Objectives: Our goal was to determine whether mycophenolic acid (MPA) modulates peripheral blood lymphocyte T in kidney transplant recipients. Patients and Methods: We assessed T lymphocytes CD3, CD4 and CD8 in peripheral blood in 30 donors and 35 recipients one day before and 10 days after transplantation using Becton Dickinson’s direct immune fluorescent light. Results: Comparisons showed that the number of T lymphocytes CD3+, CD4+, CD8+ in peripheral blood of transplant recipients were lower than donors (TCD3 was 1690.31±503.45 versus 2280.73± 522.48; TCD4 was 549.51 ±211.72 cell/µL versus 766.37± 341.72 cell/µL and CD8 was 1134.37 ±431.07 cell/µL versus 1523.4± 349.23 cell/µL with P<0.001; P=0.001 and P= 0.0002 respectively). Additionally, post-transplantation lymphocytes TCD4 decreased in 10/35 of recipients and increased in 22/35 of recipients (P=0.036). Conclusion: The T lymphocytes CD3, CD4 and CD8 in peripheral blood should be monitored at multiple post-transplant times to make early predictions of transplant rejection during follow-up treatment.
