OBJECTIVE: To search for a relationship between serum anti-beta2
glycoprotein I (anti-beta2GPI) antibodies and the occurrence of ischaemic
complications in giant cell arteritis (GCA), since the latter do not
correlate with anti-cardiolipin antibodies (ACL), which are frequently
observed in GCA. METHODS: IgG and IgM anti-beta2GPI antibodies and ACL were
measured by enzyme-linked immunosorbent assays in sera, collected before
treatment, from 45 unselected patients with biopsy-proven GCA, including 15
patients with ischaemic events. RESULTS: IgG and IgM anti-beta2GPI
antibodies were not detected in any of the patients, contrasting with the
presence of ACL in 51%, of them, without correlation with ischaemia.
CONCLUSION: Anti-beta2GPI antibodies are not detectable in GCA, contrasting
with the occurrence of ACL, and ischaemic complications are apparently
unrelated to the most frequent anti-phospholipid antibodies.
