Prevention of mother-to-child transmission of HIV

Ethical issues surrounding the provider initiated opt--Out prenatal HIV screening practice in Sub-Saharan Africa: a literature review

Background

Prevention of mother to child transmission of HIV remains a key public health priority in most developing countries. The provider Initiated Opt – Out Prenatal HIV Screening Approach, recommended by the World Health Organization (WHO) lately has been adopted and translated into policy in most Sub – Saharan African countries. To better ascertain the ethical reasons for or against the use of this approach, we carried out a literature review of the ethics literature.

Methods

Papers published in English and French Languages between 1990 and 2015 from the following data bases were searched: Pubmed, Cochrane literature, Embase, Cinhal, Web of Science and Google Scholar. After screening from 302 identified relevant articles, 21 articles were retained for the critical review.

Discussion

Most authors considered this approach ethically justifiable due to its potential benefits to the mother, foetus and society (Beneficence). The breaching of respect for autonomy was considered acceptable on the grounds of libertarian paternalism. Most authors considered the Opt - Out approach to be less stigmatizing than the Opt - In. The main arguments against the Opt - Out approach were: non respect of patient autonomy, informed consent becoming a meaningless concept and the HIV test becoming compulsory, risk of losing trust in health care providers, neglect of social and psychological implications of doing an HIV test, risk of aggravation of stigma if all tested patients are not properly cared for and neglect of sociocultural peculiarities.

Conclusions

The Opt – Out approach could be counterproductive in case gender sensitive issues within the various sociocultural representations are neglected, and actions to offer holistic care to all women who shall potentially test positive for HIV were not effectively ascertained. The Provider Initiated Opt – Out Prenatal HIV Screening option remains ethically acceptable, but deserves caution, active monitoring and evaluation within the translation of this approach into to practice.

Aplicação do protocolo do "Projeto Nascer Maternidades" em uma maternidade de referência em Feira de Santana, Bahia, Brasil

OBJETIVOS: analisar a aplicação do protocolo do "Projeto Nascer Maternidades", estratégia do Ministério da Saúde para a adoção de medidas profiláticas e/ou terapêuticas no momento do parto, para gestantes com sorologias para sífilis/Aids desconhecidas, no primeiro ano de implantação em uma maternidade de referência em Feira de Santana, Bahia, Brasil. MÉTODOS: foram analisadas sorologias para HIV e sífilis solicitadas no pré-natal e na maternidade e a adoção de medidas profiláticas e/ou terapêuticas. Os dados foram coletados em uma amostra randomizada de 337 prontuários de gestantes admitidas para assistência obstétrica no período de julho de 2003 a julho de 2004. RESULTADOS: no pré-natal, 8,4% das gestantes realizaram sorologia para HIV e 8% para sífilis. Na maternidade, o teste rápido para HIV foi realizado para 17,7% das gestantes e o VDRL para 97,8%. A profilaxia das gestantes infectadas pelo HIV foi aplicada no momento do parto. Quanto à sífilis, não houve tratamento para 80% das mulheres com VDRL reagente. Os recém-nascidos foram tratados. CONCLUSÕES: as determinações do "Projeto Nascer-Maternidades" não foram seguidas no primeiro ano de implantação na maternidade estudada.

Acceptability of intrapartum HIV counselling and testing in Cameroon

BACKGROUND

To assess the acceptability of intrapartum HIV testing and determine the prevalence of HIV among labouring women with unknown HIV status in Cameroon.

METHOD

The study was conducted in four hospitals (two referral and two districts hospitals) in Cameroon. Labouring women with unknown HIV status were counselled and those who accepted were tested for HIV.

RESULTS

A total of 2413 women were counselled and 2130 (88.3%) accepted to be tested for HIV. Of the 2130 women tested, 214 (10.1%) were HIV positive. Acceptability of HIV testing during labour was negatively associated with maternal age, parity and number of antenatal visits, but positively associated with level of education. HIV sero-status was positively associated with maternal age, parity, number of antenatal visits and level education.

