Summary

Hepatorenal syndrome (HRS) is defined as a functional renal failure in a patient with chronic liver disease, or liver cirrhosis.The splanchnic circulation undergoes severe vasodilation, as a result of portal hypertension, causing an underfilling of systemic arteries.This results in intense renal vasoconstriction and functional renal failure. The best treatment options for HRS I would be a drug which has renal vasodilator property and additional splanchnic vasoconstriction. An increase in circulating blood volume would be of additional benefit. Currently Terlipressin is considered superior to other drugs in the management of HRS I. Other drugs in use are Noradrenaline and Midodrine. Albumin is added to these drugs in order to expand plasma volume. Terlipressin, a Vasopressin analog, has agonistic activity at V1 receptors. Noradrenaline acts as an agonist at α-adrenergic receptors with mild β-agonistic activity. The two major drugs used in the management of HRS act at different receptors and have completely varied mechanisms of action. Thus, a combination therapy would improve the rate of response considerably. There have been multiple studies, measuring the efficacy, safety and dosing of both drugs, but none combining both Terlipressin and Noradrenaline. Hence our study would be a pioneer in formulating a new and possibly more efficacious treatment protocol for patients of Type I HRS, in whom the treatment options are otherwise very limited. If successful, this would open new horizons of therapy for Terlipressin refractory HRS, which, otherwise is an ominous condition.
