OBJECTIVE: To evaluate early and long term anamnestic response to a booster dose of HBV vaccine among non-seroprotected children. SUBJECTS AND METHOD: A national community based project was carried out on 3600 children aged 9 months to 16 years, fully vaccinated during infancy. They were recruited from 6 governorates representing Egypt. It revealed that 1535 children (42.8%) had non sero-protective anti-HBs (<10 IU/L) and were HBsAg or anti-HBc negative. A challenging dose of 10 μg of mono-valent Euvax HBV vaccine was given to 1121/1535 children...

Chronic Hepatitis B Virus (HBV) infection is linked to hepatocellular carcinoma (HCC) pathogenesis. Despite the availability of a HBV vaccine, current treatments for HCC are inadequate. Globally, 257 million people are chronic HBV carriers, and children born from HBV-infected mothers become chronic carriers, destined to develop liver cancer. Thus, new therapeutic approaches are needed to target essential pathways involved in HCC pathogenesis. Accumulating evidence supports existence of hepatic cancer stem cells (hCSCs), which contribute to chemotherapy resistance and cancer recurrence after treatment or surgery...

Telbivudine is an orally nucleoside analog with potent and specific antihepatitis B virus (HBV) activity, and it has been reported to block mother-to-infant transmission. However, few studies have focused on the safety of prenatal exposure for offspring development.This is a prospective noninterventional study. Participants were enrolled during delivery through the Women's Hospital of Zhejiang University School of Medicine between January 2012 and September 2013. Neonate's umbilical cord arterial blood (UCAB) was collected after delivery...

AIMS: Anti-CD20 antibodies are increasingly being used to treat idiopathic nephrotic syndrome (INS) in children. While they may allow steroid and calcineurin-inhibitor withdrawal, repeated infusions of anti-CD20 antibodies are often required to maintain remission. Data on their potential toxicity in INS are needed to consider repeated infusions. METHODS: We reported data on side effects related to the use of rituximab (a chimeric anti-body; 130 pts) and ofatumumab (a humanized anti-body; 37 pts) in children with INS (steroid-dependent and steroid/calcineurin-inhibitor dependent disease) treated in a national referral center during a 9-year period (400 treatments; follow-up 1-9 years)...

The aim of this study was to assess the immune response to HBV vaccine in HIV-exposed infants and to correlate it to HBV infection acquisition. Protective anti-HBs levels (> 10 mIU/ml) were found in 54/58 (93.2%) infants at 6 months, 126/144 (87.5%) at 12 months and 141/176 (80.1%) children at 24 months. HBV infection (7 children were HBsAg+ at Month 24) occurred also in the presence of levels above 10 mIU/ml. Our findings indicate limited impact of HIV exposure on anti-HBV immune response, but suggest that levels > 10 mIU/ml may be required to confer protection in this context...

Human enterovirus 71 (EV71) is the second most common cause of hand, foot, and mouth disease (HFMD), which can occur as a severe epidemic especially among children under 5-years old. New and improved treatment strategies to control EV71 infection are therefore urgently required. The heterocyclic compound GS-9620, a potent and selective agonist of Toll-like receptor 7 (TLR7), has been reported to activate plasmacytoid dendritic cells (pDCs), and suppress HBV as well as HIV replication. In this study, we indicated that GS-9620 also could inhibit EV71 replication in the mouse model of EV71 infection...

Many U.S.-bound refugees originate from countries with intermediate or high hepatitis B virus (HBV) infection prevalence and have risk for severe liver disease. We evaluated HBV screening and vaccination of newly arrived refugees in four states to identify program improvement opportunities. Data on HBV testing at domestic health assessments (1/1/2009-12/31/2011) were abstracted from state refugee health surveillance systems. Logistic regression identified correlates of infection. Over 95% of adults aged ≥19 years (N = 24,647) and 50% of children (N = 12,249) were tested...

The children immunisation programme in Greenland correlates to the one in Denmark with the addition of the Bacille Calmette-Guerin (BCG)-vaccine and the immunisation against Hepatitis B (HBV). The immunisation rate among children in Greenland has been and is currently unknown and this study aims to estimate the immunisation rates among children in Nuuk from 1 July 2015 until 30 June 2016. We did an observational cross-sectional study based on a statistical extraction identifying all children in Nuuk eligible for an immunization in the children immunisation programme from 1 July 2015 until 30 June 2016 and a review of their medical records...

Hepatitis B virus (HBV) is a significant public health issue that has not been adequately addressed, especially in the high-prevalence region of Africa. Despite the incorporation of HBV vaccines into the Expanded Program on Immunization (EPI), children continue to be infected with HBV through maternal-to-child transmission (MTCT). The addition of a birth dose of HBV vaccine would be a cost-effective method to reduce MTCT. Birth-dose HBV vaccine policies have been adopted in the Western Pacific region but have yet to be implemented in the African region...
