Aaeroallergen Immunotherapy (AIT) is indicated in the treatment of allergic rhinitis and asthma, and has shown efficacy to control symptoms and induce immunomodulatory changes that support post discontinuation efficacy. Data from clinical trials provides founding for its efficacy and safety profile, but the therapy needs to be withheld for a minimum of 3 years, with modalities that imply daily or near daily administration of a sublingual extract, or subcutaneous injections, every 4 to 6 weeks. This treatment regimen often faces other limitations such as cost, patient´s lack of knowledge regarding efficacy/safety, or potentiality of adverse reactions. These factors have been pointed out as main reasons for a reported low level of treatment adherence in real life. While overall literature data on treatment adherence ranges widely, from 6% to 93% of patients finalising the minimum of 3 years, current data from precise German registries inform of persistence at 3 years being very low, varying from 5.2% to 18.2% with differences depending on extract, route and patient´s age. Surprisingly, even if the Scientific community acknowledges patient adherence as a very relevant weak point, there´s paucity of structured strategies to tackle this issue, and those available, have mostly been developed in single centers, for periods below the 3 years of AIT recommended duration. In the era of technology, and with the spreading of mobile applications (App), new approaches are currently ongoing to counteract this important drawback . In this landscape, this study aims at creating a new App that will be thoroughly tested in a prospective long-term randomized trial, to improve AIT persistence.
NCT04648930
This was a multicenter, uncontrolled, open-label, special drug use study to investigate the safety and efficacy of Xolair by collecting data in its clinical setting in patients with severe to most severe seasonal allergic rhinitis aged ≥ 12 years and \< 18 years whose symptoms were inadequately controlled despite to conventional therapies and used Xolair.
NCT07436208
Soluble suppression of tumorigenicity 2 (sST2), a decoy receptor of interleukin-33 (IL-33), involved in allergic inflammation. Objectives: This study explored serum sST2 as a biomarker for disease activity and for predicting clinical response to sublingual immunotherapy (SLIT) in patients with house dust mite (HDM) induced AR. Methods: This study included 54 patients with moderate-to-severe AR (MSAR) and 54 healthy controls (HC). Serum sST2, total IgE, HDM-specific IgE, and eosinophil counts were measured. Serum levels of miR-223 were assayed using real-time PCR. Clinical severity was assessed using the total nasal symptom score (TNSS) and visual analogue scale (VAS). MSAR patients received SLIT for 6 months. Treatment response was defined by ≥30% reduction in symptom and medication scores.
NCT07308288
Respiratory allergic diseases, namely asthma and allergic rhinitis (AR), are among the most common chronic pediatric conditions with prevalence continuing to rise over last decades and are leading healthcare costs. Epidemiological trends show high rates in young children, aged under 10 years, significant comorbidity between conditions (asthma and AR), and a rising recognition of lifestyle's role in microbial, epithelial barrier and immune system dysfunction which collectively drive type 2-driven airway inflammation, the hallmark feature of allergic respiratory diseases. Strategies aiming to reduce allergy outcomes have included dietary interventions during the pediatric age with immunonutrition and postbiotics. Immunonutrition uses specific nutrients to support the immune system, while postbiotics use microbial-derived compounds to modulate microbiome, epithelial barrier and immune function, and they can work together by modulating the gut-immune axis to reduce inflammation and to promote immune tolerance also through epigenetic mechanisms. Vitamin D, DHA, quercetin, perilla frutescens, fructooligosaccharides and DHA have been indicated as promising food supplements for and effective immunonutrition action against allergy. Similarly, postbiotics-non-viable microbial preparations with demonstrated biological activity-such as heat-inactivated Lactobacillus rhamnosus GG (LGG) and the gut microbiome-derived metabolite butyrate have been shown to strengthen epithelial barrier integrity, modulate cytokine secretion, and promote regulatory immune responses. Collectively, these findings suggest that targeted nutritional or microbial-derived interventions capable of reinforcing epithelial barrier function and restoring regulatory immune pathways may offer a promising adjunctive strategy for pediatric allergic airway diseases. Despite the expanding mechanistic evidence, clinical trials evaluating multi-component immunomodulatory nutritional interventions in children with asthma or allergic rhinitis remain scarce, and the translational relevance of these mechanistic pathways has not yet been thoroughly tested in controlled pediatric studies. Based on this rationale, we designed a clinical study to evaluate the clinical and immunological effects of a multi-component supplement containing immunonutritional compounds and postbiotics focusing on symptom control and immunoregulatory biomarkers in PBMCs from children with allergic asthma and AR.
NCT06603935
This study aims to evaluate the effectiveness of digital tools in managing allergic rhinitis (AR) in primary care settings. AR is a common condition that affects many people's quality of life. The study will test whether digital tools, such as the QHSLab platform, can help patients better control their symptoms, improve adherence to treatment, and enhance overall well-being. The trial will compare two groups: one using standard care and the other using both standard care and digital tools. Participants will be monitored over 12 months, and the study will measure changes in symptom severity, treatment adherence, quality of life, and healthcare usage. The study will also gather feedback from patients and healthcare providers about their experience with the digital tools. The digital tools used in this study are designed to help patients manage their AR more effectively by providing regular symptom assessments, medication reminders, and personalized feedback based on their health data. This summary ensures the information is clear and straightforward for patients, families, and healthcare providers while maintaining compliance with IRB guidelines.

