ABSTRACT
BACKGROUND:
Although enteric-coated mycophenolate sodium (EC-MPS) was developed to reduce gastrointestinal (GI) side effects in kidney transplantation, a multicenter clinical trial of patients undergoing de novo renal transplantation found that efficacy failure and adverse GI event rates for EC-MPS were comparable with mycophenolate mofetil (MMF). A common strategy to mitigate mycophenolic acid-related GI adverse events includes dose manipulations such as split dosing, dose reduction, and discontinuation. Several studies have demonstrated that dose alterations with MMF are associated with poorer graft outcomes.METHODS:
To determine whether there was a clinically significant difference in dose alterations and outcomes with EC-MPS compared with MMF, we conducted a retrospective study comparing MMF and EC-MPS in all consecutive kidney transplants (n=1709) between 2000 and 2006.RESULTS:
Graft survival between MMF and EC-MPS patients was not different during the study period (P=0.9928). The incidence of biopsy-proven acute rejection at 2 years was higher in the MMF group (30.2% MMF vs. 21.9% EC-MPS, P=0.0004). The adjusted risk of dose reductions was significantly higher in MMF-treated patients (hazard ratio=1.703, P<0.0001). Similarly, the adjusted risk of drug discontinuation was higher in the MMF group (hazard ratio=1.507, P=0.0002). EC-MPS patients also demonstrated a trend toward a lower incidence of infections and a significantly lower incidence of fungal infections.CONCLUSION:
EC-MPS was associated with fewer dose reductions or discontinuations, which may have translated into the observed significantly lower incidence of biopsy-proven rejection. EC-MPS has become the mycophenolic acid agent of choice at this large center.
