Inborn errors of metabolism in the 21 century: past to present.

Ann Transl Med 2018 Dec;6(24):467

Department of Pediatrics, University of Pittsburgh Medical Center, Pittsburgh, PA, USA.

The 21 century is an exciting time to be in the field of metabolic medicine. As with many fields, one of the keys to anticipating the future is to understand the past. The term "inborn error of metabolism" was first coined in 1908 by Sir Archibald Garrod, in reference to four disorders (alkaptonuria, pentosuria, cystinuria and albinism). Read More

Urinary proteome in inherited nephrolithiasis.

Urolithiasis 2019 Feb 18;47(1):91-98. Epub 2018 Dec 18.

Chair of Nephrology, Department of Translational Medicine, University of Campania "Luigi Vanvitelli", Naples, Italy.

In the last decades, proteomics has been largely applied to the Nephrology field, with the double aim to (1) elucidate the biological processes underlying renal diseases; (2) identify disease-specific biomarkers, predictor factors of therapeutic efficacy and prognostic factors of disease progression. Kidney stone disease, and in particular, inherited nephrolithiasis (INL) are not an exception. Given the multifactorial origin of these disorders, the combination of genomics and proteomics studies may complement each other, with the final objective to give a global and comprehensive mechanistic view.

Amino Acid Transport Across the Mammalian Intestine.

Compr Physiol 2018 Dec 13;9(1):343-373. Epub 2018 Dec 13.

Research School of Biology, The Australian National University, Canberra, ACT 2601, Australia.

The small intestine mediates the absorption of amino acids after ingestion of protein and sustains the supply of amino acids to all tissues. The small intestine is an important contributor to plasma amino acid homeostasis, while amino acid transport in the large intestine is more relevant for bacterial metabolites and fluid secretion. A number of rare inherited disorders have contributed to the identification of amino acid transporters in epithelial cells of the small intestine, in particular cystinuria, lysinuric protein intolerance, Hartnup disorder, iminoglycinuria, and dicarboxylic aminoaciduria.

Living kidney donation from people at risk of nephrolithiasis, with a focus on the genetic forms.

Urolithiasis 2019 Feb 23;47(1):115-123. Epub 2018 Nov 23.

UOC Nefrologia, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy.

Deciding whether to accept a donor with nephrolithiasis is a multifaceted task because of the challenge of finding enough suitable donors while at the same time ensuring the safety of both donors and recipients. Until not long ago, donors with a history of renal stones or with stones emerging during screening on imaging were not considered ideal, but recent guidelines have adopted less stringent criteria for potential donors at risk of stones. This review goes through the problems that need to be approached to arrive at a wise clinical decision, balancing the safety of donors and recipients with the need to expand the organ pool.

An N-Ethyl-N-Nitrosourea (ENU)-Induced Tyr265Stop Mutation of the DNA Polymerase Accessory Subunit Gamma 2 (Polg2) Is Associated With Renal Calcification in Mice.

J Bone Miner Res 2018 Nov 5. Epub 2018 Nov 5.

Academic Endocrine Unit, Oxford Centre for Diabetes, Endocrinology and Metabolism, Radcliffe Department of Medicine, University of Oxford, Oxford, UK.

Renal calcification (RCALC) resulting in nephrolithiasis and nephrocalcinosis, which affects ∼10% of adults by 70 years of age, involves environmental and genetic etiologies. Thus, nephrolithiasis and nephrocalcinosis occurs as an inherited disorder in ∼65% of patients, and may be associated with endocrine and metabolic disorders including: primary hyperparathyroidism, hypercalciuria, renal tubular acidosis, cystinuria, and hyperoxaluria. Investigations of families with nephrolithiasis and nephrocalcinosis have identified some causative genes, but further progress is limited as large families are unavailable for genetic studies.

Renal stones in two children with two rare etiologies.

Saudi J Kidney Dis Transpl 2018 Sep-Oct;29(5):1203-1206

Department of Pediatric Nephrology, Sheikh Khalifa Medical City, Abu Dhabi, UAE.

The incidence of urolithiasis in children has shown an increase in recent years which may be attributed to changing dietary patterns, sedentary lifestyles, and obesity. Among the various etiologies for renal stones in children, two rare entities worth mentioning are cystinuria and 2, 8-dihydroxyadenine (DHA) urolithiasis. Cystinuria is an inherited cause of nephrolithiasis which occurs due to impaired cystine reabsorption in the renal proximal tubule. Read More

Bioorg Med Chem Lett 2018 05 10;28(8):1303-1308. Epub 2018 Mar 10.

Department of Medicinal Chemistry, Ernest Mario School of Pharmacy, Rutgers, The State University of New Jersey, 160 Frelinghuysen Road, Piscataway, NJ 08854, United States. Electronic address:

To overcome the chemical and metabolic stability issues of l-cystine dimethyl ester (CDME) and l-cystine methyl ester (CME), a series of l-cystine diamides with or without N-methylation was designed, synthesized, and evaluated for their inhibitory activity of l-cystine crystallization. l-Cystine diamides 2a-i without N-methylation were found to be potent inhibitors of l-cystine crystallization while N-methylation of l-cystine diamides resulted in derivatives 3b-i devoid of any inhibitory activity of l-cystine crystallization. Computational modeling indicates that N-methylation leads to significant decrease in binding of the l-cystine diamides to l-cystine crystal surface. Read More

Smith Institute for Urology, Hofstra Northwell School of Medicine, Lake Success, NY, USA.

