Methods: T-lymphocyte subtypes of the peripheral blood and cutaneous delayed-typ e hypersensitivity (DTH) response to two recall antigens, tetanus toxoid (TT) an d purified protein derivative(PPD), were measured in five patients with HIE and 15 healthy controls, respectively. Results: The CD4+ cell cou nts in HIE group were significantly lower than those in control group (P<0. 01). In contrast, CD8+ cells were significantly higher than those in the contro l (P<0.01). The induration sizes of DTH response to two recall antigens wer e smaller in HIE group than those in the control group (P<0.01).
