Insights

This study screened 10,407 individuals for hemoglobinopathies in West Bengal using CE-HPLC. The findings highlight the prevalence of beta-thalassemia trait and HbE carriers, emphasizing the need for population screening.

Area of Science:

  • Medical Genetics
  • Hematology
  • Public Health

Background:

  • Hemoglobinopathies are prevalent genetic blood disorders.
  • Epidemiological identification and population screening are crucial for prevention.
  • Understanding the spectrum of these disorders is vital for public health strategies.

Purpose of the Study:

  • To determine the spectrum of hemoglobinopathies in West Bengal.
  • To evaluate the utility of cation-exchange high-performance liquid chromatography (CE-HPLC) for hemoglobinopathy screening.

Main Methods:

  • A retrospective, single-center, cross-sectional study.
  • Analysis of 10,407 consecutive participants.
  • Screening using cation-exchange high-performance liquid chromatography (CE-HPLC).

Main Results:

  • Out of 10,407 subjects, 85.5% were normal.
  • 5.6% were diagnosed with beta-thalassemia trait (BTT).
  • 5.0% were identified as HbE carriers, with ten additional variants detected.

Conclusions:

  • CE-HPLC is an effective, high-throughput screening tool for hemoglobinopathies.
  • Early detection and management of hemoglobinopathies are feasible.
  • Population screening in West Bengal identified significant prevalence of BTT and HbE carriers.

Electrophoresis: Overview

Electrophoresis is a powerful analytical separation technique that relies on the differential migration of charged species when subjected to an electric field. The core strength of electrophoresis lies in its ability to separate high-molecular-weight species in complex mixtures. It has found widespread use in biochemistry, molecular biology, and analytical chemistry, allowing the separation of compounds like amino acids, nucleotides, carbohydrates, and proteins with excellent resolution.

Capillary Electrophoresis: Instrumentation01:20

Capillary Electrophoresis: Instrumentation

Capillary electrophoresis instrumentation typically consists of several key components. A high-voltage power supply generates the electric field necessary for the separation by connecting to an anode (the positively charged electrode) and a cathode (the negatively charged electrode) located in buffer reservoirs at each end of the capillary tube. The system includes a sample vial, a fused silica capillary tube coated with polyimide for mechanical strength through which the sample components...

Hemoglobin01:24

Hemoglobin

Hemoglobin is a globular protein made up of four subunits. Two of these subunits are alpha chains, and the other two are beta chains. Each subunit contains a molecule of heme, which has an iron atom and can bind to oxygen. When an oxygen molecule binds to one heme group, it changes the shape of hemoglobin, making it easier for the other heme groups to bind oxygen as well.
When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...
