH, as well as, to set the background for future perspectives on safer and more efficient treatment strategies.

Aim:

Extracellular vesicles (EVs) have gained significant attention for their diagnostic and therapeutic potential in various diseases, including liver disorders. This study focuses on optimizing the isolation and characterization of small EVs from plasma and serum samples in patients with liver diseases, aiming to advance our understanding and potential clinical applications of EVs.

Methods:

Blood samples were collected from patients with end-stage liver disease (ESLD) enlisted in the TransplantLines Cohort and Biobank Study, and healthy donors. We employed differential ultracentrifugation (DUC) to evaluate three distinct protocols: a 3-step DUC, a washing step omitted [samples without washing (WW)], and a contaminant-depleted plasma (CDP) protocol. RNA isolation methodologies were compared, involving the use of TRI-reagent or the commercial AllPrep DNA/RNA kit. Further insights into EV composition were obtained through proteomic analyses, comparing samples subjected to traditional cell lysis (L) with those processed without lysis (NL).

Results:

We successfully isolated EVs from both plasma and serum samples as confirmed by the presence of specific EV markers, including CD9, CD63, CD81, and tumor susceptibility gene 101 (TSG-101). While some contaminants remained, such as albumin and lipoproteins, the protocol selected to continue EVs analysis was the 3-step protocol. Transmission electron microscopy (TEM) and nanotracking analysis (NTA) further confirmed EVs presence. RNA extraction was achieved using TRI-reagent, but not with the commercial kit highlighting the importance of selecting an appropriate method for RNA isolation. Finally, proteomics analysis showed that lysed samples were significantly more enriched in proteins compared to non-lysed samples, although protein variability was still present in both groups.

Conclusions:

Optimizing EV isolation techniques is essential for harnessing their potential in liver disease diagnosis and therapy. Further refinement of purification methods, a deep characterization of our cohort and understanding the variability and cargo within EVs will be crucial for future biomarker discovery and therapeutic applications in liver-related diseases.

Methods: Blood samples were collected from patients with end-stage liver disease (ESLD) enlisted in the TransplantLines Cohort and Biobank Study, and healthy donors. We employed differential ultracentrifugation (DUC) to evaluate three distinct protocols: a 3-step DUC, a washing step omitted [samples without washing (WW)], and a contaminant-depleted plasma (CDP) protocol. RNA isolation methodologies were compared, involving the use of TRI-reagent or the commercial AllPrep DNA/RNA kit. Further insights into EV composition were obtained through proteomic analyses, comparing samples subjected to traditional cell lysis (L) with those processed without lysis (NL). Results: We successfully isolated EVs from both plasma and serum samples as confirmed by the presence of specific EV markers, including CD9, CD63, CD81, and tumor susceptibility gene 101 (TSG-101). While some contaminants remained, such as albumin and lipoproteins, the protocol selected to continue EVs analysis was the 3-step protocol. Transmission electron microscopy (TEM) and nanotracking analysis (NTA) further confirmed EVs presence. RNA extraction was achieved using TRI-reagent, but not with the commercial kit highlighting the importance of selecting an appropriate method for RNA isolation. Finally, proteomics analysis showed that lysed samples were significantly more enriched in proteins compared to non-lysed samples, although protein variability was still present in both groups. Conclusions: Optimizing EV isolation techniques is essential for harnessing their potential in liver disease diagnosis and therapy. Further refinement of purification methods, a deep characterization of our cohort and understanding the variability and cargo within EVs will be crucial for future biomarker discovery and therapeutic applications in liver-related diseases. ,Magnolia Martínez-Aguilar ...

The most common type of liver cancer is hepatocellular carcinoma (HCC) causes a lower survival rate even after systemic treatment. Previous studies have shown evidence that various molecular and epigenetic mechanisms are involved in the transition of HCC from normal liver cells. Epigenetics plays an important role in maintaining genomic stability in normal liver cells. Apart from the mutation of genes, epigenetic factors are involved in HCC progression. miRNA tends to be a major epigenetic factor involved in regulating major cell cycle pathways. miRNA regulates the HCC progression by inhibiting the major apoptotic pathways and favors angiogenesis and tumor microenvironment. Apart from regulating major pathways, miRNA appears to regulate tight junction integrity. Tight junction proteins appear to be strong barrier proteins involved in cell adhesion and integrity. Disturbance in cell adhesion and integrity leads to the major dysregulation of cell cycle resulting in cancer progression. Moreover, dysregulation of tight junction integrity was observed in the pathogenesis of HCC. The regulation of tight junction proteins via miRNA were studied in various diseases. Here, we discussed the regulation of tight junction proteins via miRNA in HCC progression. This review may focus on the significance of miRNA in cellular function and its role in regulating tight junction proteins that impact in HCC progression which opens a new approach to develop a new diagnostic marker for an early detection of HCC and novel therapeutic approach against HCC.

