Safer conception needs for HIV prevention among female sex workers in Burkina Faso and Togo. Infect Dis Obstet Gynecol 2014; 2014:296245. [PMID: 25404849 PMCID: PMC4227409 DOI: 10.1155/2014/296245] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2014] [Revised: 10/07/2014] [Accepted: 10/08/2014] [Indexed: 11/18/2022] Open
Abstract
Background. Reproductive health programming for female sex workers (FSW) may include contraceptive services but rarely addresses safer pregnancy planning.
Methods. Adult FSW were enrolled into a cross-sectional study across four sites in Burkina Faso and Togo using respondent-driven sampling. Sociobehavioral questionnaires and HIV counseling and testing were administered. Sample statistics and engagement in HIV treatment were described and compared using Chi-squared statistics. Results. 1,349 reproductive-aged FSW were enrolled from January to July 2013. Overall, 267 FSW (19.8%) were currently trying to conceive. FSW trying to conceive were more likely to test positive for HIV at enrollment as compared to women not trying to become pregnant (24.5% versus 17.7%, P < 0.01); however awareness of HIV status was similar across groups. Among FSW trying to conceive, 79.0% (211/267) had previously received HIV testing, yet only 33.8% (23/68) of HIV-infected FSW reported a previous HIV diagnosis. Overall 25.0% (17/68) of HIV-infected FSW trying to conceive were on antiretroviral therapy. Conclusion. FSW frequently desire children. However engagement in the HIV prevention and treatment cascade among FSW trying to conceive is poor potentiating periconception transmission risks to partners and infants. Programs to facilitate earlier HIV diagnosis for FSW and safer conception counseling are needed as components of effective combination HIV prevention services.

Abstract
HIV-affected couples face unique challenges that require access to information and reproductive services to prevent HIV transmission to the uninfected partner and offspring while allowing couples to fulfil their reproductive goals. In regions of high HIV prevalence in sub-Saharan Africa, HIV-affected couples require multipurpose prevention technologies (MPTs) to enhance their reproductive healthcare options beyond contraception and prevention of HIV/sexually transmitted infections (STIs) to include assistance in childbearing. The unique characteristics of the condom and its accepted use in conjunction with safer conception interventions allow HIV-serodiscordant couples an opportunity to maintain reproductive health, prevent HIV/STI transmission, and achieve their reproductive goals while timing conception. Re-thinking the traditional view of the condom and incorporating a broader reproductive health perspective of HIV-affected couples into MPT methodologies will impact demand, acceptability and uptake of these future technologies.

Abstract
Most human immunodeficiency virus (HIV) infections among women occur early in reproductive life, which highlights the importance of understanding the impact of HIV on reproductive functions, and also the potential implications of reproductive function and aging on the course of HIV disease. Ovarian function is a crucial component of reproductive biology in women, but standard assessment methods are of limited applicability to women with chronic diseases such as HIV. Pregnancy can now be achieved without transmission of HIV to sexual partner or newborn, but complications of pregnancy may be more common in women infected with HIV than uninfected women.

High medication adherence during periconception periods among HIV-1-uninfected women participating in a clinical trial of antiretroviral pre-exposure prophylaxis.

