Predictors of mortality in patients on the waiting list for liver transplantation. Nutr. Hosp. [online]. 2013, vol.28, n.3, pp.914-919. ISSN 1699-5198.  https://dx.doi.org/10.3305/nh.2013.28.3.6333.

Background and aim: The demand for liver transplantation (LTx) increases every year, which is in contrast to the stagnation in the number of donors. This phenomenon has given rise to longer waiting times, which results in higher pre-transplantation mortality. Thus, our aim for this study was to identify risk factors, including nutritional variables, for mortality for patients who are on the waiting list for LTx. Methods: Patients on the waiting list were assessed to identify risk factors for mortality. Data related to demographic, socioeconomic, and etiologic factors, liver disease severity, complications, medications, and biochemical tests related to disease, nutritional status, diet intake, and physical activity were collected. Results: There were 159 patients followed, and 47.8% (76) were transplanted. The mortality rate while on the waiting list was 25.7% patient-years, and 40 patients died (28.0%). Variables associated with mortality during this period (p < 0.05) were the following: severe malnutrition (OR 2.5/CI: 1.2-5.3), low serum sodium values (OR: 1.1/CI: 1.01-1.2), and cryptogenic cirrhosis (OR: 2.2/CI: 1.1-4.6). Conclusions: Special attention should be given to patients with low serum sodium, those who are diagnosed with cryptogenic cirrhosis and the severely malnourished. An early diagnosis of malnutrition and an appropriate nutritional intervention is mandatory in such patients.
