The aim of this study was to define the prevalence and clinical features of Juvenile Psoriatic Arthritis (JPsA). According to the definition by Ansell and Bywaters, we identified the population at risk of JPsA in 425 patients with psoriasis with onset occurring before the age of 31. Among these, 85 were younger than 16 years. Five patients with JPsA were found (prevalence 1.0%). All had a family history of psoriasis and onset of skin disease in the age range 10 to 20 years. Arthritis preceded psoriasis in two cases, while in the remainder the converse occurred. The interval between the onset of cutaneous and articular involvement never exceeded 8 years. Previous studies reported the low frequency of JPsA among juvenile arthritides. Our data appear to underline the rarity of the arthritic form.
本研究的目的是确定青少年银屑病关节炎（JPsA）的患病率和临床特征。根据安塞尔和拜沃特斯的定义，我们在425例31岁之前发病的银屑病患者中确定了JPsA的高危人群。其中，85例年龄小于16岁。发现5例JPsA患者（患病率1.0%）。所有患者均有银屑病家族史，皮肤病发病年龄在10至20岁之间。2例关节炎先于银屑病出现，其余病例则相反。皮肤和关节受累发作之间的间隔从未超过8年。既往研究报道JPsA在青少年关节炎中发病率较低。我们的数据似乎凸显了关节炎形式的罕见性。
