The aim of this study is to comparing the prevalence and correlationships between human papillomavirus (HPV) and Chlamydia trachomatis (CT) infection in cervical samples among women with abnormal cervical cytology.


This study was included three hundred seventy four patients with a abnormal liquid-based cytology in Dankook University hospital. All of them underwent HPV DNA test and CT analysis with polymerase chain reaction. All patients also went through colposcopic directed cervical biopsies or Loop Electrosurgical Excision Procedure, conization. The histo-pathologic results were classified as normal, cervical intraepithelial neoplasia (CIN) 1, CIN 2, CIN 3 and carcinoma in situ (CIS).


Abnormal liquid-based cytology patients were pathologically proven to have CIN. Among 374 patients, the number of within normal limits (chronic cervicitis) and koilocytosis was 186 cases (49.7%), CIN 1, 64 cases (17.1%), CIN 2 16 cases (4.3%) CIN 3, 55 cases (14.7%), and CIS, 53 cases (14.2%). HPV DNA positive patients were 235 cases and HPV DNA negative patients were 139 cases. The impact of CT infection seems not to interfere with the development or even the progression of CIN. Thirty one patients had positive infection of CT (8.3%) and 343 patients were negative infection of CT (91.7%). Both HPV and CT positive infected patients were 25 cases (6.7%) in abnormal cytologic women. The correlation between HPV and CT DNA positive among women with abnormal cytology was statistically significant. (P=0.022)


This study suggests that CT infection is associated with HPV infection, but the clinical significance of the association between CT and HPV infection remains to be elucidated.
