Joint calcification following intra-articular corticosteroid therapy

Area of Science:

• Rheumatology
• Pediatric Orthopedics
• Radiology

Background:

• Juvenile rheumatoid arthritis (JRA) can affect multiple joints.
• Joint calcification is an observed complication in some JRA cases.
• The etiology of joint calcification in JRA requires further investigation.

Purpose of the Study:

• To investigate the potential link between intrasynovial corticosteroid treatment and joint calcification in JRA patients.
• To determine the frequency and characteristics of joint calcification following corticosteroid injections.

Main Methods:

• A blind retrospective survey of 100 JRA patients' clinical records and radiographs.
• Analysis of treatment histories, specifically focusing on intrasynovial corticosteroid use.
• Radiographic assessment for the presence and location of joint calcification.

Main Results:

• 39 out of 100 patients received intrasynovial corticosteroid injections (affecting 92 joints).
• 20 cases of joint calcification were identified in 32 joints.
• All identified cases of joint calcification had a history of intrasynovial corticosteroid injections.

Conclusions:

• Intrasynovial corticosteroid injections appear to be associated with joint calcification in juvenile rheumatoid arthritis.
• Further research is warranted to understand the pathogenesis and clinical implications of this association.
