Coexistence of Type B Insulin Resistance and Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) in Type ۲ Diabetes Mellitus: Various Manifestations With the Same Pathophysiologic Base?

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rarely reported disease. The association between diabetes mellitus (DM) and CIDP has been a matter of controversy. Here we presented a ۵۹-year old male patient with uncontrolled type ۲ DM presented with simultaneous type B insulin resistance (TBIRS) and CIDP. Both blood glucose and neurological manifestations responded well to corticosteroid therapies. Although the pathogenesis of CIDP remains to be elucidated, the role of antibodies in the pathogenesis of TBIRS and CIDP might be a promising platform for further studies to provide additional insights into the origin of these ۲ rare complications.
