  • Effect of Clinical Nutritional Supplementation for Systematic Inflammatory Response Syndrome: A Systematic Review

    Objective To assess the effect and safety of clinical nutritional supplementation with different patterns for treating systematic inflammatory response syndrome (SIRS). Methods Randomized controlled trials (RCTs) were identified from MEDLINE (1996 to Nov. 2004), EMBASE (1984 to Nov. 2002), Cochrane Controlled Trials Register (Issue 4, 2004), Chinese Cochrane Centre Database (Issue 4, 2004), CBMdisc (1978 to Nov. 2004). We handsearched related published and unpublished data and their references. All RCTs of nutritional interventions for SIRS were included. Data were extracted and evaluated by two reviewers independently with designed extraction form. RevMan 4.2.7 software was used for data analysis. Results Six RCTs involving 353 patients were included. All the results of meta-analysis were listed as the following: ① Mortality: compared with routine nutrition, one study showed that glutamine had a statistical difference with RR 0.67 and 95%CI 0.31 to 1.32. Compared with no treatment, one study showed selenium had a statistical difference with RR 1.19, 95%CI 0.59 to 2.41. ② Compared with routine nutrition, one study showed that glutamine had a statistical difference on reducing the ratio of nasocomial infection of SIRS with RR 0.5, 95%CI 0.27 to 0.91, but had no statistical difference on reducing the ratio of multiple organ dysfunction syndrome with RR 1.53, 95%CI 0.64 to 3.66. ③ Improvement of the critical condition of SIRS: compared with routine nutrition, one study showed that glutamine had a statistical differences with WMD 4.0, 95%CI 2.36 to 5.64; compared with high calorie intake, two studies showed low calorie intake had a statistical difference with WMD 4.9, 95%CI 1.76 to 8.04. ④ Reduction of the complication of hyperglycemia and hypertriglyceridemia: compared with high calorie intake, one study showed low calorie intake had statistical difference with WMD -0.70, 95%CI -1.20 to -0.20 and WMD -1.80, 95% CI -2.42 to -1.16 respectively and all P≤0.01. ⑤ Increasing of the plasma IgG concentration: compared with routine nutrition, two studies showed that glutamine had a statistical difference with WMD 4.20, 95% CI 2.23 to 6.16. ⑥ Increasing of the nitrogen balance, intestinal permeability, the level of plasma concentration of anlbumin, prealbumin and TRF: compared with control interventions, glutamine, low calorie intake, selenium supplementation and fructose-glucose-xylitol mixture showed no statistical difference. Conclusions Glutamine, low calorie intake, selenium supplementation, FGX mixture may decrease the complication of infection or metabolism and be better than the controlled interventions; but there is no benefit on reducing the rate of death result from SIRS compared with controlled interventions. The evidence of most RCTs with poor quality is too weak to draw a conclusion. More high quality trials are required.

  • Study about Bacterial Translocation

    【Abstract】ObjectiveThere are two main functions of gastrointestinal tract, digestion and absorption, and barrier function. The latter has an important defensive effect, which keeps the body away from the invading and damaging of bacteria and endotoxin. It maintains the systemic homeostasis. Intestinal dysfunction would happen when body suffers from diseases or harmful stimulations. The more serious intestinal disorders would harm the intestinal protective mechanism, or intestinal barrier function, and bacterial/endotoxin translocation, of intestinal failure (IF) would ensue. This article provides a critical review of the evidence indicating that an increase in bacterial translocation is associated with sepsis, and even the multiple organ failure syndrome in critically ill patients. The intransit microorganisms play an essential role in the homeostasis of local and systemic immunity. MethodsAll studies published from 2000 to June 2005 about intestinal permeability, bacterial translocation, and systemic inflammatory response syndrome were located by search of PubMed. ResultsClinical and experimental studies investigating the correlation between bacterial translocation and systemic inflammatory response syndrome, associated with the damage of the gut barrier function . To keep the mucosal barrier function intact is one of the main issues in the prevention of bacterial translocation. This could be achieved by the adequate delivery of oxygen and nutrient supplementation to the gut. Enteral nutrition, probiotic can be a good choice. ConclusionWith a better understanding of the bacteriahost interactions in health and the alterations induced by critical illness, new therapies that improve the environment of both may lead to better recovery rates in intensive care unit patients.

