SummaryBackgroundThe goal of hepatorenal syndrome type 1 (HRS‐1) treatment is to improve renal function. Terlipressin, a synthetic vasopressin analogue, is a systemic vasoconstrictor used for the treatment of HRS‐1, where it is available.AimTo compare the efficacy of terlipressin plus albumin vs. placebo plus albumin in patients with HRS‐1.MethodsPooled patient‐level data from two large phase 3, randomised, placebo‐controlled studies were analysed for HRS reversal [serum creatinine (SCr) value ≤133 μmol/L], 90‐day survival, need for renal replacement therapy and predictors of HRS reversal. Patients received intravenous terlipressin 1–2 mg every 6 hours plus albumin or placebo plus albumin up to 14 days.ResultsThe pooled analysis comprised 308 patients (terlipressin: n = 153; placebo: n = 155). HRS reversal was significantly more frequent with terlipressin vs. placebo (27% vs. 14%; P = 0.004). Terlipressin was associated with a more significant improvement in renal function from baseline until end of treatment, with a mean between‐group difference in SCr concentration of −53.0 μmol/L (P < 0.0001). Lower SCr, lower mean arterial pressure and lower total bilirubin and absence of known precipitating factors for HRS were independent predictors of HRS reversal and longer survival in terlipressin‐treated patients.ConclusionsTerlipressin plus albumin resulted in a significantly higher rate of HRS reversal vs. albumin alone in patients with HRS‐1. Terlipressin treatment is associated with improved renal function. (ClinicalTrials.gov identifier: OT‐0401, NCT00089570; REVERSE, NCT01143246).

Goals/Background: Data on acute variceal hemorrhage (AVH) in the United States is limited and the best method to stratify risk is not clear. Taking advantage of a prospective US cohort study, we aimed to (1) describe clinical outcomes of AVH and their predictors; (2) compare predictors of 6-week mortality. Study: Prospective 15-center US cohort of patients with cirrhosis presenting with endoscopically proven AVH, all of whom received antibiotics, vapreotide (a somatostain analog) infusion and endoscopic band ligation. Patients were enrolled between August 2006 and April 2008. Primary outcome was 6-week mortality. Secondary outcome was 5-day treatment failure. The prognostic value of Child-Turcotte-Pugh (CTP) class, Model for End-stage Liver Disease (MELD) score and a recent recalibrated MELD were compared. Results: Seventy eligible patient were enrolled; 18 (26%) patients died within 6-weeks of index bleed. Demographic, clinical, and laboratory data were compared between survivors and nonsurvivors. Multivariate models showed that admission CTP or the MELD score (separately) were independent predictors of survival. The discriminative values of CTP (area under receiver operating characteristic: 0.75) and MELD (area under receiver operating characteristic: 0.79) were good and not significantly different (P=0.27). However, calibration (correlation between observed and predicted mortality) test was significantly better for CTP than for MELD, with the recently described recalibrated MELD model having the worst agreement. Predicted mortality for CTP-A was <10%, CTP-B 10% to 30%; and CTP-C >33%. Conclusions: AVH mortality of 26% in the United States is in the upper range limit compared with recent series but may be due to inclusion of patients with more advanced cirrhosis. CTP score has the best overall performance in the prediction of 6-week mortality and is best at stratifying risk.

In smaller single‐center studies, patients with cirrhosis are at a high readmission risk, but a multicenter perspective study is lacking. We evaluated the determinants of 3‐month readmissions among inpatients with cirrhosis using the prospective 14‐center North American Consortium for the Study of End‐Stage Liver Disease cohort. Patients with cirrhosis hospitalized for nonelective indications provided consent and were followed for 3 months postdischarge. The number of 3‐month readmissions and their determinants on index admission and discharge were calculated. We used multivariable logistic regression for all readmissions and for hepatic encephalopathy (HE), renal/metabolic, and infection‐related readmissions. A score was developed using admission/discharge variables for the total sample, which was validated on a random half of the total population. Of the 1353 patients enrolled, 1177 were eligible on discharge and 1013 had 3‐month outcomes. Readmissions occurred in 53% (n = 535; 316 with one, 219 with two or more), with consistent rates across sites. The leading causes were liver‐related (n = 333; HE, renal/metabolic, and infections). Patients with cirrhosis and with worse Model for End‐Stage Liver Disease score or diabetes, those taking prophylactic antibiotics, and those with prior HE were more likely to be readmitted. The admission model included Model for End‐Stage Liver Disease and diabetes (c‐statistic = 0.64, after split‐validation 0.65). The discharge model included Model for End‐Stage Liver Disease, proton pump inhibitor use, and lower length of stay (c‐statistic = 0.65, after split‐validation 0.70). Thirty percent of readmissions could not be predicted. Patients with liver‐related readmissions consistently had index‐stay nosocomial infections as a predictor for HE, renal/metabolic, and infection‐associated readmissions (odds ratio = 1.9‐3.0). Conclusions: Three‐month readmissions occurred in about half of discharged patients with cirrhosis, which were associated with cirrhosis severity, diabetes, and nosocomial infections; close monitoring of patients with advanced cirrhosis and prevention of nosocomial infections could reduce this burden.

