Findings suggest different management strategies for chronic spontaneous urticaria may be warranted.
Key insights on the characteristic differences of hives in children versus adults unveiled

Key insights on the characteristic differences in chronic spontaneous urticaria (commonly presented as hives) in children versus adults have been unveiled through new research* presented at the EADV 30th Congress.

The findings reveal chronic spontaneous urticaria is less severe in children than in adults, with lower rates of angioedema and thyroid autoimmunity, supporting the idea that different management strategies may be required.

There is high prevalence of both acute and chronic urticaria in the general population, though the risk factors are unknown. Urticaria is characterised by a raised itchy rash (commonly known as hives) and occasionally angioedema, which is the rapid swelling of the skin. In chronic spontaneous urticaria (CSU) there is no specific cause or trigger, but hives are present on most days of the week, for 6 weeks or more.

Previously, it was thought that children were more likely to experience acute urticaria rather than chronic urticaria, but this study crystalises recent evidence to suggest that chronic urticaria is a common problem that affects children. There are also disparities between adults and children in terms of response to treatment, autoimmunity and disease course.

CSU is a common disease found in both children and adults, though there are differences between the two patient populations with respect to medical origins and other co-existing diseases.

Our research is focused on identifying these differences to help inform future treatment of chronic spontaneous urticaria and to provide more information on the effects of CSU on children – something which has previously been neglected in this field of research.

A retrospective analysis of 755 CSU patients (171 children, 580 adults) was conducted, with a comparison of the data performed to determine distinct characteristics between paediatric versus adult CSU patients. Findings of the study include shorter disease duration (10.0±18.2), lower occurrence of angioedema (21.8% vs 59.8%; p<0.001) and thyroid autoimmunity (8.9% vs 25.4%; <0.001) in the paediatric group vs. adult group. Moreover, paediatric CSU patients were found to respond better to antihistamines than adult CSU patients.

Resistance to antihistamines was associated with anti-TPO (the most common anti-thyroid autoantibody) positivity (p=0.02), presence of angioedema (p=0.01) and eosinopenia (an indicator of blood disorder; p<0.001) in the paediatric group while it was only associated with eosinopenia (p=0.03) in the adult group.

“Further research examining CSU in children will help towards understanding the different aspects of clinical, laboratory and therapy characteristics of the condition and why these differences exist,” said Asli Bilgic, EADV Communications Committee Member.
