Selective protein enrichment in calcium oxalate stone matrix: a window to pathogenesis?

Urolithiasis 2019 Apr 16. Epub 2019 Apr 16.

Department of Medicine/Division of Nephrology, Medical College of Wisconsin, 9200 W Wisconsin Avenue, Milwaukee, WI, 53226, USA.

Urine proteins are thought to control calcium oxalate stone formation, but over 1000 proteins have been reported in stone matrix obscuring their relative importance. Proteins critical to stone formation should be present at increased relative abundance in stone matrix compared to urine, so quantitative protein distribution data were obtained for stone matrix compared to prior urine proteome data. Matrix proteins were isolated from eight stones (> 90% calcium oxalate content) by crystal dissolution and further purified by ultradiafiltration (> 10 kDa membrane). Read More

Educational review: role of the pediatric nephrologists in the work-up and management of kidney stones.

Pediatr Nephrol 2019 Jan 4. Epub 2019 Jan 4.

Department of Pediatrics, Schulich School of Medicine & Dentistry, University of Western Ontario, London, ON, N6A 5W9, Canada.

Background: The incidence of nephrolithiasis in children and adolescents is increasing and appears to double every 10 years. The most important role of the pediatric nephrologist is to diagnose and modify various metabolic and non-metabolic risk factors, as well as prevent long-term complications especially in the case of recurrent nephrolithiasis.

Objective: The purpose of this review is to summarize the existing literature on the etiology and management of pediatric nephrolithiasis. Read More

Trans-ethnic kidney function association study reveals putative causal genes and effects on kidney-specific disease aetiologies.

Nat Commun 2019 01 3;10(1):29. Epub 2019 Jan 3.

Department of Epidemiology, University of North Carolina, Chapel Hill, NC, 27516-8050, USA.

Chronic kidney disease (CKD) affects ~10% of the global population, with considerable ethnic differences in prevalence and aetiology. We assemble genome-wide association studies of estimated glomerular filtration rate (eGFR), a measure of kidney function that defines CKD, in 312,468 individuals of diverse ancestry. We identify 127 distinct association signals with homogeneous effects on eGFR across ancestries and enrichment in genomic annotations including kidney-specific histone modifications. Read More

Inhibiting inflammation and modulating oxidative stress in oxalate-induced nephrolithiasis with the Nrf2 activator dimethyl fumarate.

Free Radic Biol Med 2018 Dec 29;134:9-22. Epub 2018 Dec 29.

Department and Institute of Urology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei, China.

Hyperoxaluria induces oxidative stress, and inflammation causes renal epithelial cell injury in nephrolithiasis, suggesting that reduced oxalate toxicity may be beneficial. This study aimed to investigate whether nuclear factor (erythroid-derived 2)-like 2 (Nrf2, also called Nfe2l2) induced by dimethyl fumarate (DMF) could protect renal epithelial cells against oxalate-mediated injury both in vivo and in vitro. Glyoxylic acid monohydrate was intraperitoneally injected into Sprague-Dawley rats with or without intragastric administration of DMF. Read More

Ceftriaxone-associated nephrolithiasis and gallstone in adults.

Drug Healthc Patient Saf 2018 12;10:103-108. Epub 2018 Dec 12.

Infectious Disease Research Center, Birjand University of Medical Sciences, Birjand, Iran,

Background: Ceftriaxone (CTX) is widely used for the treatment of bacterial infections; however, side effects such as gallstone and nephrolithiasis have been reported in children. There is limited information about urinary tract calculi as CTX side effects in adults. Therefore, the present study was aimed to evaluate the incidence of gallstone and nephrolithiasis following CTX administration. Read More

Intra-operative Postperfusion Micronephrolithotomy for Renal Allograft Lithiasis: A Case Report.

Transplant Proc 2018 Dec 29;50(10):3950-3953. Epub 2018 May 29.

Kidney Transplantation, Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico, Milan, Italy; Department of Clinical Sciences and Community Health, University of Milan, Milan, Italy. Electronic address:

Increasing demand drives the expansion of criteria for kidney donation, and nephrolithiasis is now considered a relative contraindication. We report for the first time a case of intra-operative, postperfusion kidney allograft micronephrolithotomy. A 64-year-old man with end-stage renal disease secondary to Alport syndrome underwent primary deceased donor kidney transplantation at our center. Read More
