BACKGROUND AND AIM OF THE WORK: Idiopathic Pulmonary Fibrosis/Usual Interstitial Pneumonia (IPF/UIP) is a diffuse and progressive lung disease whose pathogenesis is incompletely understood. Recently, the presence of Herpesvirus-specific DNA was detected in the large majority of cases of a series of IPF/UIP and other lung interstitial diseases. We have therefore tested our own IPF/UIP series for the presence of HHV-8 and EBV proteins. METHODS: We used a variety of sensitive technologies including immunohistochemistry with NCL-HHV8-LNA and EBV-LMP1 antibodies, as well as of EBV RNA (EBER) by in-situ hybridisation; the presence of HHV-8 and EBV DNA was also investigated by means of PCR and subsequent analysis using a microfluidic apparatus. RESULTS: Despite the good sample quality, immunohistochemical, in-situ hybridisation and PCR results were negative for both EBV and HHV-8. CONCLUSIONS: We conclude that EBV and HHV-8 are not involved in the pathogenesis of IPF/UIP.
