Clinical Trial Summary

-Describe platelet activity in type 2 diabetes as a participant in vascular inflammation. -Compare platelet activity in patients with type 2 diabetes mellitus versus healthy controls. -Study and describe platelet activity in patients with type 2 diabetes mellitus in association with ischemic cardiovascular disease in relation to duration of diabetes mellitus .


Description:

Type2diabetes mellitus(T2DM)is most prevalent and costly chronic disease(Leon et al 2015).according to IDF a further increase to 642million diagnosed individual by2040(Ogurtsova et al 2017).the major cause of morbidity and mortality in DM is macrovascular complications.75% of diabetic patients die of cardiovascular disease(CVD)( Ridker et al2017).Platelets are one of blood cells 1,5-3um in size and survive 8-10days ,their function extended beyond homestasis and thrombosis to be an active participant in intiating and sustaining vascular inflammation as well as in prothrombotic complications of CVD(Festa et al2002).platelets are hyperactive in diabetic patients ,the coagulation cascade is dysfunctional ,platelet inT2DM adhere to vascular endothelium and aggregate more readily than those in healthy people(Pretorius2011)*.platelets are activated when they are in contact with damaged vascular endothelium , once activated they secrete awide spectrum of inflammatory mediators , once they are activated , they intiate reactions by changes in the level of expression of surface glycoproteins(GP)results , which act as receptors for platelet agonist and for adhesive proteins involved in platelet aggregation(Pretorius etal2015)**.platelet activity can be measured by flow cytometry ,as flow cytometry allows the simultaneous detection of surface antigens in a sensitive and specific manner , it is therefore possible to examine aspects of the platelet membrane activity . the available platelet markers areCD41a marker forGP2b ,CD42 a marker for GP1b.both are used for platelet identification.( Pretorius et al 2017)***.CD62 a marker for P-selectin ,anti-CD62 react with alpha granule membrane protein which is expressed on the surface of activated platelet.CD63 a marker for GP4 and anti-CD63 react with lysosomal granule-membrane glycoprotein that is expressed on surface of activated platelet. CD62andCD63 are markers of platelet activation (Ibrahim et al 2017).knowing the major role of platelets in inflammatory and healing process in the vascular system especially in diabetic patients ,created the urgency to study the impact of platelet activity in diabetic patients whom has macrovascular risk using flowcytometry.
