Twenty-two recipients of HLA-nonidentical living related and nonrelated
renal allografts were studied for alterations in the relative percentage
of OKT4-positive peripheral blood T-cells after transplantation. Characteristic
shifts in the ratio of T-helper to T -suppressor/cytotoxic cells (TH/TS-C),
but not absolute cell numbers, were demonstrated to correspond with the
status of the allograft. Our results are indicative of a correlation between
rejection episodes and the increase in OKT4:0KT8 ratios, that were
characterized by a significant rise in the percentage of OKT4-positive cells
(P=0.001), and a decrease in the percentage of OKT8-positive cells
(P=0.001).
