When analysing the possible impact of iron on pentosidine in HD patients who had the highest exposure to iron, plasma pentosidine levels did not differ significantly (p = 0.87) between those who received versus those who did not receive iron therapy: median 53.8 (18.5–85.6) versus median 50.2 (25.0–85.0) nmol/g albumin. Here, ALB is linked to Huntington disease.
