Utility of neurophysiological criteria in Guillain Barre΄ syndrome: Subtype spectrum from a tertiary referral hospital in India|
Alexander, M; Prabhakar, A T.; Aaron, S; Thomas, M; Mathew, V & Patil, A K.
Background: The Guillain Barre' syndrome (GBS) is a heterogeneous disease with various subtypes, the prevalence of which would depend on the geographic region. Recognition of these subtypes is of clinical importance since each subtype has an independent pathogenesis and different type of pathology and prognosis.
Objectives: To study the various subtypes of GBS using the various published electrophysiological criteria.
Design: Retrospective descriptive study.
Materials and Methods: In a tertiary care hospital setting, the study compared the various published criteria for demyelination in GBS. The charts of 115 consecutive patients referred for electrodiagnostic evaluation to the Electromyography laboratory between July 2000 and June 2006 were reviewed.
Results: Of the 115 patients, 51 (44.4%) patients had axonal forms of GBS and 44 (38.2%) patients had acute inflammatory demyelinating polyradiculoneuropathy (AIDP). Applying the various published criteria, the number of patients categorized under the AIDP subtype ranged between 23.4% and 67.2%.
Conclusion: In this study 44% patients had axonal forms of the disease, 38.2% patients had AIDP subtype and 17% remained unclassified. The most sensitive criteria to identify AIDP were the criteria proposed by Albers and colleagues and the Dutch group.
