Variations of erythrocyte morphology in different pathologies

Area of Science:

• Hematology
• Cell Biology
• Pathophysiology

Background:

• Erythrocytic morphology can be altered by various pathological conditions.
• Understanding red blood cell (RBC) shape changes is crucial for diagnosing and managing diseases.
• The Zipursky methodology offers a 3D evaluation of RBC morphology.

Purpose of the Study:

• To evaluate erythrocytic morphology in patients with vascular diseases, diabetes, liver disease, monoclonal gammopathies, and dehydration.
• To classify RBC shapes using a 3D evaluation method.
• To correlate RBC morphological alterations with specific pathologies.

Main Methods:

• Studied 150 subjects including normal controls and patients with various diseases.
• Employed the Zipursky methodology for a three-dimensional evaluation of red blood cells.
• Classified RBC shapes observed via optical microscopy.

Main Results:

• Normal subjects showed a higher percentage of bowls (55%) compared to discocytes (44%).
• Vascular patients exhibited a statistically significant increase in discocytes (60%).
• Diabetics with vascular disease had more discocytes (57%) and altered forms (3%); chronic hepatitis patients showed increased echinocytes and knizocytes (13%).

Conclusions:

• RBC morphology evaluation is a simple yet effective method for identifying pathological alterations.
• Specific RBC shape changes correlate with vascular diseases, diabetes, and liver conditions.
• Morphological alterations suggest impacts on RBC deformability and membrane fluidity, linked to metabolism and disease.
