ABSTRACT
OBJECTIVE@#To analyze the hematological characteristics of HbE homozygotes.@*METHODS@#Complete blood cells count and hemoglobin electrophoresis were used for phenotypic analysis of 78 cases with HbE homozygotes from Yunnan province, China. The PCR-fluorescence hybridization was used to detect the common gene mutation of thalassemia. The hematological indexes, including MCV, MCH, Hb, HbA2, HbF and HbE were statistically analyzed between groups with different sex, ages and compound α thalassemia status.@*RESULTS@#In HbE homozygotes (HbEE), 89.5% (17/19) children presented mild to moderate microcytic hypochromic anemia, and 10.5% of them presented moderate anemia. 39.6% (19/48) of women with HbEE developed mild anemia ,while 11 cases of male with HbE homozygotes were asymptomatic. The levels of MCV and MCH in HbE homozygotes increased by co-inheritance of α thalassemia mutation.@*CONCLUSION@#The clinical phenotype of HbE homozygote shows highly heterogeneous, which is relates with age, sex and co-inheriting α-globin genotypes. In Hb EE women and children are more likely to develop mild to moderate anemia. The microcytic hypochromic anemia degree is relieved when HbEE combined with α- thalassemia.