  • Experimental Study on Effect of Salvia Miltiorrhiza and Shengmai Injection in Treating Systemic Inflammatory Response Syndrome

    【Abstract】ObjectiveTo investigate the effect of Salvia Miltiorrhiza (SM) and Shengmai injection (SI) in treating systemic inflammatory response syndrome (SIRS) and their mechanism. Methods The animal model of SIRS was established by injectinglipopolysaccharide(LPS, 1 mg/kg)intraperitoneally. Forty Wistar rats were randomly divided into four groups: control group, SM group, SI group and combined treatment group (SM+SI group), which were treated with normal saline(5 ml/kg) plus LPS(1 mg/kg), SM(5 ml/kg)plus LPSKG4(1 mg/kg), SI(5 ml/kg)plus LPS(1 mg/kg), SM(2.5 ml/kg) plus SI(2.5 ml/kg) and LPS(1 mg/kg) respectively. Six rats of each group were sacrificed for sample collection of blood, liver, lung and kidney 8 hours after LPS injection. Blood routine, serum TNF-α and IL-6 were measured. Specimen of organs were fixed in formalin and sent for routine pathological examination. The survival of other 4 rats of each group were observed untill 48 hours after LPS injection. SPSS 10.0 was used in statistical analysis. Results Two rats in control group died 13 hours and 22 hours after LPS injection respectively, the remaining 2 rats in this group and the rats in other 3 groups survived 48 hours after LPS injection. The white blood cell count of control group was significantly higher than that of other groups. The serum TNF-α and IL-6 of control group were significantly more than those of other groups. Pathological damages were found in all groups, and the most severe ones were in control group. SM and SI could decrease the level of serum TNF-α and IL-6 in the process of LPS-stimulated SIRS, down-regulate the severe inflammatory response, attenuate organ damages of the liver, lung and kidney, and increase forty-eihgt-hour survival rate obviously. Conclusion The experiment provides a theoretical base for clinical use of SM and SI in treatment of SIRS.

  • Clinical value of peripheral serum cf-DNA/NETs level in diagnosis and severity assessment of sepsis patients

    Objective To investigate the clinical value of peripheral serum cell-free DNA/neutrophil extracellular traps (cf-DNA/NETs) level in diagnosis and severity assessment of sepsis patients. Methods Forty patients with sepsis and 40 patients with non-infectious systemic inflammatory response syndrome (nf-SIRS) were enrolled in this study. The cf-DNA/NETs level in serum of all subjects were measured. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic ability of the cf-DNA/NETs, white blood cell count (WBC), procalcitonin (PCT) and interleukin-6 (IL-6). The sepsis patients were stratified into a survival group and a death group according to the prognosis. Sequential organ failure (SOFA) score were recorded in the sepsis patients, and the correlations between SOFA and cf-DNA/NETs, PCT, WBC, IL-6 were analyzed. Results Compared with the nf-SIRS group, cf-DNA/NETs and PCT levels were significantly higher in the sepsis group (both P<0.05). WBC and IL-6 showed no significant differences between the two groups (bothP>0.05). The area under the ROC curve (AUC) of cf-DNA/NETs was 0.884 for diagnosis of sepsis, and it was higher than the AUC of PCT (0.803). The cf-DNA/NETs showed better sensitivity (81.2% and 79.2%) and specificity (81.0% and 82.4%) than PCT. cf-DNA/NETs and PCT were significantly higher in the death group than those in the survival group. Bivariate collection analysis revealed positive correlations between SOFA score and the two biomarkers of cf-DNA/NETs and PCT (r1=0.573, r2=0.518; both P<0.01). Conclusions cf-DNA/NETs and PCT have certain value in early diagnosis of sepsis, and cf-DNA/NETs shows better diagnostic value in distinguishing sepsis from nf-SIRS than PCT. cf-DNA/NETs can be used as a routine monitoring index to help assess disease severity in sepsis.

  • Research progress on acute lung injury and lung protective strategies by cardiopulmonary bypass

    Acute lung injury is a kind of common complication after cardiopulmonary bypass. Acute lung injury is attributed to the ischemia-reperfusion injury and systemic inflammatory response syndrome. Several factors common in cardiac surgery with cardiopulmonary bypass may worsen the risk for acute lung injury including atelectasis, transfusion requirement, older age, heart failure, emergency surgery and prolonged duration of bypass. Targets for prevention of acute lung injury include mechanical, surgical and anesthetic interventions that aim to reduce the contact activation, systemic inflammatory response, leukocyte sequestration and hemodilution associated with cardiopulmonary bypass. We aim to review the etiology, risk factors and lung protective strategies for acute lung injury after cardiopulmonary bypass.

