Telomerase activity in HPV-associated vulvar vestibulitis

OBJECTIVE: To find a possible correlation between telomerase activity, mean telomere length and human papillomavirus (HPV) presence and type in vulvar vestibulitis. STUDY DESIGN: Twenty-two tissues excised during surgery for the treatment of severe vulvar vestibulitis and nine control tissue samples were tested for telomerase activity, mean telomere length, and HPV presence and type. RESULTS: Thirty-six percent of the tissues from vestibulitis patients were infected with HPV, mainly type 16/18, and none of the control tissue samples showed presence of HPV DNA (P < .02). Telomerase activity was detected in all tissues harboring HPV DNA, whereas only 64% of tissues without HPV DNA exhibited telomerase activity (P < .02). The mean telomere length was unchanged as compared to control samples. CONCLUSION: Telomerase activity in vestibulitis may be increased as a result of HPV infection, suggesting that HPV infection may play a role in the etiology of some cases of vulvar vestibulitis.
