Pseudotumor cerebri in systemic lupus erythematosus

Area of Science:

• Neurology
• Rheumatology
• Pathology

Background:

• Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with diverse clinical manifestations.
• Pseudotumor cerebri (PC), also known as idiopathic intracranial hypertension, is characterized by increased intracranial pressure without a clear cause.
• The potential association between SLE and PC requires further investigation to understand underlying mechanisms.

Observation:

• A review of 13 articles and analysis of 21 patients revealed coexisting PC and SLE.
• Patients with both conditions often presented with severe SLE, including significant renal involvement (79%) and proteinuria (47%).
• A hypercoagulable state, indicated by thromboembolic events or high anti-cardiolipin antibody titers, was observed in 58% of these patients.

Findings:

• The co-occurrence of PC and SLE suggests a link beyond chance.
• The high prevalence of hypercoagulability in patients with both SLE and PC points to a potential pathogenic role.
• Microthromboembolic events are hypothesized to contribute to the development of PC in the context of SLE.

Implications:

• This association highlights the importance of considering PC in SLE patients, especially those with severe disease or hypercoagulable states.
• Understanding the role of hypercoagulability may lead to novel therapeutic strategies for preventing or managing PC in SLE.
• Further research into the specific mechanisms linking autoimmune disease, hypercoagulability, and intracranial hypertension is warranted.
