Regarding different corticosteroids, prednisone and prednisolone have only a small proportion of active ingredients capable of passing the placenta and reach fetal circulation, and the therapeutic effects for fetus are not adequate to meet the expectation for clinical treatments.
Background: Doppler velocimetry studies of placental and fetal circulation can provide important information regarding fetal well-being providing an opportunity to improve fetal outcome.
Subsequent work using ivf and embryo replacement, established that fetal DNA could be detected in the maternal circulation as early as day 18 post-conception and concluded that the fetal DNA detected resulted from the trophoblast as the fetal circulation proper is not established until around day 28 post conception (60).
