Purpose Of Review: We review the growing clinical evidence that metabolic acidosis mediates chronic kidney disease (CKD) progression and that treatment to increase the associated low serum bicarbonate (HCO3) in CKD is disease-modifying.
Recent Findings: Seven prospective studies of patients with wide ranges of estimated glomerular filtration rates (eGFRs) and serum HCO3 examined the effect on CKD of increasing serum HCO3 using dietary acid reduction with either oral alkali (sodium bicarbonate or sodium citrate), a vegetarian diet very low in acid-producing protein (0.3 g/kg/day) supplemented with ketoanalogues or added base-producing fruits and vegetables.

Purpose Of Review: We will summarize recent epidemiological observations on the risk for overt diabetic kidney disease (DKD) in nonproteinuric patients, will focus on novel studies based on a proteomic biomarker of DKD and will discuss the possibility of preventing the progression of DKD in nonproteinuric patients by sodium glucose transporter 2 (SGLT2) inhibitors.
Recent Findings: Although less frequently than in type 2 diabetes, DKD may develop also in nonproteinuric type 1 diabetes. However, the progression rate to kidney failure in nonproteinuric diabetic people is much lower than in proteinuric ones. Read More

Purpose Of Review: Calcium phosphate (CaP) stones represent an increasingly encountered form of recurrent nephrolithiasis, but current prophylactic medical regimens are suboptimal. Although hypocitraturia is a well-described risk factor for CaP stones, strategies that enhance citrate excretion have not consistently been effective at reducing CaP saturation and stone recurrence. This review summarizes the role of citrate therapy in CaP nephrolithiasis. Read More

Purpose Of Review: The hegemony of gadolinium-based contrast agent-induced adverse events stretches beyond those who have renal impairment. 'Nephrogenic' systemic fibrosis is a misnomer: gadolinium-based contrast agents are the known trigger for the disease; kidney impairment is a risk factor. Impaired (true) glomerular filtration may be one catalyst for gadolinium-based contrast agent-induced adverse events, but it is increasingly evident that the same cluster of symptoms occurs in patients with normal renal function.

Purpose Of Review: To summarize evidence supporting that microorganisms colonizing our gastrointestinal tract, collectively known as the gut microbiota, are implicated in the development and maintenance of hypertension in experimental models.
Recent Findings: The use of gnotobiotic (germ-free) mice has been essential for advancement in this area: they develop higher blood pressure (BP) if they receive faecal transplants from hypertensive patients compared to normotensive donors, and germ-free mice have a blunted response to angiotensin II. Experimental hypertension is consistently accompanied by changes in the composition of the gut microbiota. Read More

Purpose Of Review: This review summarizes the most recent and relevant findings in the search for novel biomarkers for the most common renal diseases.
Recent Findings: Unprecedented, fast-paced technical advances in biomedical research have offered an opportunity to identify novel and more specific renal biomarkers in several clinical settings. However, despite the huge efforts made, the molecules identified so far have generally failed to provide relevant information beyond what has already been generated by established biomarkers, such as serum creatinine and proteinuria, whereas the complexity and costs of these technology platforms hamper their widespread implementation.

Purpose Of Review: Strong epidemiological and pathologic evidence associates NSAIDs with kidney disease, both acute and chronic. Hence, the usage of NSAIDs has decreased in patients with, or at risk for, chronic kidney disease (CKD). Coupled with this has been a rise in use of opioids and other non-NSAID alternatives, which do come with significant, and underrecognized, risk of nonrenal adverse events. Read More

Purpose Of Review: Traditionally, nephrolithiasis was considered a relative contraindication to kidney donation because of a risk of recurrent stones in donors and adverse stone-related outcomes in recipients. However, the scarcity of organs has driven the transplant community to re-examine and broaden selection criteria for living donors with stones. In this review, we summarize and contrast the guidelines published by various prominent national and international societies on this topic. Read More

