Efficacy and safety of tralokinumab in patients with severe uncontrolled asthma: a randomised, double-blind, placebo-controlled, phase 2b trial

2015

Summary Background Interleukin 13 is a central mediator of asthma. Tralokinumab is a human interleukin-13 neutralising monoclonal antibody. We aimed to assess the efficacy and safety of two dosing regimens of tralokinumab in patients with severe uncontrolled asthma. Methods We did a randomised, double-blind, placebo-controlled, parallel-group, multicentre, phase 2b study at 98 sites in North America, South America, Europe, and Asia. Patients aged 18–75 years with severe asthma and two to six exacerbations in the previous year were randomly assigned (1:1), via an interactive voice-response or web-response system, to one of two dosing regimen groups (every 2 weeks, or every 2 weeks for 12 wee…

Maximal respiratory pressure reference values for Navajo children ages 6-14

2013

Background Since anthropometric variables are critical to the creation of pulmonary nomograms for FVC, FEV1, and other volumes and capacities, it is logical that anthropometric variables also influence the values of the maximal respiratory pressures (MRPs). Since nomograms are race-specific, it is important that tribe-specific tables of normal maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) be developed. To date normal tables for MRPs do not exist for Navajo children. Objective Therefore the purpose of this study was to derive MRP normative reference values for Navajo children in the age range of 6–14 years. Methods—Participants and Measurements A cross-sectional st…

Bronchial responsiveness and airway inflammation in trained subjects

2008

We read with interest the paper by Shaaban and coworkers1 on the protective effect of physical activity against bronchial hyperreactivity (BHR) in the general population. The authors suggest that a beneficial effect of deep inspirations during exercise could account for the lower prevalence of BHR in physically active subjects compared with sedentary subjects, while the accompanying editorial2 favours an “anti-inflammatory” effect of exercise as the most plausible explanation. We have studied lung function and airway cell biology …

Transient Pulmonary Infiltrates during Treatment with Anti-Thymocyte Globulin

1999

We report the case of a 54-year-old woman with aplastic anemia, who developed transient pulmonary infiltrates following intravenous infusion of rabbit antithymocyte globulin (ATG) for 3 days. There was no other explanation than the infusion of ATG for the infiltrates. Rechallenge with ATG induced the recurrence of opacities on the chest radiograph. Although rarely involved with only 4 previous reports, ATG should be included in the list of drugs capable of inducing pulmonary infiltrates.

Early pronation, protective lung ventilation and use of awake-prone-HFNO therapy after extubation in near-fatal drowning

2023

the lack of comparative studies and of multicenter trials still makes the treatment of the lung injured drowned patient a challenge for intensivists. Although the outcome of drowned patients is related to the potential neurological sequalae, AHRF remains the main concern. Ventilation guidelines for drowning patients are mainly adapted from AHRF patients and may not reflect the needs of this particular population. Our result confirms that early pronation, in cases of lack of improvement of oxygenation, might be the correct strategy.14 In addition, HFNO and awake prone position might have a role in avoiding reintubation while maintaining adequate pulmonary gas exchanges.

Tropomyosin: A panallergen that causes a worldwide allergic problem

2021

Background: Panallergens are proteins that take part in key processes of organisms and, therefore, are ubiquitously distributed with highly conserved sequences and structures. One class of these panallergens is composed of the tropomyosins. The highly heat-stable tropomyosins comprise the major allergens in crustaceans and mollusks, which make them important food allergens in exposed populations. Tropomyosins are responsible for a widespread immunoglobulin E cross-reactivity among allergens from different sources. Allergic tropomyosins are expressed in many species, including parasites and insects. Methods: This panallergen class is divided, according to it capacity of induced allergic symp…

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…
