Hematological status of beta-thalassemics in Madras.
Although rapid technical advances have taken place in the diagnosis of beta-thalassemia, still the hematological factors were found to be suitable screening test in areas like Indian subcontinent where a high prevalence of beta-thalassemia trait was observed. Among various thalassemias reported in Asian Indians, beta-thalassemia account for about 80% and is responsible for very high infantile mortality. Despite this, little is known about the hematological status of beta-thalassemias among this ethnic group which is associated with more than five different predominant beta-globin mutation with high frequency and variable number of rare ones. The present study is the first report of hematological status of beta-thalassemia among this ethnic group particularly from Tamil Nadu, Southern India, who are still practising high degree of consanguinity. In the present study, a total number of 364 beta-thalassemics were investigated. This includes 84 cases of homozygous beta-thalassemias and the remaining 280 were heterozygotes. The hematological factors such as red cell indices, hemoglobin F and hemoglobin A2 were assessed. The results revealed a wide spectrum of hematological variables ranging from severe form as that of Mediterranean thalassemias to very mild form of anemia as that of African Negro population.
