采用聚合酶链(PCR)技术及酶联免疫法对52例异位妊娠患者的宫颈及输卵管分泌物进行沙眼衣原体(CT)检测,并与对照组比较。结果(1)输卵管妊娠组宫颈CT阳性检出,酶联免疫法检出25例(48.1%),PCR法检出20例(38.5%);输卵管CT阳性酶联免疫法检出18例(34.6%),PCR法检出13例(25.0%)。(2)对照组宫颈CT阳性检出,酶联免疫法检出7例(25.0%),PCR法检出4例(14.3%)。输卵管妊娠组CT阳性检出率,酶联免疫法和PCR法均明显高于对照组(P<0.05)。本组资料显示,生殖道CT感染与异位妊娠相关。
The cervical and tubal secretions from 52 cases of ectopic pregnancy were tested for C. trachomatis by polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA), and compared with the control group. Results (1) CT was positive in tubal pregnancy group, 25 cases (48.1%) were detected by enzyme-linked immunosorbent assay and 20 cases (38.5%) were detected by PCR. Tubal CT positive enzyme-linked immunosorbent assay 18 cases (34.6%), PCR detected 13 cases (25.0%). (2) Cervical CT was detected in the control group, 7 cases (25.0%) were detected by enzyme-linked immunosorbent assay and 4 cases (14.3%) by PCR. The positive rate of CT in tubal pregnancy group, enzyme-linked immunosorbent assay and PCR were significantly higher than those in control group (P <0.05). The data show that genital CT infection and ectopic pregnancy related.
