Systems Analysis Reveals Contraceptive-Induced Alteration of Cervicovaginal Gene Expression in a Randomized Trial. FRONTIERS IN REPRODUCTIVE HEALTH 2022; 4:781687. [PMID: 36303659 PMCID: PMC9580795 DOI: 10.3389/frph.2022.781687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Accepted: 01/31/2022] [Indexed: 12/15/2022] Open
Abstract
Hormonal contraceptives (HCs) are vital in managing the reproductive health of women. However, HC usage has been linked to perturbations in cervicovaginal immunity and increased risk of sexually transmitted infections. Here, we evaluated the impact of three HCs on the cervicovaginal environment using high-throughput transcriptomics. From 2015 to 2017, 130 adolescent females aged 15-19 years were enrolled into a substudy of UChoose, a single-site, open-label randomized, crossover trial (NCT02404038) and randomized to injectable norethisterone-enanthate (Net-En), combined oral contraceptives (COC), or etonorgesterol/ethinyl-estradiol-combined contraceptive vaginal ring (CCVR). Cervicovaginal samples were collected after 16 weeks of randomized HC use and analyzed by RNA-Seq, 16S rRNA gene sequencing, and Luminex analysis. Participants in the CCVR arm had a significant elevation of transcriptional networks driven by IL-6, IL-1, and NFKB, and lower expression of genes supporting epithelial barrier integrity. An integrated multivariate analysis demonstrated that networks of microbial dysbiosis and inflammation best discriminated the CCVR arm from the other contraceptive groups, while genes involved in epithelial cell differentiation were predictive of the Net-En and COC arms. Collectively, these data from a randomized trial represent the most comprehensive "omics" analyses of the cervicovaginal response to HCs and provide important mechanistic guidelines for the provision of HCs in sub-Saharan Africa.

Progestin-based contraception regimens modulate expression of putative HIV risk factors in the vaginal epithelium of pig-tailed Macaques. Am J Reprod Immunol 2018; 80:e13029. [PMID: 30076667 DOI: 10.1111/aji.13029] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2018] [Revised: 06/15/2018] [Accepted: 07/11/2018] [Indexed: 12/30/2022] Open
Abstract
PROBLEM In women, the use of progestin-based contraception may increase the risk of vaginal HIV acquisition. We previously showed in macaques that there is a significantly higher simian-human immunodeficiency virus (SHIV) acquisition rate in the luteal phase of the menstrual cycle, which presents a naturally high-progesterone state, and this may be attributable to altered expression of innate immune factors. We hypothesized that progestin-based contraception, especially depot medroxyprogesterone acetate (DMPA), would, in a similar way, affect mucosal immune factors that influence HIV acquisition risk. METHOD OF STUDY We used a pig-tailed macaque model to evaluate the effects of two progestin-based contraceptives, DMPA, and levonorgestrel (LNG)/ethinyl estradiol (EE)-based combined oral contraceptives (COCs), on innate mucosal factors. We compared the vaginal epithelial thickness data from previous studies and used cytokine profiling and microarray analysis to evaluate contraception-induced molecular changes in the vagina. RESULTS The administration of DMPA caused a reduction in the thickness of the vaginal epithelium relative to that of the follicular or luteal phase. DMPA also induced a significant increase in vaginal levels of the anti-inflammatory cytokine IL-10. Both DMPA- and LNG-based contraception induced a signature of gene expression similar to that of the luteal phase, only more exacerbated, including widespread downregulation of antiviral genes. CONCLUSION The use of progestin-based contraception might engender a milieu that poses an increased risk of HIV acquisition as compared to both the luteal and follicular phases of the menstrual cycle.

Abstract
Access to effective affordable contraception is critical for individual and public health. A wide range of hormonal contraceptives (HCs), which differ in composition, concentration of the progestin component, frequency of dosage, and method of administration, is currently available globally. However, the options are rather limited in settings with restricted economic resources that frequently overlap with areas of high HIV-1 prevalence. The predominant contraceptive used in sub-Saharan Africa is the progestin-only three-monthly injectable depot medroxyprogesterone acetate. Determination of whether HCs affect HIV-1 acquisition has been hampered by behavioral differences potentially confounding clinical observational data. Meta-analysis of these studies shows a significant association between depot medroxyprogesterone acetate use and increased risk of HIV-1 acquisition, raising important concerns. No association was found for combined oral contraceptives containing levonorgestrel, nor for the two-monthly injectable contraceptive norethisterone enanthate, although data for norethisterone enanthate are limited. Susceptibility to HIV-1 and other sexually transmitted infections may, however, be dependent on the type of progestin present in the formulation. Several underlying biological mechanisms that may mediate the effect of HCs on HIV-1 and other sexually transmitted infection acquisition have been identified in clinical, animal, and ex vivo studies. A substantial gap exists in the translation of basic research into clinical practice and public health policy. To bridge this gap, we review the current knowledge of underlying mechanisms and biological effects of commonly used progestins. The review sheds light on issues critical for an informed choice of progestins for the identification of safe, effective, acceptable, and affordable contraceptive methods.

