  • Hyperphosphatemia in chronic kidney disease exacerbates atherosclerosis
           via a mannosidases-mediated complex-type conversion of SCAP N-glycans
    • Authors: Chao Zhou; Quan He, Hua Gan, Tingting Zeng, Qiao Liu, John F. Moorhead, Zac Varghese, Nan Ouyang, Xiong Z. Ruan
      Abstract: Blood phosphate levels are linked to atherosclerotic cardiovascular disease in patients with chronic kidney disease (CKD), but the molecular mechanisms remain unclear. Emerging studies indicate an involvement of hyperphosphatemia in CKD accelerated atherogenesis through disturbed cholesterol homeostasis. Here, we investigated a potential atherogenic role of high phosphate concentrations acting through aberrant activation of sterol regulatory element-binding protein (SREBP) and cleavage-activating protein (SCAP)-SREBP2 signaling in patients with CKD, hyperphosphatemic apolipoprotein E (ApoE) knockout mice, and cultured vascular smooth muscle cells.

  • Proteinuria converts hepatic heparan sulfate to an effective proprotein
           convertase subtilisin kexin type 9 enzyme binding partner
    • Authors: Pragyi Shrestha; Saleh Yazdani, Romain R. Vivès, Rana El Masri, Wendy Dam, Bart van de Sluis, Jacob van den Born
      Abstract: Hepatic uptake of triglyceride-rich remnant lipoproteins is mediated by the low-density lipoprotein receptor, a low-density lipoprotein receptor related protein and the heparan sulfate proteoglycan, syndecan-1. Heparan sulfate proteoglycan also mediates low-density lipoprotein receptor degradation by a regulator of cholesterol homeostasis, proprotein convertase subtilisin kexin type 9 (PCSK9), thereby hampering triglyceride-rich remnant lipoproteins uptake. In this study, we investigated the effects of proteinuria on PCSK9, hepatic heparan sulfate proteoglycan and plasma triglyceride-rich remnant lipoproteins.

  • Making human collecting ducts and modelling disease in the laboratory
    • Authors: Adrian S. Woolf
      Abstract: Human pluripotent stem cells (hPSCs) are derived from early embryos (embryonic SCs) or made by regressing mature tissues (induced PSCs). Theoretically, such cells have the potential to form all tissue types. Reasons to generate kidney tissues from hPSCs include: understanding normal kidney development; modeling kidney disorders; and making kidney cells for regenerative medicine therapies.1

  • A multicenter blinded preclinical randomized controlled trial on Jak1/2
           inhibition in MRL/MpJ-Faslpr mice with proliferative lupus nephritis
           predicts low effect size.
    • Authors: Yutian Lei; Bettina Sehnert, Reinhard E. Voll, Conxita Jacobs-Cachá, Maria Jose Soler, Maria D. Sanchez-Niño, Alberto Ortiz, Roman D. Bülow, Peter Boor, Hans-Joachim Anders
      Abstract: Data reproducibility and single-center bias are concerns in preclinical research and compromise translation from animal to human. Multicenter preclinical randomized controlled trials (pRCT) may reduce the gap between experimental studies and RCT and improve the predictability of results, for example Jak1/2 inhibition in lupus nephritis. To evaluate this, we conducted the first pRCT in the kidney domain at two Spanish and two German academic sites. Eligible MRL/MpJ-Faslpr mice (female, age13-14 weeks, stress scores of less than two and no visible tumor or signs of infection) were equally randomized to either oral treatment with the Jak1/2 inhibitor baricitinib or vehicle for four weeks.

  • The time of onset of intradialytic hypotension during a hemodialysis
           session associates with clinical parameters and mortality.
    • Authors: David F. Keane; Jochen G. Raimann, Hanjie Zhang, Joanna Willetts, M.S. Stephan Thijssen, Peter Kotanko
      Abstract: Intradialytic hypotension (IDH) is a common complication of hemodialysis, but there is no data about the time of onset during treatment. Here we describe the incidence of IDH throughout hemodialysis and associations of time of hypotension with clinical parameters and survival by analyzing data from 21 dialysis clinics in the United States to include 785682 treatments from 4348 patients. IDH was defined as a systolic blood pressure of 90 mmHg or under while IDH incidence was calculated in 30-minute intervals throughout the hemodialysis session.

