Abstract

Objective: Cutaneous anergy testing evaluates delayed type hypersensitivity responses and is, in essence, an in-vivo measure of cell-mediated immune function at an epithelial surface. This study assessed the relationship of anergy test results with cervical infection by human papillomavirus (HPV) and cervical neoplasia in HIV-seropositive and seronegative women.

Methods: HIV-seropositive (n = 1029) and HIV-seronegative (n = 272) women enrolled in a long-term cohort study were followed semi-annually with HPV-DNA testing and cytology. Anergy was defined as unresponsiveness to Candida albicans, tetanus toxoid, and mumps antigen.

Results: Anergy was associated with the prevalent detection of squamous intraepithelial lesions [SIL; adjusted odds ratio 1.70; 95% confidence interval (CI) 1.16–2.48] in multivariable logistic regression models, and with the incident detection of oncogenic HPV (adjusted hazard ratio 1.24; 95% CI 0.99–1.56) in multivariable Cox regression models. These models adjusted for HIV infection, combined CD4 T-cell and HIV-RNA strata (13 separate strata to control optimally for their interactive effects), as well as other variables.

Conclusion: Cutaneous anergy testing may measure aspects of local cellular immune function in epithelial tissues that are important for the control of HPV and development of SIL, and that in HIV-seropositive women are not fully accounted for by circulating CD4 T-cell counts and HIV-RNA levels.
