Several protocols allow the successful ABO incompatible living-related kidney transplantation (ABO-ILKTWe compared the patient and graft survival rates as well as the incidence rate of acute rejection in these two eras, when different regimens were used. There were significant differences in the 1-and 5-year graft survival rates between groups 1 and 2 (1-year: 78% in group 1 vs. 94% in group 2; 5-year: 73% in group 1 vs. 90% in group 2, p = 0.008). Also, a higher incidence rate of acute rejection was significantly observed in group 1 (50/105, 48%) than in group 2 (18/117, 15%) (p < 0.001). We conclude that the FK/MMF combination regimen provides excellent graft survival results in ABO-ILKT.

PP appears to be effective for the prevention and treatment of posttransplant recurrence of FSGS, although further consideration of cost/benefit and risks is required before a conclusive judgement can be made.

In this study, we examined the impact of preoperative anti-A/B antibody titers on the results of ABO-incompatible living kidney transplantation (LKT). In all, 167 recipients underwent ABO-incompatible LKT at our institution between 1989 and 2002. These patients were subdivided into those transplanted under cyclosporine with azathioprine or mizoribine (Group 1, n=78) and those transplanted under tacrolimus or mycophenolate mofetil (Group 2, n=89). Overall patient survival at 5 and 10 years was 93.8% and 88.0%, respectively. Overall graft survival at 5 and 10 years was 76.9% and 55.9%, respectively. Graft survival in the patients with anti-A/B IgG titers over 1:128 was significantly lower in group 1, whereas no significant correlation between the anti-A/B IgG titers and graft survival was found in group 2. In conclusion, no correlation between anti-A/B antibody titers and the results of ABO-incompatible LKT was seen after tacrolimus or mycophenolate mofetil application.

Patient survival was 93% at 1 year and 91% at 8 years. Graft survival was 79% at 1, 2, 3, and 4 years, 75% at 5 and 6 years, and 73% at 7 and 8 years. Patient survival was not significantly different from that of ABO-compatible patients. However, graft survival was significantly different between ABO-incompatible grafts and ABO-compatible grafts. Specifically, ABO-incompatible transplant recipients experienced a significantly higher rate of early graft loss up to 3 years but showed an equivalent graft loss by year 4. Among 67 patients, 16 grafts were lost during the observation period. Loss was due to acute rejection in 5 patients, followed by chronic rejection in 5 patients and death with function in 3 patients, whereas immunosuppression was withdrawn in 3 patients due to nonimmunological reasons. Of 16 grafts lost, 15 were lost within 1 year after transplantation. Of the 67 patients, 5 died during observation. Three patients with functioning grafts died of uncontrolled bleeding due to duodenal ulcer, malignant lymphoma, and cerebral hemorrhage (one patient each). One patient died of ischemic colitis due to secondary amyloidosis and one patient of cerebral hemorrhage after graft loss due to humoral rejection. There was no fatal infectious complication, whereas 10 patients had non-tissue-invasive cytomegalovirus infection. The stepwise logistic regression model was employed to identify the most important factors for long-term renal function. Patients were subdivided into those with serum creatinine of less than 2.0 mg/dl (group 1, n=39) versus those with serum creatinine of more than 2.0 mg/dl (group 2, n=22) at one year after renal transplantation. Six patients were excluded because of death with functioning graft (three patients) and withdrawal of immunosuppression (three patients). Rejection episodes within 6 months were significantly frequent in group 2 compared with group 1 (P=0.0008). Odds ratio was 112-fold in the rejection episodes. Obviously, the high incidence of early humoral rejection is caused by ABO incompatibility, because ABO-incompatible grafts experience a higher rate of early rejection and graft loss compa

The reaction products of F-propene and dialkylamines, mixtures of α,α-difluoroalkylamine and α-fluoro enamine, were found to be useful fluorinating agents for alcohols and carboxylic acids. These reagents were superior to the adduct of chlorotrifluoroethene and diethylamine, the so-called Yarovenko reagent, for their readier preparation and higher stability.
