Active clinical trials for "Bone Diseases"

In summary, the investigators want to investigate whether UTE sequences are capable to replace imaging techniques involving ionizing radiation for bone imaging in the future. This would improve patient care greatly and might reduce medical imaging associated cancer risk drastically from an epidemiological standpoint. This field of research can be considered cutting-edge. The investigators determine this study promising to provide substantial generalizable knowledge and hope that this study results will improve patient care worldwide considerably.

Weight-reducing obesity surgery (OS) generally gives good results but complications are common; e.g. impaired weight loss, weight regain, bowel pain, diarrhea, vitamin/mineral deficiency, osteoporosis and impaired dental health. The BASUN study is a prospective 10-year comparison of 1000 surgically and 400 conventionally treated individuals regarding adverse side-effects, risk factors for complications and poor outcome.

Diseases of bone associated with ageing, including osteoporosis (OP) and osteoarthritis (OA), reduce bone mass, bone strength and joint integrity. Current non-surgical approaches are limited to pharmaceutical agents that are not disease modifying and have poor patient tolerability due to side effect profiles. Developing a fundamental understanding of cellular bone homeostasis, including how key cell types affect tissue health, and offering novel therapeutic targets for prevention of bone disease is therefore essential. This is the focus of OSTEOMICS. A number of factors have been linked to increased risk of bone disease, including genetic predisposition, diet, smoking, ageing, autoimmune disorders and endocrine disorders. In our study, we will recruit patients undergoing elective and non-elective orthopaedic surgery and obtain surgical bone waste for analysis. This will capture a cohort of patients with bone disorders like OP and OA, in addition to patients without overt clinical bone disease. We will study the relationship between the molecular biology of bone cells, bone structure, genetics (DNA) and environmental factors with the aim of identifying and validating novel therapeutic targets. We will leverage modern single cell technologies to understand the diversity of cell types found in bone. These technologies have now led to the characterisation of virtually every tissue in the body, however bone and bone-adjacent tissues are massively underrepresented due to the anatomical location and underlying technical challenges. Early protocols to demineralise bone and perform single cell profiling have now been developed. We will systematically scale up these efforts to observe how genetic variation at the population level leads to alterations in bone structure and quality. Over the next 10 years, we will generate data to comprehensively characterise bone across health and disease, use machine learning to drive analysis, and experimentally validate hypotheses - which will ultimately contribute to developing the next generation of therapeutic agents.

Poor bone health is a well-recognized but poorly understood complication in children with intestinal failure (IF) who are dependent on parenteral nutrition (PN). Previously, we showed that children with IF have decreased bone turnover markers. It is currently unknown if optimization of parenteral nutrition is related to improved bone turnover markers. Serum concentrations of bone markers (osteocalcin, bone-specific alkaline phosphatase and c-telopeptide) will be measured in 30 IF patients treated at a multidisciplinary intestinal rehabilitation and home PN program at the Hospital for Sick Children and compared to bone markers in 30 age- and sex-matched healthy controls.

Objective: To establish a study cohort and follow up of patients with CKD in our hospital, and evaluate the status of integrated CKD diagnosis and treatment according to guidelines in the real world, as well as the clinical prognosis of patients with different stratification. Methods: By establishing a cohort of 1000 patients with CKD and conducting long-term follow-up, integrated diagnosis and treatment for CKD was performed, namely: Regular monitoring, control of blood pressure, blood glucose, blood lipid, correction of anemia, minerals - bone metabolic abnormalities, malnutrition, acid and alkali, and electrolyte disorder, diet and exercise, such as the guidance of integrated management, non intrusive, observational studies, prospective cohort were analyzed retrospectively, describe the implementation of the integration of diagnosis and treatment, chronic kidney disease (CKD) Stratified analysis and risk factor analysis were performed for cardiovascular disease and other main endpoint events, so as to objectively reflect the status of integrated treatment of CKD and provide data support for continuous quality improvement of CKD diagnosis and treatment and improvement of clinical prognosis of patients.

It is a randomized controlled trial in which 100 non diabetic chronic kidney disease (CKD) patient is being participated. Their estimated glomerular filtration rate (eGFR) between 25-75 ml/min/1.73 m2. Participants will be randomized into two groups: Study group: includes 50 patients, they will receive Sodium glucose co-transporter 2 inhibitor (SGLT2i) as add on drug, Dapagliflozin 10 mg will be used once daily with or without food. Control group: includes 50 patients, they will receive placebo their medication. The investigators will follow up all patients for 12 months and compare their results. This study aims to: Assess SGLT2i role in delaying the progression of ongoing chronic kidney disease. Study the impact of SGLT2i on bone and mineral metabolism in this patients' population.

