Systemic Lupus Erythematosus With Acute Inflammatory Demyelinating Polyneuropathy: A Case Report and Review of the Literature

摘要

We recently encountered a patient with acute inflammatory demyelinating polyneuropathy (AIDP) that was associated with systemic lupus erythematosus (SLE). A 34-year-old Chinese female with a 3-year history of SLE presented with acute bilateral leg weakness and paraparesis, and lost the ability to walk 1 day after noticing bilateral leg numbness and pain for 12 days. Physical examination revealed bilateral facial muscle paralysis, muscle strength in the legs with graded 1/5 proximally and 2/5 distally bilaterally and absence of deep tendon reflex in both knees and ankles. Paresthesia was observed in distal limbs with glove and stocking distribution. Cerebrospinal fluid analysis demonstrated albuminocytologic dissociation. Electrophysiologic survey also indicated sensory-motor demyelinating polyneuropathy. The diagnosis of SLE was established based on her initial symptoms including intermittent fevers, hair loss, oral ulcers, malar rash and arthritis affecting the elbow, wrist and hand joints; positive immunologic findings for antinuclear antibody (ANA), anti-DNA antibody, anti-Smith (anti-Sm) antibody, low serum complement levels, and the kidney biopsy specimen showed glomerular mesangial proliferation with focal endothelial cell proliferation (ISN/PPS 2004 classification lupus nephritis, class III). Treatment with intravenous immunoglobulin, methylprednisolone and cyclophosphamide resulted in clinical and electrophysiological improvement.J Clin Med Res. 2016;8(7):555-559doi: http://dx.doi.org/10.14740/jocmr2550w
