Neutrophil-to-Albumin Ratio as A Novel Predictor of Mortality in Patients with Sepsis

Sepsis is a syndrome involving physiological, pathological, and biochemical abnormalities caused by infection. Very few studies have been performed to evaluate the prognostic value of the neutrophil-to-albumin ratio. The present study aimed to evaluate the neutrophil-to-albumin ratio in patients with sepsis admitted to the intensive care unit (ICU).

All patients admitted to the ICU with a diagnosis of sepsis were included in the study. The inclusion criteria entailed the age range of ≥18 years, having sepsis, and hospitalization in the ICU for more than two weeks.

A total of 75 patients with a mean age of 72.34 years were evaluated, and 57.8% of cases died. There was a significant difference between neutrophils on the second and third days between deceased and discharged patients. The neutrophil-to-albumin ratio at the time of admission, the second day, and the third day were 31.62, 33.36, and 34.31, respectively; nonetheless, no significant difference was observed between the deceased and discharged (P>0.05).

As evidenced by the results of this study, the neutrophil-to-albumin ratio in deceased patients was higher than that in discharged ones; however, this difference was not statistically significant. Moreover, neutrophil percentage, duration of mechanical ventilation, and duration of hospitalization in deceased patients were significantly higher, as compared to those in discharged patients.
