Coagulation directly contributes to the systemic inflammation that characterizes severe sepsis [ 15, 16, 17, 18, 19, 20, 21, 22, 23].
However, an exaggerated response can lead to a situation in which coagulation itself contributes to its most severe form of the disease causing microvascular thrombosis, organ dysfunction and bleeding [ 16].
The protease-activated receptor 1-mediated enhancement of Itgb6-dependent TGF-beta activation has been proposed to represent one mechanism by which activation of the coagulation cascade contributes to the development of acute lung injury [ 39].
Various authors have demonstrated a significant correlation between the incidence of thromboembolic events and a worse prognosis of neoplastic disease, supporting the idea that the activation of the blood coagulation system contributes to tumour aggressiveness and vice versa.
In contrast, inhibitors of the TF-initiation complex reduce proinflammatory cytokines such as interleukin-6 in lethal sepsis models induced by high-dose endotoxin [ 26, 27], indicating that signaling by coagulation proteases contributes only to exacerbated cytokine production, and not to the initial inflammatory response.
It is known that glomerular thrombosis and vascular thrombosis due to the activation of inflammation and coagulation pathway contribute to the occurrence of acute renal failure in sepsis [5, 29].
It has been reported that many increased or decreased coagulation factors contribute to cancer growth, progression and metastasis [ 16].
Glomerular and microvascular thrombosis due to the activation of the inflammation and coagulation pathway contribute to the occurrence of acute renal failure in sepsis.
Nephropathy, which has been associated to immune-mediated mechanims, is characterized by presence of membranoproliferative glomerulonephritis and tubulointerstitial nephritis (rarely amyloidosis) [ 31] that can enable the loss of antithrombin III, a potent inhibitor of serine proteases in the coagulation cascate, contributing to the development of DIC.
