ICD-10: E53.1

Pyridoxine deficiency, classified under ICD-10 code E53.1, refers to a condition resulting from insufficient levels of vitamin B6 (pyridoxine) in the body. This vitamin plays a crucial role in numerous physiological functions, including amino acid metabolism, neurotransmitter synthesis, and the production of hemoglobin. Below is a detailed clinical description and relevant information regarding this deficiency.

Clinical Description

Definition and Causes

Pyridoxine deficiency occurs when there is an inadequate intake or absorption of vitamin B6, which can lead to various health issues. Common causes include:

• Inadequate Dietary Intake: A diet lacking in vitamin B6-rich foods such as poultry, fish, potatoes, chickpeas, bananas, and fortified cereals can lead to deficiency.
• Malabsorption Syndromes: Conditions like celiac disease, Crohn's disease, or chronic pancreatitis can impair the absorption of nutrients, including vitamin B6.
• Increased Requirements: Certain populations, such as pregnant or lactating women, may have higher requirements for vitamin B6, increasing the risk of deficiency if not adequately met.
• Medications: Some medications, such as isoniazid (used for tuberculosis) and certain anticonvulsants, can interfere with vitamin B6 metabolism and lead to deficiency.

Symptoms

The clinical manifestations of pyridoxine deficiency can vary but often include:

• Dermatological Symptoms: Seborrheic dermatitis, cheilosis (cracks at the corners of the mouth), and glossitis (inflammation of the tongue).
• Neurological Symptoms: Peripheral neuropathy, characterized by numbness, tingling, or pain in the extremities, and seizures in severe cases.
• Hematological Symptoms: Microcytic anemia due to impaired hemoglobin synthesis, leading to fatigue and weakness.
• Psychological Symptoms: Depression, confusion, and irritability may also occur due to the role of vitamin B6 in neurotransmitter synthesis.

Diagnosis

Diagnosis of pyridoxine deficiency typically involves:

• Clinical Evaluation: Assessment of symptoms and dietary history.
• Laboratory Tests: Measurement of plasma pyridoxal phosphate (the active form of vitamin B6) can confirm deficiency. Normal levels are generally above 30 nmol/L, with levels below this indicating deficiency.

Treatment

The primary treatment for pyridoxine deficiency involves:

• Dietary Modification: Increasing the intake of vitamin B6-rich foods.
• Supplementation: Oral pyridoxine supplements are often prescribed, with dosages varying based on the severity of the deficiency and underlying causes. In severe cases, intramuscular injections may be necessary.
