alpha 1-antitrypsin (alpha 1-A.T.) phenotypes were determined in 55 patients with rheumatoid arthritis (R.A.), 33 patients with R.A. and either obstructive airways disease or recurrent chest infections, 49 patients with fibrosing alveolitis (F.A.), 22 patients with R.A. and F.A., and 200 healthy controls.
We suggest that IL-8 is a key factor in the pathogenesis of fibrosing alveolitis and that the poorer prognosis of CFA compared with FASSc is related to higher levels of IL-8 within the lower respiratory tract.
Interestingly, atypical alveolar epithelium, which associates with asbestosis and idiopathic fibrosing alveolitis and is considered to be a precursor lesion for lung cancer, expressed the Cox-2 protein.

To search for single-nucleotide polymorphisms in the interleukin-8 (IL-8) and IL-8 receptor CXCR-1 and CXCR-2 genes, and to compare their distribution among patients with systemic sclerosis (SSc) with fibrosing alveolitis (FASSc) or without fibrosing alveolitis (NFASSc), or patients with cryptogenic fibrosing alveolitis (CFA), and normal healthy subjects.
Fibrosing alveolitis (FA) is characterized by persistent inflammation and elevated production of tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1beta), and interleukin-1 receptor antagonist (IL-1ra) in the lung.
These data suggest IL-1RN (+2018) allele 2 and TNF-A (-308) allele 2 confer increased risk of developing FA and, therefore, that unopposed IL-1beta and/or excessive TNF-alpha may play a pathophysiologic role in this condition.

Using a candidate gene approach, we found a heterozygous exon 5 + 128 T-->A transversion of SFTPC in a large familial pulmonary fibrosis kindred, including adults with usual interstitial pneumonitis and children with cellular nonspecific interstitial pneumonitis.
We found that the distribution of PAI-1 genotypes in the idiopathic interstitial pneumonia population was similar to that of a large control population.