CONCLUSION

Acceptability of intrapartum HIV testing is high and the prevalence of HIV is also high among women with unknown HIV sero-status in Cameroon. We recommend an opt-out approach (where women are informed that HIV testing will be routine during labour if HIV status is unknown but each person may decline to be tested) for Cameroon and countries with similar social profiles.

Rapid HIV screening for women in labor

Women now comprise approximately half of all HIV-infected individuals and the epidemic of pediatric HIV disease continues unabated in the developing world. The issue of mother-to-child transmission has been a major concern for public health officials since the early years of this epidemic. Not uncommonly, the first opportunity to ascertain the HIV status is when a woman presents to a hospital in labor. Rapid HIV tests can provide fast results, allowing time for the provider to offer antiretroviral therapy. Several effective antiretroviral regimens are now available for the intrapartum patient whose rapid HIV test comes back as positive. Antiretroviral therapy should be initiated as soon as possible after a positive rapid HIV test result and prior to standard confirmatory testing. This article summarizes the epidemiology of HIV and focuses on testing policies, technologies for rapid screening for HIV infection and antiretroviral regimens that can reduce the risk of perinatal transmission from the intrapartum patient whose rapid HIV test comes back positive.

Making the choice: the translation of global HIV and infant feeding policy to local practice among mothers in Pune, India

In 2003, India had over 5.1 million infected individuals living with HIV/AIDS. The percentage of all HIV cases attributed to perinatal transmission has been increasing steadily from 0.33% of total cases in 1999 to 2.80% in 2004. Recent statistics indicate that over 130,000 infants have been infected through this route. Despite recent advances in reducing in utero and interpartum transmission with the use of antiretrovirals, there is a critical need to make infant feeding safer. Current UNAIDS/WHO/UNICEF recommendations stress avoidance of all breast-feeding if replacement feeding fulfills the key requirements of being affordable, feasible, acceptable, sustainable, and safe. In this paper, we examine how the UNAIDS/WHO/UNICEF recommendations have been actualized within the context of an urban government hospital in India. The documented patterns of infant feeding by HIV-positive mothers in Pune, India, from 2000 to 2004, highlight the complexities of making an informed and healthy choice under suboptimal conditions. The data indicate that interpersonal variations in the key requirements greatly influence the optimal practice to minimize mortality risks. Moreover, local information on health outcomes is crucial to tailoring policy recommendations to save lives. We propose the development of a decision-making algorithm that includes factors affecting mother-to-infant transmission, including site-specific data on health risks to the mother and the child. Such an algorithm would allow identification of the healthiest feeding choice and would minimize the pitfalls of promoting homogeneous practices lacking site-specific evidence-based evaluation.

Neonatal HIV infection

The purpose of this article is to describe the pertinent issues related to mother-to-child transmission of HIV infection. Significant succcss has been achieved in developed countries to reduce the incidence of this devastating disease in neonates through screening of pregnant women, maternal antiretroviral therapy to reduce transmission, and cesarean section for delivery. Prophylaxis continues for the first six weeks of the newborn's life with antiretroviral therapy and careful monitoring of clinical well-being. Antiretroviral therapy offers significant reduction in the rate of mother-to child transmission, and this is presently the cornerstone of therapy for the HIV-infected pregnant woman. Clinical studies of treatment modalities continue to offer new hope to prevent transmission of the virus to the fetus. Care for the HIV infected newborn is highly complex and constantly evolving. All neonatal nurses should be aware of these issues so that they can be partners in the identification of new cases and the ongoing treatment of babies who are infected.

The evolving art of caring for pregnant women with HIV infection

Care for the pregnant woman who has human immunodeficiency virus (HIV) is highly complex and constantly evolving. The purpose of this article is to describe the pertinent issues regarding women and HIV during pregnancy, including epidemiology of mother-to-child transmission, the effect of the disease on pregnancy, care issues in the perinatal period, and the issues in women's lives that place them at risk for HIV infection. Antiretroviral therapy offers significant reduction in the rate of mother-to-child transmission, and this is presently the cornerstone of therapy for the pregnant woman with HIV. Careful intrapartum management may also reduce the risk of transmission. Clinical studies of treatment modalities continue to offer new hope to prevent transmission of the virus to the fetus.
