Waitlist time for kidney transplantation is long but may be shortened with the utilization of hepatitis C positive allografts. We retrospectively reviewed the course of 36 hepatitis C positive patients awaiting kidney transplantation at two large centers within the same health system, with near-identical care delivery models with the exception of timing of hepatitis C treatment, to determine the impact of timing of hepatitis C treatment on access to transplant, waitlist time and treatment efficacy and tolerability...

Chronic kidney disease is most desirably and cost-effectively treated by renal transplantation, but graft survival is a major challenge. Although irreversible graft damage can be averted by timely treatment, intervention is delayed when early graft dysfunction goes undetected by standard clinical metrics. A more sensitive and specific parameter for delineating graft health could be the viscoelastic properties of the renal parenchyma, which are interrogated non-invasively by Viscoelastic Response (VisR) ultrasound, a new acoustic radiation force (ARF)-based imaging method...

BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is the most common life-threatening genetic disease in humans, affecting approximately 1 in 500 people. ADPKD is characterized by cyst growth in the kidney leading to progressive parenchymal damage and is the underlying pathology in approximately 10% of patients requiring hemodialysis or transplantation for end-stage kidney disease. The two proteins that are mutated in ADPKD, polycystin-1 and polycystin-2, form a complex located on the primary cilium and the plasma membrane to facilitate calcium ion release in the cell...

Introduction: Vascular endothelial growth factor (VEGF) regulates vasculogenesis in physiological and pathological states. We evaluated the role of VEGF single-nucleotide polymorphisms (SNPs) -1154 G/A, -2578 C/A, +936 C/T, and -2549 Ins/Del in chronic allograft nephropathy. Methods: Blood samples were collected before renal transplantation, and DNA was extracted. Genotyping of VEGF SNPs -1154 G/A (rs1570360), -2578 C/A (rs699947), +936 C/T (rs112005313), and -2549 Ins/Del (18bpindel) polymorphisms were carried out...

Philipp Moog, Philipp J Jost, Maike Büttner-Herold
BACKGROUND: Monoclonal gammopathy causes several kinds of renal pathology. A rare and special form is monoclonal gammopathy-induced C3 glomerulopathy (MG-C3G). Like idiopathic C3G, MG-C3G frequently leads to end-stage renal disease. MG-C3G frequently recurs after renal transplantation, leading to graft failure in most of the patients. While there is some evidence for successful treatment of recurrent idiopathic C3 glomerulopathy with eculizumab after renal transplantation, nothing is known about its efficacy in the setting of recurrent MG-C3G...

Renal cell carcinoma (RCC) in transplanted kidneys has been reported sporadically with incidence of about 0.5%. There are currently no standard guidelines on the management of allograft RCC in renal transplant recipients. Our objective was to study effectiveness of nephron-sparing surgery (NSS) for allograft RCC. We performed a retrospective analysis of patients with RCC in renal allografts managed with NSS in our institution from January 2000 to December 2015. Patient demographics, interval between transplant and RCC diagnosis, operative parameters, perioperative complications, final pathology, and renal function were evaluated...

The prognosis of patients with allograft IgA nephropathy (IgAN) requires further investigation. We performed a bi-center retrospective cohort study on kidney transplant recipients diagnosed with IgAN in allograft biopsy. Recipients without allograft IgAN but with known IgAN before transplantation were included as the control group. We investigated the associations between clinicopathological characteristics, including allograft crescents, and the risk of death-censored graft failure. In total, 1,256 IgAN patients in both pre- and post-transplant stages were included...

INTRODUCTION: Renal autotransplantation (RA) is a safe and effective procedure to reconstruct the urinary tract which first successful surgery was performed by Hardy in 1963. The main indications reported for performing RA generally includes renovascular disease, ureteral pathologies and neoplastic disease. RA may be also useful as the last recourse in preventing kidney loss in highly selected patients, especially when conventional methods have failed. METHODS: The authors pretend to describe four total different situations where the RA was the key solution for the pathology initially presented...

