May biscuits contribute to iron balance? An observation in children with juvenile idiopatic arthritis.

Within an observational open study on the effects of a scheduled dosage of biscuits with iron, children with juvenile idiopathic arthritis were either supplemented with biscuits supplying iron fumarate (median 3.6 mg per day) or left to their customary dietary habits. After 4 months, supplemented children showed a more favourable percentage change of blood haemoglobin, while ferritin levels (markers of inflammation) remained stable. We conclude that the supply of iron with available dietary products may contribute to an adequate iron status in children with chronic inflammatory disorders in a stable situation.
