What is the true target population for biologics in real-life COPD or asthma-COPD overlap patients?

Introduction: Biologics provide significant benefits in asthma, reducing exacerbations and symptoms. Some biologics have shown promising results in small subgroups of patients with chronic obstructive pulmonary disease (COPD) and frequent exacerbations. Nevertheless, real-life data on the size of the COPD target population remain scarce.

Evaluation of efficacy and safety of rituximab in patients with progressive interstitial lung disease (ILD) with inflammatory component (EvER-ILD2): A multicentre double-blind placebo-controlled randomized trial.

Introduction: Progressive interstitial lung diseases (ILDs) are rare but severe diseases, with high mortality and morbidity, with no effective pharmacological treatment allowing for long-term remission, and therefore no clear therapeutic recommendations. Several ILDs present inflammatory components (ILDic), which may justify the use of anti-inflammatory and immunosuppressive drugs, as first-step therapy. Except for systemic sclerosis (SSc)-ILD and sarcoidosis, the evidence in favor of this approach is very weak.

Childhood interstitial lung disease survivors in adulthood: a European collaborative study.

Background: Interstitial lung disease (ILD) is rarer in children (chILD) than adults, but with increasing diagnostic awareness, more cases are being discovered. chILD prognosis is often poor, but increasing numbers are now surviving into adulthood.

Aim: To characterize chILD-survivors and identify their impact on adult-ILD centers.

Pulmonary fibrosis in patients with autoimmune pulmonary alveolar proteinosis: a retrospective nationwide cohort study.

Background: Autoimmune pulmonary alveolar proteinosis (aPAP) is a rare disease that may progress towards pulmonary fibrosis. Data about fibrosis prevalence and risk factors are lacking.

Methods: In this retrospective multicentre nationwide cohort, we included patients newly diagnosed with aPAP between 2008 and 2018 in France and Belgium.

Pulmonary Hypertension Associated With Trastuzumab-Emtansine: An Analysis of French PH Registry and WHO Pharmacovigilance Database.

Background: Trastuzumab emtansine has been recently suspected to be associated with the development of pulmonary arterial hypertension (PAH).

Research Question: Is there an association between trastuzumab, trastuzumab emtansine, or trastuzumab deruxtecan and the development of PAH?.

Study Design And Methods: Characteristics of incident PAH cases treated with trastuzumab, trastuzumab emtansine, or trastuzumab deruxtecan were analyzed from the French PH Registry, the VIGIAPATH program, concurrently with a pharmacovigilance disproportionality analysis using the World Health Organization pharmacovigilance database using a broad definition of pulmonary hypertension (PH) and a narrow definition of PAH.

Rare genetic interstitial lung diseases: a pictorial essay.

The main monogenic causes of pulmonary fibrosis in adults are mutations in telomere-related genes. These mutations may be associated with extrapulmonary signs (hepatic, haematological and dermatological) and typically present radiologically as usual interstitial pneumonia or unclassifiable fibrosis. In children, the monogenic causes of pulmonary fibrosis are dominated by mutations in surfactant-related genes.

Diffuse lung diseases ascribed to drugs: a nationwide observational study over 37 years using the French pharmacovigilance database.

Background: Drug-induced interstitial lung disease (DI-ILD) is a heterogeneous subgroup of interstitial lung diseases (ILD). The number of molecules involved is increasing with time. Due to their low incidence, DI-ILDs may be detected only after a drug has been marketed, notably through Adverse Drug Reaction (ADR) reports to pharmacovigilance centres.

Cardiac rhabdomyoma: a rare feature of Birt-Hogg-Dubé syndrome.

Birt-Hogg-Dubé syndrome (BHDS) is a rare autosomal disorder, primarily characterised in adults by cutaneous features, pulmonary cysts that predispose to spontaneous pneumothorax and renal tumours. The syndrome is caused by pathogenic variants in the tumour suppressor gene, which plays a role in the mammalian target of rapamycin (mTOR) signalling pathway. We present the case of a newborn infant diagnosed with BHDS, who died of sudden cardiac death due to complications from cardiac rhabdomyoma.

Identification of FGFR4 as a regulator of myofibroblast differentiation in pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a devastating lung disease with limited therapeutic options. Fibroblast growth factor receptor-4 (FGFR4) is a known receptor for several paracrine fibroblast growth factors (FGFs). FGFR4 is also the main receptor for FGF19, an endocrine FGF that was demonstrated by our group to have antifibrotic properties in the lung.

Sarcoidosis and Emergency Hospitalization.

Background: Sarcoidosis is an idiopathic systemic granulomatosis whose evolution is self-limiting in most cases. However, it can progress to organ damage that menaces the vital or functional prognosis of patients. Sarcoidosis itself, but also its comorbidities, can pose a threat to the patient, require rapid initiation of treatment, and justify emergency hospitalization.

Cystic lung in sarcoidosis: Clinico-radiologic characteristic and evolution.

Background And Objective: Sarcoidosis can manifest with atypical findings on chest computed tomography (CT). Cysts are a rare manifestation of lung sarcoidosis. The aim of the study was to describe a series of patients with cystic sarcoidosis and their clinical-radiological characteristics and progression.

Outcomes of lung transplantation for pleuroparenchymal fibroelastosis: A French multicentric retrospective study.

Background: Pleuroparenchymal fibroelastosis (PPFE) has no currently available specific treatment. Benefits of lung transplantation (LT) for PPFE are poorly documented.

Methods: We conducted a nation-wide multicentric retrospective study in patients who underwent lung or heart-lung transplantation for chronic end-stage lung disease secondary to PPFE between 2012 and 2022 in France.
