苏州市农村不孕症夫妇弓形虫感染调查

目的 :调查不孕 (育 )症夫妇弓形虫感染水平 ,探讨弓形虫感染与不孕 (育 )症的关系。　方法 :随机选择苏州市吴中区不孕 (育 )症夫妇 178对 ,对其血清进行弓形虫感染和抗精子抗体及抗心磷脂抗体ELISA检测 ,并选择相应地区的正常健康生育夫妇 190对作为对照。　结果 :178对不孕 (育 )症夫妇弓形虫感染阳性家庭 6 2对 ,占不孕(育 )症家庭的 34.83% ,其中男性弓形虫感染阳性 30例 ,感染率为 16 .85 % ;女性弓形虫感染阳性 5 0例 ,感染率为2 8.0 9% ,均显著高于对照组相应的弓形虫感染率 12 .11%、6 .32 %、7.89% (P <0 .0 1)。弓形虫感染阳性病人的抗精子抗体阳性率为 32 .5 0 % ,显著高于弓形虫感染阴性病人中的抗体阳性率 15 .94 % (χ2 =10 .76 ,P <0 .0 1) ,相对危险比 (OR)为 2 .5 4。而两组中抗心磷脂抗体阳性率差异无显著性 (χ2 =1.6 3,P >0 .0 5 )。　结论 :弓形虫感染与不孕不育确有某种联系 ,弓形虫感染与抗精子抗体的产生可能有关联 ,它可能涉及不育 (孕 )症的致病机制

Survey on Infection of Toxoplasma Gondii in Infertile Couples in Suzhou Countryside

OBJECTIVES: To determine the level of anti-Toxoplasma antibody in serum of infertile couples to explore the relationship between toxoplasma infection and infertility. METHODS: Enzyme-linked immunosorbent assay (ELISA) was applied to detect the anti-Toxoplasma antibody, antisperm antibody (AsAb) and anticardiolipin antibody (ACA) in serum of 178 couples with infertility and 190 couples who had normal pregnant history. RESULTS: The positive result of Toxoplasma infection in the infertile couples was significantly higher than that in fertile couples which was 34.83% vs 12.11% (chi 2 = 26.72, P < 0.01) with the odds ratio 3.88. The positive result of serum AsAb in the Toxoplasma infected group was significantly higher than that in the no Toxoplasma infected group (32.50% vs 15.94%, chi 2 = 10.76, P < 0.01) with the odds ratio 2.54. CONCLUSIONS: Toxoplasma infection was related to infertility. The Toxoplasma infection and was posibly related to the antisperm antibodies which can be involved in the pathogenisis of infertility.
