We investigated whether plasma levels of the inflammation marker S100A8/A9, could predict acutekidney injury (AKI) onset in patients undergoing cardiac surgery necessitating cardiopulmonary bypass(CPB). Patients & methods: Plasma levels of S100A8/A9 and other neutrophil cytosolic proteins were measured in 39 patients pre- and immediately post-CPB. Results: All markers increased significantly post-CPBwith S100A8/A9, S100A12 and myeloperoxidase levels significantly higher in patients who developed AKIwithin 7 days. S100A8/A9 had good prognostic utility for AKI, with an area under the receiver operating characteristic curve of 0.81 (95% CI: 0.676–0.949) and a cut-off value of 10.6 μg/ml (85.7% sensitivityand 75% specificity) irrespective of age. Conclusion: Plasma S100A8/A9 levels immediately after cardiacsurgery, can predict onset of AKI, irrespective of age.

Mohiaddin H, Wong TDFK, Burke-Gaffney A, Bogle RGet al., 2018, Drug-coated balloon-only percutaneous coronary intervention for the treatment of De novo coronary artery disease: a systematic review, Cardiology and Therapy, Vol: 7, Pages: 127-149, ISSN: 2193-6544

Percutaneous coronary intervention (PCI) with a drug coated balloon (DCB) is a novel treatment which seeks to acutely dilate a coronary stenosis and deliver an anti-proliferative drug to the vessel wall (reducing the risk of re-stenosis), without implanting a drug eluting stent (DES). In this study, we performed a systematic review of stentless DCB-only angioplasty in de novo coronary artery disease. We identified 41 studies examining the effects of DCB-only PCI in a variety of clinical scenarios including small vessels, bifurcations, calcified lesions, and primary PCI. DCB-only PCI appears to be associated with comparable clinical outcomes to DESs and superior angiographic outcomes to plain-old balloon angioplasty. Although current data are promising, there is still a need for further long-term randomized control trial data comparing a DCB-only approach specifically against a second- or third-generation DES. A 4-week period of dual antiplatelet therapy provides a real advantage for the DCB-only PCI approach, which is not possible with most DESs. Since rates of adverse clinical outcomes are very low for all PCI procedures attention should be turned to the development of robust endpoints with which to compare DCB-only PCI approaches to the standard treatment with a DES.

Background: Efficacy of drug-eluting balloons (DEB) for treatment of de novo coronary lesions remains controversial. The present systematic review and meta-analysis of randomised controlled trials assessed DEB with bare-metal stents (BMS) and also DEB with provisional bail-out stents (‘DEB-only’ strategy), to other conventional options: plain-old balloon angioplasty (POBA), BMS and drug-eluting stents (DES).Methods: A systematic literature search from January 2000 until May 2017 was conducted. Primary outcome measure, late lumen loss (LLL); and secondary outcomes; binary restenosis, major adverse cardiac events (MACE), target lesion revascularization (TLR), myocardial infarction (MI), cardiovascular death and stent thrombosis were analysed.Results: Seventeen RCTs were included with 2,616 patients. Several comparative groups showed significant differences. DEB with BMS were inferior to DES for LLL [mean difference (MD) =0.12 mm; 95% confidence interval (CI), 0.03 to 0.22; P=0.01]; and binary restenosis [risk ratio (RR) =1.89; (CI, 1.13 to 3.18); P=0.02]. DEB with BMS was superior to BMS for LLL [MD =−0.27 mm; (−0.45 to −0.10); P=0.002]; and MACE [RR =0.64; (0.46 to 0.90); P=0.010]. Finally, DEB alone was superior to POBA for LLL [MD =−0.39 mm; (−0.67 to −0.11); P=0.006] and binary restenosis [RR =0.20; (0.05 to 0.85); P=0.03] in bifurcation lesions.Conclusions: The results of this meta-analysis showed that whilst DEB with BMS is superior to BMS alone, the combination is inferior to DES for treatment of de novo coronary lesions. Thus, DEB + BMS should not be applied in de novo lesions unless in patients who have absolute contraindications to DES. DEB alone, however, should be considered for relative contraindications to DES such as small vessel disease and bifurcation lesions.

