Obstetric factors and mother-to-infant transmission of HIV-1

The Prevalence of HIV-Positive Infants Born to HIV-Positive Mothers Attended at the University of Gondar Specialized Hospital Anti-Retroviral Therapy Services, Northwest Ethiopia, 2018

Introduction

The human immunodeficiency virus (HIV) attacks the human immune cells and affects their function. It is the highest burden that occurs in a developing country. Ethiopia is one of the top ten countries in the world, which has a high burden of HIV-infected children. Even if the country works hard on the PMCT program, still there is challenging on MTCT reduction.

Objective

The purpose of this study was to assess the prevalence of HIV-positive infants born to HIV-positive mothers attending anti-retroviral treatment (ART) services at the University of Gondar specialized hospital, Gondar, northwest Ethiopia, 2018.

Methods

A retrospective chart review study was conducted from February to April 2018, among HIV-exposed infants who born to HIV-positive mothers in ART service at the University of Gondar specialized hospital. A systematic sampling method was applied to select study participants. Data were entered into EPI info version 7 statistical software and transferred to SPSS version 20 for analysis.

Results

In this study, 239 participants were enrolled, with a 98.8% response rate. The prevalence of HIV-positive infants born to HIV-positive mothers was 5.5% with a 95% CI (3.0–8.5%). Of the mothers, 77.1% were within 25–35 years of age range. Of the total infants, 56.8% were males. From these HIV-positive infants, 13 (5.5%) were born from age ranges of 25–35years old mothers, 9(3.8%) were females, 8(3.4%) were 6–11 months old, 13 (5.5%) were post-term gestation, and 13 (5.5%) were maternal CD4+ less than 350/mm³.

Conclusion and Recommendations

The prevalence of HIV-positive infants born to HIV-positive mothers in this study was lower than the previous 10.2%. To reduce such infant HIV infection to zero, it needs proactive action from stakeholders, health professionals, and the community at large.

HIV/AIDS epidemic in Turkey and use of antiretroviral drugs for treating pregnant women and preventing HIV infection in infants

Objective:

To evaluate changes in epidemiologic characteristics for HIV/AIDS in Turkey since 1985, management of HIV-positive pregnancies, and how new-borns and infants would be protected by anti-viral therapy (AVT).

Materials and Methods:

The World Health Organization (WHO) progress reports, 2013 UNAIDS Global AIDS epidemic reports, Turkish Ministry of Health HIV/AIDS reports, and distribution tables that we published for specific time frames (1985-2013) according to sex, age, age groups, and possible transmission routes were used and the groups were compared.

Results:

Although there were 35.3 (32.2-38.8) million people who were HIV(+) in the world as of 2013, only 9.7 million received AVTs. In Turkey, the total number of people with HIV/AIDS reported between 1985-2013 was 7050. There was a dramatic upward trend, with a peak in 2012 (n=1068). Sexually transmitted infection was the most common, and 4 drug use and blood transfusions showed a proportional increase. A total of 77 infections passed from mother to baby; seven cases have been reported in the last two years.

Conclusion:

Turkey is obliged to create an effective surveillance system for the prevention of HIV. The WHO proposed a new treatment protocol (option B+) in 2013 to prevent HIV mother-child transmission.

Risk factors and mechanisms of preterm delivery in Malawi

PROBLEM

We examined risk factors and mechanisms of preterm delivery (PTD) in malaria-exposed pregnant women in Blantyre, Malawi.

METHOD OF STUDY

The human immunodeficiency virus (HIV), malaria, syphilis, and anemia were assessed in a cross-sectional study of 572 pregnant women. In a nested case-control study, chorioamnionitis (CAM) was examined; tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, IL-8, macrophage inflammatory protein (MIP)-1alpha, monocyte chemotactic protein (MCP)-1, transforming growth factor (TGF)-beta, cortisol, and corticotropin-releasing hormone were measured in placental, maternal and/or cord blood.

RESULTS

HIV, infrequent antenatal clinic attendance, low-maternal weight, no intermittent preventive malaria therapy (IPT), and CAM were associated with PTD, while malaria was not. Of the 18 compartmental cytokine measurements, elevations in placental and/or cord IL-6 and IL-8 were associated with both CAM and PTD. In contrast, there was no overlap between the cytokines affected by malaria and those associated with PTD.

CONCLUSIONS

The HIV and CAM were the major infections associated with PTD in this study. CAM, but not malaria, causes PTD via its effect on proinflammatory cytokines.

Infant birth weight among women with or at high risk for HIV infection: the impact of clinical, behavioral, psychosocial, and demographic factors

The purpose of these analyses was to provide a prospective examination of the impact of HIV on birth weight using clinical, behavioral, psychosocial, and demographic correlates. HIV-positive (n = 319) and HIV-negative (n = 220) pregnant women matched for HIV risk factors (i.e., drug use and sexual risk behaviors) were interviewed during the 3rd trimester of pregnancy and 6 weeks postpartum. Medical chart reviews were also conducted for the HIV-seropositive pregnant women to verify pregnancy-related and birth outcome data. In a logistic regression analysis, model chi2(9, N = 518) = 124.8, p < .001, controlling for parity and gestational age, women who were HIV seropositive were 2.6 times more likely to have an infant with low birth weight. In addition, Black women and those who did not live with their partners were more than 2 times as likely to have infants with low birth weight, and those who smoked were 3.2 times more likely to have infants with low birth weight. Knowing that women with HIV, those who are Black, and those not living with a partner are at highest risk for adverse birth outcomes can help those in prenatal clinics and HIV specialty clinics to target resources and develop prevention interventions. This is particularly important for women with HIV because birth weight is associated with risk of HIV transmission from mother to child.

Human immunodeficiency virus infection in pregnancy

The incidence and prevalence of human immunodeficiency virus (HIV) infection in women of child-bearing age continue to increase both internationally and in Canada. The care of HIV-infected pregnant women is complex, and multiple issues must be addressed, including the current and future health of the woman, minimization of the risk of maternal-infant HIV transmission, and maintenance of the well-being of the fetus and neonate. Vertical transmission of HIV can occur in utero, intrapartum and postpartum, but current evidence suggests that the majority of transmission occurs toward end of term, or during labour and delivery. Several maternal and obstetrical factors influence transmission rates, which can be reduced by optimal medical and obstetrical care. Zidovudine therapy has been demonstrated to reduce maternal-infant transmission significantly, but several issues, including the short and long term safety of antiretrovirals and the optimal use of combination antiretroviral therapy in pregnancy, remain to be defined. It is essential that health care workers providing care to these women fully understand the natural history of HIV disease in pregnancy, the factors that affect vertical transmission and the management issues during pregnancy. Close collaboration among a multidisciplinary team of knowledgeable health professionals and, most importantly, the woman herself can improve both maternal and infant outcomes.
