PTH And Calcium Responses to Exercise in Older Adults Experiment 2 (PACE Sr. 2)

Osteoporosis

Declines in serum calcium during exercise may cause increases in markers of bone resorption. This study will determine if preventing the decline serum ionized calcium experienced at the onset of exercise through the use of a "calcium clamp" also prevents increases in blood biomarkers associated with bone resorption.

OsteoporosisBone Loss

Bone fracture occurrence is associated with an increasing of morbidity and mortality. Some factors of fracture occurrence have been highlighted. For example, some diseases or therapy are known to increased risk of bone fracture only in some patients. Accordingly, it is important for clinicians to identify patients at risk for bone fracture. Right now, various tools are available for the clinicians: clinical exam, bone mineral density assessed by Dual Energy X-ray Absorptiometry (DEXA), an algorithm based on interrogation, clinical exam and bone mineral density. However, prediction of bone fracture risk needs to be improved since only 50% of bone fractures can be predicted. DEXA provides information for fracture risk estimation, but it is unable to distinguish cortical part to trabecular part. It also fails to quantify the microstructural properties that influence bone strength. Bone microarchitecture, including the cortical compartment can now be assessed in vivo by the HR-pQCT. This technique allows access to several parameters: on the one hand the volumetric bone mineral density for the whole area measured as well as cortical and trabecular regions, and on the other hand, the thickness and cortical porosity and the number of trabecular, their orientation and distribution. Thus, the HR-pQCT allows realizing a virtual bone biopsy and provides information on cortical and trabecular bone microarchitecture. This is the only noninvasive way to assess cortical and trabecular bone microarchitecture.

Markers of Osteoporosis in Cystic Fibrosis

Cystic Fibrosis

Main Study Up to 100 subjects, both non-CF volunteers and Cystic Fibrosis (CF) patients, will participate in a single study visit that will include a DEXA scan, micro CT, and blood collection. Denosumab (Prolia) Sub study Approximately 10 adult subjects with CF who participated in the main study and have results indicating bone disease will receive treatment with Denosumab for up to 5 years. They will be asked to return annually for repeat DEXA scans, micro CT, and blood collection.

Osteoporosis

This study is a non-interventional observational study. On the baseline (Visit 1), we collect demographic data from all participating subjects according to their daily medical conditions, prescribe drugs and collect validity and safety data according to the research plan in Visit 1 and Visit 2. In addition, we collect data by application on subject's self-awareness symptoms and subject's questionnaire for medical outcome short form health survey (SF-36) every day from the baseline for 4 days.

the Type ONe dIabetic Bone Collaboration Study

Osteoporosis SecondaryDiabetes Mellitus1 more

In this cross-sectional clinical study, we will examine the bones of 111 Type 1 Diabetes (T1D) patients and 37 age-matched healthy controls with the aim of describing a T1D Bone Phenotype. The main Objectives of the study is a) to determine if the material properties of the bones are affected in diabetic bone disease and b) to determine if the mitochondrial function in osteoclasts and osteoblasts is impaired in T1D. Secondary end points are c) to establishment of the T1D bone phenotype and d) to investigate if mitochondrial dysfunction in T1D bone cells correlates to changes in gene expression, gene activity, bone remodelling, bone density, microarchitecture, geometry and material properties. Furthermore, in terms of contributing to knowledge on etiology and pathology of type one diabetic bone disease, we will study the predictory value of muscle mass in T1D patients and controls, as well as other characteristics such as heart rate variability (HRV) and AGE content. Furthermore, we will study the epidemiology of osteoporosis and fractures in Danish T1D patients. To assess the material properties of the bones, we will measure the bone mass density (BMD), use High Resolution peripheral Quantitative Computed Tomography (HRpQCT) for assessment of the microarchitecture and finite element analysis of bone strength, and by microindentation, we will obtain direct measures of the strength of the cortical bone of the tibia. Further we will measure bone turnover markers and circulating microRNA and in a subgroup of participants (24 T1D, 12 controls) bone samples will be retrieved for examination of bone histomorphometry (structural and static parameters) and cell samples from blood and bone marrow will be used for in vitro experiments focused on cell differentiation mitochondrial function, as hyperglycemia may affect mitochondrial function. Finally measures of some possible predictors of bone fragility in subjects with T1D are examined (sarcopenia, skin advanced glycation end products (AGE) content, autonomic neuropathy)

Prevalence of Hidden Hypercortisolism in Osteoporosis

OsteoporosisCortisol Excess

The goals of this observational study are the following: i) to assess the prevalence of hidden hypercortisolism (HidHyCo) in a sample of osteoporotic patients; ii) to compare the clinical characteristics between osteoporotic/osteopenic patients with HidHyCo and those without HidHyCo in order to determine the clinical characteristics more frequently associated with the HidHyCo presence in the osteoporotic population and to identify those osteoporotic patients worthy of HidHyCo screening. In all patients who have been included in the study and who have given the informed consent to participate in the study we will perform 1 mg overnight dexamethasone suppression test (F-1mgDST). In all subjects with F-1mgDST >1.8 mcg/dL, cortisol levels after two-day low dose (2 mg/day) dexamethasone suppression test (F-2mgx2dDST) will be measured. Patients with F-2mgx2dDST above >1.8 mcg/dL will be considered affected with HidHyCo and will be managed following the available guidelines for hypercortisolism. The HidHyCo could be present in a not negligible percentage of osteopenic/osteoporotic patients. In these patients, osteoporosis and, if present, other comorbidities (i.e. hypertension and/or diabetes) can improve by the surgical resection of the adrenal or pituitary adenoma if feasible, or by the use of drugs able to modulate cortisol secretion or glucocorticoid sensitivity.

Incidence of the Treatment faIlure in Osteoporosis

OsteoporosisTreatment Failure

Osteoporotic fractures are associated with significant morbidity, increased mortality and reduction in the quality of life, available treatments reduces the fracture risk between 30 and 70%, however some patients experience a new fracture and/or continue to loose bone during treatment; this has been defined as treatment failure (TF). The epidemiology and biological bases of TF are currently under-investigated, thus it is impossible for the physician to forecast patients' answer to treatment. The aims of TAILOR study are to collect sounded epidemiological data on TF in a real life setting. To this extent, the investigators will retrospectively a large cohort of 5000 patients with at least 60 months of anti-osteoporotic treatment followed in our center for the diagnosis and care of bone metabolic diseases, and compare TF patients to adequate responders (ARs) for clinical characteristic and biological parameters. The results will be a "signature" to identify those patients who will experience TF.
