- Background amp; Aims Patients with non-alcoholic fatty liver disease (NAFLD) are at an increased risk for cardiovascular disease (CVD). It is unclear whether histological variables may help predict CVD risk. We evaluated histology and traditional CV risk factors as predictors of CVD outcomes in a large NAFLD cohort. Methods We included 603 biopsy-proven NAFLD patients free of baseline CVD and matched these (1:10, by age, sex and municipality) to 6269 population controls. All individuals were cross-linked to national registries to ascertain incident CVD events, defined as acute ischaemic heart disease or stroke. The presence of CV risk factors and liver histology were available in NAFLD patients only. Cox regression models were used to estimate hazard ratios (HR) for incident CVD. Results During a mean follow-up of 18.6 years, 168 (28%) of NAFLD patients and 1325 (21%) of controls experienced a CVD event (HR 1.54, 95%CI 1.30-1.83). Within the NAFLD cohort, age, male sex, type 2 diabetes, smoking and triglycerides were associated with risk of CVD. Taking these CV risk factors into account, no histological parameter, including presence of NASH and fibrosis stage, were associated with incident CVD. Conclusions Patients with NAFLD are at an increased risk for CVD compared to matched controls, but histological parameters do not seem to independently predict this risk.

- BACKGROUND AND AIMS: High levels of ferritin in patients with non-alcoholic fatty liver disease (NAFLD) are associated with significant fibrosis and higher NAFLD activity score (NAS). It is unclear if this association has an impact on mortality. We investigated if high levels of ferritin, with or without iron overload, were associated with an increased mortality in NAFLD.METHODS: We included 222 patients between 1979 and 2009 with biopsy-proven NAFLD and available serum ferritin concentrations. The cohort was divided into "high" (n = 89) and "normal" (n = 133) ferritin values, using a cut-point of 350 μg/L in males, and 150 μg/L in females, and stratified upon iron overload status. Data on mortality was obtained from a national, population based register. Poisson regression was used to estimate hazard ratios for mortality. The estimates were adjusted for age at biopsy, sex, smoking, BMI, diabetes, hypertension, cardiovascular disease and fibrosis stage at the time of biopsy.RESULTS: The median follow-up time was 15.6 years (range: 0.5-34.2). Patients with high ferritin had more advanced fibrosis and higher NAS than patients with normal ferritin (p < 0.05). Fifteen years after diagnosis, and after adjusting for confounders, the high-ferritin group showed an increasingly higher mortality that was statistically significant (Hazard ratio = 1.10 per year, 95% Confidence interval 1.01-1.21, p < 0.05). There was no difference in mortality between patients with different iron overload patterns.CONCLUSIONS: High levels of ferritin are associated with a long-term increased risk of death.

- Background & Aims Nonalcoholic fatty liver disease(NAFLD) is the second most common cause of liver transplantation in the US. Data on NAFLD as a liver transplantation indication from countries with lower prevalences of obesity are lacking. We studied the temporal trends of NAFLD as an indication for liver transplantation in the Nordic countries, and compared outcomes for patients with NAFLD to patients with other indications for liver transplantation. MethodResultsPopulation-based cohort study using data from the Nordic Liver Transplant Registry on adults listed for liver transplantation between 1994 and 2015. NAFLD as the underlying indication for liver transplantation was defined as a listing diagnosis of NAFLD/nonalcoholic steatohepatitis, or cryptogenic cirrhosis with a body mass index 25kg/m(2) and absence of other liver diseases. Waiting time for liver transplantation, mortality and withdrawal from the transplant waiting list were registered. Survival after liver transplantation was calculated using multivariable Cox regression, adjusted for age, sex, body mass index and model for end-stage liver disease. A total of 4609 patients listed for liver transplantation were included. NAFLD as the underlying indication for liver transplantation increased from 2.0% in 1994-1995 to 6.2% in 2011-2015 (P=.01) and was the second most rapidly increasing indication. NAFLD patients had higher age, model for end-stage liver disease and body mass index when listed for liver transplantation, but overall survival after liver transplantation was comparable to non--NAFLD patients (aHR 1.03, 95% CI 0.70-1.53 P=.87). ConclusionNAFLD is an increasing indication for liver transplantation in the Nordic countries. Despite more advanced liver disease, NAFLD patients have a comparable survival to other patients listed for liver transplantation.

- Background & Aims: The occurrence of drug-induced liver injury (DILI) is a major issue in all phases of drug development. To identify novel biomarker candidates associated with DILI, we utilised an affinity proteomics strategy, where antibody suspension bead arrays were applied to profile plasma and serum samples from human DILI cases and controls. Methods: An initial screening was performed using 4594 randomly selected antibodies, representing 3450 human proteins. Resulting candidate proteins together with proposed DILI biomarker candidates generated a DILI array of 251 proteins for subsequent target analysis and verifications. In total, 1196 samples from 241 individuals across four independent cohorts were profiled: healthy volunteers receiving acetaminophen, patients with human immunodeficiency virus and/or tuberculosis receiving treatment, DILI cases originating from a wide spectrum of drugs, and healthy volunteers receiving heparins. Results: We observed elevated levels of cadherin 5, type 2 (CDH5) and fatty acid-binding protein 1 (FABP1) in DILI cases. In the two longitudinal cohorts, CDH5 was elevated already at baseline. FABP1 was elevated after treatment initiation and seemed to respond more rapidly than alanine aminotransferase (ALT). The elevations were verified in the DILI cases treated with various drugs. In the heparin cohort, CDH5 was stable over time whereas FABP1 was elevated. Conclusions: These results suggest that CDH5 may have value as a susceptibility marker for DILI. FABP1 was identified as a biomarker candidate with superior characteristics regarding tissue distribution and kinetics compared to ALT but likely with limited predictive value for the development of severe DILI. Further studies are needed to determine the clinical utility of the proposed markers.
