Abstract
Alcohol-related hepatitis (ARH) is a unique type of alcohol-associated liver disease characterized by acute liver inflammation caused by significant alcohol use. It ranges in severity from mild to severe and carries significant morbidity and mortality. The refinement of scoring systems has enhanced prognostication and guidance of clinical decision-making in the treatment of this complex disease. Although treatment focuses on supportive care, steroids have shown benefit in select circumstances. There has been a recent interest in this disease process, as coronavirus disease 2019 pandemic led to substantial rise in cases. Although much is known regarding the pathogenesis, prognosis remains grim due to limited treatment options. This article summarizes the epidemiology, genetics, pathogenesis, diagnosis and treatment of ARH.

Abstract
Alcoholic and non-alcoholic fatty liver diseases have become a serious concern worldwide. Both these liver diseases have an identical pathology, starting from simple steatosis to cirrhosis and, ultimately to hepatocellular carcinoma. Treatment options for alcoholic liver disease (ALD) are still the same as they were 50 years ago which include corticosteroids, pentoxifylline, antioxidants, nutritional support and abstinence; and for non-alcoholic fatty liver disease (NAFLD), weight loss, insulin sensitizers, lipid-lowering agents and anti-oxidants are the only treatment options. Despite broad research in understanding the disease pathophysiology, limited treatments are available for clinical use. Some therapeutic strategies based on targeting a specific molecule have been developed to lessen the consequences of disease and are under clinical investigation. Therefore, focus on multiple molecular targets will help develop an efficient therapeutic strategy. This review comprises a brief overview of the pathogenesis of ALD and NAFLD; recent molecular drug targets explored for ALD and NAFLD that may prove to be effective for multiple therapeutic regimens and also the clinical status of these promising drug targets for liver diseases.

Abstract
BACKGROUND Hepatitis is a liver inflammation caused by different agents and remains a public health problem worldwide. Medicinal plants are an important source of new molecules being considered for treatment of this disease. Our work aims at evaluating the hepatoprotective properties of Neoboutonia velutina, a Cameroonian medicinal plant. METHODS The aqueous extract has been prepared using phytochemical methods. HepG2 cells were used to assess anti-inflammatory properties of the extract at different concentrations. Acute hepatitis models (Carbon tetrachloride and Concanavalin A) were performed in mice receiving or not receiving, different extract doses by gavage. Liver injury was assessed using histology, transaminases and pro-inflammatory markers. Extract antioxidant and radical scavenging capacities were evaluated. RESULTS The extract led to a significant decrease in pro-inflammatory cytokine expression in vitro and to a remarkable protection of mice from carbon tetrachloride-induced liver injury, as shown by a significant decrease in dose-dependent transaminases level. Upon extract treatment, inflammatory markers were significantly decreased and liver injuries were limited as well. In the Concanavalin A model, the extract displayed weak effects. CONCLUSIONS Taking into account underlying mechanisms in both hepatitis models, we demonstrate the extract's radical scavenging capacity. Neoboutonia velutina displays a potent hepatoprotective effect mediated through radical scavenging properties.

Abstract
Severe alcoholic hepatitis is implicated as a costly, worldwide public health issue with high morbidity and mortality. The one-month survival for severe alcoholic hepatitis is low with mortality rates high as 30%-50%. Abstinence from alcohol is the recommended first-line treatment. Although corticosteroids remain as the current evidence based option for selected patients with discriminant function > 32, improvement of short-term survival rate may be the only benefit. Identification of individuals with risk factors for the development of severe alcoholic hepatitis may provide insight to the diverse clinical spectrum and prognosis of the disease. The understanding of the complex pathophysiologic processes of alcoholic hepatitis is the key to elucidating new therapeutic treatments. Newer research describes the use of gut microbiota modification, immune modulation, stimulation of liver regeneration, caspase inhibitors, farnesoid X receptors, and the extracorporeal liver assist device to aid in hepatocellular recovery. Liver transplantation can be considered as the last medical option for patients failing conventional medical interventions. Although the preliminary data is promising in patients with low risk of recividism, controversy remains due to organ scarcity. This review article comprehensively summarizes the epidemiology, pathophysiology, risk factors, and prognostic indicators of severe alcoholic hepatitis with a focus on the current and emerging therapeutics.

