BackgroundInformation on HPV knowledge in patients with genital warts is scarse as is the information on factors related to the impact on self-esteem and sex life among them.MethodsWe conducted a cross-sectional study in adult patients with a clinical diagnosis of genital warts (GW) attending a major private out-patient clinic in Bogotá, Colombia. Patients underwent biopsy for pathological diagnosis, HPV-DNA testing and completed a questionnaire assessing HPV knowledge, and the consequences of GW on self-esteem and sexual life. Differences in proportions were assessed with a chi2 test.Results106 men and 155 women had pathologic confirmation of GW. 51% of subjects had heard of HPV before consultation coming mainly from the media (82%). Less than half of the participants knew that HPV could be transmitted through non-penetrant sexual intercourse and only two thirds acknowledged HPV vaccine as a preventive measure against HPV infection. Impact on self-esteem was higher among women than men (90.3% vs 60.4%, [p < 0.01]). In men, factors related to a higher impact on sexual life were HPV awareness and age; in women they were higher education and anatomic location; external GW had a higher impact on sexual life in women (83% vs. 66%; [p = 0.05]).ConclusionsWe found a low awareness of HPV and low knowledge on the vaccine as a preventive measure for associated diseases even in patients suffering from genital warts, highlighting the need for communication and education on HPV. Greater impact on self-esteem in women might reflect higher health consciousness among Latin American women.

Epidemiological studies on benign lesions related to human papillomavirus (HPV) infection are scarce in Latin America. We enrolled 342 consecutive patients with lesions suspected of being genital warts (GW). All patients underwent confirmatory biopsy and GP5+/GP6+/- Reverse Line Blot HPV testing on frozen tissue. In 261 (81%) cases, the diagnosis was confirmed by histopathology and HPV was detected in 90.6% of men and 87.7% of women. HPV 6 was by far the most common type in both women (62%) and men (56%), followed by HPV 11 (∼20%). Co-infection with these two types occurred in 7% and 12% of women and men, respectively. HPV16 ranked third in prevalence, with 16% of patients testing positive. Twenty-five percent of cases tested positive for multiple HPV genotypes. Although HPV 6 and HPV 11 were the main types detected and no differences between men and women were observed, we found HPV 11 contributed more to GW aetiology compared with previous reports, showing a variability of HPV type distribution in GW across populations. This information is valuable baseline data in Latin America for future estimations of the burden of GW in men and women and shows the potential benefit obtainable by prophylactic vaccination against HPV types 6 and 11.
