Introduction:
Chronic urticaria is a common disease, characterized by the development of wheals, angioedema, or both, which can be associated with several comorbidities. Most of the available studies have focused on specific common comorbidities and their association with CU, but have seldom reported the overall burden of comorbidities.
Objectives:
This study aimed to investigate and analyze self-reported comorbidities in Polish patients with CU.
Methods:
An anonymous online survey consisting of 20 questions was conducted on members of an Urticaria group on the social media platform Facebook. A total of 102 people took part in this survey. The results were analyzed in Microsoft Excel 2016.
Results:
In the group, 95.1% were females and 4.9% males, with a mean age of 33.8 years. The most common diagnosed type of urticaria was spontaneous (52.9%). Angioedema accompanied urticaria in 68.6% of the respondents, mainly those with delayed pressure urticaria (86.4%). 85.3% of respondents reported comorbidities, most often atopic diseases and allergies (49%), chronic inflammation and infections (36.3%), thyroid (36.3%) and psychiatric disorders (25.5%). Moreover, in 30.4% of patients, at least one autoimmune disease was noted. As compared to the patients without autoimmune urticaria, many more with autoimmune urticaria had a coexisting autoimmune disease (50% vs. 23.7%). Family history of autoimmune diseases was positive in 42.2%, and the familial history of urticaria and atopy was positive in 7.8% and 25.5%, respectively.
Conclusions:
The knowledge of comorbidities of chronic urticaria may support clinicians to manage and treat patients with this common condition.
