Blood pressure was maintained for 90 min and constantly monitored during bleeding by a measuring cell (FMI TBD-1222, Föhr Medical Instruments GmbH, Seeheim, Germany) and a measuring amplifier (MIO-0501 DC, Föhr Medical Instruments GmbH). In the meantime, to ensure continued support, we are displaying the site without styles Plasma was isolated from blood samples after centrifugation at 2500×g for five minutes at room temperature (Eppendorf 3200, Hamburg, Germany) and then stored at − 80 °C for later analyses of IL-6, IL-1 β, SAA1 and CXCL1 using the specific Mouse DuoSet ELISA Kits of R&D Systems according to the manufacturer’s instructions (Wiesbaden-Nordenstadt, Germany). Taken together, there is a good concurrence in the data of those and other studies. Anesthesia was administered by inhalational isoflurane (Baxter Deutschland GmbH, Unterschleißheim, Germany) vaporization and 1% prilocainhydrochlorid (Xylonest, AstraZeneca GmbH, Wedel, Germany) was used for local anesthesia.

In our recent experimental study, we confirmed a significant mortality after hemorrhagic shock but as well after multiple trauma with shock30,51. https://doi.org/10.1111/j.1476-5381.2011.01595.x (2012). Our data demonstrate that mean tPA and PAI-1 antigen levels significantly increased after polytrauma. ISSN 2045-2322 (online). Thromb Haemost. TxT group had a significantly increased Il-6 gene expression in the lung compared to Fx, Lap and bsTT groups (p < 0.05, Fig. Google Scholar. Furthermore, the strong positive correlation between tPA and PAI-1 antigen levels within the first week post-trauma indicates that tPA and PAI-1 synthesis and their clearance from circulation [by hepatic cells (35)] might be biologically linked. Dies kann unter anderem zu folgenden Konsequenzen und Komplikationen führen: Um die Rhesus-Sensibilisierung zu vermeiden, erhalten alle Frauen, die Rh-positiv sind, eine Rhesus-Prophylaxe mit Anti-D-Immunglobulin. https://doi.org/10.1007/978-1-4939-7526-6_1 (2018). After vascular injury, a rapid, short-term release of tPA occurs within minutes (12). However, the infiltration with inflammatory cells among the monotrauma groups was highest in HS and TxT groups, while this trend to increased infiltration was not significant compared to control groups (data not shown). Error variances were modeled as heterogeneous between different time points. Res. Inflammatory and apoptotic alterations in serum and injured tissue after experimental polytrauma in mice: distinct early response compared with single trauma or “double-hit” injury. 2d). Regarding ARDS, mean tPA antigen levels were higher in individuals suffering from this syndrome than in those without ARDS during the entire observation period. Google Scholar. IL-10) mediators were experimentally and clinically demonstrated to play important roles in this damage response to traumatic injury, or to indicate outcomes6,7,40,41. Although these levels presented fluctuations, they remained elevated for at least 3 weeks. 74, 792–800. and K.K. Uteruskontraktionen können auch schon vor den Wehen auftreten. Consequently, the question about the suitability of the used multiple injury models to represent the clinical situation are currently under discussion9,11,12,13,14. The exact pathophysiological reasons for the enhanced organ injury in liver and lung in the blunt chest trauma model, hemorrhagic shock model, as well as in all three models of multiple trauma are rather speculative, however, they are concurrent with evident increase in proinflammatory cytokines and infiltration with inflammatory cells.

