Diet for the Non-Transfused Patient
Non-transfused thalassemia intermedia patients are
encouraged to avoid high-iron and iron-supplemented foods, and encouraged
to drink tea with meals, which decreases iron absorption. Serum ferritin
is evaluated in adolescents. Desferrioxamine is instituted early in the
development of hemosiderosis. Iron overloaded individuals receive a liver
biopsy. Early cardiac evaluation with Holter monitoring and stress ECHO
cardiogram is done in individuals with significant hemosiderosis. In addition,
folic acid deficiency appears to be more common in these individuals.
Low Iron Diet for the Chronically-Transfused Patient
Regular blood transfusions can lead to iron overload
in the body. Extra iron from chronic transfusions is stored in the liver.
Once the liver stores are full, the iron begins to accumulate in places
like the heart and pituitary, where it can do damage. Iron overload can
also result from increased absorption of iron from the gut, as can be
the case with thalassemia intermedia.
To help keep the iron stores from building up too fast, a medication called
Desferal will be used in conjunction with a low iron diet. Keep the iron
under 10 mg/day for those children under 10 years old, and under 18 mg/day
for those who are 11 years old and older.
Children who have thalassemia and are transfused are still relatively
anemic, so their bodies might still crave iron. As it may be difficult
to watch their diets closely, they should develop good habits early. Remind
children to definitely avoid very high iron foods such as dried beef and
other high iron beef products, even if they are craving it. Remember that
the iron found in meat is much more easliy absorbed than other sources
of iron, such as cereals and breads.
Do not cook with cast iron cookware (e.g. a wok) because iron from the
cookware can transfer onto the food. Some foods, such as orange juice,
can enhance iron absorption, while others, like tea, dairy and coffee,
can decrease absorption. If you are using Desferal, however, it is recommended
that you take 250 mg or less of vitamin C after beginning infusion to
help increase output of iron.
On food labels, the percentage of iron in one serving of that food is
usually listed. This is based on the U.S. Recommended Daily Allowance
of 18 mg/day. If the label says the food contains 8% of the daily recommended
iron, multiply .08 by 18mg to get the mg iron from a serving of that food.
