Cím:Clustering identifies endotypes of traumatic brain injury in an intensive care cohort : a CENTER-TBI study / Ảkerlund Cecilia A. I., Holst Anders, Stocchetti Nino, Steyerberg Ewout W., Menon David K., Ercole Ari, Nelson David W., CENTER-TBI Participants and Investigators

Megjegyzések:Abstract Background: While the Glasgow coma scale (GCS) is one of the strongest outcome predictors, the current classifcation of traumatic brain injury (TBI) as ♭mild', ♭moderate' or ♭severe' based on this fails to capture enormous heterogeneity in pathophysiology and treatment response. We hypothesized that data-driven characterization of TBI could identify distinct endotypes and give mechanistic insights. Methods: We developed an unsupervised statistical clustering model based on a mixture of probabilistic graphs for presentation (<24 h) demographic, clinical, physiological, laboratory and imaging data to identify subgroups of TBI patients admitted to the intensive care unit in the CENTER-TBI dataset (N=1,728). A cluster similarity index was used for robust determination of optimal cluster number. Mutual information was used to quantify feature importance and for cluster interpretation. Results: Six stable endotypes were identifed with distinct GCS and composite systemic metabolic stress profles, distinguished by GCS, blood lactate, oxygen saturation, serum creatinine, glucose, base excess, pH, arterial partial pressure of carbon dioxide, and body temperature. Notably, a cluster with ♭moderate' TBI (by traditional classifcation) and deranged metabolic profle, had a worse outcome than a cluster with ♭severe' GCS and a normal metabolic profle. Addition of cluster labels signifcantly improved the prognostic precision of the IMPACT (International Mission for Prognosis and Analysis of Clinical trials in TBI) extended model, for prediction of both unfavourable outcome and mortality (both p<0.001). Conclusions: Six stable and clinically distinct TBI endotypes were identifed by probabilistic unsupervised clustering. In addition to presenting neurology, a profle of biochemical derangement was found to be an important distinguishing feature that was both biologically plausible and associated with outcome. Our work motivates refning current TBI classifcations with factors describing metabolic stress. Such data-driven clusters suggest TBI endotypes that merit investigation to identify bespoke treatment strategies to improve care. Trial registration The core study was registered with ClinicalTrials.gov, number NCT02210221, registered on August 06, 2014, with Resource Identifcation Portal (RRID: SCR_015582)

Cím:Cerebral vasoreactivity to acetazolamide is not impaired in patients with severe sepsis / Béla Fülesdi, Szilárd Szatmári, Csaba Antek, Zoltán Fülep, Péter Sárkány, László Csiba, Csilla Molnár
Dátum:2012
ISSN:0883-9441
Megjegyzések:Introduction: The pathophysiology of sepsis-associated encephalopathy (SAE) is not entirely clear, butone of the possible underlying mechanisms is the alteration of the cerebral microvascular function. Theaim of the present work was to test whether cerebral vasomotor reactivity is impaired in patients withsevere sepsis.Methods: Patients fulfilling the criteria of clinical sepsis and showing at least 2 organ dysfunctions wereincluded (n = 16). Nonseptic healthy persons without previous diseases affecting cerebral vasoreactivityserved as controls (n = 16). Transcranial Doppler blood flow velocities were measured at rest and at 5,10, 15, and 20 minutes after intravenous administration of 15 mg/kg acetazolamide. The time course ofthe acetazolamide effect on cerebral blood flow velocity (cerebrovascular reactivity [CVR]) and themaximal vasodilatory effect of acetazolemide (cerebrovascular reserve capacity [CRC]) were comparedamong the groups.Results: Absolute blood flow velocities after administration of the vasodilator drug did not differbetween control and septic patients. Assessment of the time course of the vasomotor reaction showedthat patients with sepsis reacted in a similar fashion to the vasodilatory stimulus than control persons.When assessing the maximal vasodilatory ability of the cerebral arterioles to acetazolamide duringvasomotor testing, we found that there was no difference in vasodilatory ability between septic andhealthy subjects (CRC controls, 54.8% ? 11.1%; CRC sepsis-associated encephalopathy, 61.1% ?34.4%; P = .49).Conclusions: We conclude that cerebrovascular reactivity is not impaired in patients with severe sepsis.It is conceivable that cerebral vasoreactivity may be differently involved at different severity stages ofthe septic process.

