N2 - Background & Aims: Reduced bone mass is a common complication of inflammatory bowel disease (IBD), although the mechanisms that contribute to osteopenia are not completely understood. Tumor necrosis factor α (TNF-α) is up-regulated in patients with IBD and has detrimental effects on osteoblasts. Phex gene is expressed predominantly in osteoblasts, and its disruption results in defective bone mineralization. The aim of this study was to evaluate whether TNF-α regulates Phex gene expression thus contributing to the abnormal bone metabolism observed in IBD. Methods: Phex gene expression was evaluated in calvaria of 6-7-week-old mice administered with trinitrobenzene sulfonic acid ...

This sequence change affects codon 197 of the PHEX mRNA. It is a silent change, meaning that it does not change the encoded amino acid sequence of the PHEX protein. This variant is not present in population databases (ExAC no frequency). This variant has been observed to be de novo in an individual affected with hypophosphatemic rickets and to segregate with disease in a second affected family (PMID: 21902834, 29393334). ClinVar contains an entry for this variant (Variation ID: 438544). Experimental studies have shown that this variant disrupts mRNA splicing (PMID: 29393334). For these reasons, this variant has been classified as Pathogenic ...
Neuropathy and bone deformities, lifelong sequelae of leprosy that persist after treatment, result in significant impairment to patients and compromise their social rehabilitation. Phosphate-regulating gene with homologies to endopeptidase on the X chromosome (PHEX) is a Zn-metalloendopeptidase, which is abundantly expressed in osteoblasts and many other cell types, such as Schwann cells, and has been implicated in phosphate metabolism and X-linked rickets. Here, we demonstrate that Mycobacterium leprae ...

Neurohypophysial granule Ca2+-dependent endopeptidases have been allowed to act on synthetic polypeptides derived from the N-terminal sequence of bovine provasopressin-neurophysin, namely vasopressinyl-glycyl-lysyl-arginyl-alanylamide and vasopressinyl-glycyl-lysyl-arginyl-alanyl-methionyl-serinamide. Membrane-bound enzymes have been used at pH5.5 for 16 hr at 37 °C. Products have been identified by high-pressure liquid chromatography (HPLC) and by mass spectrometry performed on substances isolated by HPLC. With both substrates, vasopressinyl-Gly-Lys-Arg(OH) has been identified as a product confirming the Lys-Arg specificity previously observed on small peptide fluorogenic substrates. Cleavage yields, however, appear low suggesting that some factors are missing, for example a targeting action of the precursor neurophysin domain to the granule membrane. ...

Background: X-linked hypophosphatemia (XLH) are rare inheritable disorders caused by excessive renal phosphate wasting manifesting as rickets in children and osteomalacia in adults. Osteoid accumulates due to the reduced mineralization rate. Based on previous histomorphometric bone biopsy studies it the impression that XLH is a low bone turnover disease. Very little is known about the level of bone markers in XLH and the effects of conventional medical treatment with oral phosphate and alfacalcidol on bone turnover. Sclerostin is a potent inhibitor of bone formation described to be elevated in XLH by Palomo et all, 2014.. Objective and Hypotheses: The aim of this cross-sectional study was to evaluate aspects of bone turnover and sclerostin levels in treated and untreated patients with XLH using biochemical markers.. Method: In 27 XLH adults and in three age and sex matched controls per patient; markers of bone resorption (carboxyterminal cross-linked telopeptide of type 1 collagen, CTX), and ...

Dentinogenesis is a necessary prerequisite for dental tissue engineering. One of the steps for dentinogenesis is to obtain large quantities of highly purified odontoblasts. Therefore, we have undertaken an experiment applying different concentrations of beta-glycerophosphate (beta-GP) to induce the differentiation of dental pulp stem cells (DPSCs) in a long-term 28-day culture. In the meanwhile, we have studied the time-and maturation-dependent expression of matrix extracellular phosphoglycoprotein (MEPE) and that of the odontoblast-like marker-dentin sialoprotein (DSP), in order to investigate an optimized mineralized condition. Western blot results revealed that the expression of DSP became lower when accompanied by the increase of the beta-GP concentration, and there was also an influence on MEPE expression when different concentrations of beta-GP were applied. Meanwhile, the mineralized groups had an inhibitory function on the expression of MEPE as compared with the control group. Above all, ...

