The Tolerability and Safety Profile of Patiromer: A Novel Polymer-Based Potassium Binder for the Treatment of Hyperkalemia.
Authors: Pitt B, Garza D Abstract INTRODUCTION: Hyperkalemia (HK) occurs often among patients with chronic kidney disease (CKD) and heart failure (HF) and those treated with renin-angiotensin-aldosterone system inhibitors (RAASI). Even small deviations from normal potassium levels carry increased risk of mortality. Patiromer is approved for treatment of HK and has been shown in clinical trials to reduce serum potassium among patients with HK and comorbid conditions. Areas covered: We review pooled data from two clinical trials of patiromer in patients with CKD and HK, safety of patiromer in special populations, dru...

583 Psychometric validation and meaningful change threshold of the worst itching intensity numerical rating scale for use in hemodialysis patients with pruritus
Pruritus associated with chronic kidney disease is a distressing condition which has not been rigorously studied using validated patient-reported outcome (PRO) tools. The purpose of this study was to conduct psychometric validation of the Worst Itching Intensity Numeric Rating Scale (NRS), a single item PRO measuring the worst itching severity in the past 24 h on a 0-10-point scale, and to determine the threshold for a clinically meaningful change for this patient population. This analysis was based on data from a phase II randomized, placebo-controlled study which demonstrated the effectiveness of CR845 at reducing modera...

582 Measurement of pruritus associated with chronic kidney disease: A qualitative study of two patient-reported outcome instruments
Chronic kidney disease-associated pruritus (CKD-aP) is a debilitating chronic itching condition frequently reported in end stage renal disease patients, with no approved treatments in the United States (US). As the sensation of itching can only be assessed by patient report, reliable, valid and sensitive patient-reported outcomes (PROs) are required to demonstrate treatment benefits in studies of therapies under development for treatment of pruritus in hemodialysis (HD) patients. The purpose of this study was to conduct qualitative interviews in HD patients to evaluate the content validity of two existing PRO instruments, ...

1089 Antipruritic effect of the novel kappa opioid receptor agonist CR845
Patients with chronic kidney disease are commonly afflicted by pruritus, a condition with no treatment approved in the USA. The etiology of this condition is likely multifactorial, including systemic inflammation and deficiency in the endogenous kappa opioid system. CR845 is a novel and full kappa opioid receptor agonist with no off-target activities, including mu- or delta-opioid receptors. In addition to its unique receptor profile, the peptidic structure of CR845 restricts its entry into the central nervous system. (Source: Journal of Investigative Dermatology)

Patients with rheumatoid arthritis have a higher prevalence of chronic kidney disease than the general population. This is attributed to nephrotoxic drugs and systemic inflammation. Biologic agents have revolutionized the treatment of rheumatoid arthritis. Sumida and colleagues retrospectively examined a large rheumatoid arthritis cohort to determine whether treatment with biologics has improved kidney outcomes. Using propensity matched patients, the incidence of chronic kidney disease and change in estimated glomerular filtration rate was compared in 4000 patients treated with a biologic agent to 4000 patients who were no...

Clinical relevance and future perspective of fractures in patients with chronic kidney disease
We read with great interest the article by Pimentel et al.1 on diagnosis, treatment, and prevention of fractures in patients with chronic kidney disease (CKD). We support the message of the clinical relevance of fracture events in CKD, and we would like to add further comments on the issue, such as to stress the need to better study the likely underes timated prevalence of vertebral fractures in CKD. To do so, a systematic population-based screening with spine plain films and morphometric studies of vertebral deformity2 is needed. (Source: Kidney International)

We thank Dr. Labriola and Dr. Jadoul for their comments.1 We fully agree with the relevance of falls as a major risk factor of fracture in such patients.2 Falls were mentioned and included in Figure 12 as an important determinant of fractures. However, this issue was not extensively discussed because of few relevant data available in chronic kidney disease (CKD) patients. CKD patients, including those treated by dialysis, may have a high propensity for falls. Several factors are probably invo lved, including accelerated aging with deleterious consequences such as impaired cognitive function, neurological disorders, v...

