Human papillomavirus-associated cervical cytologic abnormalities among women with or at risk of infection with human immunodeficiency virus.
OBJECTIVE
Correlates of abnormal human immunodeficiency virus cervical cytologic findings were examined among women infected with human immunodeficiency virus and uninfected women.


METHODS
We performed a cross-sectional analysis of baseline data on demographically similar women with infection or risk factors for it.


RESULTS
Among 1050 women without hysterectomy, squamous intraepithelial lesions were more common among women infected with human immunodeficiency virus than among uninfected women (18.8% vs 5.3%; P <.001). In multivariate analysis the association of squamous intraepithelial lesions with human papillomavirus infection was strong; adjusted prevalence ratios were 27 for high-risk, 25 for intermediate-risk, and 10 for low-risk types (95% confidence intervals, 12-58, 12-54, and 4-25, respectively). Much lower adjusted prevalence ratios were seen for the only other factor significantly associated with squamous intraepithelial lesions, namely, infection with human immunodeficiency virus in conjunction with a reduced CD4(+) cell count. Adjusted prevalence ratios were 1.9 for CD4(+) cell counts <200 and 1.6 for CD4(+) cell counts between 200 and 500 (95% confidence intervals, 1.2-3.0 and 1.0-2.5, respectively). Adjusted attributable fractions calculated for this study population indicated that if both human immunodeficiency virus and human papillomavirus were removed, 47.6% of the observed lesions with atypical squamous cells of uncertain significance and 93.4% of the observed squamous intraepithelial lesions would be prevented.


CONCLUSIONS
Squamous intraepithelial lesions are more common among human immunodeficiency virus-infected women and are associated most commonly with high- and intermediate-risk human papillomavirus types and secondarily with human immunodeficiency virus-associated immune compromise.
