Active clinical trials for "Chronic Urticaria"

In the majority of patients with the chronic urticaria, the etiology is unclear, leading to difficulties in treatment and high rates of recurrence. According to the International EAACI/GA2LEN/EDF/WAO Guidelines (the Dermatology Section of the European Academy of Allergology and Clinical Immunology(EAACI), the Global Allergy and Asthma European Network (GA2LEN), the European Dermatology Forum (EDF) and the World Allergy Organization (WAO) in Urticaria, using the Chronic Urticaria Quality of Life Questionnaire in a routine management is the key for a better treatment outcome. To translate this questionnaire into Thai is essential in our subject of interest in order to effectively apply it to local patients. The Thai-version questionnaire will encourage enhanced as well as impactful therapeutic options for Thai chronic urticaria patients.

The objective of this non-interventional study is to evaluate the safety of Aerius syrup in pediatric patients aged 1-5 years old with allergic rhinitis or chronic idiopathic uticaria. The patients will receive 2.5 ml (1.25 mg) once daily.

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.

A biological tool for quantitative assessment of Chronic Urticaria (CU) is still in need for monitoring biotherapies. CU is considered as a sudden degranulation of Mast cells / basophils without any identified cause. It is considered that Mast cell/basophil have an abnormally high sensitivity in CU and can be triggered with almost nothing (high irritability). In allergy, basophils degranulation can be reproduced in vitro with allergens. Anti-IgE (immunoglobulin E) antibody mimics allergen triggering of basophils in a dose dependent manner. If basophils are abnormally sensitive in CU, it should be reproduced in vitro at very low stimulation. The main objective of this project is to set up a method to evidence abnormal basophil irritability and look for clinical significance. As many markers characterize basophils in different states, researchers shall also look for a profile possibly associated with CU basophile irritability. Such tests could be useful in CU monitoring.

Chronic urticaria symptoms commonly fluctuate from day by day. Consequently the clinical presentation of a patient in each visit is not representative of the current disease status. Dermatologists are trying to integrate an evaluation process of each treatment visit regarding both clinical condition and life quality concern. The Urticaria Control Test is the key for a better treatment outcome in a routine management. To translate this questionnaire into Thai is essential in our subject of interest for offering local patients a higher well-being standard. The Thai-version test will encourage enhanced as well as impactful therapeutic options for Thai chronic urticaria patients.

Increase prevalence of thyroid autoimmunity is found in patients with chronic urticaria. About 5-34% of chronic urticaria patients is associated with the presence of thyroid autoimmunity who are euthyroid status whereas 5-10% of them with either hyperthyroidism or hypothyroidism.

This is a non-interventional, multi-country, Latin American study utilizing a prospective single-cohort design. Eligible CU patients will be enrolled in the study and will be followed for 24 months (± 6 weeks). In accordance with the observational nature of the study, there will be no interventions or interference with the routine care of the patient which will be based solely on the clinical judgment of the treating physician. However, with respect to the frequency and schedule of assessments, the schedule included in Table 7-1 will be recommended. The selection of the treatment for CU will be clearly separated from the decision to include the patient in the study, and will be made at the discretion of the treating physician in accordance with standard medical practice, the investigator's clinical judgment, and global urticarial guidelines. In order to prevent selection bias, investigators should offer enrollment to all consecutive patients meeting study criteria, likely to be available for the full duration of the follow-up period of 24 months, and willing to participate in the study. The overall objective of the study is to evaluate in real-life the CU disease burden, the current treatment patterns and the use of health care resources in patients refractory to H1-antihistamine treatment

The purpose of this study is to examine the natural history of chronic urticaria in children and to identify the predictors for chronic urticaria remission.

The primary purpose of this study is to identify and characterize novel diagnostic markers for autoimmune urticaria, a subset of chronic spontaneous urticaria. Additional aims: include the comparison of the clinical profiles of autoreactive, autoimmune and non autoreactive / autoimmune urticaria and the quality of life impairment in these subsets of chronic spontaneous urticaria.
