Diagnosis and treatment of vasculitis of the central nervous system in a patient with systemic lupus erythematosus.
BACKGROUND
A 23-year-old white woman with a 3-year history of systemic lupus erythematosus and a 15-month history of lupus nephritis and retinal vasculitis was successfully treated with antibiotics for Pseudomonas aeruginosa pneumonia while on moderate doses of corticosteroids. Even though her pneumonia had improved, she developed acute changes in her mental status that rapidly progressed to encephalopathy with coma.


METHODS
Physical examination, fundoscopic examination, laboratory tests for metabolic abnormalities, cerebrospinal fluid analysis, microbiology and serologic testing, electroencephalogram, tests for IgM and IgG anticardiolipin antibodies, neuroimaging including CT of the brain and T1-weighted MRI before and after gadolinium contrast, and flow-attenuated inversion recovery MRI.


METHODS
Vasculitis of the central nervous system associated with systemic lupus erythematosus.


RESULTS
Intravenous methylprednisolone 1,000 mg/day for 3 days, one dose of intravenous pulse cyclophosphamide 750 mg/m(2), intravenous immunoglobulin 400 mg/kg/day for 4 days, plasmapheresis on alternate days for five cycles, and prednisone 40 mg/day. She continued monthly doses of intravenous pulse cyclophosphamide and intravenous pulse methylprednisolone for 6 months, followed by maintenance infusions every 3 months over 2 years. Prednisone was tapered over 18 months. Cyclophosphamide was discontinued after 2 years because of poor bone-marrow tolerance, and was replaced with mycophenolate mofetil 3,000 mg/ day and ciclosporin 50 mg twice daily.
