Abstract

PurposeThis pilot study was aimed to establish techniques for assessing and observing trends in endothelial function, antioxidant status and vascular compliance in newly diagnosed HFE haemochromatosis during the first year of venesection.Patients/methodsUntreated newly diagnosed HFE haemochromatosis patients were tested for baseline liver function, iron indices, lipid profile, markers of endothelial function, anti-oxidant status and vascular compliance. Following baseline assessment, subjects attended at 6-weeks and at 3, 6, 9 and 12-months for follow-up studies.ResultsTen patients were recruited (M = 8, F = 2, mean age = 51 years). Venesection significantly increased high density lipoproteins at 12-months (1.25 mmol/L vs. 1.37 mmol/L, p = 0.01). However, venesection did not significantly affect lipid hydroperoxides, intracellular and vascular cell adhesion molecules or high sensitivity C-reactive protein (0.57 μmol/L vs. 0.51 μmol/L, p = 0.45, 427.4 ng/ml vs. 307.22 ng/ml, p = 0.54, 517.70 ng/ml vs. 377.50 ng/ml, p = 0.51 and 290.75 μg/dL vs. 224.26 μg/dL, p = 0.25). There was also no significant effect of venesection on anti-oxidant status or pulse wave velocity (9.65 m/s vs. 8.74 m/s, p = 0.34).ConclusionsVenesection significantly reduced high density lipoproteins but was not associated with significant changes in endothelial function, anti-oxidant status or vascular compliance. Larger studies using this established methodology are required to clarify this relationship further.
