Integration of reproductive health and rights

Editor’s notes: Integration of reproductive health services and rights needs to be well coordinated with HIV services, so a randomized trial of integration of family planning services into HIV care clinics in Kenya by Cohen CR and colleagues is encouraging.  In their initial randomized trial, 12 clinics were randomly selected for early integration using resources from the study team, while six were delayed.  Subsequently the Ministry of Health took over the integration and provision of “one stop shop” services at all 18 clinics.  The improvements in contraceptive uptake and decreased pregnancy rates that had been observed in the first phase were maintained during the second phase giving more confidence that it was truly the integrated nature of the services rather than the presence of special study team that had led to the difference.

Another major push for integration or coordination between HIV and sexual and reproductive health and rights services is around the prevention of cervical cancer.  Cervical cancer is caused by long-term infection with specific types of human papilloma virus.  Women living with HIV are at considerably increased risk of cervical cancer compared to their HIV-negative peers.  A large cohort study by Kelly HA et al. in Burkina Faso and South Africa has shown that women living with HIV, attending clinical care services have a high prevalence (59-79% at baseline), incidence (48%) and persistence (up to 70% for some types) of HR-HPV and correspondingly a high prevalence and incidence of cervical neoplasia. There are two HPV vaccines currently available, the first prevents HPV types 16 and 18 (the causes of around 70% of cervical cancer) while the newer (and currently more expensive) vaccine prevents nine types (that cause at least 90% of cervical cancer).  HPV vaccination is recommended to be given before sexual debut, as it gives high protection against the specific types of HPV prior to acquisition.  The dynamics of the many different types of HPV after acquisition is less clear.  The virus is often acquired and they may be cleared or may persist.  So this study provides important background data for understanding the possible role of vaccination and also which types are most associated with pre-cancers (cervical Intra-epithelial neoplasia [CIN]) that can be treated and cured relatively easily.  In particular, in this study, HPV58, which is in the same (alpha-9) family as HPV16 showed the greatest association with CIN2+.  HPV58 is included in the newer nonavalent vaccine, but not the current bi- or quadrivalent vaccine.  Overall this is an area where we need more research on the impact of vaccination and screening programmes for women living with HIV, but in the meantime, HPV vaccination for school girls (and boys) is an investment in the future, since these vaccines are effective ways to stop people dying of cervical (and other HPV-related) cancers.

One of the challenges for integrated reproductive services is to continue to emphasize the importance of condoms for protection against HIV and sexually transmitted infections even if other methods are being used for contraception.  Such “dual protection” is particularly hard to achieve in married or cohabiting couples despite evidence of ongoing risk of HIV infection.  A study in 2388 urban 18-24 year old individuals in Zambia (69% female; 35% married) shows that condom use is still much too low with only 45% reporting that they had used a condom in the last 12 months. As might be anticipated, the study found that the poorest and people who were married were least likely to use condoms while people who discussed contraception and agreed to use condoms were more likely to do so [Pinchoff J et al.] The importance of dual protection, and of promoting broader HIV prevention messages to women through integrated (or at least coordinated) reproductive health and rights services is made even more important given the possibility that depot medroxyprogesterone acetate (DMPA) as a long acting reversible contraceptive may increase the risk of HIV acquisition.  WHO has recently changed their guidance to make such contraceptives grade 2 in the Medical Eligibility for Contraceptives (MEC) guidelines.

Objectives: To determine if integration of family planning (FP) and HIV services led to increased use of more effective contraception (i.e. hormonal and permanent methods, and intrauterine devices) and decreased pregnancy rates.

Design: Cohort analysis following cluster randomized trial, when the Kenya Ministry of Health led integration of the remaining control (delayed integration) sites and oversaw integrated services at the original intervention (early integration) sites.

Setting: Eighteen health facilities in Kenya.

Subjects: Women aged 18-45 receiving care: 5682 encounters at baseline, and 11 628 encounters during the fourth quarter of year 2.

Intervention: "One-stop shop" approach to integrating FP and HIV services.

Main outcome measures: Use of more effective contraceptive methods and incident pregnancy across two years of follow-up.

Results: Following integration of FP and HIV services at the six delayed integration clinics, use of more effective contraception increased from 31.7% to 44.2% of encounters (+12.5%; Prevalence ratio (PR) = 1.39 (1.19-1.63). Among the twelve early integration sites, the proportion of encounters at which women used more effective contraceptive methods was sustained from the end of the first to the second year of follow-up (37.5% vs. 37.0%). Pregnancy incidence including all 18 integrated sites in year two declined in comparison to the control arm in year one (rate ratio: 0.72; 95% CI 0.60-0.87).

