Clinical-epidemiological characterization of human anal papilloma virus infection coloproctology unit: Central University Hospital Dr. "Antonio Maria Pineda"

Human papillomavirus (HPV) infection is one of the most common sexually transmitted viral diseases. A descriptive cross-sectional study was conducted with the purpose of clinically and epidemiologically characterizing anal HPV infection in patients who attended the Benign Orificial Pathology Consultation of the Coloproctological Unit at the Dr. "Antonio María Pineda" Central University Hospital, during the period March 2022 -February 2023, by selecting 288 patients whose average age was 47.09 ± 14.61 years, being the 41-50 years old group (29.17%) and the 51-60 years old group (19.44%) the most affected groups by pathologies of the anal region, with a predominance of male (54.17%). The sociodemographic characteristics with the highest frequency included married (48.61%) and single (47.22%); secondary level of education (44.44%) and traders (18.05%) and housewives (15, 28%) as predominant occupations. The risk factors were represented by onset of sexual intercourse between 16-20 years of age (65.28%), heterosexuality (91.67%), 22.22% reported having anal sex and 5.56% oral sex. Likewise, 5.56% were reported with a history of genital HPV and 4.17% were HIV positive. In addition, 48.61% stated not to use condoms. The initial clinical diagnosis included hemorrhoidal disease (30.55%), anal fistula (25%) and anal fissure (18.05%), and one patient (1.39%) with anal HPV infection. Anal cytology results showed 8.33% flat epithelial cells with cytopathic changes suggestive of HPV infection and 1.39% squamous cells with cytopathic changes suggestive of HPV infection: 50% mild inflammatory negative for malignancy and 33.33% flat epithelial cells without atypia. In conclusion, the anal cytology investigation should continue to determine the actual frequency of anal HPV infection. (AU)
