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.

抗神经性病原体的抗体与双相情感障碍之间的关联:荷兰双相(DB)队列研究和荟萃分析。

已经假设暴露于神经营养性病原体是双相情感障碍(BD)发生的危险因素。但是,迄今为止的证据并不一致。因此,我们分析了760例双相情感障碍患者,144个一级配偶亲属和132个荷兰双相(DB)对照患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进行队列研究。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队列研究和随后的荟萃分析(n = 2364 BD患者,n = 5101对照)中显示,疱疹病毒暴露与双相情感障碍(HSV-1 [校正后的OR为0.842,95%CI 0.567-1.230]之间没有关联, HSV-2 [已调整OR 0.877,95%CI 0.437-1.761],CMV [调整后的OR为0.884 95%CI 0.603-1.295],EBV [调整后的OR为0.968 95%CI 0.658-1.423]。在DB队列中,我们未发现双相情感障碍与弓形虫滴度或血清阳性率之间存在关联[校正OR 1.018,95%CI 0.672-1.542]。弓形虫的总体OR值不显着[OR:1.4,95%CI 0.95-1.90,p = 0.09),但低于40岁年龄组的亚组分析显示,BD中弓形虫IgG的血清阳性率显着升高[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。
