Cumulative Incidence and Risk Factors for Severe Coronavirus Disease 2019 in French People With Cystic Fibrosis.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections are closely monitored in people with cystic fibrosis (pwCF), especially severe cases. Previous studies used hospitalization rates as proxy for severity.

Methods: We evaluated data from coronavirus disease 2019 (COVID-19) cases diagnosed in French pwCF over the first pandemic year.

Clinical practice versus guidelines for the screening of cystic fibrosis-related diabetes: A French survey from the 47 centers.

This study aimed to analyze clinical practices concerning cystic fibrosis-related diabetes (CFRD) screening in France. A web-based questionnaire was distributed between December 1, 2020 and January 31, 2021 among 47 cystic fibrosis centers including pediatric, adult, and mixed units. In accordance with guidelines, 92.

Cystic Fibrosis and Sleep Circadian Rhythms.

Cystic fibrosis (CF) is due to a mutation in the cystic fibrosis transmembrane conductance regulator gene (CFTR), which leads to unusual water and chloride secretion across epithelial surfaces. The lungs are responsible for most morbidity, though other organs are frequently affected. Sleep abnormalities have long been recognized in CF.

Prognostic value of copeptin and mid-regional proadrenomedullin in COVID-19-hospitalized patients.

Background: Biomarkers are used for diagnosis, risk stratification and medical decisions. Copeptin and mid-regional proadrenomedullin (MR-proADM) are markers of stress and endothelial function, respectively, which have been studied in pneumonia, sepsis and septic shock. This study aimed to assess whether copeptin and MR-proADM could predict coronavirus disease 2019 (COVID-19) in-hospital outcomes, that is multi-system complications, length of stay and mortality.

Sustained effectiveness of elexacaftor-tezacaftor-ivacaftor in lung transplant candidates with cystic fibrosis.

Background: Elexacaftor-tezacaftor-ivacaftor induces rapid clinical improvement in patients with cystic fibrosis (CF) and advanced pulmonary disease, often leading to suspend the indication for lung transplantation. Yet no long-term data is available in lung transplant candidates.

Methods: Lung transplant candidates (defined as being waitlisted for lung transplantation or considered for listing within 3 months) who have initiated elexacaftor-tezacaftor-ivacaftor were identified in the French cohort of patients with CF and advanced pulmonary disease.

Bronchiectasis and inhaled tobramycin: A literature review.

Background: Inhaled antibiotics have been incorporated into contemporary European and British guidelines for bronchiectasis, yet no inhaled antibiotics have been approved in the United States or Europe for the treatment of bronchiectasis not related to cystic fibrosis. Pseudomonas aeruginosa infection is common in patients with bronchiectasis, contributing to a cycle of progressive inflammation, exacerbations, and airway remodelling.

Objective: The aim of the current study was to identify and evaluate published studies of inhaled tobramycin solution or powder in patients with bronchiectasis and P.

Factors for severe outcomes following SARS-CoV-2 infection in people with cystic fibrosis in Europe.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in people with cystic fibrosis (pwCF) can lead to severe outcomes.

Methods: In this observational study, the European Cystic Fibrosis Society Patient Registry collected data on pwCF and SARS-CoV-2 infection to estimate incidence, describe clinical presentation and investigate factors associated with severe outcomes using multivariable analysis.

Results: Up to December 31, 2020, 26 countries reported information on 828 pwCF and SARS-CoV-2 infection.

Clinical course and risk factors for severe COVID-19 among Italian patients with cystic fibrosis: a study within the Italian Cystic Fibrosis Society.

Purpose: To describe the clinical course of COVID-19 in patients with cystic fibrosis (CF) and to identify risk factors for severe COVID-19.

Methods: We conducted a prospective study within the Italian CF Society. CF centers collected baseline and follow-up data of patients with virologically confirmed SARS-CoV-2 infection between March 2020 and June 2021.

Severe asthma: One disease and multiple definitions.

Introduction: There is, so far, no universal definition of severe asthma. This definition usually relies on: number of exacerbations, inhaled therapy, need for oral corticosteroids, and respiratory function. The use of such parameters varies in the different definitions used.

Manifesto on the Value of Adult Immunization: "We Know, We Intend, We Advocate".

Immunization through vaccination is a milestone achievement that has made a tremendous contribution to public health. Historically, immunization programs aimed firstly to protect children, who were disproportionally affected by infectious diseases. However, vaccine-preventable diseases can have significant impacts on adult mortality, health, and quality of life.

Employment Status and Work Ability in Adults with Cystic Fibrosis.

Improvements in the survival and clinical outcomes of cystic fibrosis (CF) patients raised questions about their workforce participation and capacity to work. One hundred and ninety-six outpatients, attending the Adult CF Center of an Italian University Hospital, were enrolled between May 2020 and March 2021. The patients' personal and clinical characteristics, employment status, and profession were assessed.

The Isoform GC1f of the Vitamin D Binding Protein Is Associated with Bronchiectasis Severity.

