1. Perforin gene PRF1 c.900C> T polymorphism and HIV-1 vertical transmission
Abstract Perforin-1, a component of the immune system, is able to control Human Immunodeficiency Virus-1 (HIV-1) replication and could be involved in HIV-1 mother-to-child transmission (MTCT). This study aims at evaluating the role of the c.900C > T PRF1 gene (encoding for perforin-1) polymorphism (rs885822) in HIV-1 MTCT. The PRF1 c.900C > T polymorphism wa

2. HIV-1 mother-to-child transmission in Brazil (1994-2016): a time series modeling
Abstract HIV-1 mother-to-child transmission (HIV-1 MTCT), is an important cause of children mortality worldwide. Brazil has been traditionally praised by its HIV/Aids program, which provides free-of-charge care for people living with HIV-1. Using public epidemiology and demographic databases, we aimed at modeling HIV-1 MTCT prevalence in Brazil through the y

3. Factors associated with prenatal care and HIV and syphilis testing during pregnancy in primary health care
ABSTRACT OBJECTIVE To evaluate the factors associated with HIV and syphilis testing during pregnancy in Brazil. METHODS This was an ecological study covering all Brazilian municipalities evaluated by the second cycle of the National Program for Access and Quality Improvement in Primary Care, 2013-2014. The dependent variables were based on prenatal care

4. Review of the missed opportunities for the prevention of vertical transmission of HIV in Brazil
OBJECTIVE: The present literature review aims to highlight gaps in the treatment of preventative mother-to-child HIV transmission and the risk factors in Brazil. METHODS: Among the 425 articles identified in SciELO and PubMed searches, 59 articles published between 1994 and 2016 were selected for reading and data extraction, and 33 articles were included i

5. Entre a mulher e a salvação do bebê: experiências de parto de mulheres com HIV
O artigo analisa a experiência de parto de mulheres com HIV na perspectiva da bioética feminista. Trata-se de um estudo de casos múltiplos com seis mulheres entrevistadas na gestação e três meses depois do parto. Como resultados, apontamos a pouca participação na escolha da via de parto, a falta de orientações no pré-natal, inclusive quanto à pre

6. HLA-B*14 allele predicts HIV-1 mother-to-child-transmission, in Salvador, Brazil
ABSTRACT Background: Class I human leukocyte antigens, especially the molecules encoded at the B locus (HLA-B), are associated with AIDS progression risk. Different groups of HLA-B alleles have been associated to a protective effect or increasing susceptibility to HIV infection and are expressed from the earliest stages of gestation. Objective: The aim of

7. A SYSTEMATIC REVIEW ON THE INFLUENCE OF HLA-B POLYMORPHISMS ON HIV-1 MOTHER-TO-CHILD-TRANSMISSION
ABSTRACT Background: Mother-to-child-transmission (MTCT) is the main route of HIV-1 infection in children. Genetic studies suggest HLA-B alleles play an important role on HIV-1 transmission, progression, and control of HIV-1 infection. Objective: To evaluate which polymorphisms of HLA-B are involved in HIV-1 MTCT. Methods: Two independent reviewers perfor

8. HIV-1 genetic diversity and resistance to antiretroviral drugs among pregnant women in Ribeirão Preto (SP), Brazil. Cross-sectional study
ABSTRACT BACKGROUND: Increasing genetic diversity of HIV-1 and emergence of drug-resistant mutations may reduce the efficacy of antiretroviral therapy and prophylaxis that are used to prevent mother-to-child transmission. The aim of this study was to assess the genetic diversity and prevalence of drug-resistant mutations among HIV-infected pregnant women.

10. Effectiveness of the prevention of mother-to-child HIV transmission in Bahia, Brazil
ABSTRACTINTRODUCTION: Antiretroviral therapy and prophylaxis during the antepartum, intrapartum and postpartum periods, cesarean delivery and avoidance of breast milk significantly reduce vertical transmission of HIV.OBJECTIVE:To evaluate the effectiveness prevention of mother-to-child transmission of HIV and determine the rate of vertical transmission in a

11. Lactotransferrin gene functional polymorphisms do not influence susceptibility to human immunodeficiency virus-1 mother-to-child transmission in different ethnic groups
Lactotransferrin, also known as lactoferrin, is an iron binding glycoprotein that displays antiviral activity against many different infectious agents, including human immunodeficiency virus (HIV)-1. Lactotransferrin is present in the breast milk and in the female genitourinary mucosa and it has been hypothesised as a possible candidate to prevent mother-to-

12. Incidence of antiretroviral adverse drug reactions in pregnant women in two referral centers for HIV prevention of mother-to-child-transmission care and research in Rio de Janeiro, Brazil
Mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) infection remains an important cause of new HIV infections worldwide, especially in low and middle-resource limited countries. Safety data from studies involving pregnant women and prenatal antiretroviral (ARV) exposure are still needed once these studies are often small and with a lim
