Active clinical trials for "Bone Diseases, Metabolic"

Performing adduction and abduction resistance exercise will increase hip bone density and strength to a greater extent than doing squat and deadlift exercise. Aim #1: To determine if doing hip adduction and abduction resistance exercise training for 16 weeks improves spine bone mineral density and hip bone mineral density and strength as determined by finite element modeling. Aim #2: To compare the effects of hip adduction and abduction exercise to squat and deadlift exercise with respect to potential changes in hip bone mineral density and strength. Aim #3: To determine if the addition of adduction and abduction exercise to squat and deadlift exercise promotes an "additive" effect with respect to changes in spine bone mineral density and hip bone mineral density and bone strength.

An adequate calcium intake is important for bone turnover and the risk of developing osteoporosis. Yet many studies have documented that supplementation with calcium tablets are often associated with a poor compliance, therefore it is important to explore ways to better calcium influx. Calcium consumed through dairy products must first be cleaved from the molecules which it is bound to before it can be absorbed. Chymosin is an enzyme which cleaves the protein binding between some amino acids in κ-casein. The reaction occurs after ingestion of milk and causes a process whereby the time the milk is staying gastrointestinal tract is extended, this can lead to enhanced uptake of calcium. When the body's calcium balance is in equilibrium excretion in urine (24 h) in roughly the size of the intake, whereby a measurement of circadian urine excretion of calcium can determine the amount of calcium absorbed from the intestine. The investigators want to clarify whether the addition of chymosin to milk increases calcium absorption. Secondary to explore issues of significance for this effect, including vitamin D status and amount of daily calcium intake and whether a change in calcium absorption has immediate effects on bone turnover (measured as plasma osteocalcin, bone specific alkaline phosphatase (BSAP), and the renal excretion of cross-linked N-terminal telopeptide of type 1 collagen (NTx/Cr) ratio) and on the parathyroid function (measured as PTH). Finally we will explore relations between bone mineral density (BMD) and the measured parameters (in terms of P-PTH, P-25OHD, P-1,25(OH)2D, P-osteocalcin, P-BSAP, and U-NTx/Cr).

A 48-week, open label, non comparative prospective trial in stable chronic human immunodeficiency virus-infected patients having achieved complete virological suppression for more than 24 weeks (human immunodeficiency virus-1 RNA <50 c/ml) switching from an antiretroviral regimen containing tenofovir and lamivudine or emtricitabine and boosted protease inhibitor to boosted atazanavir and lamivudine Study visits will take place at screening, baseline, weeks 4, 12, 24, and 48.

Idiopathic inflammatory myopathies (IIM) patients are at high risk of development of reduced bone mineral density due to impairment of functional status due to the disease and a relatively high dose of glucocorticoid use for the treatment. Reduced bone mineral density is prevalent in local IIMs patients. Denosumab and zoledronic acid are established treatments for osteoporosis in postmenopausal women and glucocorticoid-induced osteoporosis. However, the role of these treatments in reduced bone mineral density including osteoporosis and osteopenia related to IIMs are lacking. There is also no evidence on comparing the efficacy of the two agents. Therefore, the investigators conducted this prospective randomized controlled study to compare the efficacies of denosumab and zoledronic acid in treating reduced bone mineral density in IIMs patients. The hypothesis in this study is that treatment by denosumab or zoledronic acid would improve bone mineral density in IIMs patients with reduced bone mineral density.

The study hypothesis is to determine the feasibility of switching HIV-HCV co-infected patients receiving methadone or buprenorphine/naloxone as opioid substitution therapy with suppressed HIV RNA viral load on current antiretroviral therapy to elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF, Genvoya™) followed by 12 weeks of HCV antiviral therapy with sofosbuvir/velpatasvir (SOF/VEL, Epclusa™), followed then by switch to bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF, Biktarvy™) for an additional 48 weeks.

