Renal function of donors and recipients after living donor kidney transplantation in a Chinese cohort / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Living donor kidney transplantation (LKT) has been booming in China. This study aimed to elucidate the renal function of both Chinese donors and recipients after the donation and transplantation.</p><p><b>METHODS</b>One hundred and forty-one pairs of donors and recipients for LKT were randomly selected and followed up for up to seven years. The donors' and recipients' renal function was recorded before and after operation.</p><p><b>RESULTS</b>The donors presented a mean age of (43.9 ± 7.5) years at donation. The female contributed 101/141 (71.6%) in all donors, and no effect was shown between genders on healthy donors' renal function. The donors' glomerular filtration rates (GFR) were (119.5 ± 20.4) ml/min, (85.2 ± 17.6) ml/min, (87.2 ± 15.9) ml/min, (82.1 ± 14.6) ml/min and (83.0 ± 13.7) ml/min preoperatively, and for five days, three months, one year and beyond one year after the operation. The donors for the period of 1 - 3 years, 3 - 5 years and more than 5 years after donation showed GFR as (83.9 ± 12.7) ml/min, (83.0 ± 17.6) ml/min, and (80.9 ± 20.8) ml/min, respectively, no statistically significant difference was found. Moreover, no significant clinical changes in blood pressure and proteinuria were found among the donors. In the recipients, delayed graft function (DGF) rate was 6.4%, acute rejection rate was 11.3%, and GFR were (66.5 ± 16.4) ml/min, (73.2 ± 19.6) ml/min and (63.9 ± 18.6) ml/min respectively at three months, one year and beyond one year post-transplantation respectively.</p><p><b>CONCLUSION</b>The donors/recipients of LKT in Chinese population experience well-functioning remaining/donor kidneys.</p>

Technology and application of simultaneous pancreas-kidney transplantation with modified enteric drainage / 中华外科杂志

<p><b>OBJECTIVE</b>To report the modified technique and the short-term results of simultaneous pancreas-kidney transplantation (SPK) with the enteric drainage (ED) of exocrine secretions.</p><p><b>METHODS</b>From June 2000 to August 2006, thirty-eight patients with diabetes complicated with uremia underwent SPK. The pancreas graft was placed intraperitoneally with exocrine secretions drained into the proximal jejunum without Roux-en-Y procedure. The mean cold ischemic times of pancreas and kidney were (10 +/- 2.0) h and (7 +/- 2.0) h, respectively. Quadruple immunosuppressive therapy with antilymphocyte globulin or anti-CD25 monoclonal antibody, tacrolimus, mycophenolate mofetil and steroids was adopted except one patient.</p><p><b>RESULTS</b>The 6-month survival rates of patients and grafts were both 97.4% after transplantation. All patients achieved insulin-free euglycemia at (7 +/- 6.9) d postoperative except one. For preoperative patients, mean fasting insulin and C-peptide values were (9 +/- 8.1) mU/L and (6 +/- 4.5) mU/L. After operation, fasting insulin and C-peptide values of patients were (12 +/- 5.8) mU/L and (6 +/- 4.7) mU/L, respectively, which peaked to an insulin level of (57 +/- 43.0) mU/L and a C-peptide level of (11 +/- 6.8) mU/L with stimulation. There were eight cases of delayed renal graft function. All other patients achieved immediate renal graft function. No graft losses occurred due to leakage or intra-abdominal infection. The most common surgical complications were wound infection (n = 12), enteric anastomostic hemorrhage (n = 5) and perirenal hemorrhage (n = 2). Three patients (7.9%) had been reoperated for the reasons of intra-abdominal hemorrhage and perirenal hemorrhage.</p><p><b>CONCLUSIONS</b>SPK is an effective treatment option for selected patients with diabetes mellitus and approaching end-stage renal disease. Enteric exocrine drainage by direct side-to-side anastomosis (without Roux-en-Y) seems to be a simple and reliable technique.</p>
