The data available on vaginal intraepithelial neoplasia (VAIN) and infection by HIV are scarce. We therefore aimed to review the clinical presentation, management, and survival outcomes of VAIN in this group of women.
This is an observational cohort study of women diagnosed with VAIN for a 23-year period. Clinical characteristics and outcomes were analyzed according to women's HIV infection status. Disease-free and progression-free survival were compared between groups.
Twenty-two of 87 women were HIV positive (25.3%) compared with the HIV-negative group, HIV-positive women were younger (median age = 39 vs 57 years, p < .001) and more frequently smokers (p < .001). They also presented with multifocal and multicentric disease more often (p = .004 and p = .033, respectively) in relation to infection by human papillomavirus. All HIV-positive women were receiving antiretroviral treatment. The median time from the diagnosis of HIV to the development of VAIN was 14 years (range = 1–22 years). There were no significant differences in survival outcomes between groups.
HIV-positive women are at an increased risk of developing VAIN and frequently present at a younger age with multifocal and multicentric disease. Vaginal intraepithelial neoplasia lesions can develop many years after the initial diagnosis of HIV infection reason why prolonged surveillance is essential to enable prompt diagnosis and treatment.