Abstract
BACKGROUND HIV acquisition in the female genital tract remains incompletely understood. Quantitative data on biological HIV risk factors, the influence of reproductive hormones, and infection risk are lacking. We evaluated vaginal epithelial thickness during the menstrual cycle in pigtail macaques (Macaca nemestrina). This model previously revealed increased susceptibility to vaginal infection during and after progesterone-dominated periods in the menstrual cycle. METHODS Nucleated and nonnucleated (superficial) epithelial layers were quantitated throughout the menstrual cycle of 16 macaques. We examined the relationship with previously estimated vaginal SHIVSF162P3 acquisition time points in the cycle of 43 different animals repeatedly exposed to low virus doses. RESULTS In the luteal phase (days 17 to cycle end), the mean vaginal epithelium thinned to 66% of mean follicular thickness (days 1-16; P = 0.007, Mann-Whitney test). Analyzing 4-day segments, the epithelium was thickest on days 9 to 12 and thinned to 31% thereof on days 29 to 32, with reductions of nucleated and nonnucleated layers to 36% and 15% of their previous thickness, respectively. The proportion of animals with estimated SHIV acquisition in each cycle segment correlated with nonnucleated layer thinning (Pearson r = 0.7, P < 0.05, linear regression analysis), but not nucleated layer thinning (Pearson r = 0.6, P = 0.15). CONCLUSIONS These data provide a detailed picture of dynamic cycle-related changes in the vaginal epithelium of pigtail macaques. Substantial thinning occurred in the superficial, nonnucleated layer, which maintains the vaginal microbiome. The findings support vaginal tissue architecture as susceptibility factor for infection and contribute to our understanding of innate resistance to SHIV infection.

A Novel Microbicide/Contraceptive Intravaginal Ring Protects Macaque Genital Mucosa against SHIV-RT Infection Ex Vivo. PLoS One 2016; 11:e0159332.

Abstract
Women need multipurpose prevention products (MPTs) that protect against sexually transmitted infections (STIs) and provide contraception. The Population Council has developed a prototype intravaginal ring (IVR) releasing the non-nucleoside reverse transcriptase inhibitor (NNRTI) MIV-150 (M), zinc acetate (ZA), carrageenan (CG) and levonorgestrel (LNG) (MZCL IVR) to protect against HIV, HSV-2, HPV and unintended pregnancy. Our objective was to evaluate the anti-SHIV-RT activity of MZCL IVR in genital mucosa. First, macaque vaginal tissues were challenged with SHIV-RT in the presence of (i) MIV-150 ± LNG or (ii) vaginal fluids (VF); available from studies completed earlier) collected at various time points post insertion of MZCL and MZC IVRs. Then, (iii) MZCL IVRs (vs. LNG IVRs) were inserted in non-Depo Provera-treated macaques for 24h and VF, genital biopsies, and blood were collected and tissues were challenged with SHIV-RT. Infection was monitored with one step SIV gag qRT-PCR or p27 ELISA. MIV-150 (LCMS/MS, RIA), LNG (RIA) and CG (ELISA) were measured in different compartments. Log-normal generalized mixed linear models were used for analysis. LNG did not affect the anti-SHIV-RT activity of MIV-150 in vitro. MIV-150 in VF from MZC/MZCL IVR-treated macaques inhibited SHIV-RT in vaginal mucosa in a dose-dependent manner (p<0.05). MIV-150 in vaginal tissue from MZCL IVR-treated animals inhibited ex vivo infection relative to baseline (96%; p<0.0001) and post LNG IVR group (90%, p<0.001). No MIV-150 dose-dependent protection was observed, likely because of high MIV-150 concentrations in all vaginal tissue samples. In cervical tissue, MIV-150 inhibited infection vs. baseline (99%; p<0.05). No cervical tissue was available for MIV-150 measurement. Exposure to LNG IVR did not change tissue infection level. These observations support further development of MZCL IVR as a multipurpose prevention technology to improve women's sexual and reproductive health.

Abstract
BACKGROUND Depot-medroxyprogesterone acetate (DMPA) has been associated in some studies with increased HIV susceptibility in women. We used a pigtail macaque model to document the effects of repeated DMPA treatments and their potential contribution to increased SHIV susceptibility. METHODS Nine pigtails were administered 2.5, 1.5, or 0.5 mg/kg DMPA in study weeks one and four. Menstrual cycling, vaginal epithelial thickness, and other SHIV susceptibility factors were monitored for a mean of 24 study weeks. RESULTS All DMPA treatments suppressed menstrual cycling and increased vaginal pH. The vaginal epithelium thinned naturally during baseline menstrual cycles (from mean of 351 to 161 μm in late-luteal phase). Following DMPA, the non-nucleated layer was temporarily absent. Two weeks post-second DMPA injection, mean epithelial thickness was 53, 45, and 167 μm for the descending doses, respectively. CONCLUSIONS All animals showed temporal vaginal epithelial thinning with loss of the non-nucleated layer, and vaginal pH changes post-DMPA injections.
