Clinical Scorecard: Clinical Case Study: Coexisting Multiple Sclerosis and Neuropsychiatric Systemic Lupus Erythematosus with Positive MOG-IgG in a Patient Initially Diagnosed with Depression

At a Glance

CategoryDetail
ConditionMultiple Sclerosis and Neuropsychiatric Systemic Lupus Erythematosus
Key MechanismsAutoimmune mechanisms affecting the central nervous system, with positive MOG-IgG and various autoantibodies.
Target PopulationAdults with overlapping autoimmune CNS disorders.
Care SettingTertiary neurology center

Key Highlights

  • Patient initially misdiagnosed with major depressive disorder.
  • Developed progressive gait instability and cognitive decline.
  • Final diagnosis established as coexisting MS and NPSLE.
  • Positive MOG-IgG at a titer of 1:32.
  • Clinical improvement observed after treatment with glucocorticoids and hydroxychloroquine.

Guideline-Based Recommendations

Diagnosis

  • Utilize the 2017 McDonald criteria for MS diagnosis.
  • Apply the 2019 EULAR/ACR classification criteria for NPSLE.

Management

  • Initiate treatment with glucocorticoids and hydroxychloroquine.
  • Continue psychiatric care with antidepressants.

Monitoring & Follow-up

  • Regular follow-up to assess mood, cognitive function, and gait stability.

Risks

  • Diagnostic challenges due to overlapping symptoms of MS and NPSLE.

Patient & Prescribing Data

Older adults with psychiatric symptoms and neurological decline.

Combination therapy with glucocorticoids and hydroxychloroquine can lead to clinical improvement.

Clinical Best Practices

  • Conduct comprehensive clinical and laboratory evaluations for patients with psychiatric symptoms and neurological signs.
  • Consider autoimmune testing in patients with unexplained neurological symptoms.