Cím:Protective effect of a novel, potent inhibitor of poly(adenosine 5'-diphosphate-ribose) synthetase in a porcine model of severe bacterial sepsis / Goldfarb, R. D., Marton, A., Szabo, E., Virag, L., Salzman, A. L., Glock, D., Akhter, I., McCarthy, R., Parrillo, J. E., Szabo, C.

Megjegyzések:To determine whether activation of the nuclear enzyme poly(adenosine 5'-diphosphate [ADP]-ribose) synthetase (PARS) contributes to mortality rate, myocardial dysfunction, and cardiovascular collapse in a porcine model of sepsis induced by implantation of an infected clot. DESIGN: Prospective, random animal study. SETTING: Research laboratory at Rush Presbyterian St. Luke's Medical Center. SUBJECTS: Twenty pigs were chronically instrumented with intracardiac transducers to measure left ventricular pressure, sonomicrometer crystals in the left ventricle to measure short axis diameter, an ultrasonic flow meter to measure cardiac output, and catheters in the pulmonary artery and aorta to measure blood pressures and collect samples. INTERVENTIONS: By using a randomized study design, we administered either the novel potent PARS inhibitor PJ34 (10 mg/kg for 1 hr, 2 mg x kg(-1) x hr(-1) for 96 hrs) or vehicle to pigs immediately before intraperitoneal implantation of Escherichia coli 0111.B4 (2.3 +/- 0.1 x 10(10) colony-forming units/kg)-laden fibrin clots to produce peritonitis and bacteremia. MEASUREMENTS AND MAIN RESULTS: In vehicle-treated pigs, 12% survival was recorded at 24 hrs, whereas 83% and 66% survival was recorded in the PJ34-treated animals at 24 and 96 hrs, respectively (p <.05). PJ34 treatment attenuated bacteremia-induced increases in systemic and pulmonary vascular resistances. In controls, peritonitis induced rapid increase in plasma tumor necrosis factor-alpha. PJ34 treatment significantly attenuated this cytokine response. The formation of peroxynitrite and the activation of PARS were confirmed in hearts and lungs of the septic pigs by the immunohistochemical detection of nitrotyrosine and poly(ADP-ribose), respectively. Inhibition of PARS with PJ34 abolished poly(ADP-ribose) formation in septic animals. CONCLUSIONS: Treatment with a potent PARS inhibitor improved survival and cardiovascular status and attenuated an important mediator component of the inflammatory response in a lethal porcine model of sepsis.

Cím:Novel phenanthridinone inhibitors of poly (adenosine 5'-diphosphate-ribose) synthetase: potent cytoprotective and antishock agents / Jagtap, P., Soriano, F.

