Comparative Study Observational Study
Role of ammonia, inflammation, and cerebral oxygenation in brain dysfunction of acute-on-chronic liver failure patients.
Hepatic encephalopathy (HE) is a common feature of acute-on-chronic liver failure (ACLF). Although ammonia, inflammation, and cerebral oxygenation are associated with HE in acute liver failure, their roles in ACLF are unknown. The aim of this prospective, longitudinal study was to determine the role of these pathophysiological variables in ACLF patients with and without HE. ⋯ The results suggest that ammonia, JVO2 , and WCC are important prognostic biomarkers and therapeutic targets. The relative roles of these pathophysiological factors in the pathogenesis of HE in ACLF or guiding therapy to improve survival requires future study. Liver Transplantation 22 732-742 2016 AASLD.

The effects of diabetic status and acute rejection (AR) on liver transplant outcomes are largely unknown. We studied 13,736 liver recipients from the United Network for Organ Sharing/Organ Procurement Transplant Network database who underwent transplantation between 2004 and 2007 with a functioning graft for greater than 1 year. The association of pretransplant diabetes mellitus (PDM), new-onset diabetes after transplant (NODAT), and AR rates on allograft failure, all-cause mortality, and cardiovascular mortality were determined. ⋯ The analyses in both HCV-positive and HCV-negative cohorts showed a similar trend as in the overall cohort. In conclusion, PDM and AR, but not NODAT, is associated with increased mortality and liver allograft failure. Liver Transplantation 22 796-804 2016 AASLD.
