Oral Branched-chain Amino Acid Supplementation for Cirrhotic Patients With Sarcopenia

Summary

The goal of this clinical trial is to compare the nutritional parameters after 24-week supplementation of branched-chain amino acids in cirrhotic patients with low muscle mass.

The main questions it aims to answer are:

Is there the differences in the proportions of cirrhotic patients recovering from low muscle mass at 24 weeks among cirrhotic patients with low muscle mass who received BCAA supplementation and the placebo group? Is there the differences in the change of skeletal muscle index (SMI) measured by abdominal computed tomography (CT) at 24 weeks among cirrhotic patients with low muscle mass who received BCAA supplementation and the placebo group? Is there changes in other indices related to low muscle mass, including appendicular skeletal muscle mass (ASM), ASM/height\^2, handgrip strength, and 6-meter walk speed at 24 weeks among cirrhotic patients with low muscle mass who received BCAA supplementation and the placebo group? Is there changes in the liver frailty index (LFI), consisting of handgrip strength, chair stands, and balance, at 24 weeks among cirrhotic patients with low muscle mass who received BCAA supplementation and the placebo group? Is there changes in serum albumin levels, at 24 weeks among cirrhotic patients with low muscle mass who received BCAA supplementation and the placebo group? Is there changes in severity of liver disease, including the Model for End-Stage Liver Disease-Sodium Score (MELD-Na score), Child-Turcotte-Pugh score, and liver stiffness measured by transient elastography at 24 weeks among cirrhotic patients with low muscle mass who received BCAA supplementation and the placebo group?

Participants will be asked to do following tasks:

Participants will be asked for basic information such as age, place of residence, and contact phone number.

Participants will undergo measurements of body weight, height, body mass index (BMI), muscle mass, and body fat content using a body composition analyzer, a total of 2 times (at the beginning and end of the research), and an upper abdominal computed tomography (CT) scan without additional radiation exposure, only once (at the end of the research) throughout the study.

Participants will be tested for muscle function, including handgrip strength, a 6-meter walk test, chair stands, and balance, all performed twice (at the beginning and end of the research).

Laboratory testing will include a complete blood count, liver and kidney function, blood clotting function, mineral levels, cholesterol, and glucose. Blood will be drawn a total of 2 times (at the beginning and end of the research) during the study, with each blood draw approximately 15 milliliters (1 tablespoon).

Transient elastography will be performed twice (at the beginning and end of the research) during the study, with each Transient elastography taking approximately 10 minutes.

Participants will be randomly assigned to either the group receiving branched chain amino acid (BCAA) medication or the placebo group, and you will take the assigned medication twice daily for a total of 24 weeks.

Participants will receive dietary and exercise recommendations from the research team and nutritionists in a group format, taking approximately 1 hour.

Participants will have follow-up appointments to monitor your condition three times during the study, at weeks 4, 12, and 24. These appointments will include inquiries about side effects from medication and placebo use, exercise, and dietary intake, each lasting approximately 30 minutes.

Participants will be asked to take photos of your daily meals for 3 days before meeting with the physician at weeks 4 and 12, to provide data for assessing your calorie intake. Participants can send these meal images via the online application, prepared by our research team. If participants are unable to do so, participants will be asked to keep a food diary and report your food and portion sizes to the research team.

Conditions

• Sarcopenia
• Cirrhosis of the Liver

Interventions

DRUG

Branched-chain amino acid

In the BCAA group, participants will receive oral BCAA for 24 weeks, with a daily dosage of approximately 13.68 g/day. Each sachet of BCAA will contain 6.84 g of BCAA (valine 1.82 g, leucine 3.29 g, isoleucine 1.72 g), total protein 17.08 g, carbohydrates 25.48 g, fat 5.66 g, providing 221.2 kcal of energy. Each sachet weighs 52 g and should be mixed with 150 ml of water. Participants will consume 2 sachets daily, one after breakfast and one after dinner.

DRUG

Placebo

In the placebo group, BCAA will be replaced with maltodextrin. Each sachet of the placebo will contain a total of 5.93 g of protein, 35.87 g of carbohydrates, 6.00 g of fat, providing 221.2 kcal of energy. Like the BCAA sachets, each placebo sachet will weigh 52 g and should be mixed with 150 ml of water. Participants in the placebo group will consume 2 sachets daily, one after breakfast and one after dinner.
