Viral Load Determination and Biomarkers of High Risk Human Papillomavirus (HPV) - Types in HIV-positive Men

Human papillomavirus (HPV)-infection belongs to the most common sexually transmitted diseases worldwide. HIV-infected men having sex with men (MSM) are strongly associated with a higher prevalence of genital HPV-infection, a higher incidence of anal intraepithelial neoplasia (AIN), and, consecutively, an increased risk for anal cancer. Since the introduction of highly active antiretroviral therapy (HAART), the incidence of several viral-associated neoplasias has significantly fallen in HIV-infected individuals. At the beginning of the era of HAART, a justified hope existed that genitoanal HPV-related neoplasias would also decrease based on the success of HAART-induced immune restoration. However, HAART seems to have only a small impact on the natural history of AIN as observed in a cohort of HIV-positive MSM before and after the initiation of HAART. As AIN and cancer precursor lesions of the cervix, cervical intraepithelial neoplasia, share distinct clinical similarities, cytologic smear testing for AIN has been recommended to detect and treat early lesions. Thus, this prospective study mainly focuses on the predictive value of HPV-DNA load for the development and clinical progression of AIN in HIV-infected MSM. Moreover, the course of HPV viral load under therapy for anal intraepithelial neoplasia, e.g. topical treatment with imiquimod, will be evaluated. Additionally, immunohistochemical determination of several proliferative biomarkers, as well as cytokines, will be performed.
