Abstract: 【Abstract】 Objective To investigate clinical characteristics of pediatric psoriasis based on the information systems from two children′s hospitals. Methods Clinical data on outpatients confirmly diagnosed with pediatric psoriasis were collected from information systems of Beijing Children′s Hospital affiliated to Capital Medical University and Children′s Hospital of Chongqing Medical University from January 1, 2015 to December 31, 2019, and a clinical and epidemiological investigation was conducted. Statistical analysis was carried out by using t test and chi-square test. Results A total of 5 235 children with psoriasis were included, with the ratio of male to female being 1∶1.08. Their age at the clinic visit (M [Q1, Q3]) was 8.37 (6.48, 10.50) years, and the school-age children were the most common population; their age at onset was 7.57 (5.37, 9.82) years. Among the 5 235 children with psoriasis, there were 3 195 (60.82%) with psoriasis vulgaris, 281 (5.37%) with pustular psoriasis, 19 (0.36%) with erythrodermic psoriasis, and 1 (0.02%) with psoriatic arthritis. The trunk (87.76%, 1 097/1 250) was most frequently affected, followed by the limbs (87.68%, 1 096/1 250), the scalp (62.56%, 782/1 250), and the face and neck (35.76%, 477/1 250). Among the 5 235 patients, 4 319(82.50%) received topical treatments, 177 (3.38%) received systemic treatments, and 832 (15.89%) were treated with antibiotics. Among 3 497 children who received initial treatment regimens, the disease could be controlled in 3 423 (97.88%) without change in treatment regimens, while treatment regimens needed to be adjusted in 2.12%. Conclusions In the two children′s hospitals, most children with psoriasis developed this condition and visited the clinic at school age, and the predominant clinical type was psoriasis vulgaris. Most skin lesions were extensive, and commonly occurred on the trunk and limbs. Scalp involvement was not uncommon. The condition could be controlled by topical treatments in most children with psoriasis, while a few patients needed systemic treatments.
