If levels of phosphate in the blood become too high, it may cause mineral and bone disorders and calcification. Nobody should take more than 250 milligrams (mg) of phosphorus supplements per day. Several drugs induce hypophosphatemia through increased renal Pi excretion. Hypophosphatemia resulting from more than one mechanism, Drug-induced metabolic acidosis (alcohol, toluene), Drugs that cause vitamin D deficiency or resistance: phenytoin, phenobarbital, Anticancer drugs: ifosfamide, streptozocin, azacitidine, suramin, Antibiotics: tetracyclines, aminoglycosides, Antiviral agents:cidofovir, adefovir, tenofovir, Copyright © 2021 Association of Physicians of Great Britain and Ireland. Correct The most common cause is kidney disease, but other conditions can lead to phosphate levels being out of balance. Some of these mediators of redistributional hypophosphatemia deserve a more detailed analysis. Renal and intestinal phosphate reabsorption is also mediated by multiple hormonal and non-hormonal factors. Hyperphosphatemia itself is generally asymptomatic. The type II cotransporter comprises three highly homologous isoforms: types IIa and IIc, which are located in the brush-border membrane of the proximal tubules, and type IIb, which is not expressed in the kidney but is responsible for intestinal Pi absorption.14–16, Hypophosphatemia results from the following processes either alone or in any combination: transcellular shift of Pi from the extracellular fluid into cells, increased Pi excretion via the kidneys, and decreased intestinal Pi absorption. Too much phosphate in the blood is known as hyperphosphatemia. The doctor will insert a needle into a vein in the arm and take a small sample of blood that will be sent to a laboratory for testing. Getting the root cause taken care of can help dramatically. All rights reserved. It is a particularly serious condition as the heart will need to work harder to pump blood around the body. We also look at tips for treating and preventing smelly farts. First, limit foods that are high in phosphorus, such as: milk. The kidney and (to a lesser extent) small intestine are the main organs that participate in the regulation of Pi homeostasis (Figure 1B).9 Phosphate is plentiful in the diet. Hyperphosphatemia suppresses the renal hydroxylation of inactive 25-hydroxyvitamin D to calcitriol, so serum calcitriol levels are low when the GFR is less than 30 mL/min/1.73 m². Treatment for hyperphosphatemia will depend on the underlying cause: The main way to prevent hyperphosphatemia is to control the levels of phosphate and calcium in the body. A person will need to collect all of their urine over a set period, which is usually 24 hours. If this happens in children who have kidney disease, it can be more serious as their bones are still developing. In a retrospective study, 21 out of 35 patients (67%) exhibited hypophosphatemia after major hepatic surgery. (B) Major determinants of serum phosphate. Hypophoshatemia is infrequent in the general population and is mainly encountered in hospitalized patients (ranging from 2.2 to 3.1%) or patients admitted to intensive care units (28.8–34%), as well as those with chronic alcoholism (2.5–30.4%), major trauma (up to 75%) and sepsis (65–80%).1, Serum phosphate or phosphorus normally ranges from 2.5 to 4.5 mg/dl (0.81–1.45 mmol/l) in adults. Oxford University Press is a department of the University of Oxford. Hyperphosphatemia as it occurs during hemoconcentration or decreased glomerular filtration is unlikely to be of any clinical relevance. They also decrease calcium resorption in the gut. However, if the kidneys are not working efficiently, they may not be able to remove enough phosphate, leading to high levels in the body. For instance, the offending drug should be discontinued and vitamin D should be supplemented in subjects with vitamin D insufficiency). Respiratory alkalosis plays a major role in the hypophosphatemia of acute salicylate intoxication and mechanical ventilation of patients suffering from severe asthma or chronic obstructive pulmonary disease exacerbations.22,23 It should be noted that respiratory alkalosis represents the earliest acid–base abnormality of salicylate intoxication due to a direct stimulation of the respiratory center, while metabolic acidosis because of the accumulation of organic acids ensues. Finally, inappropriate phosphaturia may play a role in the pathogenesis of hypophosphatemia. Nonetheless, patients not infrequently receive more than one drug that can negatively affect the renal handling of phosphate as for example in the case of patients with chronic obstructive pulmonary disease who receive xanthine derivatives, corticosteroids, loop diuretics, and/or beta 2-adrenergic bronchodilators and are consequently prone to develop hypophosphatemia. Awareness of this undesired effect of certain pharmaceutical agents on serum phosphorous concentrations facilitates a rational clinical management of a potentially life threatening disorder, especially in patients at high-risk for the development of hypophosphatemia, such as alcoholics. Hyperphosphatemia is also seen in people who have: Excessive dietary intake of phosphate (also from laxatives or enemas) PTH normally inhibits reabsorption of phosphate by the kidney.

