Anti-β2-glycoprotein I autoantibody expression as a potential biomarker for strokes in patients with anti-
phospholipid syndrome

A
nti-phospholipid syndrome (APS) is an autoimmune disease. Cerebral ischemia associated with APS occurs at a younger age than
typical atherothrombotic cerebrovascular disease, is often recurrent, and is associated with high positive IgG anti-phospholipid
(GPL) unit levels. This study sought to determine the frequency rates of anti-cardiolipin (aCL) dependent on the presence of β
2
-GPI,
anti-β
2
-glycoprotein I (aβ
2
-GPI) and anti-phosphatidyl serine (aPS) IgG autoantibodies among stroke patients, and thus demonstrate
the importance of testing for aβ
2
-GPI autoantibodies. For this study, stroke patients and control subjects recruited from Mosul, Erbil
and Dohuk provinces in Northern Iraq between March 2004 and March 2005 were evaluated. All cases were under 50 years-of-age
and had no recognizable risk factors. Using ELISA to evaluate the presence of IgG isotype of aCL, aβ
2
-GPI and aPS autoantibodies
in their blood, the results indicated that the frequency of aβ
2
-GPI was 14/50 (28%), aCL was 11/50 (22%), and aPS was 9/50 (18%)
among stroke patients. In contrast, aCL was detected in 2/30 (6.7%) of control subjects; each of the other anti-phospholipid antibodies
(APLA) was never observed. Of all the aβ
2
-GPI+ cases, the incidence of stroke patients having the combined profile of aβ
2
-GPI +
aCL was 11/14 (78.6%) and of aβ
2
-GPI + aPS was 9/14 (64.3%). Only 2/14 (14.3%) of these aβ
2
-GPI+ patients, also expressed aCL in
the absence of aPS. The frequency of patients expressing all three markers was only 9/14 (64.3%). In none of the APS/stroke patients
were aCL or aPS expressed in the absence of the aβ
2
-GPI. Conversely, IgG aβ
2
-GPI as a sole marker was seen in 3/14 (21.4%) of these
patients (i.e. in absence of either other marker). It can be concluded from these studies that the among the three major forms of APLA
examined, the presence of IgG aβ
2
-GPI autoantibodies appeared to correlate best with stroke in patients who were concurrently
suffering APS.
