HAMP and Alzheimer disease: Table 2 presents the results as median±SD with associated P. While hepcidin, serum iron, TIBC, and % saturation did tend to be higher in AD patients compared to controls, only serum ferritin reached statistical significance with the median slightly more than 1.5x as high (P = 0.004). Males had a median more than 2x as high as controls (P = 0.05) but the difference in females was not significant for medians, and both AD and control females were lower than males. Furthermore, serum Aβ40 and Aβ42 levels as well as the Aβ40/42 ratio exhibited no significant trends.
