HbA1cMonitoring in Patients With Type 2 Diabetes Mellitus Treated with Iron Deficiency Anemia

Özet

Objective: The global prevalence of iron deficiency anemia (IDA), one of the commondiseases, is 24.8%, while prevalence of diabetes mellitus is 8.8%. HbA1c used in the diagnosis and follow-up of diabetes mellitus (DM) may not correlate with fasting blood sugar in iron deficiency anemia. The aim of the study was to evaluate the effect ofiron deficiency anemia treatment on HbA1c in patients with type 2 DM. Methods: Patients included in the study were the individuals who have been diagnosed with DM for at least one year and are taking regular medication. Sixty one individuals with DM without iron deficiency anemia constitute the control group; DM and iron deficiency anemia together 33 individuals constitute the patient group. Hemoglobin, iron, ferritin, fasting blood sugar and HbA1c levels were recorded in the first encounter of all patients. The group with iron deficiency anemia continued with existing DM treatments and iron treatment was measured and after three months, all patients were called for control and theirlaboratory values were measured again. Results: Sixty three of the participants were female and 31 were male; the average age was 59.93. Before the treatment of iron deficiency anemia among the participants, the mean HbA1c was 6.68±1.11, and after three months of iron deficiency treatment, the mean HbA1c decreased to 6.58±0.93. While the average of the first HbA1c of the individuals in the control group was 6.38 ± 0.78, it was found as 6.37 ± 0.78 in the measurements after three months. Conclusion: HbA1c, used in the diagnosis and follow-up of diabetes, can be affected by many metabolic conditions, especially iron deficiency. These conditions should be considered in the presence of HbA1c incompatible with fasting blood sugar. However, further research is needed on the subject.
