Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)
Key Points
Although symptoms of chronic inflammatory demyelinating polyneuropathy resemble those of Guillain-Barré syndrome, the two can be differentiated based on how long symptoms have continued to progress (ie, > 2 months for CIDP). Symptoms start insidiously and may slowly worsen or follow a pattern of relapses and recovery. CSF analysis and electrodiagnostic test results are similar to those of Guillain-Barré syndrome. Treat with IVIG and corticosteroids, but in severe cases, consider plasma exchange; immunosuppressants may help and can reduce dependence on corticosteroids.
