Investigating Potential Associations between Cervical Procedures and HIV Acquisition

Objective. Cervical human papillomavirus (HPV) infection has been associated with human immunodeficiency virus (HIV) acquisition in populations with a high prevalence of both infections. Procedures performed in the management of cervical dysplasia may facilitate HIV entry via mechanical injury. We sought to investigate the association between cervical procedures and incident HIV. Methods. Data on cervical cancer screening and procedures were collected in a cohort study evaluating the diaphragm for HIV prevention in 2040 women. In this secondary analysis, we investigated the association between cervical procedures and HIV acquisition. Results. Out of 2027 HIV-negative women at baseline, 199 underwent cervical procedures. Cumulative risk of HIV was 4.3% over 21 months of median followup (n = 88). Compared with women without cervical procedures, we observed no difference in HIV incidence after a cervical biopsy (RR 0.92, 95% CI 0.39–2.16), endocervical curettage (RR 0.29, 95% CI 0.07–1.22), or loop electrosurgical excision procedure (RR 1.00, 95% CI 0.30–3.30). Conclusions. In this cohort, cervical procedures were not associated with HIV incidence. This lack of association could be due to the small number of events.
