Nephrolithiasis and Nephrocalcinosis in Children - Metabolic and Genetic Factors.

Nephrolithiasis and Nephrocalcinosis in Children - Metabolic and Genetic Factors. Pediatr Endocrinol Rev. 2015 Sep;13(1):468-76 Authors: Tasic V, Gucev Z Abstract Diagnosis and management of pediatric nephrolithiasis/nephrocalcinosis is a very complex and challenging task for every pediatrician. It is based on correct. disease history taking, which may guide to the mode of inheritance (dominant, recessive, x-linked). Ethnicity and consanguinity should also be investigated since they predispose to high prevalence of certain disorders. One should always begin with cheap and available screening tests. Herein we will review clinical, biochemical, metabolic and genetic characteristics of the inherited diseases which lead to nephrolithiasis/nephrocalcinosis, such as: idiopathic hypercalciuria, renal hypophosphatemia, renal tubular acidosis, idiopathic infantile hypercalcemia, Dent disease, familial hypomagnesemia with hypercalciuria and nephrocalcinosis, hypocitraturia, cystinuria, primary hyperoxaluria and renal hypouricemia. Modern genetic techniques such as next generation sequencing enable nowadays diagnosis of rare disease using only a blood sample, trough massive parallel resequencing of many genes. This is very helpful for anuric patients or on dialysis where blood and urine biochemistry are not informative. Genetic testing also replaces invasive liver biopsy or unpleasant acidification tests and enables prenatal or early postnatal ...
