Abstract
OBJECTIVES Alcohol-associated liver disease is increasing, especially hospitalizations with acute on chronic liver failure and need for liver transplant. We examined trends in prevalence, inhospital mortality, and resource utilization associated with AALD and ACLF in the young. METHODS The National Inpatient Sample (2006-2014) was queried for hospitalizations with a discharge diagnosis of cirrhosis using the International Classification of Diseases, Ninth Edition, codes. ACLF hospitalization was defined as ≥2 organ failures and stratified by age: young (≤35 years) and older (>35 years). RESULTS Of 447,090 AALD admissions (16,126 in young) between 2006 and 2014, ACLF occurred in 29,599 (6.6%), of which 1,143 (7.1%) were in young. Compared with older, admissions in young had more women (35% vs 29%), were obese (11% vs 7.6%), were Hispanics (29% vs 18%), have alcoholic hepatitis (AH) (41% vs 17%), and have ACLF grades 2 or 3 (34% vs 25%), P < 0.001 for all. Between 2006 and 2014, ACLF in AALD among young increased from 2.8% to 5.2%, with an AH proportion from 24% to 42%, P < 0.0001 for both. Young had more complications requiring ventilation (79% vs 76%) and dialysis (32% vs 28%), P < 0.001 for both. Compared with older, ACLF admission in young had longer hospitalization (12 vs 10 days) with higher hospital charges ($127,915 vs $97,511), P < 0.0001 for both, with 20% reduced inhospital mortality (54%-45%), P < 0.001. DISCUSSION AALD-related hospitalizations are increasing in young in the United States, mainly because of the increasing frequency of AH. Furthermore, this disease burden in young is increasing with a higher frequency of admissions with more severe ACLF and consumption of hospital resources. Studies are needed to develop preventive strategies to reduce burden related to AALD and ACLF in young.

Abstract
Nonalcoholic fatty liver disease (NAFLD) affects at least 25% of the general adult population worldwide. Because only a fraction of the patients would develop liver-related complications, it is preferable to perform non-invasive tests as the initial assessment. This review summarizes the known and potential confounding factors that affect the performance of non-invasive tests of hepatic steatosis and fibrosis in patients with NAFLD. Clinicians may apply the knowledge and exercise caution in selecting investigations and interpreting test results when confounding factors are present.

[PMID: 31272131 DOI: 10.1111/jgh.14778] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2019] [Revised: 05/31/2019] [Accepted: 06/29/2019] [Indexed: 01/13/2023]
Abstract
BACKGROUND Studies on association between fatty liver disease and overall mortality have yielded conflicting results. We evaluated the impact of fatty liver disease and advanced fibrosis on overall morality with a focus on body size and abdominal fat distribution measured by computed tomography. METHODS We performed a prospective cohort study including 34 080 subjects (mean age, 51.4 years; 58.6% men) who underwent abdominal ultrasonography and fat computed tomography, from 2007 to 2015. Fatty liver was diagnosed by ultrasonography, and advanced fibrosis was defined as high probability of advanced fibrosis based on three noninvasive methods, aspartate aminotransferase-to-platelet ratio index, non-alcoholic fatty liver disease fibrosis score, and fibrosis-4 score. Body size was categorized by body mass index into obese (≥ 25 kg/m2 ) or nonobese (< 25 kg/m2 ). Multivariate proportional Cox hazard regression analyses were performed. RESULTS The prevalence of fatty liver disease was 37.5%, while the prevalence of advanced fibrosis in fatty liver disease was 1.8%. During a median follow-up of 87 months (interquartile range, 62-110), 296 deaths occurred. Fatty liver disease was not associated with higher overall mortality (multivariate-adjusted hazard ratio [HR] 1.02, 95% confidence interval [CI] 0.77-1.34), while increased subcutaneous adiposity was associated with decreased mortality (HR 0.72, 95% CI 0.60-0.88). Advanced fibrosis resulted in a 3.5-fold increase in overall mortality (adjusted HR 3.52, 95% CI 1.86-6.65), which was more pronounced in the nonobese. CONCLUSIONS While fatty liver disease did not impact overall mortality, subcutaneous adiposity was associated with reduced overall mortality. Advanced fibrosis was an independent predictor of increase in overall mortality.

