The admission mean value of serum IL-8 is statistically significantly elevated in sepsis group which was 419.22 pg/mL with a range of (190–850 pg/mL) when compared to mean value in SIRS group which was 181.44 pg/mL with a range of (110–310 pg/mL) (P < 0.001) (Table 2). This evidence concerns the gene CXCL8 and systemic inflammatory response syndrome.
