Abstract

This meta-analysis investigated the neurophysiological underpinnings of systemic lupus erythematosus (SLE) by examining resting-state functional magnetic resonance imaging (rs-fMRI) profiles of SLE patients in comparison to healthy controls. Rs-fMRI studies up to November 10, 2022 were extracted from five principal databases: Medline, Web of Science, Embase, CNKI, and WanFang. The analysis included data from 13 distinct studies involving 934 participants. Applying the activation likelihood estimation (ALE) method, this study extracted coordinate data detailing functional disparities between the SLE cohort and controls. The findings indicated reduced activity in the right precentral gyrus (coordinates X = 26, Y = -6, Z = 72; ALE = 0.02155 and X = 26, Y = -18, Z = 68; ALE = 0.01767) and the right parahippocampal gyrus (X = 24, Y = -54, Z = 4; ALE = 0.01978). Conversely, increased activity was observed in the right middle frontal gyrus (X = 36, Y = 42, Z = 32; ALE = 0.01997) and the left lentiform nucleus (X = -18, Y = 14, Z = -8; ALE = 0.02057). These insights enhanced the understanding of the neurophysiological mechanisms in SLE, providing valuable information for diagnostic and therapeutic imaging strategies. Key Words: Systemic lupus erythematosus, Meta-analysis, Activation likelihood estimation, Resting-state, Functional magnetic resonance imaging.

系统性红斑狼疮脑功能异常:静息状态功能磁共振成像的荟萃分析。
本荟萃分析通过检查SLE患者的静息状态功能磁共振成像(rs-fMRI)特征,并与健康对照者进行比较,研究了系统性红斑狼疮(SLE)的神经生理学基础。截至2022年11月10日的Rs-fMRI研究数据提取自五个主要数据库:Medline、Web of Science、Embase、CNKI和万方。该分析包括13项不同研究的数据,涉及934名参与者。应用激活似然估计(ALE)方法,本研究提取了详细描述SLE队列和对照组之间功能差异的坐标数据。结果显示右侧中央前回活动减少(坐标X = 26, Y = -6, Z = 72;ALE = 0.02155, X = 26, Y = -18, Z = 68;ALE = 0.01767)和右侧海马旁回(X = 24, Y = -54, Z = 4;Ale = 0.01978)。相反,右侧额叶中回活动增加(X = 36, Y = 42, Z = 32;ALE = 0.01997)和左透镜状核(X = -18, Y = 14, Z = -8;Ale = 0.02057)。这些见解增强了对SLE神经生理机制的理解,为诊断和治疗影像学策略提供了有价值的信息。关键词:系统性红斑狼疮,meta分析,激活似然估计,静息状态,功能磁共振成像
