Improved short- and long-term survival of liver transplant recipients has led to increased focus on complications of both the early and late posttransplant periods. A variety of metabolic complications have been observed in the post-orthotopic liver transplant population, including hypertension, hyperlipidemia, obesity, diabetes mellitus, nonalcoholic fatty liver disease, and nonalcoholic steatohepatitis. Although only a small proportion of patients experience metabolic complications prior to transplantation, the prevalence of these complications posttransplantation reaches or exceeds that of the general population...

Previous studies on patient and allograft outcomes of obese kidney transplant recipients (KTRs) remain controversial. To what extent obesity-related comorbidities contribute to adverse outcomes, however, hasn't been addressed. We studied all KTRs from 2005 to 2012. 29 (4%), 317 (48%), 217 (33%), 76 (12%), and 21 KTRs (4%) were identified as underweight, normal-weight, overweight, obese, and morbid obese, respectively. 33 of 97 obese KTRs (34%) had pre-existent diabetes. Samples were collected before transplantation and at +1, +2, +3months posttransplantation...

BACKGROUND: Dysglycemia (encompassing impaired glucose tolerance and diabetes mellitus) arising after renal transplantation is common and confers a significant cardiovascular mortality risk. Nonetheless, the pathophysiology of posttransplant dysglycemia is not well described. The aim of this study was to prospectively and comprehensively assess glucose handling in renal transplant recipients from before to 12 months after transplantation to determine the underpinning pathophysiology. MATERIALS AND METHODS: Intravenous and oral glucose tolerance testing was conducted before and at 3 and 12 months posttransplantation...

BACKGROUND: Transplantation (NTX) associated ischemia-reperfusion-mechanisms and the predisposition for insulin resistance are discussed as causes of a posttransplantation diabetes mellitus (PTDM). Furthermore, immunosuppressants can have a damaging effect on insulin secretion. METHODS: 55 metabolically healthy patients with an endstage renal disease (age 52 ± 14 years, body mass index 27 ± 5 kg / m(2), blood pressure 137 ± 15/82 ± 11 mmHg) were included in a prospectively cohort study...

BACKGROUND: Recent studies suggest that the combination of tacrolimus (TAC) and everolimus (EVL) could become a viable option for use as standard maintenance immunosuppression in non-highly sensitized kidney transplant recipients. METHODS: We conducted a single-center, open-label, randomized pilot trial comparing two maintenance immunosuppression regimens in non-highly sensitized, adult, primary kidney transplant recipients: (TAC/EVL, Group A) vs our standard maintenance regimen of TAC plus enteric-coated mycophenolate mofetil (TAC/EC-MPS, Group B)...

BACKGROUND: Posttransplantation diabetes mellitus (PTDM) is an important metabolic complication after renal transplantation. Activation of the innate immune system via toll-like receptors (TLRs) is implicated in the pathogenesis of insulin resistance and deficiency. Although links between diabetes, dysregulated innate immune responses, and the TLR signaling pathway have been reported, no study so far has investigated their associations with PTDM. In this study, we ascertained whether single nucleotide polymorphisms (SNPs) in TLRs are associated with PTDM in the Korea population...

BACKGROUND: Most current scoring tools to predict allograft and patient survival upon kidney transplantion are based on variables collected posttransplantation. We developed a novel score to predict posttransplant outcomes using pretransplant information including routine laboratory data available before or at the time of transplantation. METHODS: Linking the 5-year patient data of a large dialysis organization to the Scientific Registry of Transplant Recipients, we identified 15 125 hemodialysis patients who underwent first deceased transplantion...

BACKGROUND: Previous reports indicate that posttransplantation diabetes mellitus (PTDM) is associated with overall renal graft loss, but not death-censored graft loss. METHODS: In this single-center retrospective cohort study of 2749 adult Norwegian renal transplant recipients, transplanted between 1999 and 2011, we estimated overall and death-censored renal graft loss hazard ratios in patients diagnosed with PTDM, impaired glucose tolerance and diabetes before transplantation, using multivariable Cox proportional hazard regression analysis...

BACKGROUND: The maintenance or expansion of regulatory T (Treg) cells has a fundamental role in the achievement of immunological tolerance after transplantation. Here we aimed to determine mechanisms of human Treg cell depletion and reconstitution after anti-CD25 monoclonal antibody (mAb) treatment. METHODS: Seventeen patients with type 1 diabetes who received pancreatic islet transplantation and anti-CD25 mAb as induction therapy were studied. RESULTS: We observed an almost complete depletion of Treg cells after injection of anti-CD25 mAb...

BACKGROUND: Mammalian target of rapamycin inhibitors (mTORi) play an essential role as novel immunosuppressive agents in kidney transplantation (KT). Treatment cessation usually occurs after adverse effects occur. We investigated the risk factors associated with withdrawal of mTORi in KT recipients and evaluated the outcomes related to the withdrawal. METHODS: The study enrolled KT recipients being followed up in a medical center in southern Taiwan from January 1999 through December 2014...

OBJECTIVE: Development of posttransplantation diabetes (PTDM) is characterized by reduced insulin secretion and sensitivity. We aimed to investigate whether hyperglucagonemia could play a role in PTDM and to examine the insulinotropic and glucagonostatic effects of the incretin hormone glucagon-like peptide 1 (GLP-1) during fasting and hyperglycemic conditions, respectively. RESEARCH DESIGN AND METHODS: Renal transplant recipients with (n = 12) and without (n = 12) PTDM underwent two separate experimental days with 3-h intravenous infusions of GLP-1 (0...

Current diagnostic criteria for post-transplantation diabetes mellitus (PTDM) are either fasting plasma glucose ≥7.0 mmol/l (≥126 mg/dl) or postchallenge plasma glucose ≥11.1 mmol/l (≥200 mg/dl) 2 h after glucose administration [oral glucose tolerance test (OGTT) criterion]. In this retrospective cohort study of 1632 renal transplant recipients (RTRs) without known diabetes mellitus at the time of transplantation, we estimated mortality hazard ratios for patients diagnosed with PTDM by either conventional glucose criteria or the proposed glycated haemoglobin (HbA1c) criterion [HbA1c ≥6...

BACKGROUND: Patients with HNF1B mutations develop progressive chronic renal failure, diabetes mellitus (40-50%), and liver tests abnormalities (40-70%). In HNF1B patients who reach end-stage renal disease, single kidney transplantation (SKT) or combined kidney-pancreas transplantation can be considered. METHODS: A retrospective multicenter study including 18 HNF1B patients receiving SKT or kidney-pancreas transplantation, and in vitro experiments including the characterization of the HNF1B expression after calcineurin inhibitor (CNI) exposure...

Agonists of growth hormone-releasing hormone (GHRH) have been previously reported to promote growth, function, and engraftment of islet cells following transplantation. Here we evaluated recently synthesized GHRH agonists on the proliferation and biological functions of rat pancreatic β-cell line (INS-1) and islets. In vitro treatment of INS-1 cells with GHRH agonists increased cell proliferation, the expression of cellular insulin, insulin-like growth factor-1 (IGF1), and GHRH receptor, and also stimulated insulin secretion in response to glucose challenge...
