Comparison of enteric-coated mycophenolate sodium with mycophenolate mofetil in living renal allograft transplantation

OBJECTIVE: Enteric-coated mycophenolate sodium (MPS) has been developed to decrease the GI side effects of mycophenolate mofetil (MMF). We did a retrospective analysis of 112 patients to compare the safety and efficacy of enteric coated MPS vs MMF in living renal transplantation. METHODS: Patients were divided into two groups. Group A who received MPS [Novartis, Basel, Switzerland] [1.08-1.44 g/d] included 53 patients of mean age 33.5 +/- 11.9 yrs, and M:F gender ratio 37:15 with a mean donor age of 43.2 +/- 9.9 years. Group B who received MMF [1.5-2.0 g/d] included 59 subjects of mean age 33.2 +/- 9.9 yrs and M:F gender ratio 57:6, with a mean donor age of 41.4 +/- 10.9 years. All patients received cyclosporine and prednisolone in addition to mycophenolate. Mean follow-up in the two groups was 11.6 +/- 7.0 and 12.6 +/- 8.5 months, respectively. RESULTS: There were 11 (20.7%) rejection episodes in Group A and 12 (20.3%) rejection episodes in Group B (P = NS). Incidence of CMV disease was 9.61% and 10.1%, and of other infections, 88.7% and 74.7% in Groups A and Group B, respectively [P = NS]. The incidence of GI (18.9% & 20.3%) and hematologic toxicities (9.4% & 5.1%) were similar in the groups. Patient and graft survivals in Group A were 91.9% & 86.6%, and in Group B was 91.3% & 91.3%, respectively [P = NS]. CONCLUSION: Mycophenolate sodium is an alternative immunosuppressant to mycophenolate mofetil in kidney transplant recipients with a similar efficacy and safety profile.
