Study summary

Lung transplantation is the ultimate treatment for end stage lung diseases. Survival after lung transplantation is limited mainly due to the development of chronic allograft dysfunction (CLAD). Both acute cellular rejection and primary grade dysfunction (PGD) have been associated with the development of CLAD. In this study we will investigate multiple prognostic factors that influence long term survival after lung transplantation with a specific interest in PGD, acute rejection and the development of CLAD.

Read the detailed description

At specific time points (according to protocol) exhaled breath, blood specimens, bronchoalveolar lavage and biopsies will be collected. These will be analyzed in an attempt to identify possible biomarkers that will predict the development of PGD and/or CLAD.

Inclusion criteria

  • all lung transplant recipients > 18 years signed ICF ( form)

Exclusion criteria

Exclusion Criteria:

  • none
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. identify prognostic biomarkers in blood, bronchoalveolar lavage and exhaled breath that will determine long term survival after human lung transplantation.

    death

    Time frame: up to 520 weeks

Secondary outcomes

  1. Secondary objectives are obtaining information on the development of (Primary graft development) PGD in relationship to respiratory viruses, genetic profile and exhaled breath in patients and (if possible donors) after human lung transplantation.

    PGD

    Time frame: from transplantation till 72 hours after surgery
