Insights

Serum soluble receptor for advanced glycation end-products (sRAGE) is significantly associated with COVID-19 severity. Higher sRAGE levels indicate a greater risk of severe illness, aiding in early detection of lung damage.

Area of Science:

  • Biomarkers and Disease Severity
  • Pulmonary Medicine
  • Infectious Diseases

Background:

  • Coronavirus disease 2019 (COVID-19) necessitates biomarkers for early tissue damage detection.
  • Soluble receptor for advanced glycation end-products (sRAGE) is a potential biomarker for early lung damage.

Purpose of the Study:

  • To analyze the association between serum sRAGE levels and COVID-19 severity.
  • To evaluate sRAGE as a potential indicator of lung damage in COVID-19 patients.

Main Methods:

  • Cross-sectional study with 145 participants (47 non-severe, 98 severe COVID-19 cases).
  • Analysis of serum sRAGE levels using statistical tests including chi-square, Fisher's exact, t-test, Mann Whitney, and Spearman's rank tests.
  • Evaluation of diagnostic performance with sensitivity, specificity, and AUC.

Main Results:

  • Significant differences in leukocytes, lymphocytes, neutrophils, procalcitonin, CRP, and D-dimer between severe and non-severe groups.
  • Significantly higher serum sRAGE levels in severe COVID-19 patients (1.47 ng/mL) compared to non-severe (0.78 ng/mL).
  • Strong positive association (r=0.598, p<0.001) between serum sRAGE and COVID-19 severity; cut-off value of 0.985 ng/mL with 73.5% sensitivity and 74.5% specificity.

Conclusions:

  • Serum sRAGE is significantly associated with COVID-19 severity.
  • Elevated serum sRAGE levels differentiate between severe and non-severe COVID-19 cases, suggesting its utility in assessing disease progression and lung damage.

Overview of Carbohydrate Metabolism01:19

Overview of Carbohydrate Metabolism

Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

Proteoglycans01:05

Proteoglycans

Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

Enzyme-Linked Immunosorbent Assay

In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen.  Enzyme-substrate reaction allows the antigen to be visualized or...

Oligosaccharide Assembly01:24

Oligosaccharide Assembly

Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.
Multiple sugar molecules that may or may...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...
