SIRS | Urinary Proteomics Analysis for Sepsis and Prognosis
SIRS research study
What is the primary objective of this study?
As a noninvasive examination, urinary proteomics is a very useful tool to identify renal disease. The purpose of the present study was to find differential proteins among patient with SIRS and sepsis(included survivors and non-survivors), and to screen potential biomarkers for the early diagnosis of sepsis and its prognosis. Urinary proteins were identified by iTRAQ labeling and LC-MS/MS. The bioinformatics analysis was performed with the Mascot software and the International Protein Index (IPI) and the Gene Ontology (GO) Database and KEGG pathway Database. The differentially expressed proteins were verified by Western blot by another sample collected from clinical.
Who is eligible to participate?
Inclusion Criteria: - Male and female aged 18 years old and over; - clinically confirmed infection; - fulfilled at least two criteria of systemic inflammatory response syndrome - (a) core temperature higher than 38 °C or lower than 36 °C - (b)respiratory rate above 20/min, or PCO2 below 32 mmHg - (c) pulse rate above 90/min, and - (d) white blood cell count greater than 12,000/μl or lower than < 4,000/μl or less than 10% of bands. Exclusion Criteria: - younger than 18 years of age; - acquired immunodeficiency syndrome; - reduced polymorphonuclear granulocyte counts (< 500 μL-1); - died within 24h after admission into the ICU, or refused to participate in the study, or declined treatment during the period of observation.
Which medical condition, disease, disorder, syndrome, illness, or injury is researched?
Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.
Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
SIRStemperature >38 ℃ or <36℃; pulse rate>90 beats/min; ventilatory rate>20 breaths/min or hyperventilation with partial pressure of arterial carbon dioxide (PaCO2)<32mmHg; white blood cell count>12,000μL-1 or <4000μL-1 or >10% immature cells
sepsisSepsis sepsis: SIRS plus infection; severe sepsis: sepsis associated with organ dysfunction, hypoperfusion, or hypotension; septic shock: sepsis with arterial hypotension, despite adequate ﬂuid resuscitation.