Purpose Of Review: Despite major advances in since the discovery of the phospholipase A2 receptor (PLA2R) as the major autoantigen on podocytes in primary membranous nephropathy, there are still several unanswered questions as highlighted here.
Recent Findings: A substantial body of literature, included in more than 680 articles since 2009, has documented genetic susceptibility to primary membranous nephropathy involving PLA2R1 and class II MHC alleles, the clinical value of anti-PLA2R assays, the significance of epitope spreading of the anti-PLA2R response, discovery of thrombospondin type I domain-containing 7A (THSD7A) as a minor antigen in primary membranous nephropathy, and the ability to transfer disease into mice by infusion of anti-THSD7A sera. However, the normal physiology and pathophysiology of PLA2R and THSD7A in podocytes is still unknown and the genetic influence on disease susceptibility is unexplained. Read More

Purpose Of Review: Elevated circulating levels of growth hormone (GH) and/or increased expression of the GH receptor in the kidney are associated with the development of nephropathy in type1 diabetes and acromegaly. Conditions of GH excess are characterized by hyperfiltration, glomerular hypertrophy, glomerulosclerosis and albuminuria, whereas states of decreased GH secretion or action are protected against glomerulopathy. The direct role of GH's action on glomerular cells, particularly podocytes, has been the focus of recent studies. Read More

Purpose Of Review: Chronic kidney disease (CKD) remains a serious diabetic complication despite the use of widely employed interventions such as angiotensin-converting enzyme inhibitors and glucose-lowering treatments. Accumulation of methylglyoxal, a highly reactive glucose metabolite and a major precursor in the formation of advanced glycation end products, may link the hemodynamic, inflammatory, metabolic, and structural changes that drive diabetic CKD. Therefore, methylglyoxal may serve as a potential therapeutic target to prevent diabetic CKD. Read More

Purpose Of Review: There is increasing evidence that extended-hours regimens are associated with improved outcomes for patients on maintenance hemodialysis programs. Home hemodialysis programs are a well established way for patients to benefit from extended-hours dialysis overnight; however, there are significant barriers to home hemodialysis, which means that for many this is not an option. In center, nocturnal hemodialysis is an increasingly recognized way of offering extended-hours treatment to patients unable to undertake home-based programs and is an underutilized modality for such patients to gain from the physiological benefits of extended-hours dialysis regimens.

Purpose Of Review: Due to the organ shortage, which prevents over 90 000 individuals in the United States from receiving life-saving transplants, the transplant community has begun to critically reevaluate whether organ sources that were previously considered too risky provide a survival benefit to waitlist candidates.
Recent Findings: Organs that many providers were previously unwilling to use for transplantation, including kidneys with a high Kidney Donor Profile Index or from increased risk donors who have risk factors for window period hepatitis C virus (HCV) and HIV infection, have been shown to provide a survival benefit to transplant waitlist candidates compared with remaining on dialysis. The development of direct-acting antivirals to cure HCV infection has enabled prospective trials on the transplantation of organs from HCV-infected donors into HCV-negative recipients, with promising preliminary results.

Purpose Of Review: To assess the use, access to and outcomes of hemodialysis and peritoneal dialysis in low-resource settings.
Recent Findings: Hemodialysis tends to predominate because of costs and logistics, however services tend to be located in larger cities, often paid for out of pocket. Outcomes of dialysis-requiring acute kidney injury and end-stage kidney disease may be similar with hemodialysis and peritoneal dialysis, and therefore choice of therapy is dominated by availability, accessibility and patient or physician choice.

Purpose Of Review: There is increasing evidence that extended-hours regimens are associated with improved outcomes for patients on maintenance haemodialysis programmes. Home haemodialysis programmes are a well established way for patients to benefit from extended-hours dialysis overnight; however, there are significant barriers to home haemodialysis, which means that for many this is not an option. In centre, nocturnal haemodialysis is an increasingly recognized way of offering extended-hours treatment to patients unable to undertake home-based programmes and is an underutilized modality for such patients to gain from the physiological benefits of extended-hours dialysis regimens.

