研究目的:

本研究旨在评估抗生素联合口服乳酸杆菌GR-1&RC-14治疗在慢性子宫内膜炎患者中的疗效,探讨益生菌对炎症反应的调节作用、微生物群的变化及其对患者临床症状的改善效果,从而为益生菌作为慢性子宫内膜炎患者在辅助生殖治疗中的潜在应用提供科学依据。  

Objectives of Study:

This study aims to evaluate the efficacy of antibiotic therapy combined with oral Lactobacillus GR-1 & RC-14 in the treatment of patients with chronic endometritis, exploring the regulatory effects of probiotics on inflammatory responses, changes in microbiota, and their impact on improving clinical symptoms. The findings will provide scientific evidence for the potential application of probiotics as an adjunctive therapy for patients with chronic endometritis undergoing assisted reproductive treatment.

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)年龄范围:20-42岁; (2)AMH>1.1ng/ml,月经周期25-37天,相对规律; (3)确诊慢性子宫内膜炎:宫腔镜典型的慢性子宫内膜炎表现或病理CD138≥5个/HPF; (4)同意参与研究并签署知情同意书:理解研究流程并自愿参与。

Inclusion criteria

(1) Age range: 20-42 years old; (2) AMH > 1.1 ng/ml, menstrual cycle 25-37 days, relatively regular; (3) Diagnosis of chronic endometritis: typical hysteroscopic findings of chronic endometritis or pathological CD138 >= 5 cells/HPF; (4) Agree to participate in the study and sign the informed consent form: understand the study procedures and voluntarily participate.

排除标准:

(1)最近接受抗生素治疗:在过去一个月内接受过抗生素治疗的患者,因其可能影响益生菌的作用效果。 (2)最近使用益生菌:在过去两个月内使用过益生菌的患者,排除其他益生菌的干扰。 (3)患有严重的妇科炎症或其他生殖系统疾病:如急性盆腔炎、严重未处理的输卵管积水等,可能干扰研究结果。 (4)有重大肝肾功能异常:因肝肾功能不全可能影响药物和益生菌的代谢。 (5)对益生菌或研究中使用的其他药物过敏。 (6)排除复发性流产、反复种植失败。

Exclusion criteria:

(1) Recent antibiotic treatment: patients who have received antibiotic treatment within the past month, as it may affect the efficacy of probiotics. (2) Recent use of probiotics: patients who have used probiotics within the past two months, to exclude interference from other probiotics. (3) Severe gynecological inflammation or other reproductive system diseases: such as acute pelvic inflammatory disease, severe untreated hydrosalpinx, etc., which may interfere with study results. (4) Significant liver or kidney dysfunction: as hepatic or renal insufficiency may affect the metabolism of drugs and probiotics. (5) Allergy to probiotics or other drugs used in the study. (6) Exclusion of recurrent miscarriage or repeated implantation failure.
