Insights
Maternal vitamin B12 deficiency can cause severe anemia and developmental delay in exclusively breastfed infants. Early nutritional assessment and intervention are crucial to prevent irreversible neurological damage in infants.
Area of Science:
- Pediatrics
- Nutrition
- Hematology
Background:
- Nutritional vitamin B12 deficiency is rare in children, often linked to maternal insufficiency.
- Exclusively breastfed infants are particularly vulnerable to vitamin B12 deficiency due to maternal intake.
- Maternal B12 deficiency can lead to significant health issues in infants.
Observation:
- A case of a breastfed infant presenting with megaloblastic anemia due to maternal vitamin B12 deficiency.
- The infant exhibited severe pancytopenia and regression of motor functions.
- Developmental delay and regression were key presenting symptoms.
Findings:
- Maternal vitamin B12 deficiency can manifest as severe pancytopenia in infants.
- Neurological regression and developmental delay are significant potential consequences.
- The infant's condition was directly linked to the mother's nutritional status.
Implications:
- Highlights the importance of maternal nutritional history in infant health assessments.
- Emphasizes the need for early detection and management of vitamin B12 deficiency in breastfeeding mothers and infants.
- Underscores the potential for preventing severe, irreversible neurological damage through timely intervention.
Abstract:
Nutritional B12 deficiency in childhood is an uncommon disorder. Most cases are due to maternal insufficiency, resulting from deficient stores and intake, and is generally seen in exclusively breast fed infants. This report describes a breast-fed infant with megaloblastic anemia secondary to maternal vitamin B12 deficiency. We describe this patient to remind readers that B12 deficiency may cause severe pancytopenia and regression of motor functions. These patients can present with unexpected signs and symptoms, such as developmental delay and regression as in our patient. It is also important to take the nutritional history of both the child and the mother of early prevention and treatment. With early awareness and appropriate measures potentially irreversible neurologic damage can be prevented in the infant.

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.
