Summary

Haemopoietic stem cell transplantation (HSCT) has become a major life-saving treatment for many haematological conditions, mostly malignancies.

However, there are lots of potential complications that hinder the long-term success of HSCT, in which bronchiolitis obliterans syndrome (BOS) is one of such serious complications. Basically, BOS represents a form of graft-versus-host immunological damage of small airways (bronchioles), leading to progressive narrowing of small airways and thus obstructive lung function abnormalities. With progressive loss of lung function in BOS, patients after HSCT can be complicated by intractable respiratory failure that results in mortality. Up until now, there is still no reliable way to accurately predict or detect BOS early to allow pharmacological interventions.

Therefore there is intense interest in the search for biomarkers that can help to predict the occurrence of BOS after HSCT. Apart from biomarkers (e.g., cytokines) in blood, there has been recent development in the sampling of airway lining fluid by a non-invasive method, i.e., collection of exhaled breath condensate (EBC). In airway diseases such as asthma or chronic obstructive pulmonary disease, EBC has been found to have various cytokines which can serve as potential biomarkers of disease activity. Since BOS is largely a small airway disease, it becomes logical to investigate the profile of biomarkers in EBC as predictors for BOS after HSCT.

Therefore this study has been designed to look into the role of biomarkers in blood and EBC in early detection of BOS after HSCT.
