About

Sepsis is the most common cause of death in the clinical critically ill patients. We have successfully screened the sepsis biomarkers by clinical proteomics approach and found that Vimentin (VIM) played an important role in the occurrence and development of sepsis. However, the exact mechanism is remaining unclear. In this study, the relationship between the changes of peripheral circulation VIM expression and different stages of sepsis development will be further verified in lager clinical trials, as well as the relationship between VIM expression and apoptosis of immune cells (e.g lymphocytes) will also be clarified. This may indicate that the role of VIM in the cell-mediated immunity apoptosis and inflammation-related pathways. Through the implementation of this study, we can clarify the clinical value of VIM and the mechanism of VIM-mediated immune cell apoptosis during the sepsis development from the molecular level, and determine whether the VIM as a new target for sepsis diagnosis and treatment.

Participants were excluded if they were younger than 18 years of age; contracted acquired immunodeficiency syndrome; had reduced polymorphonuclear granulocyte counts (<500 μL-1); died within 24 h after admission to the ICU; refused to participate in the study; or declined treatment during the period of observation.

Trial design

200 participants in 2 patient groups

sepsis

Description:

Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Organ dysfunction can be identified as an acute change in total SOFA score ≥2 points consequent to the infection. The baseline SOFA score can be assumed to be zero in patients not known to have preexisting organ dysfunction. ASOFA score ≥2 reflects an overall mortality risk of approximately 10% in a general hospital population with suspected infection. Even patients presenting with modest dysfunction can deteriorate further, emphasizing the seriousness of this condition and the need for prompt and appropriate intervention, if not already being instituted. In lay terms, sepsis is a life-threatening condition that arises when the body's response to an infection injures its own tissues and organs.

Treatment:

Diagnostic Test: VIM detection

septic shock

Description:

Patients with septic shock can be identified with a clinical construct of sepsis with persisting hypotension requiring vasopressors to maintain MAP ≥65 mm Hg and having a serum lactate level \>2 mmol/L (18mg/dL) despite adequate volume resuscitation.

Treatment:

Diagnostic Test: VIM detection
