Official Title: Evaluation of the Antipruritic Effect of Elidel (Pimecrolimus) in Non-atopic Pruritic Disease
Brief Summary:
The development of the topical calcineurin inhibitor pimecrolimus resulted in a significant improvement in the treatment of atopic dermatitis. In addition, an excellent amelioration of pruritus could be regularly observed. Up to now, several itchy dermatoses such as chronic irritative hand dermatitis, rosacea, graft-versus-host-disease, lichen sclerosus, prurigo simplex, scrotal eczema, and inverse psoriasis were reported as single cases also to respond to a pimecrolimus treatment.
In prurigo nodularis, pruritus is the main symptom and it is of immediate importance to find an effective antipruritic therapy. Pruritus is regularly severe and therapy refractory to topical steroids or systemic antihistamines. Capsaicin cream is one effective possibility to reduce the itch in these diseases. However, it has to be applied 3 to 6 times daily, rubs off on the clothing and induces burning in erosions. In addition, since no commercial preparation is available, it has to be prescribed in several concentrations. The application of pimecrolimus seems to be promising since it has to be applied twice daily only. Especially in prurigo nodularis we expect a good response as we could demonstrate in single patients. Furthermore it has been published recently that Tacrolimus, another calcineurin inhibitor has been successfully used in the treatment of six patients with prurigo nodularis.
This study is designed to compare the efficacy and safety of pimecrolimus 1% cream and hydrocortisone 1% cream in prurigo nodularis and to investigate the mode of action of the antipruritic effect of the drugs.
