[The effect of oral calcium loading on the serum concentrations and urinary excretion of uric acid in patients with recurrent calcium nephrolithiasis and hypercalciuria]. 1990

I Ivanov, and K Tsachev

The authors have established that to higher calciuria in patients with calcium nephrolithiasis correspond higher vales of uric acid serum concentrations and urine excretion than in the controls. In the oral calcium tolerance test a significant correlation was found between the changes in the uric acid urine excretion and those in the diuresis. The following conclusions are put forward. I. In the patients with recurrent calcium nephrolithiasis and hypercalcinosis one should look for active impairment of uric acid metabolism which should be kept in mind when an antirecurrence treatment is planned. 2. The established parallel increase of uricosuria and calciuria in the oral calcium tolerance test means that to patients with recurrent calcium nephrolithiasis and gout a rich calcium diet should not be prescribed since it increases the risk of formation of calcium oxalate stones.

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.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).
