Study of erythrocyte shape changes in schistosomiasis

Area of Science:

• Hematology
• Parasitology
• Medical Imaging

Background:

• Schistosomiasis is a parasitic disease affecting millions globally.
• Erythrocyte (red blood cell) morphology can be affected by various pathological conditions.
• Understanding red cell changes in schistosomiasis is crucial for assessing disease impact.

Purpose of the Study:

• To investigate the specific red blood cell morphological alterations in patients with schistosomiasis.
• To correlate these morphological changes with the stage of liver disease and other clinical parameters.

Main Methods:

• Patients were categorized into three groups based on schistosomiasis disease stage.
• Evaluations included clinical examination, liver/renal function tests, complete blood count, and abdominal ultrasonography.
• Scanning electron microscopy (SEM) was used to analyze erythrocyte morphology.

Main Results:

• Significant abnormal red blood cell morphology was observed, including 70.14% flat discoid cells and 12.34% with margin changes.
• No statistical difference in red cell shape changes was found across different liver disease stages.
• A positive correlation existed between portal vein diameter and flat discoid red cells; a negative correlation was noted between surface changes and clinical liver disease stage.

Conclusions:

• Schistosomiasis induces distinct red blood cell morphological changes not previously reported in other diseases.
• These erythrocyte alterations are associated with reduced red cell deformability and impaired capillary blood flow.
• Red cell morphology in schistosomiasis shows specific correlations with ultrasonographic findings, independent of liver disease severity.
