BACKGROUND The aim of this study was to assess the efficacy and safety of peginterferon α-2a (pegIFN) and nucleos(t)ide analogues (NA) treatments in patients with hepatitis B envelope antigen (HBeAg)-positive chronic hepatitis B (CHB) with mild acute exacerbation (AE). METHODS Treatment-naive HBeAg-positive CHB patients with AE who received pegIFN or NA (entecavir (ETV) or telbivudine (LDT)) ...
INTRODUCTION The incidence of recent hepatitis C virus infection (HCV) infection has been noted to be increasing among men who have sex with men (MSM), especially those with HIV infection, in several resource-rich settings. In Taiwan, the incidence of recent HCV infection increased from 0 in 1994-2000, 2.29 in 2001-2005 to 10.13 per 1000 person-years of follow-up (PYFU) in 2006-2010. In this st...
In England, during pandemic 2009 H1N1, vaccine efficacy and immunogenicity population studies in priority groups were rolled out in parallel to evaluate the pandemic vaccination programme. This provided a unique opportunity to compare immunogenicity and clinical protection in the same population and thus provide insights into the correlates of protection for the pandemic H1N1 2009 vaccine in ri...
During 2000 to 2009, data on people undergoing HIV testing and on those newly diagnosed with HIV were collected in a network of 20 Spanish clinics specialising in sexually transmitted infections and/or HIV testing and counselling. The number of tests performed, overall and disaggregated by different variables, was obtained. HIV prevalence among first-time testers and HIV incidence among repeat ...
The Norwegian pig population has been free from influenza viruses until 2009. The pandemic influenza outbreak during the autumn 2009 provided an opportunity to study the clinical impact of this infection in an entirely naïve pig population. This paper describes the results of a case-control study on the clinical impact of pandemic influenza (H1N1) 2009 infection in the nucleus and multiplier he...
OBJECTIVE Chronic hepatitis B (CHB) is a major health problem. The outcome of hepatitis B virus (HBV) infection is associated with variations in HLA-DPA1 alleles. The aim of this study was to investigate possible associations of HLA-DPA1 alleles with treatment response and with hepatitis B virus e antigen (HBeAg) seroconversion. METHODS Eight different HLA-DPA1 alleles from 246 CHB patients w...
To determine whether West Nile virus (WNV) had reached the archipelago of Guadeloupe, a serologic study in horses and birds was conducted in 2002. Immunoglobulin (Ig) G, IgM, enzyme-linked immunosorbent assay, and seroneutralization tests identified WNV infection in horses and chickens. Six months later, a high rate of seroconversion was observed in horses.
Salmonella typhi Ty21a vaccine in a liquid formulation was evaluated in 634 Thai children 2 to 6 years of age. The seroconversion rate was 69% for those who received vaccine versus 14% for those who received placebo (P < 0.005). The immune responses among vaccine recipients ranged from 60% in 3-year-olds to 81% for 6-year-olds.
IMPORTANCE Type 1 diabetes usually has a preclinical phase identified by circulating islet autoantibodies, but the rate of progression to diabetes after seroconversion to islet autoantibodies is uncertain. OBJECTIVE To determine the rate of progression to diabetes after islet autoantibody seroconversion. DESIGN, SETTING, AND PARTICIPANTS Data were pooled from prospective cohort studies perf...
The aim of the present study was to investigate the effect of the traditional Chinese medicine paiteling on the outcome of high-risk human papillomavirus (HR-HPV) infection of the cervix. A total of 321 patients were enrolled in this study and HPV subtypes were determined by the Hybribio HPV genotyping system. The patients were divided into the loop electrosurgical excision procedure (LEEP; n=8...