[PMID: 25118795 PMCID: PMC4149628 DOI: 10.1097/qai.0000000000000246] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2014] [Accepted: 05/23/2014] [Indexed: 12/30/2022]
Abstract
INTRODUCTION Pre-exposure prophylaxis (PrEP) may be an important safer conception strategy for HIV-1-uninfected women with HIV-1-infected partners. Understanding medication adherence in this population may inform whether PrEP is a feasible safer conception strategy. METHODS We evaluated predictors of pregnancy and adherence to study medication among HIV-1-uninfected women enrolled in a randomized placebo-controlled trial of PrEP among African HIV-1-serodiscordant couples. Participants were counseled on HIV-1 risk reduction, contraception, and adherence and tested for pregnancy at monthly study visits. Pill counts of dispensed drug were performed and, at a subset of visits, plasma was collected to measure active drug concentration. RESULTS Among 1785 women, pregnancy incidence was 10.2 per 100 person-years. Younger age, not using contraception, having an additional sexual partner, and reporting unprotected sex were associated with increased likelihood of pregnancy. Monthly clinic pill counts estimated that women experiencing pregnancy took 97% of prescribed doses overall, with at least 80% pill adherence for 98% of study months, and no difference in adherence in the periconception period compared with previous periods (P = 0.98). Tenofovir was detected in plasma at 71% of visits where pregnancy was discovered. By multiple measures, adherence was similar for women experiencing and not experiencing pregnancy (P ≥ 0.1). CONCLUSIONS In this clinical trial of PrEP, pregnancy incidence was 10% per year despite excellent access to effective contraception. Women experiencing pregnancy had high medication adherence, suggesting that PrEP may be an acceptable and feasible safer conception strategy for HIV-1-uninfected women with HIV-1-serodiscordant partners.

Abstract
We conducted in-depth interviews with a variety of health care providers (n = 33) in Uganda to identify current services that could support and act as barriers to the provision of safer conception counseling (SCC). Consistent with their training and expertise, providers of all types reported provision of services for people living with a diagnosis of HIV or AIDS who desire a child. Important barriers, including a lack of service integration, poor communication between stakeholders, and the absence of policy guidelines, were identified. Drawing on these data, we propose a model of integrated care that includes both SCC services and prevention of unplanned pregnancies.

Abstract
In this qualitative study, researchers assessed knowledge, acceptability, and feasibility of safer conception methods (SCM; timed unprotected intercourse [TUI], manual self-insemination, and sperm washing) among various health care providers (n = 33) and 48 HIV clients with recent or current childbearing intentions in Uganda. While several clients and providers had heard of SCM (especially TUI), few fully understood how to use the methods. All provider types expressed a desire to incorporate SCM into their practice; however, this will require training and counseling protocols, sensitization to overcome cultural norms that pose obstacles to these methods, and partner engagement (particularly by men) in safer conception counseling.

Abstract
OBJECTIVE To describe the development and implementation of a safer conception service in a resource-limited setting. METHODS Qualitative work to inform the design of a safer conception service was conducted with clients and providers at Witkoppen Health and Welfare Centre, a primary health center in Johannesburg, South Africa. Services began in July 2013 for HIV-affected participants planning conception within 6 months and included counseling about timed unprotected intercourse and home-based self-insemination, early initiation of combined antiretroviral therapy (cART) for HIV-infected individuals, pre-exposure prophylaxis for HIV-uninfected partners and circumcision for men. Participants were enrolled into an implementation science study evaluating method uptake, acceptability, and pregnancy and HIV transmission outcomes. RESULTS Findings to-date from 51 qualitative participants and 128 clinical cohort participants (82 women and 46 men, representing 82 partnerships) are presented. All men were accompanied by female partners, whereas 56% of women attended with their male partner. Fifteen of the 46 couples (33%) were in confirmed serodiscordant relationships; however, of the 36 additional women attending alone, 56% were unaware of their partners' HIV status or believed them to be HIV-uninfected. The majority of the HIV-infected women (86%) and men (71%) were on cART at enrollment; however, only 47% on cART were virally suppressed. Timed unprotected intercourse, self-insemination and cART were common choices for participants; few elected pre-exposure prophylaxis. CONCLUSIONS Lessons learned from early implementation demonstrate feasibility of safer conception services; however, reaching discordant couples, cART-naïve infected partners, and men remain challenges. Creating demand for safer conception services among those at highest risk for HIV transmission is necessary.

