Abstract

The relationship between quality of life (QoL) and skin lesion improvement due to psoriasis treatment has been recently underlined. Our objective was to study the self-reported disease severity reduction and QoL during spa treatments and identify predictors of psoriasis improvement. Patients were assessed before and after spa treatment with a disease-specific QoL questionnaire (Skindex-17) and self-administered psoriasis area and severity index (SAPASI). Their correlations were tested. Factors predicting a reduction in Skindex-17 or in SAPASI score were evaluated through regression analysis. Significant mean overall reductions in SAPASI (27%) and Skindex-17 scores (psychosocial: 6%; symptoms: 2%) were achieved. However, 51% of patients reporting SAPASI improvement also reported a worsened QoL. Pearson's correlation between the SAPASI and Skindex-17 scores was poor (r=0.26 for SAPASI-symptoms and r=0.40 for SAPASI-psychosocial). Logistic regression analysis identified the age of psoriasis onset before 30 years (OR=3.81, 95% CI 1.22-11.95, p=0.02) and a basal Skindex-17 symptoms value greater than 5 (OR=3.37, 95% CI 1.12-10.08, p=0.03) as predictive of both SAPASI and Skindex-17 score reductions. Age-of-onset-based stratification identifies the subset most likely to respond to spa treatment. Combining the Skindex-17 with SAPASI provides a more comprehensive patient-centered assessment. We recommend this assessment for psoriasis patients undergoing spa treatment.
