Over a 6-month period, treatment with rifaximin maintained remission from hepatic encephalopathy more effectively than did placebo. Rifaximin treatment also significantly reduced the risk of hospitalization involving hepatic encephalopathy. (ClinicalTrials.gov number, NCT00298038.)

Terlipressin plus albumin was associated with greater improvement in renal function vs albumin alone in patients with cirrhosis and HRS-1. Patients had similar rates of HRS reversal with terlipressin as they did with albumin. ClinicalTrials.gov no: NCT01143246.

Long-term treatment (≥24 mo) with rifaximin (550 mg, twice daily) appears to provide a continued reduction in the rate of HE-related and all-cause hospitalization, without an increased rate of adverse events. ClinicalTrials.gov number: NCT00686920.

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).

Among AIH patients, Hispanics had the highest prevalence of cirrhosis, and Asians had poorer survival outcomes. Race/ethnicity-specific disparities in AIH epidemiology may reflect underlying genetic differences, contributing to variations in disease severity, response to therapy, and overall mortality.
