Clinico-haematological profile of HbE syndrome in adults and children.

Haemoglobin E beta thalassemia (HbE beta thalassemia) has a remarkable variability in clinical expression ranging from a mild form of thalassemia intermedia to a transfusion dependent condition. An overlap between the mild variety of HbE beta thalassemia and homozygous HbE disease is common, however, differentiation is required for early institution of therapy and for predicting the later clinical course. Fifty cases of Hb E syndrome comprising of 43 cases of Hb E beta thalassemia and 7 cases of homozygous HbE disease were studied. Their clinico- haematological features and results of high performance liquid chromatography (HPLC) were analysed.
