Impact of markers of endothelial injury and hypercoagulability on systemic lupus erythematosus.

We have explored the relationship between possible hemostatic changes and clinical manifestation of the systemic lupus erythematosus (SLE) as a function of greater or lesser disease activity according to Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K) criteria. Endothelial injury and hypercoagulability were investigated in patients with SLE by measuring thrombomodulin (TM), D-dimer (DDi) and thrombin generation (TG) potential. A total of 90 participants were distributed into three groups: 1) women with SLE presenting with low disease activity (laSLE) (SLEDAI-2K ≤ 4), 2) women with SLE presenting with moderate to high disease activity (mhaSLE) (SLEDAI-2K > 4), and 3) a control group comprising healthy women.

Evaluation of potential biomarkers for the diagnosis and monitoring of Systemic Lupus Erythematosus using the Cytometric Beads Array (CBA).

Background: Systemic Lupus Erythematosus (SLE) is an autoimmune, multisystemic disease. Currently diagnosis depends on complex criteria developed by the American College of Rheumatology. Moreover, the lack of specific biomarkers also challenges the diagnosis.

Hemostatic Abnormalities in Dementia: A Systematic Review and Meta-Analysis.

Alzheimer's disease (AD) is considered the most frequent cause of dementia. It is known that vascular risk factors play an important role in the development and progression of this condition. Alterations in vascular walls represent documented findings in patients with AD and other dementias affecting elderly people.

Objective: This study has investigated whether high levels of Reticulocytes-C4d (R-C4d) and Platelets-C4d (P-C4d) reflecting recent activity in SLE patients are correlated with changes in natural anticoagulation components, coagulation activation and endothelial injury markers.

Methods: This study included three groups: 1) healthy women (control, n = 30); 2) women with low activity of the disease (SLEDAI 2 K ≤ 4, n = 30); 3) women with active disease (moderate or high activity) (SLEDAI 2 K > 4, n = 30). Median fluorescence intensity (MFI) of R-C4d and P-C4d were determined by flow cytometry using double labeling with specific monoclonal antibodies.

Systemic lupus erythematosus: disease activity may influence the release of endothelial microparticles?

: To evaluate blood-borne endothelial microparticles (EMPs) in women with SLE and correlated these to disease activity as defined by the SLEDAI-2K score. The study takes cross-sectional design. A total of 90 age-matched women were recruited including: G1 (healthy volunteers, n = 30), G2 (women with SLE and low disease activity (SLEDAI-2K score ≤4; n = 30) and G3 (women with SLE and moderate/high disease activity (SLEDAI-2K score >4; n = 30).
