The prevalence and characterization of β-thalassemia trait by using high-performance liquid chromatography among the rural population in West Bengal, India
Hemoglobinopathies, common genetic disorders of hemoglobin, can be prevented by population screening and genetic counseling. Identification of these disorders is immensely important epidemiologically and aid in prevention of more serious hemoglobin disorders. Thalassemia is the commonest monogenic disorder in India, which belongs to the thalassemia belt of the world. The present study was undertaken to find out the characteristics of β-thalassemia trait and spectrum of this disorder among the rural population, screened under the hospital-based screening program in West Bengal, a state in eastern part of India. This study was carried out in school and college students, newly married couples and pregnant women after proper counseling in the rural areas of five southern districts of this state. Blood samples were tested by high-performance liquid chromatography. Total 1429 β-thalassemia traits were detected by random screening from this population. The mean value of HbA2 of the study population, having β-thalassemia trait is 4.9%. The prevalence (10.5%) of β-thalassemia trait in West Bengal is higher than other parts of the country. These data are likely to help us in future planning for screening programmes in rural areas of West Bengal, India.
