Assessment of the efficacy, skin acceptability and cosmetic quality of an adjuvant cream based on 40% urea and amino-inositol in the treatment of mild psoriasis.

BACKGROUND: Psoriasis is a chronic inflammatory disease with a multifactorial genesis. Structural changes are encountered in psoriasis and skin barrier function is impaired. Tight junctions (TJs) play a key role in skin barrier dysfunction. Loss of profilaggrin or filaggrin leads to changes in the stratum corneum and consequent loss of water and the development of xerosis. METHODS: We carried out an observational study to evaluate the efficacy, skin acceptability and cosmetic qualities of a cream formulation, based on 40% urea and amino-inositol, in the treatment of mild psoriasis in the absence of other associated cosmetic/pharmacological treatments. All parameters were evaluated before (T0) and after 4 weeks (T4). Efficacy assessment was based on both clinical evaluation and photographic documentation. RESULTS: The results showed significant clinical improvement (-64.18% PASI, -57.11% BSA, -61.84% Plaque Score, -41.86% PGA and -76.34% VAS -77.5 DLQI) in 4 weeks of treatment. No significant side effects were reported. Similarly, the degree of satisfaction with the product and adherence to its use were particularly satisfactory among patients. CONCLUSIONS: The tested product was found to be a promising, effective adjuvant treatment in patients with mild psoriasis, and was also useful in reducing itchy symptoms, the impact on quality of life, as well as significantly reducing the clinical signs of psoriasis.
