Abstract
BACKGROUND We explored the role of genital abnormalities and hormonal contraception in human immunodeficiency virus (HIV) transmission among heterosexual serodifferent couples in Rwanda. METHODS From 2002 to 2011, HIV-serodifferent couples who were not using antiretroviral treatment were followed up, and sociodemographic and clinical data were collected, family planning provided, and HIV-negative partners retested. Couples were assessed for genital ulcers; nonulcerative genital sexually transmitted infection (STIs), including gonorrhea, chlamydia, and trichomoniasis; and non-STI vaginal infections, including bacterial vaginosis and candida. Multivariable models evaluated associations between covariates and HIV transmission genetically linked to the index partner. RESULTS Among 877 couples in which the man was HIV positive, 37 linked transmissions occurred. Factors associated with women's HIV acquisition included genital ulceration in the female partner (adjusted hazard ratio, 14.1) and nonulcerative STI in the male partner (8.6). Among 955 couples in which the woman was HIV positive, 46 linked transmissions occurred. Factors associated with HIV acquisition in men included nonulcerative STI in the female partner (adjusted hazard ratio, 4.4), non-STI vaginal dysbiosis (7.1), and genital ulceration in the male partner (2.6). Hormonal contraception use was not associated with HIV transmission or acquisition. CONCLUSIONS Our findings underscore the need for integrating HIV services with care for genital abnormalities. Barriers (eg, cost of training, demand creation, advocacy, and client education; provider time; and clinic space) to joint HIV/STI testing need to be considered and addressed.

Uptake of long acting reversible contraception following integrated couples HIV and fertility goal-based family planning counselling in Catholic and non-Catholic, urban and rural government health centers in Kigali, Rwanda. Reprod Health 2020; 17:126. [PMID: 32807177 PMCID: PMC7433361 DOI: 10.1186/s12978-020-00981-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2019] [Accepted: 08/11/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND When integrated with couples' voluntary HIV counselling and testing (CVCT), family planning including long acting reversible contraceptives (LARC) addresses prongs one and two of prevention of mother-to-child transmission (PMTCT). METHODS In this observational study, we enrolled equal numbers of HIV concordant and discordant couples in four rural and four urban clinics, with two Catholic and two non-Catholic clinics in each area. Eligible couples were fertile, not already using a LARC method, and wished to limit or delay fertility for at least 2 years. We provided CVCT and fertility goal-based family planning counselling with the offer of LARC and conducted multivariate analysis of clinic, couple, and individual predictors of LARC uptake. RESULTS Of 1290 couples enrolled, 960 (74%) selected LARC: Jadelle 5-year implant (37%), Implanon 3-year implant (26%), or copper intrauterine device (IUD) (11%). Uptake was higher in non-Catholic clinics (85% vs. 63% in Catholic clinics, p < 0.0001), in urban clinics (82% vs. 67% in rural clinics, p < 0.0001), and in HIV concordant couples (79% vs. 70% of discordant couples, p = .0005). Religion of the couple was unrelated to clinic religious affiliation, and uptake was highest among Catholics (80%) and lowest among Protestants (70%) who were predominantly Pentecostal. In multivariable analysis, urban location and non-Catholic clinic affiliation, Catholic religion of woman or couple, younger age of men, lower educational level of both partners, non-use of condoms or injectable contraception at enrollment, prior discussion of LARC by the couple, and women not having concerns about negative side effects of implant were associated with LARC uptake. CONCLUSIONS Fertility goal-based LARC recommendations combined with couples' HIV counselling and testing resulted in a high uptake of LARC methods, even among discordant couples using condoms for HIV prevention, in Catholic clinics, and in rural populations. This model successfully integrates prevention of HIV and unplanned pregnancy.