Tumoral masses in failed kidneys
A 44-year-old male patient presented with recurrent urinary tract infections (urine cultures negative) for 2 years. He was diagnosed as having a urethral stricture, and he underwent dilatations. However, his renal functions deteriorated, and he developed chronic kidney disease (CKD) requiring dialysis and transplantation. Pretransplant workup revealed 4 –5 leukocytes on urine examination, proteinuria (0.2 g/d), and a serum creatinine level of 6.7 mg/dl. Magnetic resonance imaging of his kidneys showed multifocal hyperintense lesions in both. (Source: Kidney International)

TAK1 mediates apoptosis via p38 involve in ischemia-induced renal fibrosis.
Authors: Zhou J, Zhong J, Huang Z, Liao M, Lin S, Chen J, Chen H Abstract Renal fibrosis is a common and characteristic symptom of chronic kidney disease (CKD). However, the molecular mechanisms of renal fibrosis remain elusive. Ischemia injury, as a major cause of AKI, deserves more attention in order to improve the knowledge of AKI-induced fibrosis. Transforming growth factor-β (TGF-β)-activated kinase 1 (TAK1) interacts directly with TGF-β, which play a critical role in the progression of fibrosis. Therefore, the present study aimed to investigate the role of TAK1 in the pathogenesis of ischemia-i...

Whole-body iron transport and metabolism: Mechanistic, multi-scale model to improve treatment of anemia in chronic kidney disease
by Joydeep Sarkar, Alka A. Potdar, Gerald M. Saidel Iron plays vital roles in the human body including enzymatic processes, oxygen-transport via hemoglobin and immune response. Iron metabolism is characterized by ~95% recycling and minor replenishment through diet. Anemia of chronic kidney disease (CKD) is characterized by a lack of synthesis of er ythropoietin leading to reduced red blood cell (RBC) formation and aberrant iron recycling. Treatment of CKD anemia aims to normalize RBC count and serum hemoglobin. Clinically, the various fluxes of iron transport and accumulation are not measured so that changes during diseas...

Renal cell carcinoma (RCC), a malignancy whose incidence is increasing, is frequently encountered in general nephrology practice when acute and chronic kidney disease occurs in the course of disease. Importantly, when kidney disease develops in the setting of RCC, mortality is significantly increased with patients often dying of a non-cancer-related complication of kidney disease. As such, practicing nephrologists need to have a working knowledge of this cancer ’s biology, treatment, and complications. (Source: Kidney International)

In this study, we examined the role of clusterin in renal lipid accumulation in clusterin-knockout mice and NRK52e tubular epithelial cells. Clusterin deficiency increased the expression of SREBP1 and its target genes and decreased malonyl-CoA decarboxylase protein levels in the kidney. Expression of the endocytic receptor, megalin, and scavenger receptor class A was increased in clusterin-deficient mice. Functional analysis of lipid metabolism also revealed that lipid uptake and triglyceride synthesis were increased and fatty acid oxidation was reduced, leading to increased lipid accumulation in clusterin-deficient mice. ...

Renal Effects and Associated Outcomes During Angiotensin-Neprilysin Inhibition in Heart Failure
Conclusions Compared with enalapril, sacubitril/valsartan led to a slower rate of decrease in the eGFR and improved cardiovascular outcomes, even in patients with chronic kidney disease, despite causing a modest increase in UACR. Graphical abstract (Source: JACC: Heart Failure)

Improving the prognosis of patients with severely decreased glomerular filtration rate (CKD G4+): conclusions from a Kidney Disease: Improving Global Outcomes (KDIGO) Controversies Conference
Patients with severely decreased glomerular filtration rate (GFR) (i.e., chronic kidney disease [CKD] G4+) are at increased risk for kidney failure, cardiovascular disease (CVD) events (including heart failure), and death. However, little is known about the variability of outcomes and optimal therapeutic strategies, including initiation of kidney replacement therapy (KRT). Kidney Disease: Improving Global Outcomes (KDIGO) organized a Controversies Conference with an international expert group in December 2016 to address this gap in knowledge.

Different rates of progression and mortality in patients with chronic kidney disease at outpatient nephrology clinics across Europe
The incidence of renal replacement therapy varies across countries. However, little is known about the epidemiology of chronic kidney disease (CKD) outcomes. Here we describe progression and mortality risk of patients with CKD but not on renal replacement therapy at outpatient nephrology clinics across Europe using individual data from nine CKD cohorts participating in the European CKD Burden Consortium. A joint model assessed the mean change in estimated glomerular filtration rate (eGFR) and mortality risk simultaneously, thereby accounting for mortality risk when estimating eGFR decline and vice versa, while also correct...
