background recommendations to immunize healthcare workers (hcws) against hepatitis b are well known. however, a proportion of individuals do not respond to the primary standard three-dose hb vaccination schedule. conclusions both the single- and double-dose hb vaccines were adequately immunogenic, and the double-dose hb vaccine was not significantly more immunogenic than the single-dose vaccine...
BACKGROUND/AIMS The aim of this study was to evaluate the seroconversion rate of a hepatitis A virus (HAV) vaccination in patients with hepatitis B virus (HBV)-related chronic liver disease (CLD). METHODS Analyses were conducted using clinical records from 94 patients with chronic HBV infection who were seronegative for IgG anti-HAV antibodies between September 2008 and June 2009. Two doses o...
OBJECTIVE To estimate the rate of seroconversion to positivity for hepatitis C antibody in repeat blood donors in England and to describe the probable routes of infection in these donors. DESIGN Retrospective survey of blood donors becoming positive for hepatitis C antibody and of the results of donation testing. SETTING The 14 blood centres in England. SUBJECTS All repeat donors giving b...
The aims of this study were to compare chronic hepatitis B (CHB) patients with genotypes B and C for the probability of HBeAg seroconversion, hepatitis activity, and viral replication before and after HBeAg seroconversion and to compare the prevalence of core promoter and precore mutations. A total of 180 asymptomatic Chinese patients with CHB were monitored for a median of 53.8 months, and 38 ...
BACKGROUND The identification of individuals at the highest risk of human immunodeficiency virus (HIV) infection is critical for targeting prevention strategies. We evaluated self-perceived risk of HIV infection and rates of subsequent HIV seroconversion among a prospective cohort study of injection drug users (IDUs). METHODS We performed an analysis of the time to HIV infection among 994 bas...
1. The response rate to recombinant hepatitis B vaccine was suboptimal (70.1%) in the peritoneal dialysis population. 2. We investigated whether a three-dose regimen of extrahigh dose (80 μg) of Engerix-B would achieve a higher rate of primary seroconversion and more persistent seroprotection in peritoneal dialysis patients, compared with the conventional 40-μg dose. 3. The rates of seroconvers...
The aim of this study was to determine the correlation between dynamic changes in serum cytokine/chemokine expression levels in response to entecavir (ETV) treatment and HBV e antigen (HBeAg) seroconversion in patients with chronic hepatitis B (CHB). Four cytokines (interleukin [IL]-4, IL-6, IL-8, and interferon-γ) and five chemokines (macro-phage inflammatory protein [MIP]-1α, MIP-1β, platelet...
BACKGROUND We determined the incidence of HIV seroconversion during the second and third trimesters of pregnancy and ad hoc potential cofactors associated with HIV seroconversion after having an HIV-negative result antenatally. We also studied knowledge of PMTCT among pregnant women in seven health facilities in Fako Division, South West Region, Cameroon. METHOD During the period between Sept...
BACKGROUND It is unclear whether hepatitis B e antigen (HBeAg) seroconversion induced by nucleos(t)ide analogues (NUC) has a prognosis that is similar to that of spontaneous HBeAg seroconversion. METHODS A total of 148 noncirrhotic NUC-induced HBeAg seroconverters were consecutively enrolled. A historical control of 407 noncirrhotic spontaneous HBeAg seroconverters was also recruited. We comp...
