Introduction: Although the effectiveness of direct-acting antivirals (DAAs) for the treatment of chronic hepatitis C virus (HCV) has been reported in real-world settings, predictive factors of treatment failure are lacking. Therefore, we sought to explore the baseline predictors of treatment response to DAAs.

Methods: This was a prospective multicenter cohort study from the Latin American Liver Research Educational and Awareness Network (LALREAN) including patients who received DAA treatment from May 2016 to April 2019.

Introduction & Objectives: Liver cirrhosis is a major cause of mortality worldwide. Adequate diagnosis and treatment of decompensating events requires of both medical skills and updated technical resources. The objectives of this study were to search the demographic profile of hospitalized cirrhotic patients in a group of Latin American hospitals and the availability of expertise/facilities for the diagnosis and therapy of decompensation episodes.

Background & Aims: Little is known about how a sustained virologic response (SVR) to treatment of hepatitis C virus infection with direct-acting antivirals (DAAs) affects patient mortality and development of new liver-related events. We aimed to evaluate the incidence of disease progression in patients treated with DAAs.

Methods: We performed a prospective multicenter cohort study of 1760 patients who received DAA treatment at 23 hospitals in Latin America, from May 1, 2016, through November 21, 2019.

The ECHO model was developed to expand access to medical care for populations with HCV infection in underserved areas. We aimed to compare HCV treatment outcomes in community-based clinics with the Austral University Hospital (AUH) and to assess improvement in physician knowledge and skills. In October 2015, we established an HCV ECHO clinic at the AUH in Buenos Aires.

Background & Aims: Data from Europe and North America have been published regarding the risk of developing hepatocellular carcinoma (HCC) after treatment with direct antiviral agents (DAA). We proposed to evaluate cumulative incidence and associated risk factors for de novo HCC.

Methods: This was a prospective multicentre cohort study from Latin America including 1400 F1-F4-treated patients with DAAs (F3-F4 n = 1017).

Article Synopsis
  • - The study examined liver disease prevalence in Lara, a rural community in Argentina, known for high rates of Hepatitis A Virus (HAV) infection among children and lacking basic amenities like electricity and clean water.
  • - A total of 102 residents participated, revealing that while HAV infection rates were high among adults (89%), children had significantly lower exposure (35%), especially those under 5 years old.
  • - Findings showed that adults had mild liver issues like steatosis and gallstones, with no evidence of Hepatitis B or C infections, but the serological tests for other conditions like echinococcal disease suggested high false-positive rates.
