Background We previously reported that plasminogen activator inhibitor 1 (PAI-1) was
upregulated in human asthmatic airways and promotes airway fibrosis in an allergen-
challenged murine model of asthma. Objectives To examine whether elevated plasma levels
of PAI-1 are associated with poor lung function in asthmatic patients. Methods Five hundred

completed the baseline protocol between January 24, 2004, and July 30, 2005. Of these …
