“…In Brazil, a study conducted in Pará state reported HPV-18 to be the most frequent type with 12.5% prevalence. 6 High rates of HPV multiple infections in clinically healthy oral mucosa was also found by Terai et al 13 and Machado et al 3 with prevalence of 56.7% and 42.8%, respectively.…”

“…This rate is similar to the one reported by Terai et al 13 in Japan (81%), but substantially different from those reported worldwide with a lower prevalence of the virus. 6,7,12 Little information is available regarding the prevalence of oral HPV infection in the Brazilian population. A study conducted with undergraduate students from a University in the state of Rio de Janeiro did not detect any virus in samples of healthy oral mucosa.…”

“…2 However, authors from a different state found a prevalence of 24.1% in their population. 6 Another study reported the presence of HPV in 54% of women with clinically healthy oral mucosa but whose sexual partners presented HPV-associated genital lesions. 14…”

“…5 In São Paulo state, Brazil, Tristão et al 1 described a prevalence of 23.2% HPV in healthy oral mucosa and associated the presence of the virus with regular oral sex. Similarly, in Pará state, Brazil, Araújo et al 6 reported 24.1% positive oral samples for HPV-DNA.…”

“…Changes in male and female sexual behaviors may be associated with the increased prevalence of HPV infection in oral cavity recently reported. 6 However, HPV oral infection is also transmitted by autoinoculation of existing genital or skin lesions and may also be transmitted vertically from the mother to the fetus. 2,7 The detection of the virus in the epithelium of clinically healthy oral mucosa does not yet allow the accurate inference of its role in oral carcinogenesis.…”

Variable rates of HPV infection have been reported in healthy oral mucosa worldwide. The main objective of this study was to detect and genotype HPV infection in users and nonusers of drugs with clinically healthy mucosa from the Northeast Brazil. Samples from 105 patients were amplified using the primers MY09/MY11 and GP5+/GP6+, and genotyping was performed by multiplex-PCR for HPV-6/11, 16 and 18. A total of 81.9% samples were positive. Among drug users, 84.5% presented the virus and 20.4% showed multiple infections. Among non-drug users, 78.7% were positive and 13.5% had multiple infections. Limited information is available on oral HPV in Brazilian population, especially for drug users, and our results showed higher HPV infection rates in both users and nonusers of drugs. More studies and researches focused on drug users including factors like sexual behavior, nutrition and cultural habits are necessary to enhance the comprehension of this relationship, and develop preventive strategies.
