Juelg E, Busch M, Lueger A, et al. - Because condylomata acuminata are caused by different genotypes of human papilloma viruses (HPV), researchers evaluated the frequency of 33 different types of HPV DNA in 49 patients with condylomata acuminata using the technique of polymerase chain reaction. Investigators found that 42% of the patients were infected with low-risk genotypes, and 21% of the patients tested positive for high-risk genotypes. In 36% of the patients, multiple infections with low- and high-risk genotypes were detectable. This information could serve as a basis for tracking the effectiveness of HPV vaccination in Austria, as the study findings are consistent with those from prior large-scale studies.