      Abstract: The COVID-19 pandemic is causing extreme stress to many health systems and an ever-mounting death toll. Out of the darkness of the last 14 months comes a beacon of hope in the form of multiple SARS-Cov-2 vaccines. To best utilize this precious resource, we must efficiently deploy vaccination to high-risk groups.

  • Glomerular filtrate affects the dynamics of podocyte detachment in a model
           of diffuse toxic podocytopathy
    • Authors: Nobuyuki Saga; Kazuo Sakamoto, Taiji Matsusaka, Michio Nagata
      Abstract: Podocyte injury and subsequent detachment are hallmarks of progressive glomerulosclerosis. In addition to cell injury, unknown mechanical forces on the injured podocyte may promote detachment. To identify the nature of these mechanical forces, we studied the dynamics of podocyte detachment using sequential ultrastructural geometry analysis by transmission electron microscopy in NEP25, a mouse model of podocytopathy induced by anti-Tac(Fv)-PE38 (LMB2), a fusion protein attached to Pseudomonas exotoxin A, targeting CD25 on podocytes.

  • AI Applications in Renal Pathology
    • Authors: Yuankai Huo; Ruining Deng, Quan Liu, Agnes B. Fogo, Haichun Yang
      Abstract: The explosive growth of artificial intelligence (AI) technologies, especially deep learning methods, has been translated at revolutionary speed to efforts in AI-assisted healthcare. New applications of AI to renal pathology have recently become available, driven by the successful AI deployments in digital pathology. However, synergetic developments of renal pathology and AI require close interdisciplinary collaborations between computer scientists and renal pathologists. Computer scientists should understand that not every AI innovation is translatable to renal pathology, while renal pathologists should capture high-level principles of the relevant AI technologies.

    • Authors: Robert Geraghty; Eric Olinger, John A. Sayer
      Abstract: Technological advances in next-generation DNA sequencing now allow fast and cost-effective sequencing of the ‘exome’, defined as all the exons in the genome. Such is the rapidity and accessibility of this technique that whole exome sequencing (WES) is becoming a first-line diagnostic tool for the investigation of many diseases, including cancers, metabolic disorders, and childhood neurodevelopmental disorders.

  • Uromodulin fights UTI with sugars
    • Authors: Andrew Beenken; Qais Al-Awqati
      Abstract: Modification of host receptor proteins with sugars, or glycosylation, is essential for the binding of many pathogens. For instance, Group B streptococcus, Helicobacter pylori, and uropathogenic Type 1 fimbriated Escherichia coli (UPEC), among others, all bind to sugars present on the membrane proteins of epithelial cells. In a recent study published in Science, Weiss et al. have shown that a specific glycosylation on uromodulin is required for it to bind UPEC and prevent colonization of bladder epithelia.

  • High rates of long-term renal recovery in survivors of COVID-19-associated
           acute kidney injury requiring kidney replacement therapy
    • Authors: H. Stockmann; J.-H.B. Hardenberg, A. Aigner, C. Hinze, I. Gotthardt, B. Stier, K.-U. Eckardt, K.M. Schmidt-Ott, P. Enghard
      Abstract: While acute kidney injury requiring kidney replacement therapy (AKI-KRT) is an important and severe complication in COVID-19 patients, data on its long-term outcomes are currently limited. Previous studies reported that 65-70% of patients with AKI-KRT had recovered from dialysis dependency at the time of hospital discharge.1,2 However, long-term renal outcomes are unknown, since post-hospital follow-up after COVID-19-associated AKI in previous studies was limited to short observational periods.1,3 We retrospectively analyzed renal outcomes in 74 hospitalized COVID-19 patients with AKI-KRT in a large tertiary care center in Berlin, Germany, between March and June 2020.

  • Best Practices for Correctly Identifying Coronavirus by Transmission
           Electron Microscopy
    • Authors: Hannah A. Bullock; Cynthia S. Goldsmith, Sara E. Miller
      Abstract: To summarize, intracellular coronaviruses are 60 to 140-nm round-to-ovoid particles, with dark 6 to 12-nm dots inside and will be contained inside a vacuole; spikes (if visible) will touch the vacuolar contents, not the cell cytosol, and will not be as prominent as those on clathrin-coated vesicles. Extracellular virus particles, released through the plasma membrane by exocytosis, will cling to the cell surface, and may be more likely to show surface projections, and the spikes will face the extracellular space. Thus, the ultrastructural findings in tissue described in many of the published articles does not confirm the presence of coronavirus directly in tissue, and, when in doubt, investigators should consult an ultrastructural virologist or one of the virology authors listed.6,29-37,39-45,47-49

