Filter by:The present study is a 5-year follow-up of the Allergy Reduction Trial (A.R.T.) birth cohort study of 551 infants at high-risk for allergy. The A.R.T. 5-year follow-up study, aims to investigate the prolonged effect of each feeding regimen [formula-fed (exclusively or partially) with the partially hydrolyzed formula (pHF) or the standard formula (SF), or exclusively breastfed] within the first 6 months of life on the development of any allergic manifestations up to the age of 5 years. Allergic manifestations within this time period will include the presence of any of the following: atopic dermatitis, food allergies, respiratory allergies, urticaria, drug allergy and insect venom allergy. In addition, differences on growth (weight, height, BMI) will be examined.
Clinical trial with the aim to evaluate the level of agreement in wheal size measures in allergy skin prick testing (SPT) between the electro-medical device Nexkin DSPT® and the manual measurement procedure used in the daily practice.
To establish efficacy and safety of HDM sublingual Immunotherapy (HDM-SLIT) by comparing Odactra and placebo, when given sublingually for 3 years to high risk infants aged between 6 to 12 months at enrollment in preventing the development of asthma, assessed 1.5 years after discontinuation of treatment.
Anaphylaxis is a severe life-threatening reaction following exposure to an antigen. Its incidence is progressively increasing in the general population over years, especially among children. The diagnosis can be difficult, and recommendations for follow up and prescription for an emergency kit are rarely provided after emergency visit. The Investigators will evaluate the management of pediatric anaphylaxis and clinical signs of allergy in the pediatric emergency department of Montpellier University Hospital
Mold allergies are becoming increasingly important among the population. Increasing amounts of fungal spores are analyzed in air-samples because of urbanization, industrialization of food products and climate change. Mold also grows indoor and hence lead to additional health complaints. Alternaria alternata, and its only major allergen Alt a 1, is the most important fungus for allergy sufferers. Alternaria alternata can not only cause allergic symptoms but can also cause intensified asthmatic symptoms. Besides Alternaria alternata, there are over 700 other species of the genus Alternaria. The influence of these other species on allergic symptoms is poorly understood. Furthermore, prevalence and incidence of an allergy to Alternaria alternata among the Austrian population is not known. Estimates range between 1-5% among the Austrian population. This study aims to further investigate the incidence and characteristics of an allergy to Alternaria in Austria. This will be investigated with the help of participants (50 Alternaria allergy sufferers and 20 non allergic participants), spore counts in Austria and crowd-sourced symptom data.
IgE-associated allergies are consistently on the rise forming an enormous wellbeing concern and affecting about 25% of the population around the world, with main prevalence in developed nations. Birch pollen is one important allergen driving allergic conjunctivitis and rhinitis. The characteristics and location IgE producing cells in the nose and their contribution to the subsequent increase in allergen-specific IgE levels in the serum have so far poorly been investigated. Understanding these mechanisms is critical for the development of new therapeutic approaches and is thus the aim of the proposed study. Thus, the investigators plan to conduct a two-armed study of a randomized placebo-controlled double-blind nasal allergen provocation where 30 patients will be provoked with birch pollen extract (n=20) or placebo (n=10) out of the birch pollen season (October) and follow them closely for up to 4 months. Therefore, the objective of this study is to investigate the localization and characteristics of IgE producing cells in the nasal mucosa contributing to the allergen-induced boosts of specific serum IgE upon natural and controlled nasal allergen exposure.
Healsea® Children is a seawater-based nasal spray supplemented with a natural Symbiofilm® extract (0.02%) isolated from marine bacteria. Symbiofilm has antibiofilm activity against various bacterial pathogens involved in respiratory tract infections.Healsea® Children is indicated in the cleaning and moistening of nasal mucosa during common cold and rhinitis for children above 6 years. This non interventional post-market clinical investigation aimed to confirm the benefit of Healsea® Children in real life setting in children with perennial allergy who are more prone to common cold.
This is a prospective, observational clinical cohort study involving 405 children born premature (at less than 37 weeks gestation) and their mother/parent/guardian. The purpose of the study is to investigate how the microbiome (the collection of microbes in a biological site) of children develops over the first years of life and its associations with the risk of childhood health outcomes including allergies and asthma. The study will also examine how perinatal factors associate with patterns of microbiome development, and their effects on the microbiome, metabolome (the collection of metabolites in a biological sample) and immune development of this population in the first years of life.
Chronic cough is a very unpleasant symptom, significantly reduces the patient's quality of life, and bothers the neighborhood. A very common cause or co-factor of chronic cough is extraesophageal reflux (EER). The aim of the project is the precise diagnosis of EER in patients with chronic cough (in patients with a simultaneously diagnosed allergic cause and without it).
Despite its importance, there are few studies that implement the use of new technologies in the approach to patients with asthma and allergy. Therefore, the objective of this study is to evaluate the effectiveness of a telematic educational intervention in patients with allergies and / or asthma
