Hybrid capture as a tool for cervical lesions screening in HIV-infected women: insights from a Brazilian cohort
ABSTRACT Introduction: Cervical cancer remains an important burden for HIV-infected women in the era of combination antiretroviral therapy. Recommendations for cervical screening in these women diverge and may include high-risk HPV (HRHPV) testing. We aimed to evaluate the clinical usefulness of a single HRHPV testing for cervical screening of HIV-infected women. Methods: 723 HIV-infected women from a Brazilian prospective cohort were included between 1996 and 2012. Inclusion criteria were: normal cervical cytology at baseline and having a HRHPV-test at baseline. We calculated incidence rates of any squamous intraepithelial lesion (SIL) and high grade SIL+ (HSIL+) and negative predictive values (NPV) within 12 and 36 months. Hazard Ratios were obtained using Cox proportional hazards regression models. Results: Incidence rate for both outcomes was low (9.9 cases per 100 PY [95% CI 8.8–11.0] for any SIL and 1.3 cases per 100 PY [95% IC 0.9–1.8] for HSIL+). Women with a HRHPV positive status at baseline had 1.7-fold (95% CI 1.3–2.2) and 3.2-fold (95% CI 1.5–7.1) increased risk of presenting any SIL and HSIL+, respectively, during follow-up. Negative-HRHPV test presented high NPV for both periods and outcomes (any SIL: 92.4% [95% CI 89.7–94.6] for 12 months and 80.9% [95% CI 77.2–84.3] for 36 months; and HSIL+: 99.8% [95% CI 98.9–100.0] for 12 months and 99.0 [95% CI 97.6–99.7] for 36 months). Conclusions: Incidence of any and high grade cytological abnormality was significantly higher among HIV-infected women with positive-HRHPV test. A single negative-HRHPV test helped reassure follow-up free of cytological abnormalities through three years of follow-up in HIV-infected women with negative cytology.
