  Purpose

The aim of this single centre study is to measure maternal CD4+ t-cells in HiV exposed Newborns after spontaneous birth in comparison to cesarean section.

This may have an influence on the risk of vertical HiV transmission.

Primary Outcome Measures:
  • Maternal CD4+ t-cells in HiV exposed Newborns [ Time Frame: Six weeks after date of birth ] [ Designated as safety issue: Yes ]
    The maternal CD4+ t-cells are measured by microchimersimanalysis


Secondary Outcome Measures:
  • HiV transmission rate [ Time Frame: 6 month after birth ] [ Designated as safety issue: Yes ]
    Measurement of HiV PCR at the age of 6 month after birth

  • Analysis of HiV in maternal CD4+ t-cells [ Time Frame: 2 month after delivery ] [ Designated as safety issue: Yes ]
    HiV-PCR analysis from maternal CD4+ cells

  • Measurement of maternal CD8+ t-cells in the Newborn [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    Measurement of maternal CD8+ t-cells by microchimerismanalysis


Biospecimen Retention:   Samples With DNA

Umbilical Cord blood Blood from peripheral vene


Estimated Enrollment: 30
Study Start Date: August 2011
Estimated Study Completion Date: August 2014
Estimated Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts
Spontaneous delivery
Approximately 15 HiV exposed Newborns with low HiV transmission risk, born via spontaneous delivery.
Cesarean section
Approximately 15 HiV exposed Newborns with low HiV transmission risk, born via cesarean section.

Detailed Description:

At birth maternal CD4+ t-cells from umbilical cord blood and placenta blood are measured by microchimerism-analysis.

After 6 weeks the maternal CD4+ t-cells are measured in the blood of the babies blood.

Additionally we look for HiV in maternal CD4+ t-cells.
