abstract = {To comprehensively characterize complement pathway
activation in chronic inflammatory demyelinating
polyneuropathy (CIDP) and its association with clinical
disease features using advanced complement
profiling.Complement protein levels indicative of classical,
lectin, and alternative pathway activation were quantified
by multiplex ELISA and compared between 28 patients with
typical CIDP, 24 patients with Charcot-Marie Tooth
neuropathy (CMT), and 24 demographically matched healthy
controls (HD).Serum levels of activated complement
proteins-C3a, C4a, Ba, Bb, C5a, and the soluble terminal
complement complex sC5b-9 (sTCC)-were significantly elevated
in CIDP patients compared to healthy donors (HD) (p <
0.001). Except for C3a, these protein levels were also
significantly higher in CIDP patients than in those with
Charcot-Marie-Tooth disease (CMT). Among CIDP patients,
those with active, unstable disease exhibited significantly
higher levels of terminal complement components (C5a and
sTCC) compared to patients with stable disease or in
remission (p < 0.001).These findings highlight the critical
involvement of aberrant complement activation in the
pathophysiology of CIDP and provide a rationale for further
investigation into targeted complement inhibition as a
therapeutic approach.},
