Introduction. Both atorvastatin and mycophenolate mofetil (MMF) have been used for panel reactive antibodies (PRA) reduction in transplant candidates. The purpose of this study was to compare the effect of low-dose MMF and atorvastatin on PRA in sensitized hemodialysis patients waiting for kidney transplantation.

Materials and Methods. A total of 40 adult patients with end-stage renal diseaseĀ  who were highly sensitized to human leukocyte antigens (PRA > 40%) were enrolled and randomly assigned into atorvastatin or low-dose MMF groups. All of the patients received the treatments for 2 months. The PRA status was determined at the end of the 1st and 2nd month.

Results. Forty percent of the patients in the atorvastatin group compared with 5% in the low-dose MMF group showed complete response, defined as a minimum 50% reduction in PRA (P = .02). Reduction of PRA in the atorvastatin group was significantly higher than that in the low-dose MMF group (P = .01). No major infectious or other complications occurred in our patients.

Conclusions. Atorvastatin has a significant effect on lowering of PRA in sensitized hemodialysis patients waiting for kidney transplantation. In addition, a short course of low-dose MMF is safe in ESRD patients; however, it has no effect on reduction of PRA.
