Thalassemia in Asia 2021 Overview of Thalassemia and Hemoglobinopathies in Bangladesh.

Bangladesh is a country with a population of 160 million with a gross national income per capita of US$1580.00. The major health problems in Bangladesh include acute respiratory infection, pneumonia, dengue fever, malaria and water-borne diseases. The health care system in Bangladesh is divided into primary secondary and tertiary levels, with each level having their own breakdown of available hospital beds and other treatment facilities. Thalassemia is a major health problem in Bangladesh. There are two types of thalassemia in Bangladesh: β-thalassemia (β-thal) and Hb E (: c.79G>A)/β-thal, with the prevalence rate of β-thal trait being 4.1% and Hb E trait 6.1%. This study discusses spectrum types of thalassemia and hemoglobinopathies in Bangladesh and the types of carrier detection. The distribution of common mutations of thalassemia are also discussed and the distribution frequencies of genotypes and alleles of β-thal and Hb E patients are also compared. Additionally, we also conducted a study of the spectrum of thalassemia using high performance liquid chromatography (HPLC) of the tribal populations and analyzed the findings in our discussion. The results of these studies show that the phenotypic and genotypic presentation in Bangladesh is highly diverse. To properly understand this, we have to conduct an epidemiological survey of the population. Furthermore, there also has to be improvement on the awareness of thalassemia among the population to properly equip themselves to survive this disease.
