We evaluated occurrence and levels of intrathecal synthesis of IgG, IgM, IgA and IgD by calculating corresponding index values in 8 patients with definite and 4 with suspected or possible neurosyphilis, prior to, during and after high‐dose intravenous penicillin therapy. Four patients with active neurosyphilis displayed intrathecal synthesis of IgG, IgM and IgA. Only 2 of them showed elevated IgD index, and both had taboparesis, pleocytosis and positive VDRL in CSF, and simultaneous elevation of the IgG, IgA and especially of the IgM indices. This suggests that intrathecal synthesis of IgD may occur in patients with severe CNS inflammation in response to diffuse CNS treponemal damage. Penicillin therapy incited transitory elevation of one or more of the immunoglobulin index values in most patients, possibly in response to massive treponemal lysis inside the CNS. Thereafter, the values became mostly normalized but exceptions occurred, including one patient who had elevated IgG and IgM index which persisted 31 months after therapy. Our data indicate that determinations of immunoglobulin indices performed on consecutive specimens from individual patients with neurosyphilis may be helpful in the evaluation of treatment.