  • Clinical value of PCT, WBC, and CRP in diagnosis of common bile duct stones with bile duct infection and systemic inflammatory response syndrome

    ObjectiveTo study the clinical value of procalcitonin (PCT), WBC count, and C-reactive protein (CRP) in diagnosis of common bile duct stones with acute bile duct infection and systemic inflammatory response syndrome (SIRS).MethodsA total of 80 patients with bile duct stones were retrospectively analyzed, which were divided into two groups, SIRS group (n=40) and non-SIRS group (n=40). The numerical value of PCT, WBC count, and CRP were detected on 1, 4, and 7 day after admission, and calculated the score of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) on 1 day after admission. Then analyzed the clinical value of PCT, WBC count, and CRP in diagnosis of common bile duct stones with acute bile duct infection and SIRS.ResultsEach area under the ROC curve of PCT, CRP, and WBC count were 0.81, 0.78, and 0.72, respectively, with significant difference (P<0.05). The PCT, CRP, and WBC count had a certain accuracy in diagnosis of common bile duct stones with acute bile duct infection and SIRS. The positive-relationship between PCT, CRP, WBC count and APACHE Ⅱ score was significant (r=0.91, P<0.01; r=0.88, P<0.01; r=0.69, P<0.01).ConclusionTo detect the numerical value of PCT, WBC count, and CRP had significant clinical value in diagnosis of common bile duct stones with acute bile duct infection and SIRS.

  • Evaluation on the predictive values of six critical illness scores for ICU mortality in respiratory intensive care unit based on MIMIC-Ⅲ database

    ObjectiveTo evaluate the predictive value of critical illness scores for hospital mortality of severe respiratory diseases in respiratory intensive care unit (ICU).MethodsThe clinical data of the patients who needed intensive care and primary diagnosed with respiratory diseases from June, 2001 to Octomber, 2012 were extracted from MIMIC-Ⅲ database. The Acute Physiology Score (APS) Ⅲ, Simplified Acute Physiology Score (SAPS) Ⅱ, Oxford Acute Severity of Illness Score (OASIS), Logistic Organ Dysfunction System (LODS), Systemic Inflammatory Response Syndrome (SIRS) and Sequential Organ Failure Assessment (SOFA) were calculated according to the requirements of each scoring system. ICU mortality was set up as primary outcome and receiver operating characteristic (ROC) analysis was performed to evaluate the predictive performances by comparing the areas under ROC curve (AUC). According to whether they received invasive mechanical ventilation during ICU, the patients were divided into two groups (group A: without invasive mechanical ventilation group; group B: with invasive mechanical ventilation group). The AUCs of six scoring systems were calculated for groups A and B, and the ROC curves were compared independently.ResultsA total of 2988 patients were recruited, male accounted for 49.4%, median age was 67 (55, 79), and ICU mortality was 13.2%. The AUCs of SAPSⅡ, LODS, APSⅢ, OASIS, SOFA and SIRS were 0.73 (0.70, 0.75), 0.71 (0.68, 0.73), 0.69 (0.67, 0.72), 0.69 (0.67, 0.72), 0.67 (0.64, 0.70) and 0.58 (0.56, 0.62). Subgroup analysis showed that in group A, the AUCs of OASIS, SAPSⅡ, LODS, APSⅢ, SOFA and SIRS were 0.81 (0.76, 0.85), 0.80 (0.75, 0.85), 0.77 (0.72, 0.83), 0.75 (0.70, 0.80), 0.73 (0.68, 0.78) and 0.63 (0.56, 0.69) in the prediction of ICU mortality; in group B, the AUCs of SAPSⅡ, APSⅢ, LODS, SOFA, OASIS and SIRS were 0.68 (0.64, 0.71), 0.67 (0.63, 0.70), 0.65 (0.62, 0.69), 0.62 (0.59, 0.66), 0.62 (0.58, 0.65) and 0.57 (0.54, 0.61) in the prediction of ICU mortality. The results of independent ROC curve showed that the AUC differences between groups A and B were statistically significant in terms of OASIS, SAPSⅡ, LODS, APSⅢ and SOFA, but there were no significant differences in SIRS.ConclusionsThe predictive values of six critical illness scores for ICU mortality in respiratory intensive care are low. Lack of ability to predict ICU mortality of patients with invasive mechanical ventilation should hold primary responsibility.
