Background The risk of sexual HIV transmission in serodiscordant couples when the HIV-positive partner has full virologic suppression on combination antiretroviral therapy (cART) is debated. This study aims to systematically review observational studies and randomized controlled trials (RCTs), evaluating rates of sexual HIV transmission between heterosexual serodiscordant couples when the HIV-positive partner has full suppression on cART. Methods and Findings We searched major bibliographic databases to November 2012 for relevant observational studies and RCTs without language restrictions. Conference proceedings, key journals and bibliographies were also searched. Studies reporting HIV transmission rates, cART histories and viral loads of the HIV-positive partners were included. Two reviewers extracted methodologic characteristics and outcomes. Of 20,252 citations, 3 studies met all eligibility criteria with confirmed full virologic suppression in the HIV-positive partner. We included 3 additional studies (2 cohort studies, 1 RCT) that did not confirm viral suppression in the HIV-positive partner at transmission in a secondary meta-analysis. Methodologic quality was reasonable. The rate of transmission in the 3 studies confirming virologic suppression was 0 per 100 person-years (95% CI = 0–0.05), with low heterogeneity (I2 = 0%). When we included the 3 studies that did not confirm virologic suppression, the rate of transmission was 0.14 per 100 person-years (95%CI = 0.04–0.31) (I2 = 0%). In a sensitivity analysis including all 6 studies, the rate of transmission was 0 per 100 person-years (95%CI = 0–0.01) after omitting all transmissions with known detectable or unconfirmed viral loads, as full suppression in these cases was unlikely. Limitations included lack of data on same-sex couples, type of sexual intercourse (vaginal vs. anal), direction of HIV transmission, exact viral load at the time of transmission, sexually transmitted infections (STI) rates, and extent of condom use. Conclusions Our findings suggest minimal risk of sexual HIV transmission for heterosexual serodiscordant couples when the HIV-positive partner has full viral suppression on cART with caveats regarding information on sexual intercourse type, STIs, and condom use. These findings have implications when counseling heterosexual serodiscordant couples on sexual and reproductive health. More research is needed to explore HIV transmission risk between same-sex couples.

This study aimed to understand gender and ethnicity differences in HIV-related stigma experienced by 1026 HIV-positive individuals living in Ontario, Canada that were enrolled in the OHTN Cohort Study. Total and subscale HIV-related stigma scores were measured using the revised HIV-related Stigma Scale. Correlates of total stigma scores were assessed in univariate and multivariate linear regression. Women had significantly higher total and subscale stigma scores than men (total, median = 56.0 vs. 48.0, p<0.0001). Among men and women, Black individuals had the highest, Aboriginal and Asian/Latin-American/Unspecified people intermediate, and White individuals the lowest total stigma scores. The gender-ethnicity interaction term was significant in multivariate analysis: Black women and Asian/Latin-American/Unspecified men reported the highest HIV-related stigma scores. Gender and ethnicity differences in HIV-related stigma were identified in our cohort. Findings suggest differing approaches may be required to address HIV-related stigma based on gender and ethnicity; and such strategies should challenge racist and sexist stereotypes.

Background Cohort data examining differences by gender in clinical responses to combination antiretroviral therapy (ART) remain inconsistent and have yet to be explored in a multi-province Canadian setting. This study investigates gender differences by injection drug use (IDU) history in virologic responses to ART and mortality. Methods Data from the Canadian Observational Cohort (CANOC) collaboration, a multisite cohort study of HIV-positive individuals initiating ART after January 1, 2000, were included. This analysis was restricted to participants with a follow-up HIV-RNA plasma viral load measure and known IDU history. Weibull hazard regression evaluated time to virologic suppression (2 consecutive measures <50 copies/mL), rebound (>1000 copies/mL after suppression), and all-cause mortality. Sensitivity analyses explored the impact of presumed ART use in pregnancy on virologic outcomes. Results At baseline, women (1120 of 5442 participants) were younger (median 36 vs. 41 years) and more frequently reported IDU history (43.5% vs. 28.8%) (both p<0.001). Irrespective of IDU history, in adjusted multivariable analyses women were significantly less likely to virologically suppress after ART initiation and were at increased risk of viral load rebound. In adjusted time to death analysis, no differences by gender were noted. After adjusting for presumed ART use in pregnancy, observed gender differences in time to virologic suppression for non-IDU, and time to virologic rebound for IDU, became insignificant. Conclusions HIV-positive women in CANOC are at heightened risk for poor clinical outcomes. Further understanding of the intersections between gender and other factors augmenting risk is needed to maximize the benefits of ART.

