目的:探究血清降钙素原(PCT)、C-反应蛋白(CRP)与可溶性人髓系细胞触发受体-1(sTREM-1)在肺癌患者术后肺部感染中表达及其诊断价值。方法:选择2016年2月至2019年10月期间在我院行肺癌根治术的420例肺癌患者作为研究对象,根据术后患者是否发生肺部感染进一步划分为380例未感染组和40例感染组。感染组根据治疗结局进一步划分为29例治疗好转亚组与11例未好转亚组。采用酶联免疫吸附法检测各组的血清PCT、CRP与s TREM-1水平,采用受试者工作特征(ROC)曲线分析血清PCT、CRP和s TREM-1对肺癌患者术后肺部感染的预测价值。结果:与未感染组相比,感染组手术后血清PCT、CRP和s TREM-1水平均明显升高(P0.05)。与治疗好转亚组相比较,治疗未好转亚组手术后以及感染后血清PCT、CRP和s TREM-1水平均明显升高(P0.05)。ROC曲线显示,PCT的曲线下面积(AUC)为0.713,最佳截断值为1.23 ng/mL,灵敏度、特异度分别为0.81、0.79,准确度为0.82;CRP的AUC为0.752,最佳截断值为36.07 mg/L,灵敏度、特异度分别为0.83、0.81,准确度为0.83;s TREM-1的AUC为0.792,最佳截断值为20.58 pg/mL,灵敏度、特异度分别为0.86、0.84,准确度为0.85;PCT、CRP联合s TREM-1预测肺癌患者术后肺部感染的AUC为0.884,灵敏度、特异度分别为0.89、0.91,准确度为0.92。结论:肺癌根治术后肺部感染发生与患者血清PCT、CRP和s TREM-1水平相关,早期联合检测血清PCT、CRP和s TREM-1有助于预测肺癌根治术患者肺部感染发生风险,在肺癌根治术后肺部感染的预测和诊断中具有一定临床价值。     

"Inflammatory response to colloids compared to crystalloid priming in cardiac surgery patients with cardiopulmonary bypass"

"Cardiac surgery with cardiopulmonary bypass (CPB) induces a systemic inflammatory response syndrome that may contribute to postoperative morbidity and mortality. We investigated the in-flammatory responses to colloids compared to crystalloid priming in cardiac surgery patients with cardiopulmonary bypass. Thirty patients undergoing coronary artery bypass grafting (CABG) preparing for CPB were randomized into Ringer's solution (RS), 10% hydroxyethyl starch (HES) or 25% human albumin (HA) group. Serum concentrations of tumor necrosis factor-α (TNF-α), interleukin-1 β (IL-1β ), interleukin-6 (IL-6) and interleukin-10 (IL-10) were measured before CPB, at the end of CPB and 1, 6 and 12 h after CPB. Serum C-reactive protein (CRP) was determined pre-operatively and then daily for 2 days. Body-weight gain was significantly decreased on the day after surgery in the HES group than in the RS group. Volume priming in CPB for CABG patients using HA or HES preparation had less tendency for intense inflammatory response with lower levels of TNF-α, IL-1 β , IL-6 and higher levels of IL-10 compared to patients treated with RS. HES prime had lower levels of circulating CRP than in patients treated with HA or Ringer prime on the second post-operative day. Our data indicate that volume priming using colloid during CPB in CABG patients might exert beneficial effects on inflammatory responses."     

Tumour necrosis factor-alpha (TNFalpha) and interleukin-10 are crucial mediators in post-operative systemic inflammatory response and determine the occurrence of complications after major abdominal surgery

BACKGROUND: The course of serum cytokine levels in patients with postoperative systemic inflammatory response syndrome (SIRS) after major abdominal surgery remains currently unclear. METHODS: Blood was sampled pre- and post-operatively and on days 1 and 2 in 40 patients undergoing major abdominal surgery. Concentrations of tumour necrosis factor-alpha (TNFalpha), interleukin (IL) -6, IL-8, and IL-10 were measured by the LINCOplex assay; those of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) by an enzyme immunoassay. RESULTS: Compared to their pre-operative values, sTREM-1 was elevated on day 2; TNFalpha on day 1; IL-6 and IL-10 post-operatively and on days 1 and 2; and IL-8 post-operatively and on day 1. The duration of operation correlated with TNFalpha and IL-10 at all sampling times, and with IL-6 post-operatively. There were no differences in cytokine concentrations between patients who exhibited post-operative complications and those who did not. IL-10/TNFalpha below 30 was found in all patients with complications (100%) and in 20 patients without complications (64.5%, p: 0.043). CONCLUSIONS: SIRS following major surgery is characterised by complex alterations in cytokine concentrations. The balance between TNFalpha and IL-10 seems to determine the occurrence of post-operative complications.     