Hepatitis B surface antigen (HBsAg) seroclearance is considered the functional cure and the optimal treatment endpoint for chronic hepatitis B (CHB). Patients with CHB who cleared HBsAg generally have a favorable clinical course with minimal risk of developing hepatocellular carcinoma (HCC) or cirrhotic complications. Nevertheless, a minority of patients still develop HCC despite HBsAg seroclearance. While patients with liver cirrhosis are still recommended for HCC surveillance, whether other non-cirrhotic patients who achieved HBsAg seroclearance should remain on HCC surveillance remains unclear. This review provides an overview of the incidence of HBsAg seroclearance, the factors associated with the occurrence of HBsAg seroclearance, the durability of HBsAg seroclearance, the risk of developing HCC after HBsAg seroclearance, the risk factors associated with HCC development after HBsAg seroclearance, the role of HCC risk scores, and the implications on HCC surveillance. Existing HCC risk scores have a reasonably good performance in patients after HBsAg seroclearance. In the era of artificial intelligence, future HCC risk prediction models based on artificial intelligence and longitudinal clinical data may further improve the prediction accuracy to establish a foundation of a risk score-based HCC surveillance strategy. As different novel hepatitis B virus (HBV) antiviral agents aiming at HBsAg seroclearance are under active development, new knowledge is anticipated on the natural history and HCC risk prediction of patients treated with new HBV drugs.

Aim:

This study aimed to develop and evaluate an in-house enzyme-linked immunosorbent assay (ELISA) based on autochthonous antigens to detect immunoglobulin G (IgG) antibodies against Helicobacter pylori (H. pylori) in adult sera.

Methods:

Whole-cell antigens from three genetically characterized clinical isolates of H. pylori were mixed and used as coating antigens. This assay was validated with a panel of human sera samples of H. pylori seropositive and seronegative patients. Likewise, sera samples from patients with uninvestigated dyspepsia, who were also evaluated by invasive and noninvasive tests (i.e., histopathology, rapid urease test, and stool antigen test), blood donors and patients with confirmed viral and parasitic diseases were also collected. The IgG response against H. pylori was detected by the in-house assay using the commercial ELISA IBL (Germany), as a reference test. Statistical analysis was performed with GraphPad Prism version 5.01.

Results:

The in-house ELISA showed high repeatability and reproducibility. Sensitivity was 91.1%; 95% confidence interval (CI): 87.2–94.0, specificity was 94.8% (95% CI: 85.0–94.8), and accuracy was 91.6% (95% CI: 88.5–94.6). The in-house ELISA showed an excellent area under the curve (0.96; 95% CI: 0.93–0.98) and a better IgG detection by the inverse cumulative distribution. The frequency of seropositivity in patients with dyspepsia (76.0%) was significantly higher (P < 0.05) than in healthy individuals (57.7%) and patients with other infectious diseases resembling H. pylori infection symptoms (54.4%). The H. pylori seroprevalence was estimated to be 62.7%. A good correlation was found between IgG seropositivity and H. pylori infection diagnosed by histopathology, rapid urease test, and stool antigen test in Cuban adults with dyspepsia.

Conclusions:

The in-house ELISA demonstrated good diagnostic accuracy and potential usefulness for estimating H. pylori exposure in the adult population, henceforward, this method could be used as an alternative for H. pylori diagnosis in the Cuban setting.

