Relationship to Deployment on Sarcoidosis Staging and Severity in Military Personnel

Description
Summary:Abstract Introduction Ongoing studies are investigating the potential link between deployment to Operation Iraqi Freedom and Operation Enduring Freedom and relationship to increases in pulmonary disease. While increases in certain diseases such as asthma and airway hyperreactivity are well established, data on other chronic pulmonary diseases such as sarcoidosis have not been defined. Material and Methods A retrospective chart review was conducted of all active duty military personnel diagnosed with sarcoidosis from 2005 to 2010. Deployment dates and locations were obtained through the Armed Forces Health Surveillance Branch. Electronic medical records were reviewed to determine the following parameters: dates of diagnosis, temporal relationship of diagnosis and deployment, symptoms (pre- and/or post-deployment), spirometry, diffusing capacity, radiographic staging, and treatment course. Pulmonary sarcoidosis incidence rates were estimated using International Classification of Diseases (ICD-9) coded medical encounter data from the Defense Medical Surveillance System and compared between Army and nonArmy personnel, as well as between ever-deployed and never-deployed personnel. Results A cohort of 478 Army soldiers was identified with sarcoidosis based on ICD-9 codes and individual review of the medical records. The cohort was 80% male. 38.7% of soldiers with sarcoidosis never deployed. 11.7% were diagnosed prior to deployment, and 50.2% were diagnosed postdeployment. The diagnosis of sarcoidosis was established with a tissue diagnosis in 68% of the deployed cohort. Overall differences in spirometry were not identified. Obstructed spirometry was similar in all deployment groups (never, pre, and post) at 9.2%, 15.8% and 8.7%, respectively. Restrictive patterns based on total lung capacity (