Paget's disease of the bone (PDB) is a skeletal disorder with a strong genetic component which can be associated with various complications such as pain, bone deformity, arthritis and deafness. Recent advances in understanding the genetic determinants of PDB offer the prospect of developing a genetic profiling test which can be offered to people with a parent or sibling with PDB to determine how likely they are to develop the disease themselves. The aim of the study is to perform genetic testing for variants associated with PDB in people aged 45 and above who have a parent or sibling (first degree relative) with the disease. The Investigators will assess how well genetic profiling performs in predicting PDB by performing an imaging technique called a radionuclide bone scan which is a very sensitive way of detecting early PDB. This scan will be performed on entry to the study and again after five years. The reason for performing two scans five years apart because PDB becomes more common with age and so this will allow the Investigators to give an accurate indication of how good the genetic profiling test is in people at different ages. In addition to genetic profiling the investigators will analyse blood samples for biochemical markers of PDB and also test saliva and stool samples for the microbiome profile since its thought that this may influence risk of the disease as well. In the longer term the investigators hope the study will allow them to develop a blood test to stratify for risk of PDB and use bone scans only in people who the clinicians think are at highest risk of developing the disease. This will allow people with PDB to be picked up early allowing treatment to be given in a timely manner.

Hypothesis: Circulating monocytes RANK and MCSF-R expression is predictive of Cystic Fibrosis-related Bone Disease. Study design: Single-center comparative cross-sectional study Population: Patients with a CFTR channel mutation causing cystic fibrosis consulting the Centre de Ressources et de Compétences de la Mucoviscidose (CRCM) at Reims University Hospital will be recruited. Healthy controls will be recruited from donors at the Etablissement Français du Sang Grand Est, Reims. Judgment criteria: - Main judgment criterion: X Expression level of CD115 (MCSF receptor) and CD265 (RANK) evaluated by flow cytometry receptors on the membranes of circulating monocytes. - Secondary judgment criteria: X Rate of circulating CD115 +, CD265 +, CD115 + / CD265 + monocytes X Number of multinucleated cells with more than 2 nuclei and with an actin ring observed under fluorescence microscopy after osteoclastic differentiation X Surface of dentin resorbed in vitro by osteoclasts during an osteoclastic functionality test on dentin X Serum S1P levels assayed by ELISA technique. Investigation plan: Any eligible patient will be offered to participate in the study during the consultation at the CRCM. If the patient agrees to participate in the study, he/she will be included. Participation in the study will not affect its coverage. Participation will lead to the collection of three tubes of whole blood additional to those used as part of usual care, as well as the collection of demographic data (age, sex, height, weight, body mass index), sports practice, clinical images and interpretation, medical history (diabetes, infectious status, bone metabolism disorders, drug treatments followed, psychiatric disorders). Any subsequent donor from the EFS GE collected under the ALC / PIL / DIR / AJR / FO / 606 agreement and presenting characteristics of age +/- 2 years and identical gender will then be included. Statistical analysis plan: Qualitative variables will be described in terms of number and percentage. The quantitative distribution variables according to the Normal law will be described in the form of mean +/- standard deviation or in the form of boxplots (median, quartiles, deciles) if a distribution not following the Normal law is observed. ANOVA test, non-parametric Wilcoxon signed-rank test or chi² test will be aplied depending on the application conditions. A value of p <0.05 will be considered statistically significant.

The purpose of this European, multicentric, prospective, non-interventional study is to document and evaluate the efficacy and safety of the treatment of severely infected patients with intravenously administered fosfomycin, including patients with osteomyelitis, complicated urinary tract infection, nosocomial lower respiratory tract infection, bacterial meningitis/central nervous system infection, bacteraemia/sepsis, skin and soft tissue infection, endocarditis or other infections, each as far as covered by the respective nationally relevant SmPC.

Currently the diagnosis of OA is based on radiographs and clinical findings, which is limited to detecting late-stage disease. There is a pressing, unmet clinical need for robust assessment of early changes in cartilage health. Towards this goal, extensive efforts are ongoing to develop quantitative MRI for cartilage matrix analysis. MR T1ρ and T2 relaxation times have shown to be promising imaging biomarkers for early cartilage degeneration and prediction of disease progression. However, many challenges remain to clinically applying these techniques, including lack of standardized acquisition and quantification methods, and long acquisition times. The study aims to develop novel, fast and reproducible MR T1ρ and T2 relaxation time imaging methods on MR systems from multiple vendors and establish a platform for standardization and cross validation of these measures as a tool for clinical trials using such techniques. Following method validation, patients at risk for osteoarthritis will be tested.
