Objective To investigate the clinical signification of plasma interleukin-17 (IL-17) 1evel in patients with acute respiratory distress syndrome (ARDS).Methods Forty-five adult ARDS patients and 22 healthy controls were enrolled in this study. The plasma cytokine levels of IL-17, IL-6 and IL-10 were measured by enzyme linked immunosorbent assay. Meanwhile, the baseline data of demographic and clinical tests including oxygenation index, procalcitonin and brain natriuretic peprtide were collected, the acute physiological and chronic health Ⅱ (APACHEⅡ) score and sequential organ failure assessment (SOFA) score were recorded. The main outcome was defined as hospital mortality within 28-day follow-up.Results The plasma concentration of IL-17, IL-6 were higher in the ARDS patients (P<0.05) compared with the controls and the mean levels of IL-17, IL-6 and the APACHEⅡ score and the SOFA score in the non-survivors was higher than those in the survivors (P<0.05). In particular, there was a significant correlation between the plasma levels of IL-17 and IL-6 (P<0.05). Logistic regression and COX multivariate survival analysis suggested that age and SOFA score may be prognostic factors for ARDS.Conclusions The plasma concentration of IL-17 is significantly increased in ARDS patients, and its expression is linearly related to the proinflammatory factor IL-6. Both are important inflammatory markers in the acute phase of ARDS and may be important disease severity and prognostic indicators in addition to age and SOFA score.
