Insights

Hemoglobin SE (Hb SE) disease is often mild in children but can cause serious complications in adults. Management should mirror that of Hb S/beta(+)-thalassemia.

Area of Science:

  • Hematology
  • Genetics
  • Pediatrics

Background:

  • Hemoglobin SE (Hb SE) disease is a hemoglobinopathy.
  • It arises from compound heterozygosity for Hb S and Hb E.
  • This condition is increasingly recognized globally due to population migration.

Observation:

  • A case of an infant with Hb SE disease who was clinically well is presented.
  • Literature review indicates that individuals under 18 with Hb SE disease are typically asymptomatic.
  • Conversely, over 50% of patients aged 20 and older experience sickling-related complications.

Findings:

  • Hb SE disease patients exhibit 60-65% Hb S, comparable to Hb S/beta(+)-thalassemia.
  • Hematological parameters and clinical progression in Hb SE disease resemble those in Hb S/beta(+)-thalassemia.
  • Variable anemia and the potential for clinical complications are noted in Hb SE disease.

Implications:

  • Hb SE disease is expected to be diagnosed more frequently worldwide.
  • Management strategies for Hb SE disease should align with those for Hb S/beta(+)-thalassemia.
  • Prompt treatment of sickling-related symptoms and complications is crucial for patients with Hb SE disease.

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...

Disorders of Erythrocytes

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...
Oxygen Transport in the Blood01:27

Oxygen Transport in the Blood

Hemoglobin (Hb) is a crucial molecule in the human body, consisting of four polypeptide chains, each bound to an iron-containing heme group. This unique structure enables hemoglobin