Active clinical trials for "Osteogenesis Imperfecta"

Osteogenesis Imperfecta (OI) is a genetic disorder caused by mutations to the alpha-1 or alpha-2 chain of type I collagen. Clinically, the disorder is characterized by bones that fracture easily, often from little or no apparent trauma. There is no information about Some institutions perform blood pressure monitoring on these patients with a cuff, while other institutions avoid this method due to concern for fracture. Instead, they use alternative forms of monitoring such as an arterial line. These methods come with their own risks, including clotting, decreased perfusion, and pain. In addition, arterial lines require intensive (and more expensive) monitoring in a pediatric intensive care unit due to risk of dislodgement and rapid blood loss. These blood pressure monitoring recommendations for patients with OI do not appear to be based on strong evidence. Anecdotally, some patients and healthcare professionals report hearing about individuals with OI who have suffered fractures from blood pressure cuffs. However, this is not well documented in the medical literature. Regular and accurate blood pressure monitoring is particularly important in the postoperative period, due to blood loss and fluid shifts, as well as utilization of advanced pain management techniques that can potentially impact blood pressure.

The purpose of this study is to investigate the effect of BPS804 on strength/quality of bone in patients with Type I, III or IV Osteogenesis imperfecta using a special type of CT scanner. Participants will be treated for 1 year.

Osteoporosis pseudoglioma (OPPG) syndrome is a rare autosomal recessive condition of childhood osteoporosis and congenital blindness for which new treatments are needed. We have found that body fat is increased in OPPG and muscle mass is reduced. We hypothesize that growth hormone therapy will improve muscle mass and bone strength in OPPG.

The proposed investigation is a pilot study that involves pediatric patients affected by spinal deformity (Adolescent Idiopathic Scoliosis and Osteogenesis Imperfecta). The main goal is to evaluate the acceptability, the safety and the overall satisfaction of the patients wearing the back braces produced with an innovative methodology using 3D printers, compared to the current braces manufactured with a production model based on thermoforming, that has well-established clinical efficacy.

Overall Objective: To test the hypothesis that oral vitamin D supplementation at higher than currently prescribed doses has a beneficial effect on the skeleton of young patients with osteogenesis imperfecta (OI). Specific Aims: 1. To determine whether 12 months of high-dose vitamin D supplementation, compared to standard-dose vitamin D supplementation, increases areal bone mineral density z-scores at the lumbar spine. 2. To examine the effectiveness of high-dose vitamin D supplementation to increase trabecular and cortical bone mineral density at the radius. 3. To examine whether high-dose vitamin D supplementation has an effect on physiological determinants of bone mass (parathyroid hormone, activity of bone metabolism, muscle function). Background: In a preliminary cross-sectional study of 282 OI patients we observed an inverse relationship between serum 25-hydroxyvitamin D and parathyroid hormone levels and a positive relationship between circulating levels of 25-hydroxyvitamin D and lumbar spine areal bone mineral density z-scores. This suggested that high-dose vitamin D supplementation would have a beneficial effect on bone density. Most OI patients currently receive oral vitamin D supplementation of 400 International Units per day, but doses of 2000 International Units per day are safe and have been shown to be beneficial in studies on healthy adolescents. Study Design: This is a parallel-group double-blind randomized controlled trial of 12 months duration on 60 children and adolescents aged 6 to 19 years with a clinical diagnosis of OI. One group of 30 participants will be randomized to receive vitamin D3 at a dose of 2000 international units per day ('high-dose group'). The other group of 30 participants will be randomized to receive vitamin D3 at a dose of 400 international units per day ('standard-dose group'). Randomization will be stratified according to pubertal status and bisphosphonate treatment status. Clinical Relevance: The proposed study aims at direct improvements in the care of OI patients. If a simple and low-cost 'intervention' such as high-dose vitamin D supplementation can be shown to be effective in relieving some of the disease burden associated with OI, the benefit to OI patients worldwide would be substantial.

The investigators have currently finished conducting an international multi-center trial that compares the efficacy and safety of pamidronate and zoledronate in the treatment of moderate to severe forms of Osteogenesis Imperfecta (OI). This trial has included only children above one year of age. The aim of the current study is to extend the observations of that currently finished study to infants below 1 year of age. Moreover, it is possible to administer zoledronate in a single short infusion instead of the three-day cycles with Pamidronate, therefore decreasing patient and family burdens with shorter stays in the hospital.

Osteogenesis imperfecta (or brittle bone disease) is a rare genetic disease characterized by fragile bone and a low mass ossue, secondary to abnormal collagen synthesis. This is a real congenital osteoporosis. The prevalence of the disease is not known precisely, but it is 1 in 10000 at 20000. There are many forms of osteogenesis imperfecta to classify patients with symptomatology minor to the patients with lethal form during the neonatal period. The main symptoms are dominated by fractures and bone deformities, particularly in the lower limbs. Bisphosphonate medication is used for over 10 years to reduce the number of fractures. However the long-term effects are not known to date, not allowing even to establish proof of the benefit risk. Thus unable to process all of these patients and over a long time, these drug treatment leaves much therapeutic solutions to surgery. The goal of surgery is to treat fractures, treat bone deformities and prevent fractures future. In the long bones of the limbs, the only effective techniques are intramedullary nailing. The majority of realized nailing nailing are either sliding or telescopic enabling having a reinforced bone of an intramedullary osteosynthesis material over its entire length during the period of bone growth. It has been shown that the technique of the sliding nailing was inexpensive but reliable especially before the age of 5 years. After that age, all are telescopic nailing nailing. The first telescopic nail described is the Bailey-Dubow nail still widely used in France. However, the number of complications relating to its use is important. Thus, there are 8% of disunity equipment and 33 to 72% of the nail migration forcing him to change one or more times during growth. A new nail presented at the French orthopedic company in 2005 and Fassier Duval reported a much lower complication rate because the rate of nail migration is only 9%, without opening the knee joint, which is not possible with the highlight of Bailey-Dubow. It is proposed to conduct a prospective series of 10 nailing the lower extremities with this nail Fassier-Duval in patients with osteogenesis imperfecta and compare the results with a series of patients already treated with Bailey-Dubow nails in order to highlight the advantages and disadvantages of using of such a nail.

An exploratory, open label, multiple dose, phase I/II trial (n=15) evaluating safety and efficacy of intravenous and intraosseous infusion of allogeneic expanded fetal mesenchymal stem cells (MSC) for the treatment of severe Osteogenesis Imperfecta (OI) compared with historical and untreated prospective controls.

Hypothesis: one-dose pamidronate will prevent post-operative bone loss in children at risk for low bone density Plan: children with chronic disease such as CP, spina bifida, etc. will be recruited pre operatively and studied with DXA scan. After surgery, children will be randomized to receive either pamidronate or saline. Repeat DXA scan will determine bone lost after end of immobilization or nonweightbearing.

Osteogenesis imperfecta (OI) is a rare genetic disorder of increased bone fragility and low bone mass. It is conceivable that children and adolescents with OI are less active than healthy peers because of frequent fractures, immobilization,functionals limitations and no adapted physicals activity(APA). The hypothesis is that an Adapted physique activity could improve access of activity for patients with Osteogenesis Imperfecta (OI). The aim of the study is to evaluate benefice of APA,improve aerobic capacity, cardiovascular and bone benefits, and gain of quality of life. Children with OI between 6 and 18 years old will have a program of supervised "adapted training program" during one year. The program is adapted at each individual and without risk for the patient.
