The study of Wilson Disease in pregnancy management

Abstract Background: Pregnancy management in women with Wilson disease (WD) remains an important clinical problem. This research was conducted to investigate how to avoid worsening of WD symptoms during pregnancy and increase pregnancy success in women with WD by identifying the best pregnancy management approaches in these patients. Methods: The clinical data of 117 pregnancies among 75 women with WD were retrospectively analyzed. Related information of the fetus was also recorded and analyzed. At the same time, regression analysis was performed for data of 22 pregnant women without WD, as normal controls. Results: Of a total of 117 pregnancies among the 75 women with WD and 31 pregnancies among the 22control womenincluded in this study, there were 108 successful pregnancies and 9 spontaneous abortions. Among the 108 successful pregnancies, 97 women a history of copper chelation therapy before pregnancy; all 97 women stopped anti-copper therapy during pregnancy. The nine women with spontaneous abortion had no pre-pregnancy history of copper displacement therapy. The incidence of lower limb edema was higher in the WD group than in normal controls (P=0.036). Compared with the control group, there was a higher proportion in the WD group of male infants (P=0.022) and lower average infant birth weight (t=3.514, P=0.001). Conclusion: It is relatively safe for women with WD patients to become pregnant. The best management method for pregnancy in women with WD may be intensive pre-pregnancy copper chelation therapy and no anti-copper treatment during pregnancy.
