PURPOSE: Dent disease (DD) is a rare tubulopathy characterized by proximal tubular dysfunction leading to chronic kidney disease (CKD). The aim of the study was to characterize patients with DD in Poland. METHODS: A retrospective analysis of a national cohort with genetically confirmed diagnosis. RESULTS: Of 24 males, all patients except one carried mutations in the CLCN5 gene; in one patient a mutation in the OCRL gene was disclosed. Molecular diagnosis was delayed 1 year on average (range 0-21 years)...

Sodium glucose transporter (SGLT)-2 inhibition has renoprotective effects in diabetic kidney disease. Whether similar effects can be achieved also in non-diabetic kidney disease is speculative. Chronic kidney disease was induced in C57BL/6N mice by feeding an oxalate-rich diet for 14 days, known to induce nephrocalcinosis-related tubular atrophy and interstitial fibrosis without directly affecting the glomerular compartment. Empagliflozin treatment started from day 0 of oxalate feeding had no effect on the decline of glomerular filtration rate, crystal deposition, blood urea nitrogen or serum creatinine levels on day 7 and 14...

Crystals can trigger a wide range of kidney injuries that can lead to acute kidney injury, chronic kidney disease, renal colic or nephrocalcinosis, depending on the localization and dynamics of crystal deposition. Studies of the biology of crystal handling by the kidney have shown that the formation of different crystals and other microparticles and the associated mechanisms of renal damage share molecular mechanisms, such as stimulation of the NLRP3 inflammasome or direct cytotoxicity through activation of the necroptosis signalling pathway...

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...

BACKGROUND: Primary hyperoxaluria (PH) is a rare, genetic disorder which involves the overproduction of endogenous oxalate, leading to hyperoxaluria, recurrent urolithiasis and/or progressive nephrocalcinosis and eventually resulting in kidney failure and systemic oxalosis. The aim of this trial was to investigate whether treatment involving an oxalate-metabolising bacterium (Oxalobacter formigenes) could reduce urinary oxalate excretion in PH patients. METHODS: The efficacy and safety of O...

BACKGROUND: Lowe syndrome (LS) and Dent-2 disease (DD2) are disorders associated with mutations in the OCRL gene and characterized by progressive chronic kidney disease (CKD). Here, we aimed to investigate the long-term renal outcome and identify potential determinants of CKD and its progression in children with these tubulopathies. METHODS: Retrospective analyses were conducted of clinical and genetic data in a cohort of 106 boys (LS: 88 and DD2: 18). For genotype-phenotype analysis, we grouped mutations according to their type and localization...

Intrarenal crystals trigger inflammation and renal cell necroptosis, processes that involve TNF receptor (TNFR) signaling. Here, we tested the hypothesis that TNFRs also have a direct role in tubular crystal deposition and progression of hyperoxaluria-related CKD. Immunohistochemical analysis revealed upregulated tubular expression of TNFR1 and TNFR2 in human and murine kidneys with calcium oxalate (CaOx) nephrocalcinosis-related CKD compared with controls. Western blot and mRNA expression analyses in mice yielded consistent data...

Primary hyperoxalurias (PH) are inborn errors in the metabolism of glyoxalate and oxalate with recessive autosomal transmission. As a result, an increased endogenous production of oxalate leads to exessive urinary oxalate excretion. PH type 1, the most common form, is due to a deficiency of the peroxisomal enzyme alanine: Glyoxylate aminotransferase (AGT) in the liver. PH type 2 is due to the deficiency of the glyoxylate reductase/hydroxypyruvate réductase, present in the cytosol of hepatocytes and leucocytes...

Nephrolithiasis is a very common (prevalence around 10 to 12% in France) and recurrent disorder. Nephrolithiasis is associated to chronic kidney disease and is responsible for 2 to 3% of cases of end-stage renal disease, mainly if it is associated to nephrocalcinosis or to a monogenic disorder (1.6% of nephrolithiasis in adults, among them 1% of cystinuria). To understand the underlying pathophysiological processes, stone analysis (morphology and using infrared spectrophotometry) as well as minimal biological assessment including urine crystal research are required...

BACKGROUND: Primary hyperoxaluria type 1 (PH1) and idiopathic hypercalciuria (IHC) are stone-forming diseases that may result in the formation of calcium (Ca) oxalate (Ox) stones, nephrocalcinosis, and progressive chronic kidney disease (CKD). Poorer clinical outcome in PH1 is segregated by the highest urine (Ur)-Ox (UrOx), while IHC outcomes are not predictable by UrCa. We hypothesized that differences would be found in selected Ur-protein (PRO) patterns in PH1 and IHC, compared to healthy intra-familial sibling controls (C) of PH1 patients...

Pathologic calcification is a significant cause of increased morbidity and mortality in patients with chronic kidney disease. The precise mechanisms of ectopic calcification are not fully elucidated, but it is known to be caused by an imbalance of procalcific and anticalcific factors. In the chronic kidney disease population, an elevated phosphate burden is both highly prevalent and a known risk factor for ectopic calcification. Here we tested whether osteopontin, an inhibitor of calcification, protects against high phosphate load-induced nephrocalcinosis and vascular calcification...

