Brief Summary:
The most effective treatment of hematologic malignancies and some benign hematological diseases is allogeneic stem cell transplantation therapy. Pulmonary complications can occur after allogeneic stem cell transplantation. And these complications effect mortality and morbidity in these patients. In this study we want to investigate the use of exhaled breath condensate (EBC) collection which is a simple and completely noninvasive method. By this way we hope to detect pulmonary complications early. EBC, has been implicated in the pathophysiology of inflammatory airway diseases such as cystic fibrosis, asthma, chronic obstructive pulmonary disease (COPD) and bronchiectasis. EBC, has not been investigated before in patients who underwent stem cell transplantation.

Condition or disease Intervention/treatment
Exhaled Breath Condensate Other: Exhaled breath condensate

Study Type : Observational
Estimated Enrollment : 80 participants
Observational Model: Case-Only
Time Perspective: Prospective
Official Title: "Exhaled Breath Condensate" in Allogeneic Stem Cell Recipients and Value in Follow-up
Study Start Date : December 2014
Estimated Primary Completion Date : December 2015
Estimated Study Completion Date : April 2016

Group/Cohort Intervention/treatment
EBC level
Exhaled breath condensate level of allogeneic stem cell transplantation patients
Other: Exhaled breath condensate
Breath condensate samples will be collected with a commercially available condenser (EcoScreen®, Erich Jaeger, Germany). Subjects will breathe through a mouthpiece and a two-way non-rebreathing value in which inspiratory and expiratory air were separated, and saliva was trapped. They will be asked to breathe at a normal frequency and tidal volume for 15 minutes while wearing nose clips, allowing collection of 1.5-2.5 mL of condensate. After collecting this, pH will be measured and the waste collection will be stored at -80 degrees. Then 8 isoprostane and nitrotyrosine will be measured collectively




Primary Outcome Measures :
  1. The pH level of exhaled breath condansate [ Time Frame: 2 years ]

Secondary Outcome Measures :
  1. The nitrotyrosine and 8-isoprostane levels of exhaled breath condansate [ Time Frame: 2 years ]
