Active clinical trials for "Chronic Urticaria"

The aim of this study is to validate a previously developed patient reported outcome instrument (in project UCT-D) to assess disease control in chronic urticaria patients (Urticaria Control Test - UCT) of age 12 and older.

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

Hives affects 10-25% of the population worldwide at some time during their lifetime. Hives are itchy transient swellings of the skin lasting 4-36 hours. Chronic urticaria is defined as hives that have been ongoing for six weeks or more. Patch testing is performed to diagnose allergic contact dermatitis, and if contact allergens are found via patch testing, patients can often be cured of their dermatitis. However, patch testing is currently not routinely performed in the evaluation of patients with chronic idiopathic urticaria. Our hypothesis is to see if contact allergens can be identified with patch testing in patients with chronic urticaria, and, if any allergens are identified, to see if avoiding these contact allergens will make the chronic urticaria go away.

The goal of this study is to describe the prevalence and the type of parasite in patients with a chronic spontaneous urticaria as well as to describe the associations between parasitic disease and the characteristics of the patients, for example eosinophilia.

Non interventional study collecting patient reported outcomes. The study aims to assess the disease burden of chronic urticaria patients and to record the therapies used in daily clinical practice in the UK and the impact they have on the quality of life and work productivity of individual patients.

Chronic urticaria affects up to 1% of the population. Chronic urticaria refractory to updosing antihistamines can benefit from OMALIZUMAB, which is an anti-IgE IgG1 monoclonal antibody administrated every 4 weeks subcutaneously which represents a cost of nearly 800€/month excluding nurse fees. Efficacy and good tolerance have already been demonstrated in real-life large cohorts of patients. A 6 months treatment duration is proposed before evaluating the efficacy and discontinuating the treatment in the absence of adequate response. Mean duration of chronic urticaria is 3 to 5 years with high standard deviations. Therefore, optimal duration of treatment with OMALIZUMAB is unknown and discontinuation modalities differ between physicians. The aim of this study is to evaluate the mean duration between initiation and first discontinuation of OMALIZUMAB in patients treated for chronic urticaria and explore the different factors influencing this duration and its outcome.

The purpose of this Managed Access Program (MAP) Cohort Treatment Plan is to provide access to remibrutinib for adult patients with chronic spontaneous urticaria (CSU)

Global Cohort Managed Access Program (MAP) to provide access to ligelizumab (QGE031) for chronic spontaneous urticaria (CSU)

Chronic idiopathic urticaria (CIU) is a common form of chronic urticaria in which the cause is not detected after intensive clinical and laboratory investigation.In view of the current data, it was suggested that at least part of the patients with CIU have an autoimmune process.This study is designed to investigate the mechanisms involved in the regulation and activation of the immune cells in patients with CIU and corelate them with disease activity

Urticaria is one of the most frequent presenting complaints in dermatology, allergy, and emergency departments. The term chronic urticaria (CU) is understood as the appearance of recurrent wheals more than twice a week for over 6 consecutive weeks .Urticaria is not a single disease but a reaction pattern that represents cutaneous mast cell degranulation, resulting in extravasation of plasma into the dermis. The incidence of chronic urticaria is unknown, but it is thought to occur in 0.1%-3% of the population
