CIDP is a most common chronic immune-mediated demyelinating neuropathy, but still a rare disease; the reported prevalence ranges from 0.8 to 8.9 per 100 000 people.1 The different prevalence among the studies is partly dependent on diagnostic criteria and CIDP subtypes. Currently, diagnostic criteria proposed by Joint Task Force of the European Federation of Neurological Societies and the Peripheral Nerve Society (EFNS/PNS) are generally used, and the guideline also classified CIDP into the clinical subtypes; ‘typical CIDP’, and ‘atypical CIDP’ included multifocal CIDP (Lewis-Sumner syndrome), distal CIDP (distal acquired demyelinating symmetric) and other variants.2 Separately the association of CIDP and diabetes mellitus has been a matter of controversy. So far, at least four studies on the association have been published (table 1 …
