Pruritus is defined as an unpleasant sensation of the skin that provoke the desire to scratch or rub. Its presence is an essential diagnostic feature. According to some European studies, 91% of patients with Atopic Dermatitis report suffering from pruritus at least once daily. And 58.1% of them experience chronic pruritus, leading to great deterioration in quality of life. Various internal and external factors may trigger pruritus. Mediators secretion such as keratinocyte-derived Thymic Stromal Lymphopoietin (TSLP) and Nerve Growth Factor (NGF) could activate nerve fibres which will eventually transmit signals to the brain causing the sensation of itching.
Although being one of the major annoying symptoms faced by patients with Atopic Dermatitis, effective anti-itching treatments are not available. There is no consistent evidence that topical antihistamines can relief itch.
Recently, a new spray named Atoderm 'SOS' is developed. The skin relief technology (by ambora extract and Epigallocatechin gallate (EGCG), associated to enoxolone) claimed to inhibit the release TSLP and NGF which eventually could reduce nerve signals to the brain for itchy feelings. Therefore, our group would like to test the efficacy of this proprietary anti-itch product with our paediatric patients using a wait-list approach as a control. It is aimed to demonstrate that the using the Atoderm 'SOS' spray topically whenever necessary can reduce the unpleasant itchy Atopic Dermatitis's symptom, improve quality of life, as well as to reduce the need for topical treatment.
