Selective use of mycophenolate mofetil in renal transplant patients in Indian scenario.

Purpose: Although mycophenolate mofetil (MMF) has emerged as a valuable immunosuppressive in renal transplantation, its high cost demands that it be used selectively.

Materials And Methods: This retrospectively study included 55 renal transplant patients on MMF for rescue therapy after treatment of acute vascular rejection (n = 45), acute/chronic liver disease with elevated transaminases (n = 4), early chronic rejection (n = 2), cyclosporine toxicity (n = 3), and cyclosporine-induced hemolytic-uremic syndrome (n = 1). The patients were given 1.5 to 2 g MMF in divided doses for at least 6 months, depending upon the tolerability, adverse effects, and finances, and followed for 1 year. The patients on MMF following treatment of acute rejections were compared with controls who received azathioprine-based triple immunosuppression after treatment of an acute rejection episode.

Results: The incidence of recurrent acute rejection in the first year was 18% in the MMF group compared to 42% in the control group (P < .005). The serum transaminases in the acute/chronic liver disease group reached normal levels at 3 to 6 months. The serum creatinine remained stable for a mean duration of 8 months in the early chronic rejection patients. The patients with cyclosporine toxicity showed stable graft function on low-dose cyclosporine. The patient with hemolytic-uremic syndrome showed stable graft function for 4 years. The MMF-based triple regimen is two times more expensive than an azathioprine-based regimen.

Conclusion: MMF significantly decreases the recurrence of acute rejection. It is a good alternative agent in special situations like acute/chronic liver diseases with elevated transaminases, early chronic rejection, cyclosporine toxicity, and cyclosporine-induced hemolytic-uremic syndrome. Because of the high cost it should be used selectively in our population.
