1/87. Acute torsion of the renal transplant after combined kidney-pancreas transplant.BACKGROUND: Surgical complications after combined kidney and pancreas transplantation are a major source of morbidity and mortality. Complications related to the pancreas occur with greater frequency as compared to renal complications. The occurrence in our practice of two cases of renal infarction resulting from torsion about the vascular pedicle led to our retrospective review of similar vascular complications after combined kidney and pancreas transplantation. methods: charts were reviewed retrospectively, and two patients were identified who experienced torsion about the vascular pedicle of an intra-abdominally placed renal allograft. RESULTS: Two patients who had received combined intraperitoneal kidney and pancreas transplantation presented at 16 and 11 months after transplant, respectively, with abdominal pain and decreased urine output. One patient had radiological documentation of abnormal rotation before the graft loss; unfortunately, the significance of this finding was missed. diagnosis was made in both patients at laparotomy, where the kidneys were infarcted secondary to torsion of the vascular pedicle. Both patients underwent transplant nephrectomy and subsequently received a successful second cadaveric renal transplant. CONCLUSIONS: The mechanism of this complication is a result of the intra-abdominal placement of the kidney, length of the vascular pedicle, excess ureteral length, and paucity of adhesions secondary to steroid administration. These factors contribute to abnormal mobility of the kidney. Technical modifications such as minimizing excess ureteral length and nephropexy may help to avoid this complication.- - - - - - - - - - ranking = 1keywords = kidney (Clic here for more details about this article) |
2/87. cyclosporine disposition and long-term renal function in a 500-pound kidney transplant recipient.Patient size has been suggested as a risk factor in kidney transplantation. We have followed a recipient of a cadaver kidney who became massively obese (232 kg, 511 lbs) 5 years posttransplantation. He has maintained stable renal function with no rejection episodes and at 5 years has a measured serum creatinine of 2.2 mg/dL, creatinine clearance 42 mL/min, and urinary protein excretion of 320 mg/24h. Both oral and intravenous cyclosporine (Sandimmune) pharmacokinetic studies were done on a steady-state dose of 150 mg, which represents 0.65 mg/kg per dose. The patient exhibited very high bioavailability, F = 95%, and an oral elimination T1/2 of over 21 hours. These data confirm that stable cyclosporine delivery in very obese recipients can be sustained by dosing normalized to the ideal body weight and trough level monitoring.- - - - - - - - - - ranking = 0.6keywords = kidney (Clic here for more details about this article) |
3/87. Bilateral emphysematous pyelonephritis caused by candida infection.Emphysematous pyelonephritis is a rare, often severe infection of one or both kidneys that is most often caused by bacterial infection. Surgical intervention is often necessary. We describe a case of a diabetic patient with bilateral emphysematous pyelonephritis caused by candida infection that was treated conservatively. Renal function recovered almost completely in spite of giving a potential nephrotoxic drug for 6 weeks.- - - - - - - - - - ranking = 0.1keywords = kidney (Clic here for more details about this article) |
4/87. Successful living related simultaneous pancreas-kidney transplant between identical twins.Simultaneous pancreas-kidney transplant from living donors has been recently proposed as an effective therapeutic option in selected uremic patients with type I diabetes. We report the first simultaneous pancreas-kidney transplant performed between identical twins. Posttransplant, the recipient has been maintained on low dose cyclosporine to avoid recurrent auto-immune insulitis. At the 1-year follow-up, both donor and recipient are well with normal renal function and excellent glucose control. Simultaneous pancreas-kidney transplant between identical twins can be performed successfully using cyclosporine to prevent recurrent auto-immune insulitis.- - - - - - - - - - ranking = 0.7keywords = kidney (Clic here for more details about this article) |
5/87. Successful obstetric outcome after simultaneous pancreas and kidney transplantation.A 34-year-old woman became pregnant two years after having a simultaneous pancreas and kidney (SPK) transplantation, necessitated by type 1 diabetes and end-stage renal disease. The pregnancy was uneventful until 30 weeks' gestation, when she developed pancreatitis and a worsening of mild hypertension. A healthy 1700 g boy was delivered by caesarean section at 34 weeks' gestation. This is the first report of a successful pregnancy after SPK transplantation in australia.- - - - - - - - - - ranking = 0.5keywords = kidney (Clic here for more details about this article) |
6/87. gastroparesis and jejunal feeding.A kidney transplant patient with diabetic gastroparesis was effectively treated by jejunal feeding. The patient, a 31-year-old woman, has a complicated medical history, with insulin-dependent diabetes mellitus. Complications include kidney failure followed by transplantation, bilateral knee amputations, and being registered blind. She was admitted with nausea and vomiting for the previous 6 days; the provisional diagnosis was diabetic gastroparesis. Various treatments were tried, including several prokinetic drugs and total parenteral nutrition. The total parenteral nutrition provided most of the patient's nutritional requirements, and, only slight weight loss was observed. Nothing seemed to improve the symptoms of vomiting. An endoscopic retrograde cholangiopancreatography, a radiographic examination of the bile and pancreatic ducts, was performed to exclude obstruction. At the same time, having found nothing, a gastrostomy was placed with a jejunal extension. Feeding was established within 3 days. Her weight remained stable after 7 weeks of jejunal feeding. She had started to increase her oral intake of solid foods and fluids. By 8 weeks, she was taking a full oral diet and fluids. Now, 14 weeks after the placement of the gastrostomy tube with the jejunal extension, she is doing well. Her weight remains stable and her oral intake is excellent. Her diabetes is under control. After 22 weeks, the gastrostomy was removed. After this success with jejunal feeding when all other treatments had failed, this treatment could be used to treat future diabetic gastroparesis. Slow introduction of the feed seems to help toleration.- - - - - - - - - - ranking = 0.2keywords = kidney (Clic here for more details about this article) |
