BBD Longitudinal Study of Osteogenesis Imperfecta
Study Details
Study Description
Brief Summary
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.

Detailed Description
The purpose of this natural history study is to perform a long-term follow-up of a large group of people with osteogenesis imperfecta (OI). The research aims are:
-
To collect natural history data on all individuals enrolled in this longitudinal study. The cause of the brittle bone disease will be compared with things like severity, various features and response to treatments.
-
To determine how often people with type I OI have vertebral compression fractures of the spine.
-
To determine how often people with OI develop scoliosis (curvature of the spine).
-
To determine how often people with OI have problems with teeth alignment and how dental health impacts a person's quality of life.
-
To determine the effect of pregnancy in women with OI.
There will be a total of 1000 people with OI in this study. Participants will be asked to come in every year if 17Y and younger or every other year if 18Y and older for a total of five years.
The following information will be collected at the study visits:
Birth History and past surgical history, Current medical history, Scoliosis evaluation, Walking ability Questionnaire, Dental Quality of Life Questionnaire, Scoliosis and fractures Quality of Life Questionnaires, Physical development evaluation, Medications Use
The following tests will be performed:
Physical exam, dental exam, lung function test, hearing test, mobility test.
The following X-rays will be taken:
DEXA scan, X-ray of the spine, X-ray of the jaw.
Biospecimen (urine and blood) samples will be collected.

Outcome Measures
Primary Outcome Measures
- Natural History of OI [5 years]

- Incidence of Oral and craniofacial anomalies [5 years]
Incidence and progression of oral and craniofacial anomalies as captured by panorex and dental exam
- Satisfaction of Oral Health 15Y+ [5 years]
Satisfaction of Oral health as measure by the OHIP 20
- Satisfaction of Oral Health 11Y-14Y [5 years]
Satisfaction of Oral health as measure by the Oral health QOL 11-14Yrs
- Effect of pregnancy in women with OI [2 years]
Change in Spine, Hip, and radius Bone Mineral Density in pregnant women with OI
Eligibility Criteria
Criteria
Natural History Study:
Inclusion Criteria:
-
Individuals with OI diagnosed by molecular (DNA) analysis OR
-
Individuals whose clinical history and radiographs are highly suggestive of OI, but whose diagnosis has not been verified by biochemical or molecular studies
Exclusion criteria:
-
Individuals who are unable to return for their scheduled follow up visits.
-
Individuals with skeletal dysplasias other than OI
-
Individuals with OI and a second genetic or syndromic diagnosis
Vertebral Compression Fractures component Inclusion criteria
• Patients with nonsense or frameshift mutations in COL1A1 or COL1A2 of any age and clinical features of OI type I.
Exclusion criteria
-
Use of a bone-acting treatment agent such as bisphosphonates, calcitonin, calcitriol, fluoride, etc., within one year of enrollment.
-
Conditions other than Osteogenesis Imperfecta-HaploInsufficiency (OI-HI) affecting muscle and/or bone development (i.e. cerebral palsy, rickets)
-
Nonsense or frame shift mutations in the final coding exons of COL1A1 or COL1A2, as this may not lead to haploinsufficiency.
Scoliosis in OI component:
Inclusion Criteria
-
All study participants between the ages of 3 to 17 years OR
-
Study participants 18 years and older with scoliosis
Dental and Craniofacial Abnormalities in OI component:
Inclusion Criteria • All subjects aged 3 years and older enrolled in the Longitudinal Study Exclusion Criteria Subjects who refuse the dental examination
Pregnancy in OI component:
Inclusion criteria
• Females of reproductive age with mutations in any known gene causing OI, who are contemplating pregnancy within 5 years of enrollment in the Natural History Study OR Females who are pregnant with available pre-pregnancy BMD (within 5 years prior to the first pregnancy visit).
Exclusion criteria
-
Males
-
Females who are peri-menopausal or menopausal
-
Females who had gestations associated with higher order multiples.
