目的前瞻性研究孕妇沙眼衣原体(CT)和解脲支原体(UU)的感染情况,探讨与UU、CT感染相关的危险因素。方法选取门诊行产前检查及住院待产的正常孕妇132例,采用ELISA方法检测母体血清中的抗UUIgG和抗CTIgG抗体。结果(1)孕妇抗UU IgG抗体检出率为17.42%,抗CT IgG抗体检出率为38.63%;不同孕周、不同年龄组、不同文化程度和不同职业的孕妇其血清中UU IgG、CTIgG的阳性检出率无显著性差异;(2)随着孕次的增加,UU IgG的阳性检出率显著增加;(3)自然流产次数与UU IgG的阳性检出率呈正相关;(4)曾患宫颈炎、阴道炎的孕妇CT IgG的阳性检出率明显增加。结论(1)孕妇年龄、不同孕周、不同文化程度与职业不应视为UU、CT感染的危险因素。(2)UU的感染与孕次呈正相关。(3)UU是引起自然流产、CT是引起先兆流产的危险因素。(4)宫颈炎、阴道炎是导致CT感染的一个危险因素。
Objective To prospectively study the infection status of pregnant women with Chlamydia trachomatis (CT) and Ureaplasma urealyticum (UU) and explore the risk factors associated with UU and CT infection. Methods 132 prenatal and prenatal pregnant women were selected from outpatients and anti-UUIgG and anti-CTIgG antibodies in maternal serum were detected by ELISA. Results (1) The detection rate of anti-UU IgG antibody in pregnant women was 17.42%, and the detection rate of anti-CT IgG antibody was 38.63%. The serum UU IgG, CTIgG in pregnant women of different gestational age, different age groups, different educational level and different occupations (2) The positive rate of UU IgG was significantly increased with the increase of the number of pregnancies; (3) The frequency of spontaneous abortion was positively correlated with the positive rate of UU IgG; (4) Had suffering from cervicitis, vaginitis in pregnant women CT IgG positive detection rate increased significantly. Conclusion (1) The age of pregnant women, gestational age, different educational level and occupation should not be regarded as risk factors of UU and CT infection. (2) UU infection was positively correlated with gestational age. (3) UU is caused by spontaneous abortion, CT is a risk factor for threatened abortion. (4) cervicitis, vaginitis is a risk factor for CT infection.
