OBJECTIVE: Patients with type 1 diabetes (T1D) with impaired renal function are at increased risk for end-stage renal disease (ESRD). Although the rate of progression varies, determinants and mechanisms of this variation are unknown. RESEARCH DESIGN AND METHODS: We examined serum metabolomic profiles associated with variation in renal function decline in participants with T1D (the Joslin Kidney Study prospective cohort). One hundred fifty-eight patients with proteinuria and chronic kidney disease stage 3 were followed for a median of 11 years to determine estimated glomerular filtration rate slopes from serial measurements of serum creatinine and to ascertain time to onset of ESRD...

Little is known about the risk factors of proteinuria in the Asian population. On the basis of the association between rice intake patterns and chronic diseases, we hypothesized that rice intake patterns are associated with proteinuria in the Asian population. Data, including data regarding rice intake frequency and dipstick urinalysis results, from the Korea National Health and Nutrition Examination Survey in 1998, 2001, 2005, and 2007 were analyzed. The study involved 19,824 participants who were older than 20 years of age...

Study has shown that stem cell–based therapies are promising strategies in the treatment of several chronic diseases, but their overall benefit in the treatment of diabetic nephropathy (DN) remains controversial. The purpose of this study is to summarize the evidence of the effect of cell-based therapy in the treatment of DN to guide future clinical trials. We searched PubMed, EmBase, and the Cochrane Library for studies from the inception of cell-based therapies up to July 2015. We included animal trials that reported the effects of cell-based therapy on kidney function, cardiovascular risk factors, and body factors...

Renal involvement is the most important cause of morbidity and mortality in systemic amyloidosis. This retrospective analysis was conducted to analyse the clinico-pathological characteristics of renal amyloidosis in a group of Sri Lankan patients undergoing renal biopsy. Renal amyloidosis was observed in 50/ 9712 (0.5%) renal biopsies. The underlying cause for amyloidosis was not known in most. Of the known causes multiple myeloma was the commonest. Nephrotic range proteinuria was the most common clinical outcome and most had grade I to III chronic kidney disease at the time of diagnosis...

Proteinuria is one of the primary risk factors for the progression of chronic kidney disease (CKD) and has been implicated in the induction of endoplasmic reticulum (ER) stress. We hypothesized that the suppression of ER stress with a low molecular weight chemical chaperone, 4-phenylbutyric acid (4-PBA), would reduce the severity of CKD and proteinuria in the Dahl salt-sensitive (SS) hypertensive rat. To induce hypertension and CKD, 12-wk-old male rats were placed on a high-salt (HS) diet for 4 wk with or without 4-PBA treatment...

The high frequency of monoclonal gammopathy in adult patients with C3 glomerulopathy (C3G) emphasizes the role of the monoclonal immunoglobulin (MIg) in the occurrence of renal disease and raises the issue of the therapeutic management. The aim of the study was to evaluate the effect of chemotherapy in a large cohort of patients with MIg-associated C3G. Fifty adult patients with MIg and biopsy-proven C3G were extracted from the French national database of C3G. We retrospectively compared renal outcomes in patients who received or not chemotherapy targeting the underlying B-cell clone...

BACKGROUND: Some studies have suggested that Helicobacter pylori (H. Pylori) infection was associated with insulin resistance and metabolic syndrome, which may increase the risk of chronic kidney disease (CKD). But there is no conclusive evidence regarding the association between H. Pylori infection and CKD. To help clarify this, we conducted the cross-sectional study to investigate the association of H. pylori infection with CKD among Chinese adults. METHODS: A total of 22,044 adults aged 48...

BACKGROUND: Proteinuria is common in patients with acute heart failure (AHF). This study investigated the relationship between proteinuria and short-term mortality among patients hospitalized for AHF at two university hospitals. METHODS: The death risk was assessed using a 30-day mortality risk score. Of the 1058 eligible patients with AHF, 583 (55.1%) exhibited proteinuria. The degree of proteinuria was positively correlated with poor AHF prognostic indicators (C-reactive protein and N-terminal pro-brain natriuretic peptide) and negatively correlated with protective indicators (basal estimated glomerular filtration rate, haemoglobin, and serum albumin)...

