Highlights

  • Cervical and anal HPV infection is highly prevalent in women living with HIV.

  • Anal HPV infection is associated with cervical HPV infection.

  • Non-16/18 hrHPV genotypes were predominant at all anatomical sites.

  • Half of hrHPV infections could have been prevented by the 9-valent HPV vaccine.

Abstract

Background

Women living with HIV (WLWH) have elevated risk of human papillomavirus (HPV) related cancers.

Objectives

To assess prevalence, distribution and concordance of cervical, oral, and anal HPV infection, and predictors of oral and anal HPV in WLWH in Denmark.

Study design

WLWH followed in the Study on HIV, cervical Abnormalities and infections in women in Denmark (SHADE) were enrolled and examined for cervical, oral, and anal HPV infection. Logistic regression models were used to identify predictors of anal and oral HPV.

Results

A total of 214 of 334 WLWH had sufficient DNA for analysis at all three anatomical sites and were included in analyses. Cervical, oral, and anal high-risk (hr) HPV prevalence were 28.0%, 3.7% and 39.3%. Most frequent i) cervical, ii) oral and iii) anal hrHPV genotypes were i) hrHPV58 (8.4%), 52 (5.1%), 16 (5.1%) and 51 (5.1%); ii) 52 (1.4%) and iii) 51 (9.3%), 58 (8.9%), 16 (7.0%) and 18 (7.0%). Among present cervical, oral, and anal hrHPV genotypes, 6.7%, 12.5% and 17.9% were targeted by the 2-or 4-valent HPV vaccines, whereas 50.0%, 50.0% and 42.9% of hrHPV genotypes were covered by the 9-valent HPV vaccine. Anal HPV infection was predicted by cervical HPV infection (adjusted OR 4.47 (95%CI 2.25–8.89)).

Conclusion

Cervical and anal HPV infection were highly prevalent in WLWH. Non-16/18 hrHPV genotypes were predominant at all anatomical sites. Almost half of all hrHPV infections at the three anatomical sites could have been prevented by childhood/adolescent vaccination with the 9-valent HPV vaccine.

Background

Five percent of the world’s cancer burden is attributable to human papillomavirus (HPV) infection [1], and people living with HIV (PLWH) have elevated risk of HPV related cancers at different anatomical sites, compared to their HIV-negative peers [2], [3], [4]. Especially increased risk of HPV-related cervical cancer (CC) [2], [5], [6], [7], [8], [9], oropharyngeal cancer (OPC) [5], [10], [11], and anal cancer (AC) [5], [12] has been reported [2], [5], [6], [7], [8], [9]. Whereas HPV is the

Objectives

The aim of the present study was to assess the prevalence, distribution and concordance of cervical, oral, and anal HPV in WLWH in Denmark. Furthermore, we aimed at identifying predictors of oral and anal HPV.

Setting

Denmark has a population of 5.7 million [29] and an estimated HIV prevalence among adults of 0.1% [30]. Medical care, including ART, is tax-paid and provided free-of-charge to all PLWH [22]. Treatment of HIV is restricted to eight specialized medical centres. Six of these centres participated in the SHADE [22]. PLWH are visiting outpatient clinics at intended intervals of 3–6 months [31]. During the study period, HIV guidelines recommended cervical cytology twice the first year after HIV

Characteristics of the cohort

A total of 334 WLWH consented for study participation [22]. Of 326 cervical, 327 oral and 327 anal samples; 295 (90.5%), 273 (83.5%) and 270 (82.6%) yielded sufficient DNA for HPV assessment, leaving 214 (64.1%) participants with conclusive HPV test results from all three anatomical sites. Baseline characteristics of the 214 included WLWH are presented in Table 1. Median age at inclusion was 42.9 years (IQR 36.3–48.4) and median duration of HIV was 11.0 years (IQR 5.3–17.1). Overall, 95.3% of

Discussion

In this multicentre, cross-sectional cohort study of WLWH in Denmark, more than half of WLWH were concurrently cervical and anal HPV positive, and a large proportion presented with multiple anogenital HPV infections. A correlation between cervical and anal hr- and lrHPV was observed and cervical HPV infection predicted anal HPV infection. Non-16/18 hrHPV genotypes were predominant at all anatomical sites. Almost half the present hrHPV genotypes would have been covered by the 9-valent HPV

Conclusion

Systematically generated evidence of HPV infection in cohorts of PLWH can help shape primary and secondary HPV related cancer prevention. Here we present data from a Danish cohort of WLWH, demonstrating that more than half had cervical and anal HPV infection with a large proportion presenting with multiple, concurrent anogenital HPV infections. Non-16/18 hrHPV genotypes were predominant, which renders the 2- and 4-valent HPV vaccines less effective than the 9-valent HPV vaccine. Regarding

      Because of the design of the Cobas 4800 system, we were unable to further delineate the genotypic distribution for the patients who tested positive for ohrHPV. A recent study reported that HPV51 and HPV58, followed by HPV16 and HPV18, were the most prevalent hrHPV serotypes identified in a cohort of 214 women living with HIV in Denmark.20 In another study, HPV51 and HPV16 were reported as the most frequent anal hrHPV serotypes identified among 151 women living with HIV in Montreal, Quebec, Canada, with an infection rate of 29% and 31%, respectively.21

      Low oral HPV viral copy numbers might be missed depending on the sensitivity of the assay.[22] The ability to estimate rates of HPV type-specific acquisition and clearance is limited by the rarity of oral HPV infection.[23] Standardizing methods of oral sample collection and HPV detection would ensure comparability between future oral HPV studies.[24]

      The prevalence of CIN lesions (18.5%) among WLHIV in this study was very similar to that reported in a study in HIV-negative women at a colposcopy clinic in Brazil (18.2%).14 However, the prevalence of CIN among women who reported more than 50 partners over their lifetime in our study was significantly higher (33%), and even higher than women with CD4 < 200/mm³ (42%), although HIV-associated immunosuppression is known to alter the relative carcinogenicity of HR-HPV types.27 A high prevalence of prior STIs (59.2%) was found in this study at a rate similar to that found in a study in the city of São Paulo, Brazil, in which the prevalence of was STIs around 61% in a group of women living with AIDS.12
