Insights

Leukocyte counts in dyslipidaemia patients correlate with LDL cholesterol levels and LDL oxidation. Monocyte-neutrophil interactions may serve as a prognostic factor for coronary heart disease (CHD).

Area of Science:

  • Cardiovascular Research
  • Immunology
  • Metabolic Disorders

Background:

  • Leukocyte counts are critical in inflammatory diseases like coronary heart disease (CHD).
  • Elevated leukocyte counts correlate with inflammation intensity and poor outcomes.
  • This study examines leukocyte subsets in dyslipidaemia and their link to LDL oxidation.

Purpose of the Study:

  • Investigate leukocyte and subset counts in dyslipidaemia patients.
  • Determine the relationship between leukocyte counts, LDL cholesterol (LDL-C), and LDL oxidation.
  • Explore the role of HNP-1 and myeloperoxidase in CHD and dyslipidaemia.

Main Methods:

  • Analyzed blood counts and LDL-C in 207 dyslipidaemia patients.
  • Compared HNP-1 and myeloperoxidase levels in leukocyte subsets between 24 CHD patients and 24 controls.
  • Assessed HNP-1 mRNA levels and myeloperoxidase distribution.

Main Results:

  • Total leukocyte and neutrophil counts increased with LDL-C (p=0.001); monocyte counts decreased (p=0.001).
  • Neutrophil HNP-1 mRNA levels were significantly higher in CHD patients (2.13-fold), while monocyte levels were lower (p=0.005).
  • Myeloperoxidase distribution differed between monocytes and neutrophils.

Conclusions:

  • Leukocyte counts and LDL-C levels may be linked to LDL oxidation.
  • Monocyte-neutrophil interactions suggest a compensatory mechanism in LDL oxidation in CHD.
  • These interactions could be a prognostic indicator for CHD.

Structure and Function of Leukocytes01:21

Structure and Function of Leukocytes

An adult in good health typically has between 4,500 and 11,000 leukocytes, or white blood cells, per microliter of blood, which constitutes about 1% of the total blood volume. Unlike red blood cells, white blood cells contain a nucleus and other cellular organelles but do not have hemoglobin. Most white blood cells reside in connective tissues, particularly in lymphatic organs such as the lymph nodes, with only a small fraction present in circulating blood.
White blood cells protect the body...
Disorders of Leukocytes01:27

Disorders of Leukocytes

Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
Classification of Leukocytes01:30

Classification of Leukocytes

Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...
Imbalances in Cardiac Output01:26

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send blood...
Differentiation of Common Myeloid Progenitor Cells01:15

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
