Overview

BackgroundDiagnosis and treatment of psoriatic arthritis require attention from specialists. Clinical manifestations of psoriatic arthritis in children are variable.ObjectivesThe purpose of the study: to evaluate the clinical picture of psoriatic arthritis (PsA) in children.MethodsThe case histories of 23 children with psoriatic arthritis aged 3 to 17 years who were treated by a rheumatologist from 2019 to 2022 were analyzed.ResultsProbable psoriatic arthritis was diagnosed in 7 (29%) patients, definite psoriatic arthritis was diagnosed in 16 (71%) patients. At the same time, 12 (53%) children fell ill at the age of up to 7.5 years. In 7 (29%) patients, the disease began with skin lesions, in 16 (71%) patients immediately with articular syndrome. In the group of patients with certain psoriasis, plaque psoriasis was noted, it was detected in 17 (76.3%) children, guttate psoriasis was in 3 (13.5%), isolated psoriasis of the nails in 3 (10.2%) children. In 5 (21.7%) children, lesions of the skin and nail plates were observed. It was noted that psoriatic onychodystrophy was represented by onycholysis, an “oil spot” in the area of fingers and toes in 5 (23%) patients, and thimble symptom was diagnosed in 4 (18.1%) patients. At the onset of the disease, oligoarticular or asymmetric articular syndrome was noted in 65.6% of cases, a symmetrical rheumatoid-like variant in 20.2% of cases, and psoriatic spondylitis in 14.2% of cases. The dynamics of the articular syndrome after 3 years of observation and treatment indicated the development of symmetrical rheumatoid-like arthritis in 41.2% of patients, asymmetric oligoarthritis in 24.1% of children, and spondyloarthritis in 22.1%.ConclusionThe clinical picture of psoriatic arthritis in children is variable. Skin lesions preceded the development of arthritis in children. At the onset of the disease, asymmetric oligoarthritis predominated, followed by transformation into symmetrical rheumatoid-like arthritis.REFERENCES:NIL.Acknowledgements:NIL.Disclosure of InterestsNone Declared.
