RESUMEN

The Human Research Council's National HIV Prevalence, Incidence and Behavior Survey ranks South Africa first in HIV incidence in the world with 400,000 new infections in 2012 and found the HIV incidence rate among female youth aged 15 to 24 years to be 2.5% that year. The objective of this study was to compare the pattern and predictability of sexual activity between HIV-infected and HIV-uninfected young South African women. Sexually active young women between the ages of 16 and 21 years old completed a study survey between October 2012 and 2014 at two Desmond Tutu HIV Foundation centers. 100 young women with a mean age of 19.04 years responded to the survey. 51 women (51%) were HIV-infected and 49 were HIV-uninfected (49%). HIV-infected young women were found to be statistically less likely to have a temporal pattern to their sexual activity as compared to HIV-uninfected young women (56.9 vs. 95.9%, p<0.0001). While controlling for frequency of sex and lifetime sexual partners, HIV status remains a significant predictor of having a pattern of sexual activity (OR=16.13, p=0.0004) and a predictor of having sex on the weekend only (OR=4.41, p=0.0022). The ability to predict when sexual activity will occur enables a woman to prepare for its associated risks. HIV-uninfected young women are more likely to have a predictable pattern to their sexual activity as compared to HIV-infected young women. Knowledge of the sexual behavior patterns of this high-risk population will aid in the development of effective HIV prevention campaigns.

RESUMEN

In high prevalence environments relationship characteristics are likely to be associated with HIV risk, yet evidence indicates general underestimation of risk. Furthermore uncertainty about partner's risk may challenge PrEP demand among young African women. We conducted quantitative and qualitative interviews with women before and after HIV discussions with partners, to explore how partner's behavior affected risk perceptions and interest in PrEP. Twenty-three women were interviewed once; twelve had a follow-up interview after speaking to their partners. Fourteen women were willing to have their partner contacted; yet two men participated. Several themes related to relationships and risk were identified. These highlighted that young women's romantic feelings and expectations influenced their perceptions of risk within their relationships, consistent with the concept of motivated reasoning. Findings emphasize challenges in using risk to promote HIV prevention among young women. Framing PrEP in a positive empowering way that avoids linking it to relationship risk may ultimately encourage greater uptake.

RESUMEN

Women of reproductive age account for nearly half of all HIV-infected people worldwide. Childbearing intention among HIV-infected women is complicated by social and reproductive concerns related to their HIV status. We conducted a cross-sectional study of HIV-infected and HIV-uninfected sexually active South African women aged 17 to 21 in order to compare their childbearing intentions and to identify predictors of the desire to have children among women with HIV. We found the rate of childbearing intention to be similarly high among both HIV-infected and HIV-uninfected study participants (80 and 79% respectively, p=0.81). History of previous parity was found to be associated with decreased intention to have children. No difference in childbearing intention was found between HIV-infected women on anti-retroviral therapy (ART) and women not on ART. High rates of childbearing intention among HIV-infected women require integration of reproductive health services with comprehensive HIV/AIDS care in order to mitigate the risks of sexual and vertical transmission of HIV.

RESUMEN

Infection with HIV is known to increase the risk of cervical cancer. In addition, evidence suggests that concurrent infection with multiple human papillomavirus (HPV) genotypes increases the risk of cervical dysplasia more than infection with a single HPV genotype. However, the impact of the combination of HIV coinfection and presence of multiple concurrent HPV infections on the risk of cervical dysplasia is uncertain. We compared the results of HPV testing and Pap smears between HIV-infected and HIV-uninfected young women to assess the cumulative impact of these two conditions. We found that both HIV and the presence of multiple concurrent HPV infections are associated with increased risk of associated Pap smear abnormality and that the impact of these two risk factors may be additive.

RESUMEN

OBJECTIVES: In VOICE, a phase IIB trial of daily oral and vaginal tenofovir for HIV prevention, at least 50% of women receiving active products had undetectable tenofovir in all plasma samples tested. MTN-003D, an ancillary study using in-depth interviews (IDIs) and focus group discussions (FGDs), together with retrospective disclosure of plasma tenofovir pharmacokinetic results, explored adherence challenges during VOICE. METHODS: We systematically recruited participants with pharmacokinetic data (median six plasma samples), categorized as low (0%, N = 79), inconsistent (1-74%, N = 28) or high (≥75%; N = 20) on the basis of frequency of tenofovir detection. Following disclosure of pharmacokinetic results, reactions were captured and adherence challenges systematically elicited; IDIs and FGDs were audio-recorded, transcribed, coded and thematically analysed. RESULTS: We interviewed 127 participants from South Africa, Uganda and Zimbabwe. The most common reactions to pharmacokinetic results included surprise (41%; low pharmacokinetic), acceptance (39%; inconsistent pharmacokinetic) and happiness (65%; high pharmacokinetic). On the basis of participants' explanations, we developed a typology of adherence patterns: noninitiation, discontinuation, misimplementation (resulting from visit-driven use, variable taking, modified dosing or regimen) and adherence. Fear of product side effects/harm was a frequent concern, fuelled by stories shared among participants. Although women with high pharmacokinetic levels reported similar concerns, several described strategies to overcome challenges. Women at all pharmacokinetic levels suggested real-time drug monitoring and feedback to improve adherence and reporting. CONCLUSION: Retrospective provision of pharmacokinetic results seemingly promoted candid discussions around nonadherence and study participation. The effect of real-time drug monitoring and feedback on adherence and accuracy of reporting should be evaluated in trials.

