Facts and controversies in the classification of idiopathic interstitial pneumonias. V Poletti, M Kitaichi. Sarcoidosis Vasc Diffuse Lung Dis 2000 Oct;17(3):229-238. "Idiopathic interstitial pneumonias are defined from the pathological point of view as non granulomatous intralobar inflammatory and fibrotic processes involving the alveolar walls. More than thirty years ago Liebow and Carrington pioneered the notion that morphological characteristics could be used with benefit in separating the different entities found in this group, which present with typical, but not pathognomonic clinical features. In the mid-1980s some entities, including giant cell interstitial pneumonia (GIP) and lymphocytic interstitial pneumonia (LIP), were removed from this group and considered as peculiar forms. In the early 90s the concept of cellular or nonspecific interstitial pneumonia was reconsidered, leading to an in depth revision of various types of interstitial pneumonia of unknown etiology. The histological pattern observed in patients with idiopathic pulmonary fibrosis is now referred to as usual interstitial pneumonia (UIP). Other entities that have been revised during the last ten years are desquamative interstitial pneumonia/alveolar acute interstitial pneumonia (DIP/AMP), respiratory bronchiolitis-interstitial lung disease (RB-ILD), acute interstitial pneumonia (AIP), cryptogenic organizing pneumonia (COP) and nonspecific interstitial pneumonia (NSIP). This paper provides a detailed description of pulmonary disorders which have been included in the new classification systems of idiopathic interstitial pneumonias..."

Eur Respir J 1997 Sep;10(9):2040-2045. 43 patients with IPF, 7 collagen vascular disease related interstitial pneumonitis, 22 sarcoidosis, 17 emphysema, 35 normal controls. CMV and EBV were elevated in IPF and CVD-IP versus others.

No EBV found in any CFA patients, with or without systemic sclerosis; patients with other pulmonary diseases; or normal lung.
Wangoo - Thorax 1997 abstract / PubMedThe detection of Epstein-Barr virus DNA in lung tissue from patients with idiopathic pulmonary fibrosis. JP Stewart, JJ Egan, AJ Ross, BG Kelly, SS Lok, PS Hasleton, AA Woodcock. Am J Respir Crit Care Med 1999;159(4):1336-1341. 27 IPF patients vs 28 controls, positive by both IHC + PCR, p=0.001. "The presence of IgA antibodies to EBV VCA has been correlated with a diagnosis of IPF. This marker is an indicator of active EBV replication at an epithelial surface. Our previous and current finding of active EBV replication therefore corroborates the IgA serology, and this study confirms previous immunohistochemical observations. EBV antigens and DNA in the lower respiratory tract were significantly associated with a diagnosis of IPF." They also note that formalin fixation of samples can cause protein degradation and thus loss of detection in samples. Re Wangoo et al: "The inability of Wangoo and colleagues to identify any EBV DNA in lung tissue is perhaps more surprising. Even if EBV were not associated with IPF one would expect to find a low-level background of EBV DNA in lung tissue simply because of the blood volume in this organ."
