Integrated reproductive health services for people living with HIV must address their fertility intentions. For HIV-serodiscordant couples who want to conceive, attempted conception confers a substantial risk of HIV transmission to the uninfected partner. Behavioral and pharmacologic strategies may reduce HIV transmission risk among HIV-serodiscordant couples who seek to conceive. In order to develop effective pharmaco-behavioral programs, it is important to understand and address the contexts surrounding reproductive decision-making; perceived periconception HIV transmission risk; and periconception risk behaviors. We present a conceptual framework to describe the dynamics involved in periconception HIV risk behaviors in a South African setting. We adapt the Information-Motivation-Behavioral Skill Model of HIV Preventative Behavior to address the structural, individual and couple-level determinants of safer conception behavior. The framework is intended to identify factors that influence periconception HIV risk behavior among serodiscordant couples, and therefore to guide design and implementation of integrated and effective HIV, reproductive health and family planning services that support reproductive decision-making.

BackgroundFollow up of Human Immunodeficiency Virus (HIV)-exposed infants is an important component of Prevention of Mother-to-Child Transmission (PMTCT) programmes in order to ascertain infant outcomes post delivery. We determined HIV transmission, mortality and loss to follow-up (LTFU) of HIV-exposed infants attending a postnatal clinic in an urban hospital in Durban, South Africa.MethodsWe conducted a retrospective cohort study of infants born to women in the PMTCT programme at McCord Hospital, where mothers paid a fee for service. Data were abstracted from patient records for live-born infants delivered between 1 May 2008 and 31 May 2009. The infants’ LTFU status and age was based on the date of the last visit. HIV transmission was calculated as a proportion of infants followed and tested at six weeks. Mortality rates were analyzed using Kaplan-Meier (K-M), with censoring on 15 January 2010, LTFU or death.ResultsOf 260 infants, 155 (59.6%) remained in care at McCord beyond 28 weeks: one died at < 28 days, three died between one to six months; 34 were LTFU within seven days, 60 were LTFU by six months. K-M mortality rate: 1.7% at six months (95% confidence interval (CI): 0.6% to 4.3%). Of 220 (83%) infants tested for HIV at six weeks, six (2.7%, 95% CI: 1.1% to 5.8%) were HIV-infected. In Cox regression analysis, late antenatal attendance (≥ 28 weeks gestation) relative to attending in the first trimester was a predictor for infant LTFU (adjusted hazards ratio = 2.3; 95% CI: 1.0 to 5.1; p = 0.044).ConclusionThis urban PMTCT programme achieved low transmission rates at six weeks, but LTFU in the first six months limited our ability to examine HIV transmission up to 18 months and determinants of mortality. The LTFU of infants born to women who attended antenatal care at 28 weeks gestation or later emphasizes the need to identify late antenatal attendees for follow up care to educate and support them regarding the importance of follow up care for themselves and their infants.

Challenges with couples, serodiscordance and HIV disclosure: healthcare provider perspectives on delivering safer conception services for HIV-affected couples, South Africa

Tamaryn Crankshaw; Deborah Mindry; Chantal Munthree; Thabo Letsoalo; Pranitha Maharaj

Introduction Safer conception interventions should ideally involve both members of an HIV‐affected couple. With serodiscordant couples, healthcare providers will need to manage periconception risk behaviour as well tailor safer conception strategies according to available resources and the HIV status of each partner. Prior to widespread implementation of safer conception services, it is crucial to better understand provider perspectives regarding provision of care since they will be pivotal to the successful delivery of safer conception. This paper reports on findings from a qualitative study exploring the viewpoints and experiences of doctors, nurses, and lay counsellors on safer conception care in a rural and in an urban setting in Durban, South Africa.

Background. Understanding HIV-infected patient experiences and perceptions of reproductive counseling in the health care context is critical to inform design of effective pharmaco-behavioral interventions that minimize periconception HIV risk and support HIV-affected couples to realize their fertility goals. Methods. We conducted semistructured, in-depth interviews with 30 HIV-infected women (with pregnancy in prior year) and 20 HIV-infected men, all reporting serodiscordant partners and accessing care in Durban, South Africa. We investigated patient-reported experiences with safer conception counseling from health care workers (HCWs). Interview transcripts were reviewed and coded using content analysis for conceptual categories and emergent themes. Results. The study findings indicate that HIV-infected patients recognize HCWs as a resource for periconception-related information and are receptive to speaking to a HCW prior to becoming pregnant, but seldom seek or receive conception advice in the clinic setting. HIV nondisclosure and unplanned pregnancy are important intervening factors. When advice is shared, patients reported receiving a range of information. Male participants showed particular interest in accessing safer conception information. Conclusions. HIV-infected men and women with serodiscordant partners are receptive to the idea of safer conception counseling. HCWs need to be supported to routinely initiate accurate safer conception counseling with HIV-infected patients of reproductive age.

