Active clinical trials for "Osteogenesis Imperfecta"

Osteogenesis Imperfecta (OI) is a rare disorder of increased bone fragility characterized by fractures with minimal or absent trauma, dentinogenesis imperfecta (DI), and, in adult years, hearing loss. It is seen in both genders and all races. The clinical features of OI represent a continuum varying from perinatal lethality to individuals with severe skeletal deformities, mobility impairments, and very short stature to nearly asymptomatic individuals with a mild predisposition to fractures, normal stature, and normal lifespan. Fractures can occur in any bone, but are most common in the extremities. These disorders can be devastating and progressive and result in deformity, chronic pain, impaired function and loss of quality of life. The overall goal of this study is to answer specific question about the natural history of brittle bone diseases as defined by molecular etiology and to develop the foundation for prospective clinical studies.

Osteogenesis imperfecta (OI) is a rare genetic disease due to a mutation in one of the genes encoding either type I collagen or a protein involved in its synthesis. This leads to bone fragility with fractures and deformities. However, other tissues rich in type I collagen can also be affected, such as teeth or vessel walls. In the literature, several case reports describe tendon ruptures in OI patients, but no original study has really addressed this issue, which is likely to impact the quality of life through a reduction in mobility and pain. Recent work carried out by the investigators shows an alteration of the osteotendinous unit in the osteogenesis imperfecta mouse (oim), a validated model of the most severe form of OI. Consequently, the project aims to study the damage of tendon and ligament in patients suffering from osteogenesis imperfecta.

The primary objective of this study is to evaluate the effect of romosozumab treatment for 12-months compared with bisphosphonate(s) on the number of clinical fractures at 12-months; the number of any fractures at 12-months and change in lumbar spine bone mineral density (BMD) Z-score at 6-months.

O.I with NOF fixed by Wagner technique and telescoping nail

This research study aims to evaluate the effect of a 6-month adapted physical activity program (APA) on the endurance capacities (evaluated as the maximum oxygen consumption [VO2 peak]) of children and adolescents with Osteogenesis Imperfecta.

The aim of this study is to assess the effective of intraoperative use of tranexamic acid in reducing blood loss during telescoping nail application in cases of osteogenesis imperfecta.

Osteogenesis imperfecta (OI) is a group of congenital and heritable bone disorders that currently affects at least 50,000 people in the United States. OI varies in severity from perinatally lethal to mild forms. The majority of cases is caused by a dominant mutation in type I collagen genes (COL1α1 and COL1α2), altering the quantity or quality of type I collagen. Although OI is typically characterized as a disease of the bone, it is perhaps more accurately described as a connective tissue disorder. Type I collagen is a major constituent of lung connective tissue. Respiratory insufficiency is the leading cause of death in patients with OI. Thus, it is important and necessary to understand the etiology of the restrictive pulmonary physiology in the OI population.

The aim is to determine whether vestibular deficits are present in OI, then to establish whether a correlation exists between genetic type, severity of OI and audiovestibular phenotype. OI patients aged 12 to 20 years will undergo an audiometric, immittance, and vestibular assessment. When hearing loss is conductive or mixed or in cases where vestibular deficits are identified, a CT scan without injection will be performed. In case of sensorineural hearing loss or abnormal CT results, an MRI will be performed.

Assess the postoperative functional outcomes after surgical correction of skeletal deformities of lower limbs in osteogenesis imperfecta patients as regard ambulation status, postoperative complications and reoperation rate.

ROI is a retrospective and prospective registry, finalized to care and research. It is articulated in main sections - strongly related and mutually dependent on each other - corresponding to different data domains: personal information, clinical data, genetic data, genealogical data, surgeries, etc. This approach has been individuated in order to corroborate and integrate data from different resources and aspects of the diseases and to correlate genetic background and phenotypic outcomes, in order to better investigate diseases pathophysiology.
