Age does not affect the efficacy of anti-IL-5/IL-5R in severe asthmatics
2019
Background: Healthcare decisions made on the basis of insufficient evidence may potentially have ineffective or even harmful consequences. The proportion of older ages (over 65 years) in randomized controlled trials (RCTs) for severe asthma is not enough to establish whether anti-IL-5/IL-5R therapies are equally effective in the elderly as in younger subjects. Methods: In order to assess the relationship between age and the efficacy of anti-IL-5 monoclonal antibodies (mABs) with respect to the risk of exacerbations and changes in FEV1, a meta-regression analysis via random-effect method was carried out by plotting the effect estimates (outcome variables) resulting from the pairwise meta-ana…
Defining moderate asthma exacerbations in clinical trials based on ATS/ERS joint statement
2015
Background Exacerbations are a key outcome in clinical research, providing patient-relevant information about symptomatic control, health state and disease progression. Generally considered as an episode of (sub)acute deterioration of respiratory symptoms, a precise, clinically useful definition is needed for use in clinical trials. Aim and methods Focussing on moderate exacerbations, this opinion piece reviews landmark trials and current guidelines to provide a practical definition of a moderate exacerbation. Specifically, we adapt the ATS/ERS consensus statement of terminology Reddel et al. (2009) [1] which provides a conceptual (or 'theoretical') definition for moderate exacerbations, to…
Eligibility of real-life patients with copd for inclusion in rcts: A commentary
2017
Randomized clinical trials (RCTs) are performed to provide evidence to support treatment decisions. Based on the nature of those studies and the need to avoid confounding factors, it has been argued that the population selected in RCTs only partially represents the real-life population. This assumption casts doubts on the applicability of the results provided by RCTs in the management of individuals with an established diagnosis of COPD, and advocates the need for complementary studies with a pragmatic design. Herein, we comment on the recent article published by Halpin and colleagues on the Journal [Halpin et al, Respir Res 17:120, 2016], in which higher rates of inclusions in RCTs for COP…

The effect of tiotropium/olodaterol versus fluticasone propionate/salmeterol on left ventricular filling and lung hyperinflation in patients with COPD
2020
This exploratory, randomised, double-blind, double-dummy, multicentre, cross-over study explored the effect of 6 weeks of treatment with tiotropium/olodaterol (T/O) versus fluticasone propionate/salmeterol (F/S) on left ventricular filling in patients with chronic obstructive pulmonary disease with functional residual capacity (FRC) >120% predicted and postbronchodilator improvement of FRC ≥7.5%. Overall, 76 patients were randomised across nine sites. Treatment with T/O or F/S increased left ventricular end-diastolic volume index from baseline (adjusted mean change: T/O: 2.317 mL/m2, F/S: 2.855 mL/m2), with no statistically significant difference between treatments. However, T/O resulted…
Withdrawal of inhaled corticosteroids in COPD: A meta-analysis
2017
Background Conflicting findings exist on the benefit of withdrawal of inhaled corticosteroid (ICS) in chronic obstructive pulmonary disease (COPD). We performed a quantitative synthesis in order to assess real impact of ICS discontinuation in COPD patients. Methods We carried out a meta-analysis via random-effects model on the available clinical evidence to evaluate the effect of ICS discontinuation in COPD. Randomized clinical trials and observational real-life studies investigating the effects of ICS withdrawal on the risk of COPD exacerbation, lung function (forced expiratory volume in 1 s [FEV1]) and quality of life (St. George's Respiratory Questionnaire [SGRQ]) were identified by sear…
Unmet needs and challenges in gastric cancer: The way forward
2014
AbstractAlthough the incidence of gastric cancer has fallen steadily in developed countries over the past 50years, outcomes in Western countries remain poor, primarily due to the advanced stage of the disease at presentation. While earlier diagnosis would help to improve outcomes for patients with gastric cancer, better understanding of the biology of the disease is also needed, along with advances in therapy. Indeed, progress in the treatment of gastric cancer has been limited, mainly because of its genetic complexity and heterogeneity. As a result, there is an urgent need to apply precision medicine to the management of the disease in order to ensure that individuals receive the most appr…
Sublingual immunotherapy: administration, dosages, use.
2009
Allergen extracts for sublingual immunotherapy (SLIT) are currently marketed by several manufacturers, with administration schedules and amount of allergen(s) quite variable in the different products, although almost all are standardized biologically or immunologically. The allergen extracts for SLIT are available in two main pharmaceutical forms: solution to be delivered by drop-counters, pre-dosed actuators (mini-pumps) or disposable single-dose vials; tablets with appropriate composition that allows a slow (1-2 minutes) dissolution in the mouth in contact with saliva. In Europe, SLIT is prescribed in general for one or a few allergens, and mixtures are less used, though there is no immun…
Management of severe perioperative bleeding: guidelines from the European Society of Anaesthesiology.
2013
The aims of severe perioperative bleeding management are three-fold. First, preoperative identification by anamesis and laboratory testing of those patients for whom the perioperative bleeding risk may be increased. Second, implementation of strategies for correcting preoperative anaemia and stabilisation of the macro- and microcirculations in order to optimise the patient's tolerance to bleeding. Third, targeted procoagulant interventions to reduce the amount of bleeding, morbidity, mortality and costs. The purpose of these guidelines is to provide an overview of current knowledge on the subject with an assessment of the quality of the evidence in order to allow anaesthetists throughout Eu…
Ten important articles on noninvasive ventilation in critically ill patients and insights for the future: A report of expert opinions
2017
Background Noninvasive ventilation is used worldwide in many settings. Its effectiveness has been proven for common clinical conditions in critical care such as cardiogenic pulmonary edema and chronic obstructive pulmonary disease exacerbations. Since the first pioneering studies of noninvasive ventilation in critical care in the late 1980s, thousands of studies and articles have been published on this topic. Interestingly, some aspects remain controversial (e.g. its use in de-novo hypoxemic respiratory failure, role of sedation, self-induced lung injury). Moreover, the role of NIV has recently been questioned and reconsidered in light of the recent reports of new techniques such as high-fl…
