Contraceptive/HIV Affecting Risk in Adolescents (CHARA)

February 5, 2019 updated by: Katherine Bunge, University of Pittsburgh
This study will evaluate the impact of hormonal contraceptives on HIV risk associated with changes to the innate immunity in the female genital tract in a cross-sectional study. HIV risk will be evaluated by the capacity of cervical tissue to replicate HIV when challenged ex vivo and correlated to the number of CD4 T cells, DCs, and macrophages; the capacity of cervicovaginal fluid to inhibit HIV will be correlated to soluble mucosal mediators, and the vaginal microbiota. The lower genital tract samples will be collected from 120 adolescents aged 18-19 (40 using no hormonal contraception, 40 using ENG-I, 40 using LNG-IUS). For comparison, 90 adult women aged 25-45 will be equally distributed between the same groupings.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 45 years (ADULT)

Genders Eligible for Study

Sampling Method

Non-Probability Sample

Study Population

non-pregnant, HIV negative, healthy 18-19 year old women and 25-45 year old women

Description

Inclusion Criteria:

  1. Meets one of the following age groups (at the time of sample collection):

    1. Adolescent aged 18-19
    2. Adult aged 25-45

  2. Meets one of the following contraception groups:

    1. Regular menstrual cycles by participant history (if not using hormonal contraception)
    2. Use of ENG-I (i.e. Implanon/Nexplanon) for at least 30 days by participant history
    3. Use of LNG-IUS (Mirena or Skyla) for at least 30 days by participant history
  3. HIV uninfected Note: HIV testing will be done as part of screening. However, if a woman participated in a recent research study and has an HIV test result available from that study, this will suffice provided the date of the test is within 6 months of the study visit.
  4. Willing to undergo pelvic exam and collection of cervical biopsies
  5. Willing to provided written informed consent
  6. Agree to be sexually abstinent for 48 hours prior to the cervical biopsies and for one week after the biopsies.

Exclusion Criteria:

  1. Use of any other hormonal contraception other than ENG-I or LNG-IUS
  2. Use of a diaphragm or spermicide for contraception
  3. Pregnant or pregnancy within 90 days
  4. Currently breastfeeding
  5. Currently menstruating/bleeding (at time of specimen collection) Note: participant can return after cessation of bleeding for specimen collection
  6. Past participation in more than one study involving cervical biopsies per participant report
  7. Cervical biopsies within one month of specimen collection visit
  8. Abnormal vaginal discharge or other genital tract symptoms at the time of specimen collection
  9. Pelvic findings on the day of specimen collection consistent with cervicitis (i.e. MPC, erythema, edema) or anatomy making cervical biopsies difficult
  10. Menopausal
  11. Hysterectomy
  12. History of malignancy of the genital tract (including cervix, uterus, vagina, and vulva)
  13. History of immunosuppression (including HIV infection, diabetes, and chronic steroid use)
  14. Known history of a platelet/bleeding/clotting disorder
  15. Use of a systemic or vaginal antimicrobial agent within 7 days of specimen collection
  16. Use of any vaginal product (i.e. douching, spermicide, lubricant) or device within 7 days of specimen collection Note: tampon use is acceptable
  17. Any other condition that in the opinion of the Study Investigator would preclude provision of informed consent or make study participation unsafe, complicate the interpretation of study outcome data, or otherwise interfere with achieving the study objectives.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
HIV replication in cervical tissue as measured by levels of HIV p24/viral transcripts
Time Frame: baseline
cervical tissue testing
baseline
number of immune cells in cervical tissue, including CD45, CD3, CD4, and CD8 and their expression of CCR5, CCR6 and CD69, and CD11c+ DCs and CD14+ macrophages
Time Frame: baseline
cervical tissue testing
baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Prevalence of bacterial vaginosis defined as a Nugent score ≥7 on a vaginal smear
Time Frame: baseline
vaginal specimen
baseline
prevalence and quantity of lactobacillus species and bacterial vaginosis associated bacteria as measured by traditional culture methods and quantitative PCR
Time Frame: baseline
vaginal specimen
baseline
HIV inhibitory activity in mucosal fluid; and soluble mucosal factors identified through pathway analyses and confirmed by targeted ELISA/multiplexing technology (proteases/ anti-proteases, keratin, IFNε, and other molecules)
