    (2021) Singal, Ashwani K.; Arsalan, Arshad; Dunn, Winston; Arab, Juan P.; Wong, Robert J.; Kuo, Yong-Fang; Kamath, Patrick S.; Shah, Vijay H.
    Background Alcohol use and alcohol-associated liver disease (ALD) burden are increasing in young individuals. Aim To assess host factors associated with this burden. Methods National Health and Nutrition Examination Survey (NHANES), National Inpatient Sample (NIS), and United Network for Organ Sharing (UNOS) databases (2006-2016) were used to identify individuals with harmful alcohol use, ALD-related admissions, and ALD-related LT listings respectively. Results Of 15 981 subjects in NHANES database, weighted prevalence of harmful alcohol use was 17.7%, 29.3% in <35 years (G1) versus 16.9% in 35-64 years (G2) versus 5.1% in >= 65 years (G3). Alcohol use was about 11 and 4.7 folds higher in G1 and G2 versus G3, respectively. Male gender and Hispanic race associated with harmful alcohol use. Of 593 600 ALD admissions (5%, 77%, and 18% in G1-G3 respectively), acute on chronic liver failure (ACLF) occurred in 7.2%, (7.2 in G2 vs 6.7% in G1 and G3, P < 0.001). After controlling for other variables, ACLF development among ALD hospitalizations was higher by 14% and 10% in G1 and G2 versus G3, respectively. Female gender and Hispanic race were associated with increased ACLF risk by 8% and 17% respectively. Of 20,245 ALD LT listings (3.4%, 84.4%, and 12.2% in G1-G3 respectively), ACLF occurred in 28% candidates. Risk of severe (grade 2 or 3) ACLF was higher by about 1.7 fold in G1, 1.5 fold in females and 20% in Hispanics. Conclusion Young age, female gender, and Hispanic race are independently associated with ALD-related burden and ACLF in the United States. If these findings are validated in prospective studies, strategies will be needed to reduce alcohol use in high risk individuals to reduce burden from ALD.

    Disparities in steatosis prevalence in the United States by Race or Ethnicity according to the 2023 criteria
    (2024) Díaz, Luis Antonio; Lazarus, Jeffrey V.; Fuentes López, Eduardo; Idalsoaga Ferrer, Francisco Javier; Ayares Campos, Gustavo Ignacio; Desaleng, Hailemichael; Danpanichkul, Pojsakorn; Cotter, Thomas G.; Dunn, Winston; Barrera, Francisco; Wijarnpreecha, Karn; Noureddin, Mazen; Alkhouri, Naim; Singal, Ashwani K.; Wong, Robert J.; Younossi, Zobair M.; Rinella, Mary E.; Kamath, Patrick S.; Bataller, Ramon; Loomba, Rohit; Arrese Jiménez, Marco; Arab Verdugo, Juan Pablo
    © The Author(s) 2024.Introduction: The 2023 nomenclature defined criteria for steatotic liver disease (SLD), including metabolic dysfunction-associated SLD (MASLD), alcohol-associated liver disease (ALD), and the overlapping MASLD/ALD (MetALD). We aimed to assess racial and ethnic disparities in the SLD prevalence among United States (US) adults based on this new nomenclature. Methods: We undertook a cross-sectional study employing the 2017–2018 National Health and Nutrition Examination Survey (NHANES) database. We identified SLD according to a controlled attenuation parameter ≥288 dB/m, liver stiffness ≥7.2 kPa, or elevated aminotransferase levels. Alcohol use thresholds were established according to the updated SLD definition. We estimated prevalences using the complex design of the NHANES survey. Multivariable logistic regressions with complex design weights were employed. Results: A total of 5532 individuals are included. The mean age is 45.4 years, and 50.9% are women. The adjusted estimated prevalence of MASLD is 42.4% (95% CI: 41.1–43.8%), MetALD 1.7% (95% CI: 1.3–2.0%), and ALD 0.6% (95% CI: 0.3–0.8%). Hispanics exhibit a higher prevalence of SLD, but there are no significant differences in advanced fibrosis prevalence due to SLD among racial/ethnic groups. In MASLD, men, individuals aged 40–64 and ≥65 years, Hispanics, those with health insurance, higher BMI, diabetes, hypertension, hypertriglyceridemia, and low high-density lipoprotein (HDL) cholesterol or use of lipid-lowering agents are independently associated with a higher risk, while Blacks have the lowest risk. In MetALD, men and higher BMI are independently associated with a higher risk of MetALD in adjusted multivariable analysis. In ALD, the adjusted multivariable analysis shows that only health insurance is independently associated with a lower ALD risk. Conclusions: MASLD prevalence is high in the US, especially in men, older individuals, and Hispanics. MetALD and ALD prevalence was substantial but could be underestimated.

