    Acute Liver Injury Among Pediatric Liver Transplantation Recipients With Coronavirus Disease 2019: An International Collaborative Study
    (2021) Sin, Priscila; Diaz, Luis Antonio; Martinez, Mercedes; Vizcaya, Cecilia; D'Agostino, Daniel; Gana, Juan Cristobal
    Coronavirus disease 2019 (COVID-19) is an ongoing pandemic. The occurrence of acute liver injury (ALI) has been reported in liver transplant (LT) recipients; however, the findings on children remain controversial. This is the first extensive, worldwide report on the impact of COVID-19 on pediatric LT recipients. Our online survey reported 110 pediatric LT recipients with severe acute respiratory syndrome coronavirus 2 infection. Of these, 37 were symptomatic and 20 out of them (54%) had complicated COVID-19, which included ALI and acute liver graft rejection. No mortality was reported. Pediatric LT recipients who had undergone transplantation less than 6 months before contracting COVID-19 had a greater number of hospital admissions and a higher ALI frequency (P = 0.013 and P = 0.033, respectively) than those who had undergone transplantation more than 6 months prior. Our study found that COVID-19 cases among pediatric LT recipients demonstrated a high complication rate. We propose that these patients must be followed up strictly.

    Alcohol-related liver disease: A global perspective
    (2024) Narro, Graciela Elia Castro; Diaz, Luis Antonio; Ortega, Eric Kauffman; Garin, Maria Fernanda Bautista; Reyes, Eira Cerda; Delfin, Pindaro Sebastian Martinez; Arab, Juan Pablo; Bataller, Ramon
    Alcohol-associated liver disease (ALD) represents one of the deadliest yet preventable consequences of excessive alcohol use. It represents 5.1 % of the global burden of disease, mainly involving the productive-age population (15-44 years) and leading to an increased mortality risk from traffic road injuries, suicide, violence, cardiovascular disease, neoplasms, and liver disease, among others, accounting for 5.3 % of global deaths. Daily alcohol consumption, binge drinking (BD), and heavy episodic drinking (HED) are the patterns associated with a higher risk of developing ALD. The escalating global burden of ALD, even exceeding what was predicted, is the result of a complex interaction between the lack of public policies that regulate alcohol consumption, low awareness of the scope of the disease, late referral to specialists, underuse of available medications, insufficient funds allocated to ALD research, and non-predictable events such as the COVID-19 pandemic, where increases of up to 477 % in online alcohol sales were registered in the United States. Early diagnosis, referral, and treatment are pivotal to achieving the therapeutic goal in patients with alcohol use disorder (AUD) and ALD, where complete alcohol abstinence and prevention of alcohol relapse are expected to enhance overall survival. This can be achieved through a combination of cognitive behavioral, motivational enhancement and pharmacological therapy. Furthermore, the appropriate use of available pharmacological therapy and implementation of public policies that comprehensively address this disease will make a real difference.

    Colorectal adenomas and MAFLD: a cross-sectional study in a Hispanic screening cohort
    (2022) Villalon, Alejandro; Diaz, Luis Antonio; Fuentes-Lopez, Eduardo; Villalon, Javier; Villalon, Fernando; Ayares, Gustavo; Yanez, Barbara; Candia, Roberto; Arab, Juan Pablo; Arrese, Marco
    Aims: Prior evidence demonstrates an association between non-alcoholic fatty liver disease (NAFLD) and colorectal adenomas (CRA) risk. However, information using the new definition of the disease [i.e., metabolic dysfunction-associated fatty liver disease (MAFLD)] is scarce. We aimed to assess the relationship between MAFLD and CRA risk. Methods: We conducted a cross-sectional study including patients from three university centers in Chile who underwent a colonoscopy for colorectal cancer screening and abdominal imaging study. We obtained sociodemographic and clinical data, and we performed univariate and multivariable regression analyses. Results: In total, 895 patients were included; 42% were male, the mean age was 59.9 +/- 9.3 years, and 37.8% (338) had CRA. Patients harboring polyps were predominantly males (48.2% vs . 38.2%, P = 0.002), older (61.6 +/- 8.7 years vs . 58.9 +/- 9.5 years, P < 0.001), and exhibited a higher body weight than controls [75 (66-88) kg vs . 72 (63-82.3) kg, P = 0.002]. Fifty-six percent of patients showed hepatic steatosis in imaging studies and 54.4% met MAFLD diagnostic criteria. The adenoma detection rate was higher in the MAFLD group compared to controls (46.4% vs . 27.5%, P < 0.001). In the multivariable analysis, MAFLD was significantly associated with the presence of CRA (odds ratio = 2.32; 95%CI: 1.68-3.19, P < 0.0001). There were no statistically significant differences of histopathological characteristics of the adenomas according to the presence of MAFLD. Conclusion: The present study shows that, in Chilean Hispanic subjects, MAFLD is associated with an increased risk of CRA. This information may be useful to design specific screening colonoscopy recommendations in MAFLD patients.

