    (Elsevier B.V., 2023) Diaz Piga, Luis Antonio; Fuentes, López Eduardo; Idalsoaga Ferrer, Francisco Javier; Ayares Campos, Gustavo Ignacio; Corsi Sotelo, Oscar Felipe; Arnold Alvarez, Jorge Ignacio; Cannistra Cadiz, Macarena Rossella; Vio Quiroz, Danae Fernanda; Marquez Lomas, Andrea; Ramirez Cadiz, Carolina Andrea; Medel Salas, María Paz; Hernández Tejero, María; Ferreccio Readi, Fresia Catterina; Lazo Bravo, Mariana Carolina; Roblero Cum, Juan Pablo; Cotter, Thomas G.; Kulkarni ,Anand V.; Kim, Won; Brahmania, Mayur; Louvet, Alexandre; Tapper, Elliot B.; Dunn, Winston; Simonetto, Douglas; Shah, Vijay H.; Kamath, Patrick S.; Lazarus, Jeffrey V.; Singal, Ashwabi K.; Bataller, Ramón; Arrese Jimenez, Marco Antonio; Arab Verdugo, Juan Pablo
    © 2023 The Author(s)Background & Aims: The long-term impact of alcohol-related public health policies (PHPs) on disease burden is unclear. We aimed to assess the association between alcohol-related PHPs and alcohol-related health consequences. Methods: We conducted an ecological multi-national study including 169 countries. We collected data on alcohol-related PHPs from the WHO Global Information System of Alcohol and Health 2010. Data on alcohol-related health consequences between 2010–2019 were obtained from the Global Burden of Disease database. We classified PHPs into five items, including criteria for low, moderate, and strong PHP establishment. We estimated an alcohol preparedness index (API) using multiple correspondence analysis (0 lowest and 100 highest establishment). We estimated an incidence rate ratio (IRR) for outcomes according to API using adjusted multilevel generalized linear models with a Poisson family distribution. Results: The median API in the 169 countries was 54 [IQR 34.9–76.8]. The API was inversely associated with alcohol use disorder (AUD) prevalence (IRR 0.13; 95% CI 0.03–0.60; p = 0.010), alcohol-associated liver disease (ALD) mortality (IRR 0.14; 95% CI 0.03–0.79; p = 0.025), mortality due to neoplasms (IRR 0.09; 95% CI 0.02–0.40; p = 0.002), alcohol-attributable hepatocellular carcinoma (HCC) (IRR 0.13; 95% CI 0.02–0.65; p = 0.014), and cardiovascular diseases (IRR 0.09; 95% CI 0.02–0.41; p = 0.002). The highest associations were observed in the Americas, Africa, and Europe. These associations became stronger over time, and AUD prevalence was significantly lower after 2 years, while ALD mortality and alcohol-attributable HCC incidence decreased after 4 and 8 years from baseline API assessment, respectively (p <0.05). Conclusions: The API is a valuable instrument to quantify the robustness of alcohol-related PHP establishment. Lower AUD prevalence and lower mortality related to ALD, neoplasms, alcohol-attributable HCC, and cardiovascular diseases were observed in countries with a higher API. Our results encourage the development and strengthening of alcohol-related policies worldwide. Impact and implications: We first developed an alcohol preparedness index, an instrument to assess the existence of alcohol-related public policies for each country. We then evaluated the long-term association of the country's alcohol preparedness index in 2010 with the burden of chronic liver disease, hepatocellular carcinoma, other neoplasms, and cardiovascular disease. The strengthening of alcohol-related public health policies could impact long-term mortality rates from cardiovascular disease, neoplasms, and liver disease. These conditions are the main contributors to the global burden of disease related to alcohol use. Over time, this association has not only persisted but also grown stronger. Our results expand the preliminary evidence regarding the importance of public health policies in controlling alcohol-related health consequences.

