Filter by:The primary objective of the study is to compare the incidence of hypophosphatemia in RYGB patients treated with intravenous (IV) single dose of iron isomaltoside (Monofer®) or ferric carboxymaltose (Ferinject®).
The overall aim of the study is to improve understanding of refeeding syndrome (RFS) in patients admitted to the intensive care unit (ICU) using metabolomics. Patients are included as part of a prospective multicenter observational study on phosphate disorders in the ICU. Blood samples are collected day 1-7 of ICU stay. Samples from patients who develop refeeding hypophosphatemia and matched controls without hypophosphatemia are analysed for metabolomics and proteomics. Untargeted analyses will be performed to identify the affected metabolic pathways. The investigators will also perform AUROC analyses to identify potential biomarkers for early detection of RFS.
The aim of this study is to generate evidence regarding hypophosphatemia after iron infusion in lung transplant recipients in context of anemia and/or iron deficiency.
Iron deficiency anemia (IDA) is a very common health problem during pregnancy and intravenous (IV) iron substitution has become part of routine management. Recent studies have raised concerns about association of IV iron infusion and development of secondary transitory hypophosphatemia (HP) in adults including pregnant women. The study aimed to evaluate the impact of IV iron administration during pregnancy on newborn's phosphatemia. The investigators conducted a prospective, single-center, observational study in the Geneva University Hospitals (HUG), from September 2022 to March 2023. Pregnant women treated either with IV iron or with oral iron during pregnancy were included. At delivery, a maternal blood sample to assess hemoglobin, hematocrit, ferritin, phosphate and calcium and an umbilical cord blood sample to assess levels of phosphate and calcium were collected. Difference in demographics and clinical characteristics between the two groups were explored using univariate analyses. Multivariate analyses were performed to test the contribution of IV iron substitution on cord blood phosphatemia and calcemia, considering potential confounding factors. Neonatal HP was defined as a phosphate level lower than 1.3 mmol/L.
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
The goal of this National Registry is to is to collect information from patients with rare kidney diseases, so that it that can be used for research. The purpose of this research is to: - Develop Clinical Guidelines for specific rare kidney diseases. These are written recommendations on how to diagnose and treat a medical condition. - Audit treatments and outcomes. An audit makes checks to see if what should be done is being done and asks if it could be done better. - Further the development of future treatments. Participants will be invited to participate on clinical trials and other studies. The registry has the capacity to feedback relevant information to patients and in conjunction with Patient Knows Best (Home - Patients Know Best), allows patients to provide information themselves, including their own reported quality of life and outcome measures.
This study will address two specific research questions simultaneously: 1. validation of the GastroIntestinal (GI) Dysfunction score (GIDS). 2. description of epidemiology, risk factors, and management of phosphate disorders. The aim is to recruit 20 ICUs and 1500 ICU patients. Sites will recruit all consecutive adult patients to a maximum of 120 patients or a maximum recruitment period of 8 weeks, whichever comes first. Daily data collection on gastrointestinal signs and symptoms as well as phosphate values and management will be collected during ICU stay for maximum of 7 days. 28 and 90 day mortality and days free of organ support will be the main outcomes. Secondary outcomes include prevalence of hypo- and hyperphosphatemia and description of their management.
Newborn screening (NBS) is a global initiative of systematic testing at birth to identify babies with pre-defined severe but treatable conditions. With a simple blood test, rare genetic conditions can be easily detected, and the early start of transformative treatment will help avoid severe disabilities and increase the quality of life. Baby Detect Project is an innovative NBS program using a panel of target sequencing that aims to identify 126 treatable severe early onset genetic diseases at birth caused by 361 genes. The list of diseases has been established in close collaboration with the Paediatricians of the University Hospital in Liege. The investigators use dedicated dried blood spots collected between the first day and 28 days of life of babies, after a consent sign by parents.
Background: Fibrous dysplasia (FD) is a disorder that affects bone growth. Affected bone tissue is weakened, and people with FD are prone to deformities, fractures, and other problems. People with FD may also have low blood phosphate levels. This can make bones even weaker. Better treatments are needed. Objective: To test a study drug (burosumab) in people with FD who have low blood phosphate levels. Eligibility: People aged 1 year or older who have FD and low blood phosphate levels. Design: Participants will visit the NIH 3 times in 48 weeks. Each visit will last 5 to 7 days. Participants will self-inject burosumab under the skin in their belly, upper arm, or thigh. They (or a caregiver) will do this at home 1 or 2 times a month. They will be trained in person on how to inject the drug. Home injections will be guided via telehealth. During NIH visits, participants will have a physical exam with blood and urine tests. They will have x-rays of different parts of their body. They will have a radioactive tracer injected into their vein; then they will have a bone scan. They will have tests to assess their strength, walking, and movement. They will complete questionnaires about their pain, mobility, and fatigue levels. Adult participants may have bone biopsies. These will be done under anesthesia with sedation. Small samples of FD-affected bone will be removed for study. Between NIH visits, participants will go to a local laboratory for blood and urine tests. Child participants will have an additional follow-up visit 2 weeks after the final NIH visit.
An observational, prospective, mixed-methods study involving the integration of quantitative and qualitative data exploring the lived experience of burosumab-treated adolescents with XLH at the end of skeletal growth.
