BACKGROUND Efforts to monitor malaria transmission increasingly use cross-sectional surveys to estimate transmission intensity from seroprevalence data using malarial antibodies. To date, seroconversion rates estimated from cross-sectional surveys have not been compared to rates estimated in prospective cohorts. Our objective was to compare seroconversion rates estimated in a prospective cohort...
The reactogenicity and immunogenicity of combined measles and rubella (MR) booster vaccination, via aerosol and subcutaneous routes, was assessed in 562 healthy children. Rates of rubella seroconversion and geometric mean titers (GMT) were similar for both routes. Rates of measles PN seroconversion, GMT and measles ELISA post-vaccination seropositivity and seroconversion rate were each higher f...
We describe incidence and risk factors for pandemic (H1N1) 2009 virus infection in healthcare personnel during the June-September 2009 epidemic in Singapore. Personnel contributed 3 serologic samples during June-October 2009, with seroconversion defined as a ≥4-fold increase in hemagglutination inhibition titers to pandemic (H1N1) 2009. Of 531 participants, 35 showed evidence of seroconversion....
BACKGROUND AND AIMS Seroclearance or seroconversion of hepatitis B surface antigen (HBsAg) is generally considered as the clinical endpoint. The purpose of the present meta-analysis was to evaluate pegylated interferon alpha (PEG-IFNα) with or without lamivudine (LAM) or adefovir (ADV) combination treatment in HBsAg seroclearance or seroconversion with CHB. METHODS Randomized controlled trial...
BACKGROUND The association between human papillomavirus (HPV) infection and the risk of human immunodeficiency virus (HIV) seroconversion is unclear, and the genital cellular immunology has not been evaluated. METHODS A case-control analysis nested within a male circumcision trial was conducted. Cases consisted of 44 male HIV seroconverters, and controls were 787 males who were persistently n...
HBeAg seroconversion is an important stage in the evolution of a chronic hepatitis B virus (HBV) infection that usually leads to control of viral replication and a reduced risk for liver cirrhosis and cancer. Since current therapies for the HBV-associated liver inflammation that is known as chronic hepatitis B (CHB). Rarely induce permanent HBeAg seroconversion, there is a need to understand th...
واکسیناسیون هپاتیتb در تمام افراد hiv مثبت غیرایمن در برابرhbv توصیه شده است. اگرچه پاسخ سرولوژیکی به واکسیناسیون استانداردhbv در این جمعیت کمتراز حد مطلوب می باشد و راهکارمناسب برای واکسیناسیون مجددافراد hiv مثبت غیرپاسخ دهنده به واکسیناسیون هم چنان مورد بحث باقی مانده است. ما پاسخ سرولوژیکی به یک دوز اضافی واکسن hbv به روش داخل جلدی یا داخل عضلانی در افراد hiv مثبت غیر پاسخ دهنده به واکسیناسی...
Current treatments for human immunodeficiency virus (HIV) require uninterrupted drug administration because they are unable to reconstitute the immune response and do not affect the viral reservoir. Ten patients were treated during acute HIV infection before complete Western blot (WB) seroconversion with the combination of hydroxyurea, didanosine, and indinavir. This treatment was associated wi...
Background & Objectives: Hepatitis B is one of the major health problems in the world. Health care workers (HCWs) are at high risk of acquiring hepatitis B virus. The aim of this study was to evaluate the prevalence of HBV infection and the immune response to HBV vaccine among the HCWs in Babol, northern...
