Despite advances in immunosuppressive drugs, long-term success of liver transplantation is still limited by the development of chronic liver allograft dysfunction. Although the exact pathogenesis of chronic liver allograft dysfunction remains to be established, there is strong evidence that chemokines are involved in organ damage induced by inflammatory and immune responses after liver surgery....

Although survival after lung transplantation has improved significantly during the last decade, chronic rejection is thought to be the major cause of late mortality. The physiologic hallmark of chronic rejection has been a persistent fall in forced expiratory volume in 1 second associated with an obstructive ventilatory defect, for which the term bronchiolitis obliterans syndrome (BOS) was defi...

The introduction of ex vivo lung perfusion (EVLP) in the practice of lung transplantation has allowed the reconditioning of the marginal grafts and their conversion into transplantable grafts. In addition, EVLP can provide a platform for the application of various preventive measures to decrease the incidence of post-transplant complications. While the Toronto team targets the attenuation of th...

We have recently recognized humoral rejection (HR) in lung allograft recipients and its association with acute and chronic graft dysfunction. We have shown that C4d, a stable marker of classic complement activation, is deposited in lung allografts, correlating with clinical rejection and parenchymal injury. The antigenic target may be endothelium in the setting of recurrent acute rejection whil...

Background: Bronchiolitis obliterans syndrome (BOS) and restricted allograft (RAS) are two distinct phenotypes of chronic lung dysfunction (CLAD) in transplant (LTx) recipients.  Contrary to BOS, RAS can radiologically present with a pleuroparenchymal fibroelastosis (PPFE) pattern. This study investigates ultrasound (LUS) identify potential surrogate markers radiological PPFE patter...

Chronic lung allograft dysfunction (CLAD) is, in one sense, a term without a true consensus definition, although its common usage in the field of lung transplantation implies a base understanding throughout the community that it describes a lung allograft that does not work (well) [1]. There appears to be general agreement that CLAD most commonly occurs in a time-dependent fashion after transpl...
