We examined whether a difference in potassium dihydrogenphosphate (KH2PO4) and potassium tripolyphosphate (K5P3O10) as dietary phosphorus sources could differentially effect the nephrocalcinosis and proximal tubular function in female rats. Rats were fed on a diet containing KH2PO4 or K5P3O10, at
Identification of a monogenic etiology is possible in a proportion of patients with childhood-onset nephrolithiasis or nephrocalcinosis. Bartter syndrome (BS), a hereditary tubulopathy characterized by polyuria, hypokalemic alkalosis and growth retardation that rarely presents with isolated
We report a 41-year-old man with hypomagnesemia, hypercalciuria, nephrocalcinosis, myopia and horizontal nystagmus. The hypomagnesemia was due to primary renal magnesium loss. He was diagnosed as having the syndrome of renal hypomagnesemia, hypercalciuria and nephrocalcinosis. This is a rare
Nephrocalcinosis (NC) occurs frequently in preterm neonates. A high U-calcium/citrate is one of the contributing factors to the development of NC. In stone-forming children and adults citrate supplementation is a successful preventive therapy. In this randomized controlled trial the effect of
Renal injury in early life may lead to hypertension and renal disease in adulthood. In this prospective study, we estimated renal glomerular and tubular function and kidney length (KL) during the first 2 years of life of preterm infants with nephrocalcinosis (NC) associated with prematurity. The
BACKGROUND
Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is a rare autosomal recessive tubular disorder that eventually progresses to renal failure, depending upon the extent of nephrocalcinosis. Its basic pathogenesis is impaired tubular resorption of magnesium and
The objective of this study was to determine the incidence and risk factors of nephrocalcinosis (NC) in pre-term neonates in the neonatal intensive care unit (NICU) at the Al-Minya University, Egypt. The study included 97 pre-term neonates with a gestational age 34 weeks. Data on duration of
Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is a rare autosomal recessive disease caused by mutations in the CLDN16 or CLDN19 gene; however, few cases develop classical amelogenesis imperfecta. Herein, we report the case of a boy with early clinical renal manifestations
Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is a rare autosomal recessive tubular disorder that is frequently associated with progressive renal failure. The primary defect is related to impaired tubular reabsorption of magnesium (Mg) and calcium (Ca) in the thick
To assess the impact of prematurity-associated nephrocalcinosis on kidney function later in life, 20 premature children with neonatal nephrocalcinosis and 20 controls, matched for birth weight and postnatal age but without nephrocalcinosis, were examined (birth weight 905+/-209 vs. 957+/-226 g;
Distal renal tubular acidosis is a defect of acidification of urine in distal tubule. Full-blown form is characterized by polyuria, growth deficiency, nephrolithiasis or nephrocalcinosis. Mutations in genes encoding Cl-/HCO3 - exchanger (autosomal dominant) or H+-ATPase (autosomal BACKGROUND
A diagnostic workup of a renal mass will rarely lead to the diagnosis of a tubulopathy. We would like to stress the importance of taking a detailed history and of evaluating these findings in the context of the clinical symptoms.
METHODS
A 3 year old boy with a renal mass, diagnosed due
An animal model was established to test the effect of a calcium antagonist on nephrocalcinosis, which was induced by an atherogenous diet, and its effect on the excretion of calcium and other parameters relevant for stone formation. With the administration of nifedipine (Adalat), the grade of
