RESUMO
OBJECTIVES: Sarcopenia is a common entity in cirrhosis with significant morbidity and mortality. However,the effects of sarcopenia on the risk of complications and survival after liver transplant remain controversial.We aimed to evaluate the effect of sarcopenia on survival and complications after liver transplant. MATERIALS AND METHODS: Our study cohort included 61 adult patients with hepatitis C-related cirrhosis who underwent living donor liver transplant. Pretransplant clinical and anthropometric assessments included body mass index, hand grip, mid-arm circumference, triceps skin fold thickness, and gait speed. Sarcopenia was determined by computed tomography using the skeletal muscle index at the third lumbar vertebra cut-off value of <38.5 cm2/m2 for women and <52.4 cm2/m2 for men; these patients were then followed up for 6 months after transplant to determine survival and complications. RESULTS: At time of liver transplant, sarcopenia was present in 27/61 patients (44.3%). At follow-up after transplant, sarcopenia was found in 14 patients (30.4%) among 46 survivors; all patients who survived were male patients. Among patients with sarcopenia posttransplant, 12 had sarcopenia before transplant and 2 developed sarcopenia after transplant. Liver dysfunction, lower triceps skin fold thickness, recent infections, and sarcopenia pretransplant were associatedwithposttransplant complications, especially infection(42.8%) and prolonged intensive careunit stay. Age and pretransplant sarcopenia were found to be independent predictors of posttransplant mortality. CONCLUSIONS: Sarcopenia is a common entity in patients with cirrhosis who are on liver transplant wait lists and may continue after liver transplant. De novo sarcopenia after liver transplant is also a common finding. Sarcopenia can affect patient outcomes, including prolonged intensive care unit stay and poor short-term survival.
