Abstract

Objectives

The aim of the study was to understand which human papillomavirus (HPV) types are involved in external genital warts (GWs) in a group of Argentinian women in Buenos Aires.

Methods

One hundred sixty consecutive women 15 to 45 years old with GWs were enrolled. All patients underwent confirmatory biopsy. In 150 of 160 patients, the diagnosis of GWs was confirmed by histology, DNA-HPV was investigated using polymerase chain reaction, and sequence analysis with generic primers MY09/11 was performed.

Results

HPV 6 and/or 11 was detected in 93.3% patients (140/150). HPV 6 was by far the most common type (80%), followed by HPV 11 (12.7%). Coinfection with these 2 types occurred in 0.7%. HPV 16 was found in 2% and HPV 73 in 0.7%.

Conclusion

HPV 6 and/or 11 are present in 93.3% (95% confidence interval, 0.9-1.0) of external genital warts in a group of Argentinian women in Buenos Aires and, therefore, could be prevented with HPV vaccine (NCT 015998779).
