Active clinical trials for "Hepatitis B"

Vertical HIV transmission has been dramatically reduced by the use of combined antiretroviral therapy in HIV-infected pregnant women. Among the most often used drugs, several have dual activity, against HIV and HBV: lamivudine, emtricitabine, tenofovir. Studies about vertical HBV transmission from HIV-HBV co-infected pregnant women are rare in developed countries. The study hypothesis is a major reduction of the risk of HBV vertical transmission.

The aim of our prospective study is to construct and validate a non-invasive model consisting biochemical markers, FibroScan, and radiological parameters for evaluating liver fibrosis caused by hepatitis B virus in mainland China.

The aim of our study is to evaluate liver fibrosis using biochemical markers, FibroScan, and radiology methods in patients with chronic hepatitis B in mainland China.

This retrospective study will evaluate the association of biomarkers and the treatment response of patients with chronic hepatitis B, who have completed therapy with Pegasys (peginterferon alfa-2a) ± lamivudine. For the analysis stored serum samples obtained from patients will be used; no actual patients are involved.

The purpose of this study is to support the clinical value of entecavir by assessing the relationship between viral load and histological improvement.

The purpose of this study is to evaluate the risk of hepatitis B reactivation in patients undergoing allografting.

To determine whether HBeAg-positive and HBeAg-negative patients with HBV DNA greater than or less than 5 log10 and 4 log10 copies/mL, respectively, and with normal or minimally elevated liver transaminases have histological evidence of active liver disease.

The primary objective of this study is to evaluate hepatitis B surface antigen (HBsAg) loss in subjects who stop nucles(t)ide analogues (NAs) (Stop arm) compared to subjects who continue (Continue arm) Only subjects who already are on treatment with ETV, TDF or TAF monotherapy, and have achieved sustained virologic suppression (<20 IU/mL), HBeAg negativity, normal ALT for more than 1 year (pretreatment HBeAg + pts) or 3 years (pretreatment HBeAg - pts), plus qHBsAg <200 IU/mL, and HBV RNA or HBcrAg negativity will be included in this study. One treatment arm will stop the NAs therapy while the other treatment arm will continue the NAs therapy. Participants in the Stop arm will be monitored very closely with special focus on clinical relapse. If any participant in the Stop NAs arm exceeds one or more predefined limits for such flares or relapses, NAs treatment will be reinstituted.

Through two-stage stratified cluster sampling, investigators studied the antiviral treatment rate and the main factors affecting the antiviral treatment in community chronic HBV infection-related liver disease population.

Based on the follow-up data of patients who underwent hepatectomy for HBV-related HCC at the First Affiliated Hospital of Xi'an Jiaotong University. patients who met the enrollment criteria were screened for tumor recurrence and survival for statistical analysis to understand the prognosis of patients and analyze the risk factors affecting their prognosis.
