Abstract
The subject invention is directed to the measurement of elastic fiber breakdown products in human sputum obtained from patients with emphysema and other lung diseases. Measurement of elastic fiber breakdown products may be used to monitor the progression of lung disease or to assess the efficacy of a treatment for lung disease. Such breakdown products are associated with lung injury resulting from degradation of lung elastic fibers. This process may occur in emphysema and other inflammatory disease of the lung where excess amounts of elastase are secreted by inflammatory cells. The methods for measuring elastin breakdown products in certain tissue fluids (i.e. blood, urine, bronchoalveolar lavage fluid) are well known to the art but have not been previously applied to sputum samples. The use of sputum has several advantages over other fluids, including greater specificity and ease of procurement.
