The purpose was to identify the frequency of occurrence of various morphological types and different degrees of severity of anemia in patients with autoimmune thyroiditis (AIT).

Material and methods: Were analyzed 97 case histories of patients operated for AIT in 2012. When assessing hematological parameters, two groups were identified: group 1 – patients with AIT with mild anemia (n= 72), age 45.7 ± 1.6, men - 5 (6.9%), women - 67 (93, 1%); group 2 - patients with AIT with moderate anemia (n= 25), age 40.0 ± 2.3, men - 1 (4%), women - 24 (96%). In the clinical analysis of blood, hemoglobin, hematocrit, the number of erythrocytes and erythrocyte indexes of MCV, MCH, MCHC were determined.

Results: In patients with AIT with a mild degree of anemia, microcytic anemia was determined in 55 (76.4%), normocytic - in 17 (23.6%) patients. In moderate anemia, microcytic anemia was detected in 21 (84%) patients, normocytic anemia - in 4 (16%) patients. hypochromic type of anemia in the group ‘all patients‘ was noted in 79 (81.4%), normochromic type in 17 (17.5%) and hyperchromic in 1 (1%) patient. By morphological type in patients with AIT with mild anemia, the hypochromic type was observed in 56 (77.8%) patients, normochromic - in 16 (22.2%) patients. In moderate anemia, this tendency was more pronouned: hypochromic type of anemia was detected in 23 (92%) patients, normochromic type - in 1 (4%) and hyperchromic in 1 (4%). Thus, in patients with AIT, mild anemia was more often determined (in 72.4%), then moderate anemia (in 25.7%). With moderate severity of anemia, microcytic (84%) and hypochromic (92%) types of anemia were more often observed. With mild anemia, the same types of anemias were observed, but with a lower frequency (76.4% and 77.8%, respectively).

Conclusion: The hemogram in patients with AIT was characterized by a more frequent development of mild anemia (72.4%). With mild anemia, hematological disorders were characterized by microcytic (76.4%) and hypochromic (77.8%) types of anemia. Similar, but more pronounced disorders were observed in moderate anemia: microcytic 84% and hypochromic 92%, which is characteristic for iron deficiency anemia.