AIM: It was believed that neurogenic bladder (NB) might be a risk factor of chronic kidney disease (CKD). However, data are limited regarding the real incidence or risk of CKD in NB. In addition, serum creatinine (sCr), a classical marker of renal function, is not reliable in NB patients because they present muscle wasting due to disuse or denervation. The aim of the study was to estimate the prevalence of CKD in NB patients using serum Cystatin-C. Secondly, we aimed to identify the risk factors for CKD development in NB...

BACKGROUND: Renal function in patients with chronic kidney disease (CKD) may follow different trajectory profiles. The aim of this study was to evaluate and illustrate the ability of the latent class linear mixed model (LCMM) to identify clinically relevant subgroups of renal function trajectories within a multicenter hospital-based cohort of CKD patients. METHODS: We analysed data from the NephroTest cohort including 1967 patients with all-stage CKD at baseline who had glomerular filtration rate (GFR) both measured by (51)Cr-EDTA renal clearance (mGFR) and estimated by the CKD-EPI equation (eGFR); 1103 patients had at least two measurements...

BACKGROUND/AIMS: Fabry disease is a treatable cause of chronic kidney disease (CKD) characterized by a genetic deficiency of α-galactosidase A. European Renal Best Practice (ERBP) recommends screening for Fabry disease in CKD patients. However, this is based on expert opinion and there are no reports of the prevalence of Fabry disease in stage 1-5 CKD. Hence, we investigated the prevalence of Fabry disease in CKD patients not receiving renal replacement therapy. METHODS: This prospective study assessed α-galactosidase activity in dried blood spots in 313 stage 1-5 CKD patients, 167 males, between ages of 18-70 years whose etiology of CKD was unknown and were not receiving renal replacement therapy...

Inherited distal renal tubular acidosis (dRTA) is caused by impaired urinary acid excretion resulting in hyperchloremic metabolic acidosis. Although the glomerular filtration rate (GFR) is usually preserved, and hypertension and overt proteinuria are absent, it has to be considered that patients with dRTA also suffer from chronic kidney disease (CKD) with an increased risk for adverse pregnancy-related outcomes. Typical complications of dRTA include severe hypokalemia leading to cardiac arrhythmias and paralysis, nephrolithiasis and nephrocalcinosis...

INTRODUCTION: Smoking is an important risk factor not only for cardiovascular and pulmonary diseases, but also for the progression of chronic kidney disease of different etiologies. Nodular glomerulosclerosis is a renal pathology pattern, which was described in different kidney conditions, especially diabetic nephropathy. A very rare association among smoking, hypertension and nodular mesangial glomerulosclerosis has been recently described. CASE PRESENTATION: In this paper, we present the case of a non-diabetic male patient referred to our Department for advanced chronic kidney disease and nephrotic syndrome...

Cardiac fibrosis is a common finding in patients with chronic kidney disease. Here, we investigate the cardio-renal effects of theracurmin, a novel formulation of the polyphenolic compound curcumin, in a rat model of chronic kidney disease. Briefly, Sprague-Dawley rats were randomized to undergo sham or subtotal nephrectomy (SNx) surgery. At 3 weeks post surgery, SNx animals were further randomized to received theracurmin via once daily oral gavage or vehicle for 5 consecutive weeks. At 8 weeks post surgery, cardiac function was assessed via echocardiography and pressure volume loop analysis, followed by LV and renal tissue collection for analysis...

Most forms of chronic, progressive kidney disease are characterized by fibrosis whereby the prototypical prosclerotic growth factor, transforming growth factor β (TGF-β), is thought to play a pivotal role. With the recent understanding that TGF-β's canonical signaling pathway may be modified by acetylation as well as phosphorylation, we explored the role of the NAD(+)-dependent lysine deacetylase, sirtuin 1 (SIRT1) in fibrogenesis in the cell culture, animal model, and human settings. In vitro, the increase in collagen production that results from TGF-β1 stimulation was ameliorated by the allosteric modifier of Sirt1 deacetylase, SRT3025, in association with a reduction in Smad3 reporter activity...

Chronic kidney disease is a major complication of Fabry disease. Podocytes accumulate globotriaosylceramide inclusions more than other kidney cell types in Fabry patients. Podocyte injury occurs early in age, and is progressive. Since injured podocytes detach into the urine (podocyturia), we hypothesized that podocyturia would increase in Fabry patients and correlate with clinical severity of Fabry nephropathy. Urine specimens from 39 Fabry patients and 24 healthy subjects were evaluated for podocyturia. Most of the Fabry patients and many healthy subjects had podocyturia...
