Clinical Trial Summary

The study compares the effectiveness and safety of TIPS implantation in patients with HRS-AKI (stage 2 and 3) and liver cirrhosis with standard therapy (drug therapy with terlipressin + albumin).

Description:

Cirrhosis is a major cause of global health burden worldwide. Acute kidney injury (AKI) occurs in 20% of hospitalized patients with cirrhosis. Acute kidney injury is a relatively new definition of renal failure which takes into account the dynamic changes in serum creatinine. Among the causes of AKI, hepatorenal syndrome-AKI has the worst prognosis. HRS-AKI is an acute condition which occurs in patients with ascites, mainly refractory ascites. HRS-AKI includes the traditional hepatorenal syndrome type 1, which was defined by a serum creatinine cutoff and which has an ominous prognosis when left untreated, nevertheless HRS-AKI also includes milder forms of renal failure.

The standard treatment of HRS-AKI is with the infusion of albumin and terlipressin. Although this treatment improves renal function, patients remain at risk for new episodes of HRS-AKI and liver transplantation should be considered. Nevertheless, this optimal solution is only a reality for a privileged few given the shortage of organs and the common presence of contraindications.

Development of HRS-AKI is caused by increased pressure in the portal vein (the vein which brings the blood from the intestines to the liver), among other factors. Increased pressure in the portal vein, also called portal hypertension, is one of the main pathophysiological mechanisms that lead to the different complications of cirrhosis. Transjugular intrahepatic portosystemic shunt (TIPS) is an interventional radiological procedure which reduces the pressure in the portal vein by creating a short-cut between the portal vein and the hepatic vein, the vein which brings the blood from the liver towards the heart. TIPS placement has become the mainstay of treatment of some complications of cirrhosis, namely variceal bleeding and refractory ascites. Although rationally plausible, the use of TIPS in HRS-AKI has not been evaluated in the context of randomized controlled trials. Indirect data suggest that it could be helpful, since patients who become TIPS have an improvement in renal hemodynamics and renal function as well as less episodes of HRS-AKI in the follow-up. On the other hand, traditional HRS type 1 can be associated to liver failure and cardiac alterations which contraindicate TIPS placement. HRS-AKI includes not only traditional HRS type 1, but also milder forms of the disease, so that it is reasonable to consider that TIPS placement may have a role in this condition.

This study is a multicenter (9 centers), prospective, randomized controlled trial which evaluates use of TIPS in patients with HRS-AKI (stage 2 and 3) versus standard of care (albumin and terlipressin). Patients with cirrhosis and HRS-AKI who fulfill the inclusion criteria and do not have any exclusion criteria will be randomized to standard of care or standard of care and TIPS. Patients will be followed for a minimum of 12 months until the end of the trial. The main end-point is to compare the survival at the end of follow-up among the two groups.
