The delta neutrophil index (DNI) is a new inflammatory marker that measures the proportion of circulating immature granulocytes.[13,14] Because infectious conditions are associated with increased immature granulocyte levels, several investigators have examined whether this level can be used to predict the development of sepsis.[15,16] On the other hand, the serum myeloperoxidase index (MPXI) is a new index of the level of serum myeloperoxidase (MPO), which is a newly observed inflammatory marker. Here, MPO is linked to Sepsis.
