Summary
Serum soluble triggering receptor expressed on myeloid cells (sTREM)-1 shows poor prognostic utility in septic shock. Procalcitonin measurements are more effective for predicting outcomes in these critically ill patients.
Area of Science:
- Critical Care Medicine
- Immunology
- Biomarker Discovery
Background:
- The soluble triggering receptor expressed on myeloid cells (sTREM)-1 is a potential biomarker for sepsis diagnosis.
- Septic shock requires accurate prognostic markers for timely intervention and improved patient outcomes.
Purpose of the Study:
- To evaluate the prognostic value of serum sTREM-1 in patients with septic shock.
- To compare the prognostic utility of sTREM-1 with procalcitonin (PCT) in septic shock.
Main Methods:
- A study of 31 consecutive septic shock patients in a tertiary medical ICU.
- Measurement of serum sTREM-1, procalcitonin, and inflammatory cytokines (IL-1β, IL-6, IL-10, TNF-α) on days 1-3 of ICU admission.
- Correlation analysis with clinical severity scores (APACHE II, SOFA), vasopressor use, and bacteremia.
Main Results:
- No significant difference in sTREM-1 levels between survivors and non-survivors.
- sTREM-1 showed moderate correlation with APACHE II and SOFA scores on day 3, but not with other clinical parameters.
- Procalcitonin levels were significantly higher in non-survivors on days 2 and 3 and correlated with other variables.
Conclusions:
- Serum sTREM-1 demonstrates poor prognostic utility in septic shock.
- Procalcitonin is a more effective prognostic biomarker than sTREM-1 in septic shock patients.

01:20Blood Studies for Cardiovascular System I: Cardiac Biomarkers
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

01:19Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

01:24Serum Studies: Renal Function Tests
Renal function tests are crucial for assessing kidney health, monitoring disease progression, and evaluating the kidneys' efficiency in waste elimination, fluid balance, and electrolyte regulation. These tests offer critical insights into kidney function, even though routine measurements may appear normal until there is a significant decline in the glomerular filtration rate or GFR. Typically, signs of kidney impairment only become evident when the GFR falls to about 50% of its normal level.
