Integrative Approach to Diagnosis of Genital Human Papillomaviruses (HPV) Infection of Female

Human papillomavirus (HPV) is a virus from the papillomavirus family that is capable of infecting humans. Some types of HPVs cause warts, while others can lead to cancers of the cervix, vulva, vagina, penis, oropharynx and anus. High-risk human papillomavirus (hr HPV) has been detected in almost all cervical squamous cell carcinomas and adenocarcinomas. All patients examined by colposcopy. Cervical swab is routinely done and patients are screened with both HPV DNA by Real Time Polimerase Chain Reaction (RT PCR) testing and Pap testing. Pictures obtained by colposcopy were examined by indirect Bi-Digital O-Ring Test (BDORT) by using reference control substance (RCS): HPV 16, HPV 18, and Integrin ±5 β1. BDORT was developed by Prof. Omura Y. of New York and received U. S. patent in 1993. For detection of HPV DNA we used RT PCR and standard Qiagen method which detect 18 types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68, 6, 11, 42, 43, 44) of HPV from smear. From 63 patients where is BDORT indicated presence of HPV, in 49 pateints (77,8%) RT PCR confirmed presence of HPV. From 63 patients in 54 patients (85,7%), we detected, by colposcopic exam, some kind of lesions associated with HPV infection. Results obtained by RT PCR: one type (1/18) of DNA HPV in 25 patients (51,02%), 2 types (2/18) in 15 patients (30,61%) and 3 types (3/18) in 9 patients (18,37%). Although BDORT results usually have higher sensitivity and detection rate is much higher, it can be used together with RT PCR in detection of HPV and cervical lesions associated with HPV infection.
