Neuropsychiatric Systemic Lupus Erythematosus Diagnosis and Management

Introduction to NPSLE

The patient's SLE was likely present subclinically before topiramate was started, with neuropsychiatric manifestations emerging as the disease declared itself, according to the European League Against Rheumatism (EULAR) guidelines 1, 2

Seizures are a common NPSLE manifestation with a cumulative incidence of 5-15%, and they frequently occur within the first year after SLE diagnosis, as stated by the American College of Rheumatology 1, 2
Previous or concurrent severe NPSLE manifestations, including seizures, are strong risk factors (at least fivefold increased risk) for subsequent NPSLE events, according to the European League Against Rheumatism (EULAR) guidelines 1
Most seizures in SLE represent single isolated events, though recurrent seizures occur in 12-22% of cases, as reported by the American College of Rheumatology 3

Lumbar puncture with comprehensive CSF analysis including cell count, protein, glucose, Gram stain, culture, and viral PCR to exclude infection, as recommended by the European League Against Rheumatism (EULAR) guidelines 2, 4
MRI brain with conventional sequences, diffusion-weighted imaging, and gadolinium-enhanced T1 sequences, as suggested by the American College of Rheumatology 1, 2

Before diagnosing lupus-related aseptic meningitis, infectious causes must be rigorously excluded, especially in immunosuppressed patients, according to the European League Against Rheumatism (EULAR) guidelines 2
If the meningitis was truly NPSLE-related, glucocorticoids and immunosuppressive therapy would be indicated following exclusion of infection, as stated by the American College of Rheumatology 5, 2
The agreement score of 9.6 from EULAR guidelines emphasizes the critical importance of excluding non-SLE causes before attributing meningitis to lupus, as reported by the European League Against Rheumatism (EULAR) guidelines 2

The seizures should be managed as NPSLE with appropriate antiepileptic drugs (avoiding topiramate) and treatment of underlying SLE activity, as recommended by the American College of Rheumatology 3, 5
If seizures are thought to reflect acute inflammatory events or occur with concurrent lupus flares, glucocorticoids alone or combined with immunosuppressive therapy should be given, according to the European League Against Rheumatism (EULAR) guidelines 3
Monitor for seizure recurrence, as previous severe NPSLE manifestations are strong risk factors for subsequent events, as stated by the American College of Rheumatology 1
Alternative migraine prophylaxis options include amitriptyline, valproate, or gabapentin if migraine prevention is still needed, as suggested by the American Headache Society 6
