However, only three studies have been reported in which the paroxysmal-nocturnal-hemoglobinuria-like defect has been systematically sought in a series of patients with any form of myeloproliferative syndrome, and results have been variable. Of 50 patients with polycythemia vera, primary myelofibrosis and myeloid metaplasia, and the subtypes of acute myeloblasts leukemia reported by Catovsky and associates (4), none
