Insights
This study found that abnormal mean corpuscular volume (MCV) values can effectively identify infants with normal iron stores. This simple screening method aids in early detection of iron status in infants.
Area of Science:
- Pediatric Hematology
- Nutritional Biochemistry
- Infant Health
Context:
- Iron deficiency is a prevalent global health issue in infants.
- Early identification of iron status is crucial for healthy development.
- Erythrocyte indices are commonly used in pediatric health assessments.
Purpose:
- To establish the correlation between erythrocyte indices and serum ferritin (SF) levels in infants.
- To identify reliable indicators for normal iron stores in infants aged eight months.
- To assess the diagnostic accuracy of mean corpuscular hemoglobin (MCH) and mean corpuscular volume (MCV) for iron status.
Summary:
- 112 infants were studied, categorized by serum ferritin levels into severe deficient (<12 ng/mL), moderate deficient (12-20 ng/mL), and normal iron stores.
- Abnormalities in MCH (40.1%), MCV (29.5%), and hemoglobin (Hb) (6.2%) were observed.
- Mean corpuscular volume (MCV) demonstrated high specificity (0.88, 0.92) in identifying infants with normal iron stores, especially when SF < 20 ng/mL. Simultaneous alterations in MCH and MCV also showed high specificity (0.92).
Impact:
- Abnormal MCV values, alone or with MCH, provide a high probability for identifying infants with normal iron stores.
- This research offers a potentially simple and effective method for screening infant iron status.
- Findings can inform public health strategies for preventing and managing iron deficiency in infants.
Abstract:
For establishment correlation between erythrocyte indices and serum ferritin (SF), to identify infants at eighth months of age, with iron normal corporal stores, were studied 112 infants; 40 cases had severe deficient iron stores (SF < 12 ng/mL), 17 cases with "moderate" deficient iron stores (SF 12-20 ng/mL) and 55 infants with normal iron stores. The mean corpuscular hemoglobin (MCH) was altered in the 40.1%, the mean corpuscular volume (MCV) 29.5% and hemoglobin (Hb) 6.2%. In severe deficient iron stores, the MCH, with abnormal values had minor specificity (0.62), that MCV (0.88). With a SF < 20 ng/mL, specificity of the MCV was 0.92. Simultaneous alteration on MCH and MCV had similar specificity (0.92) and predictive positive values. With abnormal values of CMH + MCV or MCV alone, were established high probability for identify infants with normal iron stores.

Erythropoiesis
Structure and Function of Erythrocytes
The erythrocyte plasma membrane is associated with proteins such as spectrin, which forms a flexible cytoplasmic meshwork. This meshwork allows erythrocytes to twist, turn, become cup-shaped, and regain their biconcave shape as they pass through narrow capillaries. Additionally, erythrocytes can form...
Lifecycle of Erythrocytes
The resident phagocytic macrophages deal with these damaged cells by engulfing them and separating their globin and heme groups.
Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...
Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
EPO then...
