Renal Dysfunction in Cirrhotic Patients

Terlipressin in the management of liver disease

INTRODUCTION

Terlipressin is a synthetic vasopressin analog which has been recently approved in the United States by the Food and Drug Administration for the treatment of hepatorenal syndrome. Terlipressin stimulates vasopressin receptors located on the smooth muscle vasculature of the splanchnic circulation and renal tubules which results in splanchnic vasoconstriction with improved renal perfusion and antidiuretic activity, respectively.

AREAS COVERED

In this review, we discuss available data regarding the FDA approved use of terlipressin, safety, and tolerability, as well as highlight alternative uses in chronic liver disease currently still under investigation.

EXPERT OPINION

Terlipressin is more efficacious compared to other vasoactive agents including midodrine octreotide and norepinephrine in reversal of hepatorenal syndrome and improves short-term survival. Other potential applications of terlipressin's vasoconstrictor actions reported in the literature include management of variceal hemorrhage and other complications of portal hypertension.

An Integrated Review of the Hepatorenal Syndrome

Among the complications of cirrhosis, hepatorenal syndrome (HRS) is characterized by having the worst survival rate. HRS is a disorder that involves the deterioration of kidney function caused primarily by a systemic circulatory dysfunction, but in recent years, systemic inflammation and cirrhotic cardiomyopathy have been discovered to also play an important role. The diagnosis of HRS requires to meet the new International Club of Ascites-Acute Kidney Injury (ICA-AKI) and Hepatorenal Syndrome-Acute Kidney Injury (HRS-AKI) criteria after ruling out other causes of kidney injury. At the time of diagnosis, it is important to start the medical treatment as soon as possible where three types of vasoconstrictors have been recognized: vasopressin analogs (ornipressin and terlipressin), alpha-adrenergic agonists (norepinephrine and midodrine) and somatostatin analogues (octreotide); all should be combined with albumin infusion. Among them, terlipressin and albumin are the first lines of treatment in most cases, although terlipressin should be monitor closely due to its adverse events. The best treatment of choice is a liver transplant, because it is the only definitive treatment for this disease.
