Hands Deformity in a Patient with IgA Vasculitis.

Area of Science:

• Rheumatology
• Immunology
• Internal Medicine

Background:

• IgA vasculitis is a systemic autoimmune disease.
• Arthritic complaints and hand deformities can be presenting symptoms.
• Rheumatic evaluation is crucial for diagnosis and management.

Observation:

• A 74-year-old female with IgA vasculitis presented with arthritic complaints and hand deformities.
• Physical examination revealed reversible Jaccoud's arthropathy with swan-neck deformities.
• Radiographs showed an absence of erosions in the affected joints.

Findings:

• Jaccoud's arthropathy is a non-erosive arthropathy.
• It is associated with conditions like Rheumatic Fever, Systemic Lupus Erythematosus, and Sjogren's syndrome.
• The absence of joint erosions differentiates it from rheumatoid arthritis.

Implications:

• Jaccoud's arthropathy in IgA vasculitis highlights the diverse rheumatological manifestations of the disease.
• Accurate diagnosis is essential as it is distinct from erosive arthropathies like rheumatoid arthritis.
• Management focuses on treating the underlying IgA vasculitis, as there is no specific treatment for Jaccoud's arthropathy itself.
