In this article, we describe the pathogens for which study participants showed seroconversion
before and after a tour of duty and the incidence of those seroconversions
within the military population.
Even as antiretroviral therapies began making inroads into the AIDS epidemic, the virulence of HIV-1 increased and the time from seroconversion
to a significant CD4-cell drop was cut in half, investigators reported at the Conference on Retroviruses and Opportunistic Infections 2014.
Leung, who heads the division of pediatric allergy and immunology at National Jewish Health, Denver, reported that seroprotection and seroconversion
rates for the three influenza strains included in the vaccine (B, H1N1, and H3N2) were not significantly different for AD and control subjects who received intradermal vaccination.
The study evaluated the rate of progression to T1D in high-risk children (HLA DR/DQ genotype and 2 or more first-degree relatives with T1D) after islet autoantibody seroconversion
According to the results, an increased hazard ratio of islet autoantibody seroconversion
was associated with respiratory infections during the first six months of life and ages 6 to almost 12 months.
A cohort of human immunodeficiency virus (HIV)-infected individuals with documented vaccine-induced hepatitis B surface antibody (HBsAb) seroconversion
was evaluated retrospectively to determine factors associated with loss of protective levels of HBsAb.
Results also showed that men infected with HIV maintained viral loads associated with a high risk of HIV transmission for around three-quarters of the time during the two years after seroconversion
, despite the fact that the majority were not eligible for antiretroviral treatment owing to having CD4 cell counts above 350 cells/mm[m.
Non-inferiority criteria were met separately for children in the sub-groups 6 months through 35 months of age and 3 years through 8 years of age as measured by geometric mean titers (GMTs) and seroconversion
Both studies evaluated the activity of Gardasil in two ways--by measuring geometric mean titer antibody * activity produced by the vaccine against the four HPV types, and by measuring seroconversion
rates for HPV-6, 11, 16, and 18.
It was also found that the Multimeric-001, when used in conjunction with a commercially available strain-dependant seasonal influenza vaccine (trivalent inactivated vaccine, or TIV), enhances the performance of the TIV by increasing the rates of Hemagglutination Inhibition (HI) seroconversion
to influenza strains both included, and not-included, in the TIV itself.
72), a result in keeping with an acute HIV infection and seroconversion
Limited decreases in oropharyngeal and cloacal viral shedding and mixed results were attained when looking at seroconversion
