Malabsorption of iron has been reported in children with symptomatic giardiasis. The aim of this study was to evaluate intestinal absorption of iron in children with asymptomatic giardiasis and iron deficiency anemia. Based upon results of blood hemoglobin and stool examination, two groups were established: asymptomatic giardiasis and anemia, and anemia without intestinal parasitosis (control group). Patients were aged 1-6 years. There was no difference in age, weight, height, or iron nutritional status between the asymptomatic giardiasis and control groups on admission to the study. Intestinal absorption of iron was evaluated using the iron tolerance test and the hemoglobin response to iron therapy. The serum iron tolerance test was based on the increment of iron level 2 hours after administering an iron load of 1 mg/kg of elemental iron in the form of ferrous sulfate, in comparison to the fasting iron level. Hemoglobin response to oral iron therapy was determined by the increment of hemoglobin on day 30 of therapy with ferrous sulfate (5 mg/kg/day of elemental iron). There was no statistical difference between the asymptomatic giardiasis and control groups with reference to the iron tolerance test (159.1 +/- 73.1 micrograms/d...Continue Reading

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
