Background 55% of all HIV-1 positive adults are
women of child bearing age. Seroprevalence rates among
pregnant women exceeds 30% in many urban populations in sub-Saharan Africa
![Page 4: The New DOH PMTCT Policy Challenges and Opportunities](https://reader031.vdocument.in/reader031/viewer/2022020500/56814f3a550346895dbcdb95/html5/thumbnails/4.jpg)
MTCT Rates ~10 - 30% in non-breastfeeding
population of HIV-1 positive women in more developed countries
25 -45% in breast-feeding populations in Africa

History of PMTCT and ARV interventions

PMTCT: The four-pronged strategy
• Primary prevention of HIV in parents-to-be
• Prevention of unwanted pregnancies
• Prevention of transmission from HIV-infected mother to infant
• Appropriate treatment and care

SA pMTCT Programme2001 - 2007
Nevirapine as single dose (sd) administration Dose= 1 tablet to mum at onset of labour
and a dose to baby within 72 hours after birth
Provision of infant formula for six months to mothers choosing this option.
NVP prevents MTCT by ~50% (Transmission Rates of approximately 10%)

Non-pregnancy related infections mainly HIV, TB and Pneumonia were the leadingcause of death in 38% of women
However probably an underestimate asonly 46% of women who died were tested for HIV, and 78% of those tested were HIV positivePMTCT is an opportunity to save the
lives of mothers and not only babies !
![Page 19: The New DOH PMTCT Policy Challenges and Opportunities](https://reader031.vdocument.in/reader031/viewer/2022020500/56814f3a550346895dbcdb95/html5/thumbnails/19.jpg)
National Antenatal Testing Rate was 75%
compared with 45% (2005/6)HIV prevalence rate
amongst ANC attendees = 29%
Compared with 30.2% (2005/6)Percentage of Women
receiving Nevirapine was 61%
Compared with 52% (2005/6)Percentage of Babies
receiving Nevirapine was 45%
Lower than 2005/6 BUT more likely reflecting better quality data

The New Revised PMTCT Policy2008
‘Routine offer of VCT’ (Provider Initiated) Addition of AZT (Dual Therapy) Emphasis on getting CD4 counts on all
pregnant women to start HAART in pregnancy (CD4 < 200 OR WHO stage 4)
Infant Feeding Options – better guidance Emphasis on infant diagnosis at 6 weeks
![Page 25: The New DOH PMTCT Policy Challenges and Opportunities](https://reader031.vdocument.in/reader031/viewer/2022020500/56814f3a550346895dbcdb95/html5/thumbnails/25.jpg)
SA pMTCT Programme2008 DUAL THERAPY
Women who need ARVs – get put onto this ASAP (CD4 count less than 200)
FOR WOMEN WITH CD4 COUNTS ABOVE 200 OR IF NOT YET ON ARVs (I.E ALL WOMEN)
Mother - AZT during pregnancy from 28 weeks gestation + single tablet Nevirapine in Labour
Baby – Single dose Nevirapine + AZT for 7 days (and in some cases upto 28 days)
Able to reduce MTCT to 5% with new policy !
![Page 26: The New DOH PMTCT Policy Challenges and Opportunities](https://reader031.vdocument.in/reader031/viewer/2022020500/56814f3a550346895dbcdb95/html5/thumbnails/26.jpg)
AZT TO BABY FOR 4 WEEKS IF:
Mother received no PMTCT
Mother received only nevirapine for PMTCT
Less than 4 weeks of AZT/HAART taken by mother
Mother diagnosed for the first time in labour or postpartum – AZT to baby best given within 12 hours of birth
![Page 27: The New DOH PMTCT Policy Challenges and Opportunities](https://reader031.vdocument.in/reader031/viewer/2022020500/56814f3a550346895dbcdb95/html5/thumbnails/27.jpg)
One out of four babies (25%) born to all HIV positive mothers will acquire HIV from their mother ( if no intervention is offered )
That means at least 75% of babies are uninfected at birth!

LABOUR AND DELIVERY At onset of labour, woman to take 600mg AZT (2
tablets) stat plus 200mg sd (1 tablet) nevirapine. If Nevirapine already taken previously with false
labour, do not repeat nevirapine dose and neonate receives standard post exposure prophylaxis.
Continue AZT 300mg 12 hourly at the usual times until the neonate is delivered.
Mother on HAART, continue treatment as usual during labour.

Repeat HIV testing at or around 34 weeks of gestation
About 5% of women will seroconvert during pregnancyHIV NEG ----------------- HIV POS

What about the women who haven’t been tested ?
No women should leave a healthcare facility without beingoffered an HIV test.
Not doing so is tantamount to being negligentRemember too our responsibility to both mother and the child

Challenges to Success of the Programme
Political leadership Testing rates below target Adequacy of human resources (e.g trained counsellors) Information transfer between facilities. Stigma Drug supply – NVP + AZT (no stock outs) No widespread campaign explaining benefits of programme Lack of integration with other services such as family
planning/CCMT/EPI Community and NGO involvement largely lacking Not seen as priority programme by healthcare facilities that
have other competing demands Public sector focussed rather than larger public health concern,
where only addressing attendees to the public health service
![Page 39: The New DOH PMTCT Policy Challenges and Opportunities](https://reader031.vdocument.in/reader031/viewer/2022020500/56814f3a550346895dbcdb95/html5/thumbnails/39.jpg)
Which Services need integration ? VCT – Family Planning VCT – PMTCT PMTCT – CCMT (ARV sites) PMTCT – Infant Diagnosis and Follow up
(IDFU) Infant Diagnosis and Paediatric ARV site EPI – IDFU TB - CCMT STI - CCMT
![Page 40: The New DOH PMTCT Policy Challenges and Opportunities](https://reader031.vdocument.in/reader031/viewer/2022020500/56814f3a550346895dbcdb95/html5/thumbnails/40.jpg)
Meeting the challenges Political Commitment Increase effective coverage - PMTCT programme in 100% of healthcare facilities
providing ANC Testing strategy needs revisiting – Provider initiated TC Adequate staffing with role clarification and systems improvement to enable
better coverage of all women. Prioritization of programme within healthcare facility. All staff at facilities must
understand importance of the programme. Programme leadership with dedicated and responsible team who monitor
progress in on-going manner i.e M&E at local level. Integration of PMTCT with CCMT services to enable smooth transfer of patients
needing treatment Community education and involvement in getting testing rates up. Mass media and educational campaigns to raise awareness of the programme and
it’s benefits. INFANTS - Need to ensure that ALL HIV exposed infants reap the benefits of an
enhanced PMTCT programme, which would include Abandoned infants (upto 50% have been noted to have had HIV exposure) Infants whose mothers are indisposed – death, coma, serious post-partum illness, mental
confusion Infants whose mothers refuse testing - Infants whose mothers refuse any intervention despite knowing their status

Opportunities Improve overall maternal antenatal care and outcomes
Through training on basic ANC Reduction in maternal mortality (NCCEMD) Improvement in basic infrastructure/equipment
Improve HIV testing rates amongst adults (women and men)
Expedited entry onto ARVs for women with low CD4 counts
Increasing access points for ARVs for patients Drastically reducing numbers of infected infants Establishing follow up for infants with early diagnosis
and treatment if needed Decreasing orphanhood
