We retrospectively analyzed the course and outcome of pregnancy in a group of 26 women with myasthenia gravis. Premature births were noted in 7.9% of pregnancies, the rate of cesarean section was 15.8%. Neonatal myasthenia was observed in 10 children born by 5 women (16% of the mothers). There were three neonatal deaths: two due to neonatal myasthenia, one in a child born with multiple congenital anomalies. Transient exacerbation of MG symptoms was observed during four pregnancies (10.5%). MG is not associated with increased risk for MG patient and the newborn. Giving birth to one child with transient MG increases the risk of transient MG in consecutive pregnancies.