This study will determine the prevalence of endocrine-related side effects in children who have been treated for cancer and establish a database and registry organized according to cancer diagnosis, treatments and endocrine side effects. In children, the endocrine system, which includes glands and hormones that help to control metabolism, growth, development and reproduction, is particularly vulnerable to long-term side effects associated with cancer and its treatments. The study will also serve to help train medical fellows, residents and students in identifying and managing endocrine abnormalities in children who have been diagnosed with and treated for cancer. Children between 2 and 24 years of age who have been treated for a childhood cancer and have been disease-free for at least 1 year may be eligible for this study. All participants undergo the following procedures: Review of cancer treatment record Review of medical and family history Blood draw for DNA studies Physical examination and body measurements (height, weight, waist, body proportions) Completion of child health questionnaires Individualized screening and counseling program Review of the following endocrine systems: growth, pituitary and hypothalamic function, thyroid function, ovary and testicular function, bone health, risk of obesity and diabetes The following additional studies may be done, as clinically indicated: Magnetic resonance imaging (MRI) of the brain Thyroid, testicular or ovarian ultrasound DEXA scan to measure bone density Wrist x-ray to measure bone age Blood tests Urine pregnancy test for girls who are old enough to have menstrual periods Stimulation testing (tests that involve giving medicine by mouth or in the vein and then measuring blood levels of substances afterwards, such as oral glucose tolerance test, arginine-clonidine growth hormone stimulation test, ACTH stimulation test, and gonadotropin-releasing hormone stimulation test) Children with endocrine abnormalities are offered standard treatments.

The hypothesis for this study is that the GLP-1Ra Semaglutide has a positive effect on the balance between build-up and degradation as well as the strength of the bones in men and women aged 40-85 years at increased risk of bone fractures. Treatment involves injection of Semaglutide 1.34 mg/ml once a week or corresponding volume of placebo once a week for 52 weeks. The effect will be measured by bone markers in blood samples, bone scans, bone tissue tests (bone biopsy), and direct bone strength measured by microindentation at the start and end of the study.

This multi-center, randomized and exploratory clinical trial is designed to evaluate the effect of bone metabolism and blood sugar of evogliptin and dapagliflozin in the menopause female patients with osteopenia and type 2 diabetes. The trial will evaluate bone metabolism (bone markers and bone density) and blood sugar (AGE and glucose variability) after 12 weeks and 48 weeks. This clinical trial conducts in two arms, and each arm recruits 60 subjects.

This study investigates the efficacy and mechanism of traditional Chinese medicine formula power product in the treatment of osteopenia in patients with pain. Half of participants will receive Chinese medicine formula power product, while the other half will receive a placebo.

There is a deficit in the number of 'age-appropriate' formulations available for the delivery of medicines to children. Liquid preparations are considered the 'gold standard' for delivering medicines to children however many of these are formulated using ingredients which can be toxic to children (e.g. preservatives, alcohols), particularly to neonatal babies (< 4 weeks old) who do not possess the metabolic processes and mature organ function of older children or adults. Rapidly dissolving oral thin films (OTFs) dissolve quickly in the saliva, releasing the active ingredient(s) without the need for chewing or water, making them ideally suited to patients who find it difficult to swallow other oral dosage forms such as tablets or capsules. The aim of this study is to demonstrate that OTFs can offer a safe and effective alternative for oral administration of phosphate supplements to neonatal infants for the treatment of hypophosphataemia and osteopenia of prematurity. It is hypothesised that this treatment will be equal to standard therapy using an oral solution. Babies born before 32 weeks gestational age are routinely supplemented with oral phosphate as soon as they have been established on oral feeds in order to prevent bone disorders such as osteopenia. Babies recruited to this study will be given phosphate supplementation as per NHS Greater Glasgow and Clyde guidelines. This single-centre cross-over study will take place in the intensive care and special care baby units at the Princess Royal Maternity in Glasgow. The investigators aim to recruit 20-30 babies and will use blood phosphate levels (obtained from routine sampling only) to evaluate treatment effect. Babies will be randomised to receive either OTFs or oral solution of potassium acid phosphate for 2 weeks followed by 2 weeks of the other therapy. The investigators hypothesise that OTF treatment will be equivalent to standard oral solution.