血清TRAF-6、MCP-1、sTREM-1、IL-33水平与脓毒症严重程度及与合并急性肾损伤关系的临床分析

目的:探讨脓毒症患者血清肿瘤坏死因子受体相关因子(Tumor necrosis factor receptor-related factor,TRAF)-6、单核细胞趋化蛋白(Monocyte chemotactic protein,MCP)-1、可溶性髓样细胞触发受体(Soluble myeloid cell trigger receptor,s TREM)-1、白介素(Interleukin,IL)-33水平的变化及与病情严重程度及合并急性肾损伤(acute kidney injury, AKI)的相关性。方法:选择2014年2月到2018年7月在我医院ICU病房进行诊治的脓毒症患者145例,分析脓毒症相关性急性肾损伤(sepsis-associated AKI,SAKI)的发生情况,比较SAKI和非SAKI患者血清TRAF-6、MCP-1、s TREM-1、IL-33水平,采用Pearson相关分析血清TRAF-6、MCP-1、s TREM-1、IL-33含量与APACHEⅡ评分、SOFA评分的相关性,多因素logistic回归分析脓毒症患者发生SAKI的影响因素。结果:在145例患者中,发生SAKI者69例,发生率为47.6%。SAKI组患者的年龄、性别、原发病、白细胞(white blood cell,WBC)计数、C反应蛋白(C reactive protein,CRP)、降钙素原(procalcitonin,PCT)、体重指数、BUN、Scr与eGFR值与非SAKI组患者对比差异均无统计学意义(P0.05)。SAKI组患者APACHEⅡ评分、SOFA评分血清TRAF-6、MCP-1、s TREM-1、IL-33含水平含量均显著高于非SAKI组患者(P0.05)。Pearson相关性分析显示血清TRAF-6、MCP-1、s TREM-1、IL-33水平与SAKI患者的急性生理和慢性健康Ⅱ(acute physiology and chronic health evaluation II,APACHEⅡ)评分、序贯多器官功能障碍(sequential organ failure assessment,SOFA)评分均呈显著正相关性(P0.05)。logistic回归分析显示血清TRAF-6、MCP-1、s TREM-1、IL-33水平升高均为影响SAKI发生的独立危险因素(P0.05)。结论:血清TRAF-6、MCP-1、s TREM-1、IL-33水平与脓毒症严重程度显著相关,可能作为诊断和治疗SAKI的参考指标及干预靶点。     

Evaluation of mediators of oxidative stress and inflammation in patients with acute appendicitis

Context: This study aims to explore the potential of new inflammatory markers for improving the challenging diagnosis of acute appendicitis (AA).

Methods: Levels of IL-1, IL-6, IL-8, IL-10, CRP, INF-γ, and TNF-α in serum were measured in 73 patients with AA. Oxidative stress and antioxidant enzymes were analyzed.

Results: Serum levels of interleukins, TNF-α, and INF-γ were significantly elevated in patients with appendicitis (p?<?0.0001), except for IL-10, which presented decreased levels. There were no significant differences in SOD (p?=?0.29), CAT (p?=?0.19), or TBARS levels (p?=?0.18), whereas protein carbonyls presented significant increase (p?<?0.0001).

Conclusion: Evaluating these biomarkers could aid in diagnosing AA.     

Estimating the probability of bacterial infection using a novel biomarker among pediatric patients in the emergency department

Context: IL-27 is a novel biomarker to identify bacterial infection in children.

Objective: IL-27 was evaluated among pediatric emergency department (ED) patients and compared with procalcitonin (PCT).

Methods and results: Children undergoing blood, urine, or cerebrospinal fluid cultures had IL-27 and PCT assays performed. Bacterial infection was defined as a positive culture or a clinical diagnosis based on chart review. IL-27 and PCT were increased among patients with bacterial infection and demonstrated comparable AUC’s (0.62 versus 0.61). A decision tree incorporating IL-27, PCT, and white blood cell count improved the AUC (0.80).

Conclusion: IL-27 is a viable candidate biomarker to identify bacterial infection among ED patients and is comparable with PCT.

