Evolution of Chronic Inflammatory Skin Diseases (EPICA)

July 13, 2026 updated by: Fondazione Policlinico Universitario Agostino Gemelli IRCCS
monocentric retrospective-prospective observational study evaluating the clinical evolution of common chronic inflammatory skin diseases, including atopic dermatitis, psoriasis, prurigo nodularis, chronic hand eczema, and hidradenitis suppurativa. The study will collect demographic, clinical, therapeutic, and validated clinimetric data from patients aged ≥12 years. Its primary aim is to describe changes in disease severity over time. Secondary objectives include identifying demographic, clinical, and treatment-related predictors of moderate-to-severe disease and unfavorable outcomes. Data will cover a 7-year retrospective period and a 10-year prospective follow-up.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
To describe changes over time in the clinical characteristics of the most common chronic inflammatory skin diseases (AD, PSO, HS, CHE, and PN).
Time Frame: 120 months
Change in disease-specific clinimetric scores used in routine outpatient clinical practice: Eczema Area and Severity Index (EASI); Psoriasis Area and Severity Index (PASI); Hand Eczema Severity Index (HECSI); Investigator's Global Assessment (IGA); Hurley stage; Numerical Rating Scale (NRS) for itch and sleep disturbance; Dermatology Life Quality Index (DLQI); Patient-Oriented Eczema Measure (POEM); and SCORing Atopic Dermatitis (SCORAD).
120 months
To identify potential predictors of an unfavorable or favourable disease course
Time Frame: 120 months
identification of demographic, clinical, and treatment-related factors associated with moderate-to-severe disease, as defined according to validated cutoffs for the corresponding clinimetric scores (EASI, PASI, HECSI, Hurley, DLQI, POEM, and SCORAD).
120 months