  • Non-oxidized parathyroid hormone (PTH) measured by current method is not
           superior to total PTH in assessing bone turnover in chronic kidney
    • Authors: Stan R. Ursem; Annemieke C. Heijboer, Patrick C. D’Haese, Geert J. Behets, Etienne Cavalier, Marc G. Vervloet, Pieter Evenepoel
      Abstract: Parathyroid hormone (PTH) is a key regulator of bone turnover but can be oxidized in vivo, which impairs biological activity. Variable PTH oxidation may account for the rather poor correlation of PTH with indices of bone turnover in chronic kidney disease. Here, we tested whether non-oxidized PTH is superior to total PTH as a marker of bone turnover in 31 patients with kidney failure included from an ongoing prospective observational bone biopsy study and selected to cover the whole spectrum of bone turnover.

  • Differential expression of microRNA miR-150-5p in IgA nephropathy as a
           potential mediator and marker of disease progression.

      Abstract: Understanding why certain patients with IgA nephropathy progress to kidney failure while others maintain normal kidney function remains a major unanswered question. To help answer this, we performed miRnome profiling by next generation sequencing of kidney biopsies in order to identify microRNAs specifically associated with the risk of IgA nephropathy progression. Following sequencing and validation in independent cohorts, four microRNAs (-150-5p, -155-5p, -146b-5p, -135a-5p) were found to be differentially expressed in IgA nephropathy progressors compared to non-progressors, and patients with thin membrane nephropathy, lupus nephritis and membranous nephropathy, and correlated with estimated glomerular filtration rate, proteinuria, and the Oxford MEST-C scores (five histological features that are independent predictors of clinical outcome).

Fed the oxalate precursor, hydroxyproline, every rat in this model develops calcium oxalate stones. Using this rat model, we tested whether chlorthalidone and potassium citrate combined would reduce calcium oxalate stone formation and improve bone quality more than either agent alone. These rats (113 generation) were fed a normal calcium and phosphorus diet with hydroxyproline and divided into four groups: diets plus potassium chloride as control, potassium citrate, chlorthalidone plus potassium chloride, or potassium citrate plus chlorthalidone.

  • Rho-GTPase Activating Protein myosin MYO9A identified as a novel candidate
           gene for monogenic focal segmental glomerulosclerosis.
    • Authors: Qi Li; Ashima Gulati, Mathieu Lemaire, Timothy Nottoli, Allen Bale, Alda Tufro
      Abstract: Focal segmental glomerulosclerosis (FSGS) is a podocytopathy leading to kidney failure, whose molecular cause frequently remains unresolved. Here, we describe a rare MYO9A loss of function nonsense heterozygous mutation (p.Arg701*) as a possible contributor to disease in a sibling pair with familial FSGS/proteinuria. MYO9A variants of uncertain significance were identified by whole exome sequencing in a cohort of 94 biopsy proven patients with FSGS. MYO9A is an unconventional myosin with a Rho-GAP domain that controls epithelial cell junction assembly, crosslinks and bundles actin and deactivates the small GTPase protein encoded by the RHOA gene.

  • Innate lymphoid cells in kidney diseases
    • Authors: Ruifeng Wang; Yiping Wang, David C.H. Harris, Qi Cao
      Abstract: It is well known that innate immune cells, including dendritic cells, macrophages and natural killer cells contribute to pathogenesis and protection in various kidney diseases. The understanding of innate immunity has been advanced recently by the discovery of a new group of innate lymphoid cells (ILCs) including ILC1, ILC2, and ILC3. ILCs lack adaptive antigen receptors, yet can be triggered by various pathogens and rapidly provide an abundant source of immunomodulatory cytokines to exert immediate immune reactions and direct subsequent innate and adaptive immune responses.

      Abstract: Immune checkpoint inhibitors (ICIs) are widely used for various malignancies. However, their safety and efficacy in patients with a kidney transplant have not been defined. To delineate this, we conducted a multicenter retrospective study of 69 patients with a kidney transplant receiving ICIs between January 2010 and May 2020. For safety, we assessed the incidence, timing, and risk factors of acute graft rejection. For efficacy, objective response rate and overall survival were assessed in cutaneous squamous cell carcinoma and melanoma, the most common cancers in our cohort, and compared with stage-matched 23 patients with squamous cell carcinoma and 14 with melanoma with a kidney transplant not receiving ICIs.

