HAMP and hereditary hemorrhagic telangiectasia: [63] In the HHT cohort, there was a wide range of hepcidin:ferritin ratios (Table 2). Importantly, the geometric mean and 95% confidence intervals (0.49 [95% confidence intervals 0.35, 0.62]) corresponded to the hepcidin:ferritin ratio values reported for the control group studied by Piperno et al. [63] Since the relationships between ferritin and hepcidin in the HHT patients were very similar to those reported for general population controls, [58], [63] we concluded there was no evidence to suggest a generalised abnormality of iron handling in the HHT cohort.
