Summary
Systemic lupus erythematosus (SLE) involves autoantibodies targeting nucleosomes, leading to inflammation. Morphologic diagnosis of biopsies aids in assessing disease activity and guiding treatment for SLE and antiphospholipid syndrome (APS).
Area of Science:
- Immunology
- Pathology
Context:
- Systemic lupus erythematosus (SLE) is a chronic autoimmune disease.
- Nucleosomes are key antigens driving SLE pathogenesis.
- Drug-induced SLE involves DNA hypomethylation and altered immune cell interactions.
Purpose:
- To elucidate the mechanisms of autoreactivity in SLE.
- To highlight the role of apoptosis disturbances in SLE.
- To emphasize the diagnostic and prognostic value of morphologic analysis in SLE and antiphospholipid syndrome (APS).
Summary:
- SLE is characterized by antinuclear antibodies, with nucleosomes as primary antigens.
- Mechanisms include DNA hypomethylation, altered immune cell binding, and apoptosis dysregulation.
- Morphologic diagnosis of skin and renal biopsies, including activity and chronicity scores, is crucial for SLE management.
- Antiphospholipid syndrome (APS), often secondary to SLE, involves thrombosis and antiphospholipid antibodies, potentially linked to inhibited protein C activity.
Impact:
- Morphologic assessment aids in diagnosis, prognosis, and therapeutic decisions for SLE.
- Understanding SLE and APS mechanisms can inform future therapeutic strategies.
- This review synthesizes key aspects of SLE and APS pathogenesis and diagnosis.
