    Abstract:
    BACKGROUND: Worldwide, human papillomavirus (HPV) 16 and 18 represents 70% of high-risk (HR) HPV found in cervical cancer. However HIV-positive women are more frequently infected by HRHPV other than HPV 16 or 18 (OHR). We aimed to analyse the HRHPV genotype distribution in a cohort of HIV-positive women and to estimate the potential protection offered by the different HPV vaccines. METHODS: HRHPV genotypes by PCR and cytology were assessed in cervical samples from 508 HIV-positive women prospectively followed in Brussels. RESULTS: Women characteristics were as follows: African origin (84%), median age 42 years, median CD4 T 555/μl, 89% under combined antiretroviral therapy and 73% with HIVRNA less than 20 copies/ml. HRHPV prevalence was 23% (116/508): 38% had abnormal cytology, 76% carried OHR without HPV 16 or 18 and 11% had concomitant infection by OHR and HPV 16 or 18. The most frequent HRHPV were HPV52 (19.8%), HPV18 (14.6%), HPV31/35/51/58 (12.1% each), HPV56 (9.9%) and HPV16 (9.5%). Less than 30% of women had their HRHPV genotypes included in the bivalent or quadrivalent vaccines against HRHPV 16 and 18; however, 79% had their HRHPV covered by the ninevalent vaccine against HRHPV 16/18/31/33/45/52/58. CONCLUSION: The HRHPV genotypes distribution found in these women living in Europe with a successfully treated HIV is similar to the one found in Central Africa with HRHPV other than HPV16 or 18 retrieved in 87%. In this population, the bivalent or quadrivalent vaccines could offer protection in only 30% of women; however this protection could be extended up to 80% with the ninevalent vaccine.
