Understanding prevalence of diseases within specific regions of a country is important for optimal allocation of healthcare resources/funds. We performed a systematic review to obtain a clearer picture of the epidemiology of psoriasis and psoriatic arthritis across and within specific regions of Italy. Prevalence of psoriasis in specific regions showed more variability (0.8-4.5%) than that in the total population (1.8-3.1%). Prevalence of psoriatic arthritis in the general population was reported for only two regions, Chiavari (0.09%) and Marche (0.42%). All other studies reported prevalence of psoriatic arthritis in patients with psoriasis in single centres and Italy-wide (4.7-47.1%). Prevalence of psoriatic arthritis was highest in patients with nail and/or scalp psoriasis and/or intergluteal/perianal region involvement. Based on current available data, these conditions appear to affect a substantial number of people and will likely have an important impact on the Italian healthcare system.
