Guillain-Barré syndrome as a prominent cause of childhood acute flaccid paralysis in post polio eradication era in Egypt.

Guillain-Barré syndrome often follows an antecedent gastrointestinal or respiratory illness but, in rare cases, follows vaccination. This study was conducted to identify preceding events, demographic, clinical characteristics and prognostic factors of childhood Guillain-Barré syndrome after post-poliomyelitis eradication era in Egypt. This is a prospective study of all children with GBS (no = 50) admitted to pediatric Cairo University Hospital between January 2006 and June 2007 (70.42% of all acute flaccid paralysis patients during this period). Upper respiratory infection was the most common preceding event (24%) while only 4 patients (8%) reported antecedent oral polio vaccine. Motor deficit was frequent and severe (quadriparesis in 92% and paraparesis in 8%). Autonomic dysfunction was recorded in 32% of patients. Forty two percent of patients had poor outcome with 16% deaths. Presence of severe disability on admission and on nadir, cranial nerve affection or the need for mechanical ventilator were found to be significant predictors for poor outcome.
