Therapeutic effect of Tripterygium wilfordii on proteinuria associated with sirolimus in renal transplant recipients.

Sirolimus (SRL) is a potent immunosuppressive drug used to prevent acute allograft rejection after renal transplantation. Nevertheless, the occurrence of proteinuria has recently been recognized among patients on SRL-based therapy. The aim of this study was to investigate the therapeutic effects of Tripterygium wilfordii Hook F. (T II) on proteinuria associated with SRL in renal transplant recipients. According to accepting T II, 36 recipients were divided into 2 groups: T II group (n = 21) and valsartan group (n = 15). The T II group was administered 1 mg/kg/d, and the valsartan group, 80 mg twice per day for 12 months. Efficiency was then evaluated. Complete remission: proteinuria decreased by >50%; partial remission: proteinuria decreased by 20% to 50%; ineffective: proteinuria decreased by <20%. Upon 12-month follow-up, the total effective rates in the T II group and the valsartan group were 95.2% and 86.7% (P < .05), respectively. Twenty of 21 patients with proteinuria in the T II group were negative at 3-month follow-up with disappearance of edema. There were some adverse events that had greater incidence rates in the valsartan group compared with the T II group, such as hyperkalemia (26.7% vs 4.8%). We concluded that the application of T II markedly reduced proteinuria associated with SRL in renal transplant patients.

Clinical trial of Tripterygium Wilfordii Hook F. in human kidney transplantation in China.

OBJECTIVE: In this study, the effects of Triptergium Wilfordii Hook F.(T II) were assessed on human kidney allograft rejection and long-term survival. METHODS: This study compared treatment with T II(T II group, n=121) to that without T II(control group, n=102) among adult first cadaveric renal transplant recipients. The T II cohort of 121 recipients were divided into a regular dosage group (n=82) and a double dosage group (n=39). No antibody induction was administered to any patient. RESULTS: Biopsy-proven early acute allograft rejection occurred in 4.1% of patients in the T II group versus 24.5% of patients in the control group. No rejection or repeated rejections occurred in the double dosage group at 3 months after transplantation. Acute rejection episodes were milder in the T II than the control group. The incidence of CD25+ cells>10/ mm3 in the allografts at 3 months after transplantation was lower in the T II group than the control group, 15% and 50%, respectively. All patients tolerated T II well over the 5 years of this study. The 5-year graft survival censored for death with function was 96.7% in the T II group and 80.4% in the control group. CONCLUSION: T II was effective to prevent renal allograft rejection and increase long-term renal allograft survival among adult cadaveric renal transplant recipients.

[Effects of baoshen pill in treating chronic renal failure with long-term hemodialysis].

A clinical trial, to evaluate the effects of Baoshen Pill (Rheum palmatum extract, RPE) on hemodialytic patients was conducted. 42 cases with terminal stage of renal failure (Scr < 10 ml/min) on HD were divided at random into RPE treated group and control group. The results showed there were no statistically significant differences between two groups for Scr or BUN. Serum levels of TC, LDL-c, apo B and apo B/apo A1 dropped down and HDL-c, apo A1, albumin, pro-albumin and fibrinectin increased during the follow-up period (P < 0.05) in the treated patients. It is considered that the mechanisms of RPE in preventing chronic renal failure were not the action of whole body. Improving serum levels of albumin, lipoprotein, apolipoproteins might play important role in treatment.
