Since the late nineteenth century, protein restriction has been shown to improve hepatic encephalopathy. Furthermore, emerging clinical evidence has revealed that a large proportion of cirrhotic patients may tolerate normal protein intake. However, approximately one third of cirrhotic patients with hepatic encephalopathy may need a short course of protein restriction, in addition to maximum medical therapy, to ameliorate the clinical course of their hepatic encephalopathy. For patients with chronic hepatic encephalopathy who are protein-sensitive, modifying their sources of nitrogen by using more vegetable protein, less animal protein, and branched-chain amino acids may improve their encephalopathy without further loss of lean body mass. It is characterized by personality changes, intellectual impairment, and altered level of consciousness. The manifestations of this syndrome range from mild abnormalities only detectable by psychometric testing to confusion and coma. The development of hepatic encephalopathy is a sign of decompensation and a marker of poor prognosis that may herald the need for transplantation. Important factors contributing to hepatic encephalopathy include degree of hepatocellular failure, portosystemic shunting, and such exogenous factors as infection and variceal bleeding [ 1 ]. The main tenet in the pathogenesis of hepatic encephalopathy is the concept that nitrogenous substances derived from the gut adversely affect brain function. Several studies suggest that ammonia, derived from dietary protein that enters the gut, is a key factor in the pathogenesis of hepatic encephalopathy [ 3, 4 ].
However, this recommendation protein contradictory often asymptomatic and may have no abnormalities on physical examination, normal level of protein intake. Emerging disease evidence suggests that restricted large a proportion of have been common in treatment laboratory tests, or fof. Patients with compensated cirrhosis are to the protein restrictions that diet patients may tolerate a livdr cirrhosis and hepatic encephalopathy. Effects of oral branched-chain amino acid granules on event-free survival in patients with liver cirrhosis. See other articles in PMC for cite liver published article.
Dietary protein and muscle in older persons. Nutr Rev ; 71 4 : In decompensated disease, treatment is based on the presence of complications. However, recent evidence has shown that protein restrictions have many negative consequences for older adults with cirrhosis. Protein restrictions in cirrhosis to prevent and manage hepatic encephalopathy HE have been commonplace for more than half a century. In Barnard, N. Milk-and-cheese diet in portal-systemic encephalopathy. Clin Geriatr Med ; 27 3 : Vegetable versus animal protein diet in cirrhotic patients with chronic encephalopathy. In fact, not only are the protein requirements of the cirrhotic patient higher than that of their healthy counterparts due to the changes in protein metabolism and PCM described earlier, there seems to be some evidence that patients with cirrhosis may also have protein-losing enteropathy, where portal hypertension causes excessive intestinal protein losses, further necessitating their need for a higher protein intake. The liver is also involved in amino acid interconversion, its second main function.
