Controversies in lupus: nervous system involvement

Area of Science:

• Neurology
• Immunology
• Rheumatology

Background:

• Central Nervous System (CNS) lupus diagnosis and pathogenesis remain challenging.
• Antiphospholipid antibodies are implicated in CNS lupus, potentially causing microinfarctions.
• Current diagnostic tools for CNS lupus include neuropsychometric testing, quantitative EEG, and SPECT scans.

Purpose of the Study:

• To review recent advancements in understanding Central Nervous System (CNS) lupus.
• To discuss the role of antiphospholipid antibodies in the pathogenesis of CNS lupus.
• To highlight the diagnostic challenges and therapeutic shifts in managing CNS lupus.

Main Methods:

• Review of current knowledge on CNS lupus pathophysiology.
• Discussion of experimental models for antiphospholipid antibody syndrome.
• Analysis of diagnostic techniques and therapeutic strategies for CNS lupus.

Main Results:

• Significant progress in understanding antiphospholipid antibody pathophysiology in CNS lupus.
• Experimental models now exist for antiphospholipid antibody syndrome.
• Therapeutic focus is shifting from immunosuppression to anticoagulation for SLE patients.

Conclusions:

• Further research, including randomized trials, is crucial for optimizing anticoagulation therapy in CNS lupus.
• International collaboration is needed to establish clear patient categories and trial criteria.
• Improved understanding of pathogenesis may lead to better diagnostic and therapeutic approaches.
