Background:
HIV (+) patients have a higher risk of oral infections with high oncogenic risk HPV (HPV-HR).
Aim:
To determine the HPV genotypes in oral papillomatous lesions in HIV (+) patients and describe the associated factors.
Methods:
Eight adults HIV (+) subjects with papillomatous HPV lesions were studied. The lesions DNA was extracted and HPV genome and genotypes were detected by PCR and the commercial kit HPV 3.5 LCD-Array Kit (Chipron®) and associated factors were described.
Results:
63% of patients exhibited more than one HPV genotype and 75% of them exhibited at least 1 HPV-HR genotype. The most frequent genotype was HPV 52 (27%), followed by HPV 16 and 56 (18%). The mean CD4 T lymphocyte count in patients with at least one HPV-HR genotype was 330.6 cells/mm3.
Conclusions:
A higher frequency of multiple HPV infections was detected, including at least one high-risk genotype. The genotype HPV-AR 52 was the most frequent. The mean CD4 T lymphocyte count in patients with at least one HPV-HR genotype indicates moderate immunosuppression. It is required to increase the number of patients.
