Primary Outcome Measures:
  • cell-free viral load and/or cell-associated proviral load in breast milk [ Time Frame: Delivery, 3 months, and 6 months after delivery ] [ Designated as safety issue: Yes ]
  • concentration of vitamins A, B12, and E in breast milk [ Time Frame: Delivery, 3 months, and 6 months post-delivery ] [ Designated as safety issue: No ]
  • subclinical mastitis [ Time Frame: Delivery, 3 months, and 6 months after delivery ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • post-natal mother-to-child transmission of HIV [ Time Frame: Delivery, 3 months, and 6 months post-delivery ] [ Designated as safety issue: No ]
  • infant mortality and morbidity from diarrhea [ Time Frame: Delivery, 3 months and 6 months after delivery ] [ Designated as safety issue: No ]
  • a.) CCR5 expression in differentiating monocytes and differentiated monocyte-derived macrophages [ Time Frame: N/A (in vitro experiment) ] [ Designated as safety issue: No ]
  • HIV-1 replication in differentiating monocytes acutely infected with a subtype C HIV-1 clone, differentiated non-dividing MDMs acutely infected with the HIV-1 MJ4 clone, and differentiated non-dividing MDMs chronically infected with the HIV-1 MJ4 clone. [ Time Frame: N/A (in vitro experiment) ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples Without DNA

Breast milk samples collected from breast at delivery and at 3 month intervals thereafter.

Detailed Description:

The purpose of this study is to analyze stored samples and data collected during the conduct of the study "A Trial of Vitamins in HIV Progression and Transmission" (HD32257). The aims are to examine the effect of vitamin supplementation on HIV infected women during pregnancy

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

The data and samples used in this study are from HIV-infected pregnant women who participated in the "Trial of Vitamins in HIV Transmission and Progression". Between 1995 and 1997, 1,078 African, HIV positive women who were between gestatopm weeks 12 and 27 were recruited. They were followed until August 2003. This study was conducte among 771 of these women, for whom breast milk samples were available at delivery. There were no differences in baseline characteristics between this subset and the originally randomized group of 1,069.

Criteria

This study is analyzing samples previously collected from the study "A Trial of Vitamins in HIV Progression and Transmission" (HD32257).

The inclusion criteria in this study was:

  • HIV infected women presenting to antenatal care between 12 and 27 weeks of gestation