Conclusions: Integration of FP services into HIV clinics led to a sustained increase in the use of more effective contraceptives and decrease in pregnancy incidence 24 months following implementation of the integrated service model.

Associations of human papillomavirus (HPV) genotypes with high-grade cervical neoplasia (CIN2+) in a cohort of women living with HIV in Burkina Faso and South Africa.

Kelly HA, Ngou J, Chikandiwa A, Sawadogo B, Gilham C, Omar T, Lompo O, Doutre S), Meda N, Weiss HA, Delany-Moretlwe S, Segondy M, Mayaud P; HARP Study Group. PLoS One. 2017 Mar 23;12(3):e0174117. doi: 10.1371/journal.pone.0174117.eCollection 2017.

Objective: To describe associations of high-risk human papillomavirus (HR-HPV) with high-grade cervical intraepithelial neoplasia (CIN2+) in women living with HIV (WLHIV) in Burkina Faso (BF) and South Africa (SA).

Methods: Prospective cohort of WLHIV attending HIV outpatient clinics and treatment centres. Recruitment was stratified by ART status. Cervical HPV genotyping using INNO-LiPA and histological assessment of 4-quadrant cervical biopsies at enrolment and 16 months later.

Results: Among women with CIN2+ at baseline, the prevalence of any HR-HPV genotypes included in the bi/quadrivalent (HPV16/18) or nonavalent (HPV16/18/31/35/45/52/58) HPV vaccines ranged from 37% to 90%. HPV58 was most strongly associated with CIN2+ (aOR = 5.40, 95%CI: 2.77-10.53). At 16-months follow-up, persistence of any HR-HPV was strongly associated with incident CIN2+ (aOR = 7.90, 95%CI: 3.11-20.07), as was persistence of HPV16/18 (aOR = 5.25,95%CI: 2.14-12.91) and the additional HR types in the nonavalent vaccine (aOR =3.23, 95%CI: 1.23-8.54).

Conclusion: HR-HPV persistence is very common among African WLHIV and is linked to incident CIN2+. HPV vaccines could prevent between 37-90% of CIN2+ among African WLHIV.

Why don't urban youth in Zambia use condoms? The influence of gender and marriage on non-use of male condoms among young adults.

Pinchoff J, Boyer CB, Mutombo N, Chowdhuri RN, Ngo TD. PLoS One. 2017 Mar 23;12(3):e0172062. doi: 10.1371/journal.pone.0172062.eCollection 2017.

Background: Zambia experiences high unmet need for family planning and high rates of HIV, particularly among youth. While male condoms are widely available and 95%of adults have heard of them, self-reported use in the past 12 months is low among young adults (45%). This study describes factors associated with non-use of male condoms among urban young adults in Zambia.

Methods: A household cross-sectional survey in four urban districts was conducted from November 2015 to January 2016 among sexually active young adults ages 18-24 years. A random walk strategy was implemented in urban areas; eligible, enrolled participants were administered a survey on household characteristics, health access, and knowledge, attitudes and practices related to contraception. Relative risk regression models were built to determine factors associated with the decision to not use a male condom (non-use) at most recent sexual intercourse.

Results: A total of 2388 individuals were interviewed; 69% were female, 35% were married, and average lifetime sex partners was 3.45 (SD±6.15). Non-use of male condoms was 59% at most recent sexual intercourse. In a multivariate model, women were more likely to report non-use of a male condom compared with men (aRR = 1.24[95% CI: 1.11, 1.38]), married individuals were more likely to report non-use compared with unmarried individuals (aRR = 1.59 [1.46, 1.73]), and those residing in the highest poverty wards were more likely to report non-use compared with those in the lowest poverty wards (aRR = 1.31 [1.16, 1.48]). Those with more negative perceptions of male condom use were 6% more likely to report non-use (aRR = 1.06 [1.03, 1.09]). Discussion regarding contraception with a partner decreased non-use 13% (aRR = 0.87 [0.80, 0.95]) and agreement regarding male condom use with a partner decreased non-use 16% (aRR = 0.84 [0.77, 0.91)]).

Discussion: Non-use of male condoms is high among young, married adults, particularly women, who may be interested in contraception for family planning but remain at risk of STI infection. Effective marketing strategy of dual protection methods to this population is critical.
