Pancreas Recipients (pancreas + recipient)
Selected AbstractsReactive hypoglycaemia following GLP-1 infusion in pancreas transplant recipientsDIABETES OBESITY & METABOLISM, Issue 8 2010M. R. Rickels The aim of the study was to determine whether reactive hypoglycaemia in pancreas transplant recipients that followed administration of glucagon-like peptide-1 (GLP-1) was associated with excessive insulin, insufficient glucagon, or both. Methodology involved six portally drained pancreas recipients who received GLP-1 (1.5 pmol/kg/min) or placebo infusion on randomized occasions during glucose-potentiated arginine testing. The second subject developed symptomatic hypoglycaemia [plasma glucose (PG) 42 mg/dl] 1 h after GLP-1 administration; subsequent subjects received intravenous glucose following GLP-1, but not placebo, infusion for PG levels <65 mg/dl. Following GLP-1 vs. placebo infusion, PG was lower (58 ± 4 vs. 76 ± 5 mg/dl; p < 0.05) despite administration of intravenous glucose. During hypoglycaemia, insulin levels and the insulin-to-glucagon ratio were greater after GLP-1 vs. placebo infusion (p < 0.05), while glucagon did not vary. It can be concluded from the study that GLP-1 can induce reactive hypoglycaemia in pancreas transplant recipients through excessive insulin secretion associated with an increased insulin-to-glucagon ratio. [source] Review article: Managing bone complications after kidney transplantationNEPHROLOGY, Issue 4 2009RAHUL MAINRA SUMMARY Chronic kidney disease mineral and bone disorder (CKD-MBD) describes the laboratory, bone and vascular abnormalities that exist in patients with CKD stages 3,5D and that may persist after transplantation. Persisting abnormalities of bone turnover and abnormal mineralization, together with bone mineral density (BMD) loss from glucocorticoids, may all predispose to a loss of structural integrity and increased fracture risk in kidney and kidney pancreas recipients. Vitamin D, calcitriol, calcitonin and bisphosphonates have all been used to preserve BMD following transplantation, despite a lack of safety data and the potential for some of these drugs to cause harm. A limited number of post-transplant studies utilizing these drugs have not yet documented improved fracture prevention or fracture-related mortality and have not considered allocation based on risk factors for fracture or markers of bone turnover. Targeted allocation of the available therapies based on a stratification of risk appears warranted. This might be achieved using an algorithm incorporating BMD, X-ray evaluation, laboratory investigations including bone turnover markers and the assessment of standard fracture risk factors at the time of and soon after transplantation. This approach, which is similar to protocols used in the general population, may result in more effective management of patients and fewer adverse effects such as adynamic bone disease. Although BMD is a surrogate for fracture risk in the general population it is not validated in this transplant population. Consequently, such an approach should be confirmed by studies that include bone biopsy data and an evaluation of patient level outcomes.

McCullough Although the number of candidates on the kidney transplant waiting list at year-end rose from 40 825 to 76 070 (86%) between 1998 and 2007, recent growth principally reflects increases in the number of patients in inactive status. The number of active patients increased by ,only' 4510 between 2002 and 2007, from 44 263 to 48 773. There were 6037 living donor and 10 082 deceased donor kidney transplants in 2007. Patient and allograft survival was best for recipients of living donor kidneys, least for expanded criteria donor (ECD) deceased donor kidneys, and intermediate for non-ECD deceased donor kidneys. The total number of pancreas transplants peaked at 1484 in 2004 and has since declined to 1331. Among pancreas recipients, those with simultaneous pancreas-kidney (SPK) transplants experienced the best pancreas graft survival rates: 86% at 1 year and 53% at 10 years. Between 1998 and 2006, among diabetic patients with end-stage renal disease (ESRD) who were under the age of 50 years, 23% of all and 62% of those waitlisted received a kidney-alone or SPK transplant. In contrast, 6% of diabetic patients aged 50,75 years with ESRD were transplanted, representing 46% of those waitlisted from this cohort. Access to kidney-alone or SPK transplantation varies widely by state. [source] Transmission of Anaplastic Large Cell Lymphoma via Organ Donation After Cardiac DeathAMERICAN JOURNAL OF TRANSPLANTATION, Issue 1 2008J. W. Harbell Recently, donation after cardiac death (DCD) has been encouraged in order to expand the donor pool. We present a case of anaplastic T-cell lymphoma transmitted to four recipients of solid organ transplants from a DCD donor suspected of having bacterial meningitis. On brain biopsy, the donor was found to have anaplastic central nervous system T-cell lymphoma, and the recipient of the donor's pancreas, liver and kidneys were found to have involvement of T-cell lymphoma. The transplanted kidneys and pancreas were excised from the respective recipients, and the kidney and pancreas recipients responded well to chemotherapy. The liver recipient underwent three cycles of chemotherapy, but later died due to complications of severe tumor burden. We recommend transplanting organs from donors with suspected bacterial meningitis only after identification of the infectious organism. In cases of lymphoma transmission, excision of the graft may be the only chance at long-term survival. [source] |
