Investigation of the blood-brain barrier for IgG in inflammatory syndromes of the central nervous system.
To investigate whether an intravenously administered compound of the IgG class is able to penetrate the CSF barrier despite its high molecular weight, 12 hepatitis B surface antibody (anti-HBs)-negative patients received 20 ml each of a beta-propiolactone-treated IgG compound with a high anti-HBs titer (1:115,000) as a marker. 8 had an inflammatory CSF syndrome. In cases of inflammatory CSF syndromes, significantly more marked IgG crossed the blood-brain barrier, this could be of considerable clinical importance.
