The effect of pregnancy on the relapse rate of multiple sclerosis has been investigated. Obstetric and relapse histories of 52 women with clinically definite multiple sclerosis were obtained; there were 101 pregnancies of which 85 were at risk of a multiple sclerosis relapse. By comparing the number of relapses in the pregnancy period (9 months of pregnancy and 6 months immediately post partum) with the number in non-pregnancy periods for the same women, no increased risk of relapse during the pregnancy period was demonstrated. However, of the relapses that did occur during the pregnancy period, there was a significant reduction in the number of relapses in the first and second trimesters.
已对妊娠对多发性硬化症复发率的影响进行了研究。获取了52例临床确诊为多发性硬化症女性的产科和复发史;共有101次妊娠,其中85次有多发性硬化症复发风险。通过比较同一女性妊娠期(妊娠9个月和产后即刻6个月)的复发次数与非妊娠期的复发次数,未发现妊娠期复发风险增加。然而,在妊娠期确实发生的复发中,孕早期和孕中期的复发次数显著减少。
