Patients in the MMF group were administered tablet mycophenolate mofetil at a starting dose of 500 mg twice daily if the weight of the patient was less than 50 kilograms and 750 mg twice daily if the weight was more than 50 kilograms. After one month, the dose of MMF was increased to 750 mg twice daily. The clinical response was monitored in terms of reduction in serum creatinine and proteinuria. MMF dose was decreased or interrupted in patients experiencing an absolute neutrophil count <1300/mm3 at any study visit; MMF treatment was discontinued if a patient experienced an absolute neutrophil count <1000/mm3.