Purpose Of Review: In the last decade many attempts have been made to reduce the high residual risk of end-stage kidney disease and cardiovascular disease in patients with diabetic kidney disease by targeting a variety of risk markers. Subsequent analyses revealed that the variation in individual drug response to the tested interventions partly explains why these trials did not result in additional kidney or cardiovascular protection. This review summarizes recent insights regarding individual variation in drug response. Read More

Purpose Of Review: The review describes studies investigating the role of microRNAs in the signaling pathway of the mineralocorticoid hormone, aldosterone.
Recent Findings: Emerging evidence indicates that aldosterone alters the expression of microRNAs in target tissues thereby modulating the expression of key regulatory proteins.
Summary: The mineralocorticoid hormone aldosterone is released by the adrenal glands in a homeostatic mechanism to regulate blood volume. Read More

Purpose Of Review: Current clinical pathological classifications of glomerular diseases are inadequate at predicting patient disease progression or response to therapy. With the advent of precision medicine and its successes in oncology, it is important to understand if similar approaches in glomerular diseases can improve patient management. The purpose of this review is to summarize approaches to obtain comprehensive molecular profiles from human biopsies and utilize them to define the pathophysiology of glomerular failure. Read More

Purpose Of Review: Small-molecule inhibitors of prolyl hydroxylase domain enzymes (PHD inhibitors) are novel renal anemia therapies that increase endogenous erythropoietin (EPO) production by stabilizing hypoxia-inducible factor (HIF). This review summarizes recent findings and future perspectives of PHD inhibitors (HIF stabilizers) in chronic kidney disease (CKD)-associated anemia.
Recent Findings: Clinical trials have demonstrated that HIF stabilizers effectively increase hemoglobin levels of both nondialysis and dialysis CKD patients without causing serious adverse effects. Read More

Purpose Of Review: To summarize the findings of recent trials and meta-analyses designed to determine whether bioimpedance spectroscopy adds value to the clinical assessment of fluid status in dialysis patients so as to achieve a normally hydrated weight and put these in a contemporary context.
Recent Findings: Eight trials (published 2010-2018) and two meta-analyses (2017) are reviewed. Both haemodialysis and peritoneal dialysis modalities are represented. Read More

Purpose Of Review: Chronic kidney disease is an increasing health burden. Estimating equations using serum concentrations of creatinine and cystatin C facilitate the assessment of kidney function as reflected in estimated glomerular filtration rate (eGFR). Reduced eGFR is associated with increased risk for numerous adverse outcomes and is an important aspect in many clinical situations. Read More

Purpose Of Review: Non-valvular atrial fibrillation is common in patients with severe chronic kidney disease (CKD) and historically patients have been treated with vitamin K antagonists (VKA). However, these agents have questionable efficacy and are associated with increased bleeding risk. Non-vitamin K oral anticoagulants (NOAC) have advantages over VKA in early stage CKD. Read More

Purpose Of Review: To maintain electrolyte homeostasis, the kidneys reabsorb more than 99% of the filtered Na under physiological conditions, resulting in less than 1% of the filtered Na excreted in urine. In contrast, due to distal tubular secretion, urinary K output may exceed filtered load. This review focuses on a relatively new methodology for investigating renal epithelial transport, computational modelling and highlights recent insights regarding renal Na and K transport and O2 consumption under pathophysiological conditions, with a focus on nephrectomy.

Purpose Of Review: The epithelial sodium channel, ENaC, is responsible for Na reabsorption in several epithelia and is composed of homologous α, β, and γ subunits. Here, we will explore the differential regulation of ENaC subunits during biogenesis in the early secretory pathway.
Recent Findings: ENaC subunits are subject to numerous posttranslational modifications, including glycosylation, protease activation, disulfide bond formation, palmitoylation, and glycosylation, each of which modulate channel function. Read More
