Abstract

Objective: This study aimed to explore effects of adjunctive treatment with N-acetyl cysteine (NAC) on markers of inflammation and neurogenesis in bipolar depression.

Methods: This is a secondary analysis of a placebo-controlled randomised trial. Serum samples were collected at baseline, week 8, and week 32 of the open-label and maintenance phases of the clinical trial to determine changes in interleukin (IL)-6, IL-8, IL-10, tumour necrosis factor-α (TNF-α), C-reactive protein (CRP) and brain-derived neurotrophic factor (BDNF) following adjunctive NAC treatment, and to explore mediation and moderator effects of the listed markers.

Results: Levels of brain-derived neurotrophic factor (BDNF), tumour necrosis factor-α (TNF-α), C-reactive protein (CRP), interleukins (IL) -6, 8, or 10 were not significantly changed during the course of the trial or specifically in the open-label and maintenance phases. There were no mediation or moderation effects of the biological factors on the clinical parameters.

Conclusion: The results suggest that these particular biological parameters may not be directly involved in the therapeutic mechanism of action of adjunctive NAC in bipolar depression.

双相抑郁症n -乙酰半胱氨酸临床试验中炎症参数和神经发生的中介作用。

目的:本研究旨在探讨n -乙酰半胱氨酸(NAC)辅助治疗对双相抑郁症炎症和神经发生标志物的影响。方法:这是一项安慰剂对照随机试验的二次分析。在临床试验开放标签期和维持期的基线、第8周和第32周收集血清样本，以确定辅助NAC治疗后白细胞介素(IL)-6、IL-8、IL-10、肿瘤坏死因子-α (TNF-α)、c反应蛋白(CRP)和脑源性神经营养因子(BDNF)的变化，并探讨所列标志物的中介和调节作用。结果:脑源性神经营养因子(BDNF)、肿瘤坏死因子-α (TNF-α)、c反应蛋白(CRP)、白细胞介素(IL) -6、8或10的水平在试验过程中或在开放标签期和维持期没有显著变化。生物学因素对临床参数无中介或调节作用。结论:这些特殊的生物学参数可能与辅助性NAC治疗双相抑郁症的作用机制没有直接关系。
