Oleic Acid-Injection in Pigs As a Model for Acute Respiratory Distress Syndrome
2018
The acute respiratory distress syndrome is a relevant intensive care disease with an incidence ranging between 2.2% and 19% of intensive care unit patients. Despite treatment advances over the last decades, ARDS patients still suffer mortality rates between 35 and 40%. There is still a need for further research to improve the outcome of patients suffering from ARDS. One problem is that no single animal model can mimic the complex pathomechanism of the acute respiratory distress syndrome, but several models exist to study different parts of it. Oleic acid injection (OAI)-induced lung injury is a well-established model for studying ventilation strategies, lung mechanics and ventilation/perfus…
INSAID Variant Classification and Eurofever Criteria Guide Optimal Treatment Strategy in Patients with TRAPS: Data from the Eurofever Registry
2021
Contains fulltext : 231528.pdf (Publisher’s version ) (Closed access) BACKGROUND: TNF receptor-associated periodic syndrome (TRAPS) is a rare autoinflammatory disease caused by dominant mutation of the TNF super family receptor 1A (TNFRSF1A) gene. Data regarding long-term treatment outcomes are lacking. OBJECTIVE: To assess correlations of genotype-phenotypes in patients with TRAPS, as defined by the International Study Group for Systemic Autoinflammatory Diseases (INSAID) classification and Eurofever criteria, with treatment responses. METHODS: Data from 226 patients with variants of the TNFRSF1A gene and enrolled in the Eurofever registry were classified according to the INSAID classifica…
Efficacy of allergen immunotherapy in reducing the likelihood of developing new allergen sensitizations: a systematic review
2017
Background Guidelines and position papers indicate that allergen immunotherapy (AIT) is the only disease-modifying treatment, including prevention of the onset of new allergen sensitizations. However, this preventive effect was shown by only a few observational studies. Our aim was to systematically review the efficacy of AIT in preventing the onset of new allergen sensitizations. Methods Computerized bibliographic searches of MEDLINE, EMBASE, and the Cochrane Library (through June 2015) were supplemented with manual searches of reference lists. Observational studies or randomized controlled trials with a long-term observation period were included. Paired reviewers extracted data about stud…
Helicobacter pylori Infection and Risk Factors in Relation to Allergy in Children
2017
Purpose To analyze presence of Helicobacter pylori infection and environmental risk factors among children with and without allergy. Methods Parents of children at primary health care centres/kindergartens and allergologist consultation were asked to answer a questionnaire and to bring a faecal sample. H. pylori infection was detected by monoclonal stool antigen test. Prevalence of H. pylori infection and risk factors were compared between individuals with and without allergy using χ2 test, ANOVA test and parameters and logistic regression. Results Among 220 children (mean age, 4.7 years; ±standard deviation 2.3 years) H. pylori positivity was non-significantly lower among patients with all…
Feasibility of the Allergy Questionnaire for Athletes (AQUA © ) in pediatric age
2018
A burden of respiratory and allergic symptoms up to almost 60% has been observed in young and adult athletes, influencing physical performances1 . The Allergy Questionnaire for Athletes (AQUA©) is a validated screening tool for the prediction of the atopic status in adult athletes2 ; it was recently tested in Belgian young elite athletes (12-14 years old)3 , but its actual feasibility and suitability for children and adolescent was not evaluated. Indeed, there is evidence that children are prone to employ "satisficing" response strategies, answering every question positively/negatively, or simply not answering4 . Therefore, the present cross-sectional survey was carried out to assess feasib…
Allergy to Polyethilenglicole of Anti-SARS CoV2 Vaccine Recipient: A Case Report of Young Adult Recipient and the Management of Future Exposure to SA…
2021
The main contraindication to the anti-SARS CoV2 vaccine is an anaphylactic reaction to a vaccine component. The need to vaccinate allergic people who are at higher risk can be of public health interest and this report shows a case of an allergic reaction to PEG of a HCW who had received the first dose of anti-SARS CoV2 vaccine. For 5 h after the administration of the vaccine, she had the appearance of erythematous spots on the face and neck, and a feeling of a slurred mouth and hoarseness. In order to treat the event, she was administered 8 mg intravenous dexamethasone, 1 vial intravenous chlorphenamine maleate, 250 mL intravenous 0.9% NaCl, and conventional oxygen therapy (2 L/min) with co…
The geriatric asthma: pitfalls and challenges
2016
Historically, asthma has been envisioned as a disease of younger ages. This has led to the assumption that respiratory symptoms suggestive of asthma occurring in older ages are to be attributed to conditions other than asthma, mainly COPD. Old observational reports and new epidemiological studies confirm that asthma is as frequent in older as it is in younger populations. Nevertheless, under-recognition, misdiagnosis and under-treatment are still relevant issues. The characterization of asthma in the aged suffers from the fact that there has been very little original research in this field. Indeed, geriatric asthma is often excluded from clinical trials because of age and comorbidities. The…
Fractional exhaled nitric oxide is associated with more severe asthma
2018
Fractional exhaled nitric oxide (FeNO) levels are used as a marker of airway inflammation. The aim of the present work was to evaluate a possible relationship between FeNO and parameters of asthma control and severity in different asthma phenotypes. FeNO was evaluated in 200 asthma patients (37% male, mean age ± SD 54±15 years, 19% controlled (GINA), 30% treated with oral corticosteroids (OCS), median FEV1 (interquartile range) 2,05 L (1,49-2,70), 74% pred. (56-90%)), together with other asthma characteristics (lung function, asthma control, allergies, serum IgE, serum ECP, and blood eosinophils). Patients with poorly controlled asthma had significantly higher FeNO values (ACQ-5≥1.5 vs. 70%…
Patients with allergic and eosinophilic asthma in the German severe asthma registry
2015
Targeted treatment strategies for asthma require a precise diagnosis of phenotypes. 308 adult patients (age mean±SD: 50.3±13.5yrs) with severe asthma from the German Severe Asthma Registry (www.german-asthma-net.de) were evaluated based on history of allergy symptoms, results of skin prick tests, total/specific IgE, and blood cell differentials. 121 patients (39%) showed typical signs of allergic asthma including allergic symptoms and a positive skin prick test and/or specific IgE with no elevated blood eosinophils (median total IgE: 222 (range 4-4023) IU/ml, eosinophils: 128 (0-295)/µl, FeNO: 23 (7-300) ppb). 53 (43.8%) of these patients were treated with omalizumab. 50 patients (16%) had …
Tachykinin-, calcitonin gene-related peptide-, and protein gene product 9.5-immunoreactive nerve fibers in alveolar walls of mammals.
1991
The presence and distribution of the presumed pan-neural marker protein gene product 9.5 (PGP)- and peptide-immunoreactive (ir) nerve fibers in alveolar walls of various species was investigated by light microscopic single and double staining immunohistochemistry. PGP-, tachykinin (TK)-, and calcitonin gene-related peptide (CRGP)-ir fibers were sparsely distributed in a similar pattern in alveolar walls of all species investigated. No vasoactive intestinal peptide-, peptide histidine isoleucine-, galanin-, and opioid-ir nerve fibers could be detected. PGP-ir fibers outnumbered those staining for TKs and CGRP. There was partial coexistence of PGP and TK as well as of TK and CRGP. PGP-, TK-, …
