AB Plasma levels of complement (C) fragments iC3b, C4d, and Bb from human T
cell leukemia virus (HTLV)-positive subjects with HTLV-I-associated
myelopathy (HAM)/tropical spastic paraparesis (TSP) were analyzed by
EIA. Both iC3b and C4d levels were significantly elevated in persons
with HAM/TSP. These levels were similar to those in patients with human
immunodeficiency virus (HIV) infection or rheumatoid arthritis (RA), who
are known to have increased C fragments. Bb levels in persons with
HAM/TSP wer unaffected, suggesting that C activation occurred only via
the classical pathway. This differed from findings in HIV-infected or RA
patients, who had elevated levels of Bb. The results showed an increase
in C activation in persons with HAM/TSP and activation via the classical
pathway, likely mediated by virus or immune complexes. It is possible
that the C activation observed in these subjects contributed to the
inflammatory pathogenesis of HAM/TSP.
