BACKGROUND & AIMS The role of oral supplementation with branched-chain amino acids (BCAA) in advanced cirrhosis is far from settled. A nutritional approach might prevent progressive liver failure and improve nutritional parameters and quality of life. METHODS A multicenter, randomized study comparing 1-year nutritional supplementation with BCAA against lactoalbumin or maltodextrins was performed in 174 patients with advanced cirrhosis. Primary outcomes were the prevention of a combined end point (death and deterioration to exclusion criteria), the need for hospital admission, and the duration of hospital stay. Secondary outcomes were nutritional parameters, laboratory data and Child-Pugh score, anorexia, health-related quality of life, and need for therapy. RESULTS Treatment with BCAA significantly reduced the combined event rates compared with lactoalbumin (odds ratio, 0.43; 95% confidence interval, 0.19-0.96; P = 0.039) and nonsignificantly compared with maltodextrins (odds ratio, 0.51; 95% confidence interval, 0.23-1.17; P = 0.108). The average hospital admission rate was lower in the BCAA arm compared with control treatments (P = 0.006 and P = 0.003, respectively). In patients who remained in the study, nutritional parameters and liver function tests were, on average, stable or improved during treatment with BCAA and the Child-Pugh score decreased (P = 0.013). Also, anorexia and health-related quality of life (SF-36 questionnaire) improved. Long-term compliance with BCAA was poor. CONCLUSIONS In advanced cirrhosis, long-term nutritional supplementation with oral BCAA is useful to prevent progressive hepatic failure and to improve surrogate markers and perceived health status. New formulas are needed to increase compliance.

Abstract In a double blind randomized study, branched-chain amino acids and placebo (casein) were compared as a treatment for chronic hepatic encephalopathy in cirrhosis. After a 15-day run-in period with controlled diet (45–65 g protein), the patients were administered, in addition to their diet, branched-chain amino acids (0.24 g/kg, 30 patients) or an equinitrogenous amount of casein (34 patients). One patient on branched-chain amino acids and two on casein were lost to the study. After 3 months, the index of portal-systemic encephalopathy significantly improved in patients on active treatment (from 40 [S.D. 14]% to 21 [17]), but was not in subjects receiving casein (from 37 [13]% to 36 [12]). Two or more parameters of the index improved in 24 patients treated with amino acids (80%; confidence limits, 61–92%), and only in 12 receiving casein (35%; confidence limits, 20–54%; p

In 40 patients with cirrhosis on a dietary protein regimen of 1 g/kg b.w., we determined the effect on chronic hepatic encephalopathy of long-term administration of Enterococcus faecium (SF68) versus lactulose. The patients received one of the two treatments for three periods of 4 weeks, each separated by drug-free 2-week intervals. The efficacy of treatment was assessed by arterial blood ammonia concentration, mental status, number connection (Reitans part A) test and flash-evoked visual potentials. At the end of the third period the reduction in both blood ammonia concentrations and Reitans test times was more enhanced in patients on SF68 than in patients on lactulose. Furthermore, while patients on lactulose tended to return to basal values during drug-free intervals, responders in the SF68 group maintained improvement throughout the study. In conclusion, SF68 is at least as useful as lactulose for the chronic treatment of chronic hepatic encephalopathy; it has no adverse effects, and treatment can be interrupted for 2 weeks without losing the beneficial effects.

BACKGROUND It has been shown that health-related quality of life is reduced in patients with cirrhosis and with chronic hepatitis in relation to antiviral therapy. No data are available on patients with hepatocellular carcinoma. AIM To assess health-related quality of life in cirrhotic patients with hepatocellular carcinoma. PATIENTS AND METHODS Health-related quality of life was assessed in 101 hepatocellular carcinoma patients by means of Short Form-36 and Nottingham Health Profile questionnaires. Final scores of domains for individual patients were compared to age-adjusted normative Italian values, using Z-score and with values obtained in 202 matched patients with cirrhosis, without hepatocellular carcinoma. RESULTS All Short Form-36 domains and 4 out of 6 Nottingham Health Profile domains were altered. When hepatocellular carcinoma patients were compared with matched cirrhotics, differences were present for Bodily Pain, Role Limitation-Physical, and the Physical Component Summary of Short Form-36, as well as Pain of Nottingham Health Profile. Perceived health status had changed significantly in the year prior to assessment. Health-related quality of life was not primarily related to tumour mass or hepatocellular failure, whereas sleep disorders were selected by logistic regression as strongly associated with poor health-related quality of life. CONCLUSIONS The present data stress the relevance of pain in poor perceived health status of hepatocellular carcinoma patients, and the importance of minor symptoms, such as sleep disorders.
