RESUMO

BACKGROUND: Liver transplantation (LT) can significantly improve mortality for severe alcoholic hepatitis (AH). However, this practice remains controversial. Our aim is to report the findings from our institution regarding outcomes for LT in severe AH and to discuss the results of a pilot program for discharging selected patients with close follow-up, in order to demonstrate sustained outpatient sobriety before listing. METHODS: Patient records were reviewed retrospectively from January 1, 2015 to January 17, 2018. The primary outcomes were patient and graft survival after LT. Secondary outcomes included relapse rates after LT, survival for those not transplanted, and reasons for denial among those not approved for transplant listing. RESULTS: A total of 18 patients with severe AH were considered for LT, of which 10 were transplanted and 8 were either denied transplantation or died before completing the evaluation. Patient and graft survival rates were 100% among those transplanted, and only 1 of the 10 patients (10%) returned to harmful drinking. In comparison, 6 of 8 (75%) of patients not transplanted died. Among the 10 patients transplanted, 4 were initially not approved for listing and were discharged with close follow-up, to demonstrate outpatient sobriety. All 4 of those patients demonstrated short-term abstinence and ultimately underwent transplantation, with no instances of relapse post-LT. CONCLUSIONS: Liver transplantation for AH can achieve excellent outcomes with low rates of relapse. Carefully selected patients can be discharged with close monitoring to demonstrate commitment to outpatient sobriety prior to transplant listing.

RESUMO

BACKGROUND: Non-alcoholic steatohepatitis (NASH) and resultant liver fibrosis is a major health problem without approved pharmacotherapy. Pre-clinical results of GR-MD-02, a galectin-3 inhibitor, suggested potential efficacy in NASH with advanced fibrosis/cirrhosis and prompted initiation of a clinical development programme in NASH with advanced fibrosis. AIM: To evaluate the safety, pharmacokinetics and exploratory pharmacodynamic markers of GR-MD-02 in subjects having NASH with bridging fibrosis. METHODS: The GT-020 study was a first-in-human, sequential dose-ranging, placebo controlled, double-blinded study with the primary objective to assess the safety, tolerability and dose limiting toxicity of GR-MD-02, in subjects with biopsy-proven NASH with advanced fibrosis (Brunt stage 3). The secondary objectives were to characterise first-dose and multiple-dose pharmacokinetic profiles and to evaluate changes in potential serum biomarkers and liver stiffness as assessed by FibroScan. RESULTS: GR-MD-02 single and three weekly repeated of 2, 4 and 8 mg/kg revealed no meaningful clinical differences in treatment emergent adverse events, vital signs, electrocardiographic findings or laboratory tests. Pharmokinetic parameters showed a dose-dependent relationship with evidence of drug accumulation following 8 mg/kg (~twofold). CONCLUSIONS: GR-MD-02 doses were in the upper range of the targeted therapeutic dose determined from pre-clinical data and were safe and well tolerated with evidence of a pharmacodynamic effect. These results provide support for a Phase 2 development programme in advanced fibrosis due to NASH.

RESUMO

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) can lead to non-alcoholic steatohepatitis (NASH) and cirrhosis. Fibrosis predicts worse outcomes and mortality. New treatments targeting fibrosis are being investigated to reverse disease progression. AIM: To review the new pipeline therapeutic agents targeting fibrosis in NASH patients, with particular focus on clinical trials in which reversing fibrosis and portal hypertension are the primary outcomes. METHODS: The literature was searched in PubMed between January 2000 and January 2016 using search terms non-alcoholic fatty liver disease and NASH, with filters of 'English language'. We focused on fibrosis improvement as the key outcome. We also searched the ClinicalTrials.gov for promising agents that target fibrosis in NASH patients. RESULTS: Significant advances have been made on approaches targeting fibrosis in NASH patients. Many therapeutic agents are already in development, some of which have shown promising results in preclinical and phase I studies. Novel therapies have entered phase II and III studies targeting fibrosis reversal and/or improvement in portal hypertension. Innovative studies have also started looking into combining these agents, aiming at different mechanisms to maximise therapeutic outcomes. We found five clinical trials in phase II and one in phase III focusing on fibrosis in NASH patients as key outcomes. One of the phase II trials is using combination therapy to target fibrosis. CONCLUSIONS: Ongoing research studies are already investigating new pathways aimed at reversing fibrosis in NASH patients. Novel therapeutic agents are in development and are expected to offer unique options to NASH patients with advanced fibrosis.

RESUMO

IFNL4 is linked to hepatitis C virus treatment response and type III interferons (IFNs). We studied the functional associations among hepatic expressions of IFNs and IFN-stimulated genes (ISGs), and treatment response to peginterferon and ribavirin. Type I IFNs (IFNA1, IFNB1), type II (IFNG), type III (IFNL1, IFNL2/3), IFNL4 and ISG hepatic expressions were measured by qPCR from in 65 chronic hepatitis C (CHC) patients whose IFNL4-associated rs368234815 and IFNL3-associated rs12989760 genotype were determined. There was a robust correlation of hepatic expression within type I and type III IFNs and between type III IFNs and IFNL4 but no correlation between other IFN types. Expression of ISGs correlated with type III IFNs and IFNL4 but not with type I IFNs. Levels of ISGs and IFNL2/3 mRNAs were lower in IFNL3 rs12979860 CC patients compared with non-CC patients, and in treatment responders, compared with nonresponders. IFNL4-ΔG genotype was associated with high ISG levels and nonresponse. Hepatic levels of ISGs in CHC are associated with IFNL2/3 and IFNL4 expression, suggesting that IFNLs, not other types of IFNs, drive ISG expression. Hepatic IFNL2/3 expression is functionally linked to IFNL4 and IFNL3 polymorphisms, potentially explaining the tight association among ISG expression and treatment response.
