Differentiation Between Guillain-Barre Syndrome and Acute-Onset Chronic Inflammatory Demyelinating Polyradiculoneuritis-a Prospective Follow-up Study Using Ultrasound and Neurophysiological Measurements.

ABSTRACT: Differentiation of Guillain-Barré syndrome (GBS) and acute-onset chronic inflammatory demyelinating polyradiculoneuritis (CIDP) might be intricate in early stages. We compared electrodiagnostics (EDx) and nerve ultrasound (NUS) as tools for early distinction and follow-up. NUS and EDx have been performed at first visitation and after 6 months. The nerve conduction study score (NCSS), the ultrasound pattern sum score (UPSS), and clinical scores were used for comparison. Compared with the 33 GBS patients, the 34 CIDP patients (50% with symptoms < 4 weeks) revealed significant nerve enlargement in ultrasound (p < 0.001) except for the roots and vagus, which exhibited increased values in both groups. EDx has no significant differences between both groups except for the A-wave frequency and the
