What Are Complications of Hypophosphatemia? Clifton-Bligh RJ, Hofman MS, Duncan E et al. Very low phosphate levels can cause breathing difficulties, confusion, altered mental status, muscle weakness and muscle damage called rhabdomyolysis. Its expression is upregulated by low dietary phosphate [27] and calcitriol [28] and inhibited by niacin. Of the 19 patients with CRS without ICANS, 13 (68%) had clinical hypophosphatemia compared to 0% of patients without CRS or CRS+ICANS. Results of therapy with streptozotocin in 52 patients, Partial fanconi syndrome induced by imatinib therapy: a novel cause of urinary phosphate loss, Adverse events risk associated with regorafenib in the treatment of advanced solid tumors: meta-analysis of randomized controlled trials, Immune checkpoint inhibitor-induced Fanconi syndrome, Suramin-induced weakness from hypophosphatemia and mitochondrial myopathy. . What Are the Best PsA Treatments for You? Shaikh A, Wiisanen ME, Gunderson HD et al. Symptoms are bone pain, fractures, and growth abnormalities. Disorders of calcium, magnesium, and phosphate balance. Clinically patients present with bone pain, gait disturbances, pathological fractures, height loss and proximal muscle weakness [107]. During refeeding, insulin stimulates glycogen, fat and protein synthesis utilizing minerals, including phosphate, resulting in a precipitous decrease in serum phosphorus, potassium and Mg2+. WebCorrect pre-existing hypophosphatemia prior to initiating therapy with Injectafer. Several chemotherapeutic drugs are notable for inducing Fanconi syndrome. In malnutrition, hormonal and metabolic changes prevent protein breakdown of intracellular solutes, such as phosphate, and these become severely depleted. Oral replacement can be resumed after symptoms resolve or serum phosphate is >1.5mg/dL. pParathyroid hormone, which causes the release of phosphate from the bones and stimulates the kidney to remove more phosphate from the bodybloodstream into the urine. Aluminum- and Mg2+-based antacids can bind to both ingested and secreted phosphate in the intestine, while niacin promotes phosphate loss by reducing intestinal NaPi-2b expression [51, 52]. 20mmol=620mg); IV infusions should be given over 36h or per hospital policy. Treatment includes making changes to your diet, medications and PTH increases intestinal absorption of phosphate indirectly by increasing the production of calcitriol in the kidneys. Vulnerable patients with limited support systems may not have help with grocery shopping or preparing meals. This blockage leads to compensatory elevation of PTH during the first month of injection, which can contribute to hypophosphatemia by inhibiting the proximal tubule reabsorption of phosphorus [122]. Multiple studies have The daily requirement of phosphorus in adults is 700mg and the average Western diet consists of 20mg/kg/day of phosphorus (Figure 1) [21]. Note that phosphorus as a single atom is unstable; we introduce phosphorus into our bodies in the form of phosphate. Serum is a liquid Ways to increase phosphate levels in people with hypophosphatemia (low phosphate levels in the blood) include treating any underlying disorder that is causing it, oral phosphate replacement, and intravenous (IV) phosphate. Hypophosphatemia accompanying Burkitts lymphoma cell leukemia, Marked hypophosphatemia associated with acute myelomonocytic leukemia. Hypophosphatemia results from phosphate lost in the effluent during CRRT and can develop even if hyperphosphatemia is present at the start of therapy. XLH is caused by abnormally high levels of fibroblast growth factor 23, which trigger renal phosphate wasting. Several factors, including critical illness, nutritional status, cancer type and therapy, influence the development of hypophosphatemia. Biochemically it is characterized by hypophosphatemia, normal or low calcitriol and elevated or inappropriately normal FGF-23. WebHypophosphatemia is defined as a plasma phosphate level <2.5 mg/dl. Low blood phosphate; Phosphate - low; Hyperparathyroidism - low phosphate. PTH upregulates 1--hydroxylase enzyme expression in the kidneys, resulting in an increased calcitriol level as described below. Check serum phosphate levels prior to a repeat course of treatment in patients at risk for WebHypophosphatemia is defined in adults by a serum phosphate level below 2.5 mg/dL (0.8 mmol/L) and a severe hypophosphatemia by a serum phosphate level below 1 mg/dL (0.3 mmol/L) (); in children hypophosphatemia is defined according to age-related normal range ().Severe hypophosphatemia can induce proximal muscular weakness, respiratory Correspondence to: Biruh T.

