Prevalence of human papillomavirus (HPV) and HPV-16 genotyping by real-time PCR in patients with several cervical pathologies ABSTRACT Purpose: this study was planned to evaluate the prevalence of HPV (excepting type 16) and HPV 16 by real-time PCR in colposcopy patients and to interprete the results with age, age of first sexual intercourse (FSI), parity and Pap smear results. Methods: one hundred and two colposcopy patients (50 and 52 of the patients were classified as colposcopy positive and

Real-time nested amplifications of MY09/11 products were done by GP5+/GP6+ primers and Cyanine-5 labeled HPV and HPV 16 DNA specific probe after HPV DNA extraction by phenol chloroform isoamylalcohol. Results: HPV (excepting type 16) and HPV 16 were positive in 12% and 18% of the colposcopy positive patients respectively. HPV (excepting type 16) and HPV 16 were positive in 5.7% and 3.8% of the colposcopy negative patients, respectively. Conclusion: there was a statistically significant difference between colposcopy positive and colposcopy negative patients comparing HPV 16 with total HPV positivity (p = 0.021 for type 16 and p = 0.010 for total HPV) but there was not a statistically significant difference between colposcopy positive and colposcopy negative patients when we compared HPV (excepting type 16) positivity (p = 0.314). In conclusion, HPV detection and typing may be helpful for cervical cancer screening and prevention.