Abstract
Alcoholic hepatitis (AH) is defined as an acute hepatic manifestation resulting from heavy alcohol intake. Histologically, alcoholic steatohepatitis (ASH) is characterized by hepatocellular steatosis, inflammation, and fibrosis. Alcohol abstinence is the sine qua non of therapy for AH and, in the milder forms, is prerequisite to clinical recovery. Severe ASH may lead to multi-organ failure such as acute kidney injury and infection, which has a major impact on survival and thus should be closely monitored. Patients with severe ASH have a drastic short-term mortality of up to 40-50%. Specific therapies should be considered for patients with severe ASH at risk of early death. Corticosteroids are the standard of care for patients with severe ASH. When corticosteroids are contraindicated, pentoxifylline may be an alternative option. Steroid responsiveness should be evaluated on the basis of Lille score. Tactically, we should explore novel therapeutic targets to suppress inflammation based on cytokine profiles, promote hepatic regeneration, limit innate immune responses, and restore altered gut mucosal integrity in severe ASH.

Abstract
Alcoholic hepatitis (AH) is an acute hepatic manifestation occurring from heavy alcohol ingestion. Alcoholic steatohepatitis (ASH) is histologically characterized by steatosis, inflammation, and fibrosis in the liver. Despite the wide range of severity at presentation, those with severe ASH (Maddrey’s discriminant function ≥ 32) typically present with fever, jaundice, and abdominal tenderness. Alcohol abstinence is the cornerstone of therapy for AH and, in the milder forms, is sufficient for clinical recovery. Severe ASH may progress to multi-organ failure including acute kidney injury and infection. Thus, infection and renal failure have a major impact on survival and should be closely monitored in patients with severe ASH. Patients with severe ASH have a reported short-term mortality of up to 40%-50%. Severe ASH at risk of early death should be identified by one of the available prognostic scoring systems before considering specific therapies. Corticosteroids are the mainstay of treatment for severe ASH. When corticosteroids are contraindicated, pentoxifylline may be alternatively used. Responsiveness to steroids should be assessed at day 7 and stopping rules based on Lille score should come into action. Strategically, future studies for patients with severe ASH should focus on suppressing inflammation based on cytokine profiles, balancing hepatocellular death and regeneration, limiting activation of the innate immune response, and maintaining gut mucosal integrity.

Abstract
The accurate prognostic stratification of alcoholic hepatitis (AH) is essential for individualized therapeutic decisions. The aim of this study was to develop a new prognostic model to predict liver-related mortality in Asian AH patients. We conducted a hospital-based, retrospective cohort study using 308 patients with AH between 1999 and 2011 (a derivation cohort) and 106 patients with AH between 2005 and 2012 (a validation cohort). The Cox proportional hazards model was constructed to select significant predictors of liver-related death from the derivation cohort. A new prognostic model was internally validated using a bootstrap sampling method. The discriminative performance of this new model was compared with those of other prognostic models using a concordance index in the validation cohort. Bilirubin, prothrombin time, creatinine, potassium at admission, and a spontaneous change in bilirubin levels from day 0 to day 7 (SCBL) were incorporated into a model for AH to grade the severity in an Asian patient cohort (MAGIC). For risk stratification, four risk groups were identified with cutoff scores of 29, 37, and 46 based on the different survival probabilities (P<0.001). In addition, MAGIC showed better discriminative performance for liver-related mortality than any other scoring system in the validation cohort. MAGIC can accurately predict liver-related mortality in Asian patients hospitalized for AH. Therefore, SCBL may help us decide whether patients with AH urgently require corticosteroid treatment.

Abstract
Alcoholic hepatitis (AH) is an acute hepatic inflammation associated with significant morbidity and mortality. Current evidence suggests that the pathogenesis is the end result of the complex interplay between ethanol metabolism, inflammation and innate immunity. Several clinical scoring systems have been derived to predict the clinical outcomes of patients with AH; such as Child-Turcotte-Pugh score, the Maddrey discriminant function, the Lille Model, the model for end stage liver disease scores, and the Glasgow alcoholic hepatitis score. At present, Corticosteroids or pentoxifylline are the current pharmacologic treatment options; though the outcomes from the therapies are poor. Liver transplantation as the treatment of alcoholic hepatitis remains controversial, and in an era of organ shortage current guidelines do not recommend transplantation as the treatment option. Because of the limitations in the therapeutic options, it is no doubt that there is a critical need for the newer and more effective pharmacological agents to treat AH.

