Filter by:Anaemia (low haemoglobin levels) can develop in a number of conditions, including chronic kidney disease (CKD) and intestinal conditions (e.g. inflammatory bowel disease, intestinal failure). Intravenous iron can be given to patients with these conditions to help correct their aneaemia. However, intravenous iron has been associated with the development of low phosphate levels - hypophophosphataemia. The aim of this study is to determine potential causes of hypophosphataemia following administration of intravenous iron.
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
In this prospective longitudinal cohort study we studied the efficacy and safety of burosumab in real-clinical practice for <13- and >13-years old children affected with X-linked hypophosphatemia. 57 children with XLH were switched from conventional treatment to burosumab. After 12 months we assessed the efficacy and safety of treatment with burosumab on the whole cohort and separately on the cohort of >13-years old adolescents.
Hereditary hypophosphatemia (XLH) is a rare, inherited disease. Loss-of-function mutation in the phosphate regulating gene with homologies to endopeptidases on the X-chromosome (PHEX) results in excess fibroblast growth factor 23 (FGF23) production and manifests as rickets in children and osteomalacia in adults. This study aims to characterize and measure pain, quality of life, muscle function, body composition, arterial stiffness, bone mineral density, geometry and microarchitecture in patients with XLH compared to age and gender-matched controls.
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
A Phase 1/2, Open-label, Multicenter, Non-randomized Study to Assess the Safety, Tolerability, Pharmacokinetics and Efficacy of Burosumab in Paediatric Patients from Birth to Less than 1 Year of Age with X-linked Hypophosphatemia (XLH)
Patients with X-linked hypophosphatemia (XLH) often report symptoms of fatigue and weakness particularly after exertion, in addition to their skeletal complaints. In previous trials using KRN23 (same drug as burosumab/Crysvita®), patients report these symptoms improve. The investigators wish to test this hypothesis directly by measuring muscle energy when patients begin treatment with Crysvita® for the first time.
There is limited empirical data documenting disease progression and impact on quality of life for patients with X-linked hypophosphatemia (XLH). This study seeks to investigate the impact of XLH in adults living in the UK retrospectively and prospectively over a 12 month period, using qualitative interviews, SEIQoL-DW, EQ-5D-5L, SF36 quality of life tools. XLH is a rare, genetic, chronically debilitating and deforming condition (www.nice.org.uk/guidance/HST8). XLH is characterised by renal phosphate wasting, hypophosphatemia and defective bone mineralisation. The incidence of XLH is reported to be between 1:20,000 and 1:25,000 live births. In the UK, it is estimated that there are around 250 paediatric XLH patients and around 2,500 adult XLH patients (Delmestri,et al [Unpublished report]2018). The clinical phenotype of XLH is varied amongst patients, even among affected members of the same family. This can range from no signs or symptoms, slow growth in children, short stature, bone abnormalities that can affect movement and result in pain, bowed legs and knocked knees (where lower legs are positioned at an outward angle), tooth abscesses and excessive dental caries and hearing loss (adult patients only). This study will recruit 36 adults living with XLH, who are aged 28 years or over and living in the UK. The study will be advertised by the Sponsor and funder Medialis Ltd and via the patient organisation Metabolic Support UK. All study activities will take place via tele-visits and online questionnaires. The study will last approximately 2 years, allowing for one-year recruitment and a further 12 months to conduct all study visits.
Burosumab (also known as the drug, Crysvita®) is a fully human immunoglobulin G1 (IgG1) monoclonal antibody (mAb) that binds to and inhibits the activity of fibroblast growth factor 23 (FGF23), leading to an increase in serum phosphorus levels. This drug is already approved for use in patients with X-linked hypophosphatemia (XLH), but not for Cutaneous Skeletal Hypophosphatemia Syndrome (CSHS). It is hypothesized that burosumab may provide clinical benefit to a patient with CSHS due to the common underlying feature in this patient and in patients with XLH - abnormally elevated FGF23 in the context of low age -adjusted serum phosphorous levels.
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.
