Frequency of axonal variants of guillain-barre syndrome in Pakistan

ABSTRACT

To determine the frequency of axonal variants in our patients of Guillain-Barre Syndrome. Descriptive study. Department of Neurology, Military Hospital, Rawalpindi and Armed Forces Institute of Rehabilitation Medicine [AFIRM] from 01 Jan 2009 to 30 Jul 2010. Forty adult patients meeting the National Institute of Neurological Disorders and Stroke criteria for Guillain-Barre Syndrome [GBS] were consecutively enrolled in the study. Patient's data, detailed history, examination and electrophysiological studies were carried out and recorded on predesigned proforma. All patients were examined and reviewed by Consultant Physicians and neurologists. Electromyography and Nerve conduction study testing was done by experienced electro-physiologists. Axonal variants of Guillain-Barre Syndrome constituted 16[40%] in our study. The variants of Guillain-Barre syndrome were acute inflammatory polyradiculoneuropathy [AIDP] in 24[60%] patients followed by acute motor axonal neuropathy [AMAN] in 12[30%] and acute motor sensory axonal neuropathy [AMSAN] in 4[10%] patients. We report a high frequency of the axonal variants of Guillain-Barre Syndrome in Pakistan