A review of reproductive health research, guidelines and related gaps for women living with HIV

Mona Loutfy; Ulrike Sonnenberg-Schwan; Shari Margolese; Lorraine Sherr

The study of pregnancy and motherhood in women living with HIV (WLWH) has concentrated on the health of the unborn baby and the prevention of mother-to-child transmission, whereas consideration of the broader aspects of womens reproductive health has been largely overlooked. The rights of WLWH with respect to their reproductive health should be exactly the same as non-HIV-positive women, however, inequalities exist due to discrimination and also because the treatment guidelines used in the care of women are often based on insufficient evidence. The purpose of this article is to review the available literature on reproductive health issues for WLWH and to identify gaps requiring further investigation. Our review indicates that further research is warranted into a number of aspects of reproductive health among WLWH. Currently, access to the relevant reproductive health resources and services, such as advice on contraception and fertility services, for WLWH is far from optimal in many developed countries and most developing countries. More data are needed on the most appropriate family planning options with the consideration of drug interactions between contraceptives and antiretroviral therapy and the risk of HIV transmission. Also, more research is needed to improve understanding of the maternal health challenges facing WLWH. Similarly, our understanding of the impact of HIV on the physical and emotional health of pregnant women and new mothers is far from complete. Answering these questions and countering these inequalities will help to ensure the reproductive health and child-bearing intentions of WLWH become an integral part of HIV medicine.

HIV stigma is a pressing concern for people living with HIV, and particularly when it is perpetuated by health care providers, as it may affect quality of life and access to health care services. The current study describes the development and initial validation of a contextually appropriate HIV stigma scale for health care providers in North America. A ground-up qualitative approach was used to develop the scale, and it was assessed psychometrically with health care trainees across Canada. The measure demonstrates excellent internal consistency reliability and test–retest reliability, as well as convergent and divergent validity. The study supports a tripartite model of HIV stigma consisting of stereotyping, prejudice and discrimination. The scale provides a new tool to assess HIV stigma in health care providers and can be used to inform training, intervention and self-evaluation of stigmatizing attitudes, beliefs and behaviors among providers.

This study investigates the differences in severity and correlates of depression symptoms among 1069 men and 267 women living with HIV in Ontario, Canada, who completed the 20-item Center for Epidemiologic Studies Depression Scale (CES-D). Women had higher CES-D scores than that of men (median [interquartile range]: 13 [5-26] versus 9 [3-20], P = .0004). More women had total CES-D scores >15 (mild-moderate depression; 44% versus 33%, P = .002) and >21 (severe depression; 31% versus 23%, P = .003). Unlike men, at age 40, women’s scores increased yearly (0.4 per increased year, P = .005). The distribution of scores differed by gender: There was no difference in the 10th percentile of depression scores, 0 (95% confidence interval [CI]: 1.0-1.0) but the 75th percentile of depression scores for women was 6 (95% CI: 2.0-10.0) points higher than that of men. Important gender differences exist in depression symptoms and in correlates of symptoms in people living with HIV.

Decreased mortality, decreased risk of vertical HIV transmission, and many people living with HIV (PLWHIV) being of reproductive age have led many PLWHIV to consider pregnancy. However, scarce data exist regarding the conception planning resources required and available for PLWHIV to have safe and healthy pregnancies. This study aimed to identify gaps between the need for, knowledge of, and access to conception planning information and services among PLWHIV in Ontario, Canada. PLWHIV from three large and two small urban sites in Ontario were recruited (n = 63). Participants completed a cross-sectional survey assessing demographics, expectations and plans for conception, and knowledge about and access to existing conception information and services for PLWHIV. Univariate correlations and ranked analyses were used to assess the associations between the need for, knowledge of, and access to conception planning resources with various demographic variables. Participants’ median age was 40 years (interquartile range = 33–45) with 52% being female, 73% identified as heterosexual, and 27% as lesbian, gay, bisexual, queer, transgender, two-spirited, or other. Univariable analysis indicated that male PLWHIV and those from small urban areas were less likely to expect children in the future and less likely to speak to healthcare providers about conception planning. Although 63% of all participants intended to conceive and 44% had a plan for conception in the near future, only 30% had spoken to a healthcare provider about pregnancy and only 30% had some knowledge about conception planning and assisted reproductive services for safer conception for PLWHIV. Knowledge of and access to resources on conception planning for PLWHIV varied by sexual orientation and geographic location in Ontario. Our results show a gap between the need for conception information and knowledge of and access to adequate information and resources among PLWHIV in Ontario, which may impact the psychosocial well-being of PLWHIV and their children.

The purpose of this cross-sectional study is to assess the desire, need, perceptions, and knowledge of assisted reproductive technologies (ARTs) for women living with HIV (WLWHIV) and determine correlates of ART knowledge desire. WLWHIV of reproductive age were surveyed using the survey instrument “The HIV Pregnancy Planning Questionnaire” at HIV/AIDS service organizations across Ontario, Canada. Of our cohort of 500 WLWHIV, median age was 38, 88% were previously pregnant, 78% desired more information regarding ART, 59% were open to the idea of receiving ART, 39% felt they could access a sperm bank, and 17% had difficulties conceiving (self-reported). Age, African ethnicity, and residence in an urban center were correlated with desire for more ART information. Of participants, 50% wanted to speak to an obstetrician/gynecologist regarding pregnancy planning, and 74% regarded physicians as a main source of fertility service information. While the majority of participants in our cohort desire access to ART information, most do not perceive these services as readily accessible. Healthcare practitioners were viewed as main sources of information regarding fertility services and need to provide accurate information regarding access. Fertility service professionals need to be aware of the increasing demand for ART among WLWHIV.
