Serum levels of anti-hepatitis B surface antibodies among vaccinated children aged 1 to 12 years in a rural community in Fars Province, southern Iran. J Immunoassay Immunochem. 2019 Oct 07;:1-8 Authors: Arefkhah N, Vafazadeh S, Shahriarirad S, Ghorbani F, Zoghi S, Emami M, Zamiri B, Cheraghi MR, Sarvari J, Sarkari B Abstract The present study aimed to find out the levels of anti-HBsAb among vaccinated children in a rural community in Fars Province, Southern Iran. Blood samples were taken from 550 children, aged 1-12 years (mean 6.4 ± 3.5), in 2017 from three villages in the area. A structured questionnaire was used to get the sociodemographic data of the subjects along with determinants concerning the Hepatitis B. Sera samples were examined for anti-HBsAb, using an ELISA commercial kit. Anti-HBsAb were detected in 468 (85.1%) of the subjects. Of the seropositive subjects, 37 (45.1%) were female and 45 (54.9%) were male. In the age group of 0-5 years, 88.7% of the subjects were seropositive. This rate was 84.3% and 78.1% in the age group of 6-10 years old and older than 10 years, respectively. There was a significant association (p

This study aims to analyze the prevalence and to concentrate on the key risk factors that are responsible for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infection in patients on HD visiting two dialysis centers in the city of Quetta in southwestern Pakistan. The overall incidence of HBV was found to be 16.1%, the overall incidence of HCV was found to be 43.2%, and two patients (1.6%) were found to be positive for both HBV and HCV. HIV was not found among patients seen at both hospitals during the study period. The main risk factors for development of a viral infection were the ...

Abstract Hexavalent vaccines containing diphtheria, tetanus, pertussis, Haemophilus influenzae type b, poliomyelitis, and hepatitis B virus antigens have the potential to be used for the primary series in India (6, 10, 14 weeks of age) and the toddler booster dose. Three hexavalent vaccines are available in India: DTwP-Hib/HepB-IPV (wP-hexa), DTaP-IPV-HB-PRP~T(2aP-hexa), and DTaP-HBV-IPV/Hib (3aP-hexa). In the three published phase-3 Indian studies, pertussis 'vaccine response' rates 1 month after a 6-10-14-week primary series were 68.4-75.7% for wP-hexa, 93.8-99.3% for 2aP-hexa, and 97.0-100% for 3aP-hexa; seropr...

Abstract Hepatitis B virus (HBV) affects an estimated 250 million chronic carriers worldwide. Though several vaccines exist, they are ineffective for those already infected. HBV persists due to the formation of covalently-closed circular DNA (cccDNA) - the viral minichromosome - in the nucleus of hepatocytes. Current nucleoside analogs and interferon therapies rarely clear cccDNA, requiring lifelong treatment. Our group identified GLP-26, a novel glyoxamide derivative that alters HBV nucleocapsid assembly and prevents viral DNA replication. GLP-26 exhibited single-digit nanomolar anti-HBV activity and inhibition o...

CONCLUSIONS: Despite the highly effectiveness of the standard hepatitis B vaccination regimen at 6 months after completion, the long-term immunogenicity was lower than the four double doses regimen among HIV-infected adults with CD4+ cell counts > 200 cells/mm3 and undetectable plasma HIV-1 RNA. The standard vaccination regimen may not be the best strategy to provide long-term immune response against hepatitis B virus among HIV-infected individuals.

Abstract BACKGROUND: We performed a systematic review and meta-analysis to examine factors associated with HBV immune response in dialysis patients, and the association between the immune response to the HBV vaccine and mortality. METHODS: Electronic databases were searched for studies of dialysis patients that compared the characteristics of HBV vaccine responders and non-responders. Mortality was also analyzed according to the vaccine immune response (defined by hepatitis B surface antibody titer > 10 mIU/mL). Random-effects model meta-analyses were performed to compute a weighted mean...
