Diagnosis and treatment of CIDP: a "grand cru" of updated data.

Eur J Neurol 2021 Jun 21. Epub 2021 Jun 21.

Department and Laboratory of Neurology, National Reference Center for 'rare peripheral neuropathies', University Hospital of Limoges (CHU Limoges), Dupuytren Hospital, 2 avenue Martin Luther King, 87042, Limoges, France.

At present there are no specific tests for the definitive diagnosis of Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), but numerous diagnostic criteria have been published over the last decades. It is generally recognized that the EFNS/PNS criteria (published in 2010) have the best sensitivity with a good specificity. Nevertheless, even now, many patients are over-diagnosed with CIDP, leading to an unnecessary risk of adverse events and extra-cost, and on the other hand, some CIDP patients are unfortunately not diagnosed who could have benefited from effective treatment.
