Nutritional status using subjective global assessment independently predicts outcome of patients waiting for living donor liver transplant.

BACKGROUND: Malnutrition is an important risk factor for adverse outcomes in patients awaiting liver transplant. Living donor liver transplant, being an elective procedure, allows nutritional rehabilitation and optimization of these patients before transplant. AIM: This paper aimed to evaluate the outcome of end-stage liver disease (ESLD) patients with various degrees of malnutrition waiting for living donor liver transplant.
METHODS: Nutritional status was assessed using subjective global assessment (SGA) in patients who were evaluated for a liver transplant at our center from January 2015 to September 2015. All the data were collected prospectively. Predictive factors for mortality were analyzed using logistic regression and survival was obtained using Kaplan-Meier curves.
RESULTS: One hundred and seventeen patients were grouped based on their nutrition status into normal, mild-moderate, and severe malnutrition. The groups were comparable in terms of age, sex, etiology of liver disease except alcoholic liver disease. Graft recipient weight ratio was comparable among groups. There was no significant difference in hospital stay. However, severe malnourished patients had higher incidence of sepsis (p=0.005) and death due to sepsis (p=0.01). Nutritional status was the only independent predictor of mortality on multivariate analysis.
CONCLUSION: Nutritional status measured with SGA independently predicts short-term outcome of ESLD patients waiting and after living donor liver transplant.
