研究目的:

探讨口服肠菌移植(Fecal Microbiota Transplantation, FMT)微胶囊作为辅助干预手段,在13–17岁神经性厌食症青少年患者中的疗效与安全性,评估其对营养状态、情绪症状、神经认知功能及肠道微生态的多维影响,探索“肠-脑轴”在进食障碍中的作用机制,为该类患者提供一种新型、安全、可行的整合治疗策略。  

Objectives of Study:

To investigate the efficacy and safety of orally administered microencapsulated fecal microbiota transplantation (FMT) as an adjunctive intervention in adolescents aged 13–17 years with anorexia nervosa, and to evaluate its multidimensional effects on nutritional status, affective symptoms, neurocognitive functioning, and the gut microbiome. This study further aims to explore the role of the gut–brain axis in the pathophysiology of eating disorders, thereby providing a novel, safe, and feasible integrative treatment strategy for this patient population.

干预措施:

Interventions:

组别:

FMT微胶囊干预组

样本量:

15

Group:

FMT microcapsule intervention group

Sample size:

干预措施:

连续6天,口服FMT微胶囊,每天早上一瓶。提前从冰箱冷冻层取出本次所需的一瓶胶囊,室温复温20分钟;之后倒入温水/酸奶等液体中(所有液体温度需在37°C以下)送服,切勿咀嚼。服药后建议散步30分钟以上,避免剧烈活动,以促进微胶囊通过胃部进入肠道。

干预措施代码:

Intervention:

For six consecutive days, participants will take oral FMT microcapsules, one bottle each morning. On each dosing day, one bottle of capsules will be removed in advance from the freezer compartment of the refrigerator and allowed to thaw at room temperature for 20 minutes. The capsules will then be administered by dispersing them into a liquid such as lukewarm water or yogurt (all liquids must be < 37°C) and swallowing them without chewing. After administration, participants will be advised to walk for at least 30 minutes and to avoid strenuous physical activity to facilitate gastric transit and promote passage of the microcapsules into the intestine.

干预措施:

连续6天,口服外观一致的安慰剂微胶囊,每天早上一瓶。提前从冰箱冷冻层取出本次所需的一瓶胶囊,室温复温20分钟;之后倒入温水/酸奶等液体中(所有液体温度需在37°C以下)送服,切勿咀嚼。服药后建议散步30分钟以上,避免剧烈活动,以促进微胶囊通过胃部进入肠道。

干预措施代码:

Intervention:

For six consecutive days, participants will take oral placebo microcapsules that are identical in appearance to the FMT microcapsules, at a dose of one bottle each morning. On each dosing day, one bottle of capsules will be removed in advance from the freezer compartment of the refrigerator and allowed to thaw at room temperature for 20 minutes. The capsules will then be administered by dispersing them into a liquid such as lukewarm water or yogurt (all liquids must be < 37°C) and swallowing them without chewing. After administration, participants will be advised to walk for at least 30 minutes and to avoid strenuous physical activity to facilitate gastric transit and promote passage of the microcapsules into the intestine.

随机方法(请说明由何人用什么方法产生随机序列):

随机分配序列由未参与试验临床环节的独立统计人员,采用专业统计软件生成,设置block长度为2以保障分组均衡,序列生成后加密存储并打印纸质版密封归档,由独立人员专人保管。

Randomization Procedure (please state who generates the random number sequence and by what method):

The random allocation sequence was generated by an independent statistician who did not participate in the clinical link of the trial using professional statistical software, with a block length of 2 to ensure group balance. After generation, the sequence was encrypted and stored, and a paper version was printed, sealed and filed, which was kept by the independent statistician specially.

盲法:

所有参与临床试验的研究者、受试者、干预实施人员、疗效评估人员、数据录入及统计分析人员均处于盲态,不了解受试者具体分组情况;仅独立序列保管人员及第三方编盲人员知晓分组信息,且严格遵守保密规定,不泄露任何相关信息。

Blinding:

All researchers, subjects, intervention implementers, efficacy evaluators, data entry and statistical analysis personnel participating in the clinical trial were in a blind state and did not know the specific grouping of subjects; only the independent sequence keeper and third-party blinding personnel knew the grouping information and strictly abided by the confidentiality regulations without disclosing any relevant information. Blind maintenance measures were set throughout the trial, and any personnel were prohibited from inquiring about or speculating on grouping information in any way.
