Chronic Inflammatory Demyelinating Polyneuropathy After Therapy With Infliximab Biosimilar.

Tumor necrosis factor-α inhibitors are monoclonal antibodies that are commonly used in the treatment of inflammatory bowel disease. A rare side effect of these biological agents is chronic inflammatory demyelinating polyneuropathy, which is a debilitating disease characterized by weakness, sensory dysfunction, and diminished or absent reflexes. We present the first reported case of chronic inflammatory demyelinating polyneuropathy after treatment with the tumor necrosis factor-α inhibitor biosimilar, infliximab-dyyp (Inflectra).
