Data are shown as median (5th– 95th percentile) unless specified otherwise. # % IgGIF according to Reiber (Reiber H. J Neurol Sci. 1994;122:189–203) and Auer & Hegen (Auer M, Hegen H et al. Eur J Neurol. 2016;23:713–721) formulae was 62% and 66%, respectively, in the single patient of the IND group. Clinical diagnosis of this patient was HIV encephalopathy.
