Abstract Objective To evaluate the value of serum pancreatic stone protein (PSP) for the early diagnosis of early-onset neonatal sepsis (EONS). Methods Ninety neonatal with infectious risk factors or infectious symptoms admitted to the Huai′an Maternity and Child Healthcare Hospital Affiliated to Yangzhou University Medical Academy within 24 h after birth from January to June 2014 were enrolled. They were divided into sepsis group (33 cases) and non-sepsis group (57 cases) depending on whether the diagnostic standard of early-onset neonatal sepsis was met. Twenty neonatal with good general situations admited at the same time without infection poisoning manifestation were treated as the control group. The blood samples were obtained from children on 1, 3 and 7 d after birth. The levels of serum PSP and IL-6 were measured, and the data was statistical analyzed. Results There were statistically significant among three groups at all time points (all P < 0.01), and the levels of serum PSP on 1, 3 and 7 d after birth in sepsis group were all higher than those of the non-sepsis group, the differences were statistically significant (all P < 0.05). Levels of serum PSP showed upward trend during d1-d3 after birth, and downward trend during d3-d7. Area under the curve (AUC) of ROC of PSP at 1 d after birth in the diagnosis of sepsis was 0.802 [95%CI: 0.70-0.90, P < 0.01], 3 d after birth was 0.836 (95%CI 0.74-0.93, P < 0.01), the AUC of the combination of PSP and IL-6 in the diagnosis of sepsis at 1 d after birth was 0.879 (95%CI: 0.80-0.95, P < 0.01). Conclusion The level of serum PSP of neonatal has certain clinical value in early diagnosis of EONS. Combination detection of serum PSP and IL-6 in the diagnosis of sepsis at 1 d after birth can improve the sensibility to diagnose early-onset neonatal sepsis and reduce the rate of missed diagnosis.
