Red blood cell distribution width index in some hematologic diseases.

Area of Science:

• Hematology
• Clinical Pathology

Background:

• Red blood cell distribution width (RDW) is a measure of the variation in red blood cell size.
• Anemia encompasses a range of conditions affecting red blood cells.
• RDW's utility in differentiating types of anemia requires further investigation.

Purpose of the Study:

• To evaluate red blood cell distribution width (RDW) in anemic male patients compared to normal male blood donors.
• To determine the correlation between RDW and reticulocyte count in various anemic conditions.

Main Methods:

• RDW was measured in anemic male patients and healthy male blood donors.
• RDW values were analyzed in relation to specific diagnoses, including sickle cell anemia, thalassemia, and iron deficiency.
• RDW was compared with reticulocyte counts.

Main Results:

• Anemic patients exhibited higher mean RDW values than normal controls (mean RDW for normal males: 11.3).
• RDW values were highest in sickle cell anemia, followed by sickle cell-beta thalassemia, sickle cell trait, beta-thalassemia trait, and iron deficiency.
• A positive correlation was observed between RDW and reticulocyte count, with sickle cell anemia showing the highest values.

Conclusions:

• Elevated RDW is indicative of anemia and its severity.
• RDW may serve as a useful indicator of active erythropoiesis.
• High RDW in patients with normal hemoglobin levels could suggest underlying hemoglobinopathies like sickle cell or thalassemia trait.
