Studies on Eleven Kidney Transplants from Non-Heart-Beating Donors

This study was performed to analyze postoperative courses and complications, retrospectively, following transplants from non-heart-beating donors and to examine the correlation between early graft function and clinical parameters. We experienced 11 cases of kidney transplants from non-heart-beating donors during the period from April 1995 to May 2003. Warm ischemic time was less than 30 min in all cases, and total ischemic time ranged from 8.4 hours to 27.9 hours. Rejection reactions occurred in seven cases, two of which were vascular rejections. Infectious disease complications included CMV in two cases, interstitial pneumonia in one case and fungal infection in one case. One patient died from interstitial pneumonia, and three patients had to be restarted on dialysis due to loss of function of the grafted kidney. The remaining seven patients all made full recoveries. All of the 16 patients who underwent living related kidney transplantations during the same period made full recoveries. Both the donor's gender and the latest creatinine level of the donor influenced the posttransplant dialysis period. The posttransplant dialysis period significantly influenced the creatinine level one month after transplant. These results suggest that patients who undergo kidney transplants from nonheart-beating donors have higher rates of complications than patients who undergo living related kidney transplantation. It is important that, in cases where the donor's creatinine level is high, especially when the donor is male, the kidney is carefully retrieved and transported to the recipent hospital to shorten the ischemic period as much as possible

Studies on Post-Transplant Dyslipidemia in Kidney Transplant Patients

This study was performed to retrospectively compare changes in the levels of total cholesterol, non-HDL cholesterol, triglycerides, and immunosuppressive drugs, cyclosporine A and steroids in patients with living-relation renal transplants with those from non-heart-beating donors. We experienced 11 cases of kidney transplants from non-heart-beating donors during the period from April 1995 to May 2003. We evaluated 13 cases of kidney transplants from living-relation donors during the same period. The immunosuppressants used included mainly cyclosporine A as well as mycophenolate mofetil or azathioprine, steroid and ALG, or basiliximab. Over-night fasting lipids (total cholesterol, triglycerides and HDL cholesterol) were studied before renal transplantation and repeated after renal transplantation at 1, 3, 6 and 12 months. The levels of total cholesterol and triglycerides remained in the normal range before transplantation. However, the levels of total cholesterol increased siginificantly 1 and 3 months after transplantation from non-heart-beating donors and remained at higher levels up to 12 months after transplantation. A similar pattern in the levels of triglycerides was observed. The levels of HDL cholesterol remained unchanged and stayed in the normal range before and 1, 3, 6, and 12 months after transplantation from non-heart-beating donors. On the other hand, significant increases in non-HDL cholesterol were observed 3 and 6 months after transplantation from non-heart-beating donors. After transplantation from living-relation donors, levels of total cholesterol, triglycerides, and non-HDL cholesterol remained unchanged and remained in the normal range up to 12 months after transplantation. Although there were no significant differences in the total dosage of cyclosporine A between the patients with living-relation donors and those with non-heart-beating donors, a significant increase in the total dosage of methylprednisolone was observed in patients with non-heart-beating donors compared with those in the

Study on Eight Patients with Malignant Tumors after Renal Transplantation

The high incidence of cancer after renal transplantation is now a critical concern since the graft survival rate has been improved extensively. We experienced 9 malignancies in 8 patients out of 168 recipients up to December 31, 1999 in our hospital, consisting of a case of gastric plasmacytoma and cases of cancer in the liver (2), thyroid (2), prostate (1), breast (1), sigmoid colon (1) and gall-bladder (1). Two patients were diagnosed as having tumors within 3 months after transplantation, suggesting post-transplant acceleration of growth of the latent tumors. The other patients were diagnosed at an average of 128 months, ranging from 84 to 263 months after transplant. Two patients died of gastro-intestinal bleeding and acute heart failure. Four patients died directly of progressive neoplasm within 3 months after diagnosis. These results suggest that the course of malignancies developing in post-transplant recipients is more aggressive than that expected in non-transplant patients, and it is very important to intensively follow long-term surviving cases to detect the malignant tumors as early as possible
