Background:
Early identification and diagnosis of sepsis are very important because timely and appropriate treatment can improve the survival outcomes.
Aim:
The aim of this study was to explore the clinical significance of serum cystatin C level in sepsis.
Materials And Methods:
The levels of serum cystatin C, C-reactive protein (CRP), and procalcitonin (PCT) were measured via enzyme-linked immunosorbent assay (ELISA). The patients with sepsis were followed up for 30 days to record their survival conditions.
Results:
The expression level of cystatin C was remarkably elevated in patients with sepsis compared with that in healthy controls. The serum cystatin C level was significantly correlated with the SOFA score and CRP, PCT, and creatinine levels in patients with sepsis. The patients in death group had a markedly higher level of serum cystatin C than those in survival group. The area under curve (AUC) of cystatin C for assessing the 30-day mortality rate of sepsis patients was 0.765.
Conclusion:
The serum cystatin C level is elevated in patients with sepsis and it may serve as a biomarker for early diagnosis of sepsis and possess promising effects in assessing the severity of sepsis and the prognosis of patients.
