Prior studies of this patient population have revealed that unexplained exertional dyspnea is the most common diagnosis despite an extensive evaluation. There is a concern that an occult disorder may be affecting this population. This study evaluated the role for bronchoalveolar lavage (BAL) fluid analysis in the evaluation of chronic deployment-associated dyspnea.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Materials and Methods<\/jats:title>\n                  <jats:p>Military personnel who reported chronic respiratory symptoms were evaluated as part of the Study of Active Duty Military for Pulmonary Disease Related to Environmental Deployment Exposures III study.

BAL cell-count percentages of macrophages, lymphocytes, neutrophils, and eosinophils were: 76.2\u2009\u00b1\u200917.0%, 16.3\u2009\u00b1\u200913.4%, 6.6\u2009\u00b1\u20098.9%, and 0.9\u2009\u00b1\u20093.2%, respectively. There was no clear differentiation between groups based on increases in lymphocyte counts (P\u2009=\u2009.640), although lymphocyte values were more elevated (21.4\u2009\u00b1\u200912.1%) in the interstitial lung disease category. Neutrophil counts (6.6\u2009\u00b1\u20098.9%) were elevated compared to the reported normal reference values and were increased in the isolated pulmonary function test abnormality (9.4\u2009\u00b1\u200911.6%), large airway disorder (10.0\u2009\u00b1\u20097.5%), miscellaneous (10.9\u2009\u00b1\u200920.2%), and obstructive lung disease (11.0\u2009\u00b1\u200915.6%) groups. Eosinophil counts were within normal limits (0.9\u2009\u00b1\u20093.2%) and showed no differences between groups (P\u2009=\u2009.545); asthma patients trended higher (1.6\u2009\u00b1\u20095.7%).
