HIV in Pregnancy - Doing More with Less

  1. 1. Mitchell J. Besser, MD Founder and Medical Director mothers2mothersDepartment of Obstetrics and Gynecology University of Cape Town 7 October 2009
  2. 2. Global HIV infections: 2007 33 million in world 22 million in SSA 5.7 million in SA• South Africa has less than 1% of world’s population but 17% of HIV infections• SA is one of the 12 countries which account for 3/4 of world’s HIV positive pregnant women UNAIDS 2008
  3. 3. Grim Reality•  The prevention-treatment gap is huge –  2.7 million new infections (2007) –  2.1 million adults and children died of HIV/AIDS UNAIDS: 2007, 2009 (2007) –  4 million people on treatment (2008) •  Approximately 1 million people started on treatment in 2008►Twice as many people become infected with HIV as start on treatment each year;► Twice as many die of AIDS as start on treatment.

  20. 20. • HIV incidence = new infections in women with a documented negative test in that pregnancy• MTCT rates: •  70% among women with incident HIV during pregnancy •  36% during breastfeeding• Where effective interventions have reduced transmission in identified women, new infections during pregnancy may be a major source of MTCT.
  21. 21. Impact of incident HIV infection in pregnancy•  A Botswana study showed: •  Among women testing negative in early pregnancy: •  1.3% were infected in 17 weeks before delivery, and •  1.8% were infected in the first postpartum year.•  Extrapolating this to the national Botswana figures: •  Estimate 950 women acquired HIV during pregnancy or first postpartum year, and infected 470 infants.•  Botswana National PMTCT program transmission data show •  13,900 women infected an estimated 620 infants (4.7%). Incident HIV is is thus estimatedaccount for 470/1090 (43%) Incident HIV thus estimated to to account for 470/1090 of infant infectionsof all infant infections in 2007 (43%) in 2007 T Creek, personal communication 2008

  30. 30. PMTCT Programs – 2001 Transmission Rates: 14-16%•  HIV testing – Point of care•  Single dose nevirapine to mother and baby•  Infant feeding choices•  Cotrimoxazole to infant from 6-weeks•  Infant testing at 12-18 months
  31. 31. PMTCT Program Interventions – 2008 Target: Transmission Rates: 2-5%•  HIV testing – Point of care•  CD4 counts•  Cotrimoxazole•  Combination Therapy – AZT from 28 weeks•  HAART during pregnancy if eligible –  Adherence –  Toxicity•  AZT+3TC to prevent nevirapine resistance•  Infant feeding choice/adherence – HIV-free survival•  ARVs during breast feeding•  Infant testing at 6-weeks

  35. 35. PMTCT Isn’t Working…•  Poor uptake of HIV testing•  Poor uptake of AZT/NVP by mother and baby•  Uncertainties regarding infant feeding: –  Choice –  Adherence –  Weaning•  Poor follow-up for infant testing•  Poor transition of mothers to ARV programs and Wellness Care during and after pregnancy•  Poor transition of babies to baby clinics and HIV/AIDS care
  36. 36. Causes•  Institutional   too few nurses and midwives   poor links between PMTCT and on-going HIV care   poor links between health care facility and community•  Societal   disempowered women   Stigma•  Same issues across Africa
  37. 37. mothers2mothers Vision Goal 1: PMTCTm2m envisions a world To prevent babies from contracting where babies are not HIV through mother-to-child born with HIV, where transmission and promote HIV-freeHIV+ mothers are alive survival.and healthy to care for Goal 2: Healthy mothers their families and and infants where HIV-positive To keep HIV-positive mothers andwomen are empowered their infants alive and healthy by to live positively increasing their access to health- sustaining medical care Goal 3: Empowerment To empower mothers living with HIV/AIDS, enabling them to fight stigma in their communities and to live positive and productive lives
  38. 38. Primary Objectives•  Increase HIV and CD4 testing during pregnancy•  Enhance uptake of antiretroviral medications:   PMTCT during pregnancy   ARVs during and after pregnancy•  Choice of and adherence to method of exclusive infant feeding;•  Appropriate weaning and introduction of complementary foods•  Infant testing•  Referral of mother and infant to follow-up care•  Disclosure•  Reducing stigma•  Partner involvement•  Empowerment – “living positively”
  39. 39. Secondary BenefitsPromote health systems and 4-prong approach to PMTCT:•  Attendance at antenatal and postnatal clinics•  Safe motherhood initiatives - deliveries in health care facilities•  Family planning – reduce the number of unwanted pregnancies•  Couples testing for primary prevention of HIV infection in discordant couples
  40. 40. Simple, Scale-able Model of CareMothers are a community’s single greatest resourceMothers living with HIV (Mentor Mothers) educate andsupport HIV-positive pregnant women and newmothers in health facilities •  Individual and group engagement •  Daily presence for education and support •  Mentor Mothers: professional members of health care team—paid for service
  41. 41. Site Coordinators and Mentor Mothers•  Recruited locally•  Selection criteria   Mothers   HIV-positive   Attended PMTCT   Disclosed•  Basic numeracy & literacy skills•  Mentors engaged for up to two years•  Site Coordinators manage services and relieve facility staff of management concerns
  42. 42. TrainingTraining cascade:National Trainer SC/MM Patients •  Curriculum based education •  2 weeks - Mentor Mothers •  3 weeks - Site Coordinators –  Mentor Mother training –  Management training •  Periodic top-up training
  43. 43. Points of Service•  Antenatal clinics•  Post-delivery wards before discharge•  Postnatal programs•  Targeted community outreach
  44. 44. m2m Does Not:•  Counsel for or perform HIV testing•  Provide medication•  Distribute formula m2m Does: •  Support medical services that do

  47. 47. Program ImplementationBuy-in from:•  National government health services•  District health services•  Facility managers and staff•  CBOs and civil societyCommunity involvement•  Facility staff and CBOs assist with staff recruitment   promotes integration of m2m into healthcare facilities and communities   links PMTCT care with other community services
  48. 48. Population Council - Horizons Study: Research Questions Does mothers2mothers: –  Increase HIV-positive women’s utilization of key PMTCT services? –  Improve PMTCT outcomes and psychosocial well-being?
  49. 49. Population Council - Horizons Study (2007)•  PMTCT –  95% of mothers received nevirapine –  88% of babies received nevirapine•  Care –  79% had CD4 counts –  88% knew CD4 count results•  Infant Feeding –  89% chose exclusive infant feeding method•  Family Planning –  70% using contraception•  Disclosure –  97% disclosed (4.4x non-participants)
  50. 50. Program Participants Report Better Psychosocial Well-being•  Pregnant participants were significantly more likely to feel they could: –  Do things to help themselves –  Cope with taking care of baby –  Live positively•  Postpartum participants were significantly more likely to feel less: –  Alone in the world –  Overwhelmed by problems –  Hopeless about future
