Background: The pulmonary involvement in patients with microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) is well known at disease onset but data during follow-up (after the induction regimen and when the first relapse occurs) are limited. Our goal was to analyze chest high-resolution computed tomography (HRCT) findings of (ANCA)-associated vasculitis patients.

Method: All consecutive unselected AAV patients over eighteen with positive ANCA status and with HRCT chest performed at the diagnosis were retrospectively enrolled between 2004 and 2019 at the Toulouse University Hospital (France).

Background And Objective: Dynamic hyperinflation (DH) is a major marker of exertional dyspnoea in severe emphysema. We hypothesized that bronchoscopic lung volume reduction (BLVR) using endobronchial valves (EBVs) decreases DH.

Methods: In this prospective bi-centre study from both Toulouse and Limoges Hospitals, we assessed DH during an incremental cycle ergometry before and 3 months after EBVs treatment.

Objective: To evaluate extent of interstitial lung disease (ILD) and oesophageal involvement using high-resolution computed tomography (HRCT) in early diffuse SSc patients after autologous haematopoietic stem cell transplantation (aHSCT).

Methods: Overall chest HRCT, lung function and skin score changes were evaluated in 33 consecutive diffuse SSc patients before and after aHSCT during yearly routine follow-up visits between January 2000 and September 2016. Two independent radiologists blindly assessed the ILD extent using semi-quantitative Goh and Wells method, the widest oesophageal diameter (WOD) and the oesophageal volume (OV) on HRCT.

Background: The effects of SARS-CoV-2 (COVID-19) on the myocardium and their role in the clinical course of infected patients are still unknown. The severity of SARS-CoV-2 is driven by hyperinflammation, and the effects of SARS-CoV-2 on the myocardium may be significant. This study proposes to use bedside observations and biomarkers to characterize the association of COVID-19 with myocardial injury.

Background: Since successful development of endobronchial valves (EBV) as treatment for severe emphysema, its main complication, pneumothorax, remains an important concern.

Objective: We hypothesized that a two-step EBV implantation, during two distinct iterative procedures could lead to a more progressive target lobe volume reduction (TLVR) and thus ipsilateral lobe re-expansion, resulting in a significant decrease in the pneumothorax rate.

Methods: This retrospective bi-center study carried out by Limoges and Toulouse University Hospitals included patients following the inclusion criteria established by the BLVR expert panel.

Immunotherapy has become a standard of care in oncology, following the recent approvals of cytotoxic T-lymphocyte-associated protein-4 and programmed cell death-1 inhibitors in lung cancer, melanoma, renal cell carcinoma, Hodgkin's lymphoma, bladder, head and neck cancers. Besides their efficacy, these agents also generate specific immune-related adverse events. Due to the increasing prescription of immune-checkpoint inhibitors, the incidence of immune toxicity will continue to rise.

Article Synopsis
  • Immunotherapy, particularly immune-checkpoint inhibitors (ICI), is now a standard treatment for many cancers but can lead to adverse events like interstitial lung disease (ILD).
  • A study identified that 3.5% of cancer patients receiving ICI developed ILD, predominantly affecting males and those with smoking history, with a median onset time of 2.3 months.
  • Common radiological findings included ground-glass opacities and consolidations, and after 6 months, the overall survival rate for affected patients was 58.1%.
