Idiopathic CD4+ T-Lymphocytopenia -- Four Patients with Opportunistic Infections and No Evidence of HIV Infection

Abstract

These four patients had idiopathic CD4+ T-lymphocytopenia with opportunistic infections but no evidence of HIV infection. Instead of the progressive, selective depletion of CD4+ T cells characteristic of HIV infection, some patients with idiopathic immunodeficiency have stable CD4+ cell counts accompanied by reductions in the levels of several other lymphocyte subgroups.
