Insights

Leukocyte cell population data (CPD) showed increased cell activation in early COVID-19 waves, indicating worse clinical conditions. These hematological parameters can serve as valuable disease markers for risk assessment.

Area of Science:

  • Hematology
  • COVID-19 Research
  • Clinical Diagnostics

Background:

  • Hematological parameters are crucial in understanding COVID-19.
  • Leukocyte cell population data (CPD) is being explored for its clinical significance.
  • Previous studies highlighted the importance of hematological parameters during the COVID-19 pandemic.

Purpose of the Study:

  • To assess cell population data (CPD) in SARS-CoV-2 patients.
  • To evaluate CPDs as potential novel disease markers for COVID-19.
  • To compare CPDs between different waves of the COVID-19 pandemic.

Main Methods:

  • Enrolled 540 patients in the 1st wave (Feb-Apr 2020) and 2821 in the 2nd wave (Sep-Dec 2020).
  • Diagnosed SARS-CoV-2 using Multiplex rRT-PCR.
  • Analyzed CPDs with a Sysmex XN 2000 hematology analyzer and measured C-reactive protein (CRP) and lactate dehydrogenase (LDH).

Main Results:

  • Observed increased CPDs across all cell types in both waves compared to reference populations.
  • Found 9 CPDs elevated in the 1st wave versus 5 in the 2nd wave.
  • Noted significantly higher CPD values (NE-SFL, LY-Y, LY-Z, MO-X, MO-Y), CRP, and LDH in the 1st wave compared to the 2nd wave.

Conclusions:

  • CPDs indicated heightened cell activation in 1st wave patients, correlating with worse clinical outcomes.
  • CPDs serve as effective markers for disease characterization in COVID-19.
  • CPDs show potential utility in developing risk models for COVID-19 patients.

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...

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...

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...
