Welcome to I-TECH HIV/AIDS Clinical Seminar Series 3rd June 2010 Contraception in the Setting of HIV R. Scott McClelland, MD, MPH Outline • • • • Brief ‘world view’ of contraception and HIV What are the benefits of contraception? Contraception in the setting of HIV Clinical case studies in contraception – Safety – Efficacy – Side effects – Management in different clinical scenarios Learning Objectives • Be able to provide HIV-positive women with a clear explanation of the potential benefits and risks of different contraceptive choices • Feel comfortable with basic clinical decision making for initiation and continuation of contraception in HIV-positive women Global Use of Contraception • ~800 million women use modern methods of contraception – ~150 million use hormonal contraceptives – Others use intra-uterine contraceptive devices, barriers, and tubal ligation Unmet Contraceptive Need Ref: Network Vol 23, number 3, 2004. Family Health International Benefits of Contraception in the Setting of HIV • Contraception reduces pregnancy and may provide additional health, social, and economic benefits. – Groups should discuss briefly, then rank top three benefits of contraception. Consider both general benefits and specific advantages of contraception in the setting of HIV. Benefits of Contraception • Avoid unplanned pregnancies – Potential for obstetrical complications – Spacing pregnancies benefits the health of women, infants, and children • Family planning empowers women, reducing gender inequality • HIV-positive women may wish to reduce risk of vertical transmission by preventing further pregnancies Case 1 • 24 y.o. HIV+ woman presents for 6 week postpartum visit. She initiated ART during pregnancy with CD4=226. She would like to avoid another pregnancy. – Can she be offered hormonal contraception? Many Women Living with HIV Remain Sexually Active • Abstinence eliminates sexual transmission risk, but often not possible or desired by women or partners • Dual protection minimizes HIV/STI transmission risk and lowers risk of pregnancy Case 1 • 24 y.o. HIV+ woman presents for 6 week postpartum visit. She initiated ART during pregnancy with CD4=226. She would like to avoid another pregnancy. – Will contraception influence the risk of HIV progression? Hormonal Contraception and HIV Progression • Secondary analysis from 1 RCT suggests increased disease progression with HC compared to intrauterine device (IUD)1 • 7 prospective cohort studies suggest HC in chronic HIV doesn’t significantly change CD4, plasma viral load, or mortality2,3 1. Stringer et al. AIDS 2009; 23: 1377-82 2. Curtis et al. AIDS 2009; 23 Supplement 1:S55-S67 3. Polis et al. CROI 2010, San Francisco, Feb 2010, abstract 152 Hormonal Contraception vs. IUD in HIV+ Women • • • • 599 postpartum women in Lusaka, Zambia RCT IUD vs. hormonal contraception Followed for at least 2 years Primary endpoint: Safety and efficacy of intrauterine device vs. hormonal contraception • Secondary endpoints: – Time to CD4<200 – Time to death – Combined endpoint including either time to CD4<200 or death Stringer AJOG 2007:197:144.e1-144.e8 Hormonal Contraception vs. IUD in HIV+ Women • Only one episode of PID in IUD arm • Higher rate of discontinuation in IUD arm • Pregnancy higher in HC vs. IUD – HR 2.2 (95% CI 1.2-2.4) • Mortality did not differ significantly – HR 1.4 (95% CI 0.7-3.0) • Faster progression to CD4<200 with hormonal contraception compared to IUD – HR 1.6 (95% CI 1.04-2.03) Hormonal Contraception vs. IUD in HIV+ Women CD4 decline Death Hormonal Contraception vs. IUD in HIV+ Women CD4 decline Death CD4 decline or death •Time to CD4<200 or death faster in HC vs. IUD • HR 1.6 (95% CI 1.1-2.3) Study Summary: Hormonal Contraception vs. IUD in HIV+ Women • IUD appeared safe and was more effective than HC at preventing pregnancy • No difference in mortality • Time to CD4<200 longer with IUD vs. HC • Limitations – ~30% withdrew or lost to follow-up – ~30% discontinued allocated method – Postnatal population; can we generalize to other women? Hormonal Contraception in HIV+ Women • 319 post-partum women in Nairobi1 – No effect on CD4 or plasma VL to 24 months in Depo-Provera or OCP compared to no HC • US Women’s Interagency HIV Study2 – Plasma VL not influenced by HC – Small increase in CD4 over long-term follow-up • 213 women initiating HC in Mombasa3 – No increase in plasma VL over 2 months 1. Richardson AIDS 2007; 21:749-53 2. Cejtin AIDS 2003;17:1702-4 3. Wang AIDS 2004;18:205-9 Hormonal Contraception and Time to AIDS or Death: Rakai, Uganda • 625 women followed from HIV acquisition • Use of HC associated with lower risk of AIDS/death aHR (0.70, 95%CI 0.50-0.97) – Effect appeared to be present only after median time to AIDS/death (4.4 years) – Compared to women using non-hormonal contraception, HC users had similar risk of progression Polis et al. CROI 2010, San Francisco, Feb 2010, Abstract 152 Hormonal Contraception and HIV Progression • Majority of evidence (from cohort studies) suggests that initiating HC in HIV+ women does not increase disease progression – One RCT suggested increased progression, but with several important limitations Case 2 • 27 y.o. woman reports sex work and has been screened periodically for HIV with multiple prior negative tests. Uses Depo-Provera to prevent pregnancy. She now has a positive HIV test. – Will Depo-Provera use at the time of HIV acquisition influence the natural history of her HIV infection? http://www.street-papers.org/eastern-asia/ Hormonal Contraception and HIV Progression • Effect may differ depending on the timing of hormonal contraception in relation to HIV-1 acquisition – Hormonal contraception initiation during chronic HIV infection (e.g. Case 1) – Hormonal contraception at the time of HIV acquisition (e.g. Case 2) Depo-Provera at Time of HIV Acquisition • Indirect evidence from surrogate endpoints – Women using DMPA at the time of HIV acquisition have • Higher set-point plasma viral load • Greater viral diversity at infection • Viral diversity is associated with more rapid CD4 decline Sagar et al. J Virol 2003; 77:12921-12926 Sagar M et al. AIDS 2004;18:615-619. Hormonal Contraception and HIV Progression • Majority of evidence (from cohort studies) suggests that initiating HC in HIV+ women does not increase disease progression – One RCT suggested increased progression, but with several important limitations • HC at time of infection may influence diversity of the infecting viral population, set point VL, and rate of CD4 decline – Unknown effect on morbidity and mortality Case 3 • 30 y.o.
