Brief Summary

Undifferentiated connective tissue diseases (UCTD) are known to increase the risk of pregnancy morbidities, including recurrent pregnancy loss. However, there is no consensus or guideline about the treatment for recurrent pregnancy loss in UCTD patients. Therefore, based on the tendency to thrombosis formation and placental inflammation in the pathogenesis of UCTD, this trial proposes to evaluate the effect of hydroxychloroquine with or without prednisone combined with anticoagulation on pregnancy outcomes in recurrent pregnancy loss patients with UCTD.

Detailed Description

Objective: To evaluate the effect of anticoagulation with or without immunomodulatory therapy on pregnancy outcomes of recurrent pregnancy loss with undifferentiated connective tissue diseases Design: a multi-center, randomised, open-label, paralleled study. Patients: Pregnant patients with recurrent pregnancy loss and undifferentiated connective tissue diseases without any known etiology for pregnancy loss (detailed in section 10).

Methods: 420 selected patients are divided into 3 parallel groups (detailed in section 8).

Randomization: Patients who present to relevant clinics for management of recurrent spontaneous abortion (RSA) will be evaluated for inclusion criteria and exclusion criteria by a formed physician. Once patient is eligible for the study, the co-investigator will obtain written patient's consent. Participants will be randomized into one of the 3 groups. Randomized numbers will be generated by pharmacology research personnel in Renji Hospital. Given the different administrated medications, neither the patient nor the provider will be blinded.

Follow-up: Consultation will be scheduled every 4 weeks from confirmed pregnancy until delivery. The co-investigator will complete a follow-up survey including clinical, biological data.

Missing data: Patients are willing to drop the study, unavailable, incompliant, with severe complications or with severe adverse effects. The missing data will be recorded in detail and be analysed with last pregnancy outcome.
