Abstract

This study investigates the incidence and clearance of cervical and anal high-risk human papillomavirus (hrHPV) infection in kidney transplant recipients (KTRs) compared to immunocompetent controls. During 2016-2017, we enrolled 125 female KTRs and 125 female controls. Liquid-based cervical and anal cytology samples collected at enrollment and follow-up were tested for human papillomavirus (HPV) DNA using the CLART HPV2 test. All participants answered a questionnaire on lifestyle and sexual behavior at both examinations. KTRs had an increased age-adjusted risk of incident cervical hrHPV infection compared to controls (hazard ratio [HR] = 3.6, 95% CI = 1.2-11.2). Probability of cervical hrHPV clearance at 18 months was lower among KTRs (8.3%) than controls (66.7%). There was no statistically significant difference in anal hrHPV incidence between KTRs and controls (HR = 0.9, 95% CI = 0.4-2.0). Clearance of anal hrHPV was similar between KTRs and controls at 18 months. During the total follow-up, a lower anal hrHPV clearance, although not statistically significant, was observed among KTRs (HR = 0.3, 95% CI = 0.06-1.2). KTRs had higher incidence of cervical hrHPV and lower probability of clearance, especially of cervical hrHPV infections, than controls. Our findings support that KTRs are at increased risk of HPV infection and point to the need for targeted HPV prevention strategies, such as cervical cancer screening.
