Abstract
BACKGROUND AND OBJECTIVE: There are limited data regarding serum activin-A as a biomarker for sepsis. We examined whether serum activin-A concentration could predict sepsis severity and prognosis in the management of critically ill patients with sepsis.
METHODS: The subjects were adult patients suspected of having sepsis and admitted to intensive care unit (ICU) from January 2013 to March 2014. Serum activin-A concentration was measured in blood sampled within 48 h after ICU admission. The primary and secondary outcomes were the diagnostic value of serum activin-A concentration as a biomarker of sepsis and the prognostic value for predicting the clinical outcomes of sepsis, respectively.
RESULTS: One hundred and thirty patients who had clinically suspected sepsis were included. Most (66.2%) were male; their median age was 65 years, and their Acute Physiology and Chronic Health Evaluation II score was 22.3. Serum activin-A concentration tended to increase with sepsis severity and differed significantly between those with non-sepsis and severe sepsis and between those with severe sepsis and septic shock. The risks of sepsis, severe sepsis and septic shock were significantly higher in patients with a serum activin-A concentration of 251, 319 and 432 pg/mL or greater, respectively. Serum activin-A concentration was significantly associated with the Acute Physiology and Chronic Health Evaluation II score, Sequential Organ Failure Assessment score, Charlson comorbidity index and ICU mortality.
CONCLUSION: Serum activin-A was a predictor of sepsis severity and a prognostic marker in critically ill patients with sepsis. Serum activin-A concentration in the early phase of sepsis was associated with prognostic indexes on ICU admission and with ICU mortality.
