6. What are the implications of inadequate PMTCT rollout? Estimates from the WHO Access report 2008: South Africa: Women in need of PMTCT intervention 220 000(180 000 – 260 000) Estimated PMTCT coverage57% (49 – 69%) Estimated transmission in unidentified HIV +ve women25% Results in:23 650 additional infected children annually Towards Universal Access Scaling up priority HIV/AIDS interventions in the health sector Progress Report 2008: WHO

8. HIV prevalence among pregnant women in South Africa, 1990 to 2008

9. Reality Check: a question of scale Annual pregnancies in HIV positive women: United States< 7,000 Namibia 7,600 Botswana 14,000 Europe 15,000 Kenya100,000 South Africa300,000 Soweto 9,000

10. Reality Check CD4 counts need to be available for HIV positive pregnant women in order to decide on appropriate treatment options, and few PMTCT services have moved to include CD4 at all health service levels Provision of more complex ART requires more laboratory and toxicity monitoring, additional procurement infrastructure, and more intensive follow up Most PMTCT services (based on antenatal care) do not yet have the capacity to deliver ART

11. Proportion of antenatal clients tested by district T Doherty, District Health Barometer, 2007/2008., HST 2009 The average HIV testing coverage rate for the metro districts was lower than the national average. Only two metro districts, City of Cape Town and City of Johannesburg achieved higher than the national average. The coverage in Ekurhuleni, Tshwane and especially eThekwini, with a 52% testing rate, is particularly concerning… National Average: 80%

12. Nevirapine uptake by district T Doherty, District Health Barometer, 2007/2008., HST 2009 National Average: 76%

13. Opportunities and Obstacles The Implementation Challenge

14. . Efficacy of PMTCT programs is related to more than just the PMTCT regimen used To provide PMTCT interventions - need to identify HIV- infected women during pregnancy. Regardless of what PMTCT intervention, it must reach and be accepted by the woman. Program efficacy is likely to be more related to PMTCT cascade efficacy than PMTCT regimen efficacy Coverage and linkages

22. Opportunity: Appropriate treatment and care PMTCT is a gateway to treatment Women who need ongoing antiretroviral treatment should start as soon as possible in pregnancy

23. “We need extraordinary measures to reverse the trends we are seeing in the health profile of our people…. we will be treating significantly larger numbers of HIV positive patients. It means that people will live longer and more fulfilling lives. ” President Jacob Zuma: 1 December 2009 "Shall I repeat garlic, shall I talk about beetroot, shall I talk about lemon... these delay the development of HIV to Aids-defining conditions, and that's the truth." Health Minister Manto Tshabalala Msimang, 7 June 2006 Opportunity: Regime change…..

24. Opportunity: Regimen change….. 2002 – SdNVP March 2008 – “dual therapy” AZT from 28 weeks and SdNVP ART at CD4 < 200/mm 3 April 2010 - AZT from 14 weeks/ sdNVP + “tail cover” ART at CD4 < 350/mm 3

25. Impact of dual therapy introduction in Kwazulu Natal The province rapidly implemented the revised PMTCT guidelines, bringing down transmission to as low as 4.3 percent in one district, and 7 percent on average. 38,000 women included in study: 36% HIV positive 66% received dual therapy, 14% NVP only, 13% started ART Transmission rates: 8,013 babies aged between four weeks and eight weeks tested at immunisation clinics, and found that of those whose mothers had received dual therapy, 5.6 percent were HIV-positive compared to 13.5 percent of babies whose mothers only received nevirapine.

31. Infant feeding

32. Infant feeding is one of the most difficult and most emotive issues in HIV management in low-resource settings Even with complete coverage of an effective peripartum ART intervention, an estimated 30,000 children will acquire infection through breastfeeding each year HIV transmission during this period remains a challenge in places where infant formula cannot be safely provided Infant feeding and HIV

33. A new postpartum transmission ABC……….? A A bstain B B e Faithful C C ondomise A A void breastmilk B B reastmilk only C C over with ARV

34. ARV prophylaxis of breastmilk transmission Maternal or infant prophylaxis: For women with CD4 >350/mm 3, who do not need ongoing ART, either Infant ARV Prophylaxis (with extended nevirapine dosing) or Maternal HAART for the duration of breastfeeding may be options to prevent Postnatal HIV transmission through breast milk

35. ARV prophylaxis through breastfeeding The 2009 Revised WHO Recommendations … provide two alternative options for women who are not on ART and breastfeed in resource-limited settings: 1) If a woman received AZT during pregnancy, daily nevirapine is recommended for her child from birth until the end of the breastfeeding period. OR 2) If a woman received a three-drug regimen during pregnancy, a continued regimen of triple therapy is recommended through the end of the breastfeeding period.

36. Future Directions Improving coverage of PMTCT services Improving access to more efficacious regimens Starting HAART in symptomatic women or those with CD4 < 350 Providing prophylaxis through breastfeeding – either as extended daily nevirapine to babies or as HAART to mothers PMTCT services remain key to achieving MDGs 4 & 5

37. PMTCT Program linkages Prevention of new infections in women Prevention of transmission to sexual partners Prevention of transmission to infants Family planning & reproductive health services Pre-ART care Antiretroviral therapy Infant diagnosis and care Male health care Circumcision PMTCT services Nutrition Support services Improving links to reproductive health services to prevent unwanted pregnancies Strengthening links to treatment and care services to ensure ongoing care
