Study design:

Cohort study 

研究目的:

验证奥氮平治疗过程中,肠道菌群-胆汁酸代谢轴异常是否与首发精神分裂症患者体重增加副作用相关,并明确其与奥氮平相关体重增加发生的关系。以奥氮平治疗后体重增加超过7%作为主要结局指标,比较体重增加组与非体重增加组在肠道菌群组成及胆汁酸代谢特征方面的差异,并评估其与体重增加的相关性。  

Objectives of Study:

To verify whether abnormalities in the gut microbiota–bile acid metabolic axis during olanzapine treatment are associated with weight gain as an adverse effect in patients with first-episode schizophrenia, and to clarify their relationship with the occurrence of olanzapine-associated weight gain. Using a body weight increase of more than 7% after olanzapine treatment as the primary outcome, this study will compare differences in gut microbiota composition and bile acid metabolic profiles between the weight gain group and the non-weight gain group, and evaluate their correlations with weight gain.

3.年龄18-65岁;
4.起始接受单药抗精神病治疗,其中主队列为奥氮平单药治疗,对照队列为非奥氮平抗精神病药单药治疗(如利培酮、阿立哌唑等);换药亚队列为在临床治疗过程中发生药物转换,包括非奥氮平抗精神病药治疗后改用奥氮平,或奥氮平治疗后改用其他抗精神病药;
5.能够配合完成临床随访、体格测量及生物样本采集;

2.First-episode schizophrenia or no prior systematic antipsychotic treatment, or only extremely limited prior exposure;
3.Aged 18–65 years;
4.Initiation of antipsychotic monotherapy, with the main cohort receiving olanzapine monotherapy and the control cohort receiving non-olanzapine antipsychotic monotherapy, such as risperidone or aripiprazole. The switching subcohort will include patients who undergo medication switching during clinical treatment, including switching from a non-olanzapine antipsychotic to olanzapine, or switching from olanzapine to another antipsychotic;
5.Able to cooperate with clinical follow-up, physical measurements, and biological sample collection;
6.Provision of written informed consent by the participant or their legal representative.

排除标准:

3.合并明确影响体重或代谢的内分泌疾病,如未控制的糖尿病、甲状腺功能异常等;
4.近期使用明显影响肠道菌群、胆汁酸代谢或体重的药物者,如长期抗生素、益生菌/益生元、糖皮质激素、减重药物等;
5.合并严重胃肠道疾病、消化吸收障碍或近期急性感染者;
6.妊娠期或哺乳期女性;
7.无法配合随访、样本采集或临床资料收集者;
8.研究者判断不适合入组的其他情况。

Exclusion criteria:

1.Previous long-term or systematic antipsychotic treatment, making it difficult to determine the baseline status;
2.Presence of severe physical diseases, such as severe hepatic, renal, or cardiovascular diseases, that may significantly affect body weight, metabolic status, or study safety;
3.Presence of endocrine diseases known to affect body weight or metabolism, such as uncontrolled diabetes mellitus or thyroid dysfunction;
4.Recent use of medications or agents that may significantly affect the gut microbiota, bile acid metabolism, or body weight, such as long-term antibiotics, probiotics/prebiotics, glucocorticoids, or weight-loss medications;
5.Presence of severe gastrointestinal diseases, malabsorption disorders, or recent acute infections;
6.Pregnancy or lactation;
7.Inability to cooperate with follow-up visits, sample collection, or clinical data collection;
8.Any other condition judged by the investigator to be unsuitable for study participation.
