摘要

Objectives

We studied several acute inflammatory materials (AIM) such as various inflammatory cytokines, oxidative stress, and heat shock proteins in ARDS patients by simultaneously measuring from bronchoalveolar lavage fluid (BALF) and plasma.

Design and methods

AIM were measured by using plasma and BALF sampling obtained from ARDS group (n = 12) and non-ARDS group (n = 12).

Results

In the BALF, only HSP 47 was significantly increased in ARDS group than non-ARDS group. In plasma, GRP 94, HSP 90, HSP 60, HSP 47, GPx-3, and IL-8 were increased significantly in ARDS group. In short, most of the AIM in BALF or plasma were not significantly different in ARDS group as compared with non-ARDS group. Ninety-day mortality was significantly related to HSP90, HSP 60 and GPx-3 in plasma but not in BALF.

Conclusion

Alteration of AIM levels in both BALF or plasma of ARDS group was not remarkable compared with the non-ARDS group. Our result suggests the need to reconsider ARDS pathophysiology and therapeutic strategy.
