Defining Exposure • Exposure to the risk of infection • Exposure to an HIV affected family
Defining Exposure: Exposure to the risk of HIV infection (Principle risk) <1% 2% 5% 13% Cumulative risk by birth = 20% 65% 15% Cumulative risk by 2 years = 35%
Defining Exposure: Exposure to the HIV affected family • Orphan-hood—death of one or both parents • Malnutrition/under-nutrition—associated with rapid weaning of exposed infants • Diarrheal illness—associated with rapid weaning of exposed infants • Poverty—associated with ill parents unable to work
Defining Exposure: Exposure to the HIV affected family Mortality at 15 months median follow-up among infected and uninfected infants of HIV-infected mothers according to maternal CD4 count and survival (from Newell, et al., Lancet 2004; 364: 1236) % Mortality
Identifying Gaps: Maternal careUganda Oct 07-08 *From Oct 07 to March 08: 14,967 women tested, 1157 (7.7%) were positive, 794 (68.6%) received prophylaxis. From April to June 08: 4,652 women tested, 498 (10.7%) were positive, 753 received prophylaxis (105 multi-drug and 191 HAART: suggesting that most of the women receiving multi-drug and HAART were know HIV infected women who became pregnant while on therapy.
Identifying Gaps: Exposed child Follow-up 1st quarter O8, Uganda
ARVs given to HIV+ pregnant women who present in ANC or in L & D.AR Tanzania. Quarter ending 30 Jun 2008 • 30,000 pregnancies • 56% Tested • 47% any ARV
Exposed infants at Mwanza, TZ sites • Many mothers and children do not return for care- but number unknown • Some with (+) PCR never returned for result • Some with (+) 1st PCR had (-) 2nd PCR (error?) • About 25% of those who got PCR were (+) • Advised to wean at 6 months- effect on infant survival? No data. • PIs not being used in any infants • Conclusion: There is no evidence of benefit, and reason to be concerned regarding harm from early weaning and NVP resistance.
Plugging the Gaps • Adequate ARV therapy for pregnant women and new mothers • Adequate prophylactic coverage of infants • Protocol driven medical follow-up and testing of infants
Strategies: preserving maternal health • Earlier initiation of HAART in HIV positive women
Strategies: preventing transmission to infants ARV prophylaxis to protect breast feeding infants. • Promote the use of HAART in HIV positive pregnant women for the duration of pregnancy and breast-feeding. • Data on maternal HAART more “mature”
Enroll into Care Provide a package of support for HIV-exposed infants • All infected pregnant women and exposed infants are being routinely enrolled into HIV care and treatment programs • Robust infant nutrition counseling • Starting in antenatal period and continuing through infancy • Evidence-based counseling: risk of HIV infection or death from substitute feeding for the individual infant • proper guidance for women on how and what to feed the infant once weaned • Facilitating the general availability early infant virologic diagnosis • Training on site level DBS collection techniques • Emphasize clinical diagnosis in interim
3. Scripted Care • Implementing exposed infant medical records to assist with proper procedural care and testing. • What should be done at each visit. • Collects relevant clinical data
Strategies: Comprehensive follow up for mothers and exposed children • Community outreach initiated by the HIV care and treatment clinic. • key to integration into HIV care and treatment program. • Engage the HIV exposed child into care until sero-status known and exposure ended. • Ongoing follow-up of infants testing negative until ?: 18 months, 24 months, 36 months
Help going forward • Funding to HIV care and treatment clinics to develop and improve Maternal-child HIV care as part of their overall HIV care services. • Advocate changes in national guidelines to permit earlier initiation and use of HAART in-lieu of multi-drug prophylaxis.
