Bisphosphonate Therapy for Osteogenesis Imperfecta
Summary
The study is designed to evaluate the efficacy and safety of "Bisphosphonate Therapy for Osteogenesis Imperfecta (OI)." We, the researchers at Indiana University School of Medicine, are characterizing the changes effected by oral bisphosphonate therapy and comparing them to a regimen of intravenous bisphosphonate therapy in a group of children with OI and also in children with other disorders that result in low bone mass and fractures.
Description
The study is designed to evaluate the efficacy and safety of "Bisphosphonate Therapy for Osteogenesis Imperfecta (OI)." OI is an inherited disorder of collagen synthesis. Collagen is the major structural protein of the matrix of tendons, skin, and bones. Affected persons have low bone mineral density (and experience multiple fractures and progressive bony deformity). In its most severe form, the disorder is lethal in infancy. We plan to characterize the changes effected by oral bisphosphonate therapy and compare them to a regimen of intravenous bisphosphonate therapy in a group of children with OI.
Additionally, we have begun to treat patients with OI and other conditions of low bone mineralization for age who are not eligible for the standard protocol (too young, history of abdominal pain, etc.) with bisphosphonate. We also plan to screen the parents and siblings of our patients diagnosed with osteogenesis imperfecta, in order to determine if they also have osteoporosis.

Medical and Biotech [MESH] Definitions
Osteogenesis Imperfecta
Autosomal dominant COLLAGEN DISEASES resulting from defective biosynthesis of COLLAGEN TYPE I and characterized by brittle, osteoporotic, and easily fractured bones. It may also present with blue sclerae, loose joints, and imperfect dentin formation. There are four major types, I-IV.
Alendronate
A nonhormonal medication for the treatment of postmenopausal osteoporosis in women. This drug builds healthy bone, restoring some of the bone loss as a result of osteoporosis.
Chondrogenesis
The formation of cartilage. This process is directed by CHONDROCYTES which continually divide and lay down matrix during development. It is sometimes a precursor to OSTEOGENESIS.
Amelogenesis Imperfecta
A clinically and genetically heterogeneous group of hereditary conditions characterized by malformed DENTAL ENAMEL, usually involving DENTAL ENAMEL HYPOPLASIA and/or TOOTH HYPOMINERALIZATION.
Osteogenesis
The process of bone formation. Histogenesis of bone including ossification.

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 t...
Pamidronate to Treat Osteogenesis Imperfecta in Children
This study will evaluate the effect of pamidronate-a drug that decreases bone resorption (breakdown)-on osteogenesis imperfecta. This is a genetic disorder of collagen, the major protein...
Safety and Efficacy of Risedronate in the Treatment of Osteogenesis Imperfecta in Children
Children with Osteogenesis Imperfecta (OI) have bone pain, low bone mass and fractures. There are no approved drugs for the treatment of OI in children, even though some intravenous (IV) b...
Zoledronic Acid in Children (1 -17 Years) With Severe Osteogenesis Imperfecta
This is an extension study to examine the long-term safety and efficacy of zoledronic acid in patients who have completed the core CZOL446H2202 study.
Marrow Mesenchymal Cell Therapy for Osteogenesis Imperfecta: A Pilot Study
Osteogenesis imperfecta (OI) is a genetic disease for which there is currently no known cure. OI causes the osteoblasts (bone-forming cells in the body) to grow poorly, which slows the gro...

Distal patellar tendon avulsion fracture in a football player with osteogenesis imperfecta.
Proximal patellar tendon ruptures have been described in adults with osteogenesis imperfecta, but distal avulsions from the tibial tubercle have not. This is the first case reporting a distal patellar...
New perspectives on osteogenesis imperfecta.
A new paradigm has emerged for osteogenesis imperfecta as a collagen-related disorder. The more prevalent autosomal dominant forms of osteogenesis imperfecta are caused by primary defects in type I co...
