The role of interleukin-8 in interstitial pneumonia.

Objective: A variety of inflammatory cells accumulate in the lungs of patients with interstitial lung disease. The potential for IL-8 to be released from these cells into the lungs of patients with idiopathic interstitial pneumonia (IIP), interstitial pneumonia with collagen vascular disease (IP-CVD), sarcoidosis (SAR) and hypersensitivity pneumonitis (HP) was investigated.

Methodology: IL-8 levels were assessed by enzyme-linked immunosorbent assay in BAL fluid and serum, and the expression of IL-8 in the lungs of these patients was evaluated by immunohistochemistry.

[Clinical evaluation of rounded atelectasis induced by exposure to asbestos].

We encountered 15 patients with rounded atelectasis induced by exposure to asbestos from 1992 to 1999. All patients were men whose ages ranged from 42 to 85 years, with a mean age of 64.2 +/- 11.
