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.

Pulmonary hypertension associated with lung diseases.

Pulmonary hypertension (PH) associated with chronic lung disease (CLD) is both common and underrecognised. The presence of PH in the setting of lung disease has been consistently shown to be associated with worse outcomes. Recent epidemiological studies have advanced understanding of the heterogeneity of this patient population and shown that defining both the specific type of CLD as well as the severity of PH ( deeper phenotyping) is necessary to inform natural history and prognosis.

Evidence and unresolved questions in pulmonary hypertension: Insights from the 5th French Pulmonary Hypertension Network Meeting.

Pulmonary hypertension (PH) continues to present significant challenges to the medical community, both in terms of diagnosis and treatment. The advent of the updated 2022 European Society of Cardiology (ESC) and European Respiratory Society (ERS) guidelines has introduced pivotal changes that reflect the rapidly advancing understanding of this complex disease. These changes include a revised definition of PH, updates to the classification system, and treatment algorithm.

Background: Objective structured clinical examinations (OSCEs) are extensively used in many medical schools worldwide with the stated objective to assess students' clinical skills acquired during internships. The objective of the present study was to assess the factors associated with success in university summative OSCEs, especially the impact of previous hospital internships in corresponding disciplines and supervision during internships.

Methods: This was a cross-sectional study assessing the results in the summative OSCEs of 4th year medical students during the 2021-2022 academic year in a French medical school.

Pulmonary hypertension associated with diazoxide: the SUR1 paradox.

The ATP-sensitive potassium channels and their regulatory subunits, sulfonylurea receptor 1 (SUR1/Kir6.2) and SUR2/Kir6.1, contribute to the pathophysiology of pulmonary hypertension (PH).

Central role of ubiquitin-specific protease 8 in leptin signaling pathway in pulmonary arterial hypertension.

Background: Leptin receptor (ObR-b) is overexpressed in pulmonary artery smooth muscle cells (PA-SMCs) from patients with pulmonary arterial hypertension (PAH) and is implicated in both mechanisms that contribute to pulmonary vascular remodeling: hyperproliferation and inflammation. Our aim was to investigate the role of ubiquitin-specific peptidase 8 (USP8) in ObR-b overexpression in PAH.

Methods: We performed in situ and in vitro experiments in human lung specimens and isolated PA-SMCs combined with 2 different in vivo models in rodents and we generated a mouse with an inducible USP8 deletion specifically in smooth muscles.

Radiological pulmonary sequelae after COVID-19 and correlation with clinical and functional pulmonary evaluation: results of a prospective cohort.

Objectives: Whether COVID-19 leads to long-term pulmonary sequelae or not remains unknown. The aim of this study was to assess the prevalence of persisting radiological pulmonary fibrotic lesions in patients hospitalized for COVID-19.

Materials And Methods: We conducted a prospective single-center study among patients hospitalized for COVID-19 between March and May 2020.

Clinical Phenotype and Outcomes of Pulmonary Hypertension Associated with Myeloproliferative Neoplasms: A Population-based Study.

Precapillary pulmonary hypertension (PH) is a rare and largely unrecognized complication of myeloproliferative neoplasms (MPNs), including polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (MF). To describe characteristics and outcomes of MPN-associated PH. We report clinical, functional, and hemodynamic characteristics, classification, and outcomes of patients with PV, ET, or primary MF in the French PH registry.

Functional respiratory complaints among COVID-19 survivors: a prospective cohort study.

Background: Dyspnoea is a common persistent symptom after COVID-19. Whether it is associated with functional respiratory disorders remains unclear.

Methods: We assessed the proportion and characteristics of patients with "functional respiratory complaints" (FRCs) (as defined by Nijmegen Questionnaire >22) among 177 post-COVID-19 individuals who benefited from outclinic evaluation in the COMEBAC study (, symptomatic and/or intensive care unit (ICU) survivors at 4 months).

[Physiopathology and treatment of pulmonary arterial hypertension].

Pulmonary arterial hypertension (PAH) is a rare disease affecting mainly the pre-capillary pulmonary vascular bed. However, some forms of the disease have venous/capillary involvement. It is an obstructive remodelling of the pulmonary arterioles coupled with vascular pruning, increasing right ventricular afterload and leading to right heart failure.

ERS International Congress 2021: highlights from the Pulmonary Vascular Diseases Assembly.

This article aims to summarise the latest research presented at the virtual 2021 European Respiratory Society (ERS) International Congress in the field of pulmonary vascular disease. In light of the current guidelines and proceedings, knowledge gaps are addressed and the newest findings of the various forms of pulmonary hypertension as well as key points on pulmonary embolism are discussed. Despite the comprehensive coverage of the guidelines for pulmonary embolism at previous conferences, discussions about controversies in the diagnosis and treatment of this condition in specific cases were debated and are addressed in the first section of this article.

Diagnostic Performance of Pulsed Doppler Ultrasound of the Common Femoral Vein to Detect Elevated Right Atrial Pressure in Pulmonary Hypertension.

Right atrial pressure (RAP) is an important prognostic criterion in pulmonary hypertension (PH). The main goals were to evaluate the following: (i) the accuracy of Doppler assessment of common femoral vein flow waveform to detect elevated RAP and (ii) the diagnostic accuracy of RAP assessed by echocardiography (eRAP). Fifty-seven patients, addressed for right heart catheterization, were included in a retrospective cross-sectional study during a 6-month period.

COVID-19 in Patients with Pulmonary Hypertension: A National Prospective Cohort Study.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is associated with pulmonary endothelial dysfunction. There are limited data available on the outcomes of coronavirus disease (COVID-19) in patients with pulmonary hypertension (PH), a disease characterized by pulmonary endothelial dysfunction. To describe characteristics and outcomes of patients with precapillary PH and COVID-19.

Post-acute COVID-19 syndrome.

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the coronavirus disease 2019 (COVID-19) pandemic that has resulted in millions of deaths and a major strain on health systems worldwide. Medical treatments for COVID-19 (anticoagulants, corticosteroids, anti-inflammatory drugs, oxygenation therapy and ventilation) and vaccination have improved patient outcomes. The majority of patients will recover spontaneously or after acute-phase management, but clinicians are now faced with long-term complications of COVID-19 including a large variety of symptoms, defined as "post-acute COVID-19 syndrome".

Objective structured clinical examinations (OSCEs) for students' training and assessment in the French respiratory medicine departments in 2021: An overview.

Background: Medical professional performances can be assessed by objective structured clinical examinations (OSCEs) where medical trainees go through a series of simulated clinical situations. OSCEs are now the gold standard for the assessment of medical students' competence during their training. In France, the first national OSCEs will take place in May 2024 and respiratory teachers will be involved in this reform and will use OSCEs for students' training and assessment in respiratory medicine.

Endothelial dysfunction and hypercoagulability in severe sickle-cell acute chest syndrome.

Rationale: Acute pulmonary hypertension (PH) may develop during sickle-cell acute chest syndrome (ACS), and is associated with an increased mortality. Its mechanisms remain poorly known. We questioned whether there is endothelial dysfunction and hypercoagulability in severe ACS, with and without acute PH.

External validation of a refined four-stratum risk assessment score from the French pulmonary hypertension registry.

Introduction: Contemporary risk assessment tools categorise patients with pulmonary arterial hypertension (PAH) as low, intermediate or high risk. A minority of patients achieve low risk status with most remaining intermediate risk. Our aim was to validate a four-stratum risk assessment approach categorising patients as low, intermediate-low, intermediate-high or high risk, as proposed by the Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension (COMPERA) investigators.
