Active clinical trials for "Hypophosphatemia"

Development of a new mass spectrometry-based biomarker for the early and sensitive diagnosis of Cystinosis disease from the blood

This study aims to provide Health-related Quality of Life (HRQoL) data from children and adolescents with growing skeletons in the United Kingdom (UK), including those treated with burosumab or alternative XLH treatment, as part of an updated submission to the SMC in early 2023. This study will utilise data from a subset of UK sites already within the XLH Registry (including participating Scottish sites) and collect additional HRQoL data within these sites (that are otherwise not included in the wider XLH Registry protocol). The HRQoL data will enable the calculation of HRQoL to derive the HRQoL utility estimates in children and adolescents with growing skeletons for the RSS health states, hence addressing an area of uncertainty.

Retrospective study in the surgical intensive care unit of the Brest Teaching Hospital (France) during a 6-months period (January 2015 -May 2015) to study the independent association between hypophosphatemia and 28-day infection.

The current study aimed to determine the incidence of hypophosphatemia (HP) among severe sepsis/septic shock patients admitted to ICU and its impact on morbidity and mortality rates of these patients, and to evaluate the impact of phosphorous supplemental therapy (PST) on such outcomes.Thus, this study will hypothesize that diagnosis and management of HP may be advantageous for reduction of morbidity and mortality rates of septic patients admitted to ICU.

The point prevalence survey aims at defining the until now unknown real prevalence of hypophosphatemia (defined as blood phosphate value < 0.8 mmol/l) in international critical care settings

This study aimed to characterize foot pathologies using X-rays and clinical examination and assess related outcome scores in adolescents and adults with X-linked Hypophophatemia

Patients with severe sepsis/septic shock complicated by hypophosphatemia are at high risk of developing morbidities other than that underlying sepsis and more vulnerable to higher mortality rate. Thus, the current study hypothesized that diagnosis and management of hypophosphatemia may be advantageous for reduction of morbidity and mortality rates of septic patients admitted to ICU

Retrospective study in the 3 intensive care units of the Brest Teaching Hospital (France) during a 18-months period (June 2014 -December 2015) to study the independent association between hypophosphatemia and 90-day mortality.

The aim of the study are: 1) To evaluate the occurrence of acid-base alterations and the incidence of hypophosphatemia during different modalities of Renal Replacement Terapy (RRT) in critically ill patients [CVVH, CVVHDF and SLED (Sustained Low-Efficiency Dialysis)] by using a simplified Regional Citrate Anticoagulation (RCA) protocol combined with the adoption of a phosphate-containing solution as dialysate and/or replacement fluid; 2) To optimize the infusion rates of different solutions adopted, including citrate, in order to obtain an appropriate electrolyte and buffer supply. The final aim of this approach will be to reduce the need for frequent monitoring of acid-base status and electrolytes (with special regard to ionized calcium levels), and to avoid the need for frequent adjustments of RCA-RRT parameters (infusion rate of different solutions, electrolytes supplementation in the course of RRT). This approach could allow to simplify anticoagulation protocols with citrate, in order to minimize potential concerns hampering a wider diffusion of RCA in daily practice.

Fibroblast froth factors (FGFs) are humoral factors identified by their ability to stimulate cell proliferation1. They play different roles in the regulation of cell proliferation, differentiation and function. Most FGF family members act as paracrine factors. But FGF19(FGF19) subfamily members, including FGF19, 21, and 23, work as endocrine factors to regulate bile acid, carbohydrate and phosphate metabolism2. Of these, FGF23 plays an important role in phosphate and bone metabolism3. FGF23 gene encodes 251 amino acids, including a 24-amino acid signal peptide4. The secreted FGF23 is a protein consisted of 227 amino acids. It works by binding to a Klotho-FGF receptor 1c (FGF1c) complex5. FGF suppresses the expression of type 2a and 2c sodium-phosphate cotransporters, which mediate phosphate reabsorption in proximal tubules.6 FGF23 decreases 25-hydroxyvitamin D-1α-hydroxylase expression and enhances 25-hydroxyvitamin D-24-hydroxylase expression6. Therefore, FGF23 reduces serum 1,25-dihydroxyvitamin D〔1,25(OH)2D〕, which stimulates intestinal calcium and phosphate absorption. FGF23 decreases serum phosphate through the above mechanisms FGF23 over-expression might result in hypophosphatemic rickets and osteomalacia. Tumor induced osteomalacia (TIO) is a paraneoplastic syndrome usually caused by benign phosphaturic mesenchymal tumors. Symptoms are nonspecific, such as general weakness, fatigue, and bone pain. Sometimes fracture may occurs. The responsible tumors are sometimes small and difficult to detect. Tumors secrete FGF23. FGF23 reduced phosphate reabsorption in the proximal tubules and decrease 1,25(OH)2D levels, which result in hypophosphatemia and then osteomalacia. The investigators would like to observe the changes of FGF23 in patients who receive operation or medical treatment and hope this will benefit future treatment.
