Omalizumab for the treatment of chronic spontaneous urticaria in clinical practice

2016

Chronic spontaneous urticaria (CSU) is a skin disease that predominantly affects adults, especially women aged 20 to 40 years, and is characterized by the recurrent appearance of localized or widespread wheals, angioedema or both, without apparent external trigger. 1 , 2 Severe CSU has a detrimental effect on the quality of life and is a frequent cause of absenteeism from school and work. [3] The pathogenesis of CSU is not well understood, and it appears to have an autoimmune cause in approximately one-third of patients. [4] Guidelines for the management of CSU recommend the use of second-generation antihistamines, with the addition of leukotriene receptor antagonists, cyclosporine, or omal…

Advances in asthma pathophysiology: stepping forward from the Maurizio Vignola experience

2015

Maurizio Vignola was a superb and innovative researcher, who wrote seminal papers on the biology of airway epithelium in asthma. Inflammation and remodelling were the main topics of his research, mostly conducted in biopsy specimens from patients with asthma of variable severity, encompassing the entire spectrum of the disease from mild to severe asthma. His observations contributed to define the biology of asthma as we know it today, and opened the way to the personalised treatment of asthma. His group has successfully continued to investigate the biology and clinical aspects of bronchial asthma, with major interest in the clinical use of biomarkers to monitor disease activity, and in the …

The Association Between Bone Mineral Density and Airflow Limitation in a Cohort of Fit Elderly Women

2016

Purpose: As studies examining the association between bone mineral density (BMD) and airflow limitation (AL) have produced conflicting results, the current one set out to analyze if and to what degree there are any correlations between these variables in a population of fit elderly women. Methods: One hundred and twenty-one non-smoking, fit and healthy women (age ≥ 65 years) underwent anthropometric assessment, laboratory testing (serum 25-hydroxy vitamin D, parathormone, and cytokine levels), pulmonary function testing (PFT), and dual-energy X-ray absorptiometry to evaluate BMD values of the lumbar and femoral regions. Results: A significant positive association was found between FEV1/FVC …

Lung Function Monitoring; A Randomized Agreement Study

2016

Objective: To determine the agreement between devices and repeatability within devices of the forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF) and forced expiratory flow at 50% of FVC (FEF50) values measured using the four spirometers included in the study. Methods: 50 (24 women) participants (20-64 years of age) completed maximum forced expiratory flow manoeuvres and measurements were performed using the following devices: MasterScreen, SensorMedics, Oxycon Pro and SpiroUSB. The order of the instruments tested was randomized and blinded for both the participants and the technicians. Re-testing was conducted on a following day within 72 hours …

Is an activity volume threshold really realistic for lung cancer resection?

2018

IF 1.804 (2017); International audience; Background:We analyzed volume as a continuous variable to estimate threshold, which is a methodology rarely seen in the literature. The objective of this work was to assess hospital volume for lung cancer (LC) surgery and to establish the associated threshold for acceptable in-hospital mortality (IHM). Data was obtained from the French national medico-administrative database.Methods:From January 2005 to December 2016, data from 108,571 patients operated for LC in France were collected from the national administrative database. To estimate the volume threshold, hierarchical logistic regression models were developed.Results:The crude IHM rate was 5.2% …

Serological biomarkers for the diagnosis of Mycobacterium abscessus infections in cystic fibrosis patients

2021

International audience; Background: Culture conditions sometimes make it difficult to detect non-tuberculous mycobacteria (NTM), particularly Mycobacterium abscessus, an emerging cystic fibrosis (CF) pathogen. The diagnosis of NTM positive cases not detected by classical culture methods might benefit from the development of a serological assay.Methods: As part of a diagnostic accuracy study, a total of 173 sera CF-patients, including 33 patients with M. abscessus positive cultures, and 31 non-CF healthy controls (HC) were evaluated. Four M. abscessus antigens were used separately, comprising two surface extracts (Interphase (INP) and a TLR2 positive extract (TLR2eF)) and two recombinant pro…

Should we use gait speed in COPD, FEV 1 in frailty and dyspnoea in both?

2016

Frailty is a progressive physiological decline in multiple organ systems marked by loss of function, loss of physiological reserve and increased vulnerability to disease [1]. Biological (inflammation and loss of hormones), clinical ( e.g. sarcopenia and osteoporosis) and social factors are involved in frailty onset, evolution and prognosis [2, 3]. Links between frailty, dyspnoea and chronic respiratory diseases represent a novel and practical approach

One-year follow up of asthmatic patients newly initiated on treatment with medium- or high-dose inhaled corticosteroid-long-acting β2-agonist in UK p…

2020

Abstract Introduction Global Initiative for Asthma (GINA) recommends medium- or high-dose inhaled corticosteroid-long-acting β2-agonist (ICS-LABA) as preferred treatments for patients with moderate-to-severe asthma. Limited data is available on how step 4/5 patients respond to ICS-LABA and how they step up/down in clinical practice. Methods This retrospective cohort study assessed the characteristics, control status, treatment pathways, and healthcare resource utilization in patients with asthma during one year after initiating medium- or high-dose ICS-LABA. Data from the United Kingdom Clinical Practice Research Datalink were analysed between January 01, 2006 and February 28, 2016. Results…
