BACKGROUND: Diabetic nephropathy has become the most common cause of chronic kidney disease (CKD). Despite the progress accomplished in therapy, the prevalence of renal disorders remains high. Some modifiable factors driving the increase in incidence of CKD, in diabetes and other settings, might have been overlooked. Consistent evidence supports a role for vasopressin, hydration state, and urine concentration in kidney health. SUMMARY: Plasma vasopressin is elevated in diabetes, even if metabolic control is good...

BACKGROUND: Secondary hyperparathyroidism (SHPT) is a frequent complication of renal disease and most commonly occurs in patients on haemodialysis (HD) with metabolic, vascular, endocrine, and bone complications. The aim of this study was to analyze the evolution of mineral metabolism parameters during the first 36 months of HD treatment and identify the initial factors associated with severe SHPT. METHODS: Serum parathyroid hormone (PTH), calcium and phosphate levels were measured monthly; bone-specific alkaline phosphatase (b-ALP) and beta-CrossLaps (CTX) were measured biannually...

Diabetic kidney disease is a common complication of type 1 and type 2 diabetes and is the primary cause of end-stage renal disease in developed countries. Early detection of diabetic kidney disease will facilitate early intervention aimed at reducing the rate of progression to end-stage renal disease. Diabetic kidney disease has been traditionally classified based on the presence of albuminuria. More recently estimated glomerular filtration rate has also been incorporated into the staging of diabetic kidney disease...

Nephropathic cystinosis is a rare lysosomal storage disorder. Patients present in the first year of life with renal Fanconi syndrome that evolves to progressive chronic kidney disease (CKD). Despite the multiple risk factors for bone disease, the frequency and severity of skeletal disorders in nephropathic cystinosis have not been described. We performed systematic bone and mineral evaluations of subjects with cystinosis seen at the NIH (N = 30), including history and physical examination, serum and urine biochemistries, DXA, vertebral fracture assessment, skeletal radiographs, and renal ultrasound...

BACKGROUND: The prevalence of type 2 diabetes (DM) in children is disturbingly increasing in parallel with increasing childhood obesity. Better knowledge regarding the pathophysiology of type 2 DM in children is paramount to devise an effective management plan. OBJECTIVE: Discuss the pathophysiology of type 2 DM in children and adolescents Methods and results: This is a comprehensive review of the literature on this topic. Type 2 DM in childhood is viewed as a continuum of insulin resistance (IR) which is determined by an underlying genetic predisposition, intrauterine environment, excessive food consumption, continued rapid weight gain, and poor lifestyle...

Chronic kidney disease-mineral bone disorders (CKD-MBD) exhibit abnormalities in the circulating mineral levels, vitamin D metabolism, and parathyroid function that contribute to the formation of a bone lesion. The uremic toxin, indoxyl sulfate (IS), accumulates in the blood in cases of renal failure and leads to bone loss. The bone and renal responses to the action of the parathyroid hormone (PTH) are progressively decreased in CKD in spite of increasing PTH levels, a condition commonly called PTH resistance...

Three members of the fibroblast growth factor (FGF) family, FGF19, FGF21 and FGF23, are different from the other members in two major aspects. First, they are actually not growth factors but endocrine factors that regulate various metabolic processes. Second, their physiological receptors are not FGF receptors (FGFRs) but binary complexes of FGFRs and Klotho proteins. FGF23 and FGF21 have emerged as biomarkers that start increasing in early-stage chronic kidney disease (CKD). FGF23 is a bone-derived phosphaturic hormone that binds to the αKlotho-FGFR complex expressed in renal tubules to increase phosphate excretion per nephron...

BACKGROUND: Despite optimal management of diabetic kidney disease (DKD) with intensive glycemic control and administration of agents blocking the renin-angiotensin-aldosterone-system, the residual risk for nephropathy progression to end-stage-renal-disease (ESRD) remains high. Sodium-glucose co-transporter type 2 (SGLT-2)-inhibitors represent a newly-introduced anti-diabetic drug class with pleiotropic actions extending above their glucose-lowering efficacy. Herein, we provide an overview of preclinical and clinical-trial evidence supporting a protective effect of SGLT-2 inhibitors on DKD...

In chronic kidney disease (CKD), the progressive decrease in renal function leads to disturbances of mineral metabolism that generally cause secondary hyperparathyroidism. The increase in serum parathyroid hormone is associated with reduced serum calcium and calcitriol levels and/or increased serum fibroblast growth factor-23 and phosphate levels. The resulting CKD-associated disorder of mineral and bone metabolism is associated with various other metabolic dysregulations such as acidosis, malnutrition, inflammation, and accumulation of uremic toxins...

Mitochondrial dysfunction is increasingly recognized as a critical determinant of both hereditary and acquired kidney diseases. However, it remains poorly understood how mitochondrial metabolism is regulated to support normal kidney function and how its dysregulation contributes to kidney disease. Here, we show that the nuclear receptor estrogen-related receptor gamma (ERRγ) and hepatocyte nuclear factor 1 beta (HNF1β) link renal mitochondrial and reabsorptive functions through coordinated epigenomic programs...

