NCT03861910
Food allergy is a common chronic condition in childhood. Recent studies have suggested that the natural history of food allergy has changed during the last two decades, with an increased prevalence, severity of clinical manifestations, and risk of persistence into later ages. The increased food allergy prevalence in children has an important economic impact, with significant direct costs for the healthcare system and even larger costs for the families of food-allergic patients. In addition, children with food allergies are at increased risk to develop other allergic manifestations later in life. According to a recent study, children with a food allergy are 2 to 4 times more likely to develop other atopic manifestations such as asthma (4.0 times), atopic eczema (2.4 times), and respiratory allergies (3.6 times), compared to children without a food allergy. Cow's milk allergy is among the most common food allergy in early childhood, with an estimated prevalence of 2% to 3%. It has been previously showed that in children with cow milk allergy, an extensively hydrolysed casein formula supplemented with the probiotic Lactobacillus rhamnosus GG induced higher tolerance rates compared to extensively hydrolysed casein formula without Lactobacillus rhamnosus GG and other formulas. These findings were consistent with those of a 1-year follow-up study performed in the US that showed better outcomes using an extensively hydrolysed casein formula+Lactobacillus rhamnosus GG vs. an extensively hydrolysed casein formula or amino acid-based formula for the first-line dietary management of cow milk allergy. In addition it has been recently demonstrated that extensively hydrolysed casein formula + Lactobacillus rhamnosus GG reduces the incidence of other atopic manifestations and hastens the development of oral tolerance in children with IgE-mediated cow milk allergy. The present randomized controlled trial (RCT) was designed to test whether different dietary interventions could influence the occurrence of other atopic manifestations in children with IgE-mediated cow milk allergy.
NCT05192720

NCT06151938
The study is a single-center, observational design with a 12-month duration. Approximately 100 Chinese adult (18-65 years old) and adolescent (12-17 years old) with moderate to severe house dust mite (HDM) allergic rhinitis (AR) with or without allergic asthma (AA) who are newly prescribed ACARIZAX® will be recruited for evaluation of the relevance of measurement instruments. The instruments referred to three patient-report scales of allergic rhinitis symptom and quality-of-life including the Daily symptom score (DSS), Standardised rhinoconjunctivitis quality-of-life questionnaire \[RQLQ(S)\], and Visual analogue scale (VAS). Other data will be collected to evaluate the effectiveness and safety of ACARIZAX® under real-world clinical practices.
NCT03654976
The trial aims to demonstrate efficacy of the House Dust Mite SLIT-tablet versus placebo as add-on treatment in children and adolescents (5-17 years) with House Dust Mite allergic asthma based on clinically relevant asthma worsening.
NCT03213184
The environment during the prenatal period and in early life is a major contributor to the risk of developing childhood asthma. Birth cohort studies from single research centers have identified several factors that affect the risk for developing childhood asthma, including being exposed in early life to allergens, pollutants, viruses and bacteria, and psychosocial stress. Despite such advances, further progress in understanding the root causes of asthma have been hampered by the small size of previous studies, which makes it difficult to: 1) identify asthma risk factors with certainty, 2) know how environmental factors across the United States (U.S.) affect asthma, and 3) whether there are critical ages when pregnant mothers, infants and young children are particularly susceptible to these influences. Furthermore, different research groups tend to use different methods to study asthma, making it difficult to either compare or pool findings. One other challenge is that there are several types (i.e. phenotypes, endotypes) of childhood asthma, but these are poorly understood. To help overcome these challenges, investigators leading 12 asthma birth cohorts across the U.S. have established the Children's Respiratory Research Workgroup (CREW) consortium. CREW proposes to identify specific types of childhood asthma, develop an understanding of what early life environmental influences cause these different types of asthma and when, and identify targets for future efforts aimed at preventing childhood asthma.

Exercise capacity will be assessed using cardiopulmonary exercise testing (CPET). Physical activity and sleep quality will be assessed with a wearable physical activity and sleep monitor. The study will consist of a 4-week screening period, a 24-week treatment period, and a 4-week safety follow-up. Approximately 60 participants will be enrolled, and omalizumab will be dosed according to the approved United States Package Insert (USPI) dosing table.
NCT04878237
IgE-associated allergy is a hypersensitivity disease affecting more than 40% of the population in industrialised countries. Recently the kinetics of change of clinical and immunological parameters (e.g. nasal blockage and cytokine profiles) in response to allergen exposure have been described. Additionally through recent placebo controlled studies it has become clear that the response of certain cytokines can not only be triggered by allergen exposure but also mechanically e.g through the insertion of nasal swabs for collection of cytokines. However it is not clear to what extent the mechanically triggered cytokine responses may differ between healthy, allergic and asthmatic patients who have been shown to have different cytokine profiles in their nasal secretions and varying impairment of their respiratory epithelium. As collection devices for nasal secretions are frequently used in clinical studies, the investigators aim to assess the impact of mechanical stimulation by frequent cytokine sampling on the cytokine profile.
NCT04902989
In Latin America and the Caribbean, more than 100 million people are exposed to higher levels of pollution than those recommended by WHO. The objective of the study is to determine the relationship between exposure to environmental pollutants and the prevalence and exacerbation of respiratory allergy. It is an observational, prospective, longitudinal and descriptive study that will include subjects older than 6 years who come to the consultation of the Regional Center for Allergy and Clinical Immunology with a diagnosis of respiratory allergy, positive skin tests and who live in Monterrey and its metropolitan area. After verbal assent, the subject's address and work area will be registered, the Rhinitis Control Assessment Test and the Asthma Control Test as well as spirometry will be made. The geolocation of industries and avenues near the address and work area of subjects will be carried out, as well as the determination of pollutants and pollens by the Integral Monitoring System (SIMA) and the Pollen Sense device. Subsequently, the correlation between exposure to pollutants and respiratory allergy will be analyzed. Dispersion models will be built considering pollutants and climatic factors (precipitation, wind speed, humidity and temperature). By carrying out this project, it will be possible to contribute to the identification of the factors that lead to the development and exacerbation of allergic respiratory diseases and subsequently propose the implementation of measures for their control and recommendations for prevention to the population.

The aim of this study is to validate the CSMS as a tool to assess the clinical effects of Depigoid AIT, so that the CSMS can be used in future studies as a primary endpoint as well as a comparative parameter.
NCT04567212
The GINA 2020 guidelines suggest that asthma affects approximately 300 million persons worldwide. Even if there is a specific drug treatment for each stage of disease (From mild to severe) in some patients it is not efficacy and it culd be reated to the gender difference Polymorphisms seems to be involved in asthma (allergic or not) even if no data have been published concerning the role of gender in this clinical manifestation. The aim of this study is to assess whether genetic variations involved in the genes encoding the two key leukotriene enzymes, ALOX5 and LTC4S, and CysLTR1 are implicated in the sex difference of allergic asthma in a well-characterized patient cohort.
