Is obliterative bronchiolitis in lung transplantation associated with microvascular damage to small airways?

0

GROUND: Acute rejection, a vascular-based disorder, has been identified as the major risk factor for obliterative bronchiolitis (OB), an airway-based pathology. This study investigated the hypothesis that changes to the microvascular blood supply of small airways were associated with the development of OB, thus providing a possible link between an acute vascular insult (acute rejection) and chronic airway changes (OB). METHODS: Microvasculature of 695 small airways (99 patients) was assessed in post-mortem lung allograft specimens using monoclonal antibodies for von Willebrand factor and CD31. Group A consisted of 343 small airways from 58 patients with no evidence of OB. The remaining 41 patients had histological evidence of OB in some of their small airways and grouped as B, C, and D with some patients contributing to all three groups ie, their lung specimen had some small airways which were completely obliterated with OB, some airways which were partially obliterated and some small
