37 Possible Causes for Urinary Excretion of Calcium and Phosphate Decreased

  • Vitamin D Deficiency

    In stage 1 VDDR, urinary amino acid and phosphate excretion are normal with minimal or no findings of rickets on radiographs.[ncbi.nlm.nih.gov] […] and inorganic phosphate concentrations, secondary hyperparathyroidism and decreased serum 25-hydroxyvitamin D (25(OH)D) levels.[ncbi.nlm.nih.gov] Vitamin D deficiency rickets (VDDR) is a disorder biochemically characterized by elevated serum alkaline phosphatase (ALP) activity, normal or decreased serum calcium (Ca)[ncbi.nlm.nih.gov]

  • Renal Stone

    In-flight changes previously observed include decreased urine volume and increased urinary excretion of calcium, phosphate, and sodium.[nasa.gov]

  • High Calcium Diet

    From these findings, intake of mild high-calcium diet appears to be beneficial to decrease the urinary oxalate excretion and PSF in patients with idiopathic hypercalciuria[ncbi.nlm.nih.gov] Pyridoxal phosphate has all the features of suppressing such risk factors for stone formation in patients with idiopathic hypercalciuria.[ncbi.nlm.nih.gov]

  • Hypercalcemia

    […] formation Increases urinary excretion of calcium Other factors altering serum calcium include the following: Metabolic alkalosis, which causes an increase in tubular calcium[emedicine.com] Urinary calcium excretion is usually normal or high in cancer.[web.archive.org] […] reabsorption Phosphate-induced decrease of serum calcium levels and increase of PTH Stimulation of osteoclasts by cytokines, such as tumor necrosis factor, interleukin-1,[emedicine.com]

  • Senile Osteoporosis

    excretion; (e) modification of calcium balance toward positive, due to decreased urinary and faecal calcium and to an improvement in intestinal absorption. 2. 47 Calcium[clinsci.org] […] levels; (b) slight diminution of plasma phosphate level and urinary phosphate clearance; (c) lowering of serum alkaline phosphatase values; (d) diminution of urinary hydroxyproline[clinsci.org] […] for 55–60 days with 25 MRC Units per day of porcine thyrocalcitonin with the following metabolic results: (a) slight diminution of plasma, urinary and endogenous faecal calcium[clinsci.org]

  • Osteitis Fibrosa Cystica

    Similar to those of serum calcium, serum phosphorus levels remain within the normal range until CKD stages 4 to 5 are reached, when decreased GFR limits urinary phosphate[doi.org] excretion.[doi.org]

  • Nephrocalcinosis

    Phosphate deficiency is typically associated with hypercalciuria, whereas phosphate supplementation decreases urinary calcium excretion. 28 Excess phosphate administration[fn.bmj.com] , phosphate, and fluid and raised serum creatinine and urea.[fn.bmj.com] […] significantly associated with nephrocalcinosis, and we confirm the work of Short and Cooke 4 showing that nephrocalcinosis is significantly associated with low intake of calcium[fn.bmj.com]

  • X-Linked Osteoporosis with Fractures

    Serum calcium and phosphate levels were normal in all affected male family members, as was urinary calcium excretion, which was measured in several of the affected patients[nejm.org] No consistent decrease or increase in bone-turnover markers was observed.[nejm.org]

  • Familial Hypocalciuric Hypercalcemia Type 2

    Urinary calcium excretion is usually normal or high in cancer.[merckmanuals.com] In humoral hypercalcemia of cancer, PTH is often decreased or undetectable; phosphate is often decreased; and metabolic alkalosis, hypochloremia, and hypoalbuminemia are often[merckmanuals.com] Increase urinary calcium excretion Decrease bone resorption Remove excess calcium through dialysis The treatment used depends on both the degree and the cause of hypercalcemia[merckmanuals.com]

  • Milk-Alkali Syndrome

    Urinary calcium excretion is usually normal or high in cancer.[merckmanuals.com] In humoral hypercalcemia of cancer, PTH is often decreased or undetectable; phosphate is often decreased; and metabolic alkalosis, hypochloremia, and hypoalbuminemia are often[merckmanuals.com] Increase urinary calcium excretion Decrease bone resorption Remove excess calcium through dialysis The treatment used depends on both the degree and the cause of hypercalcemia[merckmanuals.com]
