    Drug-induced liver injury: A management position paper from the Latin American Association for Study of the liver
    (2021) Bessone, Fernando; Hernandez, Nelia; Tagle, Martin; Arrese, Marco; Parana, Raymundo; Mendez-Sanchez, Nahum; Ridruejo, Ezequiel; Mendizabal, Manuel; Dagher, Lucy; Contreras, Fernando; Fassio, Eduardo; Pessoa, Mario; Brahm, Javier; Silva, Marcelo
    Idiosyncratic drug-induced liver injury (DILI) caused by xenobiotics (drugs, herbals and dietary supplements) is an uncommon cause of liver disease presenting with a wide range of phenotypes and disease severity, acute hepatitis mimicking viral hepatitis to autoimmune hepatitis, steatosis, fibrosis or rare chronic vascular syndromes. Disease severity ranges from asymptomatic liver test abnormalities to acute liver failure. DILI has been traditionally classified in predictable or intrinsic (dose-related) or unpredictable (not dose-related) mechanisms. Few prospective studies are assessing the real prevalence and incidence of hepatotoxicity in the general population. DILI registries represent useful networks used for the study of liver toxicity, aimed at improving the understanding of causes, phenotypes, natural history, and standardized definitions of hepatotoxicity. Although most of the registries do not carry out population-based studies, they may provide important data related to the prevalence of DILI, and also may be useful to compare features from different countries. With the support of the Spanish Registry of Hepatotoxicity, our Latin American Registry (LATINDILI) was created in 2011, and more than 350 DILI patients have been recruited to date. This position paper describes the more frequent drugs and herbsinduced DILI in Latin America, mainly focusing on several features of responsible medicaments. Also, we highlighted the most critical points on the management of hepatotoxicity in general and those based on findings from our Latin American experience in particular.

    (2019) Younossi, Zobair M.; Stepanova, Maria; Ong, Janus; Yilmaz, Yusuf; Duseja, Ajay; Eguchi, Yuichiro; El Kassas, Mohamed; Castellanos-Fernandez, Marlen; George, Jacob; Jacobson, Ira M.; Bugianesi, Elisabetta; Wong, Vincent Wai-Sun; Arrese, Marco; de Ledinghen, Victor; Romero-Gomez, Manuel; Mendez-Sanchez, Nahum; Ahmed, Aijaz; Wong, Robert; Papatheodoridis, Georgios; Serfaty, Lawrence; Younossi, Issah; Nader, Fatema; Ziayee, Mariam; Afendy, Arian
    BACKGROUND & AIMS: Non-alcoholic and alcohol-related fatty liver disease are overlapping diseases in which metabolic syndrome and alcohol consumption each contribute to progressive liver disease. We aimed to assess the effects of alcohol consumption and metabolic syndrome on mortality in individuals with fatty liver.

    Latin American Association for the study of the liver (ALEH) practice guidance for the diagnosis and treatment of non-alcoholic fatty liver disease

    Non-alcoholic fatty liver disease (NAFLD) currently represents an epidemic worldwide. NAFLD is the most frequently diagnosed chronic liver disease, affecting 20-30% of the general population. Furthermore, its prevalence is predicted to increase exponentially in the next decades, concomitantly with the global epidemic of obesity, type 2 diabetes mellitus (T2DM), and sedentary lifestyle. NAFLD is a clinical syndrome that encompasses a wide spectrum of associated diseases and hepatic complications such as hepatocellular carcinoma (HCC). Moreover, this disease is believed to become the main indication for liver transplantation in the near future. Since NAFLD management represents a growing challenge for primary care physicians, the Asociacion Latinoamericana para el Estudio del Higado (ALEH) has decided to organize this Practice Guidance for the Diagnosis and Treatment of Non-Alcoholic Fatty Liver Disease, written by Latin-American specialists in different clinical areas, and destined to general practitioners, internal medicine specialists, endocrinologists, diabetologists, gastroenterologists, and hepatologists. The main purpose of this document is to improve patient care and awareness of NAFLD. The information provided in this guidance may also be useful in assisting stakeholders in the decision-making process related to NAFLD. Since new evidence is constantly emerging on different aspects of the disease, updates to this guideline will be required in future.

