Epidemiological and molecular biological data suggest that β-human papillomavirus (HPV) can cause epithelial skin tumors, but the relationship remains unclear. A new approach to the diagnosis of HPV is based on the measurement of viral consistence. We examined 52 immune-compromised and immune-competent patients in order to identify the association of epithelial neoplasms with β-HPV. Determination of HPV was performed by polymerase chain reaction with hybridization-fluorescence detection in real-time. Amplification and detection were carried out with "Rotor-Gene" 3000 ("Corbett Research," Australia). To quantify the beta HPV genus, we used recombinant plasmid positive controls as well as control plasmid of β-globin fragments taken from human genes (Central Scientific Institute of Epidemiology Rospotrebnadzor). We have found that β-HPV DNA predominated in fibroepithelial polyps (64%) and in the apparently healthy skin (54%) of immune-compromised patients versus 47% in the skin of healthy donors. Mixed infection was detected in fibroepithelial polyps of 57% in the immune-compromised patients. Viral consistence in the fibroepithelial polyps was higher than in the apparently normal donors' skin. The high detection of HPV DNA was found in fibroepithelial polyps and in the apparently healthy skin of immune-compromised patients whereas a high level of HPV DNA was only found in fibroepithelial polyps.