In the setting of hypophosphatemia, fractional excretion of phosphate >5% (or 24-h excretion >100mg) is diagnostic of renal phosphate wasting [33]. Linking to and Using Content from MedlinePlus, U.S. Department of Health and Human Services, Certain medicines, including insulin, acetazolamide, foscarnet, imatinib, intravenous iron, niacin, pentamidine, sorafenib, and tenofovir, Fat malabsorption in the gastrointestinal tract, Hyperparathyroidism (overactive parathyroid gland), Anemia due to too many red blood cells being destroyed (. . Geller JL, Khosravi A, Kelly MH et al. Furthermore, hypophosphatemia might persist or even develop months after cessation of ifosfamide therapy [55]. Furthermore, multiple studies have demonstrated that severe hypophosphatemia (<1.5mg/dL) is an adverse prognostic marker in hospitalized patients with increased healthcare utilization, in-hospital stays, postoperative complications, cost and mortality and lower quality of life [58]. In addition to inadequate intake, medications and chronic diarrhea contribute to poor intestinal absorption. Specifically, phosphate depletion (serum phosphorus <1mg/dL) decreases 2,3-diphosphoglycerate levels, inhibiting oxygen release to tissues [9]. Examples of cancer therapyassociated diarrhea and hypophosphatemia include tyrosine kinase inhibitors (TKIs) and antitumor agents listed in Table 1. A 24-hour urine phosphate excretion less than 100 mg or a FEPO4 less than 5 percent indicates appropriate low renal phosphate excretion, suggesting that the Paracellular absorption is the predominant mechanismthe kinetics is linear, nonsaturable and dependent on the oral intake [25]. The Author(s) 2021. Phosphate is an essential salt and is found in every cell of the body. . . Cancer patients receiving care in the intensive care unit (ICU) are at exceptionally high risk for hypophosphatemia. Treatment to increase phosphate levels consists of: Low phosphate levels in the blood (hypophosphatemia) often do not cause any symptoms. . Hyperphosphatemia doesnt have symptoms. Free and non-protein-bound phosphate is freely filtered at the level of the glomerulus and 85% is reabsorbed in the proximal tubule through secondary active transport by type 2a and c Na+phosphate cotransporters (NaPi-2a and NaPi-2c) and Na+-dependent phosphate transporters 1 and 2 (PiT1 and PiT2) (Figure 2) [29]. Insulin increases uptake of phosphate into cells, leaving low levels in the bloodstream.9. . A postulated mechanism for this observed phosphate wasting is related to activation of rapamycin-insensitive protein complex 2 (mTORC2) and klotho expression by sirolimus [81]. The observed hypophosphatemia was attributed to possible inhibition of platelet-derived growth factor receptor (PDGFR) expressed on proximal tubular cells, with subsequent tubular dysfunction and inhibition of PDGFR expressed on osteoclasts, resulting in decreased bone resorption and secondary hyperparathyroidism [63, 75]. Phosphate is a component of our DNA-(1)'>DNA and other key molecules within the body. Similarly, spurious hypophosphatemia should be in the differential of multiple myeloma (MM) and other paraproteinemias due to paraproteins interference with the phosphate assay [49]. Kidney transplants mild hypophosphataemia often occurs in kidney transplant patients.6. Patients with cancer also suffer from depression, with negative symptoms resulting in anorexia. XLH is caused by abnormally high levels of fibroblast growth factor 23, which trigger renal phosphate wasting. It is most commonly caused by hyperparathyroidism and vitamin D deficiency. Factors that can cause hypophosphatemia are in red. Low levels can cause a Patients do not exhibit signs or symptoms of hypophosphatemia and no treatment is needed [47]. Monitor serum phosphate levels in patients at Pathophysiologic implications, clinical presentations, and treatment, Alteration of membrane deformability in hemolytic anemias, Acquired phagocyte dysfunction. Poor intake, transcellular shift, GI and renal loss or RRT can all contribute to this condition. 