Aprepitant Versus Hydroxyzine in Association With Cytoreductive Treatments for Patients With Myeloproliferative Neoplasia Suffering From Persistent Aquagenic Pruritus.

Phase 3, randomized prospective study, double blind-double placebo, testing oral therapies APREPITANT versus HYDROXYZINE in patients followed for myeloproliferative neoplasms and suffering of persistent aquagenic pruritus.

Identification of patients with myeloproliferative neoplasms and aquagenic pruritus. Evaluation of the intensity of the aquagenic pruritus. Patients with value >5/10 on the VAS (Visual Analogue Scale ) are proposed to participate to the protocole. Randomization between the two treatments. Duration of the treatment : 14 days. Regular evaluation of efficacity of the drugs (questionnaires). Evaluations will stop 2 months after the last intake. Blood samples will be collected before and after the intakes to study cytokine and neuropeptide levels.
