Clinical Trial Summary

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.

Clinical Trial Description

1. Independently adaption of the UCT questionnaire into Thai version by using forward-backward translation by two bilingual translators. The original German version is translated into Thai by two Thai native speakers, then the study team reviews the Thai-version UCT questionnaire for items comprehensibility and integrates the first consensus version which re-translated into German by German native speaker afterwards. The comparison between the backward German version UCT questionnaire and the original UCT is carried out to find out any misconception and mistranslation in the intermediary forward version of questionnaire. The second version will be tested on 15 chronic urticaria patients to detect any misunderstanding points. Finally, this Thai-version of UCT questionnaire will be used to investigate the validity, reliability, interpretability and minimal clinical important difference.

2. To investigate the validity, reliability and interpretability of Thai-version of Urticaria Control Test, the severity of urticaria symptoms will be assessed by investigators and patients using UAS28, Patient's global assessment of disease severity (PatGA-LS), Physician's global assessment of disease control (PhyGA-LS), the UCT and DLQI questionnaire ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
