Summary
Beta-2 microglobulin (β2M) serum levels are elevated in patients with active Systemic Lupus Erythematosus (SLE). This finding highlights β2M as a potential biomarker for assessing SLE disease activity.
Area of Science:
- Rheumatology
- Immunology
- Clinical Chemistry
Background:
- Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease characterized by unpredictable flares.
- Accurate assessment of SLE clinical activity is crucial for effective treatment management.
Purpose of the Study:
- To investigate the diagnostic value of serum beta-2 microglobulin (β2M) levels in determining the clinical activity of Systemic Lupus Erythematosus (SLE).
Main Methods:
- A cross-sectional study involving 129 SLE patients.
- Disease activity was assessed using SLEDAI and SLICC ACR indices.
- Serum levels of β2M, ESR, anti-dsDNA antibodies, and complement fractions (C3, C4) were measured.
Main Results:
- Serum β2M levels showed a positive correlation with SLEDAI and ESR, indicating higher activity.
- A negative correlation was observed between β2M and C3 levels.
- Patients with positive anti-dsDNA antibodies exhibited significantly higher β2M levels.
Conclusions:
- Elevated serum β2M levels are associated with active disease in SLE patients.
- β2M shows potential as a biomarker for monitoring SLE disease activity.
