Background: Malnutrition is a salient feature in patients with hepatic dysfunction; it is also an independent risk factor for morbidity and mortality in these patients. Factors that contribute to malnutrition in patients with hepatic failure include altered metabolic rate, fat malabsorption early satiety and impaired gastric emptying, frequent hospitalizations, over dietary restriction and glucose intolerance. Objective: The aim of work in this study is to assess the nutritional status among a group of Egyptian patients with Child’s C liver cirrhosis and also to correlate malnutrition to various complications of liver cirrhosis.Methods: This study conducted on 45 cirrhotic patients child C with or without complications .The patients were divided into two groups: group I included 3O patients with moderate to severe degree of malnutrition and group II which included 15 patients with mild degree of malnutrition. Results: rate of various complications is higher in patients with severe malnutrition ,TSFT and MAC has the highest sensitivity 85.71 %,100% & specificity 90 %,60% respectively to rate of complications(p value <0.0001 &area under the ROC curve= 0.879). Conclusion: it concluded that PCM is highly prevalent among patients with liver cirrhosis and it is directly related to the severity of the disease and to the rate of complications. Many tools are used to assess the nutritional status of patients with liver cirrhosis none of them is the gold standard for the nutritional assessment.
