研究目的:

抑郁症目前仍以药物治疗为主,约三分之一的抑郁症患者对抗抑郁药反应不佳,其耐药机制并不清楚。已知添加5-甲基四氢叶酸(5-MTHF)可明显改善SSRI耐药的抑郁症患者的临床症状,提示SSRI耐药与叶酸代谢异常有关。亚甲基四氢叶酸还原酶(MTHFR)是叶酸代谢中的一个重要酶,参与5-MTHF的生成及DNA甲基化。MTHFR的多态性可改变MTHFR的酶活性并直接影响5-MTHF的形成。而MTHFR基因多态性是否与抗抑郁药疗效有关尚无直接证据。本课题首先在SSRI治疗有效和耐药的两组抑郁症人群中调查MTHFR基因多态性分布,基于MTHFR基因型探索全基因组和候选基因甲基化的改变与SSRI耐药的关系,最后对携带MTHFR风险等位基因的SSRI耐药患 者给予5-MTHF治疗,结合疗效评估,验证DNA甲基化异常参与了SSRI耐药的产生。本课题有助于寻找SSRI耐药的新机制,为精准个体化治疗提供依据  

Objectives of Study:

Major depressive disorder is still treated mainly by medicines now. About one-third of patients do not respond to antidepressants and the mechanism of treatment resistance is not clear. There is evidence that 5-methyltetrahydrofolate (5-MTHF) as an adjunctive therapy for SSRI-resistant depression can improve response rate and clinical efficacy, suggesting that the abnormal metabolism of folate may be related to SSRI resistance. Methylenetetrahydrofolate reductase (MTHFR) that is encoded by MTHFR is an important enzyme involved in the metabolism of folate cycle and is related to DNA synthesis and methylation. 5-MTHF is the product of folate catalyzed by MTHFR, and it is also the most active folate. Studies have found that the MTHFR polymorphism directly affects the formation of 5-MTHF. However, there is no direct evidence whether MTHFR gene polymorphism is related to the antidepressant response. This research will first investigate the distribution of MTHFR gene polymorphism in two groups of patients, those who are responsive to SSRI and those who are resistant to SSRI, and further explore the relationship between DNA methylation and SSRI-resistant depression according to genotypes of MTHFR polymorphic loci. Finally, SSRI-resistant patients with MTHFR mutations will receive treatment of 5-MTHF, combined with the evaluation of clinical efficacy and symptom, to prove that abnormal DNA methylation is involved in the SSRI-resistant depression. This study contributes to find the SSRI-resistant mechanism of MTHFR-related depression patients and provides a basis for precise and individualized treatment for patients with major depressive disorder.

纳入标准:

样本入组标准 ① 已签署知情同意,已完成各项测评; ② 经过 DSM-IV-TR 轴 I 障碍定式临床检查病人版(SCID-I/P)评估,符合DSM-IV 中抑郁症的诊断标准; ③ HAMD-17 评分≥17 分 ④ 年龄为 18-60 岁,男女不限; ⑤ 有接受 SSRI 药物治疗史。 SSRI 耐药筛选标准: 足量足疗程使用SSRI药物治疗无效。具体包括: ①药物剂量≥氟西汀40mg/d或其等价剂量(舍曲林≥100mg/d,帕罗西汀 ≥30mg/d,艾司西酞普兰≥15mg/d,西酞普兰≥ 40mg/d); ②每种药物使用时间不少于 6 周(≥6 周); ③终末疗效不佳评定标准:HAMD-17 总分较基线减分率<25%。 SSRI 治疗有效筛选标准: 服用 SSRI 药物治疗至少 6 周,治疗后 HAMD-17 总分≤7 分,被视为 SSRI治疗有效。

Inclusion criteria

Sample Inclusion Criteria: 1. The informed consent has been signed, and all assessments have been completed. 2. Assessed using the Structured Clinical Interview for DSM-IV-TR Axis I Disorders, Patient Edition (SCID-I/P), meeting the DSM-IV diagnostic criteria for depression. 3. HAMD-17 score >= 17. 4. Age between 18-60 years, no gender restriction. 5. History of SSRI medication treatment. SSRI Resistance Screening Criteria: Ineffectiveness of SSRI treatment at adequate dosage and duration. Specifically: 1. Medication dosage >= fluoxetine 40mg/day or its equivalent (sertraline >= 100mg/day, paroxetine >= 30mg/day, escitalopram >= 15mg/day, citalopram >= 40mg/day). 2. Each medication used for no less than 6 weeks (>=6 weeks). 3. Criteria for poor final treatment response: HAMD-17 total score reduction rate from baseline < 25%. SSRI Treatment Efficacy Screening Criteria: Taking SSRI medication for at least 6 weeks, with a HAMD-17 total score <= 7 after treatment, is considered effective SSRI treatment.
