Jaccoud's arthropathy in systemic lupus erythematosus (SLE) affects about 5% of patients, causing reducible joint deformities. Current treatments are limited, highlighting the need for further research to improve patient quality of life.
Area of Science:
- Rheumatology
- Immunology
- Orthopedics
Background:
- Jaccoud's arthropathy (JA) is characterized by reducible joint deformities, historically linked to rheumatic fever but now predominantly seen in systemic lupus erythematosus (SLE).
- This condition significantly impacts patients' daily activities and quality of life.
Purpose of the Study:
- To review the epidemiology, pathogenesis, histopathology, clinical features, imaging, and management of Jaccoud-type lupus arthropathy (JLA).
Main Methods:
- A literature search was conducted on PubMed using terms like "lupus arthropathy" and "Jaccoud's" from 1950 to March 2021.
- No language restrictions were applied to the search.
Main Results:
- Jaccoud-type arthropathy occurs in approximately 5% of SLE patients.
- Common deformities include ulnar deviation, swan neck, and thumb "Z" deformity, with no validated classification criteria.
- While plain radiographs show no bone erosion, advanced imaging like MRI and ultrasound may detect small erosions. Etiopathogenic mechanisms remain unknown.
- Currently, there are no preventive measures, specific clinical treatments, or effective surgical options for JA deformities.
Conclusions:
- Further research is urgently needed to address the management and treatment of Jaccoud's arthropathy in SLE patients.
- Improving quality of life for affected individuals is a key unmet need.
