Polymorphisms of IL-1beta/-1470, IL-1beta/-511, IL-1beta/-31, IL-4/-589, IL-6/-572, IL-8/-251, IL-10/-819, and TNFalpha/-308 are susceptibility loci for the development of sepsis and organ dysfunction in major trauma patients.
We investigate whether interleukin-10 (IL-10)-1082 G/G genotype is associated with the mortality rate of acute respiratory distress syndrome (ARDS) in a hospital-based case-control study in China conducted on 314 patients with ARDS and 210 controls admitted to an intensive care unit for sepsis, trauma, aspiration, or massive transfusions.
We sought to determine whether there was an association between IL-6, IL-10 and IL-17 polymorphisms with cytokine production and development of sepsis.
This study confirms that an active response against pediatric sepsis involves the expression of HMOX1 and IL10, suggesting that the high antioxidant status associated with HMOX1 short-allele septic carriers might provide a beneficial environment for sepsis resolution.
In conclusion, the increased ILT4 expression and IL-10 production and the decreased CD86 expression and IL-12 production indicate that during sepsis monocytes undergo substantial modulation of the surface and cytokine phenotype.
In response to pathogen infection, pro-inflammatory cytokines [interleukin-6 (IL-6), IL-8, IL-18 and tumor necrosis factor-α (TNF-α)] and anti-inflammatory cytokine (IL-10) increased in patients with sepsis.
Blockade of IL-10R by Ab or genetic deficiency of IL-10 resulted in 3-5-fold higher concentrations of IL-27(p28) in endotoxic shock and polymicrobial sepsis.
This work attempts to further quantitatively assess the association of three widely evaluated polymorphisms of IL-10 (-592C/A, -819C/T, -1082A/G) with sepsis susceptibility through a meta-analysis.
Patients with IL-10 (-1082A/A) genotypes were found significantly higher in post traumatic sepsis patients and had a significantly higher risk to developed sepsis complication (p < 0.05, OR = 0.86, C.I = 0.08-8.8).In case of TNF-α (-308) position, GA and GG genotype patients have a significantly lower risk of poor outcome (p < 0.05, OR = 0.25, C.I = 0.01-1.3) and (p < 0.05, OR = 0.22, C.I = 0.01-0.5) in comparison to AA genotype.
In this study, the Th1, Th2, Treg transcription factors, and related cytokines IFN-γ, IL-4, and IL-10 levels of sepsis and severe sepsis patients in peripheral blood were significantly higher than those of the normal controls.
We found an association between the SNP LTA +252 with the development of sepsis [OR 1.29 (1.00-1.68)]; the SNP IL10 -1082 with sepsis severity [OR 0.53 (0.29-0.97)]; the TNF -308 with mortality [OR 0.33 (0.12-0.95)]; and the IL10 -592 and IL10 -1082 with admission to the intensive care unit (ICU) [OR 3.36 (1.57-7.18)] and [OR 0.18 (0.04-0.86)], respectively.
This suggests that interleukins such as IL-6 and IL-10 have a close association with coagulopathy and fibrinolytic dysregulation in sepsis and can be considered as candidates for potential therapeutic targets in SAC.
We detected higher serum levels of cytokines TNF-α (5.7 vs. 0.7 pg/ml, P < 0.001), IL-6 (24.8 vs. 3.8 pg/ml, P < 0.001), IL-10 (30.0 vs. 11.9 pg/ml, P = 0.040), and VEGF (177.9 vs. 48.1 pg/ml, P = 0.018) in sepsis sera.
Cytokine levels were higher in patients with sepsis vs. controls (interleukin [IL]-10, blisters: 65.9 vs. 4.3 pg/ml, P < 0.001, serum: 25.7 vs. 4.5 pg/ml, P = 0.004; IL-6, blisters: 41.9 vs. 0.03 pg/ml, P < 0.001, serum: 45.5 vs. 2.1 pg/ml, P < 0.001).
These results demonstrate that monocyte derived IL-10 acts to inhibit potentially protective cell mediated immune responses against B. pseudomallei, but may also moderate the pathological effects of excessive cytokine production during sepsis.
After adjustment for shock and sepsis status at admission, CD74 and IL10 levels were found to be significantly associated with IAI occurrence [subdistribution hazard ratio (95% confidence interval) 0.67 (0.46-0.97) for CD74 D3/D1 expression ratio and 2.21 (1.63-3.00) for IL10 at D3].
We assessed inflammatory (im)balance by measuring pro-inflammatory interleukin-6 and anti-inflammatory interleukin-10 during three distinct time periods after sepsis, and assessed its association with mortality.
Moreover, we identified a novel intracellular signaling molecule, cAMP-response element binding protein (CREB), which serves as a pivotal transcription factor for upregulating IL-10 production by B-1a cells in sepsis through its nuclear translocation and binding to putative responsive elements on IL-10 promoter.
We investigated the effects of 24 h delayed normobaric oxygen (NBO<sub>2</sub>) and HBO<sub>2</sub> treatment on the endogenous production of the inflammatory markers interleukin (IL)-6, tumor necrosis factor (TNF)-α and IL-10, and on mortality in rats with cecal ligation and puncture (CLP) induced sepsis.
