Background: Chronic inducible urticaria (CIndU) is the group of diseases characterized by the development of wheals, angioedema or both in response to specific triggers. According to global scientific international literature the occurrence of CIndU is 0,5% in general population and about 20-30% in all chronic urticarias. Aim: There are no statistical data of the prevalence of CIndU in Russian Federation. The aim of this research is evaluation of the epidemiology of chronic inducted urticarias. Materials and Methods: This analysis based on counts of unique cases of access to medical care in adults due to this pathology in digital EMIAS platform (inpatient and outpatient) in Moscow between 2017 and 2021, including key words search. Results: indicated that the prevalence of CIndU in Moscow is correlating with published global epidemiological data, its rates are high and tends to increase as in global practice. Limitations of this research are the lack of ubiquitous implementation of standard protocols of provocation testing in outpatient, the low percent of using validated questionnaires and systematic management of patients with CIndU. Conclusions: Further studies dedicated to this topic are a great unmet need in order to answer a wide spectrum of questions including the diagnosis process and evaluation of the the severity of CIndU, comorbid conditions and optomisation of the treatment process.
