This study aimed to estimate the prevalence of biomarkers for hepatitis A, B, and C among young and adolescent MSM and TGW in three Brazilian municipalities. METHODS: Baseline data were collected from a combination of HIV prevention cohort of young […]

ABSTRACT OBJECTIVE To determine the seroprevalence of hepatitis B and C among immigrants residing refugee camps in Muzaffarabad, Azad Kashmir, Pakistan, and to identify possible risk factors for hepatitis B virus (HBV) and hepatitis C virus (HCV) transmission. METHODS Around 1,225 individuals inhabiting Muzaffarabad refugee camps, participated in the study. A qualitative Immuno-Chromatographic Technique was used for initial screening and PCR test was used for detection of HBV and HCV in participants. The major risk factors for HBV and HCV […]

METHODS: Hypothetical cohort of patients with CHB, HBeAg-negative, without clinical or histological evidence of cirrhosis, detectable HBV DNA, histological diagnosis of the disease, positive serum HBsAg for longer than six months, high levels of alanine aminotransferase (ALT) (twice as high as the upper limit of normality) and mean age of […]

OBJECTIVE: To describe the epidemiological and genotypic profile of chronic hepatitis B infection in Northern Portugal. METHODS: This survey comprised 358 subjects with positive serology for hepatitis B antigen for at least six months, recruited from specialist appointments in two hospitals in Northern Portugal between 2008 and 2009. Data were obtained from patient files, laboratory tests performed at the time of viral genotyping, echograms and/or ultrasonogram results, and liver biopsies. Demographic characteristics, viral markers, viral load and genotype, and severity […]

OBJECTIVE: To evaluate the immunogenicity and safety of a novel hepatitis B vaccine, after increasing antigen concentration to 25 μg, in comparison to the reference vaccine. METHODS: Single-blinded randomized trial comparing VrHB-IB (Instituto Butantan) and the reference vaccine (Engerix B®, Glaxo Smith Kline). Volunteers aged 31 to 40 years were randomized to either experimental (n=216) or control (n=203) groups, and were given three doses of vaccine. The first dose was administered upon recruitment, and the second and third doses 30 […]

OBJECTIVE: To analyze the efficacy and safety of a recombinant Hepatitis B vaccine in newborns. METHODS: The study was carried out in a general hospital in the city of Guarulhos, Southeastern Brazil, between 2002 and 2005. The recombinant Hepatitis B vaccine from Instituto Butantan (VrHB-IB) was tested in two clinical trials. In both trials, newborns were randomly allocated to the experimental or control (reference vaccine) groups. Newborns were given three doses of vaccine, one up to 24 hours after birth […]

OBJECTIVE: To describe the profile of injecting drug users living with HIV/AIDS and estimate hepatitis B and hepatitis C prevalence rates within this group. METHODS: Cross-sectional study conducted with 205 injecting drug users living with HIV/AIDS receiving attention in three public health clinics in the city of Sao Paulo, in 2003. A non-probabilistic sample of volunteers was selected consecutively on the days respondents appeared for their appointments at the clinics.
