[Usefulness of branched-chain amino acid (BCAA)-enriched nutrient mixture for nutritional treatment undergoing endoscopic treatment for esophageal varices].

ABSTRACT

We investigated the alteration of nutritional status in 144 patients who were treated for the first time with endoscopic sclerotherapy or endoscopic variceal ligation during their therapies. The serum levels of albumin, cholinesterase and total cholesterol were compared before and after treatment. The serum level of cholinesterase declined significantly. To investigate the impact of aging on the changes of nutritional status we divided all patients into two groups (1) under 65 years, and (2) over 65 years. The decline of serum albumin of elderly patients (n=65) was significantly greater than that of younger patients (n=79). A branched-chain amino acid (BCAA)-enriched nutrient mixture for nutritional treatment significantly suppressed the decline of serum albumin in elderly patients. Nutritional treatment with a BCAA-enriched nutrient mixture should be considered during endoscopic therapy for esophageal varices, especially in elderly patients.
