In utero diagnosis of congenital varicella zoster virus infection by chorionic villus sampling and polymerase chain reaction.
Varicella zoster virus infection acquired in pregnancy is reported to cause fetal damage in 5% to 10% of cases. We used polymerase chain reaction to attempt molecular diagnosis of fetoplacental varicella zoster virus infection in two patients. Tissue obtained by chorionic villus sampling in the second trimester was analyzed by polymerase chain reaction with a varicella zoster virus-specific primer, ORF-63, and was found to be positive in both patients. Viral cultures were negative. One patient elected pregnancy termination at 23 weeks. Southern blot hybridization of neonatal brain tissue for varicella zoster virus was negative. The second patient carried the pregnancy to term and was delivered of a normal infant. Varicella zoster virus immunoglobulin M and viral cultures were negative. The presence of viral deoxyribonucleic acid sequences in placental tissue does not correlate with fetal disease.
