Indications and Interest of US-guided Synovial Biopsies Performed in Clinical Practice

Completed

• Conditions: Arthritis

• Registration Number: NCT03417167
• Lead Sponsor: Nantes University Hospital

Brief Summary

Synovial biopsies are now routinely performed both in research and in clinical practice. The developments of ultrasound (US) and of US-guided needle biopsies devices have facilitated their use and tolerance by the patients. However, their interest in clinical practice in the context of an undifferentiated arthritis remains debated.

Detailed Description

In this study, the investigators will collect all the synovial biopsies performed in clinical practice in 18 Rheumatology Unit throughout France. All the participants received a standardized training on US-guided synovial biopsies. For each biopsy, the indications, clinical presentation, procedure (length, tolerance), biopsy results (Pathology, bacteriology, etc ...) will be collected in a Clinical Research Form. The investigator will determine the number of cases where the synovial biopsy allows drawing a definite diagnosis.
