BACKGROUND AND OBJECTIVES: Hypophosphatemia is common in the first year after kidney transplantation, but its clinical implications are unclear. We investigated the relationship between the severity of post-transplant hypophosphatemia and mortality or death-censored graft failure in a large cohort of renal transplant recipients with long-term follow-up. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We performed a longitudinal cohort study in 957 renal transplant recipients who were transplanted between 1993 and 2008 at a single center...

BACKGROUND: The American Society for Parenteral and Enteral Nutrition Adult Nutrition Support Core Curriculum describes clinical conditions that warrant cautious use of parenteral nutrition (CCWCPN). The Core Curriculum authors acknowledge there is no evidence for specific criteria suggested for the clinical conditions. Consequently, the purpose of this study was to determine the impact of a baseline CCWCPN on the development of subsequent metabolic complications in patients receiving parenteral nutrition (PN)...

PURPOSE: Glucose (Glu) and maltitol (Mal) ingestion affect calciuria and phosphaturia. Renal phosphate leak involving hypophosphatemia is thought to be a mechanism. Inter-race differences in carbohydrate metabolism are known. We investigated the effects of Glu and Mal ingestion on glycaemia and phosphatemia in subjects from two race groups to better understand potential implications for nephrolithiasis. METHODS: Healthy black (B) (n = 8) and white (W) (n = 8) males followed a self-selected standardized diet for 7 days and a strictly controlled standardized diet on Day 8...

BACKGROUND: Blood phosphate levels are vulnerable to fluctuations and changes in phosphate levels are often neglected. The aim of this study was to evaluate whether deviations in phosphate levels correlate to higher 180-day overall mortality or morbidity. METHODS: Four thousand six hundred fifty-six patients with 19,467 phosphate values treated at the adult intensive care unit at Skåne University Hospital, Lund, Sweden during 2006-2014 were retrospectively divided into a control group and 3 study groups: hypophosphatemia, hyperphosphatemia, and a mixed group showing both hypo/hyperphosphatemia...

BACKGROUND: Mast cells are present in the airways of patients who have severe asthma despite glucocorticoid treatment; these cells are associated with disease characteristics including poor quality of life and inadequate asthma control. Stem cell factor and its receptor, KIT, are central to mast-cell homeostasis. We conducted a proof-of-principle trial to evaluate the effect of imatinib, a KIT inhibitor, on airway hyperresponsiveness, a physiological marker of severe asthma, as well as on airway mast-cell numbers and activation in patients with severe asthma...

Idiopathic Fanconi syndrome (FS) is characterized by a generalized dysfunction of the renal proximal tubules. Patients with FS often exhibit growth retardation due to complex factors, such as hypophosphatemia, metabolic acidosis, disturbed vitamin D metabolism and hypokalemia. To date, one FS patient has been reported to exhibit growth failure due to growth hormone deficiency (GHD), but the long-term clinical course of recombinant human GH (rhGH) therapy has not been reported. At 10 months of age, the patient was admitted to our hospital due to growth failure...

Serum calcitriol [1,25(OH)2D] levels are low normal in the presence of hypophosphatemia in X-linked dominant hypophosphatemic rickets (XLH) due to elevated serum fibroblast growth factor 23 (FGF23) levels. We report a peculiar finding of markedly elevated serum 1,25(OH)2D levels in a patient with XLH complicated by autosomal dominant polycystic kidney disease (ADPKD) and retinitis pigmentosa (RP). She was diagnosed with XLH, ADPKD and RP at the age of 5, 13 and 15 years, respectively. After the diagnosis of ADPKD, the 1,25(OH)2D levels increased up to 282 pg/mL treated with a pharmacological dose of 1αOHD3 (1αOHD3)...

Secondary hyperparathyroidism is often associated with end stage renal disease; even after renal transplantation, hyperparathyroidism may persist, and is responsible for hypercalcemia, hypophosphatemia and elevated parathyroid hormone (iPTH) levels. Parathyroid hyperplasia is frequently associated with persistent hyperparathyroidism, and may require a surgical treatment. Here, we report hyperparathyroidism along with parathyroid hyperplasia in a 7-year-old child, which persisted after renal transplant. Calcitonin and pamidronate failed to decrease serum calcium levels; clodronate was also inefficient...

X-linked hypophosphatemia (XLH) is a hereditary metabolic disease caused by the loss of phosphate through the renal tubules into the urine, and an associated decrease in serum calcium and potassium phosphate. Its dental features include spontaneous dental abscesses that occur in the absence of trauma or dental caries. The aim of this case report was to describe the dental problems of XLH patients and to evaluate limitations in their treatment. A 14 year old male and a 38 year old female with XLH were referred to the Department of Conservative Dentistry for endodontic treatment...

Bone deformities and fractures are common consequences of renal osteodystrophy in the dialysis population. Persistent hypophosphatemia may be observed with more frequent home hemodialysis regimens, but the specific effects on the skeleton are unknown. We present a patient with end-stage renal disease treated with frequent home hemodialysis who developed severe bone pain and multiple fractures, including a hip fracture and a tibia-fibula fracture complicated by nonunion, rendering her nonambulatory and wheelchair bound for more than a year...

We report a 16-year-old girl who was diagnosed with acute leukaemia and a marked leucocytosis >200 × 10(9)/L. She presented with marked hypophosphatemia, hypokalemia, acute renal failure and acute respiratory failure. These electrolytes disturbances may indicate rapid tumour genesis. These ominous findings required urgent treatment to halt the crises of rapid leukemic cell proliferation. CONCLUSION: Mark hypophosphatemia and hypokalemia may be presenting electrolyte abnormalities in a patient with acute leukaemia, and these may be indicators of aggressive tumour genesis...

SUMMARY: Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome characterized by renal phosphate wasting leading to hypophosphatemia due to excessive actions of fibroblast growth factor 23 (FGF23) produced by the tumors. Although the best way of curing TIO is complete resection, it is usually difficult to detect the culprit tumors by general radiological modalities owing to the size and location of the tumors. We report a case of TIO in which the identification of the tumor by conventional imaging studies was difficult...

Osmotic demyelination syndrome is classically associated with rapid correction of hyponatremia. However, it can occur in normonatremic patients with other electrolyte abnormalities. One must suspect osmotic demyelination syndrome in susceptible patients with other electrolyte abnormalities like hypokalemia and hypophosphatemia.

In a 68-year-old man on maintenance hemodialysis (HD), severe anemia was detected. Bone marrow biopsy was performed for investigation of pancytopenia and pathological examination revealed adenocarcinoma of the prostate. Prostate specific antigen (PSA) was 574 ng/mL. After androgen deprivation therapy was initiated, PSA decreased to 13.7 ng/mL. But subsequent elevation of PSA and pain due to bone metastases were recognized. Denosumab (120 mg) was administered. Although improvement of bone pain was observed, severe hypocalcemia occurred...

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome in which unregulated hypersecretion of fibroblast growth factor 23 (FGF23) by phosphaturic mesenchymal tumors (PMT) causes renal phosphate wasting, hypophosphatemia, and osteomalacia. The resulting mineral homeostasis abnormalities and skeletal manifestations can be reversed with surgical resection of the tumor. Unfortunately, PMTs are often difficult to locate, and medical treatment with oral phosphate and vitamin D analogues is either insufficient to manage the disease or not tolerated...