      Abstract: BK polyomavirus-associated nephropathy is a common complication after kidney transplantation leading to reduced graft function or loss. The molecular pathogenesis of BK polyomavirus-induced nephropathy is not well understood. A recent study had described a protective effect of the activating natural killer cell receptor KIR3DS1 in BK polyomavirus-associated nephropathy, suggesting a role of NK cells in modulating disease progression. Using an in vitro cell culture model of human BK polyomavirus infection and kidney biopsy samples from patients with BK polyomavirus-associated nephropathy, we observed significantly increased surface expression of the ligand for KIR3DS1, HLA-F, on BK polyomavirus-infected kidney tubular cells.

      Abstract: Chronic kidney disease (CKD) promotes development of cardiac abnormalities and is highly prevalent in patients with heart failure, particularly in those with preserved ejection fraction. CKD is associated with endothelial dysfunction, however, whether CKD can induce impairment of endothelium-to-cardiomyocyte crosstalk leading to impairment of cardiomyocyte function is not known. The sodium-glucose co-transporter 2 inhibitor, empagliflozin, reduced cardiovascular events in diabetic patients with or without CKD, suggesting its potential as a new treatment for heart failure with preserved ejection fraction.

      Abstract: With the widespread use combination antiretroviral therapy, there has been a dramatic decrease in HIV-associated nephropathy. However, although the patients living with HIV have low or undetectable viral load, the prevalence of chronic kidney disease (CKD) in this population remains high. Additionally, improved survival is associated with aging-related comorbidities such as diabetes and cardiovascular disease. A faster progression of CKD is associated with concurrent HIV infection and diabetes than with HIV infection or diabetes alone.

      Abstract: Endothelial dysfunction, one of many causes of arterial changes in end-stage kidney disease (kidney failure). is a likely link between early vascular aging and the risk of thrombosis or bleeding in this condition To evaluate this, we compared links between arterial stiffness and endothelial/coagulation factors in 55 patients receiving hemodialysis therapy and 57 age-/sex-matched control individuals. Arterial stiffness was assessed from carotid-femoral pulse wave velocity, and coagulation status from the endogenous thrombin generating potential.

      Abstract: With a rising demand for kidney transplantation, reliable pre-transplant assessment of organ quality becomes top priority. In clinical practice, physicians are regularly in doubt whether suboptimal kidney offers from older donors should be accepted. Here, we externally validate existing prediction models in a European population of older deceased donors, and subsequently developed and externally validated an adverse outcome prediction tool. Recipients of kidney grafts from deceased donors 50 years of age and older were included from the Netherlands Organ Transplant Registry (NOTR) and United States organ transplant registry from 2006-2018.

      Abstract: Proteinuria is a well-established marker and predictor of kidney disease. The receptors megalin and cubilin reabsorb filtered proteins and thereby proteinuria is avoided. It is unknown if all segments of the proximal tubule are involved in clearing the filtrate or if there exists a reserve capacity in case of increased glomerular protein filtration. To determine this, we performed serial sectioning of rat kidney and used stereology to quantify the endolysosomal system of the three segments of cortical and juxtamedullary nephrons by electron microscopy.

      Abstract: Aminopeptidase A is one of the most potent enzymes within the renin-angiotensin system in terms of angiotensin II degradation. Here, we examined whether there is a kidney phenotype and any compensatory changes in other renin angiotensin system enzymes involved in the metabolism of angiotensin II associated with aminopeptidase A deficiency. Kidneys harvested from aminopeptidase A knockout mice were examined by light and electron microscopy, immunohistochemistry and immunofluorescence. Kidney angiotensin II levels and the ability of renin angiotensin system enzymes in the glomerulus to degrade angiotensin II ex vivo, their activities, protein and mRNA levels in kidney lysates were evaluated.

      Abstract: Canagliflozin slows the progression of chronic kidney disease in patients with type 2 diabetes and induces a reversible acute drop in estimated glomerular filtration rate (eGFR), believed to be a hemodynamic effect. Predictors of the initial drop and its association with long-term eGFR trajectories and safety outcomes are unknown. To assess this, we performed a post-hoc analysis of 4289 participants in the CREDENCE trial with type 2 diabetes and chronic kidney disease equally split into treatment and placebo groups who had eGFR measured at both baseline and week three.

