- Abstract
Objective: HPV genotype distribution varies by race/ethnicity, but is unclear whether there are racial/ethnic variations in HPV 16/18 integration in the host genome. We describe HPV16/18 infection and integration status in a racially/ethnically diverse sample of women with a recent abnormal Pap test., Methods: Patients (n=640) represent a subset of women participating in a clinical trial. Cervical swabs were tested for HPV16/18 DNA using type-specific polymerase chain reaction assays. Viral integration status was assessed using type-specific integration assays and categorized as fully integrated, fully non-integrated, or mixed. Unconditional logistic regression was used to generate unadjusted (OR) and adjusted odds ratios (aOR) to assess the association between self-reported race/ethnicity and risk of these outcomes., Results: Hispanic and non-Hispanic black women had half the odds of prevalent HPV16 compared to non-Hispanic white women (aORs: 0.43 and 0.45, respectively). The prevalence odds of HPV18 was less than half among Hispanic women (aOR: 0.48), but not significantly different between black and white women (aOR: 0.72). Among women with prevalent HPV16, the odds of fully integrated viral DNA were significantly higher among black women (aORs: 2.78) and marginally higher among Hispanic women (aOR: 1.93). No racial/ethnic differences were observed for HPV18 DNA integration., Conclusions: While HPV16 and 18 infections were less prevalent among Hispanic and black women compared to whites, their HPV16 DNA was more likely to be present in a fully integrated state. This could potentially contribute to the higher rates of abnormal cytology and cervical dysplasia observed among Hispanic and black women., (Copyright © 2017 Elsevier Inc. All rights reserved.)
