The Efficacy of Hydroxychloroquine Combined With Levothyroxine in Euthyroid Women With Thyroid Antibody Positive and Unexplained Recurrent Pregnancy Loss：A Multicenter, Randomized Controlled Study

Sponsor

Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University

Enrollment

796 participants

Start Date

Nov 15, 2024

Study Type

INTERVENTIONAL

Conditions

Recurrent Pregnancy Loss Euthyroid With Thyroid Antibodies

Summary

The goal of this clinical trial is to learn if combined treatment of levothyroxine and hydroxychloroquine would improve the live birth of euthyroid women with thyroid peroxidase antibodies and unexplained recurrent pregnancy loss. Researchers will compare combined treatment of levothyroxine and hydroxychloroquine to a treatment of levothyroxine alone to see if combined treatment works to improve live birth of euthyroid participants with thyroid peroxidase antibodies and unexplained recurrent pregnancy loss. Participants will: * Receive combined treatment of levothyroxine and hydroxychloroquine or treatment of levothyroxine alone every day at least 8 weeks before pregnancy, and continue their treatment till the end of pregnancy. * Visit the clinic 4 weeks and 8 weeks after their treatments, and every 12 weeks before they get pregnant for checkups and tests. During their pregnancy, they will visit the clinic before gestation of 12 weeks, and will be followed up with phone call in the second trimester and after parturition.

Hydroxychloroquine sulfate tablets (Fenle, 0.1g) will be given at a total daily dose of 0.2g to 0.4g based on individual weight as described above. During the study, if TSH is higher than 4.0 mIU/L or exceeds the lower limit of the reference range of the center in the first trimester, or TSH level exceeds the normal range of the center during the second or the third trimester, subjects will be instructed to suspend the medication and visit the Department of Endocrinology.

DRUGLevothyroxine

Levothyroxine sodium tablets (Euthyrox, 50 μg) will be given 12.5μg \~50 μg daily based on patients' TSH levels and weights as described above. During the study, if TSH is higher than 4.0 mIU/L or exceeds the lower limit of the reference range of the center in the first trimester, or TSH level exceeds the normal range of the center during the second or the third trimester, subjects will be instructed to suspend the medication and visit the Department of Endocrinology.
