Filter by:The goal of this study is to find out if the use of ultrasound pictures of bones can spot changes in the growth areas of children with rickets, a condition that affects how bones harden. Researchers want to see if these ultrasound pictures can help tell the difference between children who have rickets and those who don't.
The objective of this post-marketing surveillance (PMS) study is to assess the safety and effectiveness of CRYSVITA injection 10, 20, and 30mg, equivalent to in routine clinical settings
Patients with hypovitaminosis D are randomized into three arms of treatment: Group A: Calcifediol 0,266mg each month Group B: Cholecalciferol 25000UI each 15 days Group C: Calcifediol 4 drops per day. Serum levels of vitamin D are dosed after one month of treatment
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.
The primary purpose of Study INZ701-106 (The ENERGY 3 Study) is to assess the efficacy and safety of INZ-701 in children with ENPP1 Deficiency.
The primary purpose of Study INZ701-104 (the ENERGY study) is to assess the safety and tolerability of INZ-701 in infants with ENPP1 Deficiency.
The purpose of this study is to assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of multiple ascending doses of INZ-701, an ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) enzyme replacement therapy, for the treatment of ENPP1 Deficiency. The goal of the study is to identify a dose regimen for further clinical development in the treatment of ENPP1 Deficiency.
Generalized arterial calcification of infancy (GACI) is an ultra-rare disorder with an estimated birth prevalence of around 1 in 400,000.1 GACI is generally fatal before birth or within the first six months after birth. The cause of death is frequently myocardial infarction or stroke. GACI is strongly associated with inactivating mutations in ectonucleotide pyrophosphate/ phosphodiesterase 1 (ENPP1). Many patients with GACI, including some without an ENPP1 mutation also present with mutations in adenosine triphosphate binding cassette transporter protein subfamily C member 6 (ABCC6). Autosomal recessive hypophosphatemic rickets type 2 (ARHR2) and pseudoxanthoma elasticum (PXE) are believed to be closely related to GACI. ARHR2 is caused by mutations in the ENPP1 gene and PXE is caused by mutations in the ABCC6 gene, with both being observed among patients with GACI. The natural history of GACI and in particular its long term morbidity and mortality are poorly understood. The primary objective of this study is to characterize overall survival among patients with GACI, over time from birth.
Children and adults with XLH recruited will be treated with calcitriol alone (without phosphate supplementation) for one year, during which the calcitriol dose will be escalated during the first 3 months of therapy. The investigators hypothesize that treatment of adults and children with XLH alone will improve serum phosphate levels and skeletal mineralization without causing an increase in kidney calcifications. The study will also examine if calcitriol therapy will improve growth in children.
On a daily basis many (prematurely born) newborn are subjected to different urine collecting techniques to study biochemical abnormalities. Neonatology nurses and pediatricians are looking for a better and less invasive manner to collect urine in these vulnerable patients. We hypothesise that the urine collecting device as presented in this protocol is less invasive and has good functional abilities to collect urine in these newborns Objective of the study: Clinical feasibility of the urine collection device, indicated by staff and parents. Study design: The study will be an open label, clinical feasibility study, of the urine collection device. During a period of 6 months, 30 feasibility tests will be performed. Study population: Prematurely born newborns, admitted to the neonatology unit of the department of pediatrics at Rijnstate Hospital Arnhem.
