Comparison of indicators of iron status in male patients with dEPP and male first-time blood donors

Serum iron indicesEPP patients, n = 67First-time blood donors, n = 611
sFe, μM15.1 ± 6.6*16.7 ± 6.0
TIBC, μM63.0 ± 6.954.5 ± 10.0
TS, %23.9 ± 10.331.1 ± 10.9
sFn, μg/L37 (10-119)101 (35-220)
  • Values are means plus or minus SD, except for sFn, which are medians and 95% ranges. EPP patients are males aged 16 to 77 years who have never been prescribed iron supplements. Blood donors are male first-time donors aged 17 to 62 years from South Wales15; samples for analysis were obtained prior to first donation. Only TIBC showed any correlation with sFn (rs = −0.412, P < .001).

  • * P value is not significant.

  • P < .001 compared with donors.
