Summary The disease burden of hepatitis C virus ( HCV ) is expected to increase as the infected population ages. A modelling approach was used estimate total number viremic infections, diagnosed, treated and new infections in 2013. In addition, model change progression mortality 2013–2030. Finally, expert panel consensus capture current treatment practices each country. Using today's paradigm, projected decline or remain flat all countries studied. However, same time period, individuals with...

Summary The number of hepatitis C virus ( HCV ) infections is projected to decline while those with advanced liver disease will increase. A modeling approach was used forecast two treatment scenarios: (i) the impact increased efficacy keeping treated patients constant and (ii) increasing rate. This analysis suggests that successful diagnosis a small proportion can contribute significantly reduction burden in countries studied. largest ‐related morbidity mortality occurs when combined higher...

Fatty liver disease associated with metabolic dysfunction has emerged as a significant global health challenge. This condition often coexists other diseases, such alcohol-related and viral hepatitis, complicating both diagnosis management. To address the limitations of non-alcoholic fatty (NAFLD) classification, two alternative frameworks have been proposed: dysfunction-associated (MAFLD) in 2020 steatotic (MASLD) 2023. A key difference between these definitions is how they consider relation...

Hepatitis B e antigen (HBeAg)-negative chronic hepatitis patients are at high risk of treatment relapse after any antiviral therapy. Combining peginterferon alpha-2a with ribavirin might improve sustained response rates.Overall, 138 HBeAg-negative were randomized to receive monotherapy (peginterferon 180 microg weekly plus placebo) or combination therapy 1,000 1,200 mg daily, depending on body weight) for 48 weeks.

Abstract The 69th World Health Assembly endorsed the Global Sector Strategy for Viral Hepatitis, embracing a goal to eliminate hepatitis infection as public health threat by 2030. This was followed Organization's (WHO) global targets care and management of B virus (HBV) C (HCV) infections. These announcements were important in raising awareness calling action; however, tracking countries’ progress towards these elimination goals has provided insights limitations targets. existing compare...

Background: We recently developed a simple novel index called fibrosis 6 (FIB-6) using machine learning data analysis. aimed to evaluate its performance in the diagnosis of liver and cirrhosis chronic hepatitis B (CHB). Methods: A retrospective observational analysis was obtained from seven countries (Egypt, Kingdom Saudi Arabia (KSA), Turkey, Greece, Oman, Qatar, Jordan) CHB patients. The inclusion criteria were receiving an adequate biopsy complete biochemical hematological data....

Hepatic epithelioid hemangioendothelioma (HEH) is a rare vascular tumor of the liver unknown etiology. Although HEH usually characterized by low grade malignancy and good long-term prognosis, its growth can be progressive lead to hepatic failure, extrahepatic metastasis death. Several different antineoplastic agents have been proposed for cases nonresectable HEH. We report case 45-year-old man with successfully treated intravenous infusion Adriamycin.
