Modulation of Molecular Fingerprinting in Pediatric Sepsis
Systemic Inflammatory Response SyndromeThe goal of this study is to demonstrate the sensitivity and specificity of detecting circulating micro RNA (miRNA) biomarkers in pediatric septic patients. It will also follow expression and modulation of levels in response to therapy in comparison to current biomarkers.
The Importance of Adrenomedullin (AM) on ACTH-Cortisol-Glucose Axis
Systemic Inflammatory Response SyndromeHyperglycemiaHyperglycemia is frequent manifestations of the human metabolic response to systemic inflammatory response syndrome (SIRS),sepsis and septic shock, and are implicated in the clinical outcome. Adrenomedullin is elevated in SIRS, sepsis and septic shock and has been demonstrated the inhibitory role on insulin and adrenocorticotropic hormone secretion. Our hypothesis is that: AM elevation after SIRS could be the responsible to maintain hyperglycemia
Platelets as Regulators of Inflammation in Cardiac Surgery
Systemic Inflammatory Response SyndromeAcute Kidney InjuryPlatelets are increasingly recognized as a potent and ubiquitously present source of inflammatory activation. Importantly, antiplatelet therapy has been shown to significantly reduce major adverse events such as renal injury in cardiac surgery patients. However, in current practice, concerns of excessive bleeding-not platelet activation and thrombosis-shape clinical decisions. The investigators have recently seen, that a significant drop in platelet numbers following cardiac surgery is associated with increased mortality and risk of acute kidney injury. The investigators hypothesize that such thrombocytopenia is a result of excessive perioperative platelet activation and resultant release of inflammatory and tissue injurious signals by activated platelets. Platelet activation will be characterized during and after cardiac surgery and examine its correlation with inflammatory responses and perioperative end-organ injury.
Persistent Multiorgan Failure in Intensive Care Units
Systemic Inflammatory Response SyndromeSepsis1 moreMultiorgan failure (MOF) as a result of any critical condition is a complex set of immunological and biochemical interactions leading to death in patients who are effectively subjected to primary resuscitation (correction of circulatory hypoxia in trauma and blood loss, restoration of blood circulation after operations with artificial circulation. The frequency of MOF varies depending on the primary diagnosis of a critical patient and, according to a number of authors, is 60% for sepsis, and for severe co-occurring trauma up to 40% of all critical patients. However, if one remembers that the MOF is verified only by clinical scales of assessing the severity of the patient's condition, which presupposes the presence of the already existing pathophysiological mechanisms of MOF as multi-organ dysfunction, it is possible to declare a 100% presence of MOF in all critical patients. The data of Graetz et al (2016) show that none of the available three variants of pathophysiological mechanisms (anomaly of microcirculation, persistent inflammation, immune suppression and catabolism, cellular hibernation and staning) have been unambiguously demonstrated, which also reflected the lack of effectiveness of methods therapy, proposed, based on the pathogenesis options for MOF. A so-called danger-model has a special place in the genesis of the persistence of the MOF, which justifies an active search for distress-associated and pathogen-associated molecular patterns for their objectification and probable elimination. The systemic inflammatory response in patients. included in the study, is not a primary infection. It is also important to determine the role of danger-associated molecular patterns (DAMP) in the genesis of immune suppression as the leading immunological phenotype of MOF in later periods and to evaluate the relationship between DAMP expression and immunosuppressive cells of monocyte origin. The study has a mixed (retro- and prospective) character.
Serum Level of Lipopolysaccharide-binding Protein (LBP) and Atherosclerosis in Hemodialysis Patients...
Systemic Inflammatory Response SyndromeBackground In hemodialysis (HD) patients, impaired gut barrier and alteration in microbiota in the gut is thought to increase the risk of bacterial translocation and chronic inflammation. Lipopolysaccharide-binding protein (LBP) is an acute-phase reactant that mediates immune responses triggered by microbial products. Our aim is to investigate the relationship between circulating levels of LBP, inflammatory markers and incident atherosclerotic vascular events in HD patients and follow-up this defined cohort for 3 years. Methods A total of 300 HD patients will be recruited. The LBP and inflammatory markers will be determined using immuoassay methods annually. A bioimpedance spectroscopy device will used for body fat composition measurement and measurements will be done annually. Arterial stiffness is evaluated by measuring PWV in the heart-femoral segment using an automatic waveform analyzer.
The Utility of Ischemia Modified Albumin (IMA) in Sepsis
SepsisSevere Sepsis2 moreThe purpose of this study is to determine if levels of ischemia modified albumin (IMA) in blood are elevated in patients with suspected infection and are predictive of severity of illness in patients with sepsis. In order to compare subjects with infection to those without infection who are representative of the ED population at each site, a group of non-infected control patients will be enrolled. Each hospital will enroll subjects with age (by decade) and sex matched controls to reflect the population of subjects suspected of infection.
Vitamin D and Critically Ill Patients
Systemic Inflammatory Response SyndromeSepsisThe higher rate of vitamin D deficiency is spotted among patients being hospitalized or in critical condition. Especially, vitamin D level below normal prolongs hospital stay and increases incidence of adverse prognosis and pushing up mortality of a number of diseases. However, it is remain unclear the relationship between vitamin D levels and critically ill, especially infection or sepsis. In this study, the investigators evaluate the significance of vitamin D for diagnosis and other relevant assessments of ICU cases, including vitamin D's relevance to sepsis, as well as its value in severity and prognosis assessment, high-performance liquid chromatography and tandem mass spectrometry was used to detect the quantification of the total 25(OH)D in serum of critically ill patients. The investigators speculate that measurement of vitamin D could be taken as an indicator for diagnosis and assessment in critically ill patients.
The Role of Myristic Acid in Serum for Early Diagnosis of Sepsis and Comparison With Selected Biomarkers...
Sepsis SyndromeSystemic Inflammatory Response SyndromeThe aim of the study is to measure serum levels of myristic acid in septic patients and to compare them with myristic acid serum levels in patients with Systemic Inflammatory Response Syndrome of non infective etiology and in healthy volunteers. Furthermore, other biomarkers of sepsis are evaluated in comparison with microbiological findings detected either by standard hemocultures or by molecular biological methods.
Inflammatory Response During Anesthesia and Surgery
Systemic Inflammatory Response SyndromeMyocardial IschemiaThe purpose of this study is to investigate the effects of total intravenous anesthesia versus volatile anesthesia on the perioperative inflammatory response during and after major surgery.
Impact of Vitamin D Supplementation on Hepcidin Levels and Transfusion Requirements in Surgical...
Systemic Inflammatory Response SyndromeSepsis1 moreAcute inflammation induced by surgery and sepsis is complicated by the development of iron-restricted anemia due to the up-regulation of hepcidin. Excess hepcidin causes intracellular sequestration of iron, decreasing its availability for erythropoiesis. Hepcidin might be a potential target to reduce transfusion requirements in surgical and sepsis patients. Vitamin D supplementation might constitute a novel strategy to modulate the hepcidin-ferroportin-iron axis. Up to now, there are no data regarding the possibility that by using vitamin D supplementation in surgical and septic shock patients, the physicians could ameliorate anemia and, hence, reduce transfusion requirements. Aim: to conduct a randomised controlled trial to determine the impact of high-dose vitamin D enteral supplementation on serum hepcidin levels and transfusion requirements after major abdominal surgery and in septic shock patients.