Mild-to-moderate use of such phosphate binders generally poses no threat to phosphate homeostasis because dietary ingestion greatly exceeds body needs. Phosphate is a chemical found in the body. Herein, we review the clinical information of hypophosphatemia associated with specific drug treatment and discuss the underlying pathophysiology. Interestingly, hypophosphatemia is the most frequent electrolyte disorder in patients with hyponatremia due to SIADH.48 Taking into account that numerous drugs can induce SIADH, they should also be considered as a potential cause of hypophosphatemia.77, Finally, increased renal phosphate excretion due to downregulation of Na–Pi-IIa co-transporter has been proposed as the possible explanation of acyclovir-induced hypophosphatemia.78,79, Metabolic acidosis induces renal wasting of phosphate disproportionate to its effect on mobilization of tissue phosphorus. Causes include alcohol use disorder, burns, starvation, and diuretic use. The risk of severe hypophosphatemia is increased in cases of underlying phosphate depletion. Hypoparathyroidism: In this situation, there are low levels of parathyroid hormone (PTH). Hyperphosphatemia manifests as either an acute or a chronic case. Hypophosphatemia has repeatedly been associated with phosphate-binding antacids.38,39 In fact, absorption of phosphate can be blocked by commonly used over-the-counter aluminum-, calcium- and magnesium-containing antacids. The kidneys balance the amount of phosphorus and calcium in the blood.

Causes of hyperphosphatemia include impaired phosphorus excretion (renal failure or hypoparathyroidism), redistribution of phosphorus to the extracellular fluid (acid-base imbalance, rhabdomyolysis, muscle necrosis, or tumor lysis during chemotherapy), and increased phosphate intake. Sort by: Most Popular. Hypophosphatemia due to the movement of Pi from the extracellular to intracellular compartment is common. Last medically reviewed on January 6, 2018. MNT is the registered trade mark of Healthline Media. Bones need minerals and hormones to rebuild, grow, and stay strong. Beyond foods and drinks, medications may be a significant source of phosphate that adds to patients’ daily load. Normal total body phosphorus content in an average adult is 700 g (10 g/kg body weight), of which 85% is contained in skeleton, 14% in soft tissues, and only 1% in the extracellular fluid (Figure 1A). Secondary hyperparathyroidism due to diminished calcium levels might also play a contributing role in the development of hypophosphatemia in this setting.74,75, Volume expansion (e.g. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Mild, transient and usually asymptomatic hypophospatemia is frequently associated with bisphosphonate therapy. Processed foods often contain phosphorus as a preservative, shown by ingredients that have the letters PHOS together. Phosphorus is found in bone, soft tissue and within the extracellular fluid. What should my cholesterol level be at my age? Pathophysiologic implications, clinical presentations, and treatment, © The Author 2010. PTH pulls calcium from your bones to try and put your blood back in balance. Although most patients with hyperphosphatemia are asymptomatic, they occasionally report hypocalcemic symptoms, such as muscle cramps, tetany, and perioral numbness or tingling. So what’s the big deal? Symptoms include lower levels of calcium, high levels of parathyroid hormone, and bone pain. Symptoms. Hypophosphatemia (serum phosphorus concentration <2.5 mg/dl, 0.8 mmol/l), although rare in the general population, is commonly observed in hospitalized patients and may be associated with drug therapy. When taken with a meal, the drug controls the amount of phosphorus that the body absorbs from the food.

