Assessment of nutritional status of patients with hepatitis C virus-related liver cirrhosis.
OBJECTIVE
Nutrition support for patients with liver cirrhosis, such as late evening snacks and branched-chain amino acids, has been demonstrated to be effective. However, the assessment of the malnutrition of liver cirrhosis is still a problem. The aim of this study was to assess the nutritional status of patients with liver cirrhosis due to hepatitis C virus by six methods and to test the sensitivity and specificity of these methods.


METHODS
In total, 86 patients with liver cirrhosis due to hepatitis C virus were assessed for nutritional status by triceps skinfold thickness (TSF), arm muscle circumference (AMC), subjective global assessment (SGA), nutritional risk index (NRI), Maastricht index (MI), and instant nutritional assessment (INA).


RESULTS
Malnutrition was found in 11 (12.8%) patients by TSF, 15 (17.4%) by AMC, 22 (25.6%) by SGA, 52 (60.5%) by the NRI, 66 (76.7%) by the MI, and in 54 (62.8%) by INA. The MI detected malnutrition at a significantly higher rate compared with the other five methods. Sixty-two patients were diagnosed as malnourished by the combined index, which defines the patients as malnourished when any two of the NRI, MI, and INA also define them as malnourished. The misclassification rate compared with the combined indexes was significantly lower in the MI (4.7%) than in any of the TSF (59.3%), AMC (59.3%), SGA (46.5%), NRI (16.3%), and INA (14.0%).


CONCLUSIONS
The MI was the best single score to identify the patients who had malnutrition, including early stage, and may benefit from nutrition support.