Objective: Endothelial dysfunction associated with systemic inflammation can contribute to organ injury/failure followingcardiac surgery requiring cardiopulmonary bypass (CPB). Roundabout protein 4 (Robo4), an endothelial-expressedtransmembrane receptor and regulator of cell activation, is an important inhibitor of endothelial hyper-permeability. Weinvestigated the hypothesis that plasma levels of Robo4 are indicative of organ injury, in particular acute kidney injury (AKI),after cardiac surgery.Methods: Patients (n = 32) undergoing elective cardiac surgery with CPB were enrolled, prospectively. Plasma Robo4concentrations were measured pre-, 2 and 24 h post-operatively, using a commercially available ELISA. Plasma andendothelial markers of inflammation [interleukin (IL) -6, -8, -10: von Willibrand factor (vWF) and angiopoeitin-2 (Ang-2)] andthe AKI marker, neutrophil gelatinase-associated lipocalin (NGAL), were also measured by ELISA.Results: Plasma Robo4 increased significantly (p,0.001) from pre-operative levels of 25156904 pg/ml to 447361915 pg/ml, 2 h after surgery; and returned to basal levels (26826979 pg/ml) by 24 h. Plasma cytokines, vWF and NGAL alsoincreased 2 h post-operatively and remained elevated at 24 h. Ang-2 increased 24 h post-operatively, only. There was apositive, significant correlation (r = 0.385, p = 0.0298) between Robo-4 and IL-10, but not other cytokines, 2 h postoperatively.Whilst raised Robo4 did not correlate with indices of lung dysfunction or other biomarkers of endothelialactivation; there was a positive, significant correlation between raised (2 h) plasma NGAL and Robo4 (r = 0.4322, p = 0.0135).When patients were classed as AKI or non-AKI either using NGAL cut-off of 150 ng/ml, or the AKI Network (AKIN) clinicalclassification; plasma Robo4 was significantly higher (p = 0.0073 and 0.003, respectively) in AKI vs. non-AKI patients (NGALcut-off: 535062191 ng/ml, n = 16 vs. 359561068 pg/ml, n = 16; AKIN: 6546 pg/ml, IQR 5025–8079, n

Purpose: To investigatedifferences in cytokine/chemokinerelease in response to lipoteichoicacid (LTA) or lipopolysaccharide(LPS) and contributing cellularmechanisms, in order to improveunderstanding of the pathogenesis ofsepsis. Methods: Levels of cytokines/chemokineswere measured inplasma and peritoneal lavage fluid of10-week-old male mice (C57/B16)following intraperitoneal injection ofLTA or LPS (250 lg), and in supernatantsof murine J774.2 cells,immortalised blood monocytes, orisolated human monocytes treatedwith LTA or LPS (0–10 lg/ml). Therole of cytokine/chemokine messengerRNA (mRNA) stability versusnuclear factor-kappaB (NF-jB) andactivator protein-1 (AP-1) in mediatingcytokine/chemokine release inJ774 cells was also assessed.Results: In mice, plasma levels ofkeratinocyte-derived chemokine(KC), macrophage inflammatoryprotein (MIP)-2, interleukin (IL)-10,interferon (IFN)-c and tumour necrosisfactor-alpha (TNF-a) andperitoneal lavage fluid levels of KC, MIP-2 and TNF-a increased signifi-cantly 1 h after LPS. Only KC andMIP-2 levels increased 1 h after LTA.LPS-treated (10 lg/ml) J774 cellsreleased MIP-2, IL-10, IFN-c andTNF-a but not KC (24 h), whereascells treated with 10 lg/ml LTAreleased only MIP-2. LPS-stimulatedhuman monocytes released IL-10 andIL-8 (24 h); by contrast, LTA-treatedcells released only IL-8. LPS andLTA activated NF-jB and AP-1 inJ774 cells. The protein synthesisinhibitor cycloheximide abolishedLPS-induced IL-10 mRNA expressionand increased LTA- and LPSinducedmRNA for MIP-2 in J774cells. Conclusion: LTA and LPS, atclinically relevant concentrations,induced differential cytokine/chemokinerelease in vitro and in vivo, viaeffects distal to activation of NF-jB/AP-1 that might include chromatinremodelling or mRNA stability.

PURPOSE: To establish the relationship between plasma levels of thioredoxin (Trx) and macrophage migration inhibitory factor (MIF) in systemic inflammatory stress syndrome (SIRS)/sepsis. METHODS: Enzyme-linked immunosorbent assay measurements of Trx, MIF, IL-6, -8, and -10 and enzyme-linked fluorescent assay determination of procalcitonin (PCT) in plasma from patients with SIRS/sepsis, neutropenic sepsis, healthy volunteers and pre-oesophagectomy patients. RESULTS: Thioredoxin was significantly higher in SIRS/sepsis patients [101.3 ng ml(-1), interquartile range (IQR) 68.7-155.6, n = 32] compared with that in healthy controls (49.5 ng ml(-1), IQR 31.4-71.1, P < 0.001, n = 17) or pre-oesophagectomy patients (40.5 ng ml(-1), IQR 36.9-63.2, P < 0.01, n = 7), but was not raised in neutropenics (n = 5). MIF levels were also significantly higher in SIRS/sepsis patients (12.1 ng ml(-1), IQR 9.5-15.5, n = 35), but not in the neutropenic group, when compared with healthy controls (9.3 ng ml(-1), IQR 7.3-10.7, P < 0.01, n = 20). Trx levels correlated, positively, with MIF levels and APACHE II scores. Plasma levels of IL-6, -8 and -10 and PCT increased significantly in patients with SIRS/sepsis (P < 0.001) and with neutropenic sepsis, but did not correlate with Trx or MIF levels. CONCLUSION: Plasma levels of Trx, MIF, IL-6, -8, -10 and PCT were raised in patients with SIRS/sepsis. Comparisons between mediators suggest a unique correlation of Trx with MIF. Moreover, Trx and MIF differed from cytokines and PCT in that levels were significantly lower in patients with neutropenia compared with the main SIRS/sepsis group. By contrast, IL-8 and PCT levels were significantly greater in the neutropenic patient group. The link between MIF and Trx highlighted in this study has implications for future investigations into the pathogenesis of SIRS/sepsis.
