Аннотация
The performance of two different EM techniques applied for the detection of Epstein-Barr Virus (EBV) in oral hairy leukoplakia (HL) was assessed, i.e. the conventional two-step method of negative staining (CNS) and negative staining after Airfuge enrichment (ANS). Scrape specimens from the lateral borders of tongue of 66 HIV-positive patients with or without HL, of 3 patients with infectious mononucleosis and of 10 HIV-negative patients were evaluated. While CNS resulted in virus detection only in 25% of clinically diagnosed HL cases, EBV was detected by ANS in 85% of clinically suspected cases of HL. Scrape specimens of individuals negative for HIV were negative in EM while 2 of 3 mononucleosis patients were positive without clinical evidence for HL. Due to this high sensitivity the method of negative staining after Airfuge enrichment appears to be useful in the diagnosis of HL. The finding of EBV in clinically normal oral mucosa in HIV-seropositive individuals is interesting and indicates that EBV expression may precede the clinical appearance of HL.
