Initial CSF protein predicts treatment response in chronic inmmune mediated demyelinating polyneuropathy (CIP)

Background: Chronic inflammatory demyelinating polyneuropathy (CIDP) is a heterogenous disease of probably autoimmune origin. Recently published criteria give consideration to its clinical heterogeneity as well as to the impact of positive treatment response in making the diagnosis ex iuvantibus. Beyond intravenous immunoglobulins (IVIg), steroids, azathioprine, mycophenolate, ciclosporine, cyclophosphamide or plasma exchange are accepted as standard or escalating treatment options. Objective: To define the positive predictive value for treatment response of elevated cerebrospinal fluid (CSF) protein in CIDP pat…