Mikkelsen ME, Christie JD, Lanken PN, Biester RC, Thompson BT, Bellamy SL, et al. For the determination of the IL-6, IL-10 and HMGB1 expression in liver and lungs, paraffin-embedded sections were deparaffinized, rehydrated, and stained with antibodies as described earlier21. Mira, J. C. et al. Increasing overhead ressources of the trauma room. Its pathogenesis is complex, and its development is difficult to anticipate, as candidate biomarkers for the prediction of ARDS were found not to be reliable for clinical use. Contributing factors in the development of acute lung injury in a murine double hit model. For biomarker analyses, we employed Luminex multianalyte technology. Different experimental multiple trauma models induce comparable inflammation and organ injury, https://doi.org/10.1038/s41598-020-76499-z. Emerg. Though, the choice of read-out parameters is very important for therapeutic immune modulatory approaches. 201508440220 received by BY. The procoagulant molecule plasminogen activator inhibitor-1 is associated with injury severity and shock in patients with and without traumatic brain injury. 4a). Med. Butcher, N. & Balogh, Z. J. AIS>2 in at least two body regions: a potential new anatomical definition of polytrauma. doi: 10.1055/s-0038-1646441, 29. Early immunologic response in multiply injured patients with orthopaedic injuries is associated with organ dysfunction. In this study, as well as in the previous one30, blunt thoracic trauma was assigned an AIS of 3, which is equivalent to a serious chest trauma with unilateral lung contusion and a rib series fracture57. Also considering the first 2 weeks after the trauma occurred, each pair of tPA antigen levels was significantly correlated, whereas no correlations were found for the tPA antigen levels at day 21. The injury severity was calculated as described before29,30,31 in all multiple trauma groups according to the ISS system. p < 0.05 vs. indicated or * vs. Ctrl; # vs. Sham; a vs. PT I; b vs. PT II; c vs. MT. Polytrauma und Schwangerschaft: spezifische Verletzungen bei schwangeren Frauen As described before laparotomy (Lap) was performed in a supine position30. It focuses on five different topics, 1. to polytrauma). (Center for Medical Statistics, Informatics and Intelligent Systems, Medical University of Vienna) for his assistance with statistics. High levels of tissue plasminogen activator (tPA) antigen precede the development of type 2 diabetes in a longitudinal population study. Relja, B., Yang, B., Bundkirchen, K. et al. (30). Clinical parameters at admission. 1 ml of preheated 0.9% sodium chloride solution was provided into the cavity. p < 0.05 vs. indicated or * vs. Ctrl; # vs. Sham; a vs. PT I; b vs. PT II; c vs. MT. Chest. Natl. Infiltration of inflammatory cells into lung and liver was significant in all multiple trauma groups vs. controls. According to our findings, the increase of serum tPA antigen levels in polytrauma victims after admission should be considered as a warning sign of ARDS development, indicating the potential of plasma tPA antigen, when repeatedly assessed, as a reliable biomarker to identify polytraumatized patients at high risk of developing this syndrome. García-Laorden MI, Lorente JA, Flores C, Slutsky AS, Villar J. Biomarkers for the acute respiratory distress syndrome: how to make the diagnosis more precise. Methods Local fibrinolysis. While the early mortality after trauma is mainly caused by massive blood loss, traumatic brain injuries or a non-controllable organ damage, later occurring mortality is mainly caused by secondary complications leading to (multiple) organ failure or multiple organ dysfunction syndrome (MODS)7,31. First, antigen retrieval was performed using R-universal solution (Aptum Biologics) under steam atmosphere for 20 min (Retriever 2010) and then, hydrogen peroxide was applied for blocking the endogenous peroxidase activity (Peroxidase UltraVision Block). Surg. The left liver lobe was ligated, removed, snap-frozen in liquid nitrogen and stored at − 80 °C until further analyses. Genomic responses in mouse models poorly mimic human inflammatory diseases. 6a). Our prospective study enrolled 28 consecutive blunt polytrauma survivors, who were directly admitted to our level I trauma center within 1 year and transferred to the intensive care unit after initial treatment.

Epidemiological data from 2016 to 2018 of the DGU Trauma Registry show that 81% of traumatized patients suffer from serious injuries. Transpl. Several attempts to develop multiple trauma models mimicking the complex post-injury situation in severely injured (polytraumatized) patients have been undertaken. Fibrinolysis and the control of blood coagulation. 4a). Interestingly, the time point of surgery had no impact on the curve progression of individual tPA antigen levels. The polytrauma provoked an instant, sharp increase in the mean tPA antigen level, and the levels at day 0, assessed immediately after admission, were >3-fold higher than the mean tPA antigen level of the healthy control group (1343 [338–2204] pg/mL). doi: 10.1111/jcmm.14671, Keywords: acute respiratory distress syndrome, ARDS, biomarker, fibrinolysis, plasminogen activator inhibitor type-1, pneumonia, polytraumatized patients, tissue plasminogen activator, Citation: Negrin LL, Dedeyan M, Plesser S and Hajdu S (2020) Impact of Polytrauma and Acute Respiratory Distress Syndrome on Markers of Fibrinolysis: A Prospective Pilot Study. After decreasing by 36% from day 0 to day 3 (p = 0.004), the mean tPA antigen level basically remained stable for up to 21 days (included). The model included time as categorical predictor as well as group and the interaction between time and group. This in turn contributed significantly to the injury of epithelial cells with subsequent capillary breakdown and microcirculatory disturbances42,43,44,45,46. Int. Med. J.

For this purpose the posttraumatic inflammatory response was evaluated in order to provide more information about a highly standardized and reproducible model which reflects the clinical situation in severely injured trauma patients. At six hours after trauma, systemic IL-6 levels were significantly increased in all trauma groups compared to Ctrl or Sham, respectively (p < 0.05, Fig. 5a). J. Orthopaed. The term “polytraumatism” used in practice is not exactly a synonym of polytrauma, however, it has a direct generalizing relation to it. Biol. https://doi.org/10.1073/pnas.1401965111 (2015).

In an effort to better replicate the human trauma, Gentile et al. After severe trauma, DAMPs typically induce a hyperinflammatory reaction mediated by chemokines and cytokines which is interlinked with a tenacious compensatory antiinflammatory response syndrome (CARS) leading to immunological suppression following trauma31,36,37,38,39. TBI frequently occurs in polytrauma in combination with other disabling conditions, such as amputation, burns, spinal cord injury, auditory and visual damage , spinal cord injury (SCI), post-traumatic stress disorder (PTSD), and other medical conditions. Cite this article. 2e). In line with our recent findings, we have shown that the experimental severe trauma model with a lower ISS has provided comparable results to both polytrauma models with higher ISS. Kaiser, K. et al.

