High-Folate-Low-Vitamin B12 Interaction Syndrome

Area of Science:

• Neurology
• Hematology
• Nutritional Science

Background:

• Vitamin B12 deficiency presents with diverse hematological and neurological issues, potentially leading to irreversible damage if untreated.
• The interaction between folic acid and vitamin B12 can complicate diagnosis and treatment.

Purpose of the Study:

• To report a case of vitamin B12 deficiency caused by excessive folic acid intake.
• To highlight the diagnostic challenges and clinical implications of the high-folate-low-vitamin B12 interaction.

Main Methods:

• Case report of a patient presenting with balance disorders and macrocytosis.
• Biochemical analysis revealing vitamin B12 deficiency and elevated folate levels.
• Review of the pathophysiological interaction between folic acid and vitamin B12.

Main Results:

• The patient exhibited symptoms consistent with vitamin B12 deficiency.
• Elevated serum folate levels in the presence of vitamin B12 deficiency suggested a high-folate-low-vitamin B12 interaction.
• This interaction was hypothesized as the cause of the patient's vitamin B12 depletion.

Conclusions:

• Neurological symptoms warrant testing for vitamin B12 deficiency, with concurrent folate level measurement.
• Early diagnosis and treatment are essential to prevent irreversible neurological deficits.
• The study underscores the importance of considering folate levels in vitamin B12 deficiency diagnosis, especially with prolonged folic acid supplementation.
