- W2002176103 abstract "Oral hairy leukoplakia (OHL) is a lesion associated with a compromised immune system, and its diagnosis is determined by the demonstration of the presence of Epstein-Barr virus (EBV) in lesional tissue. The purpose of this article was to develop a simple technique to help the diagnosis of OHL, using PCR as an alternative technique to evidence EBV in scrapings. DNA samples were obtained by scraping the lateral border of the tongue of 38 adult patients: 29 HIV-positive patients (4 with clinical evidence of OHL; 4 with history of OHL, but without lesion at the moment the samples were collected; and 21 without clinical evidence of OHL), and 9 healthy volunteers for the control group. DNA was extracted from scrapes and amplified by PCR using specific primers for EBV. Of the 29 cases of HIV-positive patients, 22 (75.86%) were positive for EBV: 2 patients with clinical evidence of OHL, 4 patients with history of OHL, but without lesion at the moment the samples were collected, and 16 patients without clinical evidence of OHL. In the control group, samples of 5 (55.56%) healthy volunteers presented amplification for EBV. We concluded that the use of PCR in oral scrapes suggests a high sensitivity but low specificity for the diagnosis of OHL." @default.
