RT Journal Article SR Electronic T1 Detection of IgG anti-beta2 glycoprotein-I antibodies in Saudi patients with systemic lupus erythematosis JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 594 OP 599 VO 29 IS 4 A1 Alenzi, Faris Q. YR 2008 UL http://smj.org.sa/content/29/4/594.abstract AB OBJECTIVE: To develop an assay for the measurement of this anti-human beta2-glycoprotein I a-beta2-GPIMETHODS: This study was conducted from September 2004 to December 2006. The patients attending the Rheumatology Clinic were chosen from several centers in the Eastern region of Saudi Arabia because they had complications. An enzyme-linked immunosorbent ELISA assay was optimized and developed to measure IgG a-beta2-GPI antibody levels in humans. Fifty normal blood donors and 50 systemic lupus erythrematosis SLE patients were selected for this experiment.RESULTS: Raised IgG a-beta2-GPI antibody levels were found in 80% of SLE patients. Interestingly, raised IgG a-beta2-GPI antibody levels were associated with the presence of venous thrombosis and thrombocytopenia.CONCLUSION: The real value of IgG a-beta2-GPI as a predictor for the future clinical complications needs to be confirmed in prospective controlled studies investigating clinical complications in relationship to IgG a-beta2-GPI and to other risk factors for thrombosis.
