  • Title: Preoperative nutrition assessment in liver transplantation.
    Author: Akerman PA, Jenkins RL, Bistrian BR.
    Journal: Nutrition; 1993; 9(4):350-6. PubMed ID: 8400592.
    Abstract:
    Nutrition assessment and therapy in end-stage liver disease has become increasingly important with the advent of orthotopic liver transplantation. Reduced lean body mass, increased risk of sepsis, and altered metabolism of carbohydrates, protein, and fat are characteristic of patients with liver dysfunction. This study assesses the prevalence of protein-calorie malnutrition and the relative utility of various parameters used to define protein-calorie malnutrition in 104 patients before liver transplantation. Five subgroups were identified for analysis: primary biliary cirrhosis (PBC, n = 21), sclerosing cholangitis (SC, n = 12), chronic active hepatitis (CAH,n = 34), acute hepatitis (AH,n = 11), and other liver diseases (OD,n = 26). Clinical characteristics, anthropometric measurements, secretory protein levels, 24-h urinary creatinine and urea nitrogen, and immunological studies were assessed. Significant differences between groups were noted in age, height, weight, and percentage ideal body weight (IBW), but no differences were noted with respect to triceps skin fold (TSF) and arm muscle circumference (AMC), where uniform depletion of fat and protein stores was found. Overall percentage IBW was significantly elevated (112 +/- 20, mean +/- SD, p < 0.001), whereas TSF and AMC percentage standards were 71 +/- 33 and 89 +/- 11% (respective p < 0.001). With the < 5th percentile of TSF and AMC as markers of malnutrition, 33 and 43% of patients were malnourished, respectively. Hepatic synthetic function was impaired in all groups, with overall albumin 25 +/- 0.6 g/L, transferrin 1.60 +/- 0.66 g/L, and prothrombin 16.8 +/- 6.2 s.(ABSTRACT TRUNCATED AT 250 WORDS)
