Psoriasis is present all over the world and its prevalence varies in the different populations and different geographical areas. For example, Northern European countries seem to have rates of incidence which are greater than those known for Southern Europe. However, today there is still a lack of adequate data to allow comparisons at an international level.
In Italy in 1994 the AISP (Interdisciplinary Association for the Study of Psoriasis) co-ordinated the recording of monthly case histories and clinical results relating to psoriasis in patients observed in dermatology centres homogeneously distributed throughout Italy. The results were extrapolated from the overall case series.
A sample of nearly 8000 cases was collected, most presenting psoriasis vulgaris. This pathology, prevalent in males, first appears at an age somewhere between the teens and twenties. Numerous factors may be involved, and onset is mainly attributed to stress, viral or bacterial infections and pharmacological therapy. Over 90% of cases lost between 1 and 7 working days in the course of the year. Local anti-psoriasis treatment in monotherapy was administered more frequently than systemic therapy or combined therapy.
The results of this first Italian epidemiological study confirm that psoriasis is homogeneously distributed throughout the country. About 50% of patients avail themselves of specialist cures, even several times in the course of the year, and use a wide range of therapies which may be more or less demanding. The internal socio-economic cost of the disease is evident, particularly in terms of working days lost and/or medical expenses.
银屑病在全球范围内均有发生，其患病率在不同人群和不同地理区域有所差异。例如，北欧国家的发病率似乎高于南欧。然而，目前仍缺乏足够的数据进行国际层面的比较。
1994年，意大利银屑病研究跨学科协会（AISP）协调记录了在意大利各地均匀分布的皮肤科中心观察到的银屑病患者的月度病史和临床结果。结果是从整个病例系列中推断得出的。
收集了近8000例病例样本，大多数为寻常型银屑病。这种疾病在男性中更为普遍，首次出现的年龄在十几岁到二十几岁之间。可能涉及多种因素，发病主要归因于压力、病毒或细菌感染以及药物治疗。超过90%的病例在一年中损失了1至7个工作日。局部抗银屑病单一疗法的使用频率高于全身疗法或联合疗法。
这项首次意大利流行病学研究的结果证实，银屑病在全国分布均匀。约50%的患者接受专科治疗，甚至在一年中多次接受治疗，并使用了各种可能要求或多或少的疗法。该疾病的内部社会经济成本是明显的，特别是在工作日损失和/或医疗费用方面。
