We herein report the case of a 46 year old man with chronic inflammatory demyelinating polyneuropathy (CIDP) with hyperIgEaemia. The patient presented with bilateral weakness, generalized hyporeflexia, and mild paresthesia of the fingers of both hands. Nerve conduction studies revealed multiple sites of motor conduction block in the absence of sensory abnormalities. Muscle strength increased, as did compound muscle action potential (CMAP) amplitude immediately after the intravenous infusion of immunoglobulin (IVIg). Serum IgE levels also fluctuated in parallel with his relapsing-remitting clinical course. We propose that pure motor CIDP may be immune mediated and suggest that IgE-mediated allergy may be one potential cause of this condition.
