Cervicitis is predominantly caused by Neisseria gonorrhoeae and Chlamydia trachomatis, which accounts for almost half of all the cases of cervicitis. The role of newer organisms like Mycoplasma genitalium and Ureaplasma sp. and association of bacterial load with cervicitis are also not well established. So the study aimed to determine the relative frequency of these organisms and their load in association with cervicitis cases from north India. A case-control study involving 300 women was conducted using quantitative real-time PCR from endocervical swabs for identification of organisms and quantification of bacterial load. Among 150 cervicitis cases, C. trachomatis, N. gonorrhoeae, M. genitalium and Ureaplasma parvum were detected in 5 (3·3%), 10 (6·6%), 37(24·6%) and 47 (31·3%) respectively. Old age (<0·001, chi-squared test) and irregular menstrual cycles (<0·001, chi-squared test) were significantly associated with cervicitis. M genitalium was the only organism to be associated significantly with cervicitis with regard to age (<0·031) and symptoms like discharge (P < 0·033, chi-squared test) and dysuria (P < 0·044, chi-squared test) in multivariate analysis. Our finding suggests that the bacterial load of these organisms is not significantly associated with cervicitis. However, we found significant association of M. genitalium infection with clinical characteristics of cervicitis cases.
宫颈炎主要由淋病奈瑟菌和沙眼衣原体引起,这两种病原体几乎占宫颈炎病例的一半。其他新病原体如生殖支原体和脲原体的作用以及细菌负荷与宫颈炎的关系尚未得到充分证实。因此,本研究旨在确定这些病原体及其与印度北部宫颈炎病例的相关性在相对频率和细菌负荷方面的情况。采用定量实时 PCR 法对 300 名女性的宫颈拭子进行检测,以确定病原体并定量细菌负荷,进行病例对照研究。在 150 例宫颈炎病例中,分别检测到沙眼衣原体、淋病奈瑟菌、生殖支原体和脲原体短小亚种 5 例(3.3%)、10 例(6.6%)、37 例(24.6%)和 47 例(31.3%)。年龄较大(<0.001,卡方检验)和月经周期不规律(<0.001,卡方检验)与宫颈炎显著相关。生殖支原体是唯一与宫颈炎显著相关的病原体,与年龄(<0.031)以及与宫颈炎相关的症状如分泌物(P<0.033,卡方检验)和尿痛(P<0.044,卡方检验)有关。我们的研究结果表明,这些病原体的细菌负荷与宫颈炎无显著相关性。然而,我们发现生殖支原体感染与宫颈炎病例的临床特征显著相关。
