Background: To assess any correlation of plasma hepatocyte growth factor (HGF) levels with relevant endothelial cell injury parameters and determine the prognostic value in septic patients. Methods: A prospective, observational study was conducted in patients with sepsis admitted to the Department of Critical Care Medicine at the Zhongda Hospital from November 2017 to March 2018. Plasma HGF levels were measured by enzyme-linked immunosorbent assay in the first 24 h after admission (day 1) and on day 3. The primary endpoint was defined as all-cause 28-day mortality. Furthermore, we analyzed the correlation of HGF with relevant endothelial cell injury markers. Results: Eighty-six patients admitted with sepsis were included. HGF levels of nonsurvivors were elevated compared to those of survivors on day 1 (1940.62 ± 74.66 pg/mL vs. 1635.61 ± 47.49 pg/mL; P = 0.002) and day 3 (1824.82 ± 137.52 pg/mL vs. 1309.77 ± 83.49 pg/mL; P = 0.001) and showed a strong correlation with von Willebrand factor (r = 0.45, P < 0.0001), lactate (r = 0.35, P = 0.0011), pulmonary vascular permeability index (r = 0.38, P = 0.0241), first 24 h fluid administration (r = 0.38, P < 0.0001), and sequential organ failure assessment score (r = 0.40, P = 0.0001). Plasma HGF levels were able to prognostically discriminate between survivors and nonsurvivors on day 1 (AUC: 0.72, 95%CI: 0.60-0.84) and day 3 (AUC: 0.77, 95%CI: 0.63-0.91). Conclusions: HGF levels are associated with sepsis and correlated with established markers of endothelial cell injury. Elevated HGF levels in sepsis patients are an efficient indicator of poor prognosis. Trial registration: The study was registered in Clinical Trial (Registration Number: NCT02883231).

Abstract Direct interaction of unactivated primary monocytes with endothelial cells induces a mitogenic effect in subconfluent, injured endothelial monolayers through activation of endothelial Met. We now report that monocytes' contact-dependent mitogenicity is controlled by activation-mediated regulation of hepatocyte growth factor. Direct interaction of unactivated monocytes with subconfluent endothelial cells for 12 hours resulted in 9- and 120-fold increase in monocyte tumor necrosis factor-α (TNFα) and interleukin-1β (IL-1β) mRNA levels and bitemporal spike in hepatocyte growth factor that closely correlates with endothelial Met and extracellular signal-related kinase (ERK) phosphorylation. Once activated, monocytes cannot induce a second wave of endothelial cell proliferation and endothelial Met phosphorylation and soluble hepatocyte growth factor levels fall off. Monocyte-induced proliferation is dose dependent and limited to the induction of a single cell cycle. Monocytes retain their ability to activate other endothelial cells for up to 8 hours after initial interaction, after which they are committed to the specific cell. There is therefore a profoundly sophisticated mode of vascular repair. Confluent endothelial cells ensure vascular quiescence, whereas subconfluence promotes vessel activation. Simultaneously, circulating monocytes stimulate endothelial cell proliferation, but lose this potential once activated. Such a system provides for the fine balance that can restore vascular and endothelial homeostasis with minimal overcompensation.
