Chemical Analysis of Human Breath A Means to Assess Pathology in Cystic Fibrosis and other Diseases

The chemical composition of human breath holds a §wealth of information regarding health. Although §the clinical measurement of chemicals in breath is §currently used in the diagnosis and treatment of §heartburn, due to H. pylori infection, and §g.i. problems, due to malabsorption, §further application of the technique has been §hindered by a lack of adequate §analytical methods. This work presents a review of §current applications of breath analysis. Following §the review, a discussion of the genetic disorder §cystic fibrosis (CF) is given, which includes a §description of the biological origins of CF as well §as the potential of breath analysis in its §treatment. This work then outlines several studies §carried out at the University of California, Irvine, §under the supervision of Dr. Donald Blake, Dr. Dan §Cooper, and Nobel Laureate Dr. F. Sherwood Rowland. §These studies were aimed at characterizing the §chemical composition of breath using a state-of-the-§art form of chromatography. An important result of §these studies was the discovery of carbonyl sulfide §as a promising trace biomarker of pulmonary function §in the breath of individuals with CF.
