Rubella Vaccination of Unknowingly Pregnant Women: The Sao Paulo Experience, 2001

Background. Rubella vaccination is contraindicated during pregnancy. During mass immunization of women of childbearing age against rubella, women unknowingly pregnant may be vaccinated. To evaluate the effects of rubella vaccination during pregnancy, the Brazilian state of Sao Paulo conducted a follow-up study of pregnant women vaccinated during a rubella campaign in 2001.Methods. Women vaccinated during pregnancy were reported to a national surveillance system. In the state of Sao Paulo, follow-up of vaccinated women included household interviews. Serum samples from vaccinated women were tested for antirubella antibodies to classify susceptibility to rubella infection. Children born to susceptible mothers were tested for evidence of congenital rubella infection and evaluated for signs of congenital rubella syndrome.Results. The Sao Paulo State Health Department received 6473 notifications of women vaccinated during pregnancy. Serology performed for 5580 women identified 811 (15%) that were previously susceptible. Incidence of spontaneous abortion or stillbirth among previously susceptible vaccinated women was similar to women with prior immunity. Twenty-seven (4.7%) of 580 newborns tested had evidence of congenital rubella infection; none had congenital rubella syndrome.Conclusions. Mass rubella vaccination of women of childbearing age was not associated with adverse birth outcomes or congenital rubella syndrome among children born to women vaccinated during pregnancy.

Genotipagem de HLA de classe I e II para seleção de células precursoras dendríticas para estudo da imunobiologia do vírus associado ao Sarcoma de Kaposi (KSHV)

The Kaposi-associated Herpesvirus (KSHV) also known as Human Herpesvirus 8 (HHV-8) is associated with the development of Kaposi’s sarcoma (KS) and others limphoprolipheratives diseases such as Primary Effusion Lymphoma (PEL) and Multicentric Castleman Disease (MCD). Even though the virus is considered lymphotropic, it is able to infect others cell types such as macrophages, dendritic cells, endothelial cells, monocytes and fibroblasts. After infection, KSHV be latent expressing essential viral genes to its maintenance in a infected cell. However, in some circumstances may occur the reactivation of lytic cycle producing new viral particles. K1 protein of KSHV interferes in the cellular signaling inducing proliferation and supporting cellular transformation. K1 is encoded by viral ORF-K1, which shows high variability between different genotypes of KSHV. So far, it is not clear whether different isoforms of K1 have specific immunobiological features. The KSHV latency is maintained under strict control by the immune system supported by an adequate antigen presentation involving Human Leucocyte Antigen (HLA) class I and II. Polymorphisms of HLA class I and II genes confer an enormous variability in molecules that recognize a large amount of antigens, but also can increase the susceptibility to autoimmune diseases. Therefore, the present study aims to genotype HLA class I (A and B) and class II (DR and DQ) from volunteers to identify haplotypes that can provide better response to K1 epitopes of different KSHV genotypes. First of all, 20 volunteers were selected to genotype HLA genes. In our results we observed prevalence of certain HLA class I haplotypes as HLAA1, HLA-A2, HLA-A24, HLA-A26, HLA-B8, HLA-B18 e HLA-B44. After the in silico analysis using BIMAS and SYFPEITHI databases, we observed high scores for epitopes from the B genotype of KSHV, indicating...(Complete abstract click electronic access below)

A longer time of exposure to antiretroviral therapy improves selenium levels

Background &aims: Selenium is an essential mineral for immunological function, performing crucial functions at the cellular level. This micronutrient has been determined to be frequently deficient in HIV infected patients, with correlations between reduced immunological function and greater susceptibility to opportunistic infections. Our aim was to evaluate the influence of time of exposure to antiretroviral therapy (ART) on the biochemical profile of selenium in HIV-infected patients.Methods: We performed a cross-sectional study on 50 HIV-positive men with different quantitations of viral load and CD4+ T cells, who were either receiving or not receiving ART. Dual energy X-ray absorptiometry (DXA) to determine body composition, biochemical analysis of selenium and albumin, anthropometric measurements were performed. The subjects were divided into groups according to the use of ART or not: The Control Group (CG) was 10 treatment-nave volunteers, Group G < 2 was 20 volunteers on ART for less than 2 years, and Group G > 2 was 20 volunteers on ART for >2 years.Results: The body mass index showed that all subjects were of normal weight. The group with a longer time of exposure to ART (G > 2) had undetectable viremia and a higher CD4+ T cell count: 593.1 +/- 234.6 mm(3). Selenium values (mu g/L) were 55.9 +/- 11.9 for CG, 52.1 +/- 10.5 for G < 2, and 66.9 +/- 20.8 for G > 2, with a significant difference between groups G < 2 and G > 2 (p < 0.05), and only G > 2 showed normal selenium values.Conclusions: Most of the men studied showed selenium deficiency, except for the subjects with a longer exposure to antiretroviral treatment. Thus, an adequate selenium concentration is related to better control of virology and of immunologic function. (C) 2014 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.
