不明原因不孕不育妇女子宫内膜沙眼衣原体检测

用ＰＣＲ检测３２例不明原因不孕、不育妇女子宫内膜沙眼衣原体，结果发现：２１例不明原因不孕妇女有７例阳性；８例不明原因自然流产２次以上妇女有３例阳性；３例不明原因死胎史妇女中１例阳性。结果揭示：子宫内膜的沙眼衣原体感染是引起不孕、不育的重要因素。     

微量沙眼衣原体组织培养法的建立及临床应用

建立了微量沙眼衣原体组织培养法，并应用于不同人群的生殖道标本的沙眼衣原体培养。结果生殖道沙眼衣原体培养的阳性率：男性尿道炎患者１４７％（９／６１）；正常孕妇３３％（７／２１０）；急性和亚急性盆腔炎女性患者６７％（７／１０４）；性病门诊患者１８２％（４９／２６９）。由于９６孔培养板及倒置荧光显微镜的应用，微量培养法试剂用量少、过程简化；自制的抗沙眼衣原体单克隆抗体大大降低了培养后的染色成本，适用于大宗标本。     

The occurrence of Chlamydia trachomatis in the semen of men participating in an IVF programme

Chlamydia trachomatis is one of the most common causative agentsof sexually transmitted diseases. The authors studied the occurrenceof C.trachomatis in the semen of 184 asymptomatic men participatingin the IVF programme. Twenty-six (14.1%) of the 184 tested werepositive for C.trachomatis, these patients and their wives receivingdoxycycline capsules twice, 100 mg on the first day and 100mg/day for the following 13 days. This treatment was effectivein 88.5% of the cases and in the rest, treatment continued witherithromycin 250 mg four times/day for 2 weeks. The authorscompared the semen parameters (cell count, motility, morphology,bovine mucus penetration and hypo-osmotic swelling test) inthe infected and non-infected groups and observed no significantdifference between these two groups

Evaluation of a commercial test for antibodies to the chlamydial lipopolysaccharide (Medac) for serodiagnosis of acute infections by Chlamydia pneumoniae (TWAR) and Chlamydia psittaci

A commercial test (rELISA) based on a recombinant chlamydial lipopolysaccharide (LPS) antigen has been evaluated for the diagnosis of acute infections caused by Chlamydia pneumoniae (TWAR) and Chlamydia psittaci. This test and a microimmunofluorescence test (MIF) were compared in 160 patients with community-acquired pneumonia. Seventeen of nineteen cases with significant titre changes detected by rELISA were confirmed by MIF. The two remaining cases not confirmed by MIF were considered false-positive reactions. One case positive by MIF only was judged not to be a true-positive reaction. All three cases occurred in patients with Mycoplasma pneumoniae infection and may be the result of a mitogenic effect. High antibody titres have been used to indicate acute C. pneumoniae infection. We found high MIF or rELISA titres to be equally common in patients and controls; no association between the two tests was detected. An unexpected cross-reactivity between the rELISA antigen and parvovirus was observed, which might have diagnostic implications. Both MIF and rELISA detected acute C. pneumoniae and C. psittaci infection, and there was good agreement between the tests. Single serum diagnosis was generally not feasible with either MIF or rELISA.     

Pregnancy outcome in recurrent aborters is not influenced by Chlamydia IgA and/or G

PROBLEM: It is unclear whether chlamydia infection influences the miscarriage rate and immunological factors in patients with recurrent miscarriage. METHOD OF STUDY: Chlamydia DNA, IgA and IgG to Chlamydia trachomatis, natural killer cell activity, complement 3 (C3), C4, hemolytic complement, antinuclear antibodies, antiphospholipid antibodies, prolactin, activated partial thromboplastin time, prothrombin time and fibrinogen were examined in 504 patients with a history of two or more consecutive first-trimester miscarriages. Subsequent pregnancy outcomes were compared between cases with and without antibodies to C. trachomatis. RESULTS: Totals of 10 of 30 and 48 of 201 patients receiving no medication miscarried subsequently with and without chlamydia infection. Chlamydia IgA and/or IgG were associated with a high level of C3 but not other immunological and coagulatory parameters. CONCLUSION: Antibodies to C. trachomatis do not influence subsequent pregnancy outcome in patients with a history of recurrent miscarriage.     

Value of papanicolaou smear in detection of Chlamydia trachomatis infection

This study was undertaken to assess the value of Papanicolaou smear for the diagnosis of Chlamydia trachomatis infection. The study was both retrospective (groups I and II) and prospective (group III). Group I consisted of 41 smears with cytomorphological changes proposed by Gupta, Kiviat, or Shiina. Group II was a control group, consisting of 30 cytologically normal smears. All these smears were subjected to specific immunofluorescent (IF) staining under identical conditions to confirm the diagnosis. In group III, 40 consecutive duplicate cervical smears were collected from patients attending the Sexually Transmitted Disease Clinic. One smear was routinely examined, and the specific IF staining was done on the other smear. The results in all the three groups were analysed. It was concluded that Papanicolaou smear is not useful in the detection of Chlamydia trachomatis infection.     

Chlamydia trachomatis: time for screening?

Genital Chlamydia trachomatis infection is the leading cause of bacterial sexually transmitted disease in industrialised countries, particularly among young people. The consequences of chlamydial infection may involve urethritis, cervicitis, pelvic inflammatory disease, ectopic pregnancy, tubal factor infertility, epididymitis and prostatitis. In addition, chlamydial infection increases the risk of acquisition of human immunodeficiency virus and has been associated with cervical cancer. Although screening programmes exist in a number of countries, the continuously increasing prevalence of chlamydial infections demonstrates the necessity for health authorities to establish effective screening policies, and the importance of defining a comprehensive European screening policy is emerging.     

比较PCR酶免法与套式PCR法在不孕症中沙眼衣原体的临床检测

目的 比较PCR酶免法(PCR—ELISA)与套式PCR法(nPCR)法检测沙眼衣原体(CT)在不孕症宫颈分泌物中的临床意义。方法 应用PCR-ELISA法对185份宫颈分泌物进行CT检测，nPCR法对l12份宫颈分泌物进行CT检测，两种方法同时对38份宫颈分泌物进行检测，两种方法的检测结果进行对比分析。结果 PCR-ELISA法，CT阳性率为36．22％，(67／185)。nPCR法检到法CT阳性率为19.64％(22／112)两种方法同时检测的CT阳性率分别为34.21％及13．16％。PCR-ELISA与nPCR法比较差异有显著性(P＜0.05)。结论 PCR—ELISA法检测CT比nPCR法更敏感，特异，简单，并且没有EB污染等优点，结合临床治疗结果分析更适用于对长期慢性CT感染不孕症的诊断。
