Major finding: Six of eight people (75%) with leucine-rich, glioma-inactivated-1 antibody–associated epilepsy had at least a 50% reduction in seizure frequency with IVIG, versus none of six randomized to placebo.

Study details: Controlled clinical trial involving 17 patients.

Disclosures: The work was funded by companies that sell IVIG and IVIG home infusion equipment. The study lead disclosed research support from the IVIG maker, and another investigator is a consultant for the company.
