Antibody-mediated rejection (AMR) has been recognized as a significant cause of acute and chronic lung allograft dysfunction after lung transplantation. Some treatments, eculizumab, an anti-complement (C)5 component monoclonal antibody (Mab), seem to have a promising effect in the management of some patients with AMR. We present two patients with acute AMR after lung transplantation who received the anti-C5 Mab therapy.

Functional exercise testing (FET) assesses an individual's capacity to adapt to effort and identifies limiting factors, particularly dyspnea. It orients therapeutic choices, predicts the progression of chronic pathologies, and estimates preoperative risks, at times contraindicating surgery. The aim of this article is to provide a summary of the specific indications for functional exercise testing, test protocol selection, test equipment, appropriate personnel, and patient and test safety.

Standard immunosuppressive therapy for lung transplant recipients combines a calcineurin inhibitor, an antimetabolite, and corticosteroids. In an observational, retrospective, monocentric study, we sought to compare the development of chronic lung allograft dysfunction (CLAD) between 37 patients who received this standard therapy (triple-therapy group) and 59 patients who received the mammalian target of rapamycin (mTOR) inhibitor everolimus in addition to the standard therapy (quadruple-therapy group). In the quadruple-therapy group, the time elapsed from transplantation to everolimus introduction (median [25th-75th percentile]) was 12 [7-25] months.

Background: Most lung cancers are diagnosed at an advanced stage and therefore have a poor prognosis. One major challenge is to choose the most adapted sampling technique to obtain a rapid pathological diagnosis so as to start treatment as early as possible. A growing number of techniques have been developed in recent years.

Article Synopsis
  • Forced vital capacity (FVC) and lung transfer of carbon monoxide (TLCO) are both important tests for measuring how bad a lung disease called idiopathic pulmonary fibrosis (IPF) is, but TLCO is better at showing the disease's severity.
  • * In a study of 430 IPF patients, many with "normal" FVC actually had "abnormal" TLCO, meaning FVC alone might not tell the whole story about lung health.
  • * The research found that most patients with a decline in TLCO also had a decline in FVC, but the opposite was not true, suggesting TLCO should be given more attention in monitoring IPF.

Introduction: Chronic obstructive pulmonary disease (COPD) is associated with disabling respiratory symptoms including dyspnea, frequent exacerbations and chronic bronchitis. The currently available pharmacological and non-pharmacological therapies have limited efficacy, necessitating the development of interventional strategies, many of them endoscopic.

State Of The Art: Endoscopic lung volume reduction has markedly increased over recent years, principally as regards the endobronchial valves currently used in routine care.

Article Synopsis
  • The study aimed to develop a prediction model to identify mild COVID-19 patients at risk of worsening, utilizing clinical, biological, and chest CT data.
  • It involved training and validating the model across multiple hospitals, incorporating factors like age, gender, and lymphocyte counts alongside CT scan analysis.
  • Results indicated that combining CT scan quantification and radiomics with clinical parameters significantly improved prediction accuracy for identifying patients likely to develop more severe COVID-19.*

Background: The identification of the first ventilatory threshold (VT1) on an incremental cardiopulmonary exercise test (CPET) is useful to guide exercise reconditioning. However, determination of the VT1 is sometimes difficult in patients with chronic respiratory disease. Our hypothesis was that it would be possible to identify a "clinical threshold" based on patients' perceptions at which they subjectively consider that they can perform endurance training during a rehabilitation programme.

The rheology of sputum is viewed as a powerful emerging biophysical marker for monitoring muco-obstructive pulmonary diseases such as cystic fibrosis (CF) and non-CF bronchiectasis (NCFB). However, there is no unified practice to process sputa from collection to analysis, which can lead to highly variable, and sometimes inconsistent results. The main objective of this study is to bring light into the handling of sputum samples to establish a standardised and robust protocol before rheological measurements.

Purpose: Patients with pulmonary hypertension (PH) have long been advised to avoid exercise in fear of deterioration in right-sided heart function. Since the 2009 European Society of Cardiology guidelines, rehabilitation in expert centers is considered to have a specific role in care of patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). We report routine rehabilitation effects in patients with PH as a component of real-life multimodal treatment.

Introduction: Several studies in COPD have shown a significant and early increase in the risk of cardiovascular mortality attributable to inhaled bronchodilators including long acting β2 agonists (LABAs) and muscarinic antagonists (LAMAs). Cardiac autonomic system impairment may be a potential mechanism involved.

Methods: We performed a phase 4, investigator-initiated, prospective, randomized, blinded, cross-over trial (LAB-Card trial - NCT02872090) to evaluate the effect of two LAMAs and one LABA on the cardiac autonomic system in patients with COPD by using three major assessment approaches: heart rate variability (HRV, a predictor of cardiovascular death), baroreflex sensitivity (BRS) and autonomic function (tilt test).

The management of immunosuppressors in solid organ transplantation requires pharmacological therapeutic monitoring with regular adaptation of the dosage to the residual level. An obvious cause of these fluctuations is drug interactions, particularly for mTOR inhibitors and anti-calcineurin drugs, which are highly metabolized by cytochromes P450. A 72-year-old lung transplanted man, treated by tacrolimus and everolimus in the long term, had his residual immunosuppressor levels unbalanced by the introduction of sotorasib, which is used for metastatic pulmonary adenocarcinoma.

The progression of chronic obstructive pulmonary disease (COPD) is characterized by episodes of acute exacerbation (AECOPD) of symptoms, decline in respiratory function, and reduction in quality-of-life increasing morbi-mortality and often requiring hospitalization. Exacerbations can be triggered by environmental exposures, changes in lifestyle, and/or physiological and psychological factors to greater or lesser extents depending on the individual's COPD phenotype. The prediction and early detection of an exacerbation might allow patients and physicians to better manage the acute phase.

Article Synopsis
  • The research focuses on assessing the rate of avoidable 30-day readmissions for patients hospitalized with community-acquired pneumonia (CAP) and highlights the lack of a clear definition for what constitutes an avoidable readmission.
  • Conducted as a cohort study in two French hospitals, the analysis looked at clinical records from 2014 and involved reviews by board-certified physicians to determine whether readmissions were avoidable based on specific criteria.
  • Out of 1,150 patients hospitalized for CAP, 9.4% experienced unplanned readmissions, and the study found that 13.9% of these were deemed potentially avoidable, indicating room for improvement in hospital care and discharge planning.