Prognosis of community acquired pneumonia (CAP): value of triggering receptor expressed on myeloid cells-1 (TREM-1) and other mediators of the inflammatory response

TREM-1 is an activating receptor expressed on the surface of neutrophils and mature monocytes when stimulated by bacteria or fungi, leading to amplification of the inflammatory response. Our objective is to analyze the prognostic value of serum sTREM-1 levels and other mediators of the inflammatory response, in patients hospitalized for CAP, and to compare its prognostic value with those of advanced age, pneumonia severity scores, Charlson index, nutritional status and severity of sepsis. METHODS: We included 226 patients with CAP, 145 males and 81 females, median age of 74 years. The following tests were performed: arterial blood gases and chest radiography, nutritional assessment, assessment of the severity of the sepsis, Pneumonia Severity Index (PSI) and CURB-65, and mediators of inflammation: TNF alfa, IL-6, IL-10, IL-1ra, LBP, sCD14, CRP, and sTREM-1. Mortality during admittance was defined as the sole end point. RESULTS: Twenty-eight of the two-hundred and twenty-six patients died (12.4%). On univariate analysis advanced age, dehydration, increased Na, low BMI, handgrip strength, serum albumin, prealbumin, IGF-1, lymphocyte count, conscious drowsiness, tachypnea, decreased PaO2, hypotension, creatinine, ASAT, LDH, severity of sepsis, a high PSI or CURB65, TNFalpha, IL-6, IL-10, IL-1ra, and sTREM-1 were related to mortality. Variables with an independent value were IGF-1, CURB-65, TREM-1, advanced age and IL-6. CONCLUSIONS: This study confirms the usefulness of TREM-1 in the diagnosis and prognosis of patients with CAP, which is independent of advanced age, other inflammation markers such as IL-6, severity index for CAP such as CURB-65 or PSI, severity of sepsis and nutritional status including IGF-1.     

Εx-vivo effect of dexamethasone on cytokine production from whole blood of septic patients: Correlation with disease severity

Background: Controversial findings of former clinical trials on the effect of low dose hydrocortisone in patients with septic shock led to investigate the effect of corticosteroids on the production of cytokines from endotoxin (LPS)-stimulated whole blood. Methods: Whole blood from 33 septic patients was sampled within 24 h alter diagnosis. Hydrocortisone was not administered during follow-up. Whole blood was stimulated with 30 ng/ml of LPS in the presence of 0.01, 0.1, 1 and 10 μM of dexamethasone. Concentrations of cytokines and of sTREM-1 were estimated in supernatants after six hours of incubation. Results: Dexamethasone inhibited LPS-stimulated release of ΤΝFα, of IL-6, of IL-8 and of IL-10 in dose-dependent manner. A dual effect on the kinetics of release of IL-1β and of sTREM-1 was shown. Release of IL-1β was either decreased, what was connected with unfavorable outcome, or it was unaffected what was connected with a favorable outcome. Release of sTREM-1 was either increased, what was connected with unfavorable outcome, or it was decreased what was connected with a favorable outcome. Conclusions: Part of the beneficiary effect of corticosteroids in sepsis may be due to an effect on the release of IL-1β and of sTREM-1. This effect does not seem to be homogeneous for all septic patients.     

A Biomarker Panel (Bioscore) Incorporating Monocytic Surface and Soluble TREM-1 Has High Discriminative Value for Ventilator-Associated Pneumonia: A Prospective Observational Study

Introduction

Ventilator-associated pneumonia (VAP) increases mortality in critical illness. However, clinical diagnostic uncertainty persists. We hypothesised that measuring cell-surface and soluble inflammatory markers, incorporating Triggering Receptor Expressed by Myeloid cells (TREM)-1, would improve diagnostic accuracy.

Methods

A single centre prospective observational study, set in a University Hospital medical-surgical intensive Care unit, recruited 91 patients into 3 groups: 27 patients with VAP, 33 ventilated controls without evidence of pulmonary sepsis (non-VAP), and 31 non-ventilated controls (NVC), without clinical infection, attending for bronchoscopy. Paired samples of Bronchiolo-alveolar lavage fluid (BALF) and blood from each subject were analysed for putative biomarkers of infection: Cellular (TREM-1, CD11b and CD62L) and soluble (IL-1β, IL-6, IL-8, sTREM-1, Procalcitonin). Expression of cellular markers on monocytes and neutrophils were measured by flow cytometry. Soluble inflammatory markers were determined by ELISA. A biomarker panel (‘Bioscore’), was constructed, tested and validated, using Fisher’s discriminant function analysis, to assess its value in distinguishing VAP from non VAP.