Megjegyzések:To synthesize novel inhibitors of the nuclear enzyme poly(adenosine 5'-diphosphate [ADP]-ribose) synthetase (PARS), also known as poly(ADP-ribose) polymerase (PARP), and to test them in in vitro models of oxidant-induced cytotoxicity and in endotoxin and splanchnic occlusion-reperfusion-induced shock. DESIGN: Randomized, prospective laboratory study. SETTING: Research laboratory. SUBJECTS: Murine macrophages, thymocytes, and endothelial cells; Balb/c mice and Wistar rats. INTERVENTIONS: Macrophages and endothelial cells were treated with peroxynitrite and bleomycin to induce PARS activation, and thymocytes were treated with peroxynitrite to induce cell necrosis. Novel PARS inhibitors were synthesized and used to reduce PARS activation and to reverse cytotoxicity. Balb/c mice were subjected to splanchnic occlusion and reperfusion and were pretreated with various doses (1-10 mg/kg intraperitoneally) of PJ34, a selected, potent, water-soluble PARS inhibitor. The passage of fluorescein isothiocyanate-conjugated dextran (4 kDa) was analyzed in everted gut ileal sacs incubated ex vivo as an index of gut permeability. Wistar rats were subjected to Escherichia coli bacterial lipopolysaccharide (40 mg/kg intraperitoneally). PJ34 was also used at 10 mg/kg intraperitoneally, 1 hr before lipopolysaccharide or at 25 mg/kg intraperitoneally 1 hr after lipopolysaccharide treatment. Serum concentrations of indicators or multiple organ injury, concentrations of various proinflammatory mediators, and tissue concentrations of myeloperoxidase and malondialdehyde were measured. In addition, survival rates and vascular contractile and relaxant responses were recorded. MEASUREMENTS AND MAIN RESULTS: Appropriate modifications of the phenanthridinone core structure yielded significant increases in the potency of the compounds, both as PARS inhibitors and as cytoprotective agents. The compound N-(6-oxo-5,6-dihydro-phenanthridin-2-yl) -N,N-dimethylacetamide (designated as PJ34) was one of the potent PARS inhibitors of the series, and it dose-dependently protected against thymocyte necrosis, with a half-maximal restoration of cell viability of 35 nM and complete protection at 200 nM. PARS activation also was visualized by immunohistochemistry and was dose-dependently suppressed by PJ34. The effect of PJ34 was dose-dependently reversed by excess nicotinamide adenine dinucleotide (oxidized). The PARS inhibitors dose-dependently suppressed proinflammatory cytokine and chemokine production and restored viability in immunostimulated macrophages. PJ34 was selected for the subsequent in vivo studies. PJ34 significantly protected against splanchnic reperfusion-induced intestinal hyperpermeability in the mouse. PJ34 reduced peak plasma concentrations of tumor necrosis factor-alpha, interleukin-1beta, and nitrite/nitrate in the plasma of lipopolysaccharide-treated rats. PJ34 ameliorated the lipopolysaccharide-induced increases in indexes of liver and kidney failure and concentrations of myeloperoxidase and malondialdehyde in the lung and gut. Lipopolysaccharide elicited vascular dysfunction, which was normalized by PJ34. Lipopolysaccharide-induced mortality was reduced by PJ34 (both pre- and posttreatment). CONCLUSIONS: The novel series of phenanthridinone PARS inhibitors have potent cytoprotective effects in vitro and significant protective effects in shock and reperfusion injury in rodent models in vivo.

Dátum:2009
ISSN:1364-8535 1466-609X
Megjegyzések:There were no differences in the magnitude of the stapedius reflex during anesthesia when administering sounds at different frequencies, therefore the lowest frequency was used in the further analysis. The reflex was totally blocked during profound neuromuscular block, which was indicated by elevation of stapedius reflex threshold. When the TOF ratio was 0.9 or above this limit, the reflex recovered.

Dátum:2001
Megjegyzések:Patients with severe burn and/or smoke inhalation injury suffer both systemic and pulmonary vascular hyperpermeability. We hypothesized that nitric oxide (NO) produced by inducible nitric oxide synthase (iNOS) plays a role in the changes in microvascular permeability seen with this injury. To test the hypothesis, we administered mercaptoethylguanidine (MEG), a selective iNOS inhibitor, to conscious sheep subjected to a combined smoke inhalation and third-degree burn injury to 40% of total body surface area. The sheep were surgically prepared for chronic study with lung and prefemoral lymph fistulas in order to estimate microvascular permeability. Both the groups and a control group of animals showed an increase in iNOS protein and message in their lungs. The control animals showed significant increases in either plasma or lymph NO2-/NO3- (NOx) concentration at 24 h after injury, with associated cardiac depression and hemoconcentration. The airway epithelium stained for nitrotyrosine. In the treatment group, NOx did not increase significantly in plasma or lymph throughout the experiment, there was no nitrotyrosine staining, hemodynamic depression was not observed, and the fluid requirement was significantly less than in the control group. Changes in pulmonary microvascular permeability were significantly suppressed by inhibition of iNOS. However, there was no significant difference between the two study groups in the microvascular permeability of burned tissue. These data suggest that NO produced by iNOS plays an important role in the changes in systemic and pulmonary microvascular permeability in combined smoke inhalation/third-degree burn injury, but does not affect the vascular permeability of third-degree-burned tissue in this type of injury.
