The hypereosinophilic syndrome comprises various idiopathicmyeloproliferative disorders with sustained eosinophilia anddamage to the heart, lungs, skin, and other organs by infiltratingeosinophils.1 A single mechanism for this syndrome has not beenidentified, and multiple factors are likely to be involved.The serum level of interleukin-5, an eosinophilopoietic cytokine,is increased in some patients with the hypereosinophilic syndrome,2and a few have been found to have unusual T-cell abnormalities,including CD3CD4+CD8 T cells3,4 and so-calleddouble-negative CD3+CD4CD8 T cells.5 CD3, a complexof five proteins associated with the T-cell receptor, is a distinctivefeature of all normal T cells. . . .
