Background: The hepatitis C pandemic has been systematically studied and characterized in North America and Europe, but this important public health problem has not received equivalent attention in other regions. Aim: The objective of this systematic review was to characterize hepatitis C virus (HCV) epidemiology in selected countries of Asia, Australia and Egypt, i.e. in a geographical area inhabited by over 40% of the global population. Methodology: Data references were identified through indexed journals and non‐indexed sources. In this work, 7770 articles were reviewed and 690 were selected based on their relevance. Results: We estimated that 49.3–64.0 million adults in Asia, Australia and Egypt are anti‐HCV positive. China alone has more HCV infections than all of Europe or the Americas. While most countries had prevalence rates from 1 to 2% we documented several with relatively high prevalence rates, including Egypt (15%), Pakistan (4.7%) and Taiwan (4.4%). Nosocomial infection, blood transfusion (before screening) and injection drug use were identified as common risk factors in the region. Genotype 1 was common in Australia, China, Taiwan and other countries in North Asia, while genotype 6 was found in Vietnam and other Southeast Asian countries. In India and Pakistan genotype 3 was predominant, while genotype 4 was found in Middle Eastern countries such as Egypt, Saudi Arabia and Syria. Conclusion: We recommend implementation of surveillance systems to guide effective public health policy that may lead to the eventual curtailment of the spread of this pandemic infection.

Bone marrow MSCs transplantation either undifferentiated or differentiated can be used as a potential treatment for liver cirrhosis.

Liver fibrosis is a common pathway leading to cirrhosis, which is the final result of injury to the liver.

Background Dendritic cells (DCs) could be used as potential cellular adjuvant for the production of specific tumor vaccines. Objectives Our study was aimed to evaluate the safety and efficacy of autologous pulsed DC vaccine in advanced hepatocellular carcinoma (HCC) patients in comparison with supportive treatment. Methods Thirty patients with advanced HCC not suitable for radical or loco-regional therapies were enrolled. Patients were divided into 2 groups, group I consisted of 15 patients received I.D vaccination with mature autologous DCs pulsed ex vivo with a liver tumor cell line lysate. Group II (control group, no. 15) received supportive treatment. One hundred and 4 ml of venous blood were obtained from each patient to generate DCs. DCs were identified by CD80, CD83, CD86 and HLA-DR expressions using flow cytometry. Follow up at 3, and 6 months post injection by clinical, radiological and laboratory assessment was done. Results Improvement in overall survival was observed. Partial radiological response was obtained in 2 patients (13.3 %), stable course in 9 patients (60 %) and 4 patients (26.7 %) showed progressive disease (died at 4 months post-injection). Both CD8+ T cells and serum interferon gamma were elevated after DCs injection. Conclusion Autologous DC vaccination in advanced HCC patients is safe and well tolerate.