    Development and validation of nonalcoholic fatty liver disease test: a simple sensitive and specific marker for early diagnosis of nonalcoholic fatty liver disease
    (2023) Omran, Mohamed; Omr, Mona; Mohamed, Amal A.; Abdelghafour, Reem A.; Muharram, Nashwa M.; Hassan, Mohamed B.; Fangry, Abobakrelsedik; Emran, Tarek; Arab, Juan P.; Arnold, Jorge; Diaz, Luis Antonio; Zheng, Ming-Hua; El-Kassas, Mohamed
    AimThis study aimed to develop a noninvasive test for identifying patients with nonalcoholic fatty liver disease (NAFLD) based on clinical and routine laboratory data. MethodsThe developed model 'NAFLD test' was compared to the most commonly used NAFLD scores and then validated in three groups of NAFLD patients from five centers in Egypt, China, and Chile. Patients were divided into the discovery cohort (n = 212) and the validation study (n = 859). The ROC curve and stepwise multivariate discriminant analysis were used to develop and validate the NAFLD test and evaluate its diagnostic performance, which was then compared to other NAFLD scores. ResultsElevated C-reactive protein (CRP), cholesterol, BMI, and alanine aminotransferase (ALT) levels were significantly associated with NAFLD (P < 0.0001). NAFLD test is depicted as (-0.695 + 0.031 x BMI + 0.003 x cholesterol + 0.014 x ALT + 0.025 x CRP) to discriminate patients with NAFLD from healthy individuals. The area under the ROC curve (AUC) of the NAFLD test was 0.92 [95% confidence interval (CI): 0.88-0.96]. The NAFLD test was the most accurate diagnostic indicator of NAFLD when compared to widely used NAFLD indices. Upon validating the NAFLD test, its AUC (95% CI) for distinguishing patients with NAFLD from healthy individuals was 0.95 (0.94-0.97), 0.90 (0.87-0.93), and 0.94 (0.91-0.97) in Egyptian, Chinese, and Chilean patients with NAFLD respectively. ConclusionThe NAFLD test is a new validated diagnostic biomarker that can be utilized for the early diagnosis of NAFLD with high diagnostic performance.

    Disparities in metabolic dysfunction-associated steatotic liver disease and cardiometabolic conditions in low and lower middle-income countries: a systematic analysis from the global burden of disease study 2019
    (2024) Danpanichkul, Pojsakorn; Suparan, Kanokphong; Dutta, Priyata; Kaeosri, Chuthathip; Sukphutanan, Banthoon; Pang, Yanfang; Kulthamrongsri, Narathorn; Jaisa-aad, Methasit; Ng, Cheng Han; Teng, Margaret; Nakano, Masahito; Morishita, Asahiro; Alkhouri, Naim; Yang, Ju Dong; Chen, Vincent L.; Kim, Donghee; Fallon, Michael B.; Diaz, Luis Antonio; Arab, Juan Pablo; Mantzoros, Christos S.; Noureddin, Mazen; Lazarus, Jeffrey, V; Wijarnpreecha, Karn
    Objective: Metabolic dysfunction-associated steatotic liver disease (MASLD) and cardiometabolic conditions affect populations across economic strata. Nevertheless, there are limited epidemiological studies addressing these diseases in low (LICs) and lower-middle-income countries (lower MICs). Therefore, an analysis of the trend of MASLD and cardiometabolic conditions in these countries is necessary. Methods: From 2000 to 2019, jointpoint regression analysis was employed to calculate the prevalence, mortality, and disability-adjusted life years (DALYs) for cardiometabolic conditions including MASLD, type 2 diabetes mellitus (T2DM), dyslipidemia (DLP), hypertension (HTN), obesity, peripheral artery disease (PAD), atrial fibrillation and flutter (AF/AFL), ischemic heart disease (IHD), stroke, and chronic kidney disease from HTN and T2DM, in LICs and lower MICs (according to the World Bank Classification 2019) using the Global Burden of Disease 2019 data. Results: Among the eleven cardiometabolic conditions, MASLD (533.65 million), T2DM (162.96 million), and IHD (76.81 million) had the highest prevalence in LICs and Lower MICs in 2019. MASLD represented the largest proportion of global prevalence in these countries (43 %). From 2000 to 2019, mortality in LICs and lower MICs increased in all cardiometabolic conditions, with obesity-related mortality having the highest increase ( +134 %). During this timeframe, there were increased age-standardized death rates (ASDR) from obesity, PAD, and AF/ AFL. From all conditions, the DALYs-to-prevalence ratio was higher in LICs and lower MICs than the global average. Conclusion: The burden of MASLD and cardiometabolic conditions is increasing worldwide, with LICs and lower MICs experiencing higher (DALYs) disability per prevalence. As these conditions are preventable, counteracting these trends requires not only the modification of ongoing actions but also the strategizing of immediate interventions.

