Active clinical trials for "Urticaria"

This study is based on a survey about the patient centered care situation and health-related quality of life of patients with diagnoses Psoriasis, Urtikaria or Lupus erythematodes. Detection of relevant parameters of quality of life by these patients serves for the detection of psychosocial burden of the mentioned skin diseases, thus gaining an increasing importance for prospective economic issues. This survey is a behaviorally based questionnaire for patients with the above diseases and addresses activities such as sleep and rest, mobility, recreation, home management, emotional behavior, social interaction, and the like.

The investigators will evaluate sensitization to animal allergens and allergic symptom during contacting animal allergens in Korean veterinary researchers who attend their annual conference. The investigators will compare sensitization to animal allergen and other clinical and occupational factors between subjects who suffer from allergic symptom during contacting animal and those who do not.

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.

One of the proposed mechanisms in CU is autoimmunity. It was shown by a positive response to autologous serum skin test (ASST)in almost half of chronic urticaria (CU) patients. IL-18 also play a role in autoimmune disorders. The investigators aim was to investigate the relationship of ASST and IL-18 in CU and respiratory allergic diseases.

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.

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.

The aim of the project is to develop a patient reported outcome instrument to assess disease control in chronic urticaria patients (Urticaria Control Test - UCT) of age 12 and older.

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