HIV pre-exposure prophylaxis for people who inject drugs: a review of current results and an agenda for future research. J Int AIDS Soc 2014; 17:18899. [PMID: 24679634 PMCID: PMC3969508 DOI: 10.7448/ias.17.1.18899] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2013] [Revised: 02/03/2014] [Accepted: 02/12/2014] [Indexed: 02/01/2023] Open
Abstract
Introduction Studies examining the use of pre-exposure prophylaxis (PrEP) to prevent HIV transmission among people who inject drugs (PWIDs) have not been adequately summarized. Recently, the Bangkok Tenofovir Study has shown that PrEP may be effective at reducing new HIV infections among this high-risk group. This randomized controlled trial was the first study to specifically examine the efficacy of PrEP among PWIDs. In this review, we present the current state of evidence regarding the use of PrEP to prevent HIV infection in PWID populations, and set an agenda for future research to inform the most effective implementation of PrEP in the context of existing evidence-based HIV prevention strategies. Discussion Despite positive trial results confirming that PrEP may prevent HIV transmission among PWIDs, there remain many questions regarding the interpretation of these results, as well as obstacles to the implementation of PrEP regimens within highly diverse drug-using communities. Aside from the Bangkok Tenofovir Study, we identified only one other published study that has collected empirical data to inform the use of PrEP among PWIDs. The large gap in research regarding the use and implementation of PrEP for PWIDs signals the need for further research and attention. Conclusions We recommend that future research efforts focus on elucidating the generalizability of the Bangkok Tenofovir Study results in other injection drug–using populations, examining the willingness of PWIDs to use PrEP in diverse contexts, identifying barriers to adherence to PrEP regimens and determining the most effective ways to implement PrEP programmes within the context of existing evidence-based prevention strategies, including opioid substitution therapy and needle and syringe distribution programmes.

Abstract
OBJECTIVE To assess the real-world implications of oral tenofovir-emtricitabine (TDF-FTC) for HIV preexposure prophylaxis (PrEP) in clinical practice and highlight important considerations for its implementation. DATA SOURCES A search of PubMed (January 1996 through June 2013) was conducted using the terms HIV preexposure prophylaxis, HIV prevention, tenofovir, and emtricitabine. Abstracts from 2012-2013 HIV/AIDS conferences were also reviewed. STUDY SELECTION AND DATA EXTRACTION All pertinent original studies and review articles published in English were evaluated for inclusion. Reference citations from identified articles were examined for additional content. DATA SYNTHESIS Although antiretroviral therapy has been highly successful in reducing AIDS outcomes and death in HIV-infected patients worldwide, transmission of HIV remains a major global health problem. The recent approval of oral TDF-FTC for HIV PrEP represents the latest biomedical intervention to help control this epidemic. Four published randomized studies evaluated the efficacy and safety of this combination to prevent HIV transmission in several at-risk populations, including men who have sex with men, serodiscordant couples, and heterosexuals residing in endemic regions. Overall, these studies demonstrated significant risk reductions in the incidence of new HIV infections with good short-term tolerability. Despite promising results from clinical studies, several limitations may hinder the utility of PrEP in clinical practice. Most importantly, PrEP was studied in the context of a comprehensive prevention program, including intensive counseling on adherence, high-risk behaviors, and traditional preventative measures. If PrEP is implemented without these adjunct measures, concerns about failure and increased resistance may eventually be realized. CONCLUSION The greatest impact of PrEP, both clinically and financially, will likely arise from judicious application in select high-risk populations. If used appropriately, PrEP has the potential to augment reductions in the current incidence of new HIV infections, and pharmacists will have an important role in the careful selection and counseling of these targeted populations.