    Global and regional burden of alcohol-associated liver disease and alcohol use disorder in the elderly
    (2024) Danpanichkul, Pojsakorn; Suparan, Kanokphong; Ng, Cheng Han; Dejvajara, Disatorn; Kongarin, Siwanart; Panpradist, Nuttada; Chaiyakunapruk, Nathorn; Muthiah, Mark D.; Chen, Vincent L.; Huang, Daniel Q.; Diaz, Luis Antonio; Noureddin, Mazen; Arab, Juan Pablo; Wijarnpreecha, Karn
    Background & Aims: Alcohol -associated liver diseases (ALDs) and alcohol use disorder (AUD) pose a global health risk. AUD is underrecognized in the elderly, and the burden of AUD complications, including ALD, may increase with aging populations and rising alcohol intake. However, there is a lack of epidemiological evidence on AUD and ALD in the elderly. Methods: Using the Global Burden of Disease Study 2019, we analyzed the prevalence, mortality, disability -adjusted life years (DALYs), age -standardized rates (ASRs), and temporal change from 2000 to 2019 of ALD and AUD in the overall population and the elderly (65-89 years). The findings were categorized by sex, region, nation, and sociodemographic index. Results: The prevalence rates of ALD in the elderly were higher than those in adolescents and young adults, whereas AUD levels were lower than those in adolescents and young adults. In 2019, there were 9.39 million cases (8.69% of cases in the overall population) of AUD, 3.23 million cases (21.8% of cases in the overall population) of alcohol -associated cirrhosis, and 68,468 cases (51.27% of cases in the overall population) of liver cancer from alcohol among the elderly. ASRs of the prevalence of ALD and AUD in the elderly increased in most regions; on the contrary, ASRs of death and DALYs decreased in most regions. Nevertheless, ASRs of death and DALYs from liver cancer from alcohol increased in many areas. Conclusions: Our findings highlighted the increased prevalence of ALD in the elderly, with a burden of AUD comparable with that in the overall population. Public health strategies on ALD and AUD targeting the elderly are urgently needed. Impact and implications: The burden of alcohol -associated liver disease (ALD) and alcohol use disorder (AUD) is increasing. Advances in healthcare and education have resulted in a remarkable spike in life expectancy and a consequential population aging. Nevertheless, little is known about the epidemiology of ALD and AUD in the elderly. Our study indicates the increasing burden of ALD and AUD in the elderly population, necessitating early detection, intervention, and tailored care to the unique needs and complexities faced by older individuals grappling with these conditions.

    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.

    Background: Severe alcohol-associated hepatitis (sAH) is a well-characterized disease with high short-term mortality. However, there is limited research on those with a "less severe condition" (moderate AH). This study aims to characterize in-depth patients with moderate AH (mAH), including the performance of mortality scoring systems, key prognostic factors, and survival over time. Methods:A multicenter retrospective cohort study (2009-2019) included patients with mAH (MELD score <= 20 at admission). Cox regression and receiver operating characteristic curves with AUC were used for analysis. Results:We included 1845 patients with AH (20 centers, 8 countries) between 2009 and 2019. mAH was defined as a MELD score <= 20 at admission. Twenty-four percent met the criteria for an mAH episode. Patients with mAH tend to be older and have a higher proportion of females, with a median MELD of 17 (15-19), Maddrey discriminant function (mDF) of 33 (22-40), the trajectory of serum bilirubin of 0.83 (0.60-1.21), and neutrophil-to-lymphocyte ratio (NLR) of 5 (2.96-8.60). The primary causes of death in mAH included multiple organ failure (34.1%) and infections (16.6%). The cumulative survival rates at 30, 90, and 180 days were 94.3%, 90.4%, and 88.2%, respectively. In multivariable analysis, age was the only significant predictor of 30-day mortality (HR 1.49, 95% CI: 1.27-1.76, p<0.001). Mortality prediction models showed poor performance, with AUC for MELD (0.671), mDF (0.726), trajectory of serum bilirubin (0.733), and NLR (0.697). Conclusions:Patients with moderate AH exhibited a mortality of 11.8% at 6 months, primarily driven by multiple organ failure and infections. These patients also exhibit a different clinical profile compared to those with sAH. Tailored models and therapeutic strategies are needed to improve long-term outcomes in mAH.

