Acute rejection after renal transplantation is reduced by approximately 50% by prior therapeutic blood transfusions, even in tacrolimus-treated patients.

BACKGROUND: The authors investigated the relationship between therapeutic blood transfusion before renal transplantation and rejection rates in cyclosporine- and tacrolimus-treated patients. METHODS: In one center, 265 consecutive recipients were studied. Protocol induction was with azathioprine, prednisolone, and cyclosporine or tacrolimus; 37% had biopsy-proven acute rejection in the first 6 months and 46% had received zero to two units of blood before transplantation. RESULTS: Lower risk of rejection was associated with tacrolimus induction (odds ratio [OR], 0.53; 95% confidence interval [CI], 0.29-0.95; P=0.049), prior transfusion of three or more units of blood (OR, 0.54; 95% CI, 0.33-0.90; P=0.024), and older age at transplantation (mean, 44.23 +/- 12.56 [+/- SD] years vs. 38.96 +/- 12.37 years; P=0.001). Multiple logistic regression modeling showed the effect of three or more prior transfusions on acute rejection was as follows: OR, 0.49; 95% CI, 0.29 to 0.83; P=0.008. CONCLUSIONS: Induction immunosuppression should take account of the higher risk of rejection in patients coming to transplantation who have previously received zero to two units of blood.

A randomized, double-blind trial of basiliximab immunoprophylaxis plus triple therapy in kidney transplant recipients.

BACKGROUND: A double-blind, placebo-controlled, randomized study was performed to assess whether immunoprophylaxis with basiliximab (Simulect) could reduce the incidence of acute rejection in kidney transplant recipients treated with cyclosporine (Neoral), steroids, and azathioprine. METHODS: Three hundred forty patients received either placebo or basiliximab at a dose of 20 mg, given intravenously on days 0 and 4. All patients received cyclosporine, steroids, and azathioprine. The primary endpoint was the incidence of acute rejection at 6 months. Secondary endpoints included the safety and tolerability of basiliximab and placebo, 1-year patient and graft survival, and significant medical events up to 12 months. RESULTS: During the first 6 months posttransplantation, acute rejection occurred in 20.8% of patients given basiliximab versus 34.9% of patients administered placebo (P=0.005). Similarly, there was a reduction in biopsy-proven acute rejection at 6 months in the patients receiving basiliximab (P=0.023). One-year patient survival was 97.6% with basiliximab and 97.1% with placebo, graft survival was 91.5% versus 88.4%, respectively (NS). The adverse-events profile of patients treated with basiliximab was indistinguishable from that of patients treated with placebo. The number of patients with infections was similar (65.5% for basiliximab vs. 65.7% for placebo), including cytomegalovirus infections (17.3% vs. 14.5%, P=0.245). Nine neoplasms (three in the basiliximab group, six in the placebo arm) were recorded up to 1 year from transplantation. CONCLUSIONS: Basiliximab in combination with cyclosporine, steroids, and azathioprine triple therapy was highly effective in reducing the incidence of acute renal allograft rejection without increasing the incidence of infections and other side effects.

Conversion from tacrolimus to cyclosporin in stable renal transplant patients: safety, metabolic changes, and pharmacokinetic comparison.

BACKGROUND: Conversion from tacrolimus to cyclosporin has not previously been reported as routine clinical practice, but only as indicated by rejection or adverse effects. METHODS: The safety and metabolic outcome of elective conversion from tacrolimus to cyclosporin was examined in 19 recipients of cadaver renal transplants. Conversion was performed in stable patients at 3-6 months after transplantation. RESULTS: Patient and graft survival was 100% at 3 months after conversion, with no rejection episodes. Three patients have been subsequently converted back to tacrolimus, two for rejection and one for hirsutism. There were no significant changes in creatinine, urate, or blood sugar levels after conversion, but the mean plasma magnesium rose from 0.73 (0.63-0.97) to 0.82 (0.65-1) mmol/liter (P=0.037), and the mean plasma cholesterol rose from 5.2 (3.4-6.8) to 5.5 (3.8-7.6) mmol/liter (P=0.033). Pharmacokinetic profiles were measured before and after conversion, and showed that cyclosporin (Neoral) exhibited significantly less interpatient and intrapatient variability than tacrolimus, for area under the curve (AUC), maximum concentration postdose (Cmax), minimum concentration postdose (Cmin), time to maximum concentration (Tmax). CONCLUSION: This is the first study that has examined the outcome of conversion from tacrolimus- to cyclosporin-based immunosuppression in stable patients after renal transplantation. This conversion was performed without early immunological hazard, but there was a small rise in blood cholesterol levels after conversion. Pharmacokinetic studies showed cyclosporin in the form of Neoral showed less inter- and intrapatient variability than tacrolimus, although this is of uncertain clinical significance.

Conversion from tacrolimus to cyclosporine in stable renal transplant patients: safety, metabolic changes, and pharmacokinetic comparison.

BACKGROUND: Although conversion between tacrolimus and cyclosporine has been performed when indicated for rejection or adverse effects, the safety and metabolic outcome of elective conversion from tacrolimus to cyclosporine has not previously been examined. METHODS: Conversion from tacrolimus to cyclosporine was performed in 19 recipients of cadaver renal transplants at 3-6 months after transplantation. Pharmacokinetic profiles and biochemical studies were performed three times, in steady state, before, and after conversion. RESULTS: Patient and graft survival was 100% at 3 months after conversion, with no rejection episodes. Three patients have been subsequently converted back to tacrolimus, two for rejection and one for hirsutism. There were no significant changes in creatinine, urate, or blood sugar levels after conversion, but the mean plasma magnesium rose from 0.73 (0.63-0.97) to 0.82 (0.65-1) mmol/L (P=0.037), and the mean plasma cholesterol rose from 5.2 (3.4-6.8) to 5.5 (3.8-7.6) mmol/L (P=0.033). Pharmacokinetic profiles were measured before and after conversion, and showed that cyclosporine (Neoral) exhibited significantly less interpatient and intrapatient variability than tacrolimus, for area under the curve (AUC), maximum concentration after dose (Cmax), minimum concentration after dose (Cmin), and time to maximum concentration (Tmax). CONCLUSION: This is the first study that has examined the outcome of conversion from tacrolimus- to cyclosporine-based immunosuppression in stable patients after renal transplantation. This conversion was performed without early immunological hazard, but there was a small rise in blood cholesterol levels after conversion. Pharmacokinetic studies showed that cyclosporine in the form of Neoral exhibited less inter- and intrapatient variability than tacrolimus, although this is of uncertain clinical significance.

Recurrent pyogenic cholangiohepatitis.

Three cases of complicated oriental cholangiohepatitis are described in patients of Asian origin. The development of high biliary strictures in two patients required liver resection; in the third patient the process was complicated by a presumed bile duct malignancy. Oriental cholangiohepatitis may be expected in UK surgical practice given the increased frequency of migration from Asia.
