Role of Ureaplasma urealyticum and Ureaplasma parvum as Risk Factors for Cervical Dysplasia with Human Papillomavirus

Abstract

Human papillomavirus (HPV) can be transmitted sexually and causes cervical malignancies in women. Among the risk factors, sexually transmitted infections (STIs) caused by bacteria have raised concerns because they are asymptomatic and persistent and can increase the risk of HPV infection. This study assessed the correlation among Ureaplasma urealyticum, Ureaplasma parvum, Chlamydia trachomatis, and Mycoplasma hominis infections towards abnormal cervical cells positive for HPV. Seventy outpatients at the Colposcopy Outpatient Clinic, Dr. Cipto Mangunkusumo Hospital in Jakarta, Indonesia, were enrolled in this cross-sectional study. Viruses and bacteria were detected using polymerase chain reaction and compared with liquid-based cytology results for cervical cytology. Of the 70 patients, 24 (34.28%) showed abnormal cervical cytology. Among those with abnormal cervical cytology, C.trachomatis was reported in 1 patient (4.2%), M.hominis in 6 patients (25%), U.urealyticum in 13 patients (54.2%), and U.parvum in 10 patients (41.7%). Statistical analysis demonstrated an association between U.urealyticum and U.parvum infections and HPV infection (U.urealyticum p = 0.012; U.parvum p = 0.022). U.urealyticum and U.parvum were more prevalent than C.trachomatis and M.hominis in HPV-positive women, suggesting their role in HPV infection.