29630224 Bookshelf ID: NBK493172 Excerpt Phosphate is one of the most important molecular elements to normal cellular functions within the body. The symptoms of hypophosphatemia are varied depending on the level and rate of depletion and are non-specific, therefore the diagnosis is usually based on biochemical findings [ 1 ]. PiT1 and PiT2 make minor contributions to renal phosphate reabsorption. IV phosphate replacement should be considered in any symptomatic patient or severely depleted patient <1.0mg/dL and patients should be monitored closely for the development of arrhythmias during the infusion and the development of hypocalcemia and hyperkalemia. . High serum phosphorus levels cause internalization of the transporters and an increase in phosphate excretion. . Activated fibroblast growth factor receptor 3 (FGFR3) signaling is considered to be involved in XLH It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. The most common tumors causing TIO are the PMT mixed connective tissue variants [108]. Editorial team. Causes include alcohol use disorder, burns, starvation, and diuretic use. Depletion of ATP in the heart can result in depression of myocardial performance and tachyarrhythmias in patients with serum phosphate 1.5mg/dL [15]. Motzer RJ, Hutson TE, Tomczak P et al. WebNormal blood phosphorous levels are between 2.5 to 4.5 mg/dL. The remainder of phosphate excretion occurs through feces, which contain the unabsorbed phosphate in the diet and the phosphate excreted in digestive juices and enzymes [21]. Possibly related to activation of rapamycin-insensitive protein complex 2 (mTORC2) and klotho expression [, Unknown. National Library of Medicine . Vitamin D can be given in tablet or injection form, if required, and is often given with calcium supplements. Depletion of phosphate also limits adenosine triphosphate (ATP) synthesis, which is vital for multiple intracellular functions and organ systems [10, 11]. Biber J, Hernando N, Forster I et al. . Not taking enough phosphate in the diet this is uncommon as phosphate is present in nearly all foods. Hypophosphatemia is an abnormally low level of phosphate in the blood. For example, hypophosphataemia may be due to excess loss of phosphate in the urine which can, very rarely, be due to ageneticcondition. . Chong WH, Andreopoulou P, Chen CC et al. Hilfiker H, Hattenhauer O, Traebert M et al. Hypophosphatasia (HPP) is a rare genetic disorder characterized by impaired mineralization (calcification) of bones and teeth. For full access to this pdf, sign in to an existing account, or purchase an annual subscription. Hypophosphatemia can develop as a result of phosphaturic mesenchymal tumors or as a paraneoplastic phenomenon. Gupta S, Seethapathy H, Strohbehn IA et al. Monitor serum phosphate levels in patients at risk for chronic low serum phosphate. Estramustine and high-dose diethylstilbestrol diphosphate are estrogen-based medications used to treat metastatic prostate cancer and are associated with mild to moderate hypophosphatemia. . Phosphate is a type of . Postoperatively the FGF-23 level decreases rapidly, with normalization of the phosphate level by postoperative Day 5, and skeletal changes may take up to a year to normalize [113]. . All rights reserved. Kidney damage occurring in conditions such as multiple myeloma, Wilsons disease and systemic lupus erythematosus can cause high levels of phosphate to be removed from the body by the kidney.7. is also a founding member of Hi-Ethics. Check serum phosphate levels prior to a repeat course of treatment in patients at risk for low serum phosphate and in any patient who receives a second course of therapy within About 10% of inorganic phosphate is bound to plasma proteins and 5% is bound to cations such as sodium (Na+), Ca2+ and magnesium (Mg2+) [20]. Hypophosphatemia can be commonly encountered as an electrolyte imbalance and is defined as a value less than 0.8 mmol/l (2.5 mg/dl). Together, these hormones regulate how the intestine, kidneys and bones traffic phosphorus. In leukocytes, it can impair chemotaxis and phagocytosis, affecting immunity [13]. In critically ill patients receiving CRRT, phosphorus-containing dialysate, if available, should be considered and can be used to prevent the development proactively [129]. The kidneys excrete (get rid of) phosphate from our bodies. Treatment depends on the underlying cause. Symptoms Symptoms are generally consistent with the primary disease that is responsible for the hypophosphatemia, rather than any that would be related to the phosphate concentration itself.