BACKGROUND AND OBJECTIVES: Nephrolithiasis is a prevalent condition that affects 10%-15% of adults in their lifetime. It is associated with high morbidity due to colicky pain, the necessity for surgical intervention, and sometimes progression to CKD. In recent years, multiple monogenic causes of nephrolithiasis and nephrocalcinosis have been identified. However, the prevalence of each monogenic gene in a pediatric renal stone cohort has not yet been extensively studied. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: To determine the percentage of cases that can be explained molecularly by mutations in one of 30 known nephrolithiasis/nephrocalcinosis genes, we conducted a high-throughput exon sequencing analysis in an international cohort of 143 individuals <18 years of age, with nephrolithiasis (n=123) or isolated nephrocalcinosis (n=20)...

Dent disease (DD) is a rare X-linked recessive renal tubulopathy characterised by low-molecular-weight proteinuria (LMWP), hypercalciuria, nephrocalcinosis and/or nephrolithiasis. DD is caused by mutations in both the CLCN5 and OCRL genes. CLCN5 encodes the electrogenic chloride/proton exchanger ClC-5 which is involved in the tubular reabsorption of albumin and LMW proteins, OCRL encodes the inositol polyphosphate 5-phosphatase, and was initially associated with Lowe syndrome. In approximately 25 % of patients, no CLCN5 and OCRL mutations were detected...

BACKGROUND: Familial hypomagnesemia with hypercalciuria and nephrocalcinosis is a rare autosomal recessive renal disease characterized by tubular disorders at the thick ascending limb of Henle's loop. It is caused by mutations in the tight junction structural proteins claudin-16 or claudin-19, which are encoded by the CLDN16 and CLDN19 genes, respectively. Patients exhibit excessive wasting of calcium and magnesium, nephrocalcinosis, chronic kidney disease, and early progression to end-stage renal failure during infancy...

AIM: Nephrocalcinosis is a clinical-pathological entity characterized by the deposition of calcium salts within the kidney parenchyma. Both the protean presentation and multiple causes may explain the lack of data regarding its prevalence. The aim of this study is to report the prevalence and main clinical features of nephrocalcinosis diagnosed in a newly opened nephrology outpatient unit. METHODS: Analysis on the data we prospectively gathered from the start of activity (2007-2013) was carried out...

Hyperoxaluria is characterized by an increased urinary excretion of oxalate. Primary and secondary hyperoxaluria are two distinct clinical expressions of hyperoxaluria. Primary hyperoxaluria is an inherited error of metabolism due to defective enzyme activity. In contrast, secondary hyperoxaluria is caused by increased dietary ingestion of oxalate, precursors of oxalate or alteration in intestinal microflora. The disease spectrum extends from recurrent kidney stones, nephrocalcinosis and urinary tract infections to chronic kidney disease and end stage renal disease...

Familial hypomagnesaemia with hypercalciuria and nephrocalcinosis is an autosomal-recessive disease caused by mutations in the CLDN16 or CLDN19 genes, which encode tight junction-associated proteins, claudin-16 and -19. The resultant tubulopathy leads to urinary loss of Mg(2+) and Ca(2+), with subsequent nephrocalcinosis and end-stage renal disease (ESRD). An 18-year-old boy presented with chronic kidney disease and proteinuria, as well as hypomagnesaemia, hypercalciuria and nephrocalcinosis. A kidney biopsy revealed tubular atrophy, interstitial fibrosis and segmental sclerosis of some glomeruli...

Subcutaneous fat necrosis of the newborn is an uncommon, transient and self-healing panniculits. This entity generally follows an uncomplicated course, however there are rare and important complications. The authors present a case of a newborn with subcutaneous fat necrosis complicated by hypercalcemia and nephrocalcinosis. The pathogenesis of hypercalcemia is not fully understood and the nephrocalcinosis can evolve to chronic kidney disease. Clinicians should be aware of subcutaneous fat necrosis as a possible risk factor for hypercalcemia and patients should have serial serum and urinary calcium determinations for up to 6 months after the appearance of the skin lesions...

Hyperoxaluria is a frequent complication of inflammatory bowel diseases, ileal resection and Roux-en-Y gastric bypass and is well-known to cause nephrolithiasis and nephrocalcinosis. The associated prevalence of chronic kidney disease and end-stage kidney disease (ESKD) is less clear but may be more consequential than recognized. In this review, we highlight three cases of ESKD due to enteric hyperoxaluria following small bowel resections. We review current information on the pathophysiology, complications and treatment of this complex disease...

BACKGROUND: Experimental data indicate that microscopic calcium phosphate deposition in the kidney (nephrocalcinosis) may accelerate progression of chronic kidney disease (CKD). Data on the prevalence, risk factors and implications of nephrocalcinosis in CKD patients are scarce. A mineral metabolism disorder could play an important pathogenetic role, as suggested by recent protocol biopsy findings in incident renal transplant recipients. METHODS: Kidney biopsy cylinders of CKD patients, collected between January 1989 and December 2007, were screened for the presence of nephrocalcinosis...
