Abstract

OBJECTIVE: This study aimed to examine the meaning and usefulness of sexually transmitted infection (STI) test when caring for patients who have abnormal cervical cytology and/or positive high-risk human papillomavirus (HPV) DNA test results. METHODS: Among patients who underwent liquid-based cervical cytology and HPV DNA tests at the Obstetrics and Gynecology outpatient clinic, 800 patients who showed abnormal cervical cytology were compared with 200 patients in the control group. Both groups were simultaneously tested via multiplex real-time polymerase chain reaction for seven types of STI-causative microorganisms. RESULTS: The positive rate of high-risk HPV infection in total STIs positive group was 1.47 times higher than that of total STIs negative group. The probability of a cytological diagnosis of a grade equal to or higher than atypical squamous cells-cannot exclude high grade squamous intraepithelial lesion (ASC-H) was significantly higher in patients testing positive for total STIs (1.46 times), Chlamydia trachomatis (3.21 times), or Mycoplasma genitalicum (3.58 times) than in those testing negative. The total STIs positive rate was significantly higher for those having a cytological diagnosis of a grade equal to or higher than atypical squamous cells of undetermined significance (ASC-US) when high-risk HPV test result was negative. CONCLUSION: Correlations were present not only between STIs and high-risk HPV infection but also between abnormal cervical cytology and STIs. Therefore, additional evaluation of STIs will be helpful to appropriately diagnose and treat patients with abnormal cervical cytology, positive results on high-risk HPV DNA test, or a cytological diagnosis of ASC-US despite negative high-risk HPV DNA test result.
