Cell death markers, M65 and M30, have been suggested to be sensitive markers of liver inflammation and fibrosis in nonalcoholic fatty liver disease and chronic hepatitis C. Our aim was to investigate whether these markers were useful in diagnosing liver inflammation and fibrosis in chronic hepatitis B (CHB).We examined 186 patients with CHB; 18 sex- and age-matched healthy subjects were controls. The blood samples were collected from CHB patients within 1 week before or after liver biopsy. According to METAVIR score system, liver inflammation was graded from A0 to A3, and fibrosis from F0 to F4...

Recently, concerns were raised of high rates of HCC recurrence in patients treated with direct acting antivirals (DAA) for hepatitis C infection. We investigated the HCC occurrence and recurrence rates within six months after treatment with DAA with or without Pegylated Interferon (PEG-IFN) in real life. This is a retrospective, multicenter cohort trial, executed in 15 hospitals distributed across Belgium. Populations were matched based on fibrosis score (Metavir F3-F4). Patients with a Child-Pugh score ≥ B were excluded...

BACKGROUND AND AIM: In Asia-Pacific where cost is a major concern, peginterferon plus ribavirin (PR) often remain as the standard of care in chronic hepatitis C (CHC) treatment, while the direct-acting antivirals (DAAs) are commonly recommended as retreatment. Newer DAAs can achieve a sustained virological response (SVR) of nearly 100% with pan-genotypic coverage, that is "Highly Effective DAAs." We aimed to investigate the most desirable cost range for the Highly Effective DAAs using Hong Kong as an example...

Acute hepatitis C virus infection remains a major health concern in human immunodeficiency virus(HIV)-infected men who have sex with men (MSM). New direct-acting antiviral agent (DAA) combination therapy has not yet been approved for the treatment for acute hepatitis C virus(HCV), thereby potentially causing deferral of HCV treatment. Therefore, we aimed to study the course of liver disease after an episode of acute HCV. This study is a retrospective single-centre cohort of HIV-positive MSM with acute HCV infection...
