Özet

Objectives: Iron deficiency anemia (IDA) is the most common type of anemia in childhood and it leads to a hypercoagulable state. We investigated endogenous thrombin production in platelet-poor plasma before and after oral iron replacement in children with IDA using the thrombin generation assay (TGA). Methods: A total of 72 children diagnosed with IDA (IDA group) and 60 healthy children (control group) were included in the study. Blood samples were collected from the patients before and 1 month after oral iron replacement. TGA parameters [lag time, time to peak, peak height, endogenous thrombin potential (ETP)] were studied. Results: In the IDA group, the lag time and time to peak decreased by 8.3% and 10.6%, respectively, and the endogenous thrombin potential (ETP) and peak height both increased by 30% compared to those of the control group. Compared to the values before iron replacement, 1 month after iron replacement, the lag time and time to peak increased by 8.7% and 5%, respectively, and the ETP and peak height decreased by 31% and 31.3%, respectively, and became similar to those of the control group. Conclusion: Children with IDA have increased endogenous thrombin production in platelet-poor plasma and a tendency for hypercoagulability. These changes are reversible, and the ETP values become similar to those of healthy children 1 month after iron replacement.