    (2008) Zuñiga, Silvia Eugenia; Molina, Héctor; Azócar, Lorena; Amigo Boker, Ludwig Peter; Nervi Oddone, Flavio; Pimentel Muller, Fernando Ernesto; Jarufe Cassis, Nicolas Patricio; Arrese Jimenez, Marco Antonio; Lammert, Frank; Miquel Poblete, Juan Francisco
    Background: Intestinal cholesterol absorption may influence gallstone formation and its modulation could be a useful therapeutic strategy for gallstone disease (GSD). Ezetimibe (EZET) is a cholesterol-lowering agent that specifically inhibits intestinal cholesterol absorption. Aims: To test whether EZET can prevent gallstone formation in mice. Methods/Results: Gallstone-susceptible C57BL/6 inbred mice were fed control and lithogenic diets with or without simultaneous EZET administration. Lithogenic diet increased biliary cholesterol content and secretion, and induced sludge or gallstone formation in 100% of the animals. EZET administration reduced intestinal cholesterol absorption by 90% in control animals and by 35% in mice receiving the lithogenic diet. EZET prevented the appearance of cholesterol crystals and gallstones. In addition, mice fed the lithogenic diet plus EZET exhibited a 60% reduction in biliary cholesterol saturation index. Of note, EZET treatment caused a significant increase in bile flow (+50%, P < 0.01) as well as bile salt, phospholipid and glutathione secretion rates (+60%, +44% and +100%, respectively, P < 0.01), which was associated with a moderately increased expression of hepatic bile salt transporters. In addition, relative expression levels of Nieman-Pick C1 like 1 (NPC1L1) in the enterohepatic axis in humans were assessed. Expression levels of NPC1L1 were 15-to 30-fold higher in the duodenum compared with the liver at transcript and protein levels, respectively, suggesting preferential action of EZET on intestinal cholesterol absorption in humans. Conclusions: In a murine model of GSD, EZET prevented gallstone formation by reducing intestinal cholesterol absorption and increasing bile salt-dependent and -independent bile flow. EZET could be useful in preventing GSD disease in susceptible patients.

    Impact of Public Health Policies on Alcohol-Associated Liver Disease in Latin America: An Ecological Multinational Study
    (WILEY, 2021) Diaz Piga, Luis Antonio; Idalsoaga Ferrer, Francisco Javier; Fuentes López, Eduardo; Marquez Lomas, Andrea; Ramirez, Carolina A.; Pablo Roblero, Juan; Araujo, Roberta C.; Higuera de la Tijera, Fatima; Guillermo Toro, Luis; Pazmino, Galo; Montes, Pedro; Hernandez, Nelia; Mendizabal, Manuel; Corsi, Oscar; Ferreccio, Catterina; Lazo, Mariana; Brahmania, Mayur; Singal, Ashwani K.; Bataller, Ramon; Arrese Jimenez, Marco Antonio; Arab Verdugo, Juan Pablo
    Background and Aims Alcohol-associated liver disease (ALD) is the leading cause of liver-related mortality in Latin America, yet the impact of public health policies (PHP) on liver disease is unknown. We aimed to assess the association between alcohol PHP and deaths due to ALD in Latin American countries. Approach and Results We performed an ecological multinational study including 20 countries in Latin America (628,466,088 inhabitants). We obtained country-level sociodemographic information from the World Bank Open Data source. Alcohol-related PHP data for countries were obtained from the World Health Organization Global Information System of Alcohol and Health. We constructed generalized linear models to assess the association between the number of PHP (in 2010) and health outcomes (in 2016). In Latin America, the prevalence of obesity was 27% and 26.1% among male and female populations, respectively. The estimated alcohol per capita consumption among the population at 15 years old or older was 6.8 L of pure alcohol (5.6 recorded and 1.2 unrecorded). The overall prevalence of alcohol use disorders (AUD) was 4.9%. ALD was the main cause of cirrhosis in 64.7% of male and 40.0% of female populations. A total of 19 (95%) countries have at least one alcohol-related PHP on alcohol. The most frequent PHP were limiting drinking age (95%), tax regulations (90%), drunk-driving policies and countermeasures (90%), and government monitoring systems and community support (90%). A higher number of PHP was associated with a lower ALD mortality (PR, 0.76; 95% CI, 0.61-0.93; P = 0.009), lower AUD prevalence (PR, 0.80; 95% CI, 0.65-0.99; P = 0.045), and lower alcohol-attributable road traffic deaths (PR, 0.81; 95% CI, 0.65-1.00; P = 0.051). Conclusions Our study indicates that in Latin America, countries with higher number of PHP have lower mortality due to ALD, lower prevalence of AUD, and lower alcohol-attributable road traffic mortality.