Six hours after intervention, the animals were euthanized for sampling. 1717, 1–15. showing that their model produces an equivalent ISS associated with adverse outcomes in humans, and may better recapitulate the human leukocyte, cytokine, transcriptomic, and overall inflammatory response after polytrauma9,27. The management of polytrauma patients with orthopaedic injuries is a complex and dynamic process that requires a robust understanding of the pathophysiology of the response to trauma and indicators of patient status. Summary Successful identification, resuscitation, and treatment of patients with multiple trauma require a careful systematic and thorough approach. Among all monotrauma as well as multiple trauma groups the neutrophilic infiltration into the liver significantly increased compared to the Ctrl group (p < 0.05, Fig. The quantity and quality of RNA were determined using the NanoDrop ND-1000 device (Nano Drop Technologies, Wilmington, USA).

Moreover, changes in trauma mechanism over time and differences between continents were analyzed. 74, 489–498. Pfeifer, R., Tarkin, I. S., Rocos, B. The aim of this study was to compare demographics, injury patterns, injury mechanisms and outcomes between younger and older polytrauma patients. Thus, further increasing of the ISS may not necessarily lead to a superior model that would better represent the human trauma situation. And although several preclinical models have provided promising results, efforts at interventional strategies in clinical reality failed8,9,10. All authors read and approved the final manuscript. Nach einem Trauma kommt es häufiger vor, dass fetales Blut auf die Mutter übertragen wird. 1b). Biol. doi: 10.1161/ATVBAHA.111.230631, 27. Konkle BA, Schick PK, He X, Liu RJ, Mazur EM. 13. Relja, B., Mors, K. & Marzi, I. 24(6), 1178–85 (2006). The most common in vivo trauma models combine mainly two insults to better imitate the human conditions9,21,22,23,24,25,26. The inflammatory response and organ damage were quantified at 6 h by analyses of IL-6, IL-1β, IL-10, CXCL1, SAA1, HMGB1 and organ injury. Polytrauma and traumatic brain injury (TBI) frequently co-occur and outcomes are routinely measured by the Glasgow Outcome Scale-Extended (GOSE). New Injury Severity Score (NISS) takes three highest scores regardless of anatomic area. doi: 10.1161/01.CIR.96.3.761, 36. The Pearson correlation coefficient r was calculated to test the association between selected parameters. Care Med. 2b). A couple of experimental trauma models combining different injury severities were designed over the last decades to investigate the posttraumatic immune response after multiple trauma9,27,28,29,30. With regard to the clinical situation, a systemic inflammation caused by severe injuries is characteristic for the pathophysiological development of traumatized patients in the intensive care units. A variety of cellular and molecular mechanisms contribute to the complex pathophysiology of ARDS, including inflammation-induced coagulation and reduced fibrinolysis (7), which favor excessive intraalveolar fibrin deposition (8). Among the monotrauma groups, the TxT group had a significantly enhanced pulmonary HMGB1 expression compared to the Fx group (p < 0.05, data not shown). http://dx.doi.org/10.4321/S1695-61412012000100026. Immediately after sampling, blood was centrifuged at 3 000 × g for 15 min at room temperature, and serum was collected and stored at −80°C until assayed. Distinct molecular phenotypes of direct vs indirect ARDS in single-center and multicenter studies. If included in routine, daily blood sampling and analysis, the assessment of tPA antigen levels would not result in significant additional work and expenses. No significant differences with regard to the Hmgb1 gene expression in the lung were observed among the groups (Fig. Surg. Dadurch werden andere Organe weniger geschädigt. The clinical parameters assessed in our study group are displayed in Table 2. 19, 327–341. Contrarily, correlation coefficients between PAI-1 antigen levels were significant only in some cases, which might be explained by its regulated secretion from platelets caused by post-trauma triggers, as they vary between individuals. & Neunaber, C. Traumatic injury pattern is of equal relevance as injury severity for experimental (poly)trauma modeling. Moreover, we could not compare the study group and the healthy control group by means of variance analysis, as we did not sample blood from the healthy controls at the specified time points. CAS  3a), while the increase in CXCL1 protein expression in the Fx group was significant compared to the Ctrl (p < 0.05, Fig. Casasnovas C, Ruiz M, Schlüter A, Naudí A, Fourcade S, Veciana M, et al. Polytrauma is a major cause of mortality and morbidity in both developed and developing countries. The infiltration with inflammatory cells in the lung was significantly increased in all three multiple trauma groups compared to Ctrl and Sham groups (p < 0.05, data not shown). Weckbach, S. et al. (2006) 27:337–49. PLoS ONE 13, e0190587. Article  Am J Respir Cell Mol Biol. When the level of active PAI-1 increases in plasma, more active tPA is inhibited, leading to a lower level of active tPA and higher level of the tPA/PAI-1 complex.