The primary objective of this 5-year study is to demonstrate non-inferiority of children compared to adults by exploring long-term effectiveness after treatment with TA Bäume (trees) and TA Gräser (grass) following a perennial posology.
NCT01992835
After an allergen challenge, the allergic inflammatory response disappears spontaneously. The initiation of the resolution of the inflammatory response is now recognized as a dynamic process, involving active biochemical programs that enable inflamed tissues to return to homeostasis. Recent data established key roles of different specific lipid mediators in the endogenous counter-regulation of inflammation and activation of resolution. Only little is known about kinetics of these specialized pro-resolving lipid mediators during acute allergic inflammation. Therefore, the primary propose of our study is to characterize the temporal evolution of cellular inflammation and specific lipid mediators after allergen challenge.
NCT01425632

NCT05637710
AR is the most common respiratory disease worldwide and is clinically defined by the presence of nasal symptoms induced by exposure to allergens, particularly nasal obstruction and pruritus, runny nose and sneezing. The treatment purpose is to prevent or alleviate symptoms as safely and effectively as possible. Above all, it is recommended that patients avoid contact with allergens to which they are sensitive. However, this is often not enough, and pharmacological interventions are often required. H1 antihistamines (anti-H1) are considered first-line drugs in the treatment of AR1. These drugs effectively relieve symptoms of the immediate phase of AR, such as nasal pruritus, sneezing, runny nose and associated eye symptoms, and partially the nasal blockage characteristic of the late phase of the disease. Due to their excellent safety profile and therapeutic advantages in the treatment of AR, second-generation anti-H1 drugs, such as levocetirizine, should always be prioritized over older compounds in all age groups1. The combined administration of an antihistamine and an oral decongestant was shown to b more effective than the administration of an antihistamine alone for the relief of AR-associated nasal obstruction1. Levocetirizine is an active pharmaceutical ingredient (API) registered in the country as a monodrug for oral administration at a dose of 5mg. Pseudoephedrine is not marketed as a monodrug for oral use in our area, but it is registered in FDC with antihistamines, which is why there is no comparator arm treating with pseudoephedrine only. These products are widely used and their efficacy and safety are well known in daily clinical practice in the proposed indication. Once the absence of a pharmacokinetic interaction between levocetirizine and pseudoephedrine has been confirmed in relative bioavailability studies (RBA), this phase 3 study will be conducted in order to demonstrate the superiority of FDC levocetirizine 5mg / pseudoephedrine 240mg over levocetirizine 5mg administered alone in the symptomatic treatment of AR, particularly with regard to nasal obstruction. The registration seeks to provide a new effective and safe therapeutic option to address these cases.

