OBJECTIVE: To evaluate the use of elderly donors in liver transplantation (LT) and identify risk factors associated with a worse outcome. SUMMARY BACKGROUND DATA: Use of livers from very old donors could expand the donor pool but is not universally implemented. METHODS: This is a retrospective, single-center medical record review. From January 2001 to December 2014, 1354 LTs were performed. After exclusion of donors <18 years, ABO-incompatible LT, re-LT and UNOS 1 status patients, LT recipients were stratified into 2 groups based on donor age: 18-69 (n=692) vs...

The present study tests a hypothesis that cardioprotective effects mediated by autologous adipose-derived stem cells (ADSC) in rats afflicted with insulin-dependent diabetes mellitus (IDDM), may be synergistically enhanced by oral treatment with green tea epigallocatechin gallat (ECCG). Wistar rats were divided into sham, DM, DM+ADSC (autologous transplanted 1x106 cells/rat) and DM+ADSC+E (E, green tea oral administration EGCG). Heart tissues were isolated for all rats and investigations were performed after 2-months treatment...

OBJECTIVES: Metabolic syndrome components, such as being overweight or having hypertension, hyperlipidemia, or diabetes mellitus, are common complications after liver transplant in pediatric patients with probable multifactorial causes and increase the risk of cardiovascular complications in adulthood. In this study, our aim was to evaluate the prevalence of these components both before and after transplant surgery. MATERIALS AND METHODS: Our study included all children having liver transplant at our institution over a period of 20 years who were under 18 years old and had at least 6 months of posttransplant follow-up...

Since the inception of pancreas transplant as a treatment for type 1 diabetes mellitus, there has been considerable debate about the best way to manage exocrine secretions and monitor patients for graft rejection. For patients who undergo bladder exocrine drainage of a pancreatic allograft, a bladder-to-enteric drainage conversion can serve as a rescue procedure in case of anastomotic leaks or other complications. However, this procedure is associated with its own complications, including a rarely described enterovesical fistula...

PURPOSE OF REVIEW: Patients with type 1 diabetes and end stage renal disease face a complex choice when considering the relative risks and benefits of kidney transplant alone with or without subsequent pancreas after kidney transplant (PAK) or simultaneous kidney pancreas transplant (SPK). RECENT FINDINGS: SPK is considered the optimal treatment regarding long-term patient survival, but when also faced with the option of living donor kidney transplant with the potential for PAK later, the ideal option is less clear...

Type I diabetes mellitus is characterized by the destruction of the insulin producing beta cells within the pancreas by the immune system. After the success of Edmonton protocol, islet transplantation has shown to be a promising therapy, but with the Achilles´ heel of the need of using immunosuppressive drugs. Currently, cell encapsulation technology represents a real alternative to protect transplanted islets from the host´s immune attack. Although preliminary in vitro studies with encapsulated cells have been traditionally performed under static conditions in terms of viability and efficiency, these static cultures do not represent a close approach to in vivo environments...

BACKGROUND Development of post-transplant diabetes mellitus after kidney transplant (PTDM) significantly increases kidney graft loss and mortality. Several risk factors for PTDM have been reported, including Hispanic ethnicity and the use of calcineurin inhibitors and corticosteroids. The incidence and impact of PTDM in the Hispanic kidney transplant population is unknown. MATERIAL AND METHODS We retrospectively reviewed the medical records of 155 Hispanic and 124 Caucasian patients, who were not diabetics and underwent kidney transplant between January 2006 and December 2011...

Roux-en-Y gastric bypass (RYGB) and duodenal jejunal bypass (DJB), two different forms of bariatric surgery, are associated with improved glucose tolerance, but it is not clear whether the gut microbiota contributes to this effect. Here we used fa/fa rats as a model of impaired glucose tolerance to investigate whether (i) the microbiota varies between fa/fa and nondiabetic fa/+ rats; (ii) the microbiota of fa/fa rats is affected by RYGB and/or DJB; and (iii) surgically induced microbiota alterations contribute to glucose metabolism...

BACKGROUND: In patients with type 1 diabetes, allogeneic islet transplantation can provide normal HbA1c concentrations, but it requires immunosuppression. Transplanting encapsulated islets into the peritoneal cavity could reduce or eliminate the need for immunosuppression. One of the uncertain features of intraperitoneal islet transplantation is the difficulty of measuring C-peptide concentrations in peripheral blood, which is often used for the marker of islet function. We hypothesized that secreted C-peptide from intraperitoneally transplanted islets was mostly consumed in the peritoneal cavity, which resulted in low C-peptide concentrations in peripheral blood...

Iatrogenic pancreatic cancer metastasis after islet infusion is a potential risk of islet autotransplantation performed after pancreatectomy. To model this risk islets and/or pancreatic exocrine clusters obtained from a genetically engineered mouse model for pancreatic ductal adenocarcinoma (the LSL-Kras(G12D/+) ;LSL-Trp53(R172H/+) ;Pdx-1-Cre, termed KPC mouse) were transplanted via the portal vein in syngeneic wild type (WT) severely diabetic recipients in the following treatment groups: group A (n=11) received KPC exocrine clusters in volume equal to 250 equivalent islets (IEQs); group B (n=12) received 250 WT IEQs mixed with KPC exocrine clusters (1:1 volume ratio); group C (n=5) received 250 KPC IEQs and group D (n=7) received 250 wild type IEQs...

Myeloma cast nephropathy is a major complication of multiple myeloma. Recent evidence has demonstrated that the earlier induction of bortezomib-based chemotherapy with plasma exchange (PE) provides better results for kidney function and patient survival. Due to its non-selectivity, PE with albumin replacement carries the risk of fibrinogen loss, leading to bleeding. We herein report a case of successful treatment of myeloma cast nephropathy using bortezomib-based chemotherapy and selective PE. A 61-year-old woman who had a 20-year history of type II diabetes mellitus was admitted to our hospital for the evaluation of hypercalcemia, severe kidney dysfunction, and anemia...

Among the innovations for the treatment of type 1 diabetes, islet transplantation is a less invasive method of treatment, although it is still in development. One of the greatest barriers to this technique is the low number of pancreas donors and the low number of pancreases that are available for transplantation. Rodent models have been chosen in most studies of islet rejection and type 1 diabetes prevention to evaluate the quality and function of isolated human islets and to identify alternative solutions to the problem of islet scarcity...

Islet transplantation offers a minimally-invasive approach for beta cell replacement in diabetic patients with hypoglycemic unawareness. Attempts at insulin independence may require multiple islet re-infusions from distinct donors, thus increasing the risk for allogeneic sensitization. Currently, solid organ pancreas transplant is the only remaining surgical option following failed islet transplantation in the US. However, the immunologic impact of repeated exposure to donor antigens on subsequent pancreas transplantation is unclear...
