摘要
BackgroundAlthough HPV emerged as a crucial carcinogenic and prognostic biomarker in head and neck cancer, and considering the increase in HPV-associated oral lesions (HPV-OLs) in HIV individuals, molecular information about HPV-OLs is scarce; thus, our aim was to determine viral loads in HPV-OLs from HIV/AIDS individuals. MethodsHIV/AIDS subjects with HPV-OL were included in this cross-sectional study. Following informed consent, biopsies were obtained. HPV detection and typing were carried out by PCR and sequencing (MY09/11, GP5+/6+). HPV-13 and HPV-32 loads were determined by a high-resolution melting assay. For statistical analysis, X-2, Fisher's exact, and Mann-Whitney U tests were applied, using SPSS software (v.23). ResultsTwenty-nine HIV subjects (median age 38years, 93% males) were included. Most were AIDS individuals (72.4%) under HAART (89.7%). Twenty-two (75.9%) participants had more than one HPV-OL (four with florid presentations), mostly multifocal epithelial hyperplasia (62%), being HPV-13 (26%) and HPV-32 (31%) the most frequent types. HPV load was higher in individuals with multiple HPV-OLs than in solitary lesions (4.9 vs. 3.2 Log(10) copies/ml, p=.090) and in HPV-32(+) than in HPV-13(+) (8.3 vs. 6.4 Log(10) copies/ml, p=.014). ConclusionsMultiple HPV-OLs showed high HPV loads, possibly indicating transcriptional activity of the virus; however, in the HIV setting, the individual and local immunological response could be the key process.