    NAFLD: Challenges and opportunities to address the public health problem in Latin America
    (2021) Pablo, Arab Juan; Antonio, Diaz Luis; Melisa, Dirchwolf; Mark, Henry E.; V. Lazarus, Jeffrey; Vaughan, Elly; Mendez-Sanchez, Nahum; Oliveira, Claudia P.; Gadano, Adrian; Arrese, Marco
    Non-alcoholic fatty liver disease (NAFLD) is reaching epidemic proportions worldwide. Collectively, Latin American countries have some of the highest obesity rates in the world and the fastest-growing prevalence of type 2 diabetes mellitus (T2DM). Since obesity and T2DM are intrinsically linked with NAFLD, epidemiological projections are worrisome. In addition to this adverse epidemiological setting, the region of Latin America faces unique challenges and obstacles to addressing the growing burden of NAFLD. In this article, on the occasion of the International NASH Day on June 10, 2021, we describe the main challenges and opportunities to improve care of people living with NAFLD in Latin America. Among the major challenges to be tackled are: lack of disease awareness, limited educational opportunities for healthcare personnel and general public, health system fragmentation, and lack of effective strategies for the prevention and effective treatment of NAFLD and common comorbidities, namely obesity and T2DM. Wide dissemination of current concepts on NAFLD, and extensive collaboration between scientific societies, governments, non-governmental organizations, pharmaceutical industry, and other stakeholders is urgently needed to advance the NAFLD public health policies agenda that allows us to address this disease with a whole of society approach.

    Procedural-Related Bleeding in Hospitalized Patients With Liver Disease (PROC-BLeeD): An International, Prospective, Multicenter Observational Study
    (2023) Intagliata, Nicolas M.; Rahimi, Robert S.; Higuera-de-la-Tijera, Fatima; Simonetto, Douglas A.; Farias, Alberto Queiroz; Mazo, Daniel F.; Boike, Justin R.; Stine, Jonathan G.; Serper, Marina; Pereira, Gustavo; Mattos, Angelo Z.; Marciano, Sebastian; Davis, Jessica P.

    BACKGROUND & AIMS: Hospitalized patients with cirrhosis frequently undergo multiple procedures. The risk of procedural-related bleeding remains unclear, and management is not standardized. We conducted an international, prospective, multicenter study of hospitalized patients with cirrhosis undergoing nonsurgical procedures to establish the incidence of procedural-related bleeding and to identify bleeding risk factors. METHODS: Hospitalized patients were prospectively enrolled and monitored until surgery, transplantation, death, or 28 days from admission. The study enrolled 1187 patients undergoing 3006 nonsurgical procedures from 20 centers. RESULTS: A total of 93 procedural-related bleeding events were identified. Bleeding was reported in 6.9% of patient admissions and in 3.0% of the procedures. Major bleeding was reported in 2.3% of patient admissions and in 0.9% of the procedures. Patients with bleeding were more likely to have nonalcoholic steatohepatitis (43.9% vs 30%) and higher body mass index (BMI; 31.2 vs 29.5). Patients with bleeding had a higher Model for End-Stage Liver Disease score at admission (24.5 vs 18.5). A multivariable analysis controlling for center variation found that high-risk procedures (odds ratio [OR], 4.64; 95% confidence interval [CI], 2.44-8.84), Model for End Stage Liver Disease score (OR, 2.37; 95% CI, 1.46-3.86), and higher BMI (OR, 1.40; 95% CI, 1.10-1.80) independently predicted bleeding. Preprocedure international normalized ratio, platelet level, and antithrombotic use were not predictive of bleeding. Bleeding prophylaxis was used more routinely in patients with bleeding (19.4% vs 7.4%). Patients with bleeding had a significantly higher 28-day risk of death (hazard ratio, 6.91; 95% CI, 4.22-11.31). CONCLUSIONS: Procedural-related bleeding occurs rarely in hospitalized patients with cirrhosis. Patients with elevated BMI and decompensated liver disease who undergo high-risk procedures may be at risk to bleed. Bleeding is not associated with conventional hemostasis tests, preprocedure prophylaxis, or recent antithrombotic therapy.
