exhaled breath condensate


Enrollment: 24
Study Start Date: January 2011
Study Completion Date: July 2014
Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts
Invasive pulmonary aspergillosis (IPA)
Patients with proven or probable invasive pulmonary aspergillosis (IPA) (EORTC/MSG criteria) or putative IPA (Blot et al. Am J Respir Crit Care Med 2012)
Controls
Patients without signs of infection.

Detailed Description:

Invasive pulmonary aspergillosis (IPA) is a life-threatening infection in immunocompromised patients. The poor prognosis of the disease is partly attributed to difficulties encountered with the diagnosis of this infection. Invasive sampling procedures are often precluded in these patients. In addition, conventional diagnostic techniques lack sensitivity. Recently there has been increasing interest in the investigation of the lungs by noninvasive means including measurement of biomarkers in exhaled breath (e.g. NO) and those found in the cooled and condensed exhalate,termed EBC. It has been demonstrated that a measurable fraction of the EBC in healthy subjects is derived from aerosolized airway lining fluid. The presence of biomarkers for IPA will be investigated in EBC of patients with IPA, compared to controls.
