- Abstract
Objectives Thrombosis occurring in the central nervous system is common in APS patients, leading to neuropsychiatric symptoms. We investigated the prevalence of silent brain abnormalities on MRI in primary APS (PAPS) patients and aPL carriers and assessed the association between the vascular risk factors, aPL profile, clinical manifestations and MRI abnormalities. Methods We consecutively included 44 PAPS patients, 24 aPL carriers and 23 healthy controls with comparable age and gender in a single-centre, observational, cross-sectional study. None of the patients had a history of stroke, transient ischaemic attack, migraine, dementia, epilepsy or bipolar disorders. On cerebral MRI, we assessed the imaging features and location of abnormality. Multivariate analysis was performed to identify the risk factors contributing to the MRI abnormalities. Results A total of 38 (55.88%) patients had abnormal MRI findings, while only one healthy control showed some abnormalities. Lacunes were the most frequent MRI abnormality in the aPL-positive group [31/68 (45.59%)], which were followed by white matter hyperintensities [20/68 (29.41%)]. In the study population, age [odds ratio (OR) 1.086, P = 0.016] and LA positivity (OR 5.191, P = 0.002) were independent associated factors with brain MRI abnormalities. When analysed in only the aPL-positive group, age (OR 1.116, P = 0.007), female gender (OR 7.519, P = 0.025) and thrombocytopenia (OR 8.336, P = 0.047) were the significant independent risk factors with abnormal MRI. Conclusions PAPS patients and aPL carriers showed a high prevalence of brain MRI abnormalities, indicating an increased cerebrovascular risk, which emphasized attention to silent cerebral lesions in persistently aPL-positive patients.