Abstract
Sexually transmitted infections (STIs) in women caused by Chlamydia trachomatis (CT) and/or Neisseria gonorrhoeae (NG) are epidemiologically distinct. In this study, associations with sociodemographic and clinical risk factors are explored separately for CT and NG. Multivariate logistic regression (MLR) models quantify associations between potential CT and/or NG risk factors within a cross-sectional study of high-risk women in two Zambian cities, Lusaka and Ndola. CT was associated with living in Lusaka, younger age, and literacy. Long-acting reversible contraception (LARC) was predictive of CT in Ndola, but protective in Lusaka. In Lusaka only, CT was associated with lower education and reported unprotected sex. NG was associated with younger age, lower education, concurrent Trichomonas vaginalis, bacterial vaginosis, and incident syphilis infection. Signs and symptoms were rare and not associated with either infection. CT was more prevalent, nearly 11%, compared to NG, 6.8%. The higher prevalence of CT could explain the lack of association with other STIs. The associations observed with NG could be the result of high-risk sexual networks or lack of protective immunity. Risk factors for CT and NG are distinct and may differ geographically, which should be considered when developing diagnostic tools or guiding presumptive treatment in specific populations.

Motivational interviewing to promote long-acting reversible contraception among Rwandan couples wishing to prevent or delay pregnancy. Am J Obstet Gynecol 2020; 222:S919.e1-S919.e12. [PMID: 31838122 DOI: 10.1016/j.ajog.2019.11.1280] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2019] [Revised: 11/19/2019] [Accepted: 11/27/2019] [Indexed: 10/25/2022]
Abstract
BACKGROUND Few family-planning programs in Africa base demand creation and service delivery on theoretical models. Motivational interviewing is a counseling modality that facilitates reflection on the benefits and disadvantages of a health outcome to encourage behavior change. OBJECTIVES We evaluate a couples-focused joint family-planning and HIV counseling intervention using motivational interviewing to enhance uptake of long-acting reversible contraception (Paragard copper intrauterine device or Jadelle hormonal implant) among Rwandan couples. STUDY DESIGN In this experimental study, couples receiving care at 8 government health clinics in Kigali, the capital city, were referred from a parent study of couples who did not want more children or wanted to wait at least 2 years for their next pregnancy. Long-acting reversible contraception methods were offered on site following joint HIV testing and family-planning counseling. At the first follow-up visit 1 month after enrollment in the parent study, couples who had not yet chosen a long-acting reversible contraception method were interviewed separately using motivational interviewing and then brought together and again offered long-acting reversible contraception. RESULTS Following motivational interviewing, 78 of 229 couples (34%) requested a long-acting reversible contraception method (68 implant and 10 intrauterine device). Long-acting reversible contraception uptake after motivational interviewing was associated with the woman being Catholic (vs Protestant/Muslim/other, adjusted odds ratio, 2.87, 95% confidence interval, 1.19-6.96, P = .019) or having an income (vs no income, adjusted odds ratio, 2.54, 95% confidence interval, 1.12-5.73, P = .025); the couple having previously discussed long-acting reversible contraception (adjusted odds ratio, 8.38, 95% confidence interval, 2.54-27.59, P = .0005); either partner believing that unplanned pregnancy was likely with their current method (adjusted odds ratio, 6.67, 95% confidence interval, 2.77-16.11, P < .0001); or that they might forget to take or make an appointment for their current method (adjusted odds ratio, 4.04, 95% confidence interval, 1.32-12.34, P = .014). Neither partner mentioning that condoms also prevent HIV/sexually transmitted infection was associated with long-acting reversible contraception uptake (adjusted odds ratio, 2.86, 95% confidence interval, 1.17-7.03, P = .022), as was the woman citing long-term duration of action of the implant as an advantage (adjusted odds ratio, 5.41, 95% confidence interval, 1.86-15.76, P = .002). The woman not listing any side effects or disadvantages of implants was associated with long-acting reversible contraception uptake (adjusted odds ratio, 5.42, 95% confidence interval, 2.33-12.59, P < .0001). Clinic location (rural vs urban), couple HIV status, and concerns about negative economic effects of an unplanned pregnancy were significant in bivariate but not multivariate analysis. CONCLUSION Encouraging couples to reflect on the benefits and disadvantages of long-acting reversible contraception methods, the likelihood of unplanned pregnancy with their current contraception, and the impact of an unplanned pregnancy is an effective motivational interviewing technique in family-planning counseling. One third of couples who did not want a pregnancy for at least 2 years but had not chosen a long-acting reversible contraception method when provided with standard family-planning counseling did so after motivational interviewing. Involving the male partner in family-planning discussions facilitates joint decision making about fertility goals and contraceptive choice. Combining family planning and joint HIV testing for couples allows targeted focus on dual-method use with discordant couples, who are advised to use condoms for HIV/sexually transmitted infection prevention along with a more effective contraceptive for added protection against unplanned pregnancy.