First published: 01 June 2023 https://doi.org/10.1111/tme.12980 Read the full text PDF Tools Share Abstract Objectives This case series would like to highlight hypophosphatemia related to ferric carboxymaltose and its . Hypophosphataemic rickets a rare collection of inherited conditions that affects bones and growth.5. Despite the inclusion of phosphate in the TPN, the development of hypophosphatemia (<2.5mg/dL) is common, occurring in up to 40% of patients [115]. . Sodium bicarbonate in kidney transplant recipients: do some apples a day keep the doctor away? Problems occur because mineralization is the process by which bones and teeth take up calcium and phosphorus required for proper hardness and strength. Among hospitalized patients, hypophosphatemia (defined as serum phosphorus <2.5mg/dL) is observed in up to 5% of individuals, but the rate is much higher in patients with advanced cancer. Tataranni T, Biondi G, Cariello M et al. Call 911 for all medical emergencies. Hypophosphatemia may also be a complication of hematologic malignancies in a phenomenon called tumor genesis syndrome [90], where hypophosphatemia is caused by a shift of extracellular phosphorus into the rapidly replicating malignant cells that consume extracellular stores [91, 92]. A prospective study, Alterations of red-cell glycolytic intermediates and oxygen transport as a consequence of hypophosphatemia in patients receiving intravenous hyperalimentation, Erythrocyte 2,3-diphosphoglycerate depletion associated with hypophosphatemia detected by routine arterial blood gas analysis, Severe hypophosphatemia. It may have some role in increasing intestinal phosphate absorption through NaPi-2b overexpression, especially during dietary phosphorus deficiency [28, 41]. WebNormal Phosphate levels: 2.7 to 4.5 mg/dL (<2.7 is hypophosphatemia) Role of phosphate in the body: helps build bones/teeth and nerve/muscle function. . Hypophosphatemia was transient; however, case reports described chronic hypophosphatemia with osteomalacia in patients with chronic anemia requiring repeated IV iron infusion [118]. On the contrary, Vvitamin D, thyroxine and growth hormone all helps both the kidney and the small intestine to reabsorb phosphate. . However, some people have problems with absorbing phosphate from the diet.8. Oronsky B, Caroen S, Oronsky A et al. eMedicineHealth does not provide medical advice, diagnosis or treatment. Organic phosphorus is present with calcium (Ca2+) as hydroxyapatite in bones and teeth (85%) and intracellular in soft tissues (14%). The proposed mechanism is FCM blocking the cleavage of intact FGF-23 (iFGF-23) to inactive cleaved FGF-23 and subsequently the increased iFGF-23 level leads to phosphaturia [119]. WebHypophosphataemia is the name of a condition describing low levels of phosphate in the blood. Treating malnutrition related to cancer and cancer therapy should be part and parcel of cancer treatment. J. Clin. This usually does not cause symptoms, but it can lead to muscle weakness, loss of appetite, Jonsson KB, Zahradnik R, Larsson T et al. Medical professionals define hypophosphatemia as an adult serum phosphate level of less than 2.5 milligrams per deciliter (mg/dL). Risk factors for nephrotoxicity and hypophosphatemia include a cumulative dose of ifosfamide >60g/m2, young age and pretreatment with cisplatin. Learn more about A.D.A.M. Denosumab blocks the receptor activator of nuclear factor B ligand to decrease osteoclastic bone resorption in patients with osteoporosis and metastatic bone disease. Skim milk, if tolerated, is also an excellent source of phosphate replacement. Circulating levels of soluble klotho and FGF23 in X-linked hypophosphatemia: circadian variance, effects of treatment, and relationship to parathyroid status. Sodium phosphate injection provides the same phosphate content as potassium phosphate. Renal phosphate excretion is also increased by PTH and phosphatonins (including FGF-23 and klotho) through the downregulation of NaPi-2a. In patients with nonresectable