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.

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.
