Hepatitis C virus (HCV) quasispeciation was studied in two children vertically coinfected with HCV and human immunodeficiency virus type 1 (HIV-1). HCV quasispecies diversification and liver injury were more significant in patient C1, who was immunocompetent with anti-HIV therapy, than in patient C2, who was immunosuppressed, in consistency with modulation of HCV quasispeciation and liver injury by immunocompetence in coinfected children.

In this editorial, we comment on the article by Mu , published in the recent issue of the . We pay special attention to the immune tolerance mechanism caused by hepatitis B virus (HBV) infection, the pathogenesis of hepatocellular carcinoma (HCC), and the role of antiviral therapy in treating HCC related to HBV infection. HBV infection leads to systemic innate immune tolerance by directly inhibiting pattern recognition receptor recognition and antiviral signaling pathways, as well as by inhibiting the immune functions of macrophages, natural killer cells and dendritic cells.

Minimal change disease (MCD) accounts for 10 - 15% of idiopathic nephrotic syndromes in adults. Chronic hepatitis C virus (HCV) infection is rarely ascribed as a cause of MCD and was previously associated with interferon-based therapy. MCD in treatment-naïve chronic HCV infection is extremely rare, with only 3 cases reported in the literature.

Chronic hepatitis C virus (HCV) infection is associated with significant morbidity, mortality and health economic burden. Over 90% of HCV cases in England occur in people who inject drugs (PWID). Current treatments for HCV are effective but do not protect against reinfection.

As the second most populated country in Africa, Ethiopia needs public health measures to control diseases that impact its population. The goal of this study is to analyse disease burdens of HBV and HCV, while also highlighting their estimated associated costs for the country. A literature review and a Delphi process reflecting input of Ethiopian experts and the National Viral Hepatitis Technical Working Group were used to complement mathematical modelling to estimate HBV and HCV disease and economic burdens.
