Abstract
Background
Antiphospholipid syndrome (APS) is an acquired autoimmune disorder characterized by distinct pathophysiological mechanisms leading to heterogeneous manifestations, including venous and arterial thrombosis. Despite the lack of specific markers of thrombosis risk in APS, some of the mechanisms responsible for thrombosis in APS may overlap with those of other thromboembolic diseases. Understanding these similarities is important for improving the assessment of thrombosis risk in APS. MicroRNAs (MiRNAs) are RNA molecules that regulate gene expression and may influence the autoimmune response and coagulation.
Purpose
In this scoping review we aimed to investigate shared miRNAs profiles associated with APS and other thromboembolic diseases as a means of identifying markers indicative of a pro-thrombotic profile among patients with APS.
Data collection and Results
Through a comprehensive search of scientific databases, 45 relevant studies were identified out of 1020 references. miRs-124-3p, 125b-5p, 125a-5p, and 17-5p, were associated with APS and arterial thrombosis, while miRs-106a-5p, 146b-5p, 15a-5p, 222-3p, and 451a were associated with APS and venous thrombosis. Additionally, miR-126a-3p was associated with APS and both arterial and venous thrombosis.
Conclusion
We observed that APS shares a common miRNAs signature with non-APS related thrombosis, suggesting that miRNA expression profiles may serve as markers of thrombotic risk in APS. Further validation of a pro-thrombotic miRNA signature in APS is warranted to improve risk assessment, diagnosis, and management of APS.