    Racial and ethnic disparities in alcohol-associated liver disease in the United States: A systematic review and meta-analysis
    (2024) Anouti, Ahmad; El Dahan, Karim Seif; Rich, Nicole E.; Louissaint, Jeremy; Lee, William M.; Lieber, Sarah R.; Arab, Juan Pablo; Zhang, Bill Y.; Patel, Mausam J.; Thimphittaya, Chanattha; Diaz, Luis Antonio; Gregory, Dyanna L.; Kozlitina, Julia; Vanwagner, Lisa B.; King, Andrea C.; Mitchell, Mack C.; Singal, Amit G.; Cotter, Thomas G.
    Background:Alcohol-associated liver disease (ALD), encompassing alcohol-associated hepatitis and alcohol-associated cirrhosis, is rising in the United States. Racial and ethnic disparities are evident within ALD; however, the precise nature of these disparities is poorly defined.Methods:We conducted a search of the PubMed/MEDLINE and EMBASE databases to identify studies published from inception through September 2023 that reported ALD incidence, prevalence, and mortality within the United States, stratified by race and ethnicity. We calculated pooled prevalence and incidence by race and ethnicity, including risk ratios and ORs for ALD pooled prevalence and alcohol-associated hepatitis/alcohol-associated cirrhosis pooled proportions, and OR for ALD mortality using the DerSimonian and Laird method for random-effect models.Results:We identified 25 relevant studies (16 for quantitative meta-analysis), comprising 76,867,544 patients. ALD prevalence was highest in Hispanic (4.5%), followed by White (3.1%) and Black (1.4%) individuals. Pooled risk ratios of ALD prevalence were 1.64 (95% CI: 1.12-2.39) for Hispanic and 0.59 (95% CI: 0.35-0.87) for Black compared to White individuals. Mortality among those with ALD did not significantly differ between White and Hispanic (OR: 1.54, 95% CI: 0.9-2.5; I 2=0%), Black (OR: 1.2, 95% CI: 0.8-1.6; I 2=0%), or Native American (OR: 2.41, 95% CI: 0.9-2.9) individuals, while there was a significant difference between White and Asian (OR: 0.1; 95% CI: 0.03-0.5) individuals. Most data were cross-sectional and assessed to be of poor or fair quality.Conclusions:Differences were observed in ALD epidemiology, including higher prevalence among Hispanic and lower prevalence among Black individuals, although there were smaller differences in ALD mortality. Differences in ALD prevalence and prognosis remain poorly defined based on existing data, highlighting a need for higher-quality epidemiological studies in this area.

    Racial and Ethnic Disparities in Liver Transplantation for Alcohol-associated Liver Diseases in the United States
    (2024) Cotter, Thomas G.; Mitchell, Mack C.; Patel, Mausam J.; Anouti, Ahmad; Lieber, Sarah R.; Rich, Nicole E.; Arab, Juan Pablo; Diaz, Luis Antonio; Louissaint, Jeremy; Kerr, Thomas; Mufti, Arjmand R.; Hanish, Steven I.; Vagefi, Parsia A.; Patel, Madhukar S.; Vanwagner, Lisa B.; Lee, William M.; OLeary, Jacqueline G.; Singal, Amit G.
    Background.Emerging data suggest disparities exist in liver transplantation (LT) for alcohol-associated liver disease (ALD). As the incidence of ALD increases, we aimed to characterize recent trends in ALD LT frequency and outcomes, including racial and ethnic disparities.Methods.Using United Network for Organ Sharing/Organ Procurement and Transplantation Network data (2015 through 2021), we evaluated LT frequency, waitlist mortality, and graft survival among US adults with ALD (alcohol-associated hepatitis [AH] and alcohol-associated cirrhosis [AAC]) stratified by race and ethnicity. We used adjusted competing-risk regression analysis to evaluate waitlist outcomes, Kaplan-Meier analysis to illustrate graft survival, and Cox proportional hazards modeling to identify factors associated with graft survival.Results.There were 1211 AH and 26 526 AAC new LT waitlist additions, with 970 AH and 15 522 AAC LTs performed. Compared with non-Hispanic White patients (NHWs) with AAC, higher hazards of waitlist death were observed for Hispanic (subdistribution hazard ratio [SHR] = 1.23, 95% confidence interval [CI]: 1.16-1.32), Asian (SHR = 1.22, 95% CI:1. 01-1.47), and American Indian/Alaskan Native (SHR = 1.42, 95% CI: 1.15-1.76) candidates. Similarly, significantly higher graft failures were observed in non-Hispanic Black (HR = 1.32, 95% CI: 1.09-1.61) and American Indian/Alaskan Native (HR = 1.65, 95% CI: 1.15-2.38) patients with AAC than NHWs. We did not observe differences in waitlist or post-LT outcomes by race or ethnicity in AH, although analyses were limited by small subgroups.Conclusions.Significant racial and ethnic disparities exist for ALD LT frequency and outcomes in the United States. Compared with NHWs, racial and ethnic minorities with AAC experience increased risk of waitlist mortality and graft failure. Efforts are needed to identify determinants for LT disparities in ALD that can inform intervention strategies.

