Jaccoud-type lupus arthropathy

Abstract

Background: Jaccoud's arthropathy (JA) is a condition characterized by joint deformities that have a "reducible" pattern, that is, they return to the normal appearance with a passive manoeuvre. JA was described in patients with rheumatic fever (RF) more than a century ago, and presently, the majority of the patients have systemic lupus erythematosus (SLE).

Purpose: The aim of this review is to draw one attention to the epidemiology, pathogenesis, histopathology, clinical features, imaging, and management of JA in patients with SLE (Jaccoud-type lupus arthropathy).

Data collection: The search strategy included articles retrieved from PubMed utilizing the terms "lupus arthropathy", "lupus deforming arthropathy", "lupus hand", "lupus foot", "chronic postrheumatic arthropathy", "Jaccoud's" and "Jaccoud" from 1950 until March 2021, with no language restriction.

Results: The prevalence of Jaccoud-type arthropathy in SLE is approximately 5%. The aetiopathogenic mechanisms of JA are not yet known. The most common joint deformities of JA, are ulnar deviation, swan neck, and the "z" of the thumb. Unfortunately, none of the proposed classification criteria for JA have been validated so far. Characteristically, there is no bone erosion on plain radiographs of the joints, but more sensitive imaging methods, magnetic resonance imaging or high-performance ultrasound may reveal small bone erosions. There is no preventive measure against JA development, specific clinical treatment or convincing surgical approach for correcting the deformities.

Conclusion: As daily activities and quality of life are compromised in patients with JA, other studies are urgently needed in this area.
