Abstract

BACKGROUND: Malnutrition frequently occurs in patients with liver cirrhosis independently for its etiology and can modify prognosis of the disease. Since malnutrition was observed at all clinical stages, but more frequently seen at advanced stages, early and detailed nutritional assessment in all patients with liver cirrhosis is important. The aims of this study are to define the nutritional status and the difference of nutritional index according to etiology and Child classification in patients with liver cirrhosis in Korea.
METHODS
A total 138 cirrhotic patients (41 alcoholic cirrhosis, 97 virus-related cirrhosis) were studied. The diagnosis of cirrhosis was based on clinical, laboratory and ultrasonographic criteria and liver biopsy. The patients were divided into three groups according to the severity of their liver disease as assessed by the Child-Pugh classification. Nutritional parameter of protein (serum albumin, serum transferrin, total lymphocyte count) were measured.
RESULTS
The patients with protein malnutrition are as follows: albumin 55, transferrin 68, total lymphocyte count 8. The frequency of moderate to severe protein malnutrition was high in alcoholic cirrhosis.: albumin (<2.9 g/dL) (26.8% vs 17.5%), transferrin (<180 mg/dL) (48.5% vs 24.8%), total lymphocyte count (<1200 number/L) (2.4% vs 2.0%). The mean value of nutritional index correlated with the degree of liver function impairment. (Child C showed the lowest value).
CONCLUSION
In spite of limitation of nutritional index in this study, our study showed that severe protein-energy malnutrition was rare in Korea, and protein-energy malnutrition was not only more common in alcoholic cirrhosis but related to the severity of liver disease. Therefore, our data suggests that clinician should understand the importance of not imposing unnecessary restrictions and supplementation on protein intake for fear of imbalance of nutrition.
