ABSTRACT
BACKGROUND AND PURPOSE:
The aim was to investigate the plasma levels of hemostasis components in multiple sclerosis (MS) and their association with clinical and magnetic resonance imaging (MRI) outcomes.METHODS:
In all, 138 MS patients [85 with relapsing-remitting MS (RR-MS) and 53 with progressive MS (P-MS) with a mean age of 54 years; 72.5% female; median Expanded Disability Status Scale 3.5; mean disease duration 21 years] and 42 age- and sex-matched healthy individuals (HI) were studied. All subjects were examined with 3 T MRI and clinical examinations. Plasma levels of hemostasis factors [procoagulant, factor XII (FXII)] and inhibitors [tissue factor pathway inhibitor (TFPI), thrombomodulin, heparin cofactor II, a disintegrin-like and metalloprotease with thrombospondin type 1 motif 13 (ADAMTS13) and plasminogen activator inhibitor 1 (PAI-1)] were evaluated by magnetic Luminex assays and enzyme-linked immunosorbent assay. Associations between hemostasis plasma levels and clinical and MRI outcomes were assessed.RESULTS:
Lower ADAMTS13 levels were found in MS patients compared to HI (P = 0.008) and in MS patients presenting with cerebral microbleeds compared to those without (P = 0.034). Higher PAI-1 levels were found in MS patients compared to HI (P = 0.02). TFPI levels were higher in the P-MS subgroup compared to RR-MS patients (P = 0.011) and compared to HI (P = 0.002). No significant associations between hemostasis plasma levels and clinical or MRI outcomes were found.CONCLUSIONS:
Decreased ADAMTS13, particularly in MS patients with cerebral microbleeds, which deserves further investigation, and increased PAI-1 and TFPI levels were observed in MS patients, which deserves further investigation. No relationship between hemostasis plasma levels and measures of disease severity was detected.Palavras-chave