Abstract
OBJECTIVE To examine the relationship between hormonal contraception and vaginal infections with bacterial vaginosis, vaginal candidiasis, or trichomoniasis. METHODS Couples who were human immunodeficiency virus (HIV) serodiscordant in Zambia were enrolled in a longitudinal cohort study. From 1994 to 2002, both partners were seen quarterly and received physical exams including genital examinations. Separate rates for three outcome infections of interest (bacterial vaginosis, vaginal candidiasis, and trichomoniasis) were calculated. Bivariate associations between baseline and time-varying covariates and outcome infections of interest were evaluated using unadjusted Anderson-Gill survival models. Adjusted hazard ratios (aHRs) were generated using multivariable Anderson-Gill survival models that included demographic and clinical factors associated with both hormonal contraceptive use and each infection of interest. RESULTS There were 1,558 cases of bacterial vaginosis, 1,529 cases of vaginal candidiasis, and 574 cases of trichomoniasis over 2,143 person-years of observation. Depot medroxyprogesterone acetate (DMPA) users had significantly lower rates of trichomoniasis and bacterial vaginosis. In adjusted models, DMPA was protective for bacterial vaginosis (aHR=0.72; 95% CI 0.54-0.95), candidiasis (aHR 0.75, 95% CI 0.57-1.00) and trichomoniasis (aHR=0.43, 95% CI 0.25-0.74). Oral contraceptive pills were protective for candidiasis (aHR=0.79, 95% CI 0.65-0.97). CONCLUSION We confirm that DMPA use was associated with reduced rates of the three most common causes of vaginitis, and oral contraceptive pill use was associated with reduced rates of candidiasis among women in couples who were HIV discordant.

Abstract
BACKGROUND We coordinated community health worker (CHW) promotions with training and support of government clinic nurses to increase uptake of long-acting reversible contraception (LARC), specifically the copper intrauterine device (IUD) and the hormonal implant, in Kigali, Rwanda. METHODS From August 2015 to September 2016, CHW provided fertility goal-based family planning counseling focused on LARC methods, engaged couples in family planning counseling, and provided written referrals to clients expressing interest in LARC methods. Simultaneously, we provided didactic and practical training to clinic nurses on LARC insertion and removal. We evaluated: 1) aggregate pre- versus post-implementation LARC uptake as a function of CHW promotions, and 2) demographic factors associated with LARC uptake among women responding to CHW referrals. RESULTS 7712 referrals were delivered by 184 CHW affiliated with eight government clinics resulting in 6072 family planning clinic visits (79% referral uptake). 95% of clinic visits resulted in LARC uptake (16% copper IUD, 79% hormonal implant). The monthly average for IUD insertions doubled from 29 prior to service implementation to 61 after (p < 0.0001), and the monthly average for implant insertions increased from 109 to 309 (p < 0.0001). In adjusted analyses, LARC uptake was associated (p < 0.05) with the CHW referral being issued to the couple (versus the woman alone, adjusted odds ratio, aOR = 2.6), having more children (aOR = 1.3), desiring more children (aOR = 0.8), and having a religious affiliation (aOR = 2.9 Protestant, aOR = 3.1 Catholic, aOR = 2.5 Muslim each versus none/other). Implant versus non-LARC uptake was associated with having little or no education; meanwhile, having higher education was associated with IUD versus implant uptake. CONCLUSIONS Fertility goal-based and couple-focused family planning counseling delivered by CHW, coupled with LARC training and support of nursing staff, substantially increased uptake of LARC methods.

