Article Synopsis
  • Direct-acting antivirals have led to a rise in hepatocellular carcinoma (HCC) cases in patients who have achieved sustained virologic response (SVR) for hepatitis C, with limited understanding of regional differences in outcomes post-SVR HCC.
  • A study of 8796 patients with advanced liver fibrosis found that 6.6% developed HCC, revealing significant geographic variations in detection, tumor size, and survival rates, with East Asia, North America, and South America having the best outcomes.
  • The findings suggest that implementing HCC surveillance can lead to earlier detection and improved survival rates, highlighting its importance as an intervention strategy across different regions.

Hepatitis D virus (HDV) infection occurs as a coinfection with hepatitis B and increases the risk of hepatocellular carcinoma, decompensated cirrhosis, and mortality compared to hepatitis B virus (HBV) monoinfection. Reliable estimates of the prevalence of HDV infection and disease burden are essential to formulate strategies to find coinfected individuals more effectively and efficiently. The global prevalence of HBV infections was estimated to be 262,240,000 in 2021.

To achieve WHO's goal of eliminating hepatitis C virus (HCV), innovative strategies must be designed to diagnose and treat more patients. Therefore, we aimed to describe an implementation strategy to identify patients with HCV who were lost to follow-up (LTFU) and offer them re-linkage to HCV care. We conducted an implementation study utilizing a strategy to contact patients with HCV who were not under regular follow-up in 13 countries from Latin America.

Chronic liver disease is an important cause of morbidity and mortality among people living with human immunodeficiency virus (HIV) and is frequently related to non-alcoholic fatty liver disease (NAFLD). The objective is to estimate the prevalence and risk factors of hepatic steatosis among consecutive patients with stable HIV infection on antiretroviral therapy (ART). Also, the use of transient elastography (TE) as a mean to identify a subgroup at risk for non-alcoholic steatohepatitis (NASH) and/or liver fibrosis.