      Abstract: Kidney tubular dysfunction contributes to acute kidney injury and to the transition to chronic kidney disease. Although tubular mitochondria have been implicated in the pathophysiology of kidney failure, the mechanisms are not yet clear. Here, we demonstrated that ischemia-reperfusion injury induced acute translocation and activation of mitochondrial protein kinase B (also known as AKT1) in the kidney tubules. We hypothesized that mitochondrial AKT1 signaling protects against the development of acute kidney injury and subsequent chronic kidney disease.

A single variant c.1871G>A p.Gly624Asp (G624D) in COL4A5 was predominant and accounted for 39% of X-linked Alport Syndrome in unrelated Polish families (44 of 113). To evaluate its origins, the genetic variation in a 2.79 Mb segment encompassing the COL4A5 locus on chromosome X was assessed. All G624D alleles were found on the same rare haplotype background, indicating a founder effect dating back to the 12-13th century.

      Abstract: Ravulizumab, a long-acting complement C5 inhibitor engineered from eculizumab, allows extending maintenance dosing from every 2–3 weeks to every 4–8 weeks depending on bodyweight. Here, we evaluated the efficacy and safety of ravulizumab in complement inhibitor-naïve children (under 18 years) with atypical hemolytic uremic syndrome. In this phase III, single-arm trial, ravulizumab was administered every eight weeks in patients 20 kg and over, and four weeks in patients under 20 kg. The primary endpoint was a complete thrombotic microangiopathy response (normalization of platelet count and lactate dehydrogenase, and a 25% or more improvement in serum creatinine) through 26 weeks.

      Abstract: The kidney has extraordinary metabolic demands to sustain the active transport of solutes that is critical to renal filtration and clearance. Mitochondrial health is vital to meet those demands and maintain renal fitness. Decades of studies have linked poor mitochondrial health to kidney disease. Key regulators of mitochondrial health – 5-AMP-activated protein kinase (AMPK), sirtuins, and peroxisome proliferator-activated receptor γ coactivator-1alpha (PGC1α) – have all been shown to play significant roles in renal resilience against disease.

      Abstract: Cisplatin is widely used as an anti-tumor drug for the treatment of solid tumors. Unfortunately, it causes kidney toxicity as a critical side effect, limiting its use, given that no preventive drug against cisplatin-induced kidney toxicity is currently available. Here, based on a repositioning analysis of the Food and Drug Administration Adverse Events Reporting System, we found that a previously developed drug, diphenhydramine, may provide a novel treatment for cisplatin-induced kidney toxicity.

      Abstract: Very high protein intake may lead to increased intraglomerular pressure, glomerular hyperfiltration, and chronic kidney disease (CKD). For this and other reasons dietary protein restriction has long been used with the aim of slowing the progression of CKD. In addition to the quantity of ingested protein, the quality of protein is also of importance for body growth, composition, and function. This also holds true for microbiota growth, composition, and function in the intestine. Generally speaking, nutrient intake is known to modify the relative abundance and the diversity of intestinal microbes, and dietary changes can induce alterations in gut microbial metabolite production.

      Abstract: Although IgA nephropathy (IgAN) is a common cause of glomerulonephritis in children, the absence of a method to predict disease progression limits personalized risk-based treatment decisions. The adult International IgAN Prediction Tool comprises two validated Cox survival models that predict a 50% decline in estimated glomerular filtration rate (eGFR) or end stage kidney disease (ESKD) using clinical risk factors and Oxford MEST histology scores. Here, we updated the Prediction Tool for use in children using a multiethnic international cohort of 1,060 children with IgAN followed into adulthood.

      Abstract: Emerging evidence has shown that mitochondrial dysfunction is closely related to the pathogenesis of podocytopathy, but the molecular mechanisms mediating mitochondrial dysfunction in podocytes remain unclear. Lon protease 1 is an important soluble protease localized in the mitochondrial matrix, although its exact role in podocyte injury has yet to be determined. Here we investigated the specific role of this protease in podocyte in glomerular injury and the progression of podocytopathy using podocyte-specific Lon protease 1 knockout mice, murine podocytes in culture and kidney biopsy samples from patients with focal segmental glomerular sclerosis and minimal change disease.

