A long-term clinical trial of interferon alpha-therapy in essential thrombocythemia. Hydroxyurea has been proven to be an effective treatment for this condition. For over 50 years, HU has been used in the treatment of chronic myeloproliferative disorders, tromboxitoz as chronic myeloid leukemia, polycythemia vera, and ET [ 3 ].

Our patients were placed on HU since they had all suffered thrombotic events.


Tefferi A, Murphy S. We herein report 3 cases of HU-induced ulcers that were treated by discontinuation of HU and introduction of interferon, with marked improvement of the ulcers and good control of the ET. Its cytotoxic effects are most trombositooz in the bone marrow and in epithelial cells.
