Trauma Research Center Milestones


 

MILESTONES IN THE INJURY INVESTIGATIONS FROM OUR DENVER LABORATORIES

 1990       Sublethal endotoxin or IL-1 induce cardiac reprogramming/preconditioning by enhancing endogenous defenses. [1, 2]
 1991

In trauma patients, human portal blood is sterile and contains no endotoxin. [3]
Early enteral is superior to parenteral alimentation in the injured patient. [4, 5]

 1992 TWO HIT HYPOTHESIS: Post-injury systemic inflammation predisposes cells/organs to an altered response (protected or vulnerable) to a second stress. [6-8]
 
 1993

Post-injury alpha-adrenergic agonists reprogram ("precondition") cells to tolerate subsequent insult. [9]
Age, Injury Severity Score, 6 Units PRBC/12 hours, base deficit and lactate levels are early independent predictors of multiple organ failure (MOF). [10]

 1994 Phospholipase A2 (PLA2) is proximal mediator of disseminated injury after trauma. [11, 12]
 
 1995

The six isomers of protein kinase C in the human heart create a signaling language that dictates a cell's response to a subsequent insult. [13, 14]
Major torso trauma (first hit) primes and activates PMNs within 6 hours after injury leading to an early window during which a second hit activates exuberant PMN O2- release, rendering the injured patient at high risk for MOF. [15]

 1996

MOF presents in two patterns, early versus late, that have unique risk factors and clinical course. [16]
Neutrophils are critical in LPS induced acute lung injury and pulmonary vasomotor dysfunction.
[17]
Post-traumatic mediators delay neutrophil apoptosis. [18-20]

 
 1997 Oral sulfonylurea (oral hypoglycemic) agents block cardiac KATP channels, prevent myocardial preconditioning and explain the paradoxical increased cardiovascular mortality in diabetic patients on oral agents when compared to insulin. [21]
 1998

Metabolic therapy attenuates post-ischemic mitochondrial dysfunction. [22]
Plasma and lipids from stored blood cause acute lung injury.
[23, 24]
Soluble PLA2 is released into the systemic circulation following femoral fracture in patients. [25]
 

 1999

Liposome delivery of proteins such as I-kB and Hsp 72 to cells and tissues can be used to therapeutically manipulate inflammatory signal transduction. [26, 27]
Hemorrhagic shock releases factors into the mesenteric lymph not the portal circulation that prime neutrophils. [28]
 

 2000

IL-18 is preformed cytokine that primes neutrophil NADPH oxidase and contributes to ischemic myocardial injury and endotoxin mediated tissue injury. [29-31]
 

 2002

Neutrophils contain a membrane M-type sPLA(2)-R that activates p38 MAPK. [32]
The injured child is resistant to multiple organ failure.
[33]
Neutrophil mediated endothelial cell damage is dependent on endothelial activation, chemokine release, PMN adhesion, and lysophosphatidylcholines activation of the oxidase. [34]
 

 2003

Transfusion related acute lung injury (TRALI), like the acute respiratory distress syndrome, may be a 2-event phenomenon with both recipient predisposition and factors in the stored units playing major roles. [35] The importance of these results is highlighted by the fact that the FDA posted these results in a webcast.
Platelet-induced TRALI may be the result of two events: 1) the clinical condition of the patient and 2) the infusion of lipids in stored PLTs. [36]
 

 2005

Review of the Trauma database (1,344) trauma patients at risk for postinjury MO) shows that Lung dysfunction occurs in 94% patients with 1 or more organ dysfunctions and 99% of 605 patients with 2 or more organ dysfunctions. Lung dysfunction precedes heart, liver, and kidney dysfunction by 0.6, 4.8 and 5.5 +/- 0.5 days. [37]
The incidence, severity, and attendant mortality of postinjury MOF has decreased over the last 12 years despite an increased MOF risk. Improvements in MOF outcomes can be attributed to improvements in trauma and critical care and are associated with decreased use of blood transfusion during resuscitation.
[38]
Two different etiologies of TRALI are  proposed. The first is a single antibody-mediated event involving the transfusion of anti-HLA class I and class II antibodies into patients whose leukocytes express the cognate antigens. The second is a 2-event model. [39]
 

 2006

CHC is required for certain TNF-alpha-induced, inflammatory signaling pathways.  RNAi of clathrin significantly impairs phosphorylation of both I kappaB alpha and p65. [40]
PAF signaling in neutrophils involves clathrin mediated endocytosis, beta-arrestin-1 recruitment of a p38 MAPK signalosome, and actin bundle formation.
[41]
Initiated a US multicenter prehospital trial in which severely injured patients with major blood loss are resuscitated with stored RBCs whereas the study group receives HBOC (up to 6 units) in the first 12 hours.
[42]
HMGB1 can interact with both TLR2 and TLR4. [43]
 

 2007

Post shock mesenteric lymph is depleted of gelsolin and can activate NF-kB in endothelial cells. [44, 45]
Military-civilian collaboration in trauma care.
[46]
Nucleo-cytoplasmic traffic of NF-kB and I-kB. [47]
 

 2008

Splanchnic ischemia/reperfusion activates gut PLA(2)-mediated release of AA into the lymph where it is delivered to the lungs, provoking LTB(4) production and subsequent PMN-mediated lung injury. [48]
1:1 FFP:RBC reduces coagulopathy, but may increase mortality.
[49]
PAF involves clathrin mediated endocytosis induces membrane translocation of p40(phox)-p67(phox) localizing to gp91(phox).
[50]
HMGB1 release is an early event following traumatic injury in humans.
[51]
HMGB1 acquires proinflammatory activity through binding to proinflammatory mediators, such as IL-1beta. [52]
 

 2009

Packed red blood cell supernates induce T(regs), but this induction is not altered by leukoreduction or prolonged storage. [53]
PAF priming of PMNs requires clathrin-mediated endocytosis that is inhibited when PMNs are pretreated with either amantadine or rimantadine.
[54]
Patients resuscitated with PolyHeme, without stored blood for up to 6 U in 12 hours postinjury, had outcomes comparable with those for the standard of care. Although there were more adverse events in the PolyHeme group, the benefit-to-risk ratio of PolyHeme is favorable when blood is needed but not available.
[55]
Hypertonic saline inhibits TNFa-induced NF-kB activation in pulmonary epithelial cells.  [56]
