6 Gender: Pre-ART Profile Women with and without HIV have higher CD4 counts than man (Main et al 1996; Delmas et al 1997) Adjusted for CD4 count, women have lower viral load than men (Sterling et al. 2001; Law et al. 2015) No difference in disease progression despite CD4 count and viral load differences (Napravnik et al. 2002; Sterling et al. 2001; Perez-Elias et al. 2014; Lee et al. 2015; Law et al. 2015) Pregnancy does not influence CD4 count or progression (Allegro et al. 1997) Women have lower serum CRP, scd14 and LPS than men (Mathad et al. J AIDS 2016)

7 START Study START Study Design HIV-positive ART-naïve individuals with CD4 count >500 cells/µl Immediate ART Group Initiate ART immediately following randomization N=2,326 Randomisation Stratified by clinical site Deferred ART Group Defer ART until CD4+ count declines to <350 cells/mm 3 or AIDS N=2,359 Primary composite endpoint, target = 213 Serious AIDS or death from AIDS Serious Non-AIDS Events and death not attributable to AIDS -CVD, ESRD, decompensated liver disease, & non-aids defining cancers

8 START Study START: Recruitment Sites START around the world Women: Recruited 12579/4/2009 (27%) to 23/12/ (11%) 1,539 (33%) 356 (8%) 1,174 (25%) 1,000 (21%) 109 (2%) 35 countries and 215 sites 2530 (54%) from low- and middle-income countries

9 START: Primary End-Point by Subgroup Primary End Point for Subgroups

10 START: Summary 1.8% of participants in the immediate vs. 4.1% in the deferred arm experienced the primary outcome Serious AIDS Events, Serious Non-AIDS Events, or Death 57% reduction in risk Evident for both AIDS and Serious Non-AIDS, greater for Serious AIDS Events, TB and cancer - most events occurred at high CD4 counts Consistent regardless of age, gender, race, region of the world, CD4 count, and viral load at entry Gender differences generally not analysed and reported apart from overall primary START outcome and a BMD sub-study Only 3% post-menopausal women in BMD analysis

11 Questions about Starting Treatment When to start: At the time of HIV diagnosis regardless of CD4 count and when the individual understands the goals of treatment and is ready to start

12 When to START Differences Gender in Differences Efficacy of ART in Efficacy between of men ART and wome Soon et al. AIDS Patient Care & STDs 2012

13 % with VL <50 cps/ml HIV-Positive Women in Germany 2015 vs Multicentre analysis On ART Virological suppression Knecht et al. 6 th International Workshop on HIV & Women 2016

14 UK ASTRA Cohort: Factors Associated with Virological Suppression after >6 Months of ART Women MSW MSM p=0.003 UK born/ not fluent English Non UK born/ fluent English UK Born p=0.16 Depression No Depression p<0.01 0,00 10,00 20,00 % with VL>50 copies/ml p values by Chi squared tests

15 ASTRA Cohort: Key Findings MSW and women compared to MSM more likely to have: detectable viral load viral load rebound after suppression Differences in virological outcomes between MSM and women largely explained by socio-economic circumstances They appear to have less impact for virological differences between MSM and MSW

16 Gender and ART Outcomes: Swiss Cohort 1984 men and 1941 women starting first-line ART Women had lower baseline viral load and higher CD4 counts Women more likely to switch ART or stop treatment in first year of ART, only partly pregnancy driven Lower probability of virological suppression in first 2 years of ART, abated after adjustment for HIV-related and sociodemographic factors Rosin et al. HIV Med 2015

17 Preferred First-Line ART Regimens EACS 2016* DHSS 2016 ABC 3TC DTG TDF FTC DTG TDF FTC RAL TDF FTC EVG/c TAF FTC EVG/c TDF FTC DRV/r TDF FTC RPV HLA-B*5701 negative Pre-treatment estimated CrCl 70 ml/min Pre-treatment estimated CrCl 30 ml/min CD4 count >200 cells and VL <100,000 cps *To be released in Autumn 2016

18 Questions about Selecting Treatment Does gender influence the choice of initial regimen? Does a discussion take place with women about treatment choices in accordance with different life stages and needs?

19 Questions about Selecting Treatment What to consider: Adverse effects of ART Child bearing potential, desire for or likelihood of pregnancy, and safety of ARVs in first trimester (or insufficient data for safety) Choice of contraception and drug-drug interactions

20 Toxicity in women Grade 4 anemia Gender and ART Outcomes CPCRA FIRST study: 55% used AZT, majority pre-menopausal African American women ART discontinuation or changes significantly greater in women for skin rash, neurological symptoms, constitutional symptoms, (and poor adherence) Immune activation and inflammation in women After 48 wks of ART, women have higher γifn and TNFα than men Tedaldi et al.

28 Conclusions In treatment-naive women, DTG/ABC/3TC was superior to ATV/r+TDF/FTC at 48 weeks Difference driven by lower rate of virological non-response and fewer discontinuations due to AEs in DTG arm DTG/ABC/3TC had a favorable safety profile Similar to overall safety profile for DTG from previous studies No treatment-emergent primary INSTI or ABC/3TC resistance mutations in the DTG/ABC/3TC group AE, adverse event; CI, confidence interval; INSTI, integrase strand transfer inhibitor 21st International AIDS Conference, July 2016, Durban, South Africa Orrell et al.

35 Stigma & Adherence in Women Women's Interagency HIV Study ( ) n=1168 Significant association between internalized stigma and sub-optimal selfreported adherence among ethnic minority groups (not observe with non- Hispanic whites) Depressive symptoms Internalised stigma Loneliness Low perceived social support Sub-optimal adherence Turan et al.

36 How Does Living with HIV Impact on Women s Mental Health? Online survey of respondents from 94 countries Social disadvantages correlated with mental health issues Before diagnosis After diagnosis Depression Self-blame Feeling of rejection A strong sense of isolation Anxiety Anorexia Spiritual isolation Suicidal feelings Harmful use of drugs/alcohol Percentage N= 489 Orza et al. J Int AIDS Soc 2015

37 Multiple Factors Influence Access, Engagement, and Treatment Outcomes in Women Experience or fear of violence Beliefs Isolation Drug dependency Depression Alcohol abuse Mental health vulnerabilities Socioeconomic circumstances Fear of blame Care responsibilities Fear of disclosure Fear of prosecution Food security

38 Conclusions: HIV-Positive Women Multi-faceted interventions are needed to promote access, engagement, outcomes, well-being Psycho-social support as part of comprehensive care Interventions aimed at moderating socioeconomic impact on health outcomes may improve outcomes in women a Research should strive for equity of access Clinical research should include measures of socioeconomic factors Reproductive care and beyond Prepare to address issues relevant to aging population Walcott et al.
