[Dysimmune neuropathies: current diagnosis and therapy].

Dysimmune neuropathies encompass an acute form, Guillain-Barré syndrome (GBS), and mainly 3 chronic forms: chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multifocal motor neuropathy, and polyneuropathy associated with anti-MAG (myelin-associated-glycoprotein) IgM monoclonal gammopathy. Recent concepts have concerned both incidence and mortality rates, and better scoring system for predict outcome in GBS, but new therapeutical strategy is needed for the so-called "benign" forms and for relapsing forms after first-line IVIg therapy. In chronic forms, criteria for diagnosis and guidelines for management have been edited in the recent years, together with recommendations for outcome measures. However, there is still a need for knowing the better outcome measures, and to elaborate new trials, mainly focusing on the long-term management of the patients.
