Expression of platelet microparticles in patients with diabetic nephropathy and its relationship with renal damage
Journal Title: Chinese Journal of Blood Transfusion - Year 2024, Vol 37, Issue 7
Abstract
Objective To investigate the expression levels of platelet microparticles(PMPs) in patients with diabetic nephropathy (DN) and their relationship with renal injury. Methods Thirty DN patients, 30 T2DM patients without DN and 30 healthy controls were enrolled. Flow cytometry was used to detect the quantity and phenotype of PMPs, and ELISA was used to measure the levels of plasma renin, angiotensin Ⅱ (angiotoninⅡ, AngⅡ), vascular endothelial growth factor (vascular endothelial growth factor, VEGF) and transforming growth factor-β1(transforming growth factor-β1, TGF-β1). Kidney function was determined by blood biochemistry. Results The quantity of PMPs in the DN group was (1 564±346) particles/μL, which was significantly higher than that in the non-DN group (1 246±312) particles/μL and the control group (1 223±299) particles/μL (P<0.05). The PMPs in the DN group mainly expressed CD62P and CD41a, accounting for (76.5±12.3)%. Moreover, the levels and activation of PMPs increased with the progression of DN. The quantity of PMPs was positively correlated with renin and other factors (r=0.56-0.62, P<0.05), negatively correlated with the glomerular filtration rate (GFR) (r=-0.64, P<0.05), and positively correlated with the urinary albumin excretion rate (UAE) (r=0.66, P<0.05). PMPs were also an independent influencing factor of UAE (β=12.34, P<0.05). Conclusion PMPs expression is elevated in DN patients, which may be associated with renal injury, but it is insufficient to confirm its role in the pathogenesis of DN.