    © 2023 The Author(s)Background & Aims: Model for End-Stage Liver Disease (MELD) score better predicts mortality in alcohol-associated hepatitis (AH) but could underestimate severity in women and malnourished patients. Using a global cohort, we assessed the ability of the MELD 3.0 score to predict short-term mortality in AH. Methods: This was a retrospective cohort study of patients admitted to hospital with AH from 2009 to 2019. The main outcome was all-cause 30-day mortality. We compared the AUC using DeLong's method and also performed a time-dependent AUC with competing risks analysis. Results: A total of 2,124 patients were included from 28 centres from 10 countries on three continents (median age 47.2 ± 11.2 years, 29.9% women, 71.3% with underlying cirrhosis). The median MELD 3.0 score at admission was 25 (20–33), with an estimated survival of 73.7% at 30 days. The MELD 3.0 score had a better performance in predicting 30-day mortality (AUC:0.761, 95%CI:0.732–0.791) compared with MELD sodium (MELD-Na; AUC: 0.744, 95% CI: 0.713–0.775; p = 0.042) and Maddrey's discriminant function (mDF) (AUC: 0.724, 95% CI: 0.691–0.757; p = 0.013). However, MELD 3.0 did not perform better than traditional MELD (AUC: 0.753, 95% CI: 0.723–0.783; p = 0.300) and Age-Bilirubin-International Normalised Ratio-Creatinine (ABIC) (AUC:0.757, 95% CI: 0.727–0.788; p = 0.765). These results were consistent in competing-risk analysis, where MELD 3.0 (AUC: 0.757, 95% CI: 0.724–0.790) predicted better 30-day mortality compared with MELD-Na (AUC: 0.739, 95% CI: 0.708–0.770; p = 0.028) and mDF (AUC:0.717, 95% CI: 0.687–0.748; p = 0.042). The MELD 3.0 score was significantly better in predicting renal replacement therapy requirements during admission compared with the other scores (AUC: 0.844, 95% CI: 0.805–0.883). Conclusions: MELD 3.0 demonstrated better performance compared with MELD-Na and mDF in predicting 30-day and 90-day mortality, and was the best predictor of renal replacement therapy requirements during admission for AH. However, further prospective studies are needed to validate its extensive use in AH. Impact and implications: Severe AH has high short-term mortality. The establishment of treatments and liver transplantation depends on mortality prediction. We evaluated the performance of the new MELD 3.0 score to predict short-term mortality in AH in a large global cohort. MELD 3.0 performed better in predicting 30- and 90-day mortality compared with MELD-Na and mDF, but was similar to MELD and ABIC scores. MELD 3.0 was the best predictor of renal replacement therapy requirements. Thus, further prospective studies are needed to support the wide use of MELD 3.0 in AH.

    (Elsevier España, 2011) Espino Espino, Alberto Antonio; Villagran Torres, Andrea Alejandra; Vollrath Reyes, Valeska Yolanda; Hanckes Mayo, Maria Paulina; Salas Ocaranza, Roberto Ignacio; Farah Samaan, Andrea Catherina; Solis, Nancy; Pizarro Rojas, Margarita Alicia; Escalona Perez, Alex Gamaliel; Boza Wilson, Camilo; Perez, Gustavo; Carrasco, Gonzalo; Padilla, Orlando; Francisco Miguel, Juan; Nervi Oddone, Flavio; Chavez Tapia, Norberto C.; Arab Verdugo, Juan Pablo; Alvarez Lobos, Manuel Marcelo; Arrese Jimenez, Marco Antonio; Riquelme Perez, Arnoldo Javier
    Background. The plasminogen activator inhibitor type-1 (PAI-1) has been implicated in the regulation of fibrinolysis and extracellular matrix components. The single base pair guanine insertion/deletion polymorphism (4G/5G) within the promoter region of the PAI-1 gene influences PAI-1 synthesis and may modulate hepatic fibrogenesis. Aim. To evaluate the influence of PAI-1 serum levels and 4G/5G polymorphism on the risk of liver fibrosis associated to non-alcoholic fatty liver disease (NAFLD) in morbidly obese patients. Material and methods. Case-control study of 50 obese patients undergoing bariatric surgery and 71 non-obese subjects matched by age and sex. Anthropometric and biochemical measurements were performed, including PAI-1 serum levels. Genomic DNA was obtained to assess the presence of 4G/5G polymorphism. Results. BMI, insulinemia, triglycerides, HOMA-IR, hypertension and diabetes were significantly higher in obese patients compared to control subjects. PAI-1 serum levels observed in obese patients were significantly lower (10.63 +/- 4.82) compared to controls (14.26 +/- 11.4; p < 0.05). No differences were observed in the PAI-1 4G/5G promoter genotypes frequencies (p = 0.12). No differences were observed in PAI-1 plasma levels among obese patients with liver fibrosis (10.64 +/- 4.35) compared to patients without liver fibrosis (10.61 +/- 5.2; p = 0.985). PAI-1 4G/5G promoter genotypes frequencies were similar in patients with or without liver fibrosis associated to NASH (p = 0.6). Conclusions. Morbidly obese patients had significantly Lower PAI-1 serum levels with similar PAI-1 4G/5G genotypes frequencies compared to non-obese subjects. The frequency of 4G/5G genotypes in Chilean Hispanic healthy subjects was similar to that described in other populations. No association was found between PAI-1 serum levels or 4G/5G genotype with liver fibrosis in obese patients.

