Anticipating New Treatments for Cystic Fibrosis: A Global Survey of Researchers

[A systemic gene therapy for the treatment of cystic fibrosis]

Le master I2VB se propose de donner les bases conceptuelles et pratiques des différents aspects de l’infectiologie. Il s’appuie sur une coopération exemplaire entre les équipes de recherche en infectiologie et en immunologie de l’Université de Tours, et celles, entre autres, de l’Unité Infectiologie et Santé Publique (ISP) du Centre INRAE de Tours-Nouzilly, concrétisée par une profonde interaction entre chercheurs et enseignants-chercheurs.

Cette formation aborde aussi bien les aspects fondamentaux et appliqués de l’infectiologie et de l’immunologie allant de l’étude moléculaire des interactions entre le pathogène et son hôte, jusqu’à la conception et la mise sur le marché des produits de la vaccinologie, des biothérapies anti-infectieuses et des anticorps immuno-thérapeutiques.

Le master I2VB (niveau M1) donne lieu aux parcours ICM, I&B et AcT (niveau M2).

Advances for pediatricians in 2022: allergy, anesthesiology, cardiology, dermatology, endocrinology, gastroenterology, genetics, global health, infectious diseases, metabolism, neonatology, neurology, oncology, pulmonology

The last year saw intensive efforts to advance knowledge in pediatric medicine. This review highlights important publications that have been issued in the Italian Journal of Pediatrics in 2022. We have chosen papers in the fields of allergy, anesthesiology, cardiology, dermatology, endocrinology, gastroenterology, genetics, global health, infectious diseases, metabolism, neonatology, neurology, oncology, pulmonology. Novel valuable developments in epidemiology, pathophysiology, prevention, diagnosis and treatment that can rapidly change the approach to diseases in childhood have been included and discussed.

Advances in Cystic Fibrosis Research in Qatar: A Commentary

Cystic fibrosis is a genetic disorder caused by a Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene defect. Many across the globe suffer the debilitating symptoms. The aim of this commentary is to briefly cover various aspects related to the disease in the Arab world and then in Qatar.

Dornase alfa in Cystic Fibrosis: indications, comparative studies and effects on lung clearance index

Cystic fibrosis (CF) is the most common inherited disease in Caucasian populations, affecting around 50,000 patients in Europe and 30,000 in United States. A mutation in CF trans-membrane conductance regulator (CFTR) gene changes a protein (a regulated chloride channel), which is expressed in many tissues. Defective CFTR results in reduced chloride secretion and an overage absorption of sodium across the epithelia, leading to thickened secretions in organs such as pancreas and lung. Gradually, there have been considerable improvements in the survival of people with CF, thanks to substantial changes in specialized CF care and the discovery of new CFTR modulators drugs. Nevertheless, lung disease remains the most common cause of death. For these reasons improvement of sputum clearance is a major therapeutic aim in CF. So far, symptomatic mucolytic therapy is mainly based on inhalation of dornase alfa, hypertonic saline or mannitol, in combination with physiotherapy. The major component of mucus in CF is pus including viscous material such as polymerized DNA derived from degraded neutrophils. Dornase alfa cleaves the DNA released from the neutrophils and reduces mucous viscosity, and further prevent airway infections and damage to the lung parenchyma. In this review we will summarize the current knowledge on dornase alfa in the treatment of CF lung disease, especially highlighting the positive effect on lung clearance index, a sensitive measure of ventilation inhomogeneity.