Hypocalcemia may cause symptoms, for example: Paresthesias (tingling around mouth, hands) Muscle cramping, weakness, laryngospasm Question 18 of 20 A patient is diagnosed with drug-related hyperphosphatemia. colas. Experimental studies have demonstrated that volume expansion evoked an inhibition of phosphate uptake by the renal proximal tubules.76 Furthermore, hypophosphatemia in patients with syndrome in appropriate antidiuretic hormone secretion (SIADH) can also be attributed to volume expansion. Of those, 47 (77.4%) also received cisplatin.64 On the other hand, the incidence of hypophosphatemia related to moderate dose of ifosfamide may be as low as 1%.62, Antiviral medications including cidofovir, tenofovir, and more often, adefovir can induce hypophosphatemia due to FS. Diagnosis is … In a series of 62 children who received ifosfamide 10 (16.1%) developed hypophosphatemia. Thus, it should be mostly considered as a contributing factor in patients with low serum phosphate levels.17 Nevertheless, large doses of mannitol can cause pseudohypophosphatemia by binding to the molybdate used in the colorimetric assay of phosphorus. The incidence of ifosfamide-related hypophosphatemia varies considerably. The fractional excretion of phosphate is generally in the range of 10–15%. For example, parathyroid hormone (PTH) and fibroblast growth factor-23 (FGF-23) decrease the absorption of phosphate in the proximal tubule, while 1,25-dihydroxyvitamin D3 increases tubular phosphate reabsorption. This loss of calcium can eventually cause bone disease. As mentioned above, PTH and FGF-23 increase the renal Pi losses by decreasing the activity of sodium-phosphate co-transporters.11 Hypophosphatemia associated with increased renal phosphate clearance has also been reported in patients with hypokalemia and hypomagnesemia. Acetaminophen poisoning has repeatedly been identified as cause of hypophosphatemia. What is Hyperphosphatemia? What is hyperphosphatemia? This will bring the levels of calcium and phosphate in the blood back to normal. Sleep disturban… A new study finds several medications … In fact, it has been reported that nebulized salbutamol (within 20 min) as well as theophylline result in hypophosphatemia.32,33 Apart from internal Pi redistribution, sympathomimetic agents (mainly dopamine and theophylline) can cause hypophosphatemia by increasing the urinary phosphorus excretion rate.31,34 Finally, therapeutic hypothermia (32–33°C) possibly through sympathetic activation has been implicated in the development of hypophosphatemia.35, An acute increase in hematopoietic cell production by the bone marrow is associated with phosphate uptake by the new cells, which may be of sufficient magnitude to induce hypophosphatemia. Hypophosphatemia-related to drug-treatment can be caused by several medications. Toxicity involves mainly proximal (reflecting partial or complete FS) and distal renal tubules (type I renal tubular acidosis and nephrogenic diabetes insipitus).59,60, Medications causing hypophosphatemia by inducing FS, In a series of 593 sarcoma patients on ifosfamide the incidence of nephrotoxicity was 4.6%.59 It has been reported that the ifosfamide metabolite, chloroacetaldehyde, may be responsible for this nephrotoxicity. Hypophoshatemia as a consequence of drug treatment. (A) Summary of phosphate (Pi) metabolism for a normal adult in neutral phosphate balance. Healthy kidneys adjust the levels of minerals in the blood, but kidneys that are not working properly are not always able to do this. This review aims at a thorough understanding of the underlying pathophysiological mechanisms and risk factors of drug therapy-related hypophosphatemia thus allowing prevention and effective intervention strategies. Correct nurse include in the teaching session as the cause of the current diagnosis? Shortness of breath 3. This deterioration can take place over many years, often without symptoms. Measuring the levels of phosphate in the liquid part of the blood, called plasma. In