氧化应激(OS)是由活性氧的产生与机体的抗氧化机制之间的不平衡引起的,并与各种疾病有关。包括抑郁症。抗氧化剂通过中和自由基来保护细胞,包括酶成分,如超氧化物歧化酶(SOD),过氧化氢酶(CAT),谷胱甘肽过氧化物酶(GPX),谷胱甘肽还原酶(GR),和谷胱甘肽S-转移酶(GST)。这些生物标志物的浓度可以量化OS。这项研究旨在收集过去十年中发表的有关抑郁症患者样本中酶促OS生物标志物浓度的可用信息。
方法:遵循PRISMA指南进行了系统评价,包括评估抑郁症参与者酶促OS生物标志物的原始科学文章,使用关键字和布尔运算符\"超氧化物歧化酶\"或\"过氧化氢酶\"或\"谷胱甘肽\"和\"depress*\"在数据库PubMed,SAGE日志,DOAJ,Scielo,Dialnet,还有Redalyc.
结果:初始搜索显示614个结果,只有28篇文章符合选择标准。观察到所有评估的氧化应激酶标记物显示抑郁症患者的显着增加或减少,由于所研究的抑郁障碍存在很大差异,分析的生物样本类型,和使用的技术。
结论:有证据表明酶促OS生物标志物与抑郁症之间存在关系,但是需要更多的研究来澄清这种关系的性质,特别是考虑到不同类型的抑郁症。
Oxidative stress (OS) results from the imbalance between the production of reactive oxygen species and the body\'s antioxidant mechanisms and is associated with various diseases, including depression. Antioxidants protect cells by neutralizing free radicals and include enzymatic components such as superoxide dismutase (SOD), catalase (CAT),
glutathione peroxidase (GPX),
glutathione reductase (GR), and
glutathione S-transferase (GST). The concentration of these biomarkers can quantify OS. This research aimed to gather available information published in the last ten years about the concentration of enzymatic OS biomarkers in samples from patients with depressive disorders.
METHODS: A systematic review was conducted following the PRISMA guidelines, including original scientific articles that evaluated enzymatic OS biomarkers in participants with depressive disorders, using the keywords and boolean operators \"superoxide dismutase\" OR \"catalase\" OR \"
glutathione\" AND \"depress*\" in the databases PubMed, SAGE Journals, DOAJ, Scielo, Dialnet, and Redalyc.
RESULTS: The initial search showed 614 results, with only 28 articles meeting the selection criteria. It was observed that all evaluated oxidative stress enzymatic markers showed a significant increase or decrease in patients with depressive disorders, due to a wide variability in the depressive disorders studied, the type of biological sample analyzed, and the techniques used.
CONCLUSIONS: There is evidence of the relationship between enzymatic OS biomarkers and depressive disorders, but additional studies are needed to clarify the nature of this relationship, particularly considering the different types of depressive disorders.
