Factors reducing omalizumab response in severe asthma
2018
Background: Despite adding Omalizumab to conventional therapy, several severe asthmatics still show poor disease control. We investigated the factors that may affect a reduced Omalizumab response in a large population of severe asthmatics. Methods: 340 patients were retrospectively evaluated. FEV1%, FVC%, Asthma Control Test (ACT), fractional exhaled nitric oxide (FENO), possible step-downs/step-ups of concomitant therapies, exacerbations, disease control levels, ICS doses and SABA use, observed at the end of treatment, were considered as a response to Omalizumab. Results: Age was an independent risk factor for a reduced response concerning FEV1%, FVC%, ACT and for a lower asthma control. O…
Bulbar impairment score predicts noninvasive volume-cycled ventilation failure during an acute lower respiratory tract infection in ALS.
2015
Amyotrophic lateral sclerosis (ALS) patients can suffer episodes of lower respiratory tract infections (LRTI) leading to an acute respiratory failure (ARF) requiring noninvasive ventilation (NIV).To determine whether clinical or functional parameters can predict noninvasive management failure during LRTI causing ARF in ALS.A prospective study involving all ALS patients with ARF requiring NIV in a Respiratory Care Unit. NIV was provided with volume-cycled ventilators.63 ALS patients were included (APACHE II: 14.93±3.56, Norris bulbar subscore (NBS): 18.78±9.68, ALSFRS-R: 19.90±6.98, %FVC: 40.01±18.07%, MIC: 1.62±0.74L, PCF 2.51±1.15L/s, PImax -34.90±19.44cmH2O, PEmax 51.20±28.84cmH2O).

Global Lung Function Initiative 2012 reference values for spirometry in South Italian children
2017
Rationale Despite the widespread use of the Global Lung Function Initiative (GLI) 2012 reference values, there is still the need of testing their applicability in local areas. Objectives The aims of this study are to evaluate applicability of GLI reference equations in a large population-based sample of normal schoolchildren from Sicily, and to compare GLI and previous prediction equations in terms of spirometry test interpretation. Methods GLI equations were evaluated in 1243 normal schoolchildren, 49% males, aged 7â16 years, height 116â187 cm. Normality assumptions for the GLI z-scores (FEV1, FVC, FEV1/FVC) were tested, and bootstrap confidence intervals for the mean (0 expected) and …

Pulmonary function and complications after laparoscopic cholecystectomy
1998
Objective: To investigate the impairment of pulmonary function and complications after laparoscopic compared with open cholecystectomy through an upper midline incision.Design: Prospective randomised trial.Setting: Teaching hospital, Spain.Subjects: 40 patients, 20 in each group.Interventions: Clinical examination, spirometry, arterial blood gas analysis, and chest radiographs before and after operation.Results: 48 hours postoperatively FVC and FEV had decreased to 56.7% and 53%, respectively, in the patients who had had open cholecystectomy, compared with 85.3% and 84.8% in the laparoscopic group (p < 0.0001). The mean (SD) postoperative percentage reductions in both Pa02 (86.1 (11.1) comp…
Associations of black carbon with lung function and airway inflammation in schoolchildren
2019
Background: Few studies have investigated the 24-hour respiratory health effects of personal black carbon (BC) and ultrafine particles (UFP) exposure in schoolchildren. The objective of this study was to investigate these associations with the lung function in children 10-years old with and without persistent respiratory symptoms. Methods: We conducted a cross-sectional study in 305 children (147 and 158 with and without persistent respiratory symptoms, respectively) from three European birth-cohorts: PARIS (France) and INMA Sabadell and Valencia (Spain). Personal 24-hour measurements of exposure concentrations to BC and UFP were performed by portable devices, before lung function testing. …
Isotonic Saline Nebulization and Lung Function in Children With Mild Respiratory Ailments
2020
Nebulization with saline solution, although commonly used to alleviate respiratory symptoms, particularly in children, is often questioned concerning its effectiveness. In this study, we investigated the effects of isotonic saline nebulization on lung function in 40 children (mean age of 14±1 years) suffering from different types of airway disorders. Measurements were carried out directly before and up to 15 min after nebulization, for six days in a row, always on the same day time in the morning. The children were divided into two study groups according to the baseline ratio of forced expired volume in one second/forced vital capacity (FEV1/FVC), below and above 80 %. We found significant …
The characteristics of different diagnostic tests in adult mild asthmatic patients: Comparison with patients with asthma-like symptoms by gastro-oeso…
2007
SummaryBackgroundDiagnosing asthma cannot be always easy. It is important to consider the validity of the diagnostic tests, and/or how much more commonly they are positive in patients with asthma compared to healthy subjects and, particularly, to patients with asthma-like symptoms.ObjectiveTo evaluate the validity of diagnostic tests for asthma, in terms of sensitivity, specificity, positive and negative predictive values, in patients with bronchial asthma compared to patients affected by gastro-oesophageal reflux disease (GERD) with asthma-like symptoms, and healthy control subjects without asthma and gastro-oesophageal reflux (GER).DesignSingle-center, cross-sectional, observational study…
GOLD and the fixed ratio
2012
We thank Dr Vestbo for his interest in our manuscript “Diagnosis of airway obstruction in the elderly: contribution of the SARA study” and for the opportunity to clarify some points. As mentioned in the title and aims, the intent of the paper is to offer a contribution to the open issue of identification of airway obstruction in elderly people.1 We agree with Dr Vestbo about the utility of distinguishing between the clinical and functional aspects of chronic obstructive pulmonary disease (COPD). We stress that, until the term COPD is used, diagnosis needs clinical evidence of a chronic pulmonary disease and functional evidence of airway obstruction. Given that symptoms compatible with COPD …
Noninvasive respiratory muscle aids during PEG placement in ALS patients with severe ventilatory impairment.
2010
Abstract Although no clear recommendations are given about when percutaneous endoscopic gastrostomy (PEG) should be placed in amyotrophic lateral sclerosis (ALS) patients, some experts underline the risk of respiratory complications when patients had severe ventilatory muscle impairment (SVMI). Aim To evaluate the efficacy of noninvasive ventilation (NIV) and mechanically assisted cough (MAC) to avoid respiratory complications related to PEG placement in ALS patients with SVMI. Material and methods Prospective study including ALS patients who had chosen to have PEG placement timed by swallowing dysfunction with the aid of NIV and MAC if needed. PEG was carried out under volume-cycled NIV th…
