ABSTRACT

OBJECTIVES: Intravenous immunoglobulin (IVIg) is used for treatment of acute neurologic conditions such as Guillain-Barre syndrome, chronic inflammatory demyelinating polyradiculoneuropathy relapse, and myasthenia gravis exacerbation. Precision dosing (adjusted or ideal body weight) is proposed to conserve IVIg. There have been no published studies comparing clinical outcomes in traditional dosing (actual body weight) with precision dosing. In 2014, our institution began dosing patients with precision dosing. This decision was largely performed by administration rather than physicians' preference. We sought to analyze our retrospective data to understand the change in dosing methods with neurologic outcomes.

METHODS: We performed a retrospective review of all patients hospitalized at a single center who received IVIg for myasthenia gravis, Guillain-Barre syndrome, and chronic inflammatory demyelinating polyradiculoneuropathy from January 2010 to October 2017. We collected baseline information and clinical outcomes including mortality, readmission, need for second rescue treatment, length of stay, discharge disposition, treatment-related adverse events, and modified research council posttreatment sum score.

RESULTS: Length of stay was significantly shorter with precision dosing. There was no statistically significant difference in discharge disposition, readmission, rescue treatment, or modified research council posttreatment sum score with precision dosing.

CONCLUSION: Precision dosing did not adversely affect short-term neurologic outcomes.
