Abstract
The terminal complement complex (TCC) was determined in plasma and cerebrospinal fluid
(CSF) from 208 neurological patients. Elevated CSF TCC levels were observed in higher
frequencies in patients with infectious diseases (80%), radiculoneuritis (62%), multiple
sclerosis (30%), and miscellaneous autoimmune diseases (27%) than in patients with
miscellaneous non-inflammatory diseases (2–13%). The plasma level of TCC was significantly
increased only in the infectious group. No positive correlation was observed between
the plasma and the CSF TCC concentration in the whole patient population nor in subgroups
divided according to blood-brain barrier function. Furthermore, the CSF TCC concentration
did not correlate with the serum/CSF albumin ratio or with CSF total protein concentration
when this was below 1.0 g/l. It is concluded that an elevated TCC concentration in
CSF reflects intrathecal complement activation and that quantification of TCC in CSF
may be a valuable supplement in the examination of neurological diseases.
