          Abstract

          Background:

          The uptake of prevention of mother-to-child-transmission (PMTCT) services has improved in South Africa but challenges remain, including adherence to the World Health Organization's (WHO) PMTCT recommendations of exclusive breastfeeding (EBF), taking antiretroviral medication (ARV); testing for early infant diagnosis; and reducing stigma. Women who practice EBF for the first 6 months are less likely to transmit HIV to their infants, yet only 7% of women EBF for 6 months in South Africa. Adherence to these recommendations remains challenging because of difficulties relating to disclosure and stigma. To address this challenge, the feeding buddy concept was developed based on studies where ARV buddies have proved effective in providing support for women living with HIV. Buddies have demonstrated a positive effect on providing emotional and social support to adhere to PMTCT guidelines.

          Methods:

          A cluster randomized controlled trial was conducted in 16 selected randomly assigned clinics in uMhlathuze and uMlalazi districts of KwaZulu Natal, South Africa. HIV-positive pregnant women (n = 625) who intended to breastfeed were enrolled at 8 control clinics and 8 intervention clinics. The clinics were stratified on the basis of urban/rural/periurban locale and then randomly allocated to either intervention or control. In the intervention clinics, the mother chose a feeding buddy to be enrolled alongside her. Quantitative interviews with mothers and their chosen buddies took place at enrollment during pregnancy and at routine postdelivery visits at day 3 and weeks 6, 14 and 22. Women in the control clinics were followed using the same evaluation schedule. The trial evaluated the effect of a voluntary PMTCT feeding buddy program on HIV-infected women's adherence to PMTCT recommendations and stigma reduction. The proportion of women exclusively feeding at 5.5 months postpartum was the primary end-point of the trial. In-depth interviews were conducted among a convenience sample of PMTCT counselors, community caregivers, mothers, and buddies from intervention clinics and control clinics to document their overall experiences.

          Discussion:

          The information collected in this study could be used to guide recommendations on how to build upon the current South Africa. PMTCT “buddy” strategy and to improve safe infant feeding. The information would be applicable to many other similar resource poor settings with poor social support structures.

          Barriers and facilitating factors to the uptake of antiretroviral drugs for prevention of mother-to-child transmission of HIV in sub-Saharan Africa: a systematic review

          Objectives To investigate and synthesize reasons for low access, initiation and adherence to antiretroviral drugs by mothers and exposed babies for prevention of mother-to-child transmission (PMTCT) of HIV in sub-Saharan Africa. Methods A systematic literature review was conducted. Four databases were searched (Medline, Embase, Global Health and Web of Science) for studies conducted in sub-Saharan Africa from January 2000 to September 2012. Quantitative and qualitative studies were included that met pre-defined criteria. Antiretroviral (ARV) prophylaxis (maternal/infant) and combination antiretroviral therapy (ART) usage/registration at HIV care and treatment during pregnancy were included as outcomes. Results Of 574 references identified, 40 met the inclusion criteria. Four references were added after searching reference lists of included articles. Twenty studies were quantitative, 16 were qualitative and eight were mixed methods. Forty-one studies were conducted in Southern and East Africa, two in West Africa, none in Central Africa and one was multi-regional. The majority (n=25) were conducted before combination ART for PMTCT was emphasized in 2006. At the individual-level, poor knowledge of HIV/ART/vertical transmission, lower maternal educational level and psychological issues following HIV diagnosis were the key barriers identified. Stigma and fear of status disclosure to partners, family or community members (community-level factors) were the most frequently cited barriers overall and across time. The extent of partner/community support was another major factor impeding or facilitating the uptake of PMTCT ARVs, while cultural traditions including preferences for traditional healers and birth attendants were also common. Key health-systems issues included poor staff-client interactions, staff shortages, service accessibility and non-facility deliveries. Conclusions Long-standing health-systems issues (such as staffing and service accessibility) and community-level factors (particularly stigma, fear of disclosure and lack of partner support) have not changed over time and continue to plague PMTCT programmes more than 10 years after their introduction. The potential of PMTCT programmes to virtually eliminate vertical transmission of HIV will remain elusive unless these barriers are tackled. The prominence of community-level factors in this review points to the importance of community-driven approaches to improve uptake of PMTCT interventions, although packages of solutions addressing barriers at different levels will be important.

