- m-TOR inhibitors (e.g. sirolimus) are well-tolerated immunosuppressants used in renal transplantation for prophylaxis of organ rejection, and are associated with long-term graft survival. Early use of sirolimus is often advocated by clinicians, but this may be associated with a number of side-effects including impaired wound-healing, lymphoceles and delayed graft function. As transplant clinicians with experience in the use of sirolimus, we believe such side-effects can be limited by tailored clinical management. We present recommendations based on published literature and our clinical experience. Furthermore, guidance is provided on sirolimus use during surgery, both at transplantation and for subsequent operations.

- BACKGROUND: Blood group ABO-incompatible live donor (LD) renal transplantation may provide a significant source of organs. We report the results of our first 14 cases of ABO-incompatible LD renal transplantation using specific anti-A/B antibody (Ab) immunoadsorption (IA) and anti-CD20 monoclonal Ab (mAb) treatment. PATIENTS AND TREATMENT PROTOCOL: Recipients were blood group O (n = 12), A (n = 1) and B (n = 1). Donors were A1 (n = 2), A2 (n = 3), A2B (n = 1) and B (n = 8), and all were secretor positive. Anti-human leukocyte antigen (HLA) Ab panel reactivity was negative in all recipients except one. All recipients were pre-treated with 3 to 6 IA sessions, using A or B carbohydrate antigen columns, until their anti-A1/B RBC panel indirect antiglobulin test (IAT) titers were < or =8. CDC crossmatch was negative in all cases. Recipients received preoperative mycophenolic acid, and steroids/tacrolimus were started at transplantation. No splenectomy was performed. Eight recipients received one dose of anti-CD20 mAb (rituximab, 375 mg/m2) pre-operatively and 11 recipients had postoperative protocol IA. RESULTS: In the initial protocol, anti-CD20 mAbs were used only for recipients receiving A1 grafts. One B graft (HLA-identical donor, 84% panel reactivity) was lost in a severe anti-B Ab-mediated acute rejection. Subsequently, the protocol included anti-CD20 for recipients of both A1 and B grafts and postoperative protocol IA to all recipients. The subsequent 10 grafts had excellent function, giving a total graft survival of 13/14 (observation range 2 to 41 months). At 1 yr, mean serum creatinine was 113 micromol/l (n = 8) and mean glomerular filtration rate was 55 ml/min/1.73 m2 (range 24 to 77). In the remaining five cases, with less than 1 yr follow up, mean serum creatinine was 145 micromol/l at 2 to 9 months follow up. Pre-IA anti-A/B titers were in the range of 2 to 32 (NaCl technique) and 16 to 512 (IAT). More than 90 IA sessions were performed in 14 recipients without any significant side effects. Recipient anti-A/B titers returned after transplantation to pre-IA levels or slightly lower. Postoperative renal biopsies were performed in 10 patients. In the 13 patients with long-term function, one patient experienced cellular rejection (Banff IIB) at 3 months without anti-B titer rise. This rejection was concomitant with low tacrolimus plasma levels and was easily reversed by steroids. In 8 of 10 cases, C4d staining was positive in peritubular capillaries. CONCLUSION: Blood group ABO-incompatible LD renal transplantation using A and B carbohydrate-specific IA and anti-CD20 mAbs has excellent graft survival and function.
