Jaccoud arthritis

Area of Science:

• Rheumatology
• Clinical Medicine

Background:

• Jaccoud polyarthritis is a rare complication of rheumatic fever, characterized by severe, recurrent attacks.
• It presents as a painless, deforming arthritis of the small joints in the hands and feet, potentially with metacarpal head erosion.
• Established cases typically show significant rheumatic heart disease.

Purpose of the Study:

• To investigate the clinical and radiographic features of Jaccoud arthropathy.
• To explore potential diverse etiologies beyond rheumatic fever.

Main Methods:

• Case review of patients presenting with clinical and radiographic features of Jaccoud arthropathy.
• Assessment of patient history for antecedent rheumatic fever.

Main Results:

• Two patients exhibited Jaccoud arthropathy features without a prior history of rheumatic fever.
• Radiological findings consistent with Jaccoud arthropathy were observed.

Conclusions:

• Jaccoud arthropathy may present in individuals without a history of rheumatic fever.
• The condition potentially has diverse underlying causes beyond rheumatic fever.
