NCT02649660

Brief Summary

This study aims to evaluate whether platelets are biochemically and functionally altered in Fabry disease (FD) and therefore possibly implicated in FD manifestations such as cerebrovascular events. To test this hypothesis the investigators aim to compare platelet and plasma lipid profiles, as well as platelet function and coagulation parameters of FD patients and healthy controls.

Outcome Measures

Primary Outcomes (2)

  • Differences in sphingolipid profiles of platelets and plasma between Fabry disease patients and healthy subjects

    Determination of sphingolipid concentrations in isolated platelets and plasma by targeted LC-MS (liquid chromatography mass spectrometry)-based lipidomics analysis of globotriaosylceramides (Gb3), globotriaosylspingosines (Lyso-Gb3), globotetraosylceramides (Gb4), lactosylceramides (LacCer), glucosylceramides, ceramides, sphingomyelins, sphingosines and sphingosine-1-phosphates.

    Baseline

  • Differences in platelet function assessed by aggregometry

    Determination of platelet aggregation after agonist stimulation with TRAP (thrombin receptor activator peptide), ADP (adenosine disphosphate) and arachidonic acid by light transmission aggregometry.

    Baseline

Secondary Outcomes (7)

  • Differences in expression of the platelet activation marker P-selectin (CD62P) between Fabry disease patients and healthy subjects at baseline and after agonist stimulation

    Baseline

  • Differences in expression of the platelet activation marker CD63 between Fabry disease patients and healthy subjects at baseline and after agonist stimulation

    Baseline

  • Differences in plasma levels of the platelet activation marker soluble P-selectin between Fabry disease patients and healthy subjects

    Baseline

  • Differences in plasma levels of the platelet activation marker sCD40L between Fabry disease patients and healthy subjects

    Baseline

  • Differences in presence of platelet aggregates between Fabry disease patients and healthy subjects

    Baseline

  • +2 more secondary outcomes
