研究目的:

本临床研究为一项前瞻性、开放、单臂、单中心研究,针对激素依赖的EGE患者,采用FMT治疗重建肠道微生态结构,延长临床缓解无复发时间,探究基于移植的核心菌群疗法对于EGE的治疗有效率,安全性及肠道菌群重塑水平评价。  

Objectives of Study:

This clinical study is designed as a prospective, open-label, single-arm, single-center trial in patients with steroid-dependent EGE, aiming to restore the gut microbial ecosystem through fecal microbiota transplantation (FMT) and prolong relapse-free clinical remission. The study will further evaluate the efficacy and safety of this microbiota-based therapeutic approach, as well as the extent of gut microbiota reconstitution.

Inclusion criteria

1. Aged between 14 and 80 years old; 2. A confirmed diagnosis of eosinophilic gastroenteritis established through a comprehensive synthesis of clinical manifestations, endoscopic features, and histopathological findings (defined as peak eosinophil counts >=20 per high-power field in gastric mucosa and >=30 per high-power field in duodenal mucosa, across a minimum of five high-power fields within affected regions); 3. Meeting the diagnostic criteria for steroid-dependent EGE, characterized by the inability to taper glucocorticoid therapy to an equivalent prednisone dose of <=10 mg daily within three months following treatment with moderate-to-high-dose corticosteroids, or relapse occurring within three months after discontinuation of steroid therapy, and currently presenting with active disease; 4. Willingness and ability to adhere to the scheduled long-term follow-up; 5. Provision of written informed consent prior to any study-related procedures.

排除标准:

2.存在寄生虫感染、炎症性肠病、高嗜酸性粒细胞综合征、结缔组织病、恶性肿瘤、药物过敏以及其他任何可能导致嗜酸性粒细胞水平升高的疾病;
3.因腹腔积液或肠梗阻致活动明显受限或需要肠外营养支持;
4.妊娠或哺乳期;
5.无法按要求服用干预产品或完成检查;
6.语言表达障碍或精神疾病;
7.体检提示严重肝肾功能异常或HGB<80g/L;

10.入组前3个月内参与其他临床试验;
11.其他健康问题不适合参与研究;

Exclusion criteria:

1.Peripheral blood eosinophil count is normal;
2.Presence of parasitic infection, inflammatory bowel disease, hypereosinophilic syndrome, connective tissue disease, malignancy, drug allergy, or any other condition that may cause elevated eosinophil levels;
3.Significant limitation of activity or requirement for parenteral nutrition due to ascites or intestinal obstruction;
4.Pregnancy or lactation;
5.Inability to take the intervention product or complete examinations as required;
6.Speech impairment or psychiatric disorders;
7.Physical examination indicating severe liver or kidney dysfunction, or hemoglobin (HGB) < 80 g/L;
8.Presence of advanced-stage tumor;
9.Presence of severe immunodeficiency (congenital/acquired), intestinal obstruction, severe intestinal stenosis, perforation, or other conditions causing serious impairment of the intestinal barrie;
10.Participation in other clinical trials within 3 months prior to enrollment;