Abstract
Improved health outcomes have resulted in people with HIV facing decisions about childbearing. We sought to understand the factors associated with desire for a child among men and women in Malawi. HIV-infected men and women ages 18-40 were invited to participate in a brief interview about fertility desires. Single variable logistic regression was used to evaluate the factors associated with the outcome of fertility desire. Additionally, multiple logistic regression was used to assess the relationship of all the factors together on the outcome of fertility desire. In-depth interviews with women were performed to understand experiences with reproductive health care. A total of 202 brief interviews were completed with 75 men (37.1%) and 127 women (62.9%), with 103 (51.0%) of respondents desiring a child. Being in a relationship (OR: 3.48, 95% CI: 1.58-7.65, p = 0.002) and duration of HIV more than two years (OR: 2.00, 95% CI: 1.08-3.67, p = 0.03) were associated with increased odds of desire for a child. Age 36-40 years (OR: 0.64, 95% CI: 0.46-0.90, p = 0.009) and having a living child (OR: 0.24, 95% CI: 0.07-0.84, p = 0.03) were associated with decreased odds of desire for a child. Seventy percent of women (n = 19 of 27 respondents) completing semistructured interviews who responded to the question about decision-making reported that their male partners made decisions about children, while the remainder reported the decision was collaborative (n = 8, 30%). Eighty-six percent of women (n = 36 of 42 respondents) reported no discussion or a discouraging discussion with a provider about having children. HIV-infected women and men in Malawi maintain a desire to have children. Interventions are needed to integrate safer conception into HIV care, to improve male participation in safer conception counseling, and to empower providers to help patients make decisions about reproduction free of discrimination and coercion.

Abstract
Globally, research has documented high fertility desires and intentions among HIV-positive women. Improving implementation of preconception care (PCC) for people living with HIV is critical, given estimates that the majority of HIV-positive women who want future biological children have not received reproductive counseling, largely due to a lack of provider-initiated conversations. This article offers initial recommendations and outlines key considerations for a research agenda to advance PCC implementation efforts in both high-resource and low-resource settings. We consider who should provide PCC; where it can be effectively delivered; when it should be offered; and two potential implementation models depending on available resources. We conclude with a call for PCC-specific implementation science and research translation to help people living with HIV achieve their reproductive goals.

Abstract
Objective Many people living with HIV in sub-Saharan Africa desire biological children. Implementation of HIV prevention strategies that support the reproductive goals of people living with HIV while minimizing HIV transmission risk to sexual partners and future children requires a comprehensive understanding of pregnancy in this population. We analyzed prospective cohort data to determine pregnancy incidence and predictors among HIV-positive women initiating antiretroviral therapy (ART) in a setting with high HIV prevalence and fertility. Methods Participants were enrolled in the Uganda AIDS Rural Treatment Outcomes (UARTO) cohort of HIV-positive individuals initiating ART in Mbarara. Bloodwork (including CD4 cells/mm3, HIV viral load) and questionnaires (including socio-demographics, health status, sexual behavior, partner dynamics, HIV history, and self-reported pregnancy) were completed at baseline and quarterly. Our analysis includes 351 HIV-positive women (18–49 years) who enrolled between 2005–2011. We measured pregnancy incidence by proximal and distal time relative to ART initiation and used multivariable Cox proportional hazards regression analysis (with repeated events) to identify baseline and time-dependent predictors of pregnancy post-ART initiation. Results At baseline (pre-ART initiation), median age was 33 years [IQR: 27–37] and median prior livebirths was four [IQR: 2–6]. 38% were married with 61% reporting HIV-positive spouses. 73% of women had disclosed HIV status to a primary sexual partner. Median baseline CD4 was 137 cells/mm3 [IQR: 81–207]. At enrolment, 9.1% (31/342) reported current pregnancy. After ART initiation, 84 women experienced 105 pregnancies over 3.8 median years of follow-up, yielding a pregnancy incidence of 9.40 per 100 WYs. Three years post-ART initiation, cumulative probability of at least one pregnancy was 28% and independently associated with younger age (Adjusted Hazard Ratio (AHR): 0.89/year increase; 95%CI: 0.86–0.92) and HIV serostatus disclosure to primary sexual partner (AHR: 2.45; 95%CI: 1.29–4.63). Conclusions Nearly one-third of women became pregnant within three years of initiating ART, highlighting the need for integrated services to prevent unintended pregnancies and reduce periconception-related risks for HIV-infected women choosing to conceive. Association with younger age and disclosure suggests a role for early and couples-based safer conception counselling.

