Abstract
Aim of investigation. To estimate hematological disorders in patients with high titer of anti-parietal cell antibodies (APCA). Material and methods. Overall 71 patient with high serum APCA titer were included in original study. At all patients scores of clinical and biochemical blood tests were investigated. The special attention was given to RBC color index (CI), mean corpuscular volume (MCV), mean hemoglobin content per cell and serum iron and vitamin В12 concentration. Results. The mean indices of clinical and biochemical blood tests in APCA-positive patients were within normal range. Hematological changes were revealed in 25,4% of patients. In 11,3% of the cases either macrocytic or microcytic anemia was diagnosed. Increase in mean corpuscular volume and serum cobalamin level were found out in 16,9% of the cases, while low hemoglobin level - only at 25% of them. No Helicobacter pylori infection has been revealed in the patients with macrocytic anemia, however no significant difference on its prevalence in patients with different serum cobalamin level was found out. Conclusion. The majority of cases with high APCA titer has no hematological signs of autoimmune gastritis. In 25,4% of patients with APCA changes in common blood count were revealed, most often - of MCV and the CI. Anemia was diagnosed in 11,3% of patients. In investigated group cobalamin deficiency was found in 16,9% of patients, iron deficiency - in 9,9% of the cases. In 75% of patients increase in MCV was the only sign of cobalamin deficiency. Iron deficiency was more common in women.