Interferon (IFN)‐free regimens are needed to treat hepatitis C virus (HCV) infection. Combined simeprevir (SMV) and sofosbuvir (SOF) with or without ribavirin (RBV) results in high sustained virological response (SVR) rates along with minimal adverse events (AEs) in patients with hepatitis C genotype 1 (HCV GT1). The aim of this study was to report on the virological response, safety, and tolerability of SOF and SMV with or without RBV in compensated and decompensated patients with cirrhosis with HCV GT1 infection. Patients treated with standardized clinical protocol utilizing SMV+SOF with or without RBV at three transplant centers were retrospectively reviewed. A total of 119 patients (61% male, 87% white, 69% subtype 1a, 30% Child‐Pugh‐Turcott [CPT]‐B liver cirrhosis [LC], and 82% were treatment experienced) received treatment and were followed for a median of 38 weeks (range, 12‐58). Sustained virological response (SVR) at week 12 (SVR12) was achieved in 78% (92 of 118) of patients (95% confidence interval: 69‐85). Lower pretreatment Model for End Stage Liver Disease (MELD) score was a predictor of SVR12 ( P = 0.018). Baseline viral load, previous treatment status, RBV use, or GT1 subtype did not impact SVR 12. The majority of patients with SVR12 showed stability or improvement in MELD score. Treatment was very well tolerated with mild degrees of AEs. Conclusions: The regimen of SMV+SOF with or without RBV for 12 weeks was very well tolerated and resulted in high SVR12 rates (78%) in HCV GT1 patients with LC. SVR12 was inversely related to pretreatment MELD. SVR12 had favorable short‐term impact on MELD score. Long‐term impact on disease stability is yet to be determined. Longer treatment duration or the use of different regimen may still be needed in this population. (H epatology 2015;62:1004‐1012)

Treatment with an all‐oral interferon‐free antiviral regimen using simeprevir and sofosbuvir with or without ribavirin (RBV) for 12 weeks resulted in high sustained virologic response (SVR) rates along with minimal adverse events in non–liver transplant (LT) patients with hepatitis C virus (HCV) genotype 1 infection. This is the first multicenter report on the efficacy, safety, and tolerability of this regimen in LT recipients. A total of 123 patients (76% male, 74% white, 60% genotype 1a, 30% METAVIR F3‐F4, 4% decompensation, 11% cholestatic recurrence, 7% had kidney transplant, and 82% previously failed pegylated interferon/RBV‐based regimens) received treatment and were followed for a median of 30 weeks (range 12‐53 weeks). The median time from LT to treatment was 32 months (range 2‐317 months). Tacrolimus was the primary immunosuppression in 91% of patients. Minimal immunosuppression dose adjustments were required. An SVR 12 weeks after treatment completion (SVR12) was achieved in 90% of patients (95% confidence interval 84%‐96%). In patients with genotype 1a infection, the SVR12 rate was significantly lower in those with METAVIR F3‐F4 (71%) compared to those with F0‐F2 (91%). Half of the patients achieved undetected HCV RNA at treatment week 4, and their SVR12 rate was significantly higher (96%) compared to those with detectable HCV RNA (83%). Treatment was very well tolerated with mild degrees of adverse events, except for one death possibly due to drug‐induced lung injury. In the 25 patients who received RBV, 72% developed anemia requiring intervention. Conclusion : An all‐oral interferon‐free antiviral regimen using simeprevir and sofosbuvir with or without RBV for 12 weeks was very well tolerated and resulted in excellent SVR12 rates in LT recipients with HCV genotype 1 infection.

AbstractSarcopenia, or loss of skeletal muscle mass, is associated with increased mortality and morbidity in liver transplant (LT) candidates. Six‐minute walk distance (6MWD) and health‐related quality of life (HRQOL) as assessed by short form 36 scores (SF‐36) also impact clinical outcomes in these patients. This study explored the relationship between the sarcopenia, 6MWD, and HRQOL in LT candidates. Sarcopenia was evaluated based on skeletal muscle mass index (SMI) quantified from abdominal computed tomography. Patients were followed until death, removal from the wait list or the end of the study period. Two hundred and thirteen patients listed for LT were included. The mean SMI, 6MWD and mean gait speed were 54.3 ± 9.7, 370.5 m and 1 m/s, respectively. Sarcopenia was noted in 22.2% of LT candidates. There was no correlation between sarcopenia, 6MWD, and SF‐36 scores. The 6MWD, but not sarcopenia, was an independent predictor of mortality (hazard ratio = 2.1 [0.9–4.7]). In summary, sarcopenia did not emerge as a significant predictor of waitlist mortality and also failed to correlate with either functional capacity or HRQOL in LT candidates. In patients with ESLD awaiting LT, 6MWD appears to be a more useful prognostic indicator than the presence of sarcopenia.
