  2. Background • In Argentina, transgender (TG) women are a highly vulnerable population • Life expectancy  35 years (vs. 79 in biological women) • Estimated HIV prevalence 34% (vs. 0.4% in the general population) • Argentina´s policies are promoting gender equity • 2007: Right to self-perceived gender identity in healthcare (Buenos Aires) • 2010: Same-sex Marriage Law • 2012: Gender Identity Law • Little is known about engagement in HIV care among TG women Argentina MoH, 2013

  3. Objectives • To characterize engagement in the HIV continuum of care among TG women enrolled in a public HIV clinic in Buenos Aires, Argentina • To explore factors associated with virological suppression within the first year of HIV diagnosis

  4. Methods I • Design • Retrospective clinical chart review • Study population • TG women newly diagnosed with HIV and starting care in Hospital Fernández (HF) (linked to HIV care) between 2000-2012 • Definitions: HIV care cascade indicators • Engaged in HIV care: ≥ 2 HIV-related visits at least 3 months apart within the first year of HIV diagnosis • Retained in HIV care at 1 year: 1 HIV-related visit and/or diagnostic tests at 12 ± 3 months of HIV diagnosis • On ART: ART initiation within the first year of HIV diagnosis • Virologically suppressed: VL <50 copies/mL at 12 ± 3 months of HIV diagnosis US DHHS, Health Resources and Services Administration Institute of Medicine, 2012

  5. Methods II • Data analysis • Percentages at each step of the HIV care cascade within the first year of HIV diagnosis • Bi- and multivariable logistic regression analyses to investigate factors associated with virological suppression at 12 months of HIV diagnosis

  6. Baseline characteristics of TG women enrolled in HF between 2000-12 N= 69 * Denominators for each variable may differ due to non-response on some questions

  7. HIV care cascade during the first year of HIV diagnosis • Factors associated with ART initiation: • CD4 ≤250 cells/μL: aOR = 3.90, 95%CI: 1.05 – 14.50 • Age ≥30: aOR = 4.11, 95%CI: 1.13 – 14.91 69 42 32 (42.3% of TG women on ART) 26 11

  8. Correlates of virological suppression (N = 69) * Significant at p < 0.10 and entered into the multivariable model

  9. Correlates of virological suppression among transwomen on ART (n = 26)

  10. Sub-analysis: Cascade of HIV care 2002-2006 and 2007-2012Impact of the new legislation

  11. Limitations • Retrospective study • Focus on transwomen enrolled in HIV care • Small sample size

  12. Conclusions • Low rates of engagement across the HIV Care Cascade • High proportion of substance use, sex work, and unemployment → broader risk environment of TGW shaping HIV outcomes • Novel and culturally appropriate interventions tailored for HIV-infected TG women are urgently needed

  13. Challenges & future directions • Since August 2013 in Hospital Fernández: • Multidisciplinary team: infectious diseases, endocrinology, mental health, substance use, social services • Offer of comprehensive health services adapted to TG women needs
