Association between sleep disorders and subsequent chronic spontaneous urticaria development: A population-based...

Area of Science:

• Dermatology
• Sleep Medicine
• Epidemiology

Background:

• Chronic spontaneous urticaria (CSU) is often associated with sleep disorders (SDs) due to pruritus.
• The potential role of SDs in the development of CSU requires further investigation.

Purpose of the Study:

• To investigate the association between sleep disorders and the subsequent development of chronic spontaneous urticaria.
• To determine if sleep disorders increase the risk of developing CSU.

Main Methods:

• A retrospective, population-based matched-cohort study using a Taiwanese database.
• Included 105,892 patients with new-onset SDs and 105,892 matched controls, followed for 10 years.
• Cox proportional hazard regression analysis was used to assess CSU risk.

Main Results:

• The incidence of CSU was 53.4 per 10,000 person-years in the SD cohort versus 28.3 per 10,000 person-years in the control cohort.
• Patients with SDs had a significantly higher risk of developing CSU (adjusted hazard ratio = 1.83).
• Comorbidities were more prevalent in the SD cohort.

Conclusions:

• Sleep disorders are associated with an increased risk of developing chronic spontaneous urticaria.
• This study highlights a potential bidirectional relationship between SDs and CSU.
• Further research into the mechanisms linking SDs and CSU is warranted.