South Africa was the largest recipient of funding from the Presidents Emergency Plan for AIDS Relief (PEPFAR) for antiretroviral therapy (ART) programs from 2004 to 2012. Funding decreases have led to transfers from hospital and non-governmental organization-based care to government-funded, community-based clinics. We conducted semi-structured interviews with 36 participants to assess patient experiences related to transfer of care from a PEPFAR-funded, hospital-based clinic in Durban to either primary care clinics or hospital-based clinics. Participant narratives revealed the importance of connectedness between patients and the PEPFAR-funded clinic program staff, who were described as respectful and conscientious. Participants reported that transfer clinics were largely focused on dispensing medication and on throughput, rather than holistic care. Although participants appreciated the free treatment at transfer sites, they expressed frustration with long waiting times and low perceived quality of patient–provider communication, and felt that they were treated disrespectfully. These factors eroded confidence in the quality of the care. The transfer was described by participants as hurried with an apparent lack of preparation at transfer clinics for new patient influx. Formal (e.g., counseling) and informal (e.g., family) social supports, both within and beyond the PEPFAR-funded clinic, provided a buffer to challenges faced during and after the transition in care. These data support the importance of social support, adequate preparation for transfer, and improving the quality of care in receiving clinics, in order to optimize retention in care and long-term adherence to treatment.

The surveillance of HIV‐related cancers in South Africa is hampered by the lack of systematic collection of cancer diagnoses in HIV cohorts and the absence of HIV status in cancer registries. To improve cancer ascertainment and estimate cancer incidence, we linked records of adults (aged ≥ 16 years) on antiretroviral treatment (ART) enrolled at Sinikithemba HIV clinic, McCord Hospital in KwaZulu‐Natal (KZN) with the cancer records of public laboratories in KZN province using probabilistic record linkage (PRL) methods. We calculated incidence rates for all cancers, Kaposi sarcoma (KS), cervix, non‐Hodgkins lymphoma and non‐AIDS defining cancers (NADCs) before and after inclusion of linkage‐identified cancers with 95% confidence intervals (CIs). A total of 8,721 records of HIV‐positive patients were linked with 35,536 cancer records. Between 2004 and 2010, we identified 448 cancers, 82% (n = 367) were recorded in the cancer registry only, 10% (n = 43) in the HIV cohort only and 8% (n = 38) both in the HIV cohort and the cancer registry. The overall cancer incidence rate in patients starting ART increased from 134 (95% CI 91–212) to 877 (95% CI 744–1,041) per 100,000 person‐years after inclusion of linkage‐identified cancers. Incidence rates were highest for KS (432, 95% CI 341–555), followed by cervix (259, 95% CI 179–390) and NADCs (294, 95% CI 223–395) per 100,000 person‐years. Ascertainment of cancer in HIV cohorts is incomplete, PRL is both feasible and essential for cancer ascertainment.

Background A growing number of young people (ages 10–24) are living with HIV (YPLWH) in sub-Saharan Africa (SSA). These YPLWH have particular needs and challenges related to their sexual and reproductive health and rights (SRHR). Contextual factors including gender inequalities, violence, stigma, and discrimination and lack of tailored services undermine YPLWHs SRHR. Objective Understand the scope and impact of interventions targeting YPLWH to improve SRH-related outcomes in SSA. Design We undertook a review to synthesise evaluated interventions (qualitative, quantitative, or mixed methods) aimed at improving the SRH outcomes of YPLWH in SSA with outcomes based on a World Health Organization framework of comprehensive SRHR approaches for women living with HIV. Using inclusion criteria, only six interventions were identified. Results Interventions sought to improve a range of direct and indirect SRH outcomes, including sexual behaviour, adherence, disclosure, and mental health. Four overarching issues emerged: 1) all interventions were structured according to cognitive behavioural therapy theories of behaviour change – while showing promise they do not tackle the wider gender, social, and economic contexts that shape YPLWHs SRH; 2) ‘significant others’ were included in two of the interventions, but further work needs to consider how to leverage parental/guardian support appropriately; 3) interventions only accessed young people who were already linked to care, participants were likely to have better SRH outcomes than those potentially more vulnerable YPLWH; and 4) none of the interventions explored the sexuality of young people. Conclusions There have been a limited number of evaluated interventions to strengthen SRH of YPLWH in SSA, and gaps exist in addressing the SRHR needs of YPLWH. Intervention approaches require greater scope and depth, including the need to address structural and contextual challenges.

