Intravenous immunoglobulin vs plasma exchange in treatment of mechanically ventilated adults with Guillain-Barré syndrome

Abstract

INTRODUCTION: The aim of the study is to compare efficacy of IvIg versus PE in treatment of mechanically ventilation adults with GBS in intensive care unit. METHODS: It is a prospective, non randomized study, realized in a medical ICU from 2006 to 2010. We included all patients with GBS who required mechanical ventilation (MV). We defined two groups: group 1 (group treated by IvIg: 0.4 g/kg/day for 5 days) and group 2 (group treated by PE: 4 PE during 10-14 days). We collected demographic characteristics, clinical and therapeutic aspects and outcome. Statistical analysis used: The quantitative variables are expressed on mean , standard derivation and compared by Student test. The statistic analysis has been based on SPSS for windows. P = 0.05 is considered as significant. RESULTS: Forty-one patients (21 in group 1 and 20 in group 2) were enrolled. The mean age was 37.4 , 9.2 years, with a masculine predominance (75.4%). Electromyogram in all patients found acute inflammatory demyelinating polyradiculoneuropathy in 80.5 % of patients. The mean length of hospitalization was 45.3 9.2 days. The length of hospitalization of the IvIg group is less long than PE group (p = 0.03). The weaning of the MV was more precocious in IvIg group than PE group (p = 0.01). Also, the beginning of motility recuperation was precocious at IvIg group than PE group (p = 0.04). CONCLUSION: Our work reveals a meaningful difference for the MV weaning and precocious recovery in IvIg group compared to PE group.
