Although a universal newborn hepatitis B (HB) immunization program has been implemented in China, hepatitis B virus (HBV) breakthrough infection, including HB surface antigen (HBsAg)-positive infection and occult HBV infection (OBI), still occurs during infancy or childhood. Obtaining the actual prevalence of HBV infection in general children is important for preventing and controlling the spread of HB. Accordingly, we investigated the prevalence of overt infection and OBI in community children and compared the serological and virological characteristics of OBI and HBsAg-carrier children to clarify the mechanisms related to OBI...

OBJECTIVES: Patients with inflammatory bowel disease (IBD) often receive immunosuppressive therapy which may make them vulnerable to infections such as hepatitis B. We hypothesized that hepatitis B virus (HBV) titers are low in the vaccinated pediatric IBD population. The aims of our study were to identify the incidence of lower titers of hepatitis B surface antibody (HBsAb) and determine which patient factors may be associated with lower HBsAb titers. METHODS: Patients with diagnosis of IBD, ages 5-18 years, were prospectively enrolled...

We determined the anti-HBs titer in 227 children of all ages with Down syndrome (DS). Only 48.1% (95% CI: 35.1-61.3) of the DS children aged 7-10 years and 31.9% (95% CI: 22.1-43.6) of the DS children aged >10 years had a protective anti-HBs titer (≥10 IU/l). The geometric mean anti-HBs titer was significantly lower in the DS children; this suggests booster vaccination for HBV may be needed. This article is protected by copyright. All rights reserved.

PURPOSE OF REVIEW: Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections and HIV-HBV and HCV coinfection are major causes of chronic liver disease worldwide. Testing and diagnosis is the gateway for access to both treatment and prevention services, but there remains a large burden of undiagnosed infection globally. We review the global epidemiology, key challenges in the current hepatitis testing response, new tools to support the hepatitis global response (2016-2020 Global Hepatitis Health Sector strategy, and 2017 WHO guidelines on hepatitis testing and their key recommendations) and future directions and innovations in hepatitis diagnostics...

Regular blood transfusion therapy remains the primary treatment in thalassemia major (TM). Transfusion-transmitted infections (TTIs) and iron overload are considered to be the major drawbacks of this therapy. This cross-sectional study aimed to update the prevalence of the hepatitis C virus (HCV) antibody, PCR-confirmed HCV, hepatitis B surface antigen (HBsAg), and human immunodeficiency virus (HIV) antibody among TM children. Clinical and epidemiological factors that can affect HCV infection prevalence rate were studied...

In France, hepatitis B (HB) vaccine has been offered to all infants since 1994, and was proposed to all children aged 11 years from 1994 to 1998. Nevertheless, HB vaccine hesitancy may result in low vaccination coverage in present-day at-risk adults. We aimed to determine HB vaccination coverage in adults attending a free testing center for sexually transmitted infections (STI). As part of routine care, three classes of data were anonymously collected from attendees over a 3-month period: results of HB serologic tests; date and number of past anti-hepatitis B virus (HBV) immunization(s) (if any) according to health records; and the risk of STI and blood-transmitted infections (BTI)...

Although the introduction of hepatitis B vaccine has been contributing to the reduction in the prevalence of hepatitis B virus (HBV) carriers worldwide, the treatment of children with chronic HBV infection is a challenge to be addressed. HBeAg seroconversion, which induces low replication of HBV, is widely accepted as the first goal of antiviral treatment in children with chronic hepatitis B. However, spontaneous HBeAg seroconversion is highly expected in children with chronic HBV infection. Therefore, the identification of children who need antiviral treatment to induce HBeAg seroconversion is essential in the management of chronic HBV infection...

INTRODUCTION: Hepatitis B virus (HBV) vaccination programs generally target infants to prevent chronic HBV infection and/or pre-adolescents to reduce transmission in adulthood. To assess whether infant HBV immunization can potentially accomplish both objectives we measured residual immunity 10-16 years after vaccination in Canadian children. METHODS: A prospective, parallel group, single center study enrolled adolescents given HBV vaccine at 2, 4, and 6 months of age...

BACKGROUND: Sub-Saharan Africa is undergoing an epidemiological transition from a predominance of infectious diseases to non-communicable and lifestyle related conditions. However, the pace of this transition and the pattern of disease epidemiology are uneven between affluent urban and rural poor populations. To address this question for a remote rural region located in the central African rainforest region of Gabon, this study was conducted to assess reasons for health care attendance and to characterize the epidemiology of malaria and other major infectious diseases for the department of Tsamba Magotsi...

The US-affiliated Pacific Island countries (USAPI) is an endemic region for hepatitis B virus (HBV) infection. Universal infant hepatitis B vaccination was introduced in the USAPI in the mid-1980s to mitigate the HBV burden. We assessed the impact of universal infant vaccination on the HBV infection prevalence over time among children born in the 1980s, 1990s, and 2000s in the USAPI. Demographic and serologic data from serial sero-surveys conducted between 1985 and 2015 were obtained. Descriptive statistics and analysis of variance were performed...

Background and aims Childhood vaccinations are an important component of primary prevention. Maternal and Child Health (MCH) clinics in Israel provide routine vaccinations without charge. Several vaccine-preventable-diseases outbreaks (measles, mumps) emerged in Jerusalem in the past decade. We aimed to study attitudes and knowledge on vaccinations among mothers, in communities with low immunization coverage. Methods A qualitative study including focus groups and semi-structured interviews. Results Low immunization coverage was defined below the district's mean (age 2 years, 2013) for measles-mumps-rubella-varicella 1st dose (MMR1\MMRV1) and diphtheria-tetanus-pertussis 4th dose (DTaP4), 96 and 89%, respectively...

Chronic hepatitis B virus (HBV) infection leads to a risk of developing cirrhosis and hepatocellular carcinoma. In France, where the prevalence of HBV is low, mother-to-child transmission is the cause of chronic infection in more than one-third of cases. After exposure, the risk of chronic infection is the highest for newborns (90 %). The World Health Organization implemented a global immunization program in 1991, applied in France in 1994. A significant number of children are infected each year, however, and failure of postexposure prophylaxis is reported in 4-10 % of newborns...

The prevalence of hepatitis B virus (HBV) in Wallis and Futuna (WAF) was one of the highest in the Pacific and was the driving factor for introducing hepatitis B (HepB) vaccination in 1992 and HepB birth dose (HepB-BD) in 2006. Using transmission assessment survey (TAS) as a survey platform for eliminating lymphatic filariasis (LF), we assessed HBV surface antigen (HBsAg) seroprevalence, HepB vaccination coverage, and its timeliness among schoolchildren in WAF. From one finger prick of all registered fourth and fifth grade students, we tested HBsAg and filariasis antigen simultaneously, and estimated HepB vaccination coverage and timeliness by reviewing students' immunization cards...
