Lupus nephritis in a neuronal storage disease

Area of Science:

• Nephrology
• Neurology
• Rheumatology

Background:

• Systemic lupus erythematosus (SLE) is a complex autoimmune disease.
• Glomerulonephritis is a common and serious renal manifestation of SLE.
• Neuronal storage diseases are a group of rare genetic metabolic disorders.

Observation:

• A patient with a long-standing neuronal storage disease and myoclonus presented with SLE and glomerulonephritis.
• Myoclonus, a neurological symptom, complicated the diagnostic process.
• Intravenous diazepam administration was employed to manage the myoclonus.

Findings:

• Diazepam successfully controlled the patient's myoclonus.
• The myoclonus control facilitated the performance of a renal biopsy.
• The renal biopsy was essential for diagnosing glomerulonephritis in the context of SLE.

Implications:

• This case highlights the complex interplay between rare genetic disorders and autoimmune conditions.
• Effective symptomatic management (e.g., diazepam for myoclonus) can be critical for diagnosing co-existing conditions.
• The underlying mechanisms linking neuronal storage diseases and SLE development require further investigation.