7/87. Evidence of recurrent type I diabetes following HLA-mismatched pancreas transplantation.Type 1 diabetes mellitus is considered as an autoimmune disease against beta cells. Diabetes recurrence after pancreas transplantation is well known in HLA-identical twins while it is rarely reported in recipients of cadaveric pancreatic grafts. In the present case report, diabetes recurrence occurred in a recipient who underwent cadaveric combined pancreas kidney transplantation. Seven years after transplantation the patient exhibited progressive hyperglycemia needing insulin therapy while the renal graft was well functioning. The diagnosis of recurrent disease was obtained on the histological features such as selective loss of beta cells without clear signs of insulitis and on the presence of markers (GAD 65 and IA-2) for humoral autoimmunity. It is intriguing that, at the time of recurrence of type 1 diabetes, the patient had stopped steroids and azathioprine, while only cyclosporine was maintained as immunosuppressive treatment. Our case report underlines the relevance of studying the humoral autoimmune response directed to islet autoantigens in cadaveric pancreas allograft recipients. Furthermore, it suggests that an efficient immunosuppressive treatment after transplantation may be able to reduce the autoimmune response against the pancreatic allograft.- - - - - - - - - - ranking = 0.1keywords = kidney (Clic here for more details about this article) |
8/87. Clopidogrel-associated thrombotic thrombocytopenic purpura/hemolytic uremic syndrome in a kidney/pancreas transplant recipient.BACKGROUND: We present a case report of thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS) developing in a kidney/pancreas transplant recipient after the initiation of treatment with clopidogrel for symptomatic coronary artery disease. methods: A 35-year-old male kidney/pancreas recipient developed unstable angina 5 years after transplantation. The patient was treated with clopidogrel as adjunct therapy. A TTP/HUS condition developed, was diagnosed early, and successfully reversed with the implementation of plasmapheresis and cessation of clopidogrel and cyclosporine A. RESULTS: The patient continues taking cyclosporine A with good renal function 6 months after the incident, and successfully underwent coronary artery by-pass grafting 3 months after the event. DISCUSSION: This case demonstrates that early identification and treatment can reverse the TTP/HUS process associated with thienopyridine-derived agents. We strongly recommend that drugs of the thienopyridine class be used cautiously in transplant recipients, especially those taking calcineurin-inhibitors.- - - - - - - - - - ranking = 0.6keywords = kidney (Clic here for more details about this article) |
9/87. Hyperglycemic pseudorejection in the diabetic transplant patient.serum creatinine elevation in a stable transplant recipient most often suggests rejection of the transplant and requires further evaluation and management. In our series of juvenile diabetic patients who have received kidney transplants, we frequently have observed creatinine elevations in association with hyperglycemia. Correction of the hyperglycemia resulted in return of serum creatinine to normal levels and no rejection therapy was required. To better define this syndrome, 2,734 paired measurements of blood glucose and serum creatinine were obtained in 52 stable post-transplant diabetic patients. A mean increase in blood glucose of 100 mg. per 100 ml. was found to increase serum creatinine by 0.5 mg. per 100 ml. in these patients (r=0.93; p less than or equal to 0.001). Evidence strongly suggests that the pathogenesis of this phenomenon is not a result of a laboratory artifact due to the technique used to determine serum creatinine. The pathogenesis may be due to the increased serum osmolarity and resulting intracellular dehydration associated with hyperglycemia. Recognition of this syndrome is important to all centers participating in the care and management of the diabetic transplant recipient.- - - - - - - - - - ranking = 0.1keywords = kidney (Clic here for more details about this article) |
10/87. A patient with apolipoprotein e2 variant (Q187E) without lipoprotein glomerulopathy.Four apolipoprotein (apo) E variants have been reported to be associated with lipoprotein glomerulopathy (LPG), which is characterized by type III hyperlipoproteinemia (type III HLP) and proteinuria and frequently leads to nephrotic syndrome. We report the histologic findings in the kidneys of a type III HLP patient with an apo E variant, apo E Toranomon, in which the glutamine at residue 187 in apo E is substituted by glutamic acid (Q187E). The patient also had type 2 diabetes mellitus. No evidence of lipoprotein thrombi suggestive of LPG was detected, however, and the histologic diagnosis was diabetic nephrosclerosis. This unique case illustrates that not all apo E variants result in LPG, and the location of mutations in the apo E protein is one of the important determinants for the development of LPG.- - - - - - - - - - ranking = 0.1keywords = kidney (Clic here for more details about this article) |
