Rapid in situ hybridization for the diagnosis of latent Epstein-Barr virus infection.
Latent Epstein-Barr virus (EBV) infection is associated with a variety of malignancies. Rapid in situ hybridization techniques have been described for various lytic viral infections because of limited gene expression. However, EBERS (Epstein Barr early RNAs) are expressed in abundance in tumour cells which are latently infected with EBV. We have targeted these transcripts in a rapid (3 h) in situ hybridization assay fo the detection of latent EBV in clinical specimens, including formalin-fixed paraffin-embedded material. EBER RNA was detected in control cell lines which have two copies of the EBV genome and in paraffin-embedded biopsy specimens from patients with nasopharyngeal carcinoma, EBV-associated Hodgkin's disease, Burkitt's lymphoma and post-transplant lymphoma. The technique did not detect EBER RNA in oral hairy leukoplakia, a pathologic process previously characterized as associated with lytic EBV infection. The sensitivity, specificity and rapidity of this technique make it ideal for the diagnostic detection of EBV in latently infected clinical specimens.
