对54例稽留流产绒毛组织及54例正常孕妇人工流产之绒毛组织,用PCR技术对解脲支原体(UU)和沙眼衣原体(CT)感染情况进行研究,并对绒毛UU-DNA阳性者用同法行血UU-DNA及CT-DNA检测。结果:稽留流产组绒毛UU-DNA阳性率55.6%(30/54),CT-DNA阳性率37.4%(20/54),人工流产组绒毛UU-DNA阳性率为11%(6/54),CT-DNA阳性率9.3%(5/54)。两组比较,UU-DNA阳性率和CT-DNA阳性率均有显著差异(均为P<0.05)。绒毛UU-DNA阳性者血UU-DNA阳性率为8.3%(3/36)。绒毛CT-DNA阳性者血CT-DNA阳性率为4%(1/25)。结论:UU感染或CT感染或UU与CT同时感染与稽留流产密切相关,是稽留流产综合病因之一。  相似文献

妊娠合并细菌性阴道病的研究   总被引:67,自引:2,他引:65  
目的:确定妊娠合并细菌性阴道病(BV)的发病情况,探讨妊娠合并BV与不良妊娠结局的关系。方法:根据临床表现和阴道革兰染色涂片镜检,对不同孕期的380名健康孕妇进行BV发病情况调查,并对其妊娠结局进行随诊。结果:妊娠合并BV的检出率为6.8%(26/380)。妊娠合并BV孕妇的产褥感染、新生儿感染及新生儿黄疸的发生率,依次为14.3%(3/21)、9.5%(2/21)及23.8%(5/21),高于无合并BV者(分别为2.2%、1.3%及5.4%,P<0.05,P<0.05,P<0.005)。结论:妊娠合并BV与母儿感染有关,有必要对妊娠合并BV孕妇进行治疗。  相似文献

Objective

To evaluate the effect of antichlamydial treatment and Chlamydia pneumoniae seroconversion on the incidence of pre-eclampsia among Egyptian primigravidae.

Methods

The present prospective study included 600 healthy normotensive primigravidae who attended an outpatient clinic at 10-16 weeks of pregnancy. A single venous blood sample was collected to test for C. pneumonia-specific immunoglobulin G (IgG) antibodies using an enzyme-linked immunosorbent assay. Seropositive women were randomly allocated to receive or not receive antichlamydial treatment before 20 weeks of pregnancy. Seronegative participants had another test at delivery for the presence of C. pneumonia-specific IgG to determine seroconversion. All participants were followed up for up to 8 weeks postpartum and observed for the development of pre-eclampsia.

Results

The rate of pre-eclampsia among seropositive participants differed significantly depending on whether the women received treatment or not (6.5% and 19.1%, respectively; P = 0.014). No statistically significant difference in the rate of pre-eclampsia was detected between seronegative participants who underwent seroconversion and those who did not.

Conclusion

The present results indirectly support the hypothesis that infectious agents (in particular C. pneumoniae) have a role in the development of pre-eclampsia. The findings also indicate that antichlamydial treatment might help to reduce the incidence of pre-eclampsia.  相似文献

Study Objective

To determine the prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis infection in sexually active Chilean adolescents and young adults. A comparative analysis was performed between genders to identify demographic, clinical, and sexual behavior characteristics to predict the occurrence of C trachomatis.

Design

Analytical observational study.

Setting

Santiago, Chile.

Participants

Two hundred eighty-six sexually active volunteers aged 24 years or younger (171 female and 115 male); 82.9% (237/286) of them were classified as having high socioeconomic status.

Interventions

Confidential survey and self-collected samples (urine for men and vaginal swabs for women).

Main Outcome Measures

Prevalence, demographic characteristics, symptoms, and sexual behavior characteristics.

Results

The prevalence rate of C trachomatis was 8.7% (10/115) in men and 8.8% (15/171) in women (P = .58). N gonorrhoeae was detected in 1 subject, whereas no T vaginalis cases were detected. In multivariate analysis, having some college education was protective (odds ratio [OR], 0.28; 95% confidence interval [CI], 0.09-0.89), whereas having a higher number of sexual partners was a risk factor (OR, 1.19; 95% CI, 1.1-1.3) for C trachomatis infection. The latter was also predicted by postcoital bleeding (OR, 4.6; 95% CI, 1.30-16.23) in the female model.

Conclusion

C trachomatis infection rates were similar between both genders. Protective characteristics for the occurrence of this infection were having some college education, lower number of sexual partners, and if female, the absence of postcoital bleeding. This study highlights the importance of C trachomatis screening among the Chilean affluent population younger than 25 years. However, further studies are needed in a more diverse and representative sample to recommend universal screening in Chilean adolescents and young adults.  相似文献

Objective. To investigate whether Chlamydia pneumoniae (Cp) infection is more common in women whose current pregnancy is complicated with preeclampsia (PE) as compared to pregnant women without PE. Methods. Thirty pregnant women with PE and 30 pregnant women without PE were studied between 29 and 30 weeks of gestation. The presence of an acute or chronic Cp infection was determined by the estimations of serum IgG, IgM, and IgA Cp antibodies. Results. None of the women were diagnosed as having acute Cp infection. Prevalence of chronic Cp infection was 53 and 66% in the PE and control groups, respectively (X2, p = 0.068). Conclusion. Chronic Cp infection is not more common in women whose pregnancy is complicated with PE as compared to pregnant women without PE. Therefore, no association between Cp infection and PE can be established.  相似文献

Immunoperoxidase localization of chlamydial antigens in acute salpingitis   总被引:3,自引:0,他引:3  
Seventy surgically excised fallopian tubes in which there was originally a diagnosis of acute salpingitis were reviewed histologically and screened for chlamydial antigens by the immunoperoxidase technique. Chlamydial antigens were localized within tubal epithelial cells in two of the 70 cases (3%). Endometrial specimens from these two patients were also positive for chlamydial antigens. There was no definite correlation between the histologic features of the salpingitis and chlamydial immunoperoxidase positivity.  相似文献
