Spine Quantitative Computed Tomography (QCT)
Completed
- Conditions
- Juvenile Idiopathic Arthritis
- Registration Number
- NCT00762879
- Lead Sponsor
- Children's Hospital of Philadelphia
- Brief Summary
The purpose of this study is to compare healthy children to children who have a chronic illness called Juvenile Idiopathic Arthritis (JIA). JIA is a childhood disease that causes swollen joints that are often stiff and painful. JIA affects about 1 in 1,000 children age 16 and younger.
- Detailed Description
Children with chronic illnesses are at risk for bone fragility due to inflammation, glucocorticoid therapy, physical activity limitation, malnutrition, and pubertal delay. The impact of low bone mass during childhood may be immediate, resulting in childhood fractures, or delayed, due to suboptimal peak bone mass attainment.