Results

The expression of TREM-1 on monocytes (mTREM-1) and neutrophils (nTREM-1) and concentrations of IL-1β, IL-8, and sTREM-1 in BALF were significantly higher in VAP compared with non-VAP and NVC (p<0.001). The BALF/blood mTREM-1 was significantly higher in VAP patients compared to non-VAP and NVC (0.8 v 0.4 v 0.3 p<0.001). A seven marker Bioscore (BALF/blood ratio mTREM-1 and mCD11b, BALF sTREM-1, IL-8 and IL-1β, and serum CRP and IL-6) correctly identified 88.9% of VAP cases and 100% of non-VAP cases.

Conclusion

A 7-marker bioscore, incorporating cellular and soluble TREM-1, accurately discriminates VAP from non-pulmonary infection.     

Elevated circulating inflammatory markers in female patients with cardiac syndrome X

Background. The pathophysiological mechanism in cardiac syndrome X has been suggested as impairment in normal endothelial function of the coronary microvasculature, resulting in inadequate flow reserve. However, despite the extensive studies, the precise mechanisms in cardiac syndrome X remain unclear. Purpose. The present study was, therefore, to investigate whether inflammatory cells and markers such as C-reactive protein (CRP) and interleukin-6 (IL-6) might be involved in the pathogenesis of cardiac syndrome X. Methods. Thirty-six female patients with cardiac syndrome X and 30 sex-matched normal controls were prospectively enrolled in this study. Blood samples were drawn for measuring white blood and monocyte cells, inflammatory markers such as CRP and IL-6, and data were compared between patients with cardiac syndrome X and normal controls. Results. The data showed that increased numbers of white blood and monocyte cells were found in patients with cardiac syndrome X compared with normal controls (white blood cells: 7072 ± 1146/mm³ vs. 6138 ± 1079/mm³; monocyte cells: 612 ± 186/mm³ vs. 539 ± 190/mm³ p < 0.05, respectively). Moreover, patients with cardiac syndrome X were detected to have significantly higher plasma CRP and IL-6 levels in comparison with patients with normal controls (CRP: 0.48 ± 0.26 mg/L vs. 0.22 ± 0.15 mg/L; IL-6: 13.4 ± 1.2 pg/dl vs. 6.2 ± 0.6 pg/dl, p < 0.01, respectively). The multivariate analysis showed that CRP was the independent variable most strongly associated with cardiac syndrome X. Conclusions. Our data suggested that low-grade, chronic inflammation might contribute to the development of cardiac syndrome X manifested by increased plasma levels of inflammatory cells and inflammatory markers.

Serum Levels of Inflammatory Markers in Depressed Elderly Patients with Diabetes and Mild Cognitive Impairment

Objective

The aim of the study was to determine the serum levels of CRP, IL-6 and TNF-α in elderly diabetic patients with depressive syndrome alone or with coexisting mild cognitive impairment (MCI).

Methods

276 diabetics elders were screened for depressive symptoms (using Geriatric Depression Scale: GDS-30) and MCI (using the Montreal Cognitive Assessment: MoCA score). Data of HbA1c, blood lipids and inflammatory markers levels were collected.

Results

In all groups of patients levels of CRP, IL-6 and TNF-α were significantly higher as compared to controls. The highest level of inflammatory markers was detected in group with depressive mood and coexisting MCI, however IL-6 level didn’t significantly differ as compared to MCI group. We founded correlations between all inflammatory markers in group of patients with depressive mood and in group of subjects with depressive symptoms and coexisting MCI. GDS-30 score was correlated with levels of inflammatory markers in group with depressive mood, and with levels of CRP and TNF-α in group with depressive mood and coexisting MCI. In the group with depressive mood and coexisting MCI we founded that MoCA score was negatively correlated with CRP and TNF-α levels; and HbA1c level was positively correlated with all inflammatory markers. The univariate logistic regression models revealed that variables which increased the likelihood of having been diagnosed with MCI in depressed patients were: higher levels of HbA1c, CRP, IL-6 and TNF-α, previous CVD or stroke, increased number of co-morbidities and microvascular complications, older age, less years of formal education. The multivariable model showed that previous CVD, higher HbA1c and IL-6 levels are significant factors.

Conclusions

We demonstrated that the presence of depressive syndrome is associated with higher levels of inflammatory markers in elderly patients with diabetes. The presence of MCI in these depressed subjects has additive effect on levels of inflammatory mediators.

