Active clinical trials for "Urticaria"

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

This study investigates the genetic architecture of Neutrophil-Mediated Inflammatory Skin Diseases. After collecting informed consent, all patients' clinical phenotype is graded at inclusion with a detailed case report form and a discovery cohort formed based on the certainty of diagnosis. The DNA of patients in the discovery cohort is analyzed by whole exome sequencing which identifies all protein-coding genetic variants. Subsequently, statistical burden tests are going to identify enrichment of rare coding genetic variants in patients affected by Neutrophil-Mediated Inflammatory Skin Diseases. The ultimate goal is to reveal the responsible gene(s) that may then be targets for clinical intervention.

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
