Aims of the Study : Hereditary spherocytosis (HS) is a familial hemolytic disorder manifesting as anaemia, recurrent jaundice, splenomegaly with marked heterogeneity in clinical presentation. The objective was to study the clinical spectrum of the disorder in India. Methodology : We studied 50 HS patients and followed them for upto six years (Age range 2-47 years). Results : The presenting features were jaundice 35 out of 50, anaemia 30 out of 50 (requiring blood transfusion in 25). Splenomegaly was found in all patients. Increased osmotic fragility was found in all patients whereas spherocytes were found in only 19 out of 42 patients. Reduced red cell survival was noted in 9/12 patients studied with 51Cr labeled RBCs. There was a definite improvement in the hemoglobin values in those who underwent splenectomy. Thirteen cases had similarly affected family member/s. Fifteen of the cases had family history consistent with autosomal dominant (AD) inheritance (eight families) while in six cases (5 families), inheritance was likely to be autosomal recessive (AR). There was intrafamilial variability in the age of presentation in the AD families.Conclusions : Our results suggest that both autosomal dominant and recessive patterns of HS are seen in India and the clinical profile of the Indian HS patients is similar to that described in other populations. HS presenting in childhood is also not uncommon. However, the predominant underlying protein defect in Indian patients needs to be characterized.
