Efficacy and Safety of DRG/3TC for Prophylaxis of HIV Perinatal Transmission: A Pilot Study (PREGNANCY).

Background: The prevention of perinatal human immunodeficiency virus (HIV) transmission depends on the safe and effective use of antiretroviral therapy (ART). Simplifying treatment reduces drug exposure for both mother and child. We evaluated the safety and efficacy of dolutegravir (DTG) plus lamivudine (3TC) for antiretroviral-naive pregnant women with HIV.

[Brazilian Protocol for Sexually Transmitted Infections 2020: infections causing vaginal discharge].

The topic of vaginal discharge is one of the chapters of the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020. The chapter has been developed based on scientific evidence and validated in discussions with specialists. This article presents epidemiological and clinical aspects related to vaginal discharge conditions, as well as guidelines for health service managers and health professionals about screening, diagnosing and treating these conditions, which are one of the main complaints among women seeking health services, and which may be caused by infectious or non-infectious factors.

Raltegravir versus lopinavir/ritonavir for treatment of HIV-infected late-presenting pregnant women.

Background Late-presenting pregnant women pose a challenge in the prevention of HIV-1 mother-to-child-transmission. We compared the safety and efficacy of raltegravir and lopinavir/ritonavir for this population. Methods We did a single-center, pilot, open-label, randomized trial in Brazil (N = 44).

Predictors of HPV incidence and clearance in a cohort of Brazilian HIV-infected women.

Persistent infection with high-risk human papillomavirus (HR-HPV) is necessary for the development of precursor lesions and cervical cancer. HPV infection among women living with HIV/AIDS (WLHA) occurs more frequently, presents a higher rate of persistent infections and an earlier progression to cancer. We aimed to evaluate HR-HPV prevalence, incidence and clearance, and its association with HIV viral suppression, immunological response and other risk factors among WLHA followed at an STD/HIV reference center.

High-risk papillomavirus infection among women living with human Immunodeficiency virus: Brazilian multicentric study.

Cervical cancer is an important health issue in Latin America. Although HPV infections can have spontaneous clearance, persistence of high-risk (HR) HPV is a risk factor for cervical cancer among women and it is even higher in HIV-infected women. To determine the prevalence of HR-HPV and risk factors among HIV-infected women attending reference services for HIV/AIDS in different regions of Brazil.

Prevalence of Chlamydia trachomatis and Neisseria gonorrhea and associated factors among women living with Human Immunodeficiency Virus in Brazil: a multicenter study.

Background: Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) cause infections in the female genital tract, increasing susceptibility to and infectiousness of HIV. The objectives of the present study were to determine the prevalence and associated factors of CT and GC infection among HIV-infected women in Brazil.

Methods: Cross-sectional study conducted from March to December 2015, including HIV-infected women attending referral centers in nine states of Brazil, aged 18-49 years, nonpregnant.

Anogenital infection by Chlamydia trachomatis and Neisseria gonorrhoeae in HIV-infected men and women in Salvador, Brazil.

Background: Infections caused by Chlamydia trachomatis and Neisseria gonorrhoeae are the most common bacterial sexually transmitted infections throughout the world. These sexually transmitted infections are a growing problem in people living with HIV/AIDS. However, the presence of these agents in extra genital sites, remains poorly studied in our country.

[Dual contraception adherence among HIV-infected women].

Purpose: To determine adherence to dual contraception using depot-medroxyprogesterone acetate (DMPA) and condom among HIV-infected women.

Methods: A cross-sectional study carried out from December 2013 to September 2014 at a local reference center, with application of questionnaire elaborated after Delphi panel and content validation to 114 HIV(+) women aged 15 to 49 years, using DMPA plus condom for contraception.

Results: Mean age was 33.

[Genotype distribution of human papillomavirus in women from the state of Bahia, Brazil].

Purpose: The aim of this study was to evaluate the human papillomavirus genotypes and the frequency of multiple human papillomavirus infections, as well as to assess the association between human papillomavirus genotype, cyto-histopathological abnormalities and age range.

Methods: A retrospective cross-sectional study was carried out between June 2010 and October 2013 in Salvador, Bahia, Brazil. We analyzed 351 results of positive human papillomavirus genotyping performed using the PapilloCheck(r) test, designed to detect 24 human papillomavirus types.

Short communication: Use of raltegravir in late-presenting HIV-infected pregnant women.

The risk of HIV-1 mother-to-child transmission (MTCT) is clearly correlated with the maternal HIV cell-free viral load (VL) at delivery. Preventing MTCT in late-presenting (after 28 weeks) HIV-infected pregnant women remains a clinical challenge, and ensuring a rapid decrease of maternal VL is an important preventive strategy. Raltegravir (RGV) has a higher first and second phase viral decay rate, has a high placental transfer, with a potential preloading effect for neonate, and demonstrates effective accumulation in cervicovaginal secretions.

Prevalence of sexually transmitted infections among HIV-infected women in Brazil.

This study aimed to evaluate the prevalence of sexually transmitted infections (STIs) and associated risk factors in HIV-infected pregnant women followed for prenatal care in Salvador, Bahia. This was a cross-sectional study of 63 women seeking prenatal care at a reference center. Participants were interviewed regarding socio-epidemiological and clinical history, and were tested for HBsAg, anti-HCV, anti HTLV I/II, VDRL, Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma hominis, Ureaplasma urealyticum, CD4 count, and HIV plasma viral load.

Comparative study of the expression of cellular cycle proteins in cervical intraepithelial lesions.

Interaction of human papilloma virus oncoproteins E6 and E7 with cell cycle proteins leads to disturbances of the cell cycle mechanism and subsequent alteration in the expression of some proteins, such as p16INK4a, cyclin D1, p53 and KI67. In this study, we compared alterations in the expression of these proteins during several stages of intraepithelial cervical carcinogenesis. Accordingly, an immunohistochemical study was performed on 50 cervical biopsies, including negative cases and intraepithelial neoplasias.

P16(INK4a) expression as a potential prognostic marker in cervical pre-neoplastic and neoplastic lesions.

An immunohistochemical analysis with monoclonal antibody p16(INK4a) was performed in formalin-fixed, paraffin-embedded samples of 60 cases. The aim was to investigate in biopsies the expression of p16(INK4a) of normal uterine cervical tissue, pre-cancerous and cancerous lesions, and their relation with human papilloma virus (HPV) and HIV status. Three parameters were evaluated: percentage of p16(INK4a) positive cells, reaction intensity, and cell staining pattern.

Prevalence of human Papilloma Virus in HIV-positive and HIV-negative patients in the State of Bahia: a pilot study.

Human Papilloma Virus (HPV) plays a central role in the development of cervical cancer. However, other coexisting factors, such as HIV infection, must be present for this to occur. We evaluated the prevalence of HPV in HIV-positive and HIV-negative patients in the city of Salvador, Bahia, Brazil, and determined the most prevalent types of HPV in these patients.
