Abstract:
Intestinal barrier dysfunction would lead to a rigorous inflammatory reaction due to the translocation of intestinal lumen-derived bacteria and endotoxins. The aim of the present study was to investigate whether intestinal barrier dysfunction occurs in patients with acute Stanford type A aortic dissection (ATAAD) and to determine its potential relationship with the plasma levels of several inflammatory biomarkers in the progression of ATAAD. Design and Methods: Serum samples from a total of 46 patients with ATAAD and 36 healthy volunteers were prospectively collected and analyzed. The serum levels of diamine oxidase (DAO), lactate dehydrogenase (LDH), interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), and C-reactive protein (CRP) were measured using colorimetric assay, enzyme-linked immunosorbent assay, and immunoturbidimetric assay. Results: Serum levels of DAO, LDH, IL-6, TNF-α, and CRP in patients with ATAAD were significantly higher than those in healthy participants. A significantly positive correlation between DAO activity and IL-6 ( r = .56, P 〈 .001), TNF-α ( r = .63, P 〈 .001), and CRP ( r = .53, P 〈 .001) was observed. Moreover, the activity of DAO correlated negatively with the Pao 2 /fraction of inspired oxygen (Fio 2 ) ratio ( r = −.39, P = .007). Conclusions: Intestinal barrier dysfunction, reflected by an increased level of serum DAO, may play an important role in the development of systemic inflammatory responses in patients with ATAAD. Therefore, strategies of preserving a normal intestinal barrier function may open new horizons in the treatment of inflammation-related adverse events in the setting of ATAAD.
