Insights

C-reactive protein (CRP), presepsin (PSP), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) can predict prognosis in non-severe COVID-19 patients. No biomarkers reliably predicted outcomes in severe COVID-19 cases.

Area of Science:

  • Clinical Medicine
  • Infectious Diseases
  • Biomarkers

Background:

  • Coronavirus disease 2019 (COVID-19) poses a significant global health challenge.
  • Identifying reliable biomarkers for predicting disease progression is crucial for patient management.
  • Distinguishing between non-severe and severe COVID-19 cases aids in therapeutic strategies.

Purpose of the Study:

  • To identify laboratory biomarkers that predict deterioration in COVID-19 patients.
  • To evaluate the prognostic value of various biomarkers in different COVID-19 severity groups.
  • To determine predictors of improvement versus deterioration in non-severe COVID-19.

Main Methods:

  • A cohort of 201 COVID-19 patients was classified into non-severe (n=125) and severe (n=76) groups.
  • Laboratory biomarker levels (including Neutrophil count, AST, LDH, CRP, KL-6, PCT, PSP, D-dimer, lymphocyte, and platelet counts) were analyzed.
  • Receiver operating characteristic (ROC) analysis and multivariate analysis were employed to assess biomarker utility.

Main Results:

  • Neutrophil count, AST, LDH, CRP, KL-6, PCT, PSP, and D-dimer were elevated in the non-severe group compared to the severe group.
  • Lymphocyte and platelet counts were lower in the non-severe group versus the severe group.
  • In non-severe cases, CRP, PSP, AST, and LDH were identified as useful predictors of prognosis via ROC analysis. CRP was a significant independent prognostic factor (OR, 41.45; P<0.001). No biomarkers predicted outcomes in severe cases.

Conclusions:

  • Several blood markers significantly correlate with COVID-19 disease severity.
  • CRP, PSP, LDH, and AST are reliable prognostic markers for non-severe COVID-19 patients.
  • No specific blood biomarkers were found to predict outcomes in patients with severe COVID-19.

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:

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...

Sensitivity, Specificity, and Predicted Value

In healthcare diagnostics, laboratory tests play a crucial role in identifying and diagnosing a wide range of medical conditions. However, interpreting test results is not always straightforward. An abnormal test result does not always confirm the presence of a disease, just as a normal result does not guarantee its absence. To assess the reliability of these diagnostic tools, healthcare practitioners rely on two key statistical indicators: sensitivity and specificity.
Sensitivity is the...