Hepatocellular carcinoma (HCC) is the most common type of liver cancer and its death rate is rising faster than that of any other cancer, while we still lack effective treatments. The increasing incidence of liver cancer in western countries is closely associated with the growing prevalence of metabolic dysfunction-associated steatohepatitis (MASH) linked to metabolic diseases. While the contribution of lipids in the progression of MASH pathogenesis and its progression to HCC is well recognized, the specific contribution of cholesterol is subject to controversy. The liver plays a central role in cholesterol metabolism, where the majority of its biosynthesis, storage, excretion, recycling, and conversion into bile acids occur. Moreover, cholesterol is implicated in numerous hepatocyte cellular processes, encompassing endoplasmic reticulum function, formation of lipid microdomains in the plasma membrane, metabolism of lipoproteins, and mitochondrial function and performance. Therefore, it is not surprising that cholesterol plays key roles in initiation, promotion, and survival of HCC cells and there are several lines of evidence pointing to that cancer cells are subverting cholesterol metabolism to foster their proliferation and survival through various mechanisms. This narrative review provides a concise overview of the physiological and pathological roles of cholesterol in the transition from healthy hepatocytes to HCC, in the context of MASH. Gaining further understanding of how hepatic cancer cells disrupt cholesterol homeostasis and how these perturbations impact cancer progression will facilitate the identification of novel and more effective cancer treatment strategies in this complex and devastating disease.

Hepatitis C viral infections present a significant global health challenge, carrying substantial economic implications. These infections manifest in various clinical forms, including acute and chronic hepatitis, liver cirrhosis, hepatic failure, and hepatocellular carcinoma (HCC). Liver cirrhosis and HCC emerge as the primary contributors to mortality in hepatitis virus-induced liver diseases. To alleviate the public health impact of this disease, it is imperative to enhance the diagnosis and treatment rates among hepatitis C virus-infected individuals. The advent of direct-acting antivirals (DAAs), especially pan-genotypic regimens such as a combination of sofosbuvir and velpatasvir, has shown remarkable progress in achieving hepatitis C cure. However, potential obstacles, such as drug adverse effects and resistance-associated substitutions (RASs), warrant attention. Managing chronic hepatitis C (CHC) requires tailored treatment plans, vigilant monitoring, and judicious re-treatment strategies.

These infections manifest in various clinical forms, including acute and chronic hepatitis, liver cirrhosis, hepatic failure, and hepatocellular carcinoma (HCC). Liver cirrhosis and HCC emerge as the primary contributors to mortality in hepatitis virus-induced liver diseases. To alleviate the public health impact of this disease, it is imperative to enhance the diagnosis and treatment rates among hepatitis C virus-infected individuals. The advent of direct-acting antivirals (DAAs), especially pan-genotypic regimens such as a combination of sofosbuvir and velpatasvir, has shown remarkable progress in achieving hepatitis C cure. However, potential obstacles, such as drug adverse effects and resistance-associated substitutions (RASs), warrant attention. Managing chronic hepatitis C (CHC) requires tailored treatment plans, vigilant monitoring, and judicious re-treatment strategies. ,Hao Xiong, Jinsheng Guo [PublishedText] => Published [IsEdit] => 0 [AccountId] => 69 [Zh] => 0 [AuthorsName] => ) [49] => Array ( [ArticleId] => 1409 [Create_Time] => 2024-07-05 [zipUrl] => https://www.explorationpub.com/uploads/zip/202407/20240705053453.zip [xmlUrl] => https://www.explorationpub.com/uploads/Article/A100550/100550.xml [pdfUrl] => https://www.explorationpub.com/uploads/Article/A100550/100550.pdf [coverUrl] => https://www.explorationpub.com/uploads/Article/A100550/100550_cover.png [JournalsId] => 6 [Title] => Transabdominal Gastro-Intestinal UltraSound (GIUS): a visual approach to intestinal pathology [Abstract] => Transabdominal ultrasound is a valuable diagnostic approach for evaluating the gastrointestinal tract and related disorders.

Transabdominal ultrasound is a valuable diagnostic approach for evaluating the gastrointestinal tract and related disorders. This dynamic examination provides real-time visualization of the digestive tube and surrounding structures, assessment of peristaltic movements, estimation of compressibility of intestinal loops, and recognition of painful spots requiring specific attention. Since ultrasound imaging is non-invasive, painless, reproducible, inexpensive and requires no special preparation, it is used as a major diagnostic tool in emergency settings and in outpatient follow-up of several disorders. Costs, encompassing both accessibility and actual procedural expenses, are lower than those associated with other diagnostic techniques. However, the incorporation of gastro-intestinal ultrasound (GIUS) in clinical practice has not been widely used on a global scale. The purpose of this paper is to provide an overview of the execution techniques as well as the main areas of application for GIUS. Through illustrative iconographic representation, emphasis was placed on its potential within the diagnostic and therapeutic pathway of various acute and chronic gastrointestinal disorders.