    Global epidemiology of alcohol-associated liver disease in adolescents and young adults
    (2024) Danpanichkul, Pojsakorn; Chen, Vincent L.; Tothanarungroj, Primrose; Kaewdech, Apichat; Kanjanakot, Yatawee; Fangsaard, Panisara; Wattanachayakul, Phuuwadith; Duangsonk, Kwanjit; Kongarin, Siwanart; Yang, Ju Dong; Wong, Robert J.; Noureddin, Mazen; Diaz, Luis Antonio; Arab, Juan Pablo; Liangpunsakul, Suthat; Wijarnpreecha, Karn
    Background and AimsThe objective of the study was to analyse the prevalence, incidence, and death of alcohol-associated liver disease (ALD) among adolescents and young adults globally, continentally, and nationally, focusing on trends over time.MethodsThe study analysed data from the Global Burden of Disease (GBD) study between 2000 and 2019. It examined ALD's prevalence, incidence, and death in adolescents and young adults aged 15-29, segmented by region, nation, and sociodemographic index. The analysis utilised Joinpoint regression modelling to calculate the annual per cent change (APC) in the rate of these parameters over time.ResultsIn 2019, there were 281,450 ALD prevalences, 18,930 incidences, and 3190 deaths among adolescents and young adults globally. From 2000 to 2019, the age-adjusted prevalence rate per 100,000 increased in the 25-29 age group (APC: +0.6%, p = 0.003), remained stable among ages 20-24 (p = 0.302) and ages 15-19 (p = 0.160). Prevalence increased significantly from age 15-19 to 20-24 (19-fold increase) and from age 20-24 to 25-29 (2.5-fold increase). ALD prevalence rates increased in all age groups in adolescents and young adults in Africa and the Eastern Mediterranean region. Around three-quarters of countries and territories experienced an increase in ALD incidence rates in young adults.ConclusionOver two decades, the burden of ALD among adolescents and young adults has increased globally. The study emphasises the importance of public health policies aimed at reducing alcohol consumption and preventing ALD among younger populations.

    Racial and ethnic disparities in the natural history of alcohol-associated liver disease in the United States
    (WILEY, 2024) Ayares Campos, Gustavo Ignacio; Diaz Piga, Luis Antonio; Fuentes Lopez, Eduardo; Idalsoaga Ferrer, Francisco Javier; Cotter, Thomas G.; Dunn, Winston; Simonetto, Douglas; Shah, Vijay H.; Kamath, Patrick S.; Lazarus, Jeffrey V.; Bataller, Ramon; Arrese, Marco; Wong, Robert J.; Singal, Ashwani K.; Arab, Juan Pablo
    Background: Outcomes in alcohol-associated liver disease (ALD) are influenced by several race and ethnic factors, yet its natural history across the continuum of patients in different stages of the disease is unknown.MethodsWe conducted a retrospective cohort study of U.S. adults from 2011 to 2018, using three nationally representative databases to examine potential disparities in relevant outcomes among racial and ethnic groups. Our analysis included logistic and linear regressions, along with competing risk analysis.ResultsBlack individuals had the highest daily alcohol consumption (12.6 g/day) while Hispanic participants had the largest prevalence of heavy episodic drinking (33.5%). In a multivariable-adjusted model, Hispanic and Asian participants were independently associated with a higher ALD prevalence compared to Non-Hispanic White interviewees (OR: 1.4, 95% CI: 1.1-1.8 and OR: 1.5 95% CI:1.1-2.0, respectively), while Blacks participants had a lower ALD prevalence (OR: .7 95% CI: .6-.9), and a lower risk of mortality during hospitalization due to ALD (OR: .83 95% CI: .73-.94). Finally, a multivariate competing-risk analysis showed that Hispanic ethnicity had a decreased probability of liver transplantation if waitlisted for ALD (SHR: .7, 95% CI: .6-.8) along with female Asian population (HR: .40, 95% CI: .26-.62).ConclusionsAfter accounting for key social and biological health determinants, the Hispanic population showed an increased risk of ALD prevalence, even with lower alcohol consumption. Additionally, Hispanic and Asian female patients had reduced access to liver transplantation compared to other enlisted patients., image
