MMP-9 Concentration in Peritoneal Fluid Is a Valuable Biomarker Associated with Endotoxemia in Equine Colic

Table 6

IL-1β and TNF-α concentrations in plasma and peritoneal fluid in the groups negative (, ≤6/19 points), questionable (, 7-9/19 points), or positive (, ≥10/19 points) for sepsis. Median (lower quantile–upper quantile). No significant differences.

Parameter	Negative	Questionable	Positive
IL-1β (pg/ml) in plasma	2.26 (2.20–2.50)	2.20 (1.60–2.20)	2.29 (2.20–2.34)
IL-1β (pg/ml) in peritoneal fluid	2.40 (2.23–2.68)	2.45 (1.68–2.57)	2.59 (2.42–2.95)
TNF-α (pg/ml) in plasma	7.9 (7.9–13.0)	7.9 (6.7-7.9)	8.9 (7.9–32.3)
TNF-α (pg/ml) in peritoneal fluid	7.9 (7.9–8.1)	7.9 (6.7–10.5)	22.1 (7.9–34.2)
