Results: Levels of 20 amino acids and

Results: Levels of 20 amino acids and this website metabolites were significantly higher in study participants with obesity when compared to lean participants (p=0.03-0.001). Patients with NASH (versus simple steatosis and normal histology) had higher levels of alanine (chi square 6.32, p = 0.01), b-aminobutyric acid (chi square 4.99, p= 0.03), 2 of the 3 aromatic amino acids; tyrosine (chi square 4.99, p = 0.03), and tryptophan (chi square 7.55, p = 0.006). Histological

liver injury parameters correlated negatively with branched chain amino acids and aromatic amino acids, alanine and several other amino acids. Conclusion: This study illustrates that obesity, despite chronic overnutrition, is associated with an amino acid profile that is profoundly proteolytic / catabolic in nature. Amino acid abnormalities

correlated with histological features of NASH. This proteolytic profile seen in this study has been shown to cause distinct metabolic effcts; i. e. the increase in serum amino acids and increased BCAA oxidation has been associated with increased mTOR activity, contributing to insulin resistance, mitochondrial dysfunction, and increased cancer and cardiovascular risk. Further research is necessary to determine the effects of increased amino acids, mTOR and liver injury in the context of NASH. Disclosures: The following people have Lumacaftor concentration nothing to disclose: Maureen M. Guichelaar, Anuradha Krishnan, Edith M. Koehler, X. Mai Persson, Sreekumaran K. Nair, Michael R. Charlton Background: Living donor liver transplantation (LDLT) has been increasing due to the critical shortage of cadaver livers and the increasing number of patients waiting for LT. Hepatic steatosis is an important factor associated with primary non-function of the recipient allograft as well as an increase in the risk of donor complications caused by a reduced functional hepatic mass. To date, there is no consensus

regarding the pre-donation workup strategy for selecting appropriate donor livers. The purpose 上海皓元 of this study is to assess the optimal tools for evaluating the donor liver fat content. Method: A total of 1, 766 living donors underwent abdominal ultrasonography (USG) and computed tomography (CT) as donor selection procedures, along with preoperative right liver biopsy and intraoperative paired right and left liver biopsies. The agreement of the steatosis grade (<5%; 5-15%; 15-30%; and >30%) between imaging and biopsy and between biopsies was assessed using the k statistic, and the clinico-metabolic factors related to sampling variability were identified using logistic regression analysis. Result: The sensitivities of USG and CT were 58.9% and 46.4%, respectively, for detecting >30% steatosis with positive predictive values of 6.9% and 16.9%.
