Effekt av HCQ kombinert med LT4 på LBR hos Euthyroid kvinner med URPL og TPO-Ab (QT-LIFE)

27. september 2026 oppdatert av: Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University

Effekten av hydroksyklorokin kombinert med levotyroksin hos Euthyroid kvinner med skjoldbrusk antistoff positive og uforklarlige tilbakevendende graviditetstap: En multisenter, randomisert kontrollert studie

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.

Detaljert beskrivelse

Thyroid peroxidase antibodies (TPO-Ab) in euthyroid women are associated with recurrent pregnancy loss. According to 2017 Guidelines of the American Thyroid Association, administration of levothyroxine (LT4) to TPO-Ab-positive euthyroid pregnant women with a prior history of loss may be considered given its potential benefits in comparison with its minimal risk. However, it is a weak recommendation with low-quality evidence. Recently published randomised clinical trials showed that administration of LT4 does not improve pregnancy outcomes of euthyroid thyroid peroxidase antibody positive women with recurrent pregnancy loss. Published data showed TPO-Ab is related to immune imbalance. Hydroxychloroquine is a widely used immune modulator even in fields of autoimmune disorders during pregnancy and lactation. Nevertheless, the effect of hydroxychloroquine combined with LT4 on live birth rate of euthyroid women with TPO-Ab and unexplained recurrent pregnancy loss is unclear. Therefore, we designed a multicenter RCT to verify the study hypothesis that combined treatment of levothyroxine and hydroxychloroquine would improve the live birth rate of euthyroid women with thyroid peroxidase antibodies and unexplained recurrent pregnancy loss.

Intervensjon / Behandling
Eksperimentell: hydroxychloroquine and levothyroxine group

Corresponding oral treatment will be initiated after randomization and preconceptually, and continue to the end of pregnancy or until 60 weeks post-randomisation if pregnancy does not occur. Patients in the experimental group will be given a combined oral treatment of hydroxychloroquine (HCQ) and levothyroxine. Hydroxychloroquine sulfate tablets will be given at a total daily dose of 0.2g to 0.4g based on individual weight: patients weighing ≤46kg take HCQ tablets 0.2g/d, patients weighing >46kg and <62kg take HCQ tablets 0.3g/d, patients weighing ≥62kg take HCQ tablets 0.4g/d. Levothyroxine sodium tablets (Euthyrox, 50 μg) will be given 12.5μg ~50 μg daily based on patients' TSH levels and weights: TSH ≥ 2.5 mIU/L, the dosage is 50 μg/d; TSH < 2.5 mIU/L, the dosage is 25 μg/d; when the patient's weight is less than 50kg, the dosage is reduced by 50%.
Legemiddel: hydroxychloroquine and levothyroxine

Hydroxychloroquine sulfate tablets 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.

Levothyroxine sodium tablets will be given 12.5μg ~50 μg daily based on patients' TSH levels and weights: TSH ≥ 2.5 mIU/L, the dosage is 50 μg/d; TSH < 2.5 mIU/L, the dosage is 25 μg/d; when the patient's weight is less than 50kg, the dosage is reduced by 50%.
Legemiddel: Levothyroxine

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.
