研究目的: |
1、主要研究目的:探究孕早期给予重组粒细胞集落刺激因子(rhG-GSF)是否能够改善不明原因反复妊娠丢失(uRPL)患者的妊娠结局; 2、次要研究目的: (1)研究rhG-CSF是否会增加uRPL患者妊娠期并发症、不良反应事件、新生儿不良结局的发生率; (2)根据分层随机化的分层因素分亚组探讨rhG-CSF对URPL患者有效性和安全性的影响。 |
||||||||||||||||||||||
|
Objectives of Study: |
1. Primary study objective: To investigate whether the administration of recombinant human granulocyte colony-stimulating factor (rhG-GSF) in the first trimester of pregnancy will improve pregnancy outcomes in patients with unexplained recurrent pregnancy loss (uRPL); 2. Secondary study objectives: (1) To study whether rhG-CSF will increase the incidence of pregnancy complications, adverse events, and adverse neonatal outcomes in patients with uRPL; (2) To assess the efficacy and safety of rhG-CSF in URPL patients according to stratification factors. |

纳入标准: |
1.年龄20岁至37岁(设置年龄上限为37岁的原因是染色体畸变导致的流产在高龄产妇中发生率较高,而该原因引起的流产不可能通过免疫调节来预防); 2.筛查时体重指数(BMI)介于15至29之间(既往2年两中心门诊患者BMI均值±2个标准差); 3.月经周期在21~35天之内,且仅1年中最长周期与最短周期只差不超过7天; 4.有反复妊娠丢失史,定义为2次及以上在妊娠24周之前的胎儿丢失(包含生化妊娠); 5.有自然受孕意愿且签署知情同意书。 |
||||||||||||||||||||||
|
Inclusion criteria |
1. Aged 20-37 years old (the reason for setting the upper age limit of 37 years old is that abortion caused by chromosomal aberrations has a higher incidence in advanced maternal age, and cannot be prevented by immunological regulation); 2. Body mass index (BMI) between 15 to 29 at screening (Mean±SD of out-patients from two centers in the past 2 years); 3. Menstrual cycle within 21-35 days, and the difference between the longest cycle and the shortest cycle only in 1 year is no more than 7 days; 4. History of recurrent pregnancy loss, defined as two or more fetal losses before 24 weeks of gestation (including biochemical pregnancy); 5. Willingness to conceive spontaneously and signing of informed consent form. |
||||||||||||||||||||||
|
排除标准: |
1.孕周大于5周+6天; 2.女性或其配偶染色体异常; 3.既往被诊断为不孕症(有规律性生活、未采取任何避孕措施至少1年仍未受孕)的患者; 4.排除免疫因素[包括自身免疫疾病:抗磷脂综合征、系统性红斑狼疮、未分化结缔组织病、干燥综合征、类风湿关节炎和系统性硬化症];易栓症[抗凝蛋白C、S缺乏、抗磷脂综合征和高同型半胱氨酸血症等];解剖因素包括先天性解剖异常[纵膈子宫、双角子宫、弓形子宫、单角子宫、双子宫、子宫发育不良和先天性子宫颈机能不全等]和获得性解剖异常[Asherman综合征、子宫颈机能不全、子宫腺肌症、子宫肌瘤等];内分泌因素[多囊卵巢综合征(PCOS)、黄体功能不全、高泌乳素血症(HPRL)、需药物治疗的甲状腺疾病、糖尿病等]等病史; 5.合并有以下疾病且症状尚未控制:哮喘、高血压、感染; 6.在筛查时或前3个月内出现以下实验室检查结果异常:血小板减少或增多(血小板计数<75,000/μL或>500,000/μL);中性粒细胞减少或增多(中性粒细胞绝对计数<1500/μL或>10000 /μL)、白细胞减少或增多(白细胞计数<3000 /μL或>15000 /μL),肌酐、谷丙转氨酶、谷草转氨酶、乳酸脱氢酶、碱性磷酸酶或尿酸>正常上限的1.5倍; 7.对粒细胞集落刺激因子或注射剂中的任何成分过敏; 8.既往3月内有粒细胞集落刺激因子使用史; 9.有其他试验药物的使用禁忌症。 |

Exclusion criteria: |
1. Gestational age > 5 weeks + 6 days; 2. Chromosomal abnormalities in females or their partners; 3. Patients previously diagnosed with infertility (no conception after regular sexual life without any contraception for at least 1 year); 4. Exclusion of immunological factors [including autoimmune diseases: antiphospholipid syndrome, systemic lupus erythematosus, undifferentiated connective tissue disease, Sjogren’s syndrome, rheumatoid arthritis and systemic sclerosis]; thrombophilia [anticoagulant protein C, S deficiency, antiphospholipid syndrome and hyperhomocysteinemia, etc.]; anatomical factors including congenital anatomical abnormalities [mediastinal uterus, bicornuate uterus, arcuate uterus, unicornuate uterus, duplex uterus, uterine dysplasia and congenital cervical insufficiency, etc.] and acquired anatomical abnormalities [Asherman syndrome, cervical insufficiency, adenomyosis, uterine fibroids, etc.]; endocrine factors [polycystic ovary syndrome (PCOS), luteal phase dysfunction, hyperprolactinemia (HPRL), thyroid disease requiring drug treatment, diabetes, etc.] and other medical history; 5. Combination of the following diseases with uncontrolled symptoms: asthma, hypertension, infection; 6. Present with the following laboratory abnormalities at screening or within the first 3 months: platelet decreased or increased (platelet count < 75,000/μL or > 500,000/μL); neutrophil decreased or increased (absolute neutrophil count < 1,500/μL or > 10,000/μL), white blood cell decreased or increased (white blood cell count < 3,000/μL or > 15,000/μL), and creatinine, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, alkaline phosphatase, or uric acid > 1.5 times of the upper limit of normal; 7. Allergy to granulocyte colony-stimulating factor or any component of the injection; 8. History of granulocyte colony-stimulating factor use within the past 3 months; 9. Other contraindications to the use of investigational drug. |
