BACKGROUND: We investigated whether a decrease in the serum zinc level (SZL) among patients with sepsis admitted to the intensive care unit (ICU) was related to sepsis-induced coagulopathy.

METHODS: All patients (≥20 years) with a diagnosis of sepsis defined by Sepsis-3 criteria, presenting to the ICU between June 2016 and July 2017, were enrolled. Demographic characteristics and the Sequential Organ Failure Assessment (SOFA) and Japanese Association of Acute Medicine (JAAM) disseminated intravascular coagulation (DIC) scores were recorded. Blood samples were collected upon admission and analyzed for SZL.

RESULTS: One hundred patients with sepsis (median age, 70 years) were enrolled. Patients with SOFA scores ≥8 had a significantly lower SZL compared to those with SOFA scores <8 (p < 0.001). The SZL in the DIC group (JAAM DIC score ≥4) was significantly lower than that in the non-DIC group (JAAM DIC score <4) (p < 0.001). Analysis of receiver operating characteristic (ROC) curves for prediction of sepsis-induced DIC based on SZL in patients with sepsis showed a cut-off value of 25 µg/dL for zinc level and a sensitivity of 63% and a specificity of 72% with AUC of 0.7 (p = 0.0065).

CONCLUSION: We observed that SZL reflects organ failure, particularly coagulopathy, in patients with sepsis.
