Abstract
BACKGROUND: Psoriasis affects 0.2-0.7 % of children and is associated with obesity. Published studies have been conducted in hospital settings (tertiary care). The PsoLib study evaluated childhood psoriasis in private practice (secondary care) in terms of epidemiology, clinical aspects and comorbidities. PATIENTS AND METHODS: This was a non-interventional, cross-sectional, multicenter study of children with psoriasis performed by 41 dermatologists working in private practice. The clinical and therapeutic aspects and comorbidities were systemically evaluated. We compared data to the χ-Psocar study performed in hospitals using the same methodology. RESULTS: In all, 207 children (girls: 60.4 %; mean age: 10.5±4.2 years) were included. Scalp psoriasis (40.6 %) was the most frequent clinical type, while plaque psoriasis represented 26 % of cases. Nail, tongue, and arthritic involvement were rare. Less than 1 % of children suffered from hypertension, diabetes or dyslipidemia, but 16.4 % were overweight and 7.0 % were obese. Severity (PG≥4 at peak) was associated with excess weight (P=0.01). CONCLUSION: Scalp psoriasis is the most frequent clinical type of psoriasis in childhood. Comorbidities and extracutaneous localization are rare. Even in private practice, the severity of the disease is associated with excess weight.
