Frequency. 2% (people in hospital) [1] Hypophosphatemia is an electrolyte disorder in which there is a low level of phosphate in the blood. [1] Symptoms may include weakness, trouble breathing, and loss of appetite. [1] Complications may include seizures, coma, rhabdomyolysis, or softening of the bones.
Frequency. Unclear [2] Hyperphosphatemia is an electrolyte disorder in which there is an elevated level of phosphate in the blood. [1] Most people have no symptoms while others develop calcium deposits in the soft tissue. [1] The disorder is often accompanied by low calcium blood levels, which can result in muscle spasms.
Elevated alkaline phosphatase occurs when levels of alkaline phosphatase (ALP) exceed the reference range. This group of enzymes has a low substrate specificity and catalyzes the hydrolysis of phosphate esters in a basic environment. The major function of alkaline phosphatase is transporting chemicals across cell membranes. [1]
Elevated levels of FGF23 in phosphate diabetes lead to an increase in phosphate excretion through urine, thus reducing the phosphate levels in blood. [5] However, due to impaired activation of vitamin D , which plays a crucial role in increasing intestinal calcium and phosphate absorption, [ 7 ] patients with this disorder are unable to ...
In general, lower levels of enzyme activity correlate with more severe symptoms. The decrease in ALP activity leads to an increase in pyridoxal 5’-phosphate (PLP), which is the major form of Vitamin B6, in the blood, although tissue levels of Vitamin B6 may be unremarkable [30] and correlates with disease severity. [31]
The efficient elimination of phosphorus depends on the kidney’s filtration rate and the phosphorus bioavailability in the blood. [6] Most renal phosphorus is absorbed at the proximal tubules in comparison to the distal nephron. [11] The elevated phosphorus load, or hyperphosphatemia, can reduce the phosphorus reabsorption in the kidney’s ...
A diet insufficient in vitamin D, combined with inadequate sunlight exposure, can lead to vitamin D deficiency, which is defined as a blood 25-hydroxyvitamin D or 25(OH)D level below 12 ng/mL (30 nmol/liter). Vitamin D insufficiency, on the other hand, is characterized by a blood 25(OH)D level between 12–20 ng/mL (30–50 nmol/liter).
A low level of PTH in the blood is known as hypoparathyroidism and is most commonly due to damage to or removal of parathyroid glands during thyroid surgery. There are a number of rare but well-described genetic conditions affecting parathyroid hormone metabolism, including pseudohypoparathyroidism , familial hypocalciuric hypercalcemia , and ...
