- A 5-year retrospective study was undertaken in Children’s Postinfectious Autoimmune Encephalopathy Center at University of Arizona.
- 12 children diagnosed with PANS and treated with immunomodulatory IVIG dose who completed neuropsychological testing before and after treatment
- Participants received 1–7 IVIG courses.
- Improvement occurred in 11/12 patients, in one or multiple domains/subdomains, independently of time between disease onset and IVIG initiation (0–7 years)
- Improvement was primarily seen in memory (58%), sensory-motor (37%) and visual-motor integration (30%).
- 5/12 had hypogammaglobulinemia requiring ongoing IVIG replacement. Emphasizes the presumed role of immune dysfunction in disease pathogenesis.
- 1/12 had isolated low IgA. 1/12 discontinued IVIG therapy due to severe adverse effects
