T gamma cell deficiency in idiopathic thrombocytopenic purpura (ITP).

Abstract
A significant reduction in the proportion and absolute number of circulating T gamma (suppressor) lymphocytes was observed in 15 adult patients with idiopathic thrombocytopenic purpura (ITP). The proportion of T gamma cells was also reduced in the spleen of four patients so investigated. This abnormality was not seen in 5 patients cured by splenectomy whilst it persisted in 3 who remained thrombocytopenic after splenectomy. The proportion of Tmu (helper) lymphocytes in ITP was normal. These findings, similar to those reported in systemic lupus erythematosus, suggest that an inbalance of the immunoregulatory T-cell subsets may be important in the pathogenesis of ITP.
