ABSTRACT
The occurrence of pregnancy in young female organ transplant recipients may sustain a high risk for prematurity and low rate of malformations in neonates. Therefore, it is necessary to counsel couples who want a child. In case of pregnancy, strict guidelines must be observed. Continuous exposure to CsA in utero seems to impair T-, B- and NK-cell development and function in neonates. This effect is prolonged throughout the first year of life. In addition, low levels of serum immunoglobulins occur at the same time. This leads to suggest a delayed administration of classical vaccinations (after the first 6 months of life) in view of the potential risks of both sub-optimal immunologic responses, and adverse events after the administration of live, attenuated vaccines in infants born from young female organ transplant recipients.