Abstract
Objectives Using cohort data nested in a randomized trial conducted in Cameroon, this study aimed to investigate time trends and predictors of the susceptibility to transmitting HIV during the first 24 months of treatment. Methods The outcome, susceptibility to transmitting HIV, was defined as reporting inconsistent condom use and experiencing incomplete virological suppression. Mixed logistic regressions were performed to identify predictors of this outcome among 250 patients reporting to have had sexual relationships either with HIV-negative or unknown HIV status partner(s). Results Despite an initial decrease from 76% at M0 to 50% at M6, the rate of inconsistent condom use significantly increased from M12 (59%) to M24 (66%) (p = 0.017). However, the proportion of patients susceptible to transmitting HIV significantly decreased over follow-up from 76% at M0, to 50% at M6, 31% at M12 and 27% at M24 (p<0.001). After controlling for age, gender and intervention group, we found that perceiving healthcare staff’s readiness to listen as poor (adjusted odds ratios (AOR) [95% Confidence Interval (CI)] = 1.87 [1.01–3.46]), reporting to have sexual relationships more than once per week (AOR [95%CI] = 2.52 [1.29–4.93]), having more than one sexual partner (AOR [95%CI] = 2.53 [1.21–5.30]) and desiring a/another child (AOR [95%CI] = 2.07 [1.10–3.87]) were all associated with a higher risk of being susceptible to transmitting HIV. Conversely, time since ART initiation (AOR [95%CI] = 0.66 [0.53–0.83] for an extra 6 months and ART adherence (AOR [95%CI] = 0.33 [0.15–0.72]) were significantly associated with a lower risk of being susceptible to transmitting HIV. Conclusions The decrease observed in the susceptibility to transmitting HIV suggests that fear of behavioural disinhibition should not be a barrier to universal access to ART. However, developing adequate preventive interventions matching patients’ expectations -like the desire to have children- and strengthening healthcare staff’s counselling skills are urgently needed to maximize the impact of ART in slowing the HIV epidemic.

Abstract
Background Antiretroviral prophylaxis may be a critical strategy to reduce periconception HIV transmission. Maximizing the benefit of periconception pharmacologic HIV risk-reduction requires an understanding of the links between pregnancy and adherence to this prevention strategy. Methods We assessed study gel adherence among women with pregnancies compared to women without pregnancies enrolled in the CAPRISA 004 phase IIB trial of 1% vaginal tenofovir gel. Pregnancy was assessed with monthly urine tests. Adherence was measured monthly and defined as proportion of sex acts covered by two returned, used applicators based on pre- and post-coital dosing. High adherence was defined as a median adherence score of >80%, that is, more than 80% of sex acts were covered by two applications of study gel. A multivariate generalized estimating equations (GEE) model with a binomial distribution was used to assess covariates associated with high adherence (>80%) over time. Median adherence before and after pregnancy was compared using Wilcoxon signed rank test. Results Among 868 women, 53 had at least 1 pregnancy (4.06 per 100 woman years, 95% CI: 3.04, 5.31). Women with pregnancies had lower median adherence compared to women without pregnancies (50% [IQR: 45–83] vs. 60% [IQR: 50–100], p = 0.02). Women with pregnancies also had a 48% lower odds of high adherence compared to women without pregnancies when adjusting for confounders (aOR 0.52, 95%CI: 0.41–0.66, p<0.0001). Among women with pregnancies, adherence before and after pregnancy was not different (50% [IQR: 46–83] vs. 55% [IQR: 20–100], p = 0.68). Conclusions Women with pregnancies were less likely to have high adherence to study gel compared to women without pregnancies. Understanding these differences may inform findings from HIV prevention trials and future implementation of antiretroviral prophylaxis for at-risk women who choose to conceive. The protocol for the parent trial is registered on ClinicalTrials.gov, NCT00441298, http://www.clinicaltrials.gov/ct2/show/NCT00441298.
