Abstract

Malnutrition due to liver disease is common, however, its diagnosis is difficult. The parameters used for nutritional assessment in clinical practice have limited use in this patient population. From this perspective, this study proposes to develop predictive equations for body composition for bioelectrical impedance (BIA) in cirrhotic patients. Besides being a fast and risk free method, the BIA offers the additional advantage of low cost compared to other methods that evaluate body composition (BC). It will be selected patients with liver cirrhosis (n = 50) from the Liver Transplant Clinic of the Medicine School Hospital from the University of São Paulo, and healthy volunteers (n = 50) for the control group. After signing an informed consent, the patient sample will be divided into three groups according to the criteria of Child-Pugh (A, B or C), and their BC will be estimated by bioelectrical impedance analysis and by a reference method (multicomponent model). The data obtained by both methods will be statistically treated to obtain specific BIA prediction equations for the evaluation of cirrhotic patients. This pioneering study is of great clinical importance because malnutrition is a relevant factor in the prognosis of liver disease and there is not efficient method in clinical practice to properly assess the body composition in this patient category. Such knowledge, in turn, can be used as a new tool for nutritional assistance in treating this disease. (AU)
