Abstract
This article presents a qualified estimate of the prevalence of atopic dermatitis in Czech Republic. This search included all citizens who visited a physician in 2010-2021 and who were reported with a diagnosis of atopic dermatitis to national registry for health services (NRHZS).
The overall prevalence in this period ranged from 2.0-2.2%, of which the relative prevalence in children fluctuated between 4.7-5.8 % and the relative prevalence in adults was 1.4-1.5%. The real prevalence will probably be higher, and methodologically, persons with mild atopic dermatitis, especially children, may be missed.
Confusion with other eczema-dermatitis may also be a potential cause of the lower prevalence data for atopic dermatitis, that is why their prevalence was also monitored, but it was low. Prevalence was also followed in five age subgroups and showed an increase in adulthood, where the cause is likely to be the first manifestation of atopic dermatitis in adulthood ('adult-onset') rather than persistence from childhood.
The proportion of severe atopic dermatitis in the population of patients with atopic dermatitis in the Czech Republic (10.4%) is in line with international data. The observed low participation of physicians other than dermatologists in the care of patients with atopic dermatitis is probably due to undereporting, but it remains to be investigated.
