要旨

Background:

Sepsis is a state of life-threatening organ dysfunction caused by a dysregulated host response to infection, leading to consecutive organ failure and lethal outcome. The purpose of this study is to assess the value of the combined use of plasma high-density lipoprotein 2b (HDL2b) level and Sequential Organ Failure Assessment (SOFA) score in predicting short-term mortality from sepsis.

Materials And Methods:

A prospective, observational study was conducted in patients with sepsis and non-septic controls admitted to three intensive care units (ICUs) from January 2020 to December 2021. SOFA scores were recorded on the first day after admission. Blood samples were collected from each enrolled patient and the levels of HDL2b were analyzed using microfluidic chip technology. Receiver-operator characteristic curve (ROC) analyses were conducted to determine the values of plasma HDL2b level, SOFA score and the combined HDL2b levels and SOFA score (HDL2b + SOFA) in predicting the prognosis of mortality, respectively. The primary endpoint was 28-day mortality and the secondary outcome was total in-hospital mortality.

Results:

Compared to non-septic controls, patients with sepsis had lower HDL2b levels (10.95% [8.95, 12.96] vs. 23.78% [14.53, 29.16], p < 0.001). Among sepsis patients, the levels of HDL2b of non-survivors were lower than those of survivors (6.74% [4.63, 8.08] vs. 11.78 [7.20, 13.40], p = 0.002). Moreover, our data also indicated that patients with higher HDL2b + SOFA scores shown higher rates of 28-day and total in-hospital mortality. The areas under the ROC curves for predicting 28-day mortality were 0.755 for HDL2b, 0.782 for SOFA, and 0.806 for HDL2b + SOFA. Multivariate analyses indicated that HDL2b + SOFA (Odd Ratio: 1.321 (95% Confidence Interval: 1.028-1.698), p = 0.029) was potential predictors of 28-day mortality.

Conclusions:

The HDL2b + SOFA composite score was a reliable predictor of 28-day and in-hospital mortality in sepsis patients, showing better discriminatory ability than SOFA alone.

Blood 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...

Blood 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...
