Mother-to-child transmission of HIV in the Southern Region of Santa Catarina, from 2005 to 2015: analysis of risk factors to seroconversion in newborns

Sociodemographic profile and gestacional aspects of women with hiv/aids in Curitiba, Brazil

OBJECTIVE

To describe the sociodemographic and gestational profile of HIV-positive women in Curitiba-PR, years 2018-2020.

METHOD

Observational, cross-sectional research, with data obtained from the Information System of Diseases of Notification of Pregnant Women. Data were analyzed for consistency exploration, description and analysis.

RESULTS

The sample consisted mostly of women aged 13-30 years, white and with incomplete elementary school. Prenatal care was performed by 93.8% of pregnant women, 66.1% of whom knew their serological status before prenatal care and 45% received notification in the first gestational trimester. Access to antiretroviral medication occurred for 82.4% of pregnant women and for 74.6% the pregnancy outcome was alive newborns. The statistical variables associated with prenatal care were pregnancy evolution, ART prophylaxis, type of delivery and ART at delivery (p<0.00).

CONCLUSION

The pregnant women in the sample presented desired gestational indicators. The collected data allowed describing the sample's profile and evaluating the performance of the health policy for pregnant women.

[Evaluation of missed opportunities in the control of vertical HIV transmission in Rio Branco, Acre State, Brazil]

Vertical HIV transmission is still an important global public health problem. This study aimed to verify vertical HIV transmission in Rio Branco, Acre, Brazil, and to assess the possibility of its elimination. A cross-sectional study was conducted of HIV in pregnant women and a longitudinal study on the incidence of vertical HIV transmission in pregnant women living in the municipality (county) of Rio Branco in 2007-2015. The cohorts of pregnant women consisted of women who had liveborn children, stillbirths, or abortions. The data were obtained from the Brazilian Information System for Notificable Diseases (SINAN), Brazilian Information System on Live Births (SINASC), Brazilian Mortality Information System (SIM), and Brazilian Hospital Information Systems (SIH). Databases. Probabilistic database linkage was performed with the OpenRecLink software. The authors calculated the HIV prevalence rate in pregnant women, the vertical transmission rate, and the principal associated factors. HIV prevalence in pregnant women showed an upward trend, and the mean prevalence was 0.18%. Variables statistically associated with the occurrence of HIV in pregnant women were maternal age ≥ 20 years (p = 0.007), lower schooling (p = 0.054), and unmarried conjugal status/without partner (p = 0.001). Vertical HIV transmission was 6.9%. Use of antiretroviral therapy (ART) during prenatal care, even among pregnant women that already knew they were HIV-positive, was less than 90%. The elective cesarean rate was less than 60%, and the use of ART during delivery and by the newborn in the first 24 hours showed variations, depending on the period in which the maternal diagnosis was made. Although the strategies for the elimination of vertical HIV transmission are well established, this study's results point to important flaws in the cascade of care for HIV-infected pregnant women in Rio Branco.
