Background: Cervical cancer is the most common cancer in women. High-Risk HPV types are known as the main agents involved in genital and cervical malignancies. There may be co pathogens like STIs that are involved in enhancing the susceptibility and progression to cervical neoplasia. This study was conducted to detect C. trachomatis, HSV-2 and M. genitalium using qPCR in women suffering from cervical intraepithelial neoplasia, HPV infection and non cancerous- non HPV subjects for the association of burden of genital disorders.
Materials and Methods: This descriptive study was performed on 195 Liquid Based Cytology (LBCs) specimens collected from women referred to private laboratories. Fifty, 98 and 47 samples were from women with known CIN, HPV positive and non-cancerous/non-HPV, respectively. HSV-2, C. trachomatis, M. genitalium and HPV genotypes have been detected using multiplex TaqMan Real Time PCR and PCR hybridization.
Results: A total of 148 HPV positive samples were included. HPVs 6 (35.13%), 16 (32.43%), 18 (21.62%), 11 (9.46%), 31 (9.46%), and 51 (9.46%) were the most common genotypes. Single, 2, 3, and more than 4 multiple HPV genotypes were detected in 46%, 29.7%, 14.2%, 10.1% cases, respectively. The prevalence of M. genitalium, C. trachomatis and HSV2 was 3 (1.54%), 24 (12.3%) and 1(0.5%), respectively. There were no statistically significant differences between these pathogens and cervical intraepithelial neoplasia (p≥ 0.05).
Conclusion: HR-HPV genotypes were more prevalent in genital infections and cervical cancer. It would seem early detection of dominant STI pathogens such as Chlamydia spp. gains due to effective prevention. Here, further research is needed to understand the co-infections burden of HPV genotypes with STIs in clinical manifestations.
