The aim was to investigate: changes of inflammatory, stress and cardiac response in patients undergoing open heart surgeries up to five days after the procedure; the association between inflammatory, stress and cardiac response and whether changes in a certain marker can predict short-term patient outcome. Ninety patients were divided into three groups, 30 participants each (on-pump, off-pump revascularization and valve replacement group). The following markers were measured: complete blood count, CRP, IL-6, IL-10, leptin, resistin, monocyte chemoattractant protein-1 (MCP-1), cortisol, CK and hsTnT in 5 points. Resistin increased in all three groups. Lower IL-10 levels were found after the surgery and higher levels of leptin and MCP-1 in the off-pump than in the on-pump group. Off-pump group had higher values of IL-6, IL-10, leptin, resistin and MCP-1 and lower levels of CK and hsTnT 24 after surgery than the on-pump group. We found significant correlation between MCP-1 and resistin. The difference between resistin at time points 2 and 3 significantly predicted transfusion needs; while the difference between CRP and resistin before and at the end of the surgery together with the difference between leukocytes at the end and 24 hours after the surgery predicted the use of inotropic agents/vasopressors. Cardiac surgeries cause an increase of inflammatory, stress and cardiac markers. Only resistin correlated with MCP-1 which confirms the link between resistin secreted form infiltrated macrophages and enhanced release of MCP-1.

ABSTRACT We have previously reported that differences in early production of interleukin 12 (IL-12) by dendritic cells (DC) underlies the difference between the susceptibilities to Listeria monocytogenes of C57BL/6 and BALB/c mice. To elucidate mechanisms for the different abilities of DC to produce cytokine in C57BL/6 and BALB/c mice, we examined Toll-like receptor (TLR) expression by DC and their responses in vitro to known microbial ligands for TLRs. We found that DC isolated from the spleens of naive C57BL/6 mice preferentially expressed TLR9 mRNA, whereas DC from naive BALB/c mice strongly expressed TLR2, -4, -5, and -6 mRNAs. C57BL/6 DC produced a higher level of IL-12p40 in response to the ligands for TLR4 (lipopolysaccharide), TLR2 (lipoprotein), and TLR9 (CpG), whereas BALB/c DC responded to these ligands by producing a larger amount of monocyte chemoattractant protein 1. C57BL/6 DC expressed higher levels of CD40 and Stat4 than BALB/c DC did, suggesting that naive C57BL/6 mice contained more-mature subsets of DC than naive BALB/c mice. Differences in reactivities of DC to microbial molecules through TLRs may be associated with susceptibility and resistance to Listeria infection in BALB/c and C57BL/6 mice.

Abstract OBJECTIVES Both off-pump coronary artery bypass grafting surgery (OPCABG) and mini-extracorporeal circulation (MECC) have been associated with lower morbidity and mortality and less inflammation than conventional cardiopulmonary bypass. However, studies comparing the 2 techniques are scarce and the results are controversial. We compared the clinical outcomes and inflammatory response of low-risk patients undergoing coronary bypass grafting with MECC versus OPCABG. METHODS We conducted a prospective, randomized study in patients undergoing coronary heart surgery. Two hundred and thirty consecutive low-risk patients were randomly assigned to either receive OPCABG (n = 117) or MECC (n = 113). Clinical outcomes and postoperative biochemical results were analysed in both groups. We also analysed 19 circulating inflammatory markers in a subgroup of 40 patients at 4 perioperative time points. The area under the curve for each marker was calculated to monitor differences in the inflammatory response. RESULTS No significant differences were found between groups regarding perioperative clinical complications and no deaths occurred during the trial. Plasma levels in 9 of the 19 inflammatory markers were undetectable or showed no temporal variation, 3 were higher in the MECC group [interleukin (IL)-10, macrophage inflammatory protein-1β and epidermal growth factor] and 7 were higher in the OPCABG group (growth regulator oncogene, IL-6, IL-8, soluble CD40 ligand, monocyte chemoattractant protein-1, monocyte chemoattractant protein-3 and tumour necrosis factor-α). Differences in 2 proinflammatory cytokines, IL-6 and monocyte chemoattractant protein 1, between the 2 surgical procedures were statistically significant. CONCLUSIONS No clinical differences were observed between in low-risk patients undergoing MECC or OPCABG surgery, but OPCABG was associated with an increased release of proinflammatory cytokines compared with MECC. Studies in larger cohorts and in patients at higher risk are needed to confirm these findings. Clinical trial registration number NCT02118025.