    Review article: Oesophageal disorders in chronic liver disease
    (WILEY, 2024) Idalsoaga Ferrer, Francisco Javier; Diaz Piga, Luis Antonio; Ayares Campos, Gustavo Ignacio; Cabrera, Daniel; Chahuan Abde, Javier Nicolas; Monrroy Bravo, Hugo Alfonso; Halawi, Houssam; Arrese Jimenez, Marco Antonio; Arab Verdugo, Juan Pablo
    Background: Oesophageal disorders and chronic liver disease are common worldwide and significantly impact quality of life. The intricate link between these conditions, including how oesophageal disorders like GERD, Barrett's oesophagus and oesophageal cancer affect and are affected by chronic liver disease, remains poorly understood. Aims: To review the relationship between oesophageal disorders and chronic liver disease, evaluating epidemiology, pathophysiology and therapeutic factors. Methods: We reviewed the literature on the relationship between oesophageal disorders and chronic liver disease, including cirrhosis, using the PubMed database Results: Oesophageal disorders such as gastroesophageal reflux disease, Barrett's oesophagus, oesophageal cancer, oesophageal motor disorders and oesophageal candidiasis are prevalent among individuals with cirrhosis, exacerbating the burden of liver disease. These diseases have a multifaceted symptomatology and pathogenic basis, posing a significant challenge in cirrhotic patients that necessitates careful diagnosis and management. Additionally, therapies frequently used for these diseases, such as proton pump inhibitors, require careful consideration in cirrhotic patients due to potential adverse effects and altered pharmacokinetics. Managing oesophageal disorders in cirrhotic patients requires a cautious approach due to possible interactions with medications and the risk of adverse effects. Furthermore, symptoms associated with these conditions are often exacerbated by common interventions in patients with cirrhosis, such as band ligation for oesophageal varices. Conclusions: Oesophageal disorders are common in cirrhosis and increase the disease burden. These conditions require careful management due to complex symptoms and treatment risks. Proton pump inhibitors and other therapies must be used cautiously, as cirrhosis interventions can worsen symptoms.

    (2019) Quezada González, José Luis; Cancino, Alejandra; Arrese Jimenez, Marco Antonio; Wolff, Rodrigo; Benitez Gajardo, Carlos Esteban; Pattillo Silva, Juan Carlos; Gana Ansaldo, Juan Cristobal; Concha Pinto, Mario Rodrigo; Cortinez Fernandez, Luis Ignacio; Vera Alarcón, María Magdalena; Miranda, Paula; Rubilar, Francisco; Troncoso, Andrés; Briceno Valenzuela, Eduardo Andres; Dib Marambio, Martin Javier; Jarufe Cassis, Nicolas Patricio; Martínez, Jorge; Guerra Castro, Juan Francisco
    Liver transplantation (LT) is an option for people with liverfailure who cannot be cured with other therapies and for some people with liver cancer. Aim: To describe, and analyze the first 300 LT clinical results, andto establish our learning curve. Material and Methods: Retrospective cohortstudy with data obtained from a prospectively collected LT Program database.We included all LT performed at a single center from March 1994 to September2017. The database gathered demographics, diagnosis, indications for LT, surgicalaspects and postoperative courses. We constructed a cumulative summation testfor learning curve (LC-CUSUM) using 30-day post-LT mortality. Mortality at 30days, and actuarial 1-, and 5-year survival rate were analyzed. Results: A total of281 patients aged 54 (0-71) years (129 women) underwent 300 LT. Ten percentof patients were younger than 18 years old. The first, second and third indicationsfor LT were non-alcoholic steatohepatitis, chronic autoimmune hepatitis andalcoholic liver cirrhosis, respectively. Acute liver failure was the LT indication in51 cases (17%). The overall complication rate was 71%. Infectious and biliarycomplications were the most common of them (47 and 31% respectively). TheLC-CUSUM curve shows that the first 30 patients corresponded to the learningcurve. The peri-operative mortality was 8%. Actuarial 1 and 5-year survival rateswere 82 and 71.4%, respectively. Conclusions: Outcome improvement of a LTprogram depends on the accumulation of experience after the first 30 transplantsand the peri-operative mortality directly impacted long-term survival.
