Low urinary calcium excretion in Bartter's syndrome. 1988

A Rudin, and M Aurell, and J Wilske

Department of Endocrinology, University of Göteborg, Sweden.

The urinary calcium excretion has been determined in 19 patients with Bartter's syndrome and found to be significantly lower than the calcium excretion in 92 healthy subjects (1.16 +/- 0.82 vs. 4.36 +/- 2.71 mmol/24 h, p less than 0.001). There were no differences in height, weight, glomerular filtration rate, urinary sodium excretion or serum calcium concentration between the patients and the control subjects to account for the disparity in calcium excretion. In the patients, the concentrations for ionized calcium, PTH, 25-OH vitamin D and 1,25-(OH)2 vitamin D were normal. A low urinary calcium excretion appears to be a characteristic feature of Bartter's syndrome. The cause remains unexplained.

UI	MeSH Term	Description	Entries
D008274	Magnesium	A metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION.
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.

D001477	Bartter Syndrome	A group of disorders caused by defective salt reabsorption in the ascending LOOP OF HENLE. It is characterized by severe salt-wasting, HYPOKALEMIA; HYPERCALCIURIA; metabolic ALKALOSIS, and hyper-reninemic HYPERALDOSTERONISM without HYPERTENSION. There are several subtypes including ones due to mutations in the renal specific SODIUM-POTASSIUM-CHLORIDE SYMPORTERS.
