Patients with chronic urticaria (CU) prioritize rapid symptom relief and ease of use, but safety becomes paramount when adverse effects increase. These patient values are crucial for improving CU treatment guidelines and research.
Area of Science:
- Dermatology
- Allergy & Immunology
- Patient-Reported Outcomes
Background:
- Patient and caregiver values are essential for effective clinical management.
- Current practice parameters for chronic urticaria (CU) aim to incorporate patient preferences.
- A systematic review on patient and caregiver values for CU management was previously unavailable.
Purpose of the Study:
- To synthesize patient and caregiver values and preferences regarding chronic urticaria (CU) treatment options.
- To inform updates to clinical practice guidelines for CU management.
Main Methods:
- Systematic literature search across multiple databases (MEDLINE, Embase, PsycINFO, CINAHL).
- Independent screening, data extraction, and risk of bias assessment by paired reviewers.
- Qualitative synthesis using thematic and inductive content analysis, with evidence certainty rated using the GRADE-Confidence in the Evidence from Reviews of Qualitative Research approach.
Main Results:
- 18 studies involving 28,497 participants were included.
- Patients highly value rapid (2 days-2 weeks) and long-term symptom improvement, preferring oral/topical treatments over injections or infusions.
- Patients accept minor burdens for symptom relief but prioritize safety and tolerability as adverse effect risks increase.
Conclusions:
- Patients with CU prioritize immediate and sustained relief from hives, itching, and swelling.
- Preference shifts towards avoiding harms and burdens when the risk or severity of adverse effects escalates.
- Findings provide a resource to enhance the trustworthiness of CU recommendations and guide future research and management.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