Placing contraception at the centre of the HIV prevention agenda.

Tamaryn Crankshaw; Jennifer A. Smit; Mags Beksinska

Over the past decade, the global response to the HIV epidemic has been unprecedented, and enormous progress has been made. Significant investment in the roll out of antiretroviral treatment (ART) and efforts to increase treatment coverage have greatly reduced the number of AIDS-related deaths worldwide. There are a growing number of promising innovations to expand the HIV prevention mix. However, the reach of these interventions is still very limited in adolescent girls and young women (15–24 years) and the full realisation of the intervention mandates has not yet been achieved. The HIV prevention field has been criticised for the tendency to adopt a narrow focus. The Fast-Track Strategy offers a unique opportunity for the HIV prevention field to broaden its gaze and to begin to identify synergies (and efficiencies) with prevention approaches from other global development priorities, namely sexual and reproductive health and rights (SRHR). This paper applies a SRHR lens to HIV prevention by highlighting the critical relationship between unintended pregnancy and HIV, and seeks to expand on earlier debates that prevention of HIV and prevention of unintended pregnancy are inextricably linked, complementary activities with interrelated and common goals. We call for the prioritisation of prevention of unintended pregnancy amongst two overlapping population groups — girls and young women (15–24 years old) and women living with HIV — as a key tactic to accomplish the Joint United Nations Programme on HIV/AIDS (UNAIDS) Fast-Track Strategy and as a way to fully realise existing HIV prevention efforts. We discuss the intersecting pathways between HIV prevention and unintended pregnancy prevention and build a case for contraception to be placed at the centre of the HIV prevention agenda.

OBJECTIVE(S) The childbearing needs of people living with HIV (PLHIV) and the experiences of healthcare providers serving them are explored. We examine provider and client knowledge and views on safer conception methods. METHODS The study uses exploratory qualitative research to understand provider and client perspectives on childbearing and safer conception. Interviews were conducted at 3 sites (1 rural, 2 urban) in eThekwini District, KwaZulu-Natal, South Africa between May 2011 and August 2012, including in-depth interviews with 43 PLHIV, 2 focus group discussions and 12 in-depth interviews with providers. RESULTS Clients had little knowledge and providers had limited knowledge of safer conception methods. While clients were eager to receive counseling on safer conception, providers had some hesitations but were eager to receive training in delivering safer conception services. Clients and providers noted that biological parentage is a major concern of PLHIV. Clients were willing to use any of the described methods to have biological children but some expressed concerns about potential risks associated with timed unprotected intercourse. Male clients required access to reproductive health information. CONCLUSIONS Providers need to routinely initiate discussions with clients about childbearing intentions. Providers need to be enabled with approved guidelines and training to support client access to safer conception methods.

Intimate partner violence (IPV) experienced by pregnant and post-partum women has negative health effects for women, as well as the foetus, and the new-born child. In this study we sought to assess the prevalence and factors associated with recent IPV amongst post-partum women in one clinic in eThekwini Municipality, South Africa, and explore the relationship between IPV, depression and functional limitations/disabilities. Past 12 month IPV-victimisation was 10.55%. Logistic regression modelled relationships between IPV, functional limitations, depressive symptoms, socio-economic measures, and sexual relationship power. In logistic regression models, overall severity of functional limitations were not associated with IPV-victimisation when treated as a continuous overall score. In this model relationship power (aOR0.22, p = 0.001) and depressive symptoms (aOR1.26, p = 0.001) were significant. When the different functional limitations were separated out in a second model, significant factors were relationship power (aOR0.20, p = 0.001), depressive symptoms (aOR1.20, p = 0.011) and mobility limitations (aOR2.96, p = 0.024). The study emphasises that not all functional limitations are associated with IPV-experience, that depression and disability while overlapping can also be considered different drivers of vulnerability, and that women’s experience of IPV is not dependent on pregnancy specific factors, but rather wider social factors that all women experience.
