An underrecognized phenotype of pulmonary emphysema with marked pulmonary gas exchange but with mild or moderate airway obstruction.

In patients with pulmonary emphysema and mild to moderate airflow limitation, one does not expect the features marked exertional dyspnea and hypoxemia as well as a profound decrease in diffusing capacity of the lung for carbon monoxide (DLCO). Here we describe this phenotype and its prognosis. From our database, we retrospectively selected cases associating emphysema, exertional breathlessness, O requirement at least upon exercise, forced expiratory volume in 1 sec (FEV) ≥ 50% predicted, and DLCO ≤ 50% predicted, without associated combined pulmonary fibrosis and emphysema, right-to-left shunt, or severe pulmonary hypertension.

Effect of antifibrotic agents on postoperative complications after lung transplantation for idiopathic pulmonary fibrosis.

Background: Antifibrotic agents (AFAs) are now standard-of-care for idiopathic pulmonary fibrosis (IPF). Concerns have arisen about the safety of these drugs in patients undergoing lung transplantation (LTx).

Methods: We performed a multi-centre, nationwide, retrospective, observational study of French IPF patients undergoing LTx between 2011 and 2018 to determine whether maintaining AFAs in the peri-operative period leads to increased bronchial anastomoses issues, delay in skin healing and haemorrhagic complications.

Risk of Bronchial Complications After Lung Transplantation With Respiratory . Results From a Monocenter Retrospective Cohort Study.

spp. are associated with respiratory infections in immunocompromised hosts. A link with bronchial complications after lung transplantation (LTx) has been suggested.

ECMO support as a bridge to lung transplantation is an independent risk factor for bronchial anastomotic dehiscence.

Background: Airway complications are frequent after lung transplantation (LT), as they affect up to 23% of recipients. The implication of perioperative extracorporeal membrane oxygenation (ECMO) support and haemodynamic instability has never been specifically assessed. The first aim of this study was to explore the impact of perioperative ECMO support on bronchial anastomotic dehiscence (BAD) at Day 90 after LT.

Bacteraemia Is Associated with Increased ICU Mortality in the Postoperative Course of Lung Transplantation.

We aimed to describe the prevalence, risk factors, morbidity and mortality associated with the occurrence of bacteraemia during the postoperative ICU stay after lung transplantation (LT). We conducted a retrospective single-centre study that included all consecutive patients who underwent LT between January 2015 and October 2021. We analysed all the blood cultures drawn during the postoperative ICU stay, as well as samples from suspected infectious sources in case of bacteraemia.

Patient-important outcomes in lung transplantation: A systematic review.

Background: Patient-important outcomes (PIOs) have emerged in respiratory medicine, in order to place the patient at the center of research. Mortality is a debated PIO in lung transplantation (LTx). The use of PIO in this specific setting has never been studied.

Acute worsening of native lung fibrosis after single lung transplantation for pulmonary fibrosis: two case reports.

Background: In patients receiving single lung transplantation for idiopathic pulmonary fibrosis, worsening of fibrosis of the native lung is usually progressive over time, with no significant effects on gas exchange.

Case Presentation: Here, we describe the cases of two Caucasian male recipients of single lung transplants for idiopathic pulmonary fibrosis, 65 and 62 years of age, who exhibited acute worsening of lung fibrosis after an episode of serious viral infection (cytomegalovirus primo-infection in one case and COVID-19 in the other). In both cases, along with opacification of the native lung over several days, the patients presented acute respiratory failure that required the use of high-flow nasal oxygen therapy.

Determinants of survival after lung transplantation in telomerase-related gene mutation carriers: A retrospective cohort.

Carriers of germline telomerase-related gene (TRG) mutations can show poor prognosis, with an increase in common hematological complications after lung transplantation (LT) for pulmonary fibrosis. The aim of this study was to describe the outcomes after LT in recipients carrying a germline TRG mutation and to identify the predictors of survival. In a multicenter cohort of LT patients, we retrospectively reviewed those carrying pathogenic TRG variations (n = 38; TERT, n = 23, TERC, n = 9, RTEL1, n = 6) between 2009 and 2018.

Coping strategies, anxiety and depression related to the COVID-19 pandemic in lung transplant candidates and recipients. Results from a monocenter series.

Background: The COVID-19 pandemic has been associated with an increase in anxiety and depression symptoms in people. We investigated the impact of the pandemic on coping strategies and anxiety and depression in lung transplantation (LT) recipients and patients with end-stage chronic lung disease awaiting LT.

Methods: We retrospectively investigated coping strategies by using the Coping Inventory for Stressful Situations questionnaire and anxiety and depression symptoms by the Hospital Anxiety and Depression scale in 115 LT candidates and recipients.

Harmful neutrophil subsets in patients with ischemic stroke: Association with disease severity.

Objective: To better understand the functional state of circulating neutrophils in patients with ischemic stroke (IS) for planning future clinical trials.

Methods: We analyzed by flow cytometry activation state of circulating neutrophils and the distribution of neutrophil peripheral subsets in 41 patients with acute IS less than 6 hours before admission and compared them with 22 age-matched healthy controls.

Results: Our results demonstrated continuous basal hyperactivation of circulating neutrophils during acute IS, characterized by lower l-selectin expression and higher CD11b expression at the cell surface, increased ROS production by neutrophils, and greater circulating levels of neutrophil elastase.
