North American Pediatric Renal Transplant Cooperative Study (NAPRTCS) reports have shown anti-T cell antibody, OKT3, to be deleterious in pediatric renal transplant recipients treated with mycophenolate mofetil (MMF). Unlike OKT3, basiliximab is a chimeric monoclonal antibody to the alpha subunit of the interleukin-2 receptor on activated T-lymphocytes. We sought to examine the outcome of MMF with or without basiliximab induction therapy in pediatric renal transplantation. Between January 1998, and June 2001, 49 pediatric renal transplants were performed at our center and 41 met the criteria for this study. We retrospectively analyzed the records of 25 patients who received MMF, Prednisone, CSA or TAC, alone (group I) and 16 patients who received MMF, CSA or TAC, and Prednisone in combination with basiliximab (group II). The two groups were similar with respect to recipient or donor age, gender, ethnicity, donor source (LD vs. CAD), cold ischemia time, and primary diagnosis. The basiliximab group had a shorter follow up period because of its more recent addition to our pediatric immunosuppression protocol, 12.9 +/- 5.9 months vs. 35.5 +/- 7.2 months for group I (p < 0.0001). At 6 months, the acute rejection rate was 16% (group I) compared with 25% (group II) (p = 0.689). The patient and graft survival at 6 and 12 months were 100% respectively for both groups. Basiliximab was well tolerated without significant adverse events. At 6 months, there was no significant difference between the groups in the incidence of urinary tract infection or cytomegalovirus infection. These data suggest that in the short-term, MMF with or without basiliximab induction therapy appears to yield excellent and statistically similar outcomes. However, further controlled studies are necessary to verify these findings as well as to define the role of basiliximab in MMF-treated pediatric renal transplant recipients.

Steroid-free immunosuppression regimens have been enjoying recent success in clinical transplantation. The use of antibodies required for such protocols can be an economic burden. We proposed to study their cost in our center. This retrospective study involved 147 consecutive patients subjected to 4 protocols of immunosuppression. The first received triple therapy. The second group received induction with basiliximab, whereas the third received Basiliximab plus cyclosporine (CSA) plus mycophenolate mofetil (MMF), and the fourth received Thymoglobulin plus CSA plus MMF in conjuction with only 4 days of steroid. Rejection episodes were treated with Solumedrol. Six-month charges were obtained from computerized records of the finance department, the in-house laboratories, and the transplantation service registry. All charges were expressed in 2004 dollars. Statistical analyses were obtained using chi-square, analysis of variance (ANOVA) and Kaplan-Meier tests. The 4 groups were similar with regard to donor and/or recipient gender, race, panel reactive antibodies, cold ischemia, dialysis requirements length of stay and readmission, graft survival, and function. Charges were significantly higher in the last 2 groups as compared with triple therapy.

We studied prospectively the efficacy and safety of basiliximab combined with triple immunosuppression in adult recipients of > or = 1 HLA-mismatched deceased donor renal grafts. All studied patients received equal immunosuppressive drugs: 20 mg infusion of basiliximab on day 0 and on day 4, cyclosporine microemulsion (Neoral), mycophenolate mofetil, and methylprednisolone. An analysis of 1-year data assessed the incidence of acute rejection episodes, safety of this therapy, renal graft function, and patient and graft survivals. One hundred seventy-two patients were studied. The HLA-antigen mismatches were 2.9 +/- 0.9 (mean +/- SD), and the cold ischemia time was 22.0 +/- 7.5 hours. Fifty-three (31.5%) patients experienced delayed graft function. At 12 months, 5 (3.0%) patients experienced acute rejection. Six renal grafts were lost, but not from rejection. Two patients died. Sixty-six infections required treatment in the hospital. One carcinoma of cervix (in situ) and two basal cell carcinomas of skin were detected. Hypersensitivity reactions and cytokine-release syndrome were not observed. At 12 months, serum creatinine was significantly higher (119 +/- 46 micromol/L; P < .001) in patients with delayed graft function than in patients with immediate graft function (99 +/- 26 micromol/L). Patient and graft survivals were 98.8% and 97.1%, respectively. Basiliximab combined with this triple therapy was an efficient and safe immunosuppression strategy, demonstrated with very low incidence of acute rejections, an acceptable adverse event profile, excellent graft function, and high short-term survival rates in adult recipients of deceased donor renal transplant.

Low-risk renal transplant recipients treated with standard immunosuppressive therapy including interleukin-2 receptor (IL-2R) antagonist show a low incidence of early rejection episodes but few reports have examined the incidence and severity of late rejection processes. This study evaluated retrospectively cellular and antibody-mediated rejection (AMR) among 42 recipients selected because they showed low panel-reactive-antibodies, short cold ischemia time, no delayed graft function, and therapy including basiliximab (Simulect) induction. The mean observation time was 6.6 years. Sixty-seven percent of donors were deceased. Ten-year patient and death-censored graft survivals were 81% and 78%, respectively. Seven patients lost their kidneys due to nonimmunologic events. The seven recipients who experienced cellular rejection episodes during the first posttransplant year had them reversed with steroids. Five patients displayed late acute AMR causing functional deterioration in four cases including 1 graft loss. De novo sensitization occurred in 48% of recipients including patients without clinical rejection. In conclusion, long-term follow-up of kidney transplant recipients selected by a low immunologic risk showed a persistent risk of de novo sensitization evolving to acute AMR in 11% of cases. Although immunologic events were related to late immunosuppressive reduction, most graft losses were due to nonimmunologic factors.

Owing to the disparity between the supply of kidney donors and demand, the use of organs from older deceased donors was initiated in recent years. The potentially poor outcome of these grafts is a major concern. This retrospective study compares graft and patient 1-year survivals between recipients from expanded-criteria donors (ECD; n = 30) and standard-criteria donors (SCD; n = 104). Rates of delayed graft function (DGF), acute rejection (AR), and chronic injury in the pre-implantation biopsy were also assessed. Increasing donor age was associated with increased rates of DGF, and DGF correlated with AR. Cold ischemia time >30 hours was associated with worse graft outcomes. Induction with Simulect correlated with better patient survival compared with Timoglobulina. Chronic injury pre-implantation biopsy correlated with worse renal function, but graft survival was similar. Death-censored graft survival at 1 year was 90% and patient survival 82%, and these were similar in ECD and SCD recipients. Selection of transplant candidates for ECD kidneys must be performed with caution. One-year graft survival was similar to that of SCD kidneys, but kidney function was worse during the same period. This may result in poorer graft survival over longer follow-up.
