title: Distribution of human papillomavirus type 16 variants in human immunodeficiency virus type 1-positive and -negative women.
abstract: The prevalence of human papillomavirus type 16 E6 variant lineages was characterized in a cross-sectional study of 24 human immunodeficiency virus type 1 (HIV)-positive and 33 HIV-negative women in New Orleans. The European prototype was the predominant variant in the HIV-negative women (39.4 %), while in the HIV-positive women the European 350G variant was predominant (29.1 %). In exact logistic regression models, HIV-positive women were significantly more likely to harbour any variant with a nucleotide G-350 mutation compared with HIV-negative women [58.3 % vs 21.1 %; adjusted odds ratio (AOR)=6.28, 95 % confidence interval (CI)=1.19-46.54]. Models also revealed a trend towards increased prevalence of Asian-American lineage in HIV-positive women compared with HIV-negative women (25.0 % vs 6.0 %; AOR=6.35, 95 % CI=0.77-84.97). No association was observed between any variant and cytology or CD4 cell counts or HIV-1 viral loads. These observations reflect a difference in the distribution of HPV-16 variants among HIV-positive and -negative women, indicating that HIV-positive status may lead to increased prevalence of a subset of variants.
