Study design:

Cohort study 

研究目的:

在真实世界情境下,比较URSA患者在不同临床自然选择的管理策略(如免疫抑制类治疗 vs 非免疫抑制/常规支持治疗)下的受孕时间(TTP)与活产率差异,并识别影响结局的关键免疫与临床预测因子。  

Objectives of Study:

In a real-world setting, we aim to compare the differences in time-to-pregnancy (TTP) and live birth rates among URSA patients managed with different clinically selected strategies (e.g., immunosuppressive therapy versus non-immunosuppressive/conventional supportive care), and to identify key immune and clinical predictors of these outcomes.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1. 连续自然流产次数>=2次,且符合《复发性流产诊治专家共识(2022)》中URSA的诊断标准;
2. 年龄 18-45 岁;
3. 计划自然受孕或已自然妊娠<=6周;
4. 已完成标准化病因排查(染色体、解剖、凝血/免疫、内分泌、感染、男性因素、环境/心理)未明原因;
5. 签署知情同意;

Inclusion criteria

1. A history of >= 2 consecutive spontaneous abortions, meeting the diagnostic criteria for URSA as outlined in the Expert Consensus on the Diagnosis and Treatment of Recurrent Spontaneous Abortion (2022).
2. Age between 18 and 45 years.
3. Planning to conceive naturally or already naturally pregnant with a gestational age <=6 weeks.
4. Completed a standardized etiological workup (including chromosomes, anatomy, coagulation/immunity, endocrinology, infection, male factors, and environmental/psychological factors) with no cause identified.
5. Signed informed consent form.

排除标准:

1. 明确的特异性病因(如胚胎/夫妇染色体异常、显著子宫畸形、未控制甲/糖、APS等);
2. 合并严重心脑肝肾/造血/精神疾病或近期使用强免抑影响判断;
3. 不愿随访或依从性差;
4. 经研究者判断不适合参加本研究者。

Exclusion criteria:

1. Presence of a clear, specific etiological factor (e.g., embryonic or parental chromosomal abnormalities, significant uterine malformations, uncontrolled thyroid disease or diabetes, antiphospholipid syndrome (APS), etc.).
2. Comorbidity with severe heart, brain, liver, kidney, hematopoietic, or psychiatric diseases or recent use of potent immunosuppressive agents that could affect the study's outcome assessment.
3. Unwillingness to be followed up or poor anticipated compliance.
4. Any other condition that, in the investigator's judgment, makes the patient unsuitable for participation in the study.