Over the past two years, our understanding of anti-hyperglycemic medications used to treat patients with type 2 diabetes (T2D) has fundamentally changed. Before the EMPA-REG OUTCOME trial, agents used to lower blood glucose were felt to prevent or delay the development of microvascular complications, but were not known to definitively reduce cardiovascular risk or mortality. Previous studies with then novel sodium-glucose cotransport-2 (SGLT2) inhibitors demonstrated improvements in several cardiovascular and renal risk factors, including HbA1c, blood pressure, weight, renal hyperfiltration, and albuminuria...

Renal prognostic factors of chronic kidney disease are important concerns for patients. Kidney biopsy can be used to evaluate not only the activity of the original disease but also various risk factors related to the lifestyle of patients. Considering that lifestyle-related factors, including obesity and metabolic syndrome, are crucial prognostic risk factors of kidney disease progression and all-cause mortality, evaluation of lifestyle-related prognostic factors in kidney biopsy of all kidney diseases is important...

OBJECTIVE: Introduction: Hypertension is a major reason behind morbidity, disability and mortality. Elevated blood pressure is a huge risk factor for cardio-vascular diseases. Almost 90% of hypertension patients have internal comorbidities, in particular hypothyroidism. For now, however, the specificities of the clinical course of hypertension in hypothyroid patients are understudied and the data on lipid metabolism in patients with primary hypothyroidism and hypertension are inconclusive...

Tubulointerstitial inflammatory cell infiltration and activation contribute to kidney inflammation and fibrosis. Epoxyeicosatrienoic acids (EETs), which are rapidly metabolized to dihydroxyeicosatrienoic acids by the soluble epoxide hydrolase (sEH), have multiple biological functions, including vasodilation, anti-inflammatory action, and others. Inhibition of sEH has been demonstrated to attenuate inflammation in many renal disease models. However, the relationship between sEH expression and macrophage polarization in kidney remains unknown...

BACKGROUND: Fibroblast growth factor 23 (FGF-23), an osteocyte hormone involved in the regulation of phosphate metabolism, is associated with incident and progressive chronic kidney disease. We aimed to assess the association of FGF-23 with renal parameters, vascular function and phosphate metabolism in a large cohort of young and healthy individuals. METHODS: Healthy individuals aged 25-41 years were included in a prospective population-based study. Fasting venous blood and morning urinary samples were used to measure plasma creatinine, cystatin C, endothelin-1, phosphate and plasma FGF-23 as well as urinary creatinine and phosphate...

Cardiovascular disease (CVD) is a major cause of morbidity and mortality worldwide. Although numerous modifiable risk factors in the pathogenesis of CVD and its associated mortality have been identified, dyslipidemia remains to be a key focus for therapy. In this regard, significant progress has been made in reducing cardiovascular mortality via the use of lipid-lowering agents such as HMG CoA reductase inhibitors (statins). Yet, despite the disproportionate risk of CVD and mortality in patients with advanced chronic and end stage renal disease (ESRD), treatment of dyslipidemia in this patient population has not been associated with a notable improvement in outcomes...

BACKGROUND: Emerging evidence suggests that chronic metabolic acidosis (CMA) may have significant implications in terms of worsening renal disease in CKD patients, but the effect of CMA on renal function and structure has not been fully elucidated. METHOD: We studied the acute and chronic consequences of an acid load (AL) on glomerular filtration rate (GFR) and renal histology in C57BL/6 mice. FITC-inulin clearance was performed at several time points; markers of renal fibrosis were studied at mRNA and protein levels; finally, kidney expression of candidate molecules triggering changes in renal function was studied...

Chronic kidney disease (CKD) is a global epidemic, and its major risk factors include obesity and type 2 diabetes. Obesity not only promotes metabolic dysregulation and the development of diabetic kidney disease but also may independently lead to CKD by a variety of mechanisms, including endocrine and metabolic dysfunction, inflammation, oxidative stress, altered renal hemodynamics, and lipotoxicity. Deleterious renal effects of obesity can also be transmitted from one generation to the next, and it is increasingly recognized that offspring of obese mothers are predisposed to CKD...

OBJECTIVE: Ketohexokinase (KHK), a primary enzyme in fructose metabolism, has two isoforms, namely, KHK-A and KHK-C. Previously, we reported that renal injury was reduced in streptozotocin-induced diabetic mice which lacked both isoforms. Although both isoforms express in kidney, it has not been elucidated whether each isoform plays distinct roles in the development of diabetic kidney disease (DKD). The aim of the study is to elucidate the role of KHK-A for DKD progression. MATERIALS AND METHODS: Diabetes was induced by five consecutive daily intraperitoneal injections of streptozotocin (50 mg/kg) in C57BL/6 J wild-type mice, mice lacking KHK-A alone (KHK-A KO), and mice lacking both KHK-A and KHK-C (KHK-A/C KO)...
