Materno-fetal Transfer of Anti-HCMV-IgG Clinical Trial
Official title:
Examination of Diaplacental Transfer of IgG-antibodies Against Human Cytomegalovirus (HCMV) and Varicella-Zoster-Virus (VZV) at Premature and Mature Newborns
The aim of the study is to determine the total concentration of HCMV- and VZV-specific IgG-antibodies and the total concentration of neutralizing antibodies against HCMV in neonatal bloodstream depending on gestational age at birth.
For data gathering the investigators measure the main concentration of specific
HCMV-/VZV-IgG-antibodies and the concentration of neutralizing IgG-antibodies against HCMV
and VZV in maternal blood and in fetal bloodstream. Then the investigators compare the data
of mother and newborn. Therefore, the investigators use the following blood samples:
Mother: Venous blood sample taken at birth (+/- three days)
Newborn: Blood sample of umbilical cord (= fetal bloodstream) taken immediately after birth.
The investigators assign the data of each newborn (gestational age at birth) to the data of
their respective mother for statistical evaluation. After finishing the study the
investigators will destroy all residual blood.
