NCT ID: NCT06063044 Completed - Atopic Dermatitis Clinical Trials

Food-specific IgG4-guided Elimination Diets Improve Allergy Symptoms in Children

Start date: January 1, 2018
Phase:
Study type: Observational

Allergic diseases in children are major public health concerns due to their widespread and rising prevalence. The most classic pathway to trigger allergy is type I allergy mediated by immunoglobulin E(IgE), but the role of immunoglobulin G4(IgG4) in allergic diseases is still worth exploring.we have collected the data of allergic patients aged 0-14 years for retrospective cross-sectional analysis to evaluate the positive rates of total IgE, HDM IgE, FS-IgE and FS-IgG4. Meanwhile, investigators screened out patients who were treated with FS-IgG4-guided elimination diets with/without probiotics for more than 3 months to clarify the role of FS-IgG4 in childhood allergic diseases by assessing the improvement of clinical symptoms before and after treatment.

NCT ID: NCT05829499 Completed - Dry Eye Clinical Trials

PMCF Study to Evaluate Performance and Safety of "Xanoftal Next"

Start date: December 2, 2022
Phase: N/A
Study type: Interventional

Dry eye disease (DED), also called keratoconjunctivitis sicca, is a multifactorial disease of the ocular surface characterized by loss of homeostasis of the tear film and accompanied by symptoms such as ocular discomfort and visual disturbance. Patients with moderate-to-severe DED may experience a reduced quality of life due to ocular pain, difficulty in performing daily activities, and depression. Traditionally, dry eye syndrome and allergic conjunctivitis are regarded as 2 different diseases. However, recent literature has shown both conditions share similar characteristics, including several of their signs and symptoms (e.g. red, itchy, watery, and burning eyes). On the other hand, red swollen eyelids, burning sensations, ocular irritation, loss of eyelashes and misdirected eyelashes are also common symptoms of Blepharitis, an inflammatory disorder of eyelids affecting all the age and ethnic groups. First-line therapy for treating dry eye symptoms consists of over the counter (OTC) artificial tear drops, gels, ointments, or lubricants. Manufacturers have developed OTC products that appear to mimic the different layers of the tear film in order to maintain ocular hydration. For these reasons, an interventional, non-comparative, Post Marketing Clinical Follow-up (PMCF) study was planned to evaluate the performance and safety of "Xanoftal Next" used to attenuate symptoms of seasonal allergic conjunctivitis, even when associated with dry eye syndrome. The objectives of the PMCF study are confirmation of the performance, collection of additional safety data regarding expected adverse events and detection of potential unexpected adverse events associated with use of "Xanoftal Next" according to the Instructions for Use (IFU). Each subject, after signing the Informed Consent Form, will enter the screening and baseline phase (the 2 visits will coincide) during which baseline procedures will be completed. At baseline visit, the "Xanoftal Next" product will be administered to the enrolled subject. The patient will perform 2 on-site visits: V0 and V2/EOS. To monitor the safety, 1 phone contact is planned (V1) to check for potential adverse events and concomitant medications intake.

NCT ID: NCT05824000 Completed - Dry Eye Clinical Trials

PMCF Study to Evaluate Performance and Safety of "Optrex Double Action Soothing and Lubricating Drops"

Start date: June 7, 2022
Phase: N/A
Study type: Interventional

Allergic conjunctivitis (or ocular allergy) and dry eye disease (DED) are two major ocular surface disorders affecting millions of people. A typical clinical symptom of allergic conjunctivitis is itching which is also observed in subjects suffering from DED. Common symptoms of DED also include a foreign body sensation, dryness, irritation, burning sensation and visual disturbance. Patients with allergic conjunctivitis or moderate-to-severe DED may experience a reduced quality of life due to ocular pain, difficulty in performing daily activities, and depression. Gel-based artificial tear supplements may offer longer retention times and act as a supplement to the mucin layer. Carbomer (also known as Carbopol polymers) is awater-soluble polymeric resin that exhibit excellent viscoelastic and mucoadhesive properties when compared with other polymers. Carbomer is used in liquid or semisolid pharmaceutical, cosmetics, and ophthalmic formulations as rheology modifiers. Aqueous carbomer gels have been used for the treatment of dry eye and allergic conjunctivitis as they provide prolonged ocular residence time of conventional ophthalmic solutions. Furthermore, carbomer has shown compatibility with many active ingredients, good thermal stability, excellent organoleptic characteristics, and good patient acceptance. For these reasons, an interventional, non-comparative, single-center Post Marketing Clinical Follow-up (PMCF) study was planned to evaluate the performance and safety of "Optrex Double Action soothing and lubricating drops" for itchy and watery eyes. The objectives of the PMCF study are confirmation of the performance, collection of additional safety data regarding expected adverse events and detection of potential unexpected adverse events associated with the use of "Optrex Double Action soothing and lubricating drops" according to the Instructions for Use (IFU). Each subject, after signing the Informed Consent Form, will enter the screening and baseline phase (the 2 visits will coincide) during which baseline procedures will be completed. At baseline visit, "Optrex Double Action soothing and lubricating drops" will be prescribed to the enrolled subject. The patient will perform 2 on-site visits: V0 and V2/EOS. To monitor the safety, 1 phone contact is planned (V1) to check for potential adverse events and concomitant medications intake.

Safety and Efficacy of STALORAL® Birch 300 IR in a Paediatric Population With Birch Pollen-induced ARC w/o Asthma

YOBI
Start date: October 1, 2023
Phase: Phase 3
Study type: Interventional

Allergic rhinoconjunctivitis due to birch pollen is a seasonal problem which manifests as a combination of nasal symptoms (such as congestion, runny nose, sneezing, itching of the nose) and ocular symptoms (such as red, itchy and watery eyes). For several birch-allergic patients, allergic rhinoconjunctivitis occurs with an oral allergy syndrome. The purpose of this study is to demonstrate the safety and efficacy of the study drug (STALORAL Birch 300 IR) in children and adolescents with birch pollen-induced allergic rhinoconjunctivitis, with or without asthma, when treated before and during the pollen season. Approximately 699 children will participate in this study. The study will be conducted worldwide in approximately 100 medical sites in about 14 countries. The total duration of the study will be approximately 20 months.