Vitamin D modulates immune responses and its deficiency has been observed in more than 60% of bronchiectasis patients. Vitamin D binding protein (DBP) is coded by the GC gene, is involved in the transport of vitamin D, and includes a number of isoforms based on single nucleotide polymorphisms (SNPs) in the coding region at rs7041 and rs4855. We evaluated the possible clinical impact of DBP polymorphisms and isoforms in an observational, cross-sectional study conducted in 116 bronchiectasis patients, who were genetically characterized for rs4588 and rs7041 SNPs.

A new call for influenza and pneumococcal vaccinations during COVID-19 pandemic in Italy: A SIP/IRS (Italian Respiratory Society) and SITA (Italian Society of Antiinfective therapy) statement.

Influenza and pneumococcal disease represent a well-known burden on healthcare systems worldwide, as well as they still have an attributed morbidity and mortality, especially in elderly individuals and vulnerable populations. In the context of the ongoing pandemic of COVID-19, a series of considerations in favor of extensive influenza and pneumococcal vaccination campaign are emerging, including a possible reduction of hospital extra burden and saving of sanitary resources. In addition, recent studies have suggested that prior vaccinations towards non SARS-CoV-2 pathogens might confer some protection against COVID-19.

NLRC4 GOF Mutations, a Challenging Diagnosis from Neonatal Age to Adulthood.

The NLRC4 inflammasome is part of the human immune innate system. Its activation leads to the cleavage of pro-inflammatory cytokines IL-1β and IL-18, promoting inflammation. gain-of-function (GOF) mutations have been associated with early-onset recurrent fever, recurrent macrophagic activation syndrome and enterocolitis.

Age-dependent impact of the major common genetic risk factor for COVID-19 on severity and mortality.

BackgroundThere is considerable variability in COVID-19 outcomes among younger adults, and some of this variation may be due to genetic predisposition.MethodsWe combined individual level data from 13,888 COVID-19 patients (n = 7185 hospitalized) from 17 cohorts in 9 countries to assess the association of the major common COVID-19 genetic risk factor (chromosome 3 locus tagged by rs10490770) with mortality, COVID-19-related complications, and laboratory values. We next performed metaanalyses using FinnGen and the Columbia University COVID-19 Biobank.

Immune Checkpoints Expression in Chronic Lung Allograft Rejection.

Chronic lung allograft dysfunction (CLAD) is the main cause of poor survival and low quality of life of lung transplanted patients. Several studies have addressed the role of dendritic cells, macrophages, T cells, donor specific as well as anti-HLA antibodies, and interleukins in CLAD, but the expression and function of immune checkpoint molecules has not yet been analyzed, especially in the two CLAD subtypes: BOS (bronchiolitis obliterans syndrome) and RAS (restrictive allograft syndrome). To shed light on this topic, we conducted an observational study on eight consecutive grafts explanted from patients who received lung re-transplantation for CLAD.

The impact of cystic fibrosis on the working life of patients: A systematic review.

Advances in the treatment and management of cystic fibrosis (CF) have led to a substantial increase in patient life expectancy, thus facilitating healthier lives and labour force participation. This review aimed to address the impact of CF on the occupational functioning of patients. A significant proportion of patients were reported to retain a job on a full- or part-time schedule.

Portable High-Flow Nasal Oxygen during Walking in Patients with Severe Chronic Obstructive Pulmonary Disease: A Randomized Controlled Trial.

Background: High-flow nasal oxygen (HFNO) improves exercise capacity, oxygen saturation, and symptoms in patients with chronic obstructive pulmonary disease (COPD). Due to the need of electricity supply, HFNO has not been applied during free ambulation.

Objective: We evaluated whether HFNO delivered during walking by a battery-supplied portable device was more effective than usual portable oxygen in improving exercise capacity in patients with COPD and severe exercise limitation.

Laryngotracheal aspiration test reduce the false negative rate in patients with suspected SARS-COV-2 pneumonia despite a negative nasopharyngeal swab.

Background: In the emergency department (ED) definitive diagnosis of SARS-COV-2 pneumonia is challenging as nasopharyngeal swab (NPS) can give false negative results. Strategies to reduce false negative rate of NPS have limitations. Serial NPSs (24-48 h from one another) are time-consuming, sputum can not be collected in the majority of patients, and bronchoalveolar lavage (BAL), the most sensitive test, requires specific expertise.

Pseudomonas aeruginosa infection, but not mono or dual-combination CFTR modulator therapy affects circulating regulatory T cells in an adult population with cystic fibrosis.

Background: Chronic infection and an exaggerated inflammatory response are key drivers of the pathogenesis of cystic fibrosis (CF), especially CF lung disease. An imbalance of pro- and anti-inflammatory mediators, including dysregulated Th2/Th17 cells and impairment of regulatory T cells (Tregs), maintain CF inflammation. CF transmembrane conductance regulator (CFTR) modulator therapy might influence these immune cell abnormalities.
