Protein carbonyl content (PCC) measurements of ITP patients and controls. PCC measurements were performed in patients with acute ITP (Acute ITP, n=7), chronic ITP (Chronic ITP, n=10), and pediatric controls (n=15). PCC levels are significantly higher in all ITP patients (All ITP= Acute ITP + Chronic ITP, p=0.0052) compared to controls. Furthermore, PCC levels are significantly higher in patients with chronic ITP compared to controls (p=0.0424), as well as in patients with acute ITP compared to controls (p=0.0261).
