Detección de Virus Papiloma Humano en el fluido gingival de pacientes con inmunodeficiencia humana y enfermedad periodontal

evidence suggests that viruses may be involved in the activation of periodontal disease, allowing the overgrowth of periodontal pathogens. the purpose of the present study was to detect the presence of human papillomavirus (hpv) in gingival crevicular fluid (gcf) in hiv+ venezuelan patients with periodontal disease. we evaluated gcf samples from 20 hiv+ patients with periodontal disease from the infectious disease center, faculty of dentistry, central university of venezuela, and were clinically examined to establish their periodontal conditions, 13 under haart (antiretroviral therapy) and 7 without haart. seven seronegative patients with chronic periodontitis and 7 seronegative patients, without periodontal disease were included. dna extraction was performed, the consensus primers my09 and my11 for the hpv l1 region were used for pcr amplification. genotipification was made for the 6, 11, 16, 18, 31 and 45 genotypes. hpv were detected in 46% of hiv+ patients under therapy. the cd4 cell counts in the hpv+ patients were not significantly different from the hpv-group. the viral load in the hpv+ group was significantly higher (200,470 ± 324,244 copy/ml) than in the hpv- patients (10,246 ± 23,805 copy/ml). genotypes 6 and 11 were observed in the hpv positive samples, of which 4/6 (66.6%) presented coinfection with both types. no significant differences in the periodontal conditions were observed between patients with hpv-hiv infection related to patients with only hiv. hpv was detected only in the gingival crevicular fluid of hiv+ patients under haart independently of the periodontal conditions.