RESUMEN

OBJECTIVES: Persistence of infection with high-risk Human papillomaviruses (HR-HPV) increases the risk of incident and progressive precancerous lesions of the cervix. Rates of HR-HPV persistence have been shown to be increased among HIV-infected adult women, however there is a paucity of literature addressing HPV persistence in the young HIV-infected population. We compared rates of HR-HPV persistence between HIV-infected and HIV-uninfected young women. METHODS: We obtained self-collected vaginal swabs at six-month intervals from 50 HIV-uninfected and 33 HIV-infected young women recruited through a community youth center (age 17-21 years) and compared rates of HR-HPV persistence. HR-HPV testing was conducted using the Roche's Linear Array® HPV Test. RESULTS: Eighty-three prevalent (upon baseline testing) and incident (upon subsequent testing) individual HR-HPV infections were identified among 43 members of the cohort (23 HIV-uninfected and 20 HIV-infected). At twelve months, 19% of baseline HR-HPV infections continued to be present with a statistically significant difference between HIV-uninfected and HIV-infected participants (4% versus 31%; p=0.01). CONCLUSIONS: HIV-infected young women in our cohort had a seven-fold increased rate of persistence of HR-HPV overall at 12 months, indicating an increased risk for incident and progressive precancerous lesions. Identification of persistent infection with HR-HPV may complement cytological findings in determining the need for colposcopy.

RESUMEN

OBJECTIVE: The aim of this study is to examine the knowledge of human papillomavirus (HPV) and cervical cancer among HIV-infected and HIV-uninfected female adolescents in South Africa. METHODS: Subjects were recruited from a parent study of HPV infection comprised of females ages 16-21 in Masiphumelele, Cape Town, South Africa. A total of 30 subjects, 15 HIV-infected and 15 HIV-uninfected, were selected via randomization and completed a measure of HPV knowledge, based on a previously validated instrument. The study took place in May 2013. RESULTS: The overall mean score on the measure for all subjects was 43.3% (S.D. 10.9). There was no significant difference in HPV knowledge between the HIV-infected and HIV-uninfected groups. Based on results from a previous large-scale study using the same validated measure, this sample scored significantly worse on general HPV knowledge than samples from the US, UK, and Australia. CONCLUSION: Given the limited knowledge of HPV in this sample, there is greater need for education about the prevention of cervical cancer, specifically among high-risk adolescent women.

RESUMEN

BACKGROUND: HIV-infected adolescents may be at higher risk for high-grade cervical lesions than HIV-uninfected adolescents. The purpose of this study was to compare the prevalence of high-risk HPV (HR-HPV) infections and Pap smear abnormalities between these two groups. METHODS: In this cross-sectional study, we compared the HPV DNA and Pap smear results between 35 HIV-infected and 50 HIV-uninfected adolescents in order to determine the prevalence of HR-HPV genotypes and cervical cytological abnormalities. Comparisons were made using Pearson χ (2) and independent-samples t-tests analyses, and associations between demographic and behavioral characteristics and HPV infections were examined. RESULTS: HIV-infected participants were more likely to be infected with any HPV (88.6% versus 48.0%; P < 0.001) and with at least one HR-HPV (60.0% versus 24.0%; P = 0.001), and to have multiple concurrent HPV infections (68.6% versus 22.0%; P < 0.001). HPV 16 and 18 were relatively underrepresented among HR-HPV infections. Abnormal Pap test results were more common among HIV-infected participants (28.8% versus 12.0%; P = 0.054). A history of smoking was associated with HR-HPV infection. CONCLUSIONS: HIV-infected adolescents have an increased risk of infection with HR-HPV and of Pap test abnormalities. The majority of HR-HPV infections among our participants would not be prevented by the currently available vaccinations against HPV.

RESUMEN

Bacterial vaginosis (BV) is a widely prevalent infection that is associated with a range of adverse outcomes. We compared the rates of incidentally identified BV and other cervico-vaginal infections on Papanicolaou (Pap) smears of HIV-infected and HIV-uninfected adolescent females in South Africa. Cervical specimens from 50 HIV-uninfected and 32 HIV-infected sexually active South African adolescent females age 17-21 were collected and analyzed in accordance with the Bethesda system. We found a high overall prevalence of BV (54.9%) in our cohort. While previous research has found an increased prevalence of BV among HIV-infected women, the difference in the prevalence of BV between our HIV-infected group (62.5%) and HIV-uninfected group (50.0%) was not found to be statistically significant. The high rate of BV in both of these groups has significant implications for their risk of HIV acquisition and/or transmission in addition to other associated risks of BV. Given that the Pap smear is specific in incidentally diagnosing BV, it may be utilized as a screening method for BV in the adolescent population.

RESUMEN

The high prevalence of HIV among young people in African countries underscores a pressing need for effective prevention interventions. Adapting school-based prevention programs developed in the United States for use in African schools may present an alternative to the time-consuming process of developing home-grown programs. The researchers report the results of a pretest-posttest field trial of an alcohol/HIV prevention curriculum adapted from an American model and delivered to ninth-grade students in five South African township schools. The revised intervention was based primarily on the Project Northland alcohol prevention and Reducing the Risk safer sex programs. The researchers found significant differences in change from baseline to follow-up between students in intervention and comparison groups on intentions to use a condom; drinking before or during sex; and, among females, sex refusal self-efficacy. The results of the field trial suggest that behavioral interventions developed in Western countries may be rapidly adapted to work in other cultural contexts.