BACKGROUND While saturated fat intake leads to insulin resistance and nonalcoholic fatty liver, Mediterranean-like diets enriched in monounsaturated fatty acids (MUFA) may have beneficial effects. This study examined effects of MUFA on tissue-specific insulin sensitivity and energy metabolism.METHODS A randomized placebo-controlled cross-over study enrolled 16 glucose-tolerant volunteers to receive either oil (OIL, ~1.18 g/kg), rich in MUFA, or vehicle (VCL, water) on 2 occasions. Insulin sensitivity was assessed during preclamp and hyperinsulinemic-euglycemic clamp conditions. Ingestion of 2H2O/acetaminophen was combined with [6,6-2H2]glucose infusion and in vivo 13C/31P/1H/ex vivo 2H-magnet resonance spectroscopy to quantify hepatic glucose and energy fluxes.RESULTS OIL increased plasma triglycerides and oleic acid concentrations by 44% and 66% compared with VCL. Upon OIL intervention, preclamp hepatic and whole-body insulin sensitivity markedly decreased by 28% and 27%, respectively, along ...
Diagnosed in toddlers, X-linked hypophosphatemia (XLH) is the most common form of heritable rickets, in which soft bones bend and deform, and tooth abscesses develop because infections penetrate soft teeth that are not properly calcified. Researchers at McGill University and the Federal University of Sao Paulo have identified that osteopontin, a major bone and tooth substrate protein, plays a role in XLH. Their discovery may pave the way to effectively treating this rare disease.
CRYSVITA is the only FDA-approved therapy indicated for the treatment of X-linked hypophosphatemia (XLH) in adult and pediatric patients 6 months of age and older.

Results: The interassay CVs for iFGF23 and cFGF23 were 5.2% and 7.2%, respectively. Delayed processing for either 6 h at 22 °C or 24 h at 4 °C had no significant effect on either iFGF23 or cFGF23, although a nonsignificant trend toward decreased iFGF23 concentrations was observed compared with immediate processing (23% relative decline in concentrations under both delayed processing conditions). Three freeze-thaw cycles had no effect on either iFGF23 or cFGF23 concentrations. ...

X-linked dominant disorders are caused by mutations in genes on the X chromosome. Only a few disorders have this inheritance pattern, with a prime example being X-linked hypophosphatemic rickets. Males and females are both affected in these disorders, with males typically being more severely affected than females. Some X-linked dominant conditions, such as Rett syndrome, incontinentia pigmenti type 2, and Aicardi syndrome, are usually fatal in males either in utero or shortly after birth, and are therefore predominantly seen in females. Exceptions to this finding are extremely rare cases in which boys with Klinefelter syndrome (47,XXY) also inherit an X-linked dominant condition and exhibit symptoms more similar to those of a female in terms of disease severity. The chance of passing on an X-linked dominant disorder differs between men and women. The sons of a man with an X-linked dominant disorder will all be unaffected (since they receive their fathers Y chromosome), and his daughters will ...

Despite the importance of extracellular phosphate, the mechanisms and control of intestinal phosphate transport remain unclear. The present study used in vivo and in vitro methods to compare the extent of Na+- dependent versus Na+-independent phosphate transport along the rat small intestine and colon at different luminal phosphate concentrations. Na+-dependent and Na+-independent phosphate transport and genomic expression of type II (NaPi-II) and type III (PiT) transporters in young (3- week old) and adult (8- and 16-week old) animals fed a control or low phosphate diet have also been quantified. mRNA levels of Na+- dependent phosphate transporters have been analysed in the 5/6 nephrectomy model of chronic renal failure and following treatment with matrix extracellular phosphoglycoprotein (MEPE). The acute effects of altered luminal phosphate concentration on intestinal phosphate transport and renal phosphate transporter expression was also assessed. The findings confirm the jejunum to be the ...
Burosumab (INN, trade name Crysvita) known as KRN23 is a human monoclonal antibody designed for the treatment of X-linked hypophosphatemia.[1][2][3] Burosumab was approved by the FDA for its intended purpose, in patients aged 1 year and older, on 17 April 2018.[4] The FDA approval fell under both the breakthrough therapy and orphan drug designations.[4] This drug was developed by Ultragenyx and is in a collaborative license agreement with Kyowa Hakko Kirin.[5] While burosumab is effective for the treatment of X-linked hypophosphatemia, the National Institute for Health and Care Excellence in England and Wales initially raised concerns regarding the incremental cost-effectiveness of the new treatment[6] but the drug is available through a simple discount scheme.

