A recent study published in the journal ofEgyptian Rheumatology and Rehabilitationrevealed that children with psoriasis are at greater risk of developing juvenile psoriatic arthritis (JPsA) if they have elevated body mass index (BMI) or nail psoriasis. These factors may serve as important clinical indicators for early screening and intervention in at-risk pediatric patients. Of the 7 types of juvenile idiopathic arthritis (JIA), juvenile psoriatic arthritis (JPsA) affects around 1–7% of the total JIA population. One of the main criteria for diagnosing JPsA is the correlation between psoriasis and arthritis. Even in youngsters, PsA is a progressive condition that causes joint deterioration and bone erosion. Better results might arise from early detection of PsA. Clinical risk factors for the development of PsA in adults include the severity of psoriasis, obesity, uveitis, hypercholesterolemia, smoking, trauma, and depression. These stimuli might set off a chain reaction of inflammation that eventually results in dactylitis, enthesitis, and arthritis. However, the risk factors for JPsA development in children with psoriasis are poorly understood. Therefore, this study was set to look at many clinical risk factors for children with psoriasis to develop psoriatic arthritis. In addition to 40 children with JPsA (group II), 40 children with psoriasis without arthritis (group I) were included in this study. Every patient had a complete medical history, a clinical examination, a laboratory evaluation, a body mass index (BMI) calculation, and a PASI score to determine the severity of their psoriasis. There was no discernible difference between the two groups in terms of psoriasis family history, age, or sex. When compared to 2.5% and 15% in group I, 47.5% and 32.5% of group II were overweight and obese, respectively. Group II had a non-significantly greater percentage of passive smoking (37.5%) than group I (25%). ESR and CRP values were substantially higher in Group II of the patients under study (P < 0.001). Group I developed nail psoriasis at a rate of 22.5%, whereas group II had it at 65 percent (P<0.001). Overweight, obesity, and nail psoriasis were predictors of developing JPsA using binary logistic regression (P<0.05 and OR >1 with 95% CI). Overall, this evidence suggests that in order to forecast JPsA, it is necessary to monitor children with psoriasis, particularly those who are overweight and have nail psoriasis. Abdella, D. H.
