Antiphospholipid antibody positivity in early systemic lupus erythematosus is associated with subsequent vascular events.

ABSTRACT:

Objective

aPL are found in the blood of 20-30% of patients with SLE. Although aPL cause vascular thrombosis in the antiphospholipid syndrome, it is not clear whether positive aPL levels in early SLE increase risk of subsequent vascular events (VE). In a previous analysis of 276 patients with SLE, we found that early positivity for ≥2 of IgG anti-cardiolipin (anti-CL), IgG anti-β2-glycoprotein I (anti-β2GPI) and anti-domain I of β2-glycoprotein I (anti-DI) showed a possible association with VE. Here we have extended that analysis.

Methods

Serum samples taken from 501 patients with SLE early in their disease had been tested for IgG anti-CL, anti-β2GPI and anti-DI by ELISA. Complete VE history was available for 423 patients of whom 23 were excluded because VE occurred before th
