ABSTRACT
Objectives: Early conversion from CNI to MMF/SRL regimen
has shown benefits in graft function and patient/graft
survival with low rejection rate in kidney transplantation.
We evaluated the early conversion impact of MMF/SRL in
patients withdrawn from CNI.
Material and Methods:
We prospectively followed 32 patients converted from CNI
to SRL before 12 months following transplantation during
25 months. Patients underwent abrupt CNI cessation with
SRL introduction and adjustment to maintain 5-10 ng/mL
levels. MMF decreased to 1-1.5 gr/day.
Results: 19 patients
(59.4%) were male. Mean age was 29.6 ± 9.8 years. Most
grafts were living donors (n=26, 81.3%). Mean donor age
was 41.7 ± 9.5 years. Mean SRL conversion time was 6.1 ±
2.8 months. Postconversion acute rejection rate was 6.25%.
All patients has been followed for 9 months. Patient/graft
survival was 96 & 90%. BUN decreased throughout the
study (p‹0.05), SCr improved (p‹0.005) up to 12 months
of follow-up. Mean estimated GFR increased (p‹0.005) up
to 18 months of follow-up. 24 hour urine protein excretion
was increased (p‹0.05) 3 months after conversion. Withdrawal
rate was 12.5%.
Conclusions: Early conversion
from CNI to SRL in low to moderate risk patients, is safe,
well tolerated and associated with a significantly increase
in estimated GFR following SRL introduction.