We hypothesized that sequential therapy with tacrolimus and rituximab is superior to cyclical alternating treatment with corticosteroids and cyclophosphamide in inducing persistent remission in these patients. This was tested in a randomized, open-label controlled trial of 86 patients with primary membranous nephropathy and persistent nephrotic syndrome after six-months observation and assigned 43 each to receive six-month cyclical treatment with corticosteroid and cyclophosphamide or sequential treatment with tacrolimus (full-dose for six months and tapering for another three months) and rituximab (one gram at month six).

      Abstract: The CKD-EPI creatinine-based estimation equation for glomerular filtration rate (GFR) cannot be used in children, overestimates GFR in young adults, and its combination with the KDIGO recommended pediatric CKiD (Schwartz bedside) equation causes implausible increases in estimated GFR when switching from pediatric to adult care. By establishing sex-specific creatinine growth curves for children and young adults, creatinine levels of children and young adults below age 40 years were adjusted with 40 as assigned age and applied in the CKD-EPI equation.

Here, we investigated whether patients with long-term transplantation and still on immunosuppressive therapy would present such a signature of low immunological rejection risk, compared to more recently transplanted patients. Of 114 kidney transplant recipients enrolled, 38 with more than 25 years of graft survival and stable graft function under calcineurin inhibitors, were matched with two different groups of transplanted patients (10-15 and 5-7 years after transplantation).

      Abstract: The treatment of hyperphosphatemia remains challenging in patients receiving hemodialysis. This Phase 1b study assessed safety and efficacy of EOS789, a novel pan-inhibitor of phosphate transport (NaPi-2b, PiT-1, PiT-2) on intestinal phosphate absorption in patients receiving intermittent hemodialysis therapy. Two cross-over, randomized order studies of identical design (ten patients each) compared daily EOS789 50 mg to placebo with meals and daily EOS789 100 mg vs EOS789 100 mg plus 1600 mg sevelamer with meals.

      Abstract: Rapid decline of glomerular filtration rate estimated from creatinine (eGFRcrea) is associated with severe clinical endpoints. In contrast to cross-sectionally assessed eGFRcrea, the genetic basis for rapid eGFRcrea decline is largely unknown. To help define this, we meta-analyzed 42 genome-wide association studies from the Chronic Kidney Diseases Genetics Consortium and United Kingdom Biobank to identify genetic loci for rapid eGFRcrea decline. Two definitions of eGFRcrea decline were used: 3 mL/min/1.73m2/year or more (“Rapid3”; encompassing 34,874 cases, 107,090 controls) and eGFRcrea decline 25% or more and eGFRcrea under 60 mL/min/1.73m2 at follow-up among those with eGFRcrea 60 mL/min/1.73m2 or more at baseline (“CKDi25”; encompassing 19,901 cases, 175,244 controls).

    • Authors: Tiffany Caza; Samar Hassen, Michael Kuperman, Shree Sharma, Zeljko Dvanajscak, John Arthur, Rick Edmondson, Aaron Storey, Christian Herzog, Daniel Kenan, Christopher Larsen
      Abstract: Membranous lupus nephritis is a frequent cause of nephrotic syndrome in patients with systemic lupus erythematosus. It has been shown in phospholipase A2 receptor positive membranous; nephropathy that known antibodies can be detected within sera, determination of the target; autoantigen can have diagnostic significance, inform prognosis, and enable non-invasive; monitoring of disease activity. Here we utilized mass spectrometry for antigen discovery in laser; captured microdissected glomeruli from formalin-fixed paraffin embedded tissue and tissue; protein G immunoprecipitation studies to interrogate immune complexes from frozen kidney; biopsy tissue.

      Abstract: The kidney is one of the most sensitive organs to cadmium-induced toxicity, particularly in conditions of long-term oxidative stress. We hypothesized that, in kidney transplant recipients, nephrotoxic exposure to cadmium represents an overlooked hazard for optimal graft function. To test this, we performed a prospective cohort study and included 672 outpatient kidney transplant recipients with a functioning graft of beyond one year. The median plasma cadmium was 58 ng/L. During a median 4.9 years of follow-up, 78 kidney transplant recipients developed graft failure with a significantly different distribution across tertiles of plasma cadmium (13, 26, and 39 events, respectively).

      Abstract: Mice with disruption of Pkd1 in osteoblasts demonstrate reduced bone mineral density, trabecular bone volume and cortical thickness. To date, the bone phenotype in adult patients with autosomal dominant polycystic kidney disease (ADPKD) with stage I and II chronic kidney disease has not been investigated. To examine this, we characterized biochemical markers of mineral metabolism, examined bone turnover and biology, and estimated risk of fracture in patients with ADPKD. Markers of mineral metabolism were measured in 944 patients with ADPKD and other causes of kidney disease.

