Article Synopsis
  • * This study analyzed cases of C bantiana infections in France and its territories, involving patients who were diagnosed through a comprehensive surveillance program, focusing on survival rates and the presence of central nervous system (CNS) involvement.
  • * Out of 23 patients identified from 2002 to 2022, 65% had CNS involvement, with a notable increase in cases reported in 2022, indicating a possible correlation with environmental factors like rising temperatures.

BACKGROUND Lung transplantation (LTx) is a life-extending therapy for specific patients with terminal lung diseases. This study aimed to evaluate the associations and causes of 1-year mortality after lung transplantation at Strasbourg University Hospital, France, between 2012 and 2021. MATERIAL AND METHODS We carried out a retrospective analysis on 425 patients who underwent LTx at Strasbourg University Hospital between January 1, 2012, and December 31, 2021.

Article Synopsis
  • The study examined the impact of COVID-19 lockdowns on lung transplant (LT) patients in France, focusing on three key periods: the first lockdown, the end of the first lockdown, and the second lockdown.
  • It included 283 LT patients and 57 with rare lung diseases, finding only eight COVID-19 cases among LT patients across all periods, with favorable outcomes and no cases in the rare lung disease group.
  • Lifestyle changes were noted, with increased outdoor activities and professional engagements after the first lockdown, while adherence to protective measures against COVID-19 remained high among both patient groups.

Background: Several rare surfactant-related gene (SRG) variants associated with interstitial lung disease are suspected to be associated with lung cancer, but data are missing. We aimed to study the epidemiology and phenotype of lung cancer in an international cohort of SRG variant carriers.

Methods: We conducted a cross-sectional study of all adults with SRG variants in the OrphaLung network and compared lung cancer risk with telomere-related gene (TRG) variant carriers.

Background: Interstitial lung disease associated with genetic disorders of the surfactant system is a rare entity in adults that can lead to lung transplantation. Our objective was to describe the outcome of these patients after lung transplantation.

Methods: We conducted a retrospective, multicentre study, on adults who underwent lung transplantation for such disease in the French lung transplant centres network, from 1997 to 2018.

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.

Background: Bronchiolitis obliterans syndrome (BOS) is the main limitation to long-term survival following lung transplantation. Several studies generated promising results regarding the efficacy of extracorporeal photopheresis (ECP) in BOS management. We aimed to compare FEV1 evolution in ECP-treated versus non-ECP treated patients among BOS recipients.

Rational: Pending the authorization of new anti-CMV drugs with fewer adverse effects, exploring the possibilities offered by CMV immunoglobulins (CMVIG) seems necessary. In France, access to CMVIG requires official authorization by the national Health authority and is restricted to second line rescue therapy for CMV infection/disease. The aim of this multicenter retrospective study is to describe the indications and clinical situations that justified its use in France.

Background: Recent studies report very low adherence of practitioners to ATS/IDSA recommendations for the treatment of nontuberculous mycobacteria pulmonary disease (NTM-PD), as well as a great variability of practices. Type of management could impact prognosis.

Methods: To evaluate management and prognosis of patients with NTM-PD cases with respect to ATS recommendations, we conducted a multicenter retrospective cohort study (18 sentinel sites distributed throughout France), over a period of six years.

Article Synopsis
  • The study investigates the effectiveness and safety of cyclophosphamide for treating patients with acute exacerbation of idiopathic pulmonary fibrosis (IPF) when used alongside high-dose methylprednisolone.
  • Conducted as a double-blind, placebo-controlled trial across 35 departments in France, 120 patients were randomly assigned to receive either cyclophosphamide or a placebo, with all participants monitored for 3-month all-cause mortality.
  • Results showed that 3-month mortality was 45% in the cyclophosphamide group compared to 31% in the placebo group, indicating no significant advantage for cyclophosphamide (p=0.10), and the trial is registered as NCT024605

Background: Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma in the posttransplant setting. Treatment is based on chemotherapy; surgery is still debated and should be performed in very select cases.

Methods: We observed 2 patients out of 300 who underwent lung transplantation in the Nouvel Hopital Civil between 2013 and 2019 with primary hepatic lymphoma.

The clinical and social impacts of the COVID-19 epidemic on lung transplant (LTx) recipients remain poorly known. We aimed to evaluate its social, clinical, and behavioral consequences on the LTx patients followed in Strasbourg university hospital. A questionnaire was used to collect details concerning patients' lifestyles, their protection methods used to avoid COVID-19 contamination, and clinical infection-related information for March 2020.

Background: Lung transplantation (LT) is an identified risk factor for Pneumocystis pneumonia (PCP). However, PCP management and outcomes remain poorly described in LT recipients and PCP incidence is rarely documented in this population.

Methods: PCP episodes that occurred in 9 French LT centers between January 2010 and October 2017 were included in this analysis.

Objective: To study patient survival and glycemic control before and after lung transplantation (LTx) according to the diabetes status in patients submitted to an organized management of diabetes mellitus (DM) at the Strasbourg University Hospital, France.

Material And Methods: Two hundred and sixty-seven LTx recipients were included retrospectively and analyzed according to diabetes status: pretransplant diabetes, new-onset diabetes mellitus after transplant (NODAT) or no diabetes. Organized DM management was coordinated by a diabetologist trained in DM management before and after transplantation and included pretransplant screening, a close monitoring of glycemia after transplant and optimized treatment before and after LTx.

BACKGROUND Although central airway stenosis (CAS) is a common complication after lung transplantation, its consequences have been poorly evaluated. The objective of our study was to evaluate the impact of CAS on lung function after lung transplantation. MATERIAL AND METHODS All lung transplant recipients from June 2009 to August 2014 in a single center (Strasbourg, France) were retrospectively reviewed.

Cladophialophora bantiana brain abscesses are rare, but are frequently and quickly lethal in transplanted patients. We report the case of a 63-year-old man who had undergone lung transplantation for chronic obstructive pulmonary disease and presented with headaches and a neurological deficit. Magnetic resonance imaging revealed multiple brain abscesses.

Background: After lung transplantation (LT), early prediction of grade 3 pulmonary graft dysfunction (PGD) remains a research gap for clinicians. We hypothesized that it could be improved using extravascular lung water (EVLWi) and plasma biomarkers of acute lung injury.

Methods: After institutional review board approval and informed consent, consecutive LT recipients were included.

Objectives: After lung transplant, between 9 and 13% of bronchial anastomoses develop complications severe enough to warrant therapeutic intervention. These complications include stenosis, dehiscence, granulation tissue, bronchomalacia and fistula. Most of these have already been included in a classification or another, but none of these have been universally accepted.
