Using intravenous branched-chain amino acids to treat hepatic encephalopathy in liver failure patients

Intravenous Branched-chain Amino Acids for Overt Hepatic Encephalopathy in Patients With Acute on Chronic Liver Failure - A Multi-centric Double-blind Randomized Controlled Trial

PHASE1 · Post Graduate Institute of Medical Education and Research, Chandigarh · NCT05700695

This study tests whether giving intravenous branched-chain amino acids along with lactulose can help people with liver failure and severe confusion feel better and improve their health compared to just using lactulose alone.

What this trial studies

This multi-centric clinical trial investigates the effects of intravenous branched-chain amino acids (BCAA) on patients suffering from overt hepatic encephalopathy (HE) due to acute-on-chronic liver failure (ACLF). The study compares the efficacy of BCAA combined with lactulose against lactulose alone, focusing on ammonia levels, systemic inflammation, and cerebral edema. Additionally, it aims to assess overall survival rates and improvements in HE severity. The trial is designed to fill a gap in existing research regarding the adjuvant effects of intravenous BCAA in this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 with ACLF and hepatic encephalopathy of grade 2 or higher.

Not a fit: Patients with severe preexisting conditions, structural brain lesions, or those unable to consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the management of hepatic encephalopathy in patients with acute-on-chronic liver failure.

How similar studies have performed: While the use of BCAA in liver disease has been explored, this specific approach of intravenous BCAA for HE in ACLF is novel and has not been previously tested.
