title: Clinical and laboratorial study of HPV infection in men infected with HIV.
abstract: OBJECTIVE
  To determine the prevalence of precursor lesions of penile cancer, to establish the concordance of diagnostic techniques (PCR, Hybrid Capture (HC) and peniscopy with acetic acid 5%) in the diagnosis of Human Papilloma Virus (HPV) of the penis of men infected with HIV and to evaluate the influence of the immune status.
  
  
  RESULTS
  276 men were studied, with a median age of 34.6 years. Prevalence of High Risk HPV, Low Risk HPV and infection with both, according to HC, was 43%, 32% and 22%, respectively. PCR showed 50% of positivity for HPV DNA. Peniscopy was positive in 27% of individuals. Peniscopy showed good specificity and low sensitivity for the detection of penile HPV, and low concordance with PCR. Men with white lesions had a 3.6 higher relative risk of positivity for HPV. The most common clinical lesion observed was vegetation, identified in 29% of patients. PCR and HC techniques showed high sensitivity for HPV DNA and there was an excellent correlation between them. Immunosuppressed individuals with CD4 < 200 cells/mm(3) had the highest prevalence of premalignant lesions that were observed in 10% of the studied individuals.
  
  
  CONCLUSIONS
  Peniscopy was important for identification and treatment of subclinical lesions. PCR and HC techniques were sensitive methods for the detection of HPV DNA with high concordance. Severely immunosuppressed individuals showed a higher prevalence of pre-malignant lesions of the penis.