Ischemia-reperfusion (I-R) injury is a serious pathology that is often encountered with thrombotic events, during surgery when blood vessels are cross-clamped, and in organs for transplantation. Increased oxidative stress is the main pathology in I-R injury, as assessed in studies on the heart, kidney, and brain with little data available on gastric I-R (GI-R). Liraglutide is a GLP-1receptor agonist that has insulinotropic and weight reducing actions, and melatonin that has much studied as a chronotropic hormone; have also studied as being antioxidative stress agents...

Klotho, which was originally identified as an anti-aging gene, forms a complex with fibroblast growth factor 23 (FGF23) receptor in kidney, with subsequent signaling that regulates mineral metabolism. Other biological activities of Klotho including anti-aging effects such as protection from various cellular stress have been shown, however, the precise mechanism of these effects of Klotho gene in the healthy human kidney is not well understood. In this study, we examined the relationships of Klotho and anti-oxidative stress gene expression levels in zero-hour biopsy specimens from 44 donors in kidney transplantation and verified them in animal models whose Klotho gene expression levels were varied...

BACKGROUND: Paraganglioma (extra-adrenal pheochromocytoma) of the bladder is a very rare disease, accounting for 0.06% of all bladder tumors. Optimal management of bladder paraganglioma before kidney transplantation is unknown. We report a case of partial cystectomy for urinary bladder paraganglioma before living kidney transplantation. CASE PRESENTATION: A 59-year-old man with a 27-year history of hemodialysis was referred to our department for further examination of a bladder tumor detected during pre-transplantation testing...

Treatment effectiveness for kidney disease is limited by lack of accuracy, sensitivity, specificity of diagnostic, prognostic, and therapeutic biomarkers. The gold standard test renal biopsy along with serum creatinine and proteinuria is often necessary to establish a diagnosis, particularly in glomerular disease. Proteomics has become a powerful tool for novel biomarker discovery in kidney disease. Novel proteomics offer earlier and more accurate diagnosis of renal pathology than possible with traditional biomarkers such as serum creatinine and urine protein...

BACKGROUND: Donor-specific anti-human leukocyte antigen (HLA) antibodies (DSA) can be preformed or de novo (dn). Strategies to manage preformed DSA are well described, but data on the management and outcomes of dnDSA are lacking. METHODS: We performed a retrospective analysis of data from a single centre of the management and outcomes of 22 patients in whom a dnDSA was identified with contemporary and follow up biopsies. RESULTS: Evolution from baseline to follow up revealed a statistically significant loss of kidney function (estimated glomerular filtration rate: 45...

Focal segmental glomerulosclerosis (FSGS) is a histologic lesion resulting from a variety of pathogenic processes that cause injury to the podocytes. Recently, mutations in more than 50 genes expressed in podocyte or glomerular basement membrane were identified as causing genetic forms of FSGS, the majority of which are characterized by onset in childhood. The prevalence of adult-onset genetic FSGS is likely to be underestimated and its clinical and histological features have not been clearly described. A small number of studies of adult-onset genetic FSGS showed that there is heterogeneity in clinical and histological findings, with a presentation ranging from sub-nephrotic proteinuria to full nephrotic syndrome...

BACKGROUND: Post-transplant lymphoproliferative disorder (PTLD) is a rare condition occurring after organ transplantation. PTLD comprises four subtypes, of which Hodgkin lymphoma (HL)-type and HL-like type (currently included in polymorphic type) account for only about 1%-3% of cases. Primary central nervous system PTLD is also rare, and most cases are Epstein-Barr virus-positive, B-cell PTLD, while no case of HL-like PTLD has yet been documented. CASE DESCRIPTION: We present a 43-year-old woman who underwent kidney transplantation for IgA nephropathy 14 years previously, and who presented to our Emergency Department with a chief complaint of seizure...