Abstract
Objective: To examine bacterial vaginosis as an effect modifier for the association between hormonal contraception and incident HIV infection. Design: Serodiscordant couples enrolled in an open longitudinal cohort in Lusaka, Zambia from 1994 to 2012. This analysis was restricted to couples with an HIV-positive man enrolled between1994 and 2002 when a quarterly genital tract examination and HIV testing was performed. Methods: Multivariate Cox models evaluated the association between contraceptive method and HIV-acquisition, stratified by time-varying bacterial vaginosis status. Results: Among 564 couples contributing 1137.2 couple-years of observation, bacterial vaginosis was detected at 15.5% of study visits. Twenty-two of 106 seroconversions occurred during intervals after bacterial vaginosis was detected [12 on no method/nonhormonal method (nonhormonal contraception), two on injectables, eight on oral contraceptive pills (OCPs)]. Unadjusted seroincidence rates per 100 couple-years for nonhormonal contraception, injectable, and OCP users, respectively, during intervals with bacterial vaginosis were 8.3, 20.8, and 31.0 and during intervals without bacterial vaginosis were 8.2, 9.7, and 12.3. In the bacterial vaginosis-positive model, there was a significant increase in incident HIV among those using injectables (adjusted hazard ratio, aHR 6.55, 95% CI 1.14–37.77) and OCPs (aHR 5.20, 95% CI 1.68–16.06) compared with nonhormonal contraception. Hormonal contraception did not increase the hazard of HIV acquisition in bacterial vaginosis-negative models. These findings persisted in sensitivity analyses whenever all covariates from the nonstratified model previously published were included, whenever other genital tract findings were excluded from the model and with the addition of condom-less sex and sperm on wet-prep. Conclusion: Future research should consider a potential interaction with bacterial vaginosis whenever evaluating the impact of hormonal contraception on HIV acquisition.

Abstract
Depot medroxyprogesterone acetate (Depo-Provera) has been associated with an increased risk of HIV acquisition. In a longitudinal study, we investigated the impact of Depo-Provera use by healthy women on expression of immune markers for HIV preference and on HIV infection ex vivo at baseline (visit 1), one month (visit 2) and three months (visit 3) after Depo-Provera treatment. We found a significant increase in the frequency and expression of integrin α4β7 on CD4+ T cells at visit 2. Interestingly, Hispanic but not black women exhibited a significant increase in integrin α4β7 cell numbers and expression levels at visit 2, whereas, black but not Hispanic women exhibited a significant change in CCR5 and CD38 expression levels between visit 2 and visit 3. The frequency of terminal effector memory CD4+ T cells decreased significantly in black women from visit 1 to visit 3. Virus production following ex vivo HIV infection of PBMCs was increased at visit 3 compared to visit 1. In black women, the frequency of HIV p24+CD4+ T cells was higher at visit 3 than at visit 1. Expression of integrin α4β7 on HIV p24+CD4+ T cells following ex vivo infection at visit 2 was significantly less than at visit 1. These results demonstrate that Depo-Provera alters the immune profile of peripheral CD4+ T cells and increases susceptibility to HIV infection ex vivo. The observation that these effects differed between women of different ethnicities has implications for developing effective and targeted strategies for HIV prevention.

