Özet

Objective: Iron deficiency anemia (IDA) has been demonstrated to be a risk factor for thromboembolic events, although the pathogenesis of the development of thromboembolism in IDA is as yet unclear. The likelihood of children with IDA contracting hypercoagulability was evaluated in this cross-sectional study using rotational thromboelastometry (ROTEM). Material and Method: A total of 57 children with IDA (median age 11 years; 37 female, 20 male) and 48 healthy children (median age 9.9 years; 23 female, 25 male) were enrolled in the study. Whole blood count, serum iron, transferrin saturation, ferritin level, prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen levels were ascertained, while ROTEM assays [intrinsic TEM (INTEM) and extrinsic TEM (EXTEM)] were used to measure and analyze coagulation time (CT), clot formation time (CFT), maximum clot firmness (MCF) and rate of maximum lysis (ML60%). This study conforms to ethical standards, has been approved by the appropriate Institutional Review Board. Results: Hemoglobin, serum iron, transferrin saturation and ferritin levels were lower in the IDA group than in the control group (p < 0.001, for all), while the EXTEM and INTEM CT in the two groups were similar (p > 0.05). The EXTEM and INTEM MCF in the IDA group was higher than in the control group, while the INTEM CFT and rate of ML60% were lower than in the control group (p < 0.001, p < 0.001, p < 0.05, p < 0.001, respectively). Conclusion: The ROTEM results suggest that although the platelet count and coagulation tests were within normal ranges in IDA, the tendency to coagulate may have been increased.
