Early declines in serum hepatitis B surface (HBsAg) levels, their optimal cutoffs, and association with therapeutic endpoints in chronic hepatitis B (CHB) patients receiving entecavir treatment remain unclear. We prospectively enrolled 529 patients (195 hepatitis B e antigen [HBeAg]-positive and 334 HBeAg-negative) with a median treatment duration of 49.2 months. Median HBsAg levels declined significantly in both groups at Month 3, but only at Months 6-12 in the HBeAg-negative group. Both groups exhibited a significant HBsAg decline with each successive year of treatment...

BACKGROUND: In kidney transplant recipients (KTRs) with hepatitis B virus (HBV) infection, immunosuppression may increase viral replication with increased risk for liver disease progression and HBV-related kidney diseases, factors that could adversely influence graft and patient outcomes. We aimed to analyze the impact of different phases of HBV infection on the outcomes in KTRs. METHODS: Using the Organ Procurement and Transplant Network/United Network for Organ Sharing database, we selected adult KTRs from 2001 to 2011 who received peri-operative antibody induction followed by calcineurin inhibitor/mycophenolate mofetil maintenance with/without steroid...

BACKGROUND: Chronic hepatitis B virus (HBV) infection is associated with a weak but specific cellular immune response of the host to HBV. Tripeptidyl peptidaseⅡ (TPPⅡ), an intracellular macromolecule and proteolytic enzyme, plays an important complementary and compensatory role for the proteasome during viral protein degradation and major histocompatibility complex class I antigen presentation by inducing a specific cellular immune response in vivo. Based on a previous study, we aimed to explore the role of MHC class I antigen presentation in vivo and the mechanisms that may be involved...

Chronic hepatitis B infection (CHB) causes up to 1.0 million deaths annually. Currently, more than 90% of CHB patients worldwide are receiving indefinite nucleos(t)ide analogue (NA) therapy. New strategies for optimizing hepatitis B surface antigen (HBsAg) loss are required for NA-treated patients as the majority are unable to achieve HBsAg loss and may require lifelong therapy. In hepatitis B e antigen (HBeAg)-positive patients, switching from NAs to finite peginterferon (PegIFN) therapy can double HBeAg seroconversion rates...

The majority of patients with acute febrile jaundice (>95%) identified through a yellow fever surveillance program in the Democratic Republic of Congo (DRC) test negative for antibodies against yellow fever virus. However, no etiological investigation has ever been carried out on these patients. Here, we tested for hepatitis A (HAV), B (HBV), C (HCV), D (HDV) and E (HEV) viruses, all of which can cause acute febrile jaundice, in patients included in the yellow fever surveillance program in the DRC. On a total of 498 serum samples collected from suspected cases of yellow fever from January 2003 to January 2012, ELISA techniques were used to screen for antibodies against HAV (IgM) and HEV (IgM) and for antigens and antibodies against HBV (HBsAg and anti-HBc IgM), HCV and HDV...

Hepatitis B surface antigen (HBsAg) reduction during nucleoside/nucleotide analog (NA) therapy is slow and an alternative strategy for patients receiving ongoing NA to facilitate HBsAg reduction is required. We investigated whether switching to pegylated interferon (PEG-IFN) after long-term NA administration enhances HBsAg reduction. Forty-nine patients who switched from long-term NA to 48 weeks of PEG-IFN alfa-2a were studied. The mean duration of previous NA was 48 months (sequential group). A total of 147 patients who continued NA and matched for baseline characteristics were analyzed for comparison (NA continuation group)...

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...

Co-infection of schistosomiasis, HBV and HCV is common in countries where schistosomiasis is endemic. Occult hepatitis B occurs in patients at high risk for HBV infection (e.g., patients on hemodialysis, patients receiving blood transfusions). Schistosomal infection is a risk factor of HBV infection that can increase the incidence of occult hepatitis B. We aimed to determine the prevalence of occult hepatitis B in chronic hepatitis C patients with and without schistosomiasis and to assess the effect of schistosomal infection on the increased risk of exposure to HBV infection and to occult hepatitis B...