Hypophosphataemic rickets is commonly an X linked dominant hereditary disorder associated with a renal tubular defect in phosphate transport and bone deformities. The gene causing this disorder has been mapped to Xp22.31----p21.3 by using cloned human X chromosome sequences identifying restriction fragment length polymorphisms (RFLPs) in linkage studies of affected families. The hypophosphataemic rickets gene locus (HPDR) was previously mapped distal to the X linked polymorphic locus DXS41 (99.6) but its position in relation to the distal loci DXS43 (D2) and DXS85 (782) was not established. In order to obtain a precise mapping of the disease locus in relation to these genetic loci, additional affected families informative for these X linked markers have been investigated. The combined results from the two studies have established linkage with the loci DXS41 (99.6) and DXS43 (D2); peak lod score for DXS41 (99.6) = 7.35, theta = 0.09, and peak lod score for DXS43 (D2) = 4.77, theta = 0.16.

Unless you actually have a metabolic bone disorder like hypophosphataemic rickets, you dont really know how it feels. Even if every member of your family has this syndrome, and so you experience the effects by proxy, you still cant feel it in your bones. But if youre the odd one out trying to understand how your family members feel, you can still be an important help-mate, and thats what this article is about. I want to describe how, within my family I have been coping with the chronic condition that affects us all.. The treatment for this particular kind of vitamin D resistant rickets (actually a historical misnomer, because many people affected by what is now called X linked hypophosphataemic rickets do, in fact, respond well to the active metabolite calcitriol, though processing of the native form, calciferol, is poorly regulated; another form of genetic rickets, involving the vitamin D receptor, is truly D resistant) has been pretty consistent over the past two decades. A combination ...
BACKGROUND: Recent nutrition guidelines for extremely-low-birth-weight infants (ELBWIs) recommend implementation of high initial amino acid (AA) supplementation in parenteral nutrition.. OBJECTIVE: We sought to evaluate the influence of AA intake on refeeding syndrome-like electrolyte disturbances including hypophosphatemia in ELBWIs.. STUDY DESIGN: Medical records of 142 ELBWIs were reviewed. Demographic, nutritional, outcome, and electrolyte data were compared between ELBWIs with initial low (1.5 g/kg/day) and high (3 g/kg/day) AA intake. Multivariate analysis was conducted to determine the odds ratio of hypophosphatemia with high AA intake and small-for-gestational-age (SGA) ELBWIs.. RESULTS: The incidence of hypophosphatemia and severe hypophosphatemia increased from 51% and 8% in period I to 59% and 20% in period II, respectively (p = 0.36 and , 0.01). Specifically, SGA ELBWIs showed higher incidence of hypophosphatemia than appropriate-for-gestational age (AGA) ELBWIs in period II, whereas ...
Many people with rare diseases like X-linked hypophosphatemia feel lonely and lost because so few people share their experiences. Chris Younger, who has XLH, and his wife, Liz, recorded a song about the rare disease to raise spirits and make people feel connected to a community that has their back.
But throughout her life, Jones hasnt let the disease stop her from doing the things she wanted to do. As a child, she loved dancing and kept doing it despite injuries and her mothers objections.. Shes turned that drive into a career and is now the executive director of the XLH Network, a patient advocacy group.. For the past year, Jones and her children have been taking a newly available medication called burosumab (Crysvita) that helps the body retain phosphorus. She said it has eased her muscle pain and fatigue.. I didnt realize how tired I was until I wasnt anymore, she said. I really had no idea how exhausted I was.. Her kids are only 6 and 8 right now, so Jones is hoping the drug will help prevent some of the damage associated with the disease.. XLH is caused by a mutation in an X chromosome. Men have an X and a Y chromosome, so if they have XLH, they will always pass it on to their offspring. Because women have two X chromosomes, a woman with XLH has a 50-50 chance of passing the ...
