Demographic data and clinical
and immunohistochemical markers
In total, 28 patients participated in the study, of which 25 patients
were female (89.28%). The age of the patients ranged from 22 to 77
years with a mean of 43.81 years. The duration of urticaria ranged from
3 months to 17 years with a mean of 3.14 years. The mean UAS7 was 29,
ranging from 12 to 42, with an average of 29.03.
The expression of immunohistochemical markers correlated with age, time
of urticaria evolution, and UAS7 are listed in Table 2. A significant
negative correlation was observed between the CD206 marker and the time
of CSU, the lower the tissue expression of CD206, the longer the
urticaria time.

immunohistochemical markers, age, and spontaneous urticaria time.
