AB We studied the changes in cellular immunity in patients in replacement
dialysis therapy (RDT) and examined the relationship between
T-lymphocyte function and plasma levels of parathyroid hormone (PTH). In
a preliminary study we found that increased plasma levels of PTH were
associated with a decrease of T-lymphocytes and CD4, an increase in CD8
and a reduction in the ratio of CD4 to CD8. In the present study we
examined the relationship between plasma levels of PTH, interleukin 2
receptors (IL-2R) and soluble human CD8 (S-CD8). We studied 54 patients
divided into two groups: 26 patients with normal levels of PTH and 28
patients with increased levels of PTH. We found a significant reduction
in total T-lymphocytes in both groups as compared to controls, with an
inverse correlation between total T-lymphocytes and plasma PTH in the
second group (R = -0.52). There was an increase in IL-2R in the group II
as compared to the controls and also in the total population of uremic
patients with a linear correlation between levels of IL-2R and PTH (R =
0.6). The levels of S-CD8 showed a significant increase in both groups
with a linear correlation between levels of SC-D8 and PTH (R = 0.63). No
specific differences were seen between patients treated with and without
1,25-dihydroxyvitamin D3. The elevated levels of PTH affect the
lymphocyte function and are associated with change in cellular immunity
with reduction in total number of T cells, and increases in levels of
CD8, S-CD8 and IL-2R.
