HIGH AND LOW DOSE IVIG THERAPY IN GUILLAINBARRE-SYNDROME CHILDREN: A COMPARISON

Acute inflammatory demyelinating peripheral neuropathy (GuillainBarre-Syndrome) is by far the most common cause of immune-medicated peripheral nervous system disease in children; with the near disappearance of poliomyelitis, GBS is responsible for the great majority of cases of acute flaccid paralysis. So far, in several controlled studies, corticosteroids, plasmapheresis and IVIG have been utilized in pediatric patients, afflicted with GBS. Regarding IVIG therapy, two methods have been used; the high dose (1 gr/kg/day for 2 days), and the low dose (400mg/kg/day for 5 days). Review of literature shows that a faster rate of recovery can be accomplished in patients who receive total dose of IVIG in 2 days as compared to the dose being given over 5 days. Materials & Methods: In this study we have compared these two types of treatment in an investigation, conducted in the Mofid Children Hospital on pediatric patients who had sudden onset of acute flaccid paralysis, and were diagnosed as having GBS. Based on histories, physical examination and electrodiagnosis, subjects were divided in two groups, the high dose IVIG treatment, 1gr/kg/day for 2 days (experimental group), and the low dose IVIG treatment, 400 mg/kg/day for 5 days (control group). Statistical analyses were then carried out using the appropriate software. Results: Result of this study showed a faster rate of recovery for patients in the high dose IVIG group; in this group duration of weakness of limbs was shorter and returning of DTR was faster than in controls. In fact, in this type of treatment, the relationship between high dose IVIG therapy and drug side effects was not significant. Conclusion: Base upon the finding in the present study, we conclude that the high dose IVIG therapy is superior to low dose, in view of faster duration of recovery and shorter hospital stay. Also we may infer that shorter hospital stay could be a factor in reducing of more nasocomial infection. In conclusion, we suggest using high dose IVIG treatment of choice in GBS.
