Noradrenaline is as Effective as Terlipressin in Hepatorenal Syndrome Type 1: A Prospective, Randomized Trial.

OBJECTIVES: Hepatorenal syndrome (HRS) is a functional renal failure occurring in end stage liver disease, which is associated with poor prognosis. Terlipressin has been shown to be effective in treatment of HRS. More recently, it was suggested that noradrenaline, an alpha-adrenergic drug may be also effective in HRS. We aimed to compare the efficacy of noradrenaline versus terlipressin in treatment of HRS type 1.

METHODS: Consecutive patients with cirrhosis and HRS type 1 were enrolled and randomised into 2 groups- Group A received intravenous noradrenaline infusion (0.5-3 mg/h) and group B received intravenous terlipressin (0.5-2 mg/6h) for 2 weeks. Intravenous albumin (20 g/day) was given to both groups.

RESULTS: Out of 55 cirrhotics screened, 41 were randomised into group A (n=21) or group B (n=20). Baseline characteristics of the two groups were similar. HRS reversal was seen in 47.6%(10/21) patients in group A, and 45% (9/20) patients in group B (p=1.00). In both groups, there was a significant decrease in serum creatinine from baseline (group A- 3.1±1.4 mg/dl to 2.2±1.3 mg/dl, p=0.028; group B- 3.4±1.6 mg/dl to 2.3±1.3 mg/dl, p=0.035). Both the groups showed a significant increase in mean arterial pressure (group A- 77.3±8.6 mmHg to 103.4±8.3 mmHg, p=0.0001; group B- 76.8±11.6 mmHg to 100±9.4 mmHg, p=0.0001). Noradrenaline was associated with fewer adverse events and was significantly cheaper than terlipressin. Lower baseline MELD score was an independent predictor of response to treatment.

CONCLUSIONS: Noradrenaline is as effective and safe as terlipressin in the treatment of HRS type 1.
