HAMP and Sepsis: In contrast with hepcidin, for each increase of 1 ng/mL of HBP upon admission the corresponding difference in peak serum creatinine level (defined as B), was significantly associated with peak creatinine values in the sepsis group, B = 0.190 μmol/L (CI 0.056–0.325, p = 0.006), whereas no significant correlation was observed between peak creatinine values and HBP levels in the non-sepsis group, B = 0.486 μmol/L (CI -0.452–1.423, p = 0.303).
