The clinical characteristics of pregnant women with epilepsy in China.

Abstract

Epilepsy during pregnancy and puerperium is infrequent, and it can induce severe complications and poor prognosis. Pregnancy in women with epilepsy (WWE) is usually uneventful. Previous studies have mainly focused on the effects of different treatments on prognosis. However, few articles have addressed if different epilepsy types were associated with a higher incidence of seizure breakthrough/recurrence and pregnancy outcomes. In the present study, based on a unique sample with a low incidence of epilepsy, we evaluated the main clinical characteristics of epilepsy patients. Mean age of pregnant WWE was 29.95±4.65 (range, 21-42) years. Pregnancies were at a mean gestational age of 33.80±9.14 (range, 7-41) weeks, and 88.24% (52/61) of WWE were in their third trimester. There was 9.84% (6/61) of pregnant WWE underwent abortion or induced labor in midpregnancy to ensure maternal safety. There was 75.41% (46/61) of pregnant WWE using antiepileptic drugs (AEDs), of which 52.46% (32/61) were taking a single AED and 22.95% (14/61) were using multiple AEDs. There was 47.54% (29/61) of WWE experiencing seizures during their pregnancy. We found that the type of epilepsy did not affect seizures during pregnancy or the prognosis. However, more pregnant WWE with hypertensive disorder had seizures compared with pregnant WWE without hypertensive disorder. The study highlighted a novel direction for effectively improving seizures during pregnancy and the prognosis of pregnancy-associated epilepsy.
