Background. Statin therapy has been reported to reduce the acute rejection
rate following renal transplantation in a pilot study. The present study is
the first randomized, double-blind and adequately powered study to examine
the effect of statins on acute rejection of renal allografts.
Methods. A total of 364 patients were randomly assigned to receive either f
luvastatin 40 mg or placebo in combination with conventional cyclosporine-b
ased immunosuppressive therapy. The primary end point was treated first acu
te rejection. Secondary end points included biopsy-proven rejection, histol
ogical severity of rejection, occurrence of steroid-resistant rejection, an
d serum creatinine at three months following transplantation.
Results. Fluvastatin was well tolerated; no patients developed myositis or
rhabdomyolysis. There was no difference in the acute rejection rate [86 (47
.3%) fluvastatin vs. 87 (47.8%) placebo] and no significant difference in t
he severity of rejection, steroid resistant rejection or mean serum creatin
ine at three months (160 mu mol/L vs. 160 mu mol/L). Total cholesterol, low
-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol a
nd triglyceride levels increased following renal transplantation. With the
exception of the increase in HDL-C, which was augmented, the increases in l
ipid parameters were significantly reduced by fluvastatin (total cholestero
l +17.5% vs. 35.7%; LDL-C +6.3% vs. 46.7%; HDL-C +43.3% vs. 38.1%; triglyce
ride +52.2% vs 77.6%).
Conclusions. Contrary to the reported effects of statins, fluvastatin had n
o effect on the incidence or severity of acute rejection following renal tr
ansplantation. There were no increases in adverse events. A significant and
potentially beneficial alteration in the lipid profile was observed in the
early post transplant period. We conclude that fluvastatin may be used saf
ely to correct dyslipidemia in patients with end-stage renal failure throug
h the peri-transplant period.
