AIM: To develop an experimental model of islet allotransplantation in
diabetic rats and to determine the positive or adverse effects of MMF as
a single agent.
METHODS: Thirty-six male Wistar rats and 18 male Lewis rats were used as
recipients and donors respectively. Diabetes was induced by the use of
streptozotocin (60 mg/kg) intraperitoneally. Unpurified islets were
isolated using the collagenase digestion technique and transplanted into
the splenic parenchyma. The recipients were randomly assigned to one of
the following three groups: group A (control group) had no
immunosuppression; group B received cyclosporine (CsA) (5 mg/kg); group
C received mycophenolate mofetil (MMF) (20 mg/kg). The animals were
killed on the 12(th) d. Blood and grafted tissues were obtained for
laboratory and histological assessment.
RESULTS: Median allograft survival was significantly higher in the two
therapy groups than that in the controls (10 and 12 d for CsA and MMF
respectively vs 0 d for the control group, P<0.01). No difference in
allograft survival between the CsA and MMF groups was found. However,
MMF had less renal and hepatic toxicity and allowed weight gain.
CONCLUSION: Monotherapy with MMF for immunosuppression was safe in an
experimental model of islet allotransplantation and was equally
effective with cyclosporine, with less toxicity. (C) 2005 The WJG Press
