“…This decrease correlated with higher disease severity as measured by higher levels of PCT Brought to you by | Universitaetsbibliothek Basel Authenticated Download Date | 10/9/17 4:17 PM and CRP, and higher risk scores (qSOFA and PSI). These results are in line with previous research [26][27][28]. The physiopathological mechanism of decreasing TRP during infection and inflammation is a matter of current discussion [29].…”

“…In a mouse model, IDO inhibitors potentiated cancer chemotherapy because of an immune-modulating effect of IDO [32]. Also, a blockade of IDO showed a reduction in mortality from peritonitis and sepsis in mice [27]. Despite these promising early results, clinical data is currently lacking demonstrating whether an IDO inhibitor could improve patient outcome in acute infection and sepsis.…”

“…Clinical and experimental animal studies highlight an important role for IDO1 and the Kyn pathway in response to endotoxic shock. IDO1 expression and activity are increased in septic patients and animals in inflamed cardiac tissue, spleen DCs, bone marrow-derived CD11b + cells and endothelial cells of resistance vessels [125,182,479,480]. Moreover, IDO1 activity measured as the plasma Kyn/L-Trp ratio is significantly elevated in patients with bacteraemia caused by S. aureus, S. pneumoniae, E. coli and β-haemolytic streptococci, with the extent of increase representing an independent predictor of disease severity and death [481,482].…”

“…A more recent study reported that IDO1 gene deficiency or 1-D-MT treatment also afforded host protection and reduced mortality in mouse models of bacterial peritonitis or sepsis after caecal ligation and puncture, involving elevated chemokine expression and enhanced recruitment of neutrophils and mononuclear cells into the peritoneum, which correlated with reduced bacterial load [480]. The septic phenotype apparent in wild-type mice was also recapitulated in IDO1 −/− mice treated with Kyn or reconstituted with IDO1 +/+ bone marrow cells, suggesting that Kyn produced by IDO1-expressing leucocytes plays an important role in promoting sepsis [480]. These studies identify a deleterious proinflammatory action for IDO1 during sepsis.…”
