State of the Art of Chronic Spontaneous Urticaria in Italy: a Multicentre Survey to Evaluate Physicians' and Patients' Perspectives

Objective: To assess the clinical status of chronic spontaneous urticaria (CSU) and understand treatment approaches in Italy through specialists who treat CSU (dermatologists and allergy specialists) and CSU patients' experience.

Design: Multicentre survey.

Setting: Online structured questionnaires (one for physicians and one for patients).

Participants: Physicians and patients with CSU in Italy.

Interventions: None.

Primary/secondary Outcomes: Physician and patient attitudes/experiences.

Results: Survey results from 160 allergy and 160 dermatology specialists show that specialists see a median of 40 (IQR 20-80) patients with CSU/year. While most specialists (56%) know the CSU guidelines, only 27% use them regularly (36% of allergy specialists vs 18% of dermatologists). This is reflected in treatment choices with differences between physicians who use guidelines regularly and those who do not: 91.6% vs 71.7% choose standard-dose, non-sedating antihistamines as first-line treatment; 85.9% vs 56.0% select up-dosing for second-line treatment and 65.3% vs 37.2% add leukotriene receptor antagonists or H-antihistamines as third-line treatment. The diaries from 1385 patients highlight that, regardless of treatment regimen, 29.4% of currently treated patients are refractory to therapy. Specialists aim to resolve symptoms and only 7.8% report improving quality of life (QoL) as a priority. Only 16.6% of specialists are familiar with and use the Urticaria Activity Score while 46.9% do not know it. Overall, 537 patients with CSU were surveyed (median age 37 years, IQR 30-46; 44.3% men; median disease duration 5 years, IQR 3-20). Approximately 62% confirm that CSU negatively impacts their QoL. Patients also complain of difficulties in getting information and support: <5% of medical centres provide patient support services.

Conclusions: In Italy, the gap between guideline-based care and QoL-related needs in CSU patients affects treatment satisfaction. This information could be used to improve the management of CSU in Italy.
