On a final note, baseline levels of HEP-25 levels associated inversely with S-calcitriol and HB (by a trend for significance; p = 0, 06 for both), and positively with S-ferritin, TSAT and CRP levels; associations of which all have been demonstred previously in a context of CKD [9, 19, 25]. The gene discussed is CRP; the disease is chronic kidney disease.
