Previous studies have indicated that plasma β-TG and PF4 levels are significantly higher in patients with chronic renal failure than in healthy individuals, and their elevated levels are negatively correlated with blood urea nitrogen, creatinine, and creatinine clearance [196,197]; however, in patients with DKD, urinary β-TG levels are considerably higher than in healthy controls. Here, PF4 is linked to diabetic kidney disease.
