Exposure to neurotropic pathogens has been hypothesized to be a risk factor for the development of bipolar disorder (BD). However, evidence so far is inconsistent. We, therefore, analyzed the seroprevalence and titer levels of IgG antibodies against several herpesviruses and Toxoplasma gondii (T. gondii) in plasma of 760 patients with a bipolar disorder, 144 first-degree matched relatives and 132 controls of the Dutch Bipolar (DB) Cohort using ELISA. In addition, we performed a literature-based meta-analysis on the seroprevalence of IgG antibodies against these pathogens (n = 14). Our results in the DB Cohort and subsequent meta-analysis (n = 2364 BD patients, n = 5101 controls) show no association between exposure to herpesviruses and bipolar disorder (HSV-1 [adjusted OR 0.842, 95% CI 0.567-1.230], HSV-2 [adjusted OR 0.877, 95% CI 0.437-1.761], CMV [adjusted OR 0.884 95% CI 0.603-1.295], EBV [adjusted OR 0.968 95% CI 0.658-1.423]). In the DB Cohort, we did not find an association between bipolar disorder and T. gondii titer or seroprevalence either [adjusted OR 1.018, 95% CI 0.672-1.542]. The overall OR was not significant for T. gondii [OR: 1.4, 95% CI 0.95-1.90, p = 0.09), but subgroup analyses in age groups below 40 years showed a significantly increased seroprevalence of T. gondii IgGs in BD [OR: 1.8 (95% CI 1.10-2.89, p = 0.021]. Our meta-analysis indicates that T. gondii exposure may be a risk factor for BD in certain subpopulations.

嗜神经病原体抗体与双相情感障碍之间的关联:荷兰双相情感障碍 (DB) 队列的一项研究和荟萃分析。



据推测,接触嗜神经病原体是双相情感障碍 (BD) 发展的危险因素。然而,迄今为止的证据并不一致。因此,我们分析了 760 名双相情感障碍患者、144 名一级匹配亲属和 132 名荷兰双相情感障碍 (DB) 对照者血浆中针对几种疱疹病毒和弓形虫 (T. gondii) 的 IgG 抗体的血清阳性率和滴度水平。使用 ELISA 的队列。此外,我们对这些病原体的 IgG 抗体的血清阳性率进行了基于文献的荟萃分析 (n = 14)。我们在 DB 队列和随后的荟萃分析(n = 2364 名 BD 患者,n = 5101 名对照)中的结果显示,接触疱疹病毒与双相情感障碍(HSV-1 [调整后 OR 0.842,95% CI 0.567-1.230], HSV-2 [调整后的 OR 0.877,95% CI 0.437-1.761]、CMV [调整后的 OR 0.884 95% CI 0.603-1.295]、EBV [调整后的 OR 0.968 95% CI 0.658-1.423])。在 DB 队列中,我们没有发现双相情感障碍与弓形虫滴度或血清阳性率之间的关联 [调整后 OR 1.018,95% CI 0.672-1.542]。弓形虫的总体 OR 不显着 [OR:1.4,95% CI 0.95-1.90,p = 0.09),但 40 岁以下年龄组的亚组分析显示 BD 中弓形虫 IgG 的血清阳性率显着增加 [OR :1.8(95% CI 1.10-2.89,p = 0.021)。我们的荟萃分析表明,弓形虫暴露可能是某些亚群中 BD 的危险因素。
