Background: Mycophenolate sodium (MPS) was designed to reduce the gastrointestinal side effects of mycophenolic acid. The aim of our study was to determine the safety and efficacy of MPS in de novo renal transplant recipients.
Patients and methods: This 6-month, multicenter, open-label, single-arm, prospective study was carried out in three centers in Poland. Thirty patients were recruited. Immunosuppressive regimen contained of MPS and cyclosporine (CsA) with or without steroids.
Results: The 6-month graft and patient survival was 100%. The incidence of suspected acute rejection episodes (ARE) was 5/30 (16.7%), including biopsy-proven ARE in 2 (6.7%) cases. ARE reversed after therapy. At month 6, the mean serum creatinine level was 1.4 mg/dL, and the mean creatinine clearance (according to the Cockroft-Gault formula) was >70 mL/min. The most frequent adverse effects included diarrhea, delayed graft function, anemia, and lymphocele. Among infections, most common were infections of urinary tract, cytomegalovirus infections, and infections of respiratory tract. Only three patients (10.0%) terminated the study prematurely, including two who discontinuated because of an adverse event, and one because of noncompliance.
Conclusions: An immunosuppressive regimen, including MPS and CsA, with or without steroids, provided effective antirejecton prophylaxis and was well tolerated.
