Eosinophilic Granulomatosis with Polyangiitis (EGPA) or Churg-Strauss syndrome is a rare systemic illness which is characterized by necrotizing inflammation of small and medium sized vessels. The prominent features include asthma, eosinophilia, transient pulmonary infiltration and systemic vasculitis. Various triggering factors have been reported as putative aetiological agents of Churg-Strauss syndrome. They include infections, allergic desensitization, vaccinations like hepatitis B and influenza vaccination, cocaine abuse, drugs like leukotriene receptor antagonists and exposure to pigeons...

Approximately 240 million people have chronic hepatitis B worldwide, with mother-to-child-transmission (MTCT) accounting for most cases. Therefore, Henan Province, China launched a public health program to prevent MTCT. To determine the efficacy of this health program, a survey was carried out in Huixian and Xinan counties, which are located in northern and western Henan. All infants born in these two counties between January 1, 2013 and March 31, 2014 to a mother positive for hepatitis B surface antigen (HBsAg), were surveyed; in total, there were 438 mother-infant pairs...

The mechanism for the coexistence of hepatitis B surface antigen (HBsAg) and antibodies to HBsAg (anti-HBs) in chronic HBV infected patients remains controversial. This study aimed to explore the role of HBV S gene mutation and anti-HBs subtype-nonspecificity in patients with simultaneous HBsAg/anti-HBs positivity. Chronic HBV infections with (n = 145, group I) and without (n = 141, group II) anti-HBs were included. The S gene was amplified and sequenced. The neutralization experiment was used in group I patients' sera to determine the specificity of anti-HBs...

BACKGROUND: In universal hepatitis B (HB) vaccination, single vaccine-derived polyclonal anti-HBs antibodies (anti-HBs) need to inhibit infection of HB viruses (HBV) of non-vaccine genotypes. We experimentally addressed this issue. METHODS: Anti-HBs-positive sera were obtained by vaccination with genotype A- or C-derived HBs antigen (HBsAg, gtA-sera or gtC-sera). Their reactivity to genotype A- and C-derived HBsAg (gtA-Ag and gtC-Ag) was measured by ELISA. The capacity of sera to neutralize HBV was evaluated using an in vitro infection model...

BACKGROUND: Hepatitis is a viral infection of the liver. It is mainly transmitted between people through contact with infected blood, frequently from mother to baby in-utero. Hepatitis B poses significant risk to the fetus and up to 85% of infants infected by their mothers at birth develop chronic hepatitis B virus (HBV) infection. Hepatitis B immunoglobulin (HBIG) is a purified solution of human immunoglobulin that could be administered to the mother, newborn, or both. HBIG offers protection against HBV infection when administered to pregnant women who test positive for hepatitis B envelope antigen (HBeAg) or hepatitis B surface antigen (HBsAg), or both...

We investigated breakthrough infection and hepatitis B virus (HBV) genetic changes in immunized subjects after 25-year of a universal infant immunization. Specifically, serum HBV DNA, genotypes, surface antigen mutants and nucleoside analog-resistant (NAr) mutants were assessed in 2853 subjects (<25-years-old) surveyed in 2009, and these data were compared with the data from previous serosurveys. A comparison across different age-stratified groups using the 2009 data revealed a significant increase in the seropositive rate of anti-HBc (5...

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...

: Patients with resolved hepatitis B virus (HBV) infection who are treated for hematological malignancies remain at risk for HBV reactivation. Because of conflicting studies about whether the antibody to hepatitis B surface antigen (anti-HBs) protects against reactivation in patients with resolved infection (hepatitis B surface antigen negative) receiving chemotherapy for hematological malignancies, we conducted a meta-analysis to determine if anti-HBs reduces HBV reactivation risk. We sought English language studies through March 1, 2016 in Medline and other sources that examined reactivation in patients with resolved HBV infection receiving chemotherapy for hematologic malignancies...

Hepatitis B virus (HBV) causes different clinical manifestations, ranging from asymptomatic carriage to fulminant or chronic hepatitis. Serological tests are widely used for the diagnosis of HBV infections to detect viral markers. However, facing with atypical serological profiles in some patients leads to problems in interpreting of the results and management of the patients. The aims of this study were to investigate the atypical serologic profiles seen in patients screened for HBV infection and the S gene mutations in patients with concurrent positivity of HBsAg and anti-HBs...

Hepatitis B virus (HBV) is a member of Hepadnavirus family, which leads to chronic infection in around 5% of patients with a high risk of developing liver cirrhosis, liver failure, and hepatocellular carcinoma. (1) Despite the availability of prophylactic vaccines against hepatitis B for over three decades, there are still more than two billion people have been infected and 240 million of them were chronic. Antiviral therapies currently used in the treatment of CHB (chronic hepatitis B) infection include peg-interferon, standard α-interferon and nucleos/tide analogues (NAs), but none of them can provide sustained control of viral replication...

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...