Similar effects of general and spinal anaesthesia on perioperative stress response in patients undergoing haemorrhoidectomy

Surgery induces release of neuroendocrine hormones (cortisol), cytokines (interleukin-6: IL-6, tumour necrosis factor-alpha: TNF-alpha), acute phase proteins (C-reactive protein: CRP, leptin). We studied the effects of general and spinal anaesthesia on stress response to haemorrhoidectomy. Patients were assigned to general and spinal anaesthesia groups (n = 7). Blood samples were drawn before induction and 24 hours after surgery. Perioperative levels of IL-6, TNF-alpha, CRP, cortisol, and leptin were comparable among the groups. Twenty four hours after surgery, TNF-alpha and cortisol did not change; IL-6 and CRP increased significantly in all patients. Significant increase in leptin levels was found in patients undergoing spinal anaesthesia. Except for the increase in leptin levels, there was no significant difference related to the effects of general and spinal anaesthesia.

Three-year follow-up of Interleukin 6 and C-reactive protein in chronic obstructive pulmonary disease

Background

Past studies have shown that mean values of Interleukin-6 (IL-6) and C-reactive protein (CRP) do not change significantly in COPD patients over a one-year period. However, longer period follow-up studies are still lacking. Thus, the aim of this study is to evaluate plasma CRP and IL-6 concentration over three years in COPD patients and to test the association between these inflammatory mediators and disease outcome markers.

Methods

A cohort of 77 outpatients with stable COPD was evaluated at baseline, and 53 (mean FEV₁, 56% predicted) were included in the prospective study. We evaluated Interleukin-6 (IL-6), C-reactive protein (CRP), six-minute walking distance (6MWD), and body mass index (BMI) at baseline and after three years. Plasma concentration of IL-6 was measured by high sensitivity ELISA, and CRP was obtained by high sensitivity particle-enhanced immunonephelometry.

Results

IL-6 increased significantly after 3 years compared to baseline measurements [0.8 (0.5-1.3) vs 2.4 (1.3-4.4) pg/ml; p < 0.001] and was associated with worse 6MWD performance. In the Cox regression, increased IL-6 at baseline was associated with mortality [Hazard Ratio (95% CI) = 2.68 (0.13, 1.84); p = 0.02]. CRP mean values did not change [5 (1.6-7.9) vs 4.7 (1.7-10) pg/L; p = 0.84], although eleven patients (21%) presented with changes >3 mg/L in CRP after 3 years.

Conclusions

The systemic inflammatory process, evaluated by IL-6, seems to be persistent, progressive and associated with mortality and worse physical performance in COPD patients.

酚妥拉明联合亚胺培南西司他丁钠对重症肺炎患儿肺功能、炎性因子及血清sTREM-1、sICAM-1水平的影响

目的:研究酚妥拉明联合亚胺培南西司他丁钠对重症肺炎患儿肺功能、炎性因子以及血清可溶性髓系细胞触发受体-1(sTREM-1)、可溶性细胞间黏附分子-1(sICAM-1)水平的影响。方法:选择2018年9月至2019年10月在我院治疗的80例重症肺炎患儿,随机分为对照组(40例)和研究组(40例)。对照组给予静滴亚胺培南西司他丁钠,研究组在对照组基础上静滴酚妥拉明注射液。比较两组患儿临床疗效,对比两组患儿退热时间、肺啰音和咳嗽消失时间及住院时间,比较两组患儿治疗前后肺功能变化情况,测定并比较两组患儿治疗前后血清炎性因子水平变化及血清sTREM-1、sICAM-1水平变化。结果:研究组总有效率(92.50%)明显高于对照组(75.00%),差异具有统计学意义(P0.05);研究组退热时间、肺啰音及咳嗽消失时间和住院时间与对照组相比,均明显减少(P0.05);治疗后,研究组的动脉血氧分压(P_aO_2)和动脉/肺泡氧分压比值(a/APO_2)较对照组明显升高,二氧化碳分压(P_aO_2)较对照组明显降低(P0.05);治疗后,研究组血清白细胞介素(IL)-6、IL-8和C反应蛋白(CRP)及血清中sTREM-1、sICAM-1水平较对照组显著降低(P0.05)。结论:酚妥拉明联合亚胺培南西司他丁钠治疗重症肺炎患儿,可以明显提高肺功能,降低炎性因子水平,降低血清中sTREM-1和sICAM-1水平,促进症状好转,提高疗效,减少住院时间。
