Cytological diagnosis of genital ureaplasma urealyticum and its importance in cervical inflammation.

Abstract

Cervical smear cytology, which is a gynecological cervical cancer screening test, can provide information about the presence of pathogenic microorganisms or the inflammation they cause. Among them, Ureaplasma urealyticum (Uu), which is a subspecies of Mycoplasma was held responsible for high-grade cervical intraepithelial lesions and malignancy due to long-lasting complicated vulvovaginitis clinic. We aimed at investigating the role of Uu in the inflammatory process of the cervix and to describe the cytological features that enable it to be recognized microscopically in cervical smear test. Cervical smear and mycoplasma culture data of 123 women with complicated vulvovaginitis findings were evaluated. According to the Uu culture results, women were divided into two groups: the Uu-positive (n=59) and the Uu-negative group (n=64). The groups were compared in terms of cervical smear results, macroscopic view of the cervix, and secondary cytological evaluation results. The presence of inflammatory signs (83.1%) in the Uu-positive group was observed to be 83.1%, whereas 67.2% in the Uu-negative group, and the difference between the two groups was found to be significant (p=0.04). Besides, the difference in aggregated polymorphonuclear leukocytes (PMNL) between Uu-positive group (59.3%) and Uu-negative group (40.6%) was statistically significant (p=0.04). Similarly, nuclear atypia of epithelial cells in the Uu-positive group (33.9%) was observed to be higher than in the Uu-negative group (17.2%) (p=0.03). Uu causes inflammation of the cervix and cervical intraepithelial lesions. Aggregated PMNL observed in cervical smear cytology may be one of the findings that will give clues for Uu.