NCT06732414
Background: Allergic or sinus diseases can affect the skin, sinuses, airways, and other parts of the body. Examples include pollen and environmental allergies, food allergies, asthma, and eczema. To learn more about how to prevent and treat these diseases, researchers need to study data, blood, fluid, and tissue samples from people affected by them. Objective: To collect data, blood, fluid, and tissue samples from people with allergic or sinus diseases. Eligibility: People aged 3 to 100 years with allergic or sinus diseases. Design: Participants will have at least one clinic visit, and most participants will have a baseline visit, annual visit, and an end of study visit. The duration of the study is 1 to 3 years. During the first clinic visit, the following procedures will be done to collect data, blood, fluid, and tissue samples: * Blood will be collected. * Cells and fluid may be collected from the inside of the nose using a long swab, and a small piece of skin may be scraped from inside the nose. * Skin cells will be collected by rubbing with a cotton swab. * A urine sample will be collected. * Allergy skin prick tests. Allergy-causing substances will be placed on the back or arm and the skin underneath gently scratched. If the participant is allergic to the substance, the skin may become red, itchy, and swollen locally ( at the site of the test). * Lung function test. Participants will breathe into a machine that measures the air moving in and out of their lungs. * If, as part of their routine care, participants are undergoing procedures such as having nasal polyps removed, skin tissue samples taken, or gastrointestinal biopsies, additional tissues may be collected for this study. * Participants will complete online questionnaires regarding their symptoms, health, and life. Participants may return for more visits for up to 3 years.

Allergic rhinitis in children is common. According to the international study of asthma and allergies in childhood (ISAAC) phase III, the global prevalence of allergic rhinitis among children is increasing to 40.1% and the prevalence of allergic rhinitis in Bangkok area in 2018, among children aged 6-7 and 13-14 years was 16.32%. This disease is a global health problem affecting quality of life of patients in daily life, work, study and sleep. Intranasal corticosteroid is the most effective treatment for allergic rhinitis. From real world evidence; most of allergic rhinitis patient use the drug when symptoms worsen. In children, the use of intranasal corticosteroid may cause minor local side effects such as dryness, burning sensation or epistaxis. In some intranasal corticosteroid, long-term use may result in decreased growth compared to placebo which make parents concern. The investigators interested in studying the efficacy of intranasal corticosteroid comparing between daily use and as needed use in children with allergic rhinitis. To study the appropriate form of treatment to increase cooperation. Patient will have a better quality of life and reduce the risk of side effects from prolonged use of intranasal corticosteroid. From the literature review, it was found that most studies were conducted among adult patients with seasonal allergic rhinitis In Thailand in 2020, Thongngam et al. studied the efficacy of intranasal corticosteroid was compared between daily use and as needed use in adult patients with perennial allergic rhinitis. The results of the study concluded that the daily use group can reduced more TNSS (total nasal symptoms score) but was not statistically significant and had a greater increase in peak nasal inspiratory flow (PNIF) compared to as needed group. Interestingly, the quality of life assessment (RCQ-36 score) in both2 groups improved equally, In as needed group, the cumulative dose was 51% lower than the daily dose group. The investigators want to compare the efficacy of intranasal corticosteroid between daily versus as needed use in children with perennial allergic rhinitis which had not been studied before.

Clinical efficacy and tolerability for allergen specific immunotherapy (AIT) with Itulazax (birch pollen extract tablet) is well established. Allergen challenges are used by clinicians to confirm correct diagnosis and by researchers to evaluate the efficacy of different interventions, eg. AIT. The challenge is performed by using a specific controlled administration schedule of an allergen product in the shock organ (nose, eye, or airway) and then monitor the result. Nasal Allergen Challenge (NAC) is the most common allergen challenge used. Aquagen SQ (birch pollen extract) has since decades been golden standard for this purpose, but production of this product ended 2019. Clinicians as well as researchers are now in need for an alternative product. To evaluate a new method for NAC would be of value from a clinical- and research perspective. From a Nordic perspective a NAC study with dissolved Itulazax would be of special interest since birch allergy is a dominant allergen in the region. In a recently published article it was shown that dissolved Grazax and Aquagen Phleum pratense gave comparable result used in grass allergic patients. Therefore, it seems reasonable to assume that the same method could be used with dissolved Itulazax. The aim of this clinical trial is to evaluate the feasibility of nasal allergen challenge tests with dissolved Itulazax tablets. The main benefit of this proposal is that the allergen composition of the provocation test product is the same as the final product to be treated with. This is likely to increase the treatment motivation of the patient. In addition, the dissolving process is easier for the physician compared to the dissolving of the previously used Aquagen.
