ABSTRACT
BACKGROUND:
The main causes of early respiratory failure after lung transplantation include primary graft dysfunction (PGD), acute rejection, and infection. This report describes a case of unclear early respiratory failure after bilateral lung transplantation for extensive COVID-19-induced acute respiratory distress syndrome (ARDS).METHODS:
We reviewed the patient file to investigate the course of the functional decline and evaluate reasons for early graft failure. Analyzed data included crossmatching results, biopsy results, HLA antibodies testing, bronchoalveolar lavages, respiratory parameters, and medications.RESULTS:
After an initial excellent early postoperative course, the patient developed progressive respiratory failure, making re-implantation of extracorporeal membrane oxygenation (ECMO) support necessary. An extensive diagnostic workup revealed no signs of infection or rejection. Because the patient showed no signs of improvement with any treatment, lung-protective ventilation with the intermittent prone position was initiated. The patient's respiratory situation and bilateral opacities slowly improved over the next few weeks, and ECMO support was eventually discontinued.CONCLUSION:
With no evidence of PGD, rejection, or infection, recurrent ARDS caused by a systemic immunologic process was seen as the only plausible cause for the patient's respiratory failure after lung transplantation. The fact that ARDS can develop extrapulmonarily, without direct viral or bacterial damage, makes us conclude that the preceding systemic activation and recruitment of immune cells by the primarily injured lung could potentially lead to the recurrence of ARDS even if the injured organ is removed.