Abstract
The growing global epidemic of obesity and type 2 diabetes mellitus (T2DM) has led to the increasing prevalence of nonalcoholic fatty liver disease. In addition, the presence of obesity and T2DM has been shown to increase the likelihood of adverse outcomes in patients with chronic liver disease. In a study by Harris et al., a combination of obesity and T2DM was associated with an increased risk for higher liver stiffness, as measured by transient elastography. It is possible that public health and clinical intervention targeting these components of metabolic syndrome can lead to improved outcomes of subjects with nonalcoholic fatty liver disease and other chronic liver diseases.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is correlated with low-grade inflammation and dietary habits. Until today, there have been limited epidemiologic data assessing the role of diet's inflammatory potential on NAFLD. The aim was to evaluate the relationship between an anti-inflammatory diet, as reflected by the Dietary Anti-Inflammation Index (D-AII), and NAFLD among cardiovascular disease (CVD)-free adults. METHODS ATTICA is a prospective, population-based study that recruited 3042 adults without pre-existing CVD from the Greek population (Whites; age ⩾18 years; 1514 men and 1528 women). D-AII was calculated using a standard procedure. The baseline study captured various sociodemographic, lifestyle and clinical characteristics as well as hepatic markers. These were used to calculate four NAFLD assessment indices: triglyceride-glucose (TyG) index, fatty liver index (FLI), hepatic steatosis index (HSI), and NAFLD Fatty Liver Score (NAFLD-FLS). Specific cutoffs were applied to capture NAFLD. RESULTS D-AII showed a significant inverse association with NAFLD, applying the four indices with NAFLD cutoffs [odds ratio (OR) with 95% confidence interval (CI); TyG (0.95, 0.93-0.98); HSI (0.89, 0.86-0.92); FLI (0.88, 0.85-0.91); NAFLD-FLS (0.89, 0.86-0.92)], after adjusting for various confounders. Participants in the highest D-AII tertile had lower odds of having NAFLD, compared with those in the lowest D-AII tertile [(OR, 95% CI); TyG (0.33, 0.24-0.47); HSI (0.13, 0.08-0.23); FLI (0.05, 0.02-0.11); NAFLD-FLS (0.13, 0.07-0.23)]. Anti-inflammatory nutrition was related to lower odds of NAFLD among daily alcohol drinkers and individuals with metabolic syndrome. CONCLUSIONS Anti-inflammatory diet is an important predictor of NAFLD among adults without pre-existing CVD. Adherence to a high anti-inflammatory diet seems to contribute to NAFLD prevention.

Abstract
BACKGROUND Understanding whether the associations between alcohol use and alcohol use disorder (AUD) differ by weight status may be useful in screening for AUD in populations where obesity is common. We aimed to determine whether the associations between alcohol use and AUD differ by weight status. METHODS A total of 24,869 adult participants of the National Epidemiologic Survey on Alcohol and Related Conditions-III with a body mass index ≥18.5 kg/m2 who reported past-year alcohol use were included. The AUD and Associated Disabilities Interview Schedule-5 were administered to identify past-year AUD. Logistic regression was used to test the associations between weight status and levels and patterns of alcohol use with AUD; interactions between weight status and alcohol use variables in relation to AUD were examined. Analyses were stratified by gender. RESULTS For males and females, the odds of AUD were higher with greater frequency of any alcohol use and heavy drinking, higher average quantity of drinks per drinking day, and past-year high-risk drinking. Among males, at the same average quantity of drinks per drinking day, frequency of heavy drinking, or presence of high-risk drinking, those with class 3 obesity had higher odds of AUD versus lower classes or no obesity (p for all interactions <0.01). Among females, at the same frequency of any alcohol use, those with healthy weight had the highest odds of AUD, while females with class 3 obesity had the lowest odds of AUD (p for interaction <0.001); interactions between weight status and other alcohol use variables were not significant (p ≥ 0.05). CONCLUSIONS The associations between some measures of alcohol use and AUD differed by weight status, with inconsistent results between males and females. Alcohol use thresholds typically used in AUD screening may be too high in males with class 3 obesity.
