Rheumatoid Disease in Children.

Area of Science:

• Pediatric Rheumatology
• Clinical Immunology
• Rheumatic Diseases

Background:

• Infantile rheumatoid arthritis (IRA) is a rare autoimmune condition affecting children.
• The systemic nature and variable presentation of IRA pose significant diagnostic challenges.
• Early identification is critical for managing the disease and preventing long-term disability.

Purpose of the Study:

• To analyze clinical data from patients diagnosed with IRA between 1940 and 1960.
• To investigate the early clinical manifestations and diagnostic difficulties associated with IRA.
• To correlate initial joint involvement with final pathology and assess prognostic factors.

Main Methods:

• Retrospective analysis of 102 patient cases diagnosed with IRA.
• Evaluation of initial symptoms, joint involvement patterns, and disease progression.
• Assessment of diagnostic methods, including clinical evaluation and laboratory tests.
• Follow-up analysis to determine functional outcomes and long-term disability.

Main Results:

• Only 20% of patients presented with articular symptoms at onset; the youngest was 6 months old.
• Swollen proximal interphalangeal joints (spindle fingers) are late but diagnostic signs.
• Diagnosis is primarily clinical, with laboratory tests showing limited diagnostic value.
• Prognosis is influenced by age of onset, therapy initiation, and systemic involvement.

Conclusions:

• IRA's early diagnosis is difficult due to non-specific systemic symptoms.
• Clinical assessment remains paramount for diagnosing IRA.
• Functional outcomes vary, with 50% achieving normal function, 25% mild disability, and 25% severe disability at follow-up.
