Thalassemia in India

Hemoglobin. 2022 Jan;46(1):20-26. doi: 10.1080/03630269.2021.2008958.

Abstract

Management and control of hemoglobinopathies are a challenge in India where 67.0% of people reside in rural regions. The GDP spent on health is one of the lowest (1.3%) resulting in high out-of-pocket expenses. The β-thalassemias are prevalent with an estimated 7500-12000 new births each year. Hb S (HBB: c.20A>T) and Hb E (HBB: c.79G>A) are also common regionally. Over 80 β-thalassemia (β-thal) mutations have been characterized in Indians. The δ gene mutations are increasingly being described and their coinheritance in β-thal carriers leads to a reduction in Hb A2 levels and a misdiagnosis of carriers. Around 15-20 centers offer prenatal diagnosis (PND) mainly in urban regions. The projected annual cost of care of β-thal patients over a decade (2016-2026) will increase from INR30,000 (US$448) million to INR55,000 (US$820) million if all patients are adequately treated. Cost comparisons are difficult to make with other international studies as the standard of care, cost of medicines and other services vary in different countries. Several centers provide hematopoietic stem cell transplants (HSCTs) for thalassemias, however, only around 250 HSCTs are done annually. Although the cost is high, financial assistance is available for a few patients. There are disparities in the quality of care and to address this a National Policy has been proposed for the management and prevention of hemoglobinopathies that will embark on a comprehensive program, providing adequate care and augmenting the existing public health care services. It will also include training, genetic counseling and easier access to preventive options and a National Registry.
