Abstract:
Objective: To compare the effects of different hemolytic diseases on the level of glycosylated hemoglobin (HbA(1c)) to further explore the relationship between HbA(1c) and laboratory indexes to disclose implications of HbA(1c) in hemolytic diseases. Methods: The distribution of 192 decreased HbA(1c) cases in 4 categories of hemolytic diseases was analyzed. Laboratory indexes related to hemolysis were tested and analyzed in each kind of disease, and relationship between laboratory indexes and HbA(1)c was statistically explored. Results: Diagnoses of decreased HbA(1c) cases mainly included erythrocyte membranopathies (88 cases), immunohemolytic anemia (72 cases), hemoglobinopathy (4 cases) and erythrocyte enzymopathy (5 cases). The distribution of HbA(2) and normal HbF subjects in immunohemolytic anemia and hemoglobinopathy was significantly different from those of HbA(2) and / or abnormal HbF subjects (41.7% vs 22.0%, χ(2)=5.574, P=0.018; 0.7% vs 7.3%, P=0.031). Compared with non-hemolytic disease patients, those who suffered from 4 categories of hemolytic diseases showed lower HbA(1c) level and higher reticulocyte percentage (Ret), indirect bilirubin (IBIL) and free hemoglobin (F-Hb). Different levels of Ret, reticulocyte hemoglobin content (Ret-He), mean corpuscular volume (MCV), IBIL and F-Hb among the 4 kinds of diseases were observed, but the causes of the differences were not the same. HbA(1c) was negatively correlated with other laboratory indexes in erythrocyte membranopathies and immunohemolytic anemia. Conclusions: Hemolytic disease resulted in false lower HbA(1c), but impact of difference on HbA1c between different diseases was not significant. HbA(1c) was closely connected to laboratory indexes related to hemolysis, which might have potential implications for hemolytic diseases such as erythrocyte membranopathies and immunohemolytic anemia.