plasma, phosphate is mainly present as inorganic phosphate (Pi), and this fraction is very small (<0.2% of total phosphate).3 However, body phosphate metabolism is regulated through plasma inorganic phosphate. It is noteworthy that the incidence of antacid use in the hypophosphatemic subgroup (4 out of 21; 66%) was significantly higher than the use in the non-hypophosphatemic subgroup (2 out of 14; 14%) (P < 0.05).40, Hypophosphatamia can be caused by inappropriate phosphaturia. It is related to the formation of Pi-containing intermediates of glycolytic metabolism.20 The source of this phosphate is the Pi in the extracellular fluid; as a result, serum phosphate levels fall rapidly. Those who have had kidney failure and are having dialysis are most at risk. Phosphorus supports bones and teeth to develop and helps turn food into energy for the body to use. An X-ray may be needed if a person has symptoms of mineral and bone disorder. Kidney dialysis also removes some phosphates from the blood. The serum Pi concentration should be measured every 6 h because the response to phosphate supplementation is not predictable.8,98,99. However, these drugs also exhibit a weak carbonic anhydrase activity, which can explain their weak phosphaturic effect.49 In a series of 86 patients with congestive heart failure (New York Heart Association functional classes III–IV) who were all treated with frusemide, hypophosphatemia (defined as serum phosphorus <0.77 mmol/l) was diagnosed in 12.8% of patients.50. Shifts of extracellular phosphate into cells, Acute respiratory alkalosis (salicylate poisoning, mechanical ventilation), Administration of glucose, fructose, insulin therapy, parenteral nutrition, Catecholamine action: epinephrine, dopamine, salbutamol, xanthine derivatives, hypothermia, Rapid cellular proliferation (erythropoetin, GM-CSF therapy), 3. This is usually done by eating certain foods and avoiding others. There are three types of cholesterol: HDL or good cholesterol, LDL or bad cholesterol, and total cholesterol. Moreover, respiratory alkalosis (due to sepsis, cirrhosis or alcohol withdrawal) and hyperinsulinemia (due to administration of glucose for rehydration or refeeding) contribute to increased entry of phosphorus into the cells and hypophosphatemia.86. The incidence of adefovir-related FS and hypophosphatemia is dose-dependent. Pseudohypophoshatemia. It is rare for the acute cases to create long-standing problems as these are most commonly caused by adolescent growth spikes. Anorexia 4. Hypophosphatemia when combined with phosphate depletion can cause a variety of signs and symptoms.4,5 The manifestations are closely related to the severity and chronicity of its occurrence, with the plasma phosphate concentration usually being below 1.0 mg/dl (0.32 mmol/l) in symptomatic patients.1 It should be emphasized that serum phosphorus concentrations lower than 1 mg/dl for two or more days can lead to serious complications, such as rhabdomyolysis, respiratory failure, acute hemolytic anemia and arrhythmias.6 Of note, in a retrospective study, severe hypophosphatemia was associated with a fourfold increase in mortality.7. In a study of normal human volunteers, it took ∼3 months for the combination of low phosphorus diet and antacids to diminish serum Pi levels to 1 mg/dl.38 Thus, prolonged high-dose therapy with these agents is associated with increased risk of hypophosphatemia even in patients with end-stage renal disease, an entity usually characterized by phosphate retention.39, Finally, hypophosphatemia related to prior antacid use is not infrequently observed in patients who undergo hepatic resection. Hypophosphatemia often develops in the course of treatment with drugs used in every-day clinical practice. In the following sections, we will present relevant information on the incidence and the pathophysiology of hypophosphatemia in association with the most commonly offending drug agents (Table 1). Hypophosphatemia is a serum phosphate concentration < 2.5 mg/dL (0.81 mmol/L).

