    Contraception use and HIV outcomes among women initiating dolutegravir-containing antiretroviral therapy in Kenya: a retrospective cohort study
    (Wiley, 2022) Humphrey, John M.; Omodi, Victor; Bernard, Caitlin; Maina, Mercy; Thorne, Julie; Mwangi, Ann; Wools-Kaloustian, Kara; Patel, Rena C.; Medicine, School of Medicine
    Introduction: The rollout of dolutegravir (DTG) in low- and middle-income countries was disrupted by a potential association reported with periconceptional DTG exposure among women living with HIV (WLHIV) and infant neural tube defects. This prompted countries to issue interim guidance limiting DTG use among women of reproductive potential to those on effective contraception. Data to understand the potential impact of such guidance on WLHIV are limited. Methods: We conducted a retrospective cohort analysis of WLHIV 15-49 years initiating DTG-containing antiretroviral treatment (ART) in Kenya from 2017 to 2020. We determined baseline effective (oral, injectable or lactational amenorrhea) and very effective (implant, intrauterine device or female sterilization) contraception use among women who initiated DTG before (Group 1) or during (Group 2) the interim guideline period. We defined incident contraception use in each group as the number of contraceptive methods initiated ≤180 days post-guideline (Group 1) or post-DTG initiation (Group 2). We determined the proportions of all women who switched from DTG- to non-nucleoside reverse transcriptase inhibitor (NNRTI)- (efavirenz or nevirapine) containing ART ≤12 months post-DTG initiation, compared their viral suppression (<1000 copies/ml) and conducted multivariable logistic regression to determine factors associated with switching from DTG to NNRTI-containing ART. Results: Among 5155 WLHIV in the analysis (median age 43 years), 89% initiated DTG after transitioning from an NNRTI. Baseline effective and very effective contraception use, respectively, by the group were: Group 1 (12% and 13%) and Group 2 (41% and 35%). Incident contraception use in each group was <5%. Overall, 498 (10%) women switched from DTG to an NNRTI. Viral suppression among those remaining on DTG versus switched to NNRTI was 95% and 96%, respectively (p = 0.63). In multivariable analysis, incident effective and very effective contraception use was not associated with switching. Conclusions: Baseline, but not incident, effective contraception use was higher during the interim guideline period compared to before it, suggesting women already using effective contraception were preferentially selected to initiate DTG after the guideline was released. These findings reveal challenges in the implementation of policy which ties antiretroviral access to contraceptive use. Future guidance should capture nuances of contraception decision-making and support women's agency to make informed decisions.

    Experiences of sexual and reproductive health screening and counseling in the clinical setting among adolescents and young adults with rheumatic disease
    (Springer Nature, 2025-01-20) Huynh, Brittany; Ott, Mary A.; Tarvin, Stacey E.; Pediatrics, School of Medicine
    Background: Our objective was to describe differences among adolescents and young adults (AYAs) with rheumatic disease using teratogens compared to non-users in receipt of sexual and reproductive health (SRH) counseling, teratogenicity knowledge, perceived importance of SRH topics, and preferences around counseling. Methods: AYAs ages 14-23 years and assigned female at birth were recruited from pediatric rheumatology clinics at a Midwest tertiary care program. Participants completed a one-time online survey assessing SRH. Results: One-hundred eight participants completed the survey, representing a range of rheumatic diseases. 24% reported ever having sex. 36% used a teratogen. Rates of screening and counseling regarding SRH topics were low. Notably, pregnancy prevention and emergency contraception (EC) counseling by rheumatologists were uncommon and not associated with teratogen use or sexual activity. Among AYAs on teratogens, only half reported screening for sexual activity or counseling on teratogenicity or pregnancy prevention. Gaps in pregnancy prevention and EC counseling remained even when accounting for counseling by other providers. Knowledge of medication teratogenicity was also low. AYAs reported SRH topics of high importance, and many reported recent concerns. They preferred to receive information from their rheumatologist, and most agreed it is important to talk to their rheumatologist regarding these topics. Conclusions: AYAs with rheumatic disease report low levels of SRH screening and counseling by their rheumatologist yet report these topics are important and want to discuss them. Gaps in teratogenicity knowledge were identified. This study identifies a need for improved communication with AYAs regarding their SRH.
