[Recommendations for the diagnosis and treatment of urticaria in children]
Insights
Urticaria, a common skin condition, is classified as acute or chronic. Chronic urticaria (CU) significantly impacts children
Area of Science:
- Pediatric Dermatology
- Immunology
Background:
- Urticaria is a prevalent skin disorder, affecting 25% of the population.
- Acute urticaria lasts less than 6 weeks, while chronic urticaria (CU) persists longer.
- CU affects 0.1% of the population, with a higher prevalence in women (60%).
Purpose of the Study:
- To emphasize chronic urticaria (CU) in children due to diagnostic challenges.
- To highlight the increasing prevalence of CU in pediatric populations.
- To underscore the severe quality of life impairment caused by CU in children.
Main Methods:
- Review of urticaria classification, distinguishing acute from chronic forms.
- Discussion of CU subclassification into chronic inducible and spontaneous urticaria.
- Examination of the pathophysiology, focusing on mast cell degranulation.
Main Results:
- Second-generation H1 antihistamines are the primary treatment for both acute and chronic urticaria.
- Alternative therapies are considered for patients unresponsive to initial treatment.
- CU presents significant diagnostic difficulties and negatively impacts children's quality of life.
Conclusions:
- Chronic urticaria requires focused attention due to its prevalence and impact on pediatric quality of life.
- Effective management strategies beyond first-line antihistamines are crucial for refractory CU cases.
- Further research into CU pathophysiology and treatment is warranted for improved pediatric outcomes.
Abstract:
Urticaria is one of the most common skin disorders in children. We define acute urticaria when it persists for less than 6 weeks, and chronic urticaria (CU), when it persists longer. Urticaria affects 25 % of the population; in most cases, it is acute urticaria. CU represents 0.1 %, with higher prevalence in women (60 %). CU is subclassified in chronic inducible urticaria when there is a specific external trigger and chronic spontaneous urticaria if it is not present. Although the pathophysiology is complex, mast cell degranulation is recognized as a key event. Second-generation H1 antihistamines are the first line of treatment in both, acute urticaria and CU. In unresponsive patients, other therapies will be considered. We will emphasize in CU due to the difficulty in its diagnosis, the increase in its prevalence and the severe impairment it causes in children´s quality of life.

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...