FGF-23-secreting tumors, medical management consists of dietary phosphate and calcitriol supplementation. WebSymptoms of hypophosphatemia occur only when the phosphate level in blood becomes very low. The response to parenteral phosphate is variable and not predicted well from initial levels, but general guidance has been published from several sources (Table 3). Berman E, Nicolaides M, Maki RG et al. In general, the etiologies of hypophosphatemia in cancer can be classified by their mechanisms. Hypophosphatemia is defined as a serum phosphate of 2.5 mg/dL.It is more common in patients with alcohol use disorder and in critically unwell patients, who have The mechanism for mTOR inhibitorassociated hypophosphatemia is still not identified. Nonetheless, sirolimus, an mTOR inhibitor, has been associated with impaired proximal tubular phosphate reabsorption in kidney allograft recipients. Low levels of phosphate rarely lead to symptoms of hypophosphataemia; rather symptoms usually result from the associated condition that causes hypophosphataemia. A high serum phosphorus level increases the PTH level, which acts on PTH receptor (PTHR) 1 in the proximal tubule, causing downregulation and removal of NaPi-2a, NaPi-2c and PiT-2 channels from the brush border membrane, resulting in renal phosphate loss [36, 37]. Thrombocytopenia at the time of infusion was significantly associated with the . is among the first to achieve this important distinction for online health information and services. . Lipton A, Fizazi K, Stopeck AT et al. . Once spurious hypophosphatemia has been excluded, the diagnostic approach outlined in Figure 3 can be applied. Together, these hormones regulate how the intestine, kidneys and bones traffic phosphate. In Similarly, patients after allogeneic stem cell transplants can develop hypophosphatemia during hematopoietic reconstitution [93]. WebHypophosphataemia is the name of a condition describing low levels of phosphate in the blood. Clinical presentation: hypophosphatemia with paradoxically low 1,25-OH-vitamin D levels (this is paradoxical, because normally hypophosphatemia would Webhypophosphatemia resolved within three months. Besides providing structure for the body, forming the extracellular matrix of bone and teeth, phosphorus is also a significant intracellular anion and an essential component of nucleic acids, cell membranes, receptor signaling proteins, enzymes, acid buffering and energy metabolism. Filipski KK, Loos WJ, Verweij J et al. Phosphate levels normalized when transporting the test tube to the laboratory on ice [50]. Fifty-one percent of patients reported developing hypophosphatemia (<2mg/dL); however, no further evaluation was performed to identify the etiology. Diagnostic approach to hypophosphatemia. Moreover, pseudohypophosphatemia was observed in acute leukemia patients with extreme hyperleukocytosis and was attributed to the increased metabolic activity of the leukemic cells in the testing tube. Schwarz C, Bhmig GA, Steininger R et al. Potential long-term consequences of phosphate replacement are extrapolated from other phosphate-wasting diseases, including nephrocalcinosis, chronic kidney disease and secondary hyperparathyroidism [132]. Baldazzi V, Tassi R, Lapini A et al. Hypophosphatemia is a common finding in cancer patients treated with mTOR inhibitors. FGF-23, along with coreceptor klotho, acts on the proximal tubule to decrease phosphate reabsorption by downregulating NaPi-2a and NaPi-2c [42]. X-linked hypophosphatemic rickets (XLH) is characterized by hypo-mineralization of the bone due to hypophosphatemia. Patients with GI tumors or malignant ascites can experience early satiety, nausea and vomiting. Complications of low phosphate levels in the blood (hypophosphatemia) depend on how severe and/or chronic the depletion is and may include: 2023 WebMD LLC. . Summary Hypophosphatemia is a low level of phosphate in the blood. WebHypophosphatemic rickets is a genetic disorder characterized by hypophosphatemia, defective intestinal absorption