Abstract
BACKGROUND Acute hepatitis (AH) in patients with chronic alcoholic liver disease is associated with high mortality. It is therefore vital to identify patients at greatest risk of mortality who may benefit from aggressive intervention. The scoring systems used to assess the severity of AH [Maddrey Discriminant Function (mDF), Child-Pugh Score (CPS) and Glasgow Alcoholic Hepatitis Score (GAHS)] have shown to be useful in determining severity and predicting mortality in these patients. AIM The aim of this study was to compare three scoring systems in predicting 28-day mortality in AH on admission. METHOD AND RESULTS Case notes of 82 patients with AH were reviewed on admission; mDF, CPS, GAHS were calculated and their outcome recorded on day 28. Thirty-six patients (44%) died within 28 days of admission. There was no difference in the age of patients who survived (51.2 ± 11 years) and those who died (52.6 ± 10 years). However, mDF, CPS and GAHS were significantly higher in dead patients (68.7 ± 56.4, 11.8 ± 1.3, 8.6 ± 1.6, respectively) compared to those who survived (36.2 ± 25.9, 10 ± 1.6, 7.6 ± 1.5, respectively) (p < 0.01). Similarly, prothrombin time (PT) was significantly higher in patients who died (23 ± 2 s) compared to those who survived (17.6 ± 0.7 s) (p = 0.007). CONCLUSION There was no difference among three scoring systems in predicting 28-day mortality at the time of admission in patients with AH. In addition, increased PT, gastro-intestinal bleeding and advanced encephalopathy at presentation were associated with high mortality. Furthermore, rise in creatinine from admission increased risk of mortality.

Abstract
Alcoholic hepatitis is a leading cause of liver failure in which the increased production of tumor necrosis factor α (TNFα) plays a critical role in progression of alcoholic liver disease. In the present study, we investigated the effects of cilostazol, a selective inhibitor of type III phosphodiesterase on ethanol-mediated TNFα production in vitro and in vivo, and the effect of cilostazol was compared with that of pentoxifylline, which is currently used in clinical trial. RAW264.7 murine macrophages were pretreated with ethanol in the presence or absence of cilostazol then, stimulated with lipopolysacchride (LPS). Cilostazol significantly suppressed the level of LPS-stimulated TNFα mRNA and protein with a similar degree to that by pentoxifylline. Cilostazol increased the basal AMP-activated protein kinase (AMPK) activity as well as normalized the decreased AMPK by LPS. AICAR, an AMPK activator and db-cAMP also significantly decreased TNFα production in RAW264.7 cells, but cilostazol did not affect the levels of intracellular cAMP and reactive oxygen species (ROS) production. The in vivo effect of cilostazol was examined using ethanol binge drinking (6 g/kg) mice model. TNFα mRNA and protein decreased in liver from ethanol gavaged mice compared to that from control mice. Pretreatment of mice with cilostazol or pentoxifylline further reduced the TNFα production in liver. These results demonstrated that cilostazol effectively decrease the ethanol-mediated TNFα production both in murine macrophage and in liver from binge drinking mice and AMPK may be responsible for the inhibition of TNFα production by cilostazol.

Abstract
Experimental and clinical evidence suggests that cytokeratins (CK), among other physiological functions, are expressed in hepatocytes and can be released in the bloodstream after acute or chronic inflammatory liver injury. Interest in CK in viral and nonviral hepatitis has been rapidly increasing during the last years, especially as they have been proposed as circulating biomarkers of hepatocyte necrosis and apoptosis. In the present review, we sought to summarize and discuss the alterations in circulating CK levels in different form viral and nonviral hepatitis, as well as their potential relation with liver histology. Understanding the mechanisms of hepatitis impact on CK and vice versa is a promising area of research that will positively enhance our understanding of the complexity of acute and chronic inflammatory liver injury.

Abstract
These recommendations provide a data-supported approach. They are based on the following: (i) a formal review and analysis of the recently published world literature on the topic (Medline search); (ii) American College of Physicians Manual for Assessing Health Practices and Designing Practice Guidelines (1); (iii) guideline policies, including the American Association for the Study of Liver Diseases (AASLD) Policy on the development and use of practice guidelines and the AGA Policy Statement on Guidelines (2); and (iv) the experience of the authors in the specified topic. Intended for use by physicians, these recommendations suggest preferred approaches to the diagnostic, therapeutic, and preventive aspects of care. They are intended to be flexible, in contrast to the standards of care, which are inflexible policies to be followed in every case. Specific recommendations are based on relevant published information. To more fully characterize the quality of evidence supporting the recommendations, the Practice Guideline Committee of the AASLD requires a Class (reflecting the benefit vs. risk) and Level (assessing the strength or certainty) of Evidence to be assigned and reported with each recommendation (Table 1, adapted from the American College of Cardiology and the American Heart Association Practice Guidelines) (3,4).

