BACKGROUND: Co-inheritance of structural hemoglobin variants like HbS, HbD(Punjab) and HbE can lead to a variable clinical presentation and only few cases have been described so far in the Indian population. METHODS: We present the varied clinical and hematological presentation of 22 cases (HbSD(Punjab) disease-15, HbSE disease-4, HbD(Punjab)E disease-3) referred to us for diagnosis. RESULTS: Two of the 15 HbSD(Punjab) disease patients had moderate crisis, one presented with mild hemolytic anemia; however, the other 12 patients had a severe clinical presentation with frequent blood transfusion requirements, vaso occlusive crisis, avascular necrosis of the femur and febrile illness. The 4 HbSE disease patients had a mild to moderate presentation. Two of the 3 HbD(Punjab)E patients were asymptomatic with one patient's sibling having a mild presentation. The hemoglobin levels of the HbSD(Punjab) disease patients ranged from 2.3 to 8.5 g/dl and MCV from 76.3 to 111.6 fl. The hemoglobin levels of the HbD(Punjab)E and HbSE patients ranged from 10.8 to 11.9 and 9.8 to 10.0 g/dl whereas MCV ranged from 67.1 to 78.2 and 74.5 to 76.0 fl respectively. CONCLUSIONS: HbSD(Punjab) disease patients should be identified during newborn screening programmes and managed in a way similar to sickle cell disease. Couple at risk of having HbSD(Punjab) disease children may be given the option of prenatal diagnosis in subsequent pregnancies.
