Megjegyzések:Although mortality due to acute alcoholic hepatitis (AH) correlates with Model for End-Stage Liver Disease (MELD) scores, biomarkers are critically needed to manage this disease. Increases in inflammatory markers and macrophage activation are associated with acute AH and could be potential biomarkers of clinical events and/or mortality. We enrolled 89 clinically diagnosed AH patients in four US academic medical centers. Plasma from AH patients had a significant increase in gut microbial translocation indicators (endotoxin, bacterial 16S ribosomal DNA) and host response indicators (soluble cluster of differentiation 14 [sCD14] and lipopolysaccharide binding protein [LBP]) compared to controls. Patient MELD score and Glasgow Alcoholic Hepatitis score (GAHS) correlated with endotoxin levels. AH patients also had a significant increase in high mobility group protein 1 (HMGB1), a sterile danger signal molecule, and osteopontin (OPN), a multifunctional phosphoprotein involved in neutrophil activation, compared to controls. Increased levels of OPN positively correlated with increasing MELD score, GAHS, and LBP levels. Consistent with these results, AH patients had significantly increased circulating levels of macrophage activation (sCD163 and sCD206) markers compared to healthy controls, and sCD163 and sCD206 significantly and positively correlated with OPN, HMGB1, and LBP levels as well as with MELD score and GAHS. These findings indicate a connection between microbial translocation, immune cell activation, and AH severity. Plasma sCD14, OPN, sCD163, and sCD206 levels were significantly higher in nonsurvivors than survivors. In multivariate regression models, we identified sCD14, sCD163, and OPN as independent predictors of 90-day mortality, infection, and organ failure development, respectively. Conclusion: Our study suggests that sCD14, LBP, OPN, sCD163, and sCD206 are biomarkers to indicate severity and predict clinical outcomes in AH.

Megjegyzések:Background & aims: Patients with severe alcohol-associated hepatitis (AH) have high mortality. Corticosteroids improve survival only for 30 days. We targeted inflammation, cellular injury and gut leakiness in a randomized clinical trial comparing combination therapy to corticosteroids on 180-day survival. Approach & results: Subjects with a clinical diagnosis of severe AH (MELD>20, MDF>32) were randomized to receive methylprednisolone (28 days) (PRED) or a combination of anakinra (14 days) plus pentoxifylline (28 days) plus zinc (180 days) (COMB). The primary endpoint was survival at 180 days. The study was designed in 2013, initiated in October 2014 and completed in March 2018. Five hundred (500) patients were screened to randomize 104 subjects with a clinical diagnosis of AH with a Model for End Stage Liver Disease (MELD) score > 20. Fifty-three (53) patients were randomized into the COMB and fifty (50) to the PRED treatment; one dropped out of the study before randomization. The mean age was 45.3?10.4 years. 60.6% were males, 92.3% white, mean MELD 25.7?3.9. Kaplan-Meier survival estimate at 180-day was 67.9% in COMB and 56% in PRED (HR=0.69; p=0.3001). Survival curves separated by 90 days (COMB: 69.8%; PRED: 58.0%; HR=0.69, p=0.28). Survival at 28 days was similar between the COMB (83.4%) and PRED groups (81.2%) (HR=0.91, p=0.85). There were no unexpected serious adverse events and the incidence of infection was comparable between groups. MELD 20-25 and MELD >26 strata showed non-significant treatment effects in favor of COMB. Conclusions: A combination of anakinra, pentoxifylline plus zinc provides similar survival benefits compared to corticosteroid therapy in severe AH.

Cím:A novel score of IL-13 and age predicts 90-day mortality in severe alcohol-associated hepatitis : a multicenter plasma biomarker analysis / David Tornai, Mack Mitchell, Craig J.

Megjegyzések:Background: Severe alcoholic hepatitis (AH) has a high short-term mortality rate. The Model for End-Stage Liver Disease (MELD) assesses disease severity and mortality, however, it is not specific for AH. We screened plasma samples from severe AH patients for biomarkers of multiple pathological processes and identified predictors of short-term mortality. Methods: Plasma was collected at baseline from 85 severe AH patients (MELD?20, MDF?32) enrolled in the DASH clinical trial (investigating IL-1receptor antagonist+pentoxifylline+zinc vs. methylprednisolone+placebo). Samples were analyzed for 43 biomarkers and the markers' association with 28 and 90-day mortality was assessed. Results: Thirty-one (36.5%) patients died during the 90-day follow-up with similar ratios in the treatment groups. Eight biomarkers showed association with mortality. Interleukin-6, IL-22, IFN-?2, sTNF-R1, lipocalin-2 and ?-fetoprotein levels were associated with 28-day, while IL-6, IL-13 and endotoxin levels with 90-day mortality. In multivariable Cox regression, encephalopathy, lipocalin-2 and ?-fetoprotein levels were independent predictors of 28-day mortality and IL-6, IL-13, INR levels and age were independent predictors of 90-day mortality. The combination of IL-13 and age had superior performance predicting 90-day mortality compared to MELD in the total cohort and the individual treatment groups. Conclusions: We identified predictors of short-term mortality in a cohort exclusively involving severe AH patients. We created a composite score of IL-13 and age that predicts 90-day mortality regardless of treatment type with a performance superior to MELD in severe AH.
