Insights
Children with chronic spontaneous urticaria (CSU) and autoimmune thyroiditis (AT) require ongoing monitoring for thyroid function and other autoimmune conditions. Early detection and management of AT may improve CSU symptoms in some pediatric patients.
Area of Science:
- Pediatrics
- Immunology
- Endocrinology
Background:
- Chronic spontaneous urticaria (CSU) and autoimmune thyroiditis (AT) can co-occur in children.
- Limited research exists on the combined prevalence and management of CSU and AT in pediatric populations.
- Existing literature suggests a higher incidence of antithyroid antibodies in children with CSU.
Purpose of the Study:
- To investigate the clinical characteristics of children diagnosed with both CSU and AT.
- To compare findings in pediatric cases with existing literature.
- To emphasize the need for further research into this specific pediatric comorbidity.
Main Methods:
- A descriptive analysis was conducted on a cohort of 15 pediatric patients with both CSU and AT.
- Data from case reports and case series were compiled and analyzed.
- Patient data included thyroid status, treatment interventions, and presence of other autoimmune conditions.
Main Results:
- Of the 15 patients, 7 (46.7%) presented with hypothyroidism, while the remainder were euthyroid.
- Hypothyroidism onset varied, preceding, coinciding with, or following CSU diagnosis.
- One hypothyroid and one euthyroid patient on l-thyroxine experienced urticaria remission; three patients received omalizumab.
Conclusions:
- Pediatric patients with CSU warrant regular screening for antithyroid antibodies.
- Close medical supervision is crucial for children with co-existing CSU and AT to monitor for additional autoimmune diseases.
- While l-thyroxine may benefit some hypothyroid patients with CSU, and omalizumab shows potential, further controlled studies are needed.
Abstract:
The aim of the study was to focus on children with both chronic spontaneous urticaria (CSU) and autoimmune thyroiditis (AT) as this topic is rarely studied in children although some publications show a higher proportion of antithyroid antibodies in children with CSU. We highlight two cases of children with both CSU and AT and compare their data with reports from the literature. Since only case reports or case series were available, we performed a descriptive analysis of 15 patients. There were 7 (46.7%) cases of hypothyroidism and the rest were euthyroid. Hypothyroidism appears before, during, and after the diagnostic of CSU. One patient with hypothyroidism and one with euthyroidism receiving l-thyroxine experienced remission of urticaria. Three patients over 12 years of age (20%) received omalizumab. Three patients (20%) had another autoimmune disease and seven (58.3%) had a family history of thyroid disease or autoimmune disease. CONCLUSION: Children with CSU need repeated testing for antithyroid antibodies. Children with both CSU and AT require close medical supervision focused on the development of other autoimmune diseases. l-thyroxine may improve urticaria in patients with hypothyroidism, but there is not enough evidence for patients with euthyroidism. Omalizumab may be of benefit in this population but well-controlled studies in children with AT and CSU are needed.
