Summary
Primary hypogammaglobulinaemia can present as arthritis, particularly in Bruton's disease. Early diagnosis of this immunodeficiency is crucial to prevent recurrent infections and associated joint complications.
Area of Science:
- Immunology
- Rheumatology
- Pediatrics
Background:
- Primary hypogammaglobulinaemia is a group of inborn errors of immunity.
- Arthritis can be an early, and sometimes the sole, presenting clinical feature of primary hypogammaglobulinaemia.
- Distinguishing immunodeficiency-related arthritis from other arthropathies is critical for appropriate management.
Observation:
- In a cohort of 281 immunodeficiency patients over 16 years, 30 (10.7%) presented with arthritis.
- Arthritis was significantly more common in Bruton's disease (22%) compared to other forms of immunodeficiency (7%).
- Non-septic arthritis predominated, with monoarticular patterns in Bruton's disease and pauciarticular involvement in common variable immunodeficiency.
Findings:
- Arthritis at presentation is a notable feature in primary hypogammaglobulinaemia.
- Bruton's disease shows a higher incidence of arthritis at diagnosis than other immunodeficiencies.
- Delayed diagnosis in boys with Bruton's disease is linked to recurrent infections complicated by arthritis.
Implications:
- Serum immunoglobulin measurement is a key diagnostic tool to differentiate immunodeficiency-related arthritis from conditions like Still's disease.
- Timely diagnosis and management of primary hypogammaglobulinaemia can prevent severe complications, including infectious arthritis.
- This highlights the importance of considering immunodeficiency in the differential diagnosis of unexplained arthritis, especially in pediatric males.
