[Calcium excretion in patients with calcium oxalate calculi in acid administration]. 1987

C Bothor, and W Berg, and W Pirlich

Acidosis induced increase in renal calcium excretion was produced by means of ammonium chloride load in 12 control persons and in 76 patients with recurrent oxalate lithiasis. This increase is more marked in stone patients - even in those with normocalciuria - than in control persons. The calcium excretion is especially increased in patients with renal hypercalciuria. This might result from the primary nature of the renal defect. The acid load did not prove useful in the diagnosis of hyperparathyroidism.

UI	MeSH Term	Description	Entries
D006961	Hyperparathyroidism	A condition of abnormally elevated output of PARATHYROID HORMONE (or PTH) triggering responses that increase blood CALCIUM. It is characterized by HYPERCALCEMIA and BONE RESORPTION, eventually leading to bone diseases. PRIMARY HYPERPARATHYROIDISM is caused by parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS. SECONDARY HYPERPARATHYROIDISM is increased PTH secretion in response to HYPOCALCEMIA, usually caused by chronic KIDNEY DISEASES.
D007669	Kidney Calculi	Stones in the KIDNEY, usually formed in the urine-collecting area of the kidney (KIDNEY PELVIS). Their sizes vary and most contains CALCIUM OXALATE.

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.
