[Anal intraepithelial neoplasia (NIA) and infection with human papillomavirus (HPV) in anoreceptive patients].
BACKGROUND: An association between human papilloma virus (HPV) infection and progression to anal intraepithelial neoplasia (AIN) and epidermoid cancer has been established.
OBJECTIVE: To know the prevalence of low and high grade AIN, as well as HPV infection in an anoreceptive patients group, infected or not, by human immunodeficiency virus (HIV).
MATERIAL AND METHODS: All patients with anoreceptive sexual relations were considered in this study. Patients who accepted anal citology and high definition anoscopy and biopsies with a follow-up not minor of 3 months were included.
RESULTS: Forty-four patients were included: 40 male (90.9%) with average age of 31 years. Anal cytology showed inflammatory alterations in 21 patients (28%), low grade intraepithelial lesion in 23 (52%); there were not patients with high grade epithelial lesion. According to the high definition anoscopy, there were low grade intraepithelial lesion in 42 patients (95%) and high grade in 2 (5%). Biopsy showed low grade intraepithelial in 26 patients (59%), high grade in 4 (9%) and inflammatory alterations in 14 (32%). The prevalence of AIN and HPV infection was 68% in both diseases. The HIV infection was associated with the presence of high grade AIN (p=0.002, OR 47.7)
CONCLUSIONS: There is a high prevalence of AIN and HPV infection between patients with anoreceptive sexual relations. The HIV infection is a risk factor for the development of high grade AIN.