  • Renin-angiotensin aldosterone inhibitor use at hospital discharge among
           patients with moderate to severe acute kidney injury and its association
           with recurrent acute kidney injury and mortality.

      Abstract: Recurrent episodes of acute kidney injury (AKI) are common among AKI survivors. Renin-angiotensin aldosterone inhibitors (RAASi) are often indicated for these patients but may increase the risk for recurrent AKI. Here, we examined whether RAASi associates with a higher risk for recurrent AKI and mortality among survivors of moderate to severe AKI in a retrospective cohort of Veterans who survived Stage II or III AKI. The primary exposure was RAASi at hospital discharge and the primary endpoint was recurrent AKI within 12 months.

  • Prediction modelling - Part 2 - Using machine learning strategies to
           improve transplantation outcomes
    • Authors: Craig Peter Coorey; Ankit Sharma, Samuel Mueller, Jean Yang
      Abstract: Kidney transplant recipients and transplant physicians face important clinical questions where machine learning methods may help improve the decision-making process. This mini-review explores potential applications of machine learning methods to key stages of a kidney transplant recipient’s journey, from initial waitlisting and donor selection, to personalization of immunosuppression and prediction of post-transplantation events. Both unsupervised and supervised machine learning methods are presented, including k-means clustering, principal components analysis, k-nearest neighbors and random forests.

  • Time-dependent lymphocyte count after transplantation is associated with
           higher risk of graft failure and death.
    • Authors: Amaury Dujardin; Marine Lorent, Yohann Foucher, Christophe Legendre, Clarisse Kerleau, Sophie Brouard, Magali Giral, DIVAT consortium
      Abstract: The transplantation field requires the identification of specific risk factors associated with the level of immunosuppression. Here, our aim was to analyze the association between the number of circulating lymphocytes, monitored routinely by complete blood cell counts during outpatient visits, and patient and graft survival. In total, 2,999 kidney or combined kidney-pancreas recipients transplanted between 2000 and 2016, from two University hospitals, were enrolled. We investigated the etiological relationship between time-dependent lymphocyte count beyond one year after transplantation and patient and graft survival, viral infection and cancer risk using time-dependent multivariate Cox models.

      Abstract: We have developed an artificial neural network prediction model for end-stage kidney disease (ESKD) in patients with primary immunoglobulin A nephropathy (IgAN) using a retrospective cohort of 948 patients with IgAN. Our tool is based on a two-step procedure of a classifier model that predicts ESRD, and a regression model that predicts development of ESKD over time. The classifier model showed a performance value of 0.82 (area under the receiver operating characteristic curve) in patients with a follow-up of five years, which improved to 0.89 at the ten-year follow-up.

  • NELL1 is a target antigen in malignancy-associated membranous nephropathy
    • Authors: Tiffany Caza; Samar Hassen, Zeljko Dvanajscak, Michael Kuperman, Rick Edmondson, Christian Herzog, Aaron Storey, John Arthur, L. Nicholas Cossey, Shree Sharma, Daniel Kenan, Christopher Larsen
      Abstract: Patients with membranous nephropathy have an increased risk of malignancy compared to the general population, but the target antigen for malignancy-associated membranous nephropathy is unknown. To explore this, we utilized mass spectrometry for antigen discovery in malignancy-associated membranous nephropathy examining immune complexes eluted from frozen kidney biopsy tissue using protein G bead immunoglobulin capture. Antigen discovery was performed comparing cases of membranous nephropathy of unknown and known type.

  • Simultaneous Glomerular Filtration Rate Determination Using Inulin,
           Iohexol and 99mTc-DTPA Demonstrates the Need for Customized Measurement
    • Authors: Christine A. White; Ayub Akbari, Celine Allen, Andrew G. Day, Patrick A. Norman, David Holland, Michael A. Adams, Greg A. Knoll
      Abstract: Urinary inulin clearance is considered the gold standard of glomerular filtration rate (GFR)measurement but plasma clearance of less expensive and more accessible tracers is more commonly performed. Many plasma sampling protocols exist but little is known about their accuracy. Here, the study objectives were to compare plasma iohexol and 99mTc-DTPA GFR with varying sampling strategies to the GFR measured by urinary inulin and to identify protocols with the greatest accuracy according to clinical characteristics.
