Plasma MMP-9 and TIMP-1 levels on ICU admission are associated with 30-day survival.

Background: Matrix metalloproteinases (MMPs) are involved in systemic inflammatory responses and organ failure. The aim of this study was to evaluate early circulating plasma levels of MMP‑2, MMP‑9 and their inhibitors TIMP‑1 and TIMP‑2 and their prognostic significance in critically ill patients on admission to the intensive care unit (ICU).

Methods: In a single center prospective study 120 consecutive patients (72.