Over 1%-15% of the population worldwide is affected by nephrolithiasis, which remains the most common and costly disease that urologists manage today. Identification of at-risk individuals remains a theoretical and technological challenge. The search for monogenic causes of stone disease has been largely unfruitful and a technological challenge; however, several candidate genes have been implicated in the development of nephrolithiasis.

Clinical Outcomes for Cystinuria Patients with Unilateral Versus Bilateral Cystine Stone Disease.

J Endourol 2018 02 3;32(2):148-153. Epub 2018 Jan 3.

1 Department of Urology, University of California , San Francisco, San Francisco, California.

Introduction: Cystinuria is a genetic disorder marked by elevated urinary cystine excretion and recurrent cystine nephrolithiasis. Interestingly, despite seemingly similar contralateral renal anatomy, a subset of cystinuric patients consistently form stones in only one kidney. The aim of this study is to evaluate clinical outcomes in unilateral vs bilateral cystine stone formers. Read More

Frequency of five disease-causing genetic mutations in a large mixed-breed dog population (2011-2012).

PLoS One 2017 22;12(11):e0188543. Epub 2017 Nov 22.

Department of Basic Medical Sciences, College of Veterinary Medicine, Purdue University, West Lafayette, Indiana, United States of America.

Background: A large and growing number of inherited genetic disease mutations are now known in the dog. Frequencies of these mutations are typically examined within the breed of discovery, possibly in related breeds, but nearly always in purebred dogs. No report to date has examined the frequencies of specific genetic disease mutations in a large population of mixed-breed dogs. Read More

Do Urinary Cystine Parameters Predict Clinical Stone Activity?

J Urol 2018 Feb 12;199(2):495-499. Epub 2017 Sep 12.

Department of Urology, University of Texas Southwestern Medical Center, Dallas, Texas; Jane and Charles Pak Center for Mineral Metabolism and Clinical Research, Dallas, Texas. Electronic address:

Purpose: An accurate urinary predictor of stone recurrence would be clinically advantageous for patients with cystinuria. A proprietary assay (Litholink, Chicago, Illinois) measures cystine capacity as a potentially more reliable estimate of stone forming propensity. The recommended capacity level to prevent stone formation, which is greater than 150 mg/l, has not been directly correlated with clinical stone activity. Read More

A multiregional Italian cohort of 24-hour urine metabolic evaluation in renal stone formers.

Minerva Urol Nefrol 2018 Feb 7;70(1):87-94. Epub 2017 Sep 7.

Department of Urology, University of Rome Tor Vergata, Rome, Italy.

Background: Nephrolithiasis is a common condition with several studies documenting an increased prevalence over the past four decades. EAU and AUA guidelines recommend 24-hour urine metabolic evaluation in high-risk stone formers. Aim of this study is to retrospectively evaluate the first three years of experience with LithoTest® (Biohealth Italia Srl, Turin, Italy) through the analysis of demographic, clinical and biochemical data collected from a large cohort of patients with kidney stones.

Mass Spectrometry-based Assay to Identify Drugs that Influence Cystine Solubility.

Bio Protoc 2017 Jul;7(14)

Department of Urology, University of California, San Francisco, CA, USA.

Cystinuria is a rare genetic disorder characterized by recurrent, painful kidney stones, primarily composed of cystine, the dimer of the amino acid cysteine (Sumorok and Goldfarb, 2013). Using a mouse model of cystinuria, we have recently shown that administration of drugs that increase cystine solubility in the urine can be a novel therapeutic strategy for the clinical management of the disease (Zee ., 2017).

Clin J Am Soc Nephrol 2017 Oct 22;12(10):1699-1708. Epub 2017 Aug 22.

Section of Nephrology, Department of Medicine, University of Chicago, Chicago, Illinois

Nephrolithiasis is highly prevalent across all demographic groups in the Western world and beyond, and its incidence rates are rising. In addition to the morbidity of the acute event, stone disease often becomes a lifelong problem that requires preventative therapy to diminish ongoing morbidity. Across the majority of stone types, increased fluid intake and targeted dietary modifications are mainstays of therapy. Read More

Associating mutations causing cystinuria with disease severity with the aim of providing precision medicine.

BMC Genomics 2017 08 11;18(Suppl 5):550. Epub 2017 Aug 11.

School of Biosciences, University of Kent, Canterbury, Kent, CT2 7NJ, UK.

Background: Cystinuria is an inherited disease that results in the formation of cystine stones in the kidney, which can have serious health complications. Two genes (SLC7A9 and SLC3A1) that form an amino acid transporter are known to be responsible for the disease. Variants that cause the disease disrupt amino acid transport across the cell membrane, leading to the build-up of relatively insoluble cystine, resulting in formation of stones. Read More
