Project description:Alcoholic hepatitis (AH) is a clinical syndrome characterized by jaundice and progressive inflammatory liver injury in patients with a history of prolonged periods of excess alcohol consumption and recent heavy alcohol abuse. Severe AH is a life-threatening form of alcohol-associated liver disease with a high short-term mortality rate around 30-50% at one month from the initial presentation. A large number of pro-inflammatory mediators, metabolic pathways, transcriptional factors and epigenetic factors have been suggested to be associated with the development and progression of AH. Several factors may contribute to liver failure and mortality in patients with severe AH including hepatocyte death, inflammation, and impaired liver regeneration. Although the pathogeneses of AH have been extensively investigated and many therapeutic targets have been identified over the last five decades, no new drugs for AH have been successfully developed. In this review, we discuss interleukin-22 (IL-22) biology and its roles of anti-apoptosis, anti-fibrosis, anti-oxidation, anti-bacterial infection and regenerative stimulation in protecting against liver injury in many preclinical models including several recently developed models such as chronic-plus-binge ethanol feeding, acute-on-chronic liver failure, C-X-C motif chemokine ligand 1 plus high-fat diet-induced nonalcoholic steatohepatitis. Finally, clinical trials of IL-22 for the treatment of AH are also discussed, which showed some promising benefits for AH patients.

Project description:Excessive alcohol consumption is responsible for approximately 50% of all deaths due to cirrhosis. Although the duration and amount of alcohol consumption are the primary factors responsible for the liver injury caused by consuming alcohol, the pathogenesis of the 3 stages of alcohol-associated liver disease (ALD)-fatty liver, alcoholic hepatitis (AH), and cirrhosis- is likely multifactorial. Preexisting obesity, dysbiosis of the gut microbiome, activation of proinflammatory cytokines, and genetic factors can all contribute to the risk of developing ALD. The cornerstone of therapy for all stages of ALD is abstinence from drinking alcoholic beverages. Severe AH, defined by a Maddrey discriminant function greater than 32, warrants additional therapy. The results of multiple studies evaluating the use of glucocorticoids in the treatment of severe AH led to guidelines from international societies that recommend glucocorticoid therapy in patients with severe AH without active infection. Liver transplantation provides an effective treatment option for patients who fail glucocorticoid therapy. Recent advances in understanding the pathogenesis of AH have led to the investigation of potential therapies directed at preventing the development of steatosis, inhibiting the innate immune response, modifying the gut microbiome, and stimulating liver regeneration.

Project description:IntroductionDespite the significant morbidity and mortality associated with alcoholic hepatitis, a consensus or generally accepted therapeutic strategy has not yet been reached. The purpose of this analysis was to evaluate the effects of corticosteroids and pentoxifylline on short-term mortality, incidence of hepatorenal syndrome, and sepsis in patients with severe alcoholic hepatitis.Materials and methodsWe conducted a comprehensive search of the Cochrane library, PUBMED, Scopus, EMBASE, and published proceedings from major hepatology and gastrointestinal meetings from January 1970 to June 2015. All relevant articles irrespective of language, year of publication, type of publication, or publication status were included. Two independent reviewers extracted data and scored publications; a third investigator adjudicated discrepancies. The κ scores were measured to assess the agreement between the 2 initial reviewers. The review and meta-analyses were performed following the recommendations of The Cochrane Collaboration. Conventional meta-analysis and Trial sequential analysis were performed. GRADEpro version 3.6 was used to appraise the quality of epidemiologic evidence.ResultsA total of 14 studies satisfied inclusion criteria comparing corticosteroids, pentoxifylline, or placebo. Compared with placebo, corticosteroids reduced 28-day mortality (RR=0.53; 95% CI, 0.33-0.84; P=0.006). There was no statistically significant difference in short-term mortality between pentoxifylline and placebo (RR=0.74; 95% CI, 0.46-1.18; P=0.21). Neither corticosteroids nor pentoxifylline impacted the incidence of hepatorenal syndrome or sepsis. Trial sequential analysis confirmed the results of our conventional meta-analysis.Conclusions and relevanceCorticosteroids demonstrated a decrease in 28-day mortality in patients with severe alcoholic hepatitis. The evidence from this study is insufficient to support any recommendations regarding the mortality benefit of pentoxifylline in severe alcoholic hepatitis.

Project description:Despite significant scientific knowledge in the field of cancer immunology, therapeutic strategies using cancer vaccines to generate anti-tumor immunity have historically resulted in only modest clinical benefit. Disappointing results from prior cancer vaccine trials are likely due to multifactorial causes. Perhaps the most important is the role of inherent tumor-induced immune suppression and enhanced immunologic tolerance. Current research directed toward understanding the mechanisms of immunologic tolerance has led to the development of promising therapeutic immune regulatory antibodies that inhibit immunologic checkpoints and subsequently enhance immunologic anti-tumor activity. This review discusses the prior challenges associated with cancer vaccines and describes how, by breaking immune inhibition and facilitating immune stimulation, immune regulatory antibodies show great promise in the treatment of a variety of tumors.

Project description:The natural history of moderate alcoholic hepatitis (AH) is not well known. It is a frequent disease with a probable underestimated incidence compared with its severe form. Among the different prognostic scores predicting short-term mortality in AH, MELD seems to be the most accurate. The mortality of moderate AH is 3% to 7% in the short to medium term and 13% to 20% at 1 year, mainly because of liver-related complications, including severe infections. Long-term abstinence is the main goal of the treatment. There is still need for the development of new therapies for AH, including the less severe forms.

Project description:It was hypothesized that the severe inflammatory liver injury caused by alcoholic hepatitis (AH) would yield a unique peptidome profile in human patient plasma, and degraded fragments (degradome) of hepatic and extracelluar proteomes would change between AH patient groups defined by MELD scores. Following addition of iRT standards (Biognosys), the low molecular weight proteome (peptidome) was isolated from 100uL patient K3EDTA plasma using TCA precipitation, cleaned up by solid phase extraction on Waters Oasis HLB 96-well plates, and peptide concentrations estimated by A205nm on a Nanodrop. Peptides were separated by nanoUPLC on Proxeon 1000 thermostated at 50oC prior to nanoelectrospray into an Orbitrap ELITE. High resolution MS1 (240,000) were collected in the FT and MS2 were collected by ITMS. Data were analyzed by PEAKS Studio for de novo database analysis and PTM imputation. TIC-normalized XIC data were used for statistical analyses.

Project description:Hepatitis B is one of the leading causes of liver cancer worldwide and unfortunately the number of people affected with hepatitis B virus (HBV) infection is still on the rise. Although the HBV has been known to cause fatal illness since decades but the population effected by this lethal virus have still only a few options for its management. The major treatment strategies include interferons and nucleos(t)ide analogues. These agents have so far produced unsatisfactory results in terms of complete virus eradication. Interferons cannot be used for long term therapy because of their potential side effects. Prolong treatment with nucleos(t)ide analogues has also been reported to cause serious side effects besides the increasing resistance by the virus. The need for new innovative solutions for treatment of HBV has been realized by global research institutes and pharmaceutical industry. Present review focuses in detail on the new ideas that are being transformed into therapeutic tools for use as future therapies in HBV infection. Modern drug designing and screening methods have made the drug discovery process shorter and more reliable. HBV therapeutics will take a new turn in coming years owing to these intelligent drug designing and screening methods. Future therapy of HBV is aiming to include the use of vaccines (both prophylactic and therapeutic), immunomodulators such as antibodies, non-nucleoside antivirals such as RNAi and inhibitors of viral life cycle.
