CD8A and kidney failure: The dialysis method had a significant impact on T cell recovery at T12 as patients on peritoneal dialysis (PD) had increased counts of T cells [2500 (1798–3100) vs. 1600 (1300–2126) cells/μL, p = 0.005], CD8+ T cells [675 (589–987) vs. 471 (375–678) cells/μL, p = 0.01] and NKs [219 (198–467) vs. 148 (101–291) cells/μL, p = 0.01] in comparison with hemodialysis (HD) patients.
