What mechanisms explain IVIg's protective effect against respiratory infections in AD patients?

OPEN

IVIg-treated participants had fewer respiratory infections than placebo controls, an unexpected finding not directly related to AD pathology. This observation suggests potential immunomodulatory effects that warrant investigation, especially given the emerging role of infections in AD progression. Gap type: unexplained_observation Source paper: A phase 3 trial of IV immunoglobulin for Alzheimer disease. (2017, Neurology, PMID:28381506)
