Abstract:
Objective To analyze the pregnancy outcomes and effect on fertility in women with Graves' disease after 131I therapy and the health status of their newborns.Methods From year 2009 to 2012,a total of 102 female patients with Graves' disease,who were pregnant during propylthiouracil (PTU)/L-thyroxine (euthyrox) maintenance treatment,were retrospectively recruited.The subjects were divided into 131I therapy group (n=57) and non-131I therapy group (n=45).The time interval between 131I (non-131I) therapy and getting pregnant were at least 6 months.They were followed for their pregnancy outcomes.During the pregnancy period,recorded parameters included serum thyroid biochemistry,dose of PTU/euthyrox,health conditions of the newborns and termination of pregnancy.Medication compliance,delivery mode,baby gender and body weight between the 2 groups were compared byx2 test,Mann-Whitney u test,Fisher exact test and two-sample t test.Results Ninety-seven patients had normal labor.In 131I therapy group and non-131I therapy group,15 vs 22 patients were treated by PTU,31 vs 18 by euthyrox and 11 vs 5 without any medication during pregnancy (x2=5.69,P＞0.05).The medical compliance (PTU and euthyrox: u=163.50,233.50,both P＞0.05) was similar between the 2 groups.The delivery mode (natural labor/cesarean: 36/19 vs 28/14,x2 =0.016),baby gender (male/female: 32/23 vs 18/24,x2 =2.239) and body weight ((3.18t0.47) vs (3.07±4.17) kg,t=1.154) were also similar between the 2 groups (all P＞0.05).Condusion Women of reproductive age with Graves' disease were found to have normal pregnancy after 131I therapy,on the condition that their thyroid function could be reasonably controlled and maintained by the proper medication before and during pregnancy.