It appears that there is a correlation between the degree of hypophosphatemia and the severity of liver damage due to acetaminophen.87–89 The etiology of acetaminophen overdose-induced hypophosphatemia is multifactorial. Most people will get more than enough phosphorus from their diet, and the body is usually good at regulating levels. Consequently, a thorough understanding of the underlying pathophysiologic mechanisms of drug-induced hypophosphatemia and the associated risk factors is of vital importance. The available calcium, lanthanum, sevelamer, and iron-based drugs for treating hyperphosphatemia are associated with certain side effects. Processed foods often have phosphorus added to preserve them, and a high-protein diet may also contain more phosphorus than someone needs. Medication Summary Oral phosphate binders are used to decrease the highly efficient gastrointestinal absorption of phosphorus. Learn all about the different causes of painful ejaculation, along with associated symptoms and treatment options for this common condition. In fact, hypophosphatemia frequently develops in the course of treatment with drugs used in every-day clinical practice including diuretics and bisphosphonates. renal tubular defect) are present. However, if the cause was due to poisoning, parasites or trauma, it is vital to get your pet to a veterinarian for treatment of the underlying cause. Clinical features include muscle weakness, respiratory failure, and heart failure; seizures and coma can occur. Hypophosphataemia owing to renal losses is observed after inhibition of carbonic anhydrase with acetazolamide. Clinical features may be due to accompanying hypocalcemia and include tetany. Fatigue 2. Phosphate binds calcium, which can lead to hypocalcemia. For full access to this pdf, sign in to an existing account, or purchase an annual subscription. The doctor will ask about their medical history, discuss any symptoms, do a physical examination, and sometimes recommend a phosphate test. Calcification can make dialysis more difficult. For example, during preparing for a colonoscopy, you may take a laxative. Treatment includes medication and hospitalization. Read this article to find out the…, Health is a state of physical, mental and social well-being, not just the absence of disease or infirmity. Mild hypophosphatemia is generally asymptomatic. Hyperphosphatemia Medications. What’s the function of phosphates in the body? Nausea 5. 4. Phoslo (calcium acetate) Drug class: Phosphate Binders. Kidney disease is the most common cause of hyperphosphatemia. Hyperphosphatemia is a common laboratory finding that arises from a host of differing causes. Overview Hyperphosphatemia Drugs.

The phosphorous-containing laxative can lead to … In a series of 79 alcoholic patients admitted to the internal medicine department for causes related to alcohol abuse, 23 subjects (29.1%) exhibited hypophosphatemia.86 The underlying mechanisms involved poor dietary phosphate intake, decreased intestinal Pi absorption, transcellular shift of Pi from the extracellular fluid into cells, and increased renal Pi excretion.86, Increased gastrointestinal phosphate losses due to either use of antacids to treat recurring gastritis or diarrhea are not infrequently evident in patients who chronically abuse alcohol. Acetazolamide is the most effective phosphaturic diuretic because phosphorus reabsorption mainly occurs in the proximal tubules.3,Thiazides and indapamide can produce an increase in the renal clearance of inorganic phosphate and hypophosphatemia.46,47 The underlying mechanisms may involve a direct effect of the diuretic on distal renal tubular reabsorption of phosphate, inhibition of carbonic anhydrase as well as changes in potassium and/or magnesium homeostasis. 90 Increased intestinal absorption is generally caused by a large oral P intake 91 and a vitamin D overdose in preterm infants or an erroneous medical prescription (oral phosphate Joulie's solution instead of alkaline solution) in … Your body tries to "fix" this using a hormone called parathyroid hormone (PTH). It is known that the concurrent use of sodium 2-mercapto-ethanesulfonate (mesna), a synthetic thiol compound that detoxifies reactive ifosfamide metabolites, reduces the incidence of ifosfamide-induced hemorrhagic cystitis. The bones in their legs may bend inward or outward, which is sometimes known as renal rickets. Over the reparative phase of acidosis, however, cellular organic phosphates are resynthesized, causing extracellular Pi to move into cells, thus leading to hypophosphatemia.80,81, Metabolic acidosis (namely, alcoholic ketoacidosis) is one of the possible underlying mechanisms of alcohol-related hypophosphatemia.82 It has also been reported that sniffing of toluene can cause distal tubular acidosis and hypophosphatemia.83, Vitamin D insufficiency can lead to hypophosphatemia both by diminishing gastrointestinal phosphate absorption and by inducing hypocalcemia and secondary hyperparathyroidism, resulting in increased urinary phosphate excretion. Hypophosphatemia resulting from more than one mechanism. Internal Pi redistribution because of stimulation of glycolysis takes place in several situations: respiratory alkalosis and administration of glucose, fructose, insulin, catecholamines (epinephrine, dopamine, salbutamol), xanthine derivatives, estrogen, oral contraceptives, glucagon, total parenteral nutrition insufficiently supplemented with phosphate, as well medications that cause rapid cellular proliferation (erythropoetin, other GM-CSF (granulocyte-macrophage colony-stimulating factors).