of calcium, and rickets or osteomalacia unresponsive to vitamin D. It is usually hereditary. Phosphate given through a drip can sometimes cause low blood calcium levels (hypocalcaemia) and related problems, and therefore should only be given if absolutely necessary. Case Presentation. In the case of antacids or diarrhea, for example, the agent can be discontinued and the diarrhea managed. Segawa H, Kaneko I, Yamanaka S et al. . . What Health Problems Can Obesity Lead To? Phosphate is a component of our DNA - (1)'>DNA and other key molecules within the body. They are usually small in size and may be located in any soft tissue or bone site throughout the body. . . Nonetheless, Fanconi syndrome is considered a rare complication. Hypophosphatemia associated with chronic diarrhea is typically mild or moderate in severity. follows rigorous standards of quality and accountability. Marvin VA, Brown D, Portlock J et al. This dysfunction resolved rapidly after the completion of chemotherapy [61]. Hypophosphataemia occurs either when not enough phosphate is absorbed from the stomach intestine into the bloodstream or when too much phosphate is passed in the urine, leaving low levels of phosphate in the blood. . Phosphate excretion is also increased by glucocorticoids [31] and estrogen [32].

Glaspy JA, Lim-Watson MZ, Libre MA et al. Hypophosphataemia is usually mild and can often be controlled by diet or lifestyle changes. Among other serious effects, hypophosphatemia can impair tissue oxygenation and can cause hemolysis, leukocyte and platelet dysfunction, encephalopathy, seizures, arrhythmias, cardiomyopathy, rhabdomyolysis and coma. Fanconi syndrome occurs primarily in patients with lymphoma and monoclonal gammopathy. A.D.A.M. The associated hypophosphatemia with IV bisphosphonates is usually mild, transient and attributed to the elevation of PTH during the abrupt decrease in serum Ca2+. Cancer therapies associated with hypophosphatemia, Indirectly related to hypomagnesemia and hypocalcemia with associated vitamin D resistance and PTH secretion [5660], Suramin, amrubicin, pamidronate, nivolumab, ipilimumab, imatinib, vemurafenib, capecitabine in combination with irinotecan and bevacizumab, Inhibition of PDGF receptor expressed in bone and proximal tubular cells [63,75,76], Vitamin D deficiency associated with chronic diarrhea [77], Unknown. The serum phosphorus level is homeostatically regulated and maintained in a narrow range between 3.0 and 4.5mg/dL (0.971.45mmol/L) by three principle hormones: parathyroid hormone (PTH), phosphatonins [mainly fibroblast growth factor 23 (FGF-23) and klotho] and 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3] (calcitriol). Familial hypophosphatemia is a term that describes a group of rare inherited disorders characterized by impaired kidney conservation of phosphate and in some cases, altered vitamin D metabolism. Phosphate is an electrolyte , a type of mineral that is found in your blood, urine, tissues, About 520% of filtered phosphate (13mg/kg/day) is eventually excreted in the urine (Figure 1). In cases of severe or refractory hypophosphatemia, the involvement of nephrology should be considered. In a recently published systematic review, hypophosphatemia (<2.5mg/dL) was observed in up to 92% of patients with iron deficiency anemia treated with third-generation IV iron preparation, specifically ferric carboxymaltose (FCM). Phosphate is an electrolyte (mineral) that works with calcium to help build bones. Izzedine H, Launay-Vacher V, Isnard-Bagnis C et al. Another possible explanation for phosphate wasting is related to the concurrent hypomagnesemia and hypocalcemia that contribute to vitamin D resistance and stimulate PTH secretion [58, 59]. Hypophosphatemia is a common disorder in cancer patients that can result from malignancy itself or from its therapy. Hypophosphatemic rickets is a form of rickets that is characterized by low serum phosphate levels and resistance to treatment with ultraviolet radiation or vitamin D ingestion.
