Background
Hepatorenal syndrome (HRS) is a common complication among patients with cirrhosis, primarily attributable to vasodilation of renal vessels. Vasoactive agents are commonly used to treat HRS. The present network meta-analysis compares the vasoactive agents used in HRS.
Methods
We searched electronic databases for appropriate randomized controlled clinical trials in patients with HRS, comparing active interventions with either placebo or standard of care. The primary outcome was complete HRS reversal; secondary outcomes included partial HRS reversal, mortality, adverse events, and cardiovascular adverse events. The data were pooled using a random effects model. We also carried out direct comparisons for the primary outcome with trial sequential analysis.
Results
A total of 16 studies were included in the systematic review. Rates of complete HRS reversal were significantly higher with terlipressin and noradrenaline combined with albumin than with placebo (OR 6.65, 95% CI: 2.08–21.31 and 6.81, 95% CI: 1.87–24.83, respectively). No significant differences were observed in terms of mortality, partial HRS reversal, or adverse events for any of the interventions. However, cardiovascular adverse events were significantly higher with continuous-infusion terlipressin/albumin (OR 7.07, 95% CI: 1.23–40.62), bolus terlipressin/albumin (OR 7.39, 95% CI: 1.89, 28.94), octreotide/midodrine/albumin (OR 9.85, 95% CI: 1.1, 88.1), and noradrenaline/albumin (OR 15.24, 95% CI: 2.1, 112.6) than with albumin alone. Trial sequential analyses revealed adequate evidence to conclude that terlipressin combined with albumin was effective in achieving complete HRS reversal.
Discussion
Terlipressin combined with albumin shows strong evidence of improving short-term survival in patients with type 1 but not type 2 HRS. Through indirect comparison, noradrenaline with albumin was also associated with significant benefits in terms of HRS reversal.
