A 2-year Review of the Diagnostic Performance of Serum and Bronchoalveolar Lavage Galactomannan Testing in Lung Transplant Recipients in a National Heart and Lung Transplant Centre.

Background: The 2015 International Society for Heart and Lung Transplant (ISHLT) fungal guidelines recommend the use of bronchoalveolar lavage (BAL) galactomannan over serum galactomannan for the diagnosis of invasive aspergillosis (IA) in lung transplant (LTx) recipients, based on limited evidence. Galactomannan testing is costly.

Methods: A single-center, retrospective cohort study reviewing all 814 serum and BAL galactomannan samples received from 184 LTx recipients in our center between 2021 and 2022 and assessing their diagnostic performance in the diagnosis of IA.

Oesophageal stasis is a risk factor for chronic lung allograft dysfunction and allograft failure in lung transplant recipients.

Background: Morbidity and mortality in lung transplant recipients are often triggered by recurrent aspiration events, potentiated by oesophageal and gastric disorders. Previous small studies have shown conflicting associations between oesophageal function and the development of chronic lung allograft dysfunction (CLAD). Herein, we sought to investigate the relationship between oesophageal motility disorders and long-term outcomes in a large retrospective cohort of lung transplant recipients.

Donor and recipient human leukocyte antigen-G polymorphisms modulate the risk of adverse immunologic events following lung transplantation.

The long-term benefits of lung transplantation (LTx) are limited by pathogenic alloimmune responses that drive injury, inflammation, and chronic dysfunction. Human leukocyte antigen-G (HLA-G) plays a key role in the modulation of these pathways. This study assesses the impact of the HLA-G genotype on immunologic risk and survival following LTx.
