All Itching Is Not Benign; A Case of Refractory Hypereosinophilic Syndrome Treated with Off Label CD52 Inhibitor-Alemtuzumab

CONCLUSIONOur patient responded well to alemtuzumab, without any notable side effects. Therapy should be reserved due to early and late adverse affects but this agent has proved to be an effective treatment for HES in terms of both complete hematologic response and duration (Strati, P. et. al Clinical Lymphoma, Myeloma & Leukemia 2012). Moreover resistance is not seen, as patients with relapse were able to achieve a second remission. Data about efficacy and safety in the long-term remains lacking, but for treatment resistant and refractory HES, Alemtuzmab may be a suitable choice.DisclosuresNo relevant conflicts of interest to declare.