Abstract
OBJECTIVES Prognostic stratification of patients with alcoholic hepatitis (AH) may improve the clinical management and facilitate clinical trials. We aimed at developing a scoring system capable of providing prognostic stratification of patients with AH. METHODS Patients with biopsy-proven AH were prospectively included between 2000 and 2006. The biochemical, clinical, portal hemodynamic and histological parameters were evaluated. A Cox regression model was used for univariate and multivariate analyses. A predictive score was built using variables obtained at admission identified in the multivariate analysis. The resulting score was validated in an independent prospective cohort. RESULTS In total, 103 patients with biopsy-proven AH were included in the study cohort. Age, serum bilirubin, serum creatinine, and international normalized ratio (INR) independently predicted 90-day mortality. We generated the Age, serum Bilirubin, INR, and serum Creatinine (ABIC) score: (age x 0.1) + (serum bilirubin x 0.08) + (serum creatinine x 0.3) + (INR x 0.8). The area under the curve (AUC) was 0.82. Using the Kaplan-Meier analysis with the cutoff values of 6.71 and 9.0, we identified patients with low, intermediate, and high risk of death at 90 days (100%, 70%, and 25% of survival rate, respectively). Using the same cutoff values, the ABIC score also stratified patients according to their risk of death at 1 yr. These results were validated by a confirmatory cohort (N = 80). CONCLUSIONS The ABIC score is a new tool that allows the stratification of risk of death in patients with AH at 90 days and 1 yr. This score can help improve the management of these patients and also help to perform clinical trials.

Abstract
Chronic alcohol drinking has been associated with the development of a number of abnormalities, including neuron-behavioral disorders, liver, pancreas, and heart-related diseases and inflammation and immune disorders. Because diverse mechanisms are involved in the development of these disorders, the commonly used receptor- or enzyme-specific drugs do not provide comprehensive protection against the adverse effects of alcoholism. This study describes possible therapeutic potency of puerarin (PU) from kudzu root, polyenylphosphatidylcholine from soy (SPCh), and curcumin (CU) from turmeric against alcohol's addiction-related and inflammatory-related abnormalities in alcohol-preferring P rats receiving free choice water and 15% ethanol in water. P-rats were fed once daily either the vehicle (for control) or different doses of PU, SPCh, CU, PU + SPCh, or PU + CU. The rats were divided in two groups: one received water alone, and the other free choice water and ethanol. Four rats from each group were fitted with electroencephalogram (EEG) electrodes for EEG recording. After 70 days of alcohol drinking, alcohol was withdrawn for 2 weeks, and the withdrawal symptoms were assessed. This study showed that alcohol drinking for 70 days (1) caused liver inflammation characterized by elevated tumor necrosis factor-alpha, interleukin-1beta, and matrix metalloproteinase-9 expression and (2) dysregulated lipopolysaccharide (LPS)-induced pleurisy. Alcohol withdrawal after 70 days of drinking generated severe withdrawal symptoms including seizure-type EEG activity. PU suppressed the addiction-mediated abnormalities but did not affect the inflammation-related abnormalities, while SPCh or CU suppressed only the inflammation-related abnormalities in alcohol-drinking rats subjected to LPS-induced pleurisy. A combination of PU with SPCh or CU suppressed both the addiction-related and inflammation-related abnormalities of alcohol drinking. Therefore, a mixture consisting of PU and either SPCh or CU may provide alternative therapy for alcohol-related disorders.

Abstract
The treatment of alcoholic hepatitis remains one of the most debated topics in medicine and a field of continued research. In this review, we discuss the evolution of scoring systems, including the recent development of the Glasgow alcoholic hepatitis score, role of liver biopsy and current treatment interventions. Studies of treatment interventions with glucocorticoids, pentoxifylline, infliximab, s-adenosyl-methionine, and colchicine are reviewed with discussion on quality. Glucocorticoids currently remain the mainstay of treatment for severe alcoholic hepatitis.

Abstract
PURPOSE OF REVIEW To apprise the reader of advances in 2005 in the epidemiology, pathogenesis, prognosis and treatment of alcoholic liver disease. Alcohol use has declined in developed countries, but the opposite is true elsewhere; alcoholic liver disease is a considerable burden worldwide. RECENT FINDINGS Genetic mechanisms for alcoholic liver disease are being discovered in addition to aggravating cofactors, such as hepatitis C, obesity and iron overload, and ameliorating ones, like coffee and tea drinking. The involvement of the innate immune system and the mechanisms of apoptosis in alcoholic liver disease are better appreciated, especially the emerging role of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). Steroid use and nutrition for alcoholic hepatitis are being refined, and the validity of the model for end-stage liver disease (MELD) score in predicting the outcome of alcoholic liver disease is upheld. Recidivism after liver transplantation for alcoholic liver disease adversely impacts long-term survival. SUMMARY Inroads are being made into the genetics of alcoholic liver disease and new phenomena are being uncovered in its pathogenesis, but safe and effective therapies for both alcoholic hepatitis and alcoholic cirrhosis are still wanting.
