Effects of maternal myasthenia gravis on pregnancy and birth examined

ST. PAUL, MN ? A 33-year study of all births by women in Norway with Myasthenia Gravis (MG) confirms that MG is associated with an increased risk for complications during pregnancy, including a threefold higher incidence of preterm rupture of the amniotic membranes, and twice the occurrence of delivery by cesarean section. The study is reported in the November 25 issue of Neurology, the scientific journal of the American Academy of Neurology.

Data for the study was collected from the Medical Birth Registry of Norway, based on compulsory notification of all births in the country. The study included 127 births by women with MG and the 1.9 million births by women without MG.

Women with MG had twice the rate of cesarean section (17.3 percent) when compared to the control group (8.6 percent). Preterm rupture of amniotic membranes occurred three times more often ? or 5.5 percent ? compared to 1.7 percent of the general population.

MG is a chronic autoimmune disease that causes muscle weakness. In people with MG, cells of the immune system make protein antibodies that block nerve impulses to their muscles. The major symptom of MG is muscle weakness that is worsened by fatigue and generally improves with rest. The prevalence of MG is estimated at about 1 in 10,000.

About 15 percent of infants born to women with MG are thought to develop neonatal MG through the passage of MG antibodies between the mother and newborn. The symptoms are usually mild or moderate, and include poor sucking and muscle tone. In this study, neonatal MG occurred in about 4 percent of the newborns, but another 8 percent were observed with MG symptoms following birth.

According to study author Jana Midelfart Hoff, MD, Institute of Neurology, University of Bergen, "Pregnancy does not appear to worsen the long-term effects of MG in women, however the disorder sometimes manifests itself during pregnancy, primarily during the first trimester or shortly after delivery
