Quality of life in renal transplant recipients following conversion from mycophenolate mofetil to enteric-coated mycophenolate sodium.
BACKGROUND
Tolerance to immunosuppresant treatment has considerable impact on adherence to therapy and on the outcome of renal transplantation. Recent data indicate better gastrointestinal tolerance to enteric-coated mycophenolate sodium (EC-MPS) than to the classic mycophenolate mofetil (MMF) formulation.


OBJECTIVE
This study assessed the effect of conversion therapy from MMF to EC-MPS on gastrointestinal tolerance and quality of life in renal transplant recipients.


METHODS
This open observational study analyzed the outcomes of conversion from MMF to EC-MPS among renal transplant patients with gastrointestinal complaints. At baseline (B) and at 8 weeks postconversion patients were assessed by the Gastrointestinal Quality of Life Index (GIQLI) questionnaire as well as by clinical evaluation (acute rejection, infection) and analytical determinations.


RESULTS
We analyzed 18 recipients of cadaveric renal transplants of mean age of 54 +/- 9 years including 61% men and one retransplant. Our patients had stable renal function with mean creatinine of 1.9 +/- 0.7 mg/dL. Baseline treatment included cyclosporine-MMF-prednisone (33%) or FK-MMF-prednisone (66%). Bioequivalent conversion was carried out at 50 +/- 29 months posttransplantation. Conversion to EC-MPS resulted in an improvement in overall quality of life (total score: baseline 106.61 vs 8 weeks 116.89; P < .01). Improvements were observed in the following GIQLI subscales: gastrointestinal symptoms (3.12 vs 3.48, P < .001), physical function (2.54 vs 2.76, P = .003), medical treatment (2.17 vs 2.50, P = .031), and emotion (3.08 vs 3.39, P = .001). No changes were observed in the social function subscale. The hemogram and renal function remained stable; there were no episodes of rejection or infection.


CONCLUSIONS
Conversion from MMF to an EC-MPS formulation was associated with improvements in gastrointestinal complaints and quality of life among renal transplant recipients.
