Abstract：
:The present study on genetic diversity of human papillomaviruses in women infected by HIV in Brazil describes the frequency, the genotypes, and five new variants of HPV. One hundred fifty cervical smears of HIV-positive women were subjected to cytological examination, and the DNA samples obtained were assayed by MY09/MY11 amplification, followed by RFLP typing. The overall HPV-DNA-positive rate was 42.7%. One hundred twenty-two samples (81.3%) had benign cellular alterations or normal cytological results, and HPV DNA frequency among them was 30.3%. Otherwise, 96.4% of samples with altered cytology were positive for HPV DNA. A high diversity of genotypes was observed. HPVs-16 and 81 were the most prevalent (14.1%) and were followed by HPVs 52, 35, 62, 33, 53, 56, 66, 70, 18, 58, 6b, 11, 31, 39, 40, 61, 71, 32, 54, 59, 67, 68, 85, and 102. Five new variants of the high-risk HPVs 18, 33, 53, 59, and 66 were detected. Possible associations between the detection of HPV genotypes and the cytological classification, HIV viral load, CD4 count, and antiretroviral treatment were also examined. We observed that a high proportion of HIV-infected women are infected with HPV and may carry oncogenic genotypes, even when cytological evaluation shows normal results.
