Filter by:Human immunodeficiency virus/Hepatitis B virus (HIV/HBV) co-infections are frequently observed due to shared routes of transmission, with reported figures indicating 6-9% of HIV-infected individuals in developed countries are chronically infected with HBV. HIV infection impacts on the natural progression of HBV infection, increasing levels of HBV replication and the risk of liver-associated mortality. Liver diseases associated with HBV are affected by the antiviral drugs used for HIV infection (toxic side effects), the current immune function in the patient, by improvements in the immune system brought about by control of the HIV infection, and by the development of resistance to the antiviral agents used for both the hepatitis B and the HIV infection. Co-infection with HBV increases the risk for hepatotoxicity in those individuals receiving highly active antiretroviral therapy (HAART) for their HIV infection. This study will recruit patients who are co-infected with HIV and HBV, and are currently taking or who are about to commence HAART. The study cohort will include HIV-HBV co-infected individuals from the Alfred Hospital, the Royal Melbourne Hospital and high case load GP clinics who are referred to the Alfred Hospital. The aim of the study is to investigate chronic hepatitis B and its impact on the progression of liver disease in HIV-infected persons receiving HAART. This will be achieved by 6 monthly assessment with medical history, physical examination, bloods for markers of liver disease and hepatitis B activity and completion of questionnaires to measure adherence and alcohol use.
Percutaneous liver biopsy (PLB) is the gold standard for grading necroinflammation and staging fibrosis in patients with chronic viral hepatitis. Whether the use of 1-deamino-8-D-arginine vasopressin (DDAVP) before PLBs in hemodialysis (HD) patients with chronic viral hepatitis has comparable safety profiles to those with normal renal function (NRF) has not been evaluated in prospective studies.
By detecting polymorphisms of IL-1β and TNF-α,this study aims to find the effects of cytokine gene polymorphisms(and their interaction) on susceptibility and severity of HBV-related HCC.
The purpose of this booster study is to evaluate, in subjects primed in the primary study 106786, the persistence, at the time of the booster vaccination, of antibodies elicited by the different formulation of DTPa-HBV-IPV/ Hib vaccine (Infanrix Hexa TM). The study will also evaluate the immune response of these subjects to a DTPa-HBV-IPV/Hib booster. This protocol posting deals with the objectives and outcome measures of the booster phase. The objectives and outcomes measures of the primary phase are presented in a separate protocol posting (NCT = 00376779).
This is a randomized, open-labelled, prospective 96-week study comparing the antiviral efficacy and safety of switching to entecavir 1 mg QD from lamivudine versus maintaining lamivudine 100 mg QD treatment in HBV-infected subjects currently receiving lamivudine monotherapy.
This is a randomized, open-labelled, prospective 96-week study comparing the antiviral efficacy and safety of switching to entecavir 0.5mg QD from lamivudine versus maintaining lamivudine 100mg QD treatment in CHB patients currently receiving lamivudine monotherapy.
This is a follow-up of Study A3L10 (NCT00315055) Immunogenicity - To describe the antibody persistence following a primary series vaccination of either DTaP-IPV-HB-PRP~T or PENTAXIM™ and ENGERIX B®. - To describe the immunogenicity of a booster dose of DTaP-IPV-HB-PRP~T. Safety - To describe the safety profile after a booster dose of DTaP-IPV-HB-PRP~T.
The purpose of this study is to evaluate the safety and immunogenicity of an indigenously developed liquid pentavalent (diphtheria, tetanus, pertussis, hepatitis B and Hib) combination vaccine in healthy Indian infants as a part of the routine immunization in accordance with the EPI schedule.
This 3 arm study will assess the efficacy and safety of PEGASYS + entecavir combination therapy in treatment-naive patients with HBeAg positive chronic hepatitis B. Patients will be randomized to receive 1)PEGASYS 180 micrograms s.c./week for 48 weeks, 2)PEGASYS 180 micrograms s.c./week for 48 weeks + entecavir 0.5mg p.o. once daily from week 13 to week 36 or 3) entecavir 0.5mg p.o. once daily for 24 weeks + PEGASYS 180 micrograms s.c./week from week 21 to 68. Treatment will be followed by 24 weeks treatment-free follow up. The anticipated time on study treatment is 3-12 months for groups 1 and 2, and 1-2 years for group 3, and the target sample size is 100-500 individuals.
The new formulation administered as a 4th consecutive dose will be compared to the current formulation of the vaccine in this partially double blind study. The study will be double-blind with respect to the two DTPa-HBV-IPV/Hib groups. The study will be open with respect to the DTPa-HBV-IPV group.