            Mother-to-child transmission of HIV-1 infection during exclusive breastfeeding in the first 6 months of life: an intervention cohort study.

            Exclusive breastfeeding, though better than other forms of infant feeding and associated with improved child survival, is uncommon. We assessed the HIV-1 transmission risks and survival associated with exclusive breastfeeding and other types of infant feeding. 2722 HIV-infected and uninfected pregnant women attending antenatal clinics in KwaZulu Natal, South Africa (seven rural, one semiurban, and one urban), were enrolled into a non-randomised intervention cohort study. Infant feeding data were obtained every week from mothers, and blood samples from infants were taken monthly at clinics to establish HIV infection status. Kaplan-Meier analyses conditional on exclusive breastfeeding were used to estimate transmission risks at 6 weeks and 22 weeks of age, and Cox's proportional hazard was used to quantify associations with maternal and infant factors. 1132 of 1372 (83%) infants born to HIV-infected mothers initiated exclusive breastfeeding from birth. Of 1276 infants with complete feeding data, median duration of cumulative exclusive breastfeeding was 159 days (first quartile [Q1] to third quartile [Q3], 122-174 days). 14.1% (95% CI 12.0-16.4) of exclusively breastfed infants were infected with HIV-1 by age 6 weeks and 19.5% (17.0-22.4) by 6 months; risk was significantly associated with maternal CD4-cell counts below 200 cells per muL (adjusted hazard ratio [HR] 3.79; 2.35-6.12) and birthweight less than 2500 g (1.81, 1.07-3.06). Kaplan-Meier estimated risk of acquisition of infection at 6 months of age was 4.04% (2.29-5.76). Breastfed infants who also received solids were significantly more likely to acquire infection than were exclusively breastfed children (HR 10.87, 1.51-78.00, p=0.018), as were infants who at 12 weeks received both breastmilk and formula milk (1.82, 0.98-3.36, p=0.057). Cumulative 3-month mortality in exclusively breastfed infants was 6.1% (4.74-7.92) versus 15.1% (7.63-28.73) in infants given replacement feeds (HR 2.06, 1.00-4.27, p=0.051). The association between mixed breastfeeding and increased HIV transmission risk, together with evidence that exclusive breastfeeding can be successfully supported in HIV-infected women, warrant revision of the present UNICEF, WHO, and UNAIDS infant feeding guidelines.

              Rates, barriers and outcomes of HIV serostatus disclosure among women in developing countries: implications for prevention of mother-to-child transmission programmes.

              This paper synthesizes the rates, barriers, and outcomes of HIV serostatus disclosure among women in developing countries. We identified 17 studies from peer-reviewed journals and international conference abstracts--15 from sub-Saharan Africa and 2 from south-east Asia--that included information on either the rates, barriers or outcomes of HIV serostatus disclosure among women in developing countries. The rates of disclosure reported in these studies ranged from 16.7% to 86%, with women attending free-standing voluntary HIV testing and counselling clinics more likely to disclose their HIV status to their sexual partners than women who were tested in the context of their antenatal care. Barriers to disclosure identified by the women included fear of accusations of infidelity, abandonment, discrimination and violence. Between 3.5% and 14.6% of women reported experiencing a violent reaction from a partner following disclosure. The low rates of HIV serostatus disclosure reported among women in antenatal settings have several implications for prevention of mother-to-child transmission of HIV (pMTCT) programmes as the optimal uptake and adherence to such programmes is difficult for women whose partners are either unaware or not supportive of their participation. This article discusses these implications and offers some strategies for safely increasing the rates of HIV status disclosure among women.
