Show moreBackground and aims: Malnutrition is highly prevalent in patients with end-stage liver disease (ESLD) and associated with impaired clinical outcome. Previous studies focused on one component of body composition and not in combination with nutritional intake, while both are components of the nutritional status. We aimed to evaluate the most important risk factors regarding body composition (muscle mass, muscle quality and fat mass) and nutritional intake (energy and protein intake) for waiting list mortality in patients with ESLD awaiting liver transplantation (LTx).Methods: Consecutive patients with ESLD listed for LTx between 2007 and 2014 were investigated. Muscle mass quantity (Skeletal Muscle Mass Index, SMI), and muscle quality (Muscle Attenuation, MA), and various body fat compartments were measured on computed tomography using SliceOmatic. Nutritional intake (e.g. energy and protein intake) was assessed. Multivariable stepwise forward Cox regression analysis was used for statistical analysis.Results: 261 Patients (mean age 54 years, 74.7% male) were included. Low SMI and MA were found to be statistically significant predictors of an increased risk for waiting list mortality in patients with ESLD, with a HR of 2.580 (95%CI 1.055-6.308) and HR of 9.124 (95%CI 2.871-28.970), respectively. No association between percentage adipose tissue, and protein and energy intake with waiting list mortality was found in this study.Conclusion: Both low muscle quantity and quality, and not nutritional intake, were independent risk factors for mortality in patients with ESLD.

Show moreInformation on prognosis is essential for any physician for providing information to the patient and forms the basis for the decision-making process for therapy. Due to the heterogeneity of the disease, exploration of prognostic biomarkers in cirrhosis is a challenging, but important aspect of research in the field of chronic liver disease. Besides identifying patients who are at the highest risk of mortality, identification of reliable prognostic biomarkers may also help to improve treatment strategies. The aim of this thesis is to explore novel prognostic biomarkers throughout different stages of chronic liver disease and in acute-on-chronic liver failure (ACLF). Show less