Abstract
BACKGROUND Dual method use, which combines condoms with a more effective modern contraceptive to optimize prevention of HIV and unplanned pregnancy, is underutilized in high-risk heterosexual couples. MATERIALS AND METHODS Heterosexual HIV-discordant Zambian couples were enrolled from couples' voluntary HIV counseling and testing services into an open cohort with 3-monthly follow-up (1994-2012). Relative to dual method use, defined as consistent condom use plus modern contraception, we examine predictors of (1) condom-only use (suboptimal pregnancy prevention) or (2) modern contraceptive use with inconsistent condom use (effective pregnancy prevention and suboptimal HIV prevention). RESULTS Among 3,049 couples, dual method use occurred in 28% of intervals in M+F- and 23% in M-F+, p < 0.01; condom-only use in 56% in M+F- and 61% in M-F+, p < 0.01; and modern contraceptive use with inconsistent condom use in 16% regardless of serostatus. Predictors (p < 0.05) of condom-only use included the man being HIV+ (adjusted hazard ratio, aHR = 1.15); baseline oral contraceptive pill (aHR = 0.76), injectable (aHR = 0.48), or implant (aHR = 0.60) use; woman's age (aHR = 1.04 per 5 years) and lifetime number of sex partners (aHR = 1.01); postpartum periods (aHR = 1.25); and HIV stage of the index partner III/IV versus I (aHR = 1.10). Predictors (p < 0.05) of modern contraceptive use with inconsistent condom use included woman's age (aHR = 0.94 per 5 years) and HIV+ male circumcision (aHR = 1.51), while time-varying implant use was associated with more consistent condom use (aHR = 0.80). CONCLUSIONS Three-quarters of follow-up intervals did not include dual method use. This highlights the need for counseling to reduce unintended pregnancy and HIV transmission and enable safer conception.

Sustained effect of couples' HIV counselling and testing on risk reduction among Zambian HIV serodiscordant couples. Sex Transm Infect 2017; 93:259-266. [PMID: 28082662 PMCID: PMC5520263 DOI: 10.1136/sextrans-2016-052743] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2016] [Revised: 11/23/2016] [Accepted: 12/21/2016] [Indexed: 01/26/2023] Open
Abstract
Background We present temporal trends in self-reported and biological markers of unprotected sex and sex with concurrent partners in discordant couples receiving couples' voluntary HIV counselling and testing (CVCT). Methods Heterosexual Zambian HIV-serodiscordant couples were enrolled into longitudinal follow-up in an open cohort (1994–2012). Multivariable Anderson-Gill models explored predictors of self-report and biological indicators of unprotected sex within (including sperm on a vaginal swab, incident pregnancy or incident linked HIV infection) and outside (including self-report, STI and unlinked HIV infection) the union. Measures of secular trends in baseline measures were also examined. Results At enrolment of 3049 couples, men were 35 years old on average, women were 29 years, and couples had been together for an average of 7 years. M+F− couples reported an average of 16.6 unprotected sex acts in the 3 months prior to enrolment (pre-CVCT), dropping to 5.3 in the >0–3 month interval, and 2.0 in >6 month intervals (p-trend <0.001). Corresponding values for M−F+ couples were 22.4 unprotected sex acts in the 3 months prior enrolment, dropping to 5.2 in the >0–3 month interval, and 3.1 in >6 month intervals (p-trend <0.001). Significant reductions in self-report and biological markers of outside partners were also noted. Predictors of unprotected sex between study partners after CVCT included prevalent pregnancy (adjusted HR, aHR=1.6–1.9); HIV+ men being circumcised (aHR=1.2); and HIV− women reporting sex with outside partners (aHR=1.3), alcohol (aHR=1.2), injectable (aHR=1.4) or oral (aHR=1.4) contraception use. Fertility intentions were also predictive of unprotected sex (aHR=1.2–1.4). Secular trends indicated steady declines in reported outside partners and STIs. Conclusion Reductions in self-reported unprotected sex after CVCT were substantial and sustained. Reinforced risk-reduction counselling in pregnant couples, couples desiring children and couples with HIV− women having outside partners or using alcohol or injectable or oral contraception are indicated.