    Socio-economic association of alcohol use disorder and cardiovascular and alcohol-associated liver disease from 2010 to 2019
    (2024) Danpanichkul, Pojsakorn; Chen, Vincent L.; Chaiyakunapruk, Nathorn; Auttapracha, Thanida; Kongarin, Siwanart; Ng, Cheng Han; Duangsonk, Kwanjit; Muthiah, Mark D.; Sukphutanan, Banthoon; Sim, Benedix; Huang, Daniel Q.; Seko, Yuya; Lee, Brian P.; Takahashi, Hirokazu; Noureddin, Mazen; Lazarus, Jeffrey V.; Diaz, Luis Antonio; Arab, Juan Pablo; Mellinger, Jessica Leigh; Liangpunsakul, Suthat; Wijarnpreecha, Karn
    Backgrounds and AimsAlcohol use leads to disabilities and deaths worldwide. It not only harms the liver but also causes alcohol use disorder (AUD) and heart disease. Additionally, alcohol consumption contributes to health disparities among different socio-economic groups.MethodsWe estimated global and regional trends in the burden of AUD, liver disease, and cardiovascular disease from alcohol using the methodology of the Global Burden of Disease study.ResultsIn 2019, the highest disability-adjusted life years rate per 100,000 population was due to AUD (207.31 [95% Uncertainty interval (UI) 163.71-261.66]), followed by alcohol-associated liver disease (ALD) (133.31 [95% UI 112.68-156.17]). The prevalence rate decreased for AUD (APC [annual percentage change] -0.38%) and alcohol-induced cardiomyopathy (APC -1.85%) but increased for ALD (APC 0.44%) and liver cancer (APC 0.53%). Although the mortality rate for liver cancer from alcohol increased (APC 0.30%), mortality rates from other diseases decreased. Between 2010 and 2019, the burden of alcohol-associated complications increased in countries with low and low-middle sociodemographic index (SDI), contributing more significantly to the global burden.ConclusionThe global burden of AUD, liver, and cardiovascular disease has been high and increasing over the past decade, particularly for liver complications. Lower SDI countries are contributing more to this global burden. There is a pressing need for effective strategies to address this escalating burden.

    The burden of liver disease in Latin America
    (2024) Diaz, Luis Antonio; Villota-Rivas, Marcela; Barrera, Francisco; V. Lazarus, Jeffrey; Arrese, Marco
    Liver disease poses a substantial burden in Latin America. This burden is primarily attributed to a high level of alcohol consumption and the increasing prevalence of risk factors associated with metabolic dysfunctionassociated steatotic liver disease (MASLD), such as sedentary lifestyles, easy access to ultra-processed foods, obesity, and type 2 diabetes mellitus. These epidemiological trends are cause for concern, especially considering that there are significant challenges in addressing them due to disparities in access to liver disease screening and care. In this article, we aim to provide an overview of the current situation regarding liver disease in Latin America. We also discuss recent multinational proposals designed to address the growing MASLD burden via its integration into existing non-communicable diseases policies, at both local and global levels. Additionally, we emphasize the urgent need to establish effective public health policies that target both MASLD risk factors and excessive alcohol consumption. Furthermore, we discuss the development of liver transplantation programs, areas for improvement in medical education and research capabilities, and how the fostering of extensive collaboration among all stakeholders is crucial for addressing liver disease in the region.
