Hepatocellular carcinoma (HCC) is a leading cause of liver-related death worldwide. Hepatitis C virus (HCV) infection is a major cause of advanced hepatic fibrosis and cirrhosis, with significantly increased risk for development of HCC. The morbidity and mortality of HCV-related HCC remains high, as rates of HCV cirrhosis continue to increase. The long-term goal of antiviral therapy for chronic HCV is to reduce complications from cirrhosis, including HCC. The advent of new direct-acting antivirals with high rates of virological clearance has revolutionized cure of HCV infection. While the development of HCC in HCV patients who achieve disease sustained virologic response is reduced, these patients remain at risk for HCC, particularly those patients with advanced fibrosis and cirrhosis. This review outlines the epidemiology of HCC in chronic HCV, various mechanisms, risk factors and pathophysiology that contribute to this disease process, screening recommendations, and the available data on the impact of new direct-acting antiviral treatment on the development on HCC.

Text messaging on healthy life style is associated with reduction in weight in NAFLD patients. Larger studies are suggested to examine benefits on liver histology, and assess long-term impact of this approach in patients with NAFLD.

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease worldwide and affects approximately one third of adults in the United States. The disease is becoming a global epidemic as a result of the rising rates of obesity and metabolic disease. Emerging data suggest weight loss of ≥10% overall body weight is beneficial in resolving steatosis and reversing fibrosis. Prospective trials comparing various diets are limited by lack of sufficient power as well as pre- and post-treatment histopathology, and therefore no specific diet is recommended at this time. In this narrative review we examine the pathophysiology behind specific macronutrient components that can either promote or reverse NAFLD to help inform more specific dietary recommendations. Overall, the data supports reducing saturated fat, refined carbohydrates, and red and processed meats in the diet, and increasing the consumption of plant-based foods. Diets that incorporate these recommendations include plant-based diets such as the Dietary Approaches to Stop Hypertension, Mediterranean, vegetarian, and vegan diets.

Identifying patients at high risk for acute kidney injury (AKI) during hospitalization among patients admitted with severe alcoholic hepatitis (AH) is an unmet clinical need. We performed a multicentric prospective cohort study using data from 4 different cohorts on well-characterized patients hospitalized with severe AH. Data collected on 773 AH patients from 4 cohorts across the globe were randomly split into test (n = 390) and validation (n = 383) cohorts. We found that 32% of the patients developed inpatient AKI in the test cohort. Approximately 60% of patients met criteria for systemic inflammatory response syndrome (SIRS) at admission. Hepatic encephalopathy, SIRS, and Model for End-Stage Liver Disease score at admission predicted inpatient AKI with odds ratios of 3.86, 2.24, and 1.14, respectively. The AKI risk score developed using these predictors stratified risk of inpatient AKI to low (score <3), moderate (3-4), and high (>4). These findings were replicated in the validation cohort. In the whole study cohort, patients with AKI had a lower 90-day survival (53% versus 77%; P < 0.001). Those with AKI risk score of >4 had significantly lower 90-day survival as compared with those with risk scores between 3 and 4 and <3 (47% versus 68% versus 88%; P < 0.001). In conclusion, AKI occurs frequently in AH patients and negatively impacts short-term mortality. The AKI risk score is useful in identifying patients at high risk for inpatient AKI and may be useful for developing new therapeutic strategies to prevent AKI in patients with AH.
