Explain the causes, clinical features and treatment of Vitamin A deficiency.

The causes of Vitamin A deficiency

Vitamin A deficiency can result from inadequate intake, fat malabsorption, or liver disorders. Deficiency impairs immunity and hematopoiesis and causes rashes and typical ocular effects (eg, xerophthalmia, night blindness). Diagnosis is based on typical ocular findings and low vitamin A levels

Treatment of Vitamin A Deficiency

Vitamin A palmitate

Dietary deficiency of vitamin A is traditionally treated with vitamin A palmitate in oil 60,000 units orally once a day for 2 days, followed by 4500 units orally once a day. If vomiting or malabsorption is present or xerophthalmia is probable, a dose of 50,000 units for infants < 6 months, 100,000 units for infants 6 to 12 months, or 200,000 units for children > 12 months and adults should be given for 2 days, with a third dose at least 2 weeks later. The same doses are recommended for infants and children with complicated measles.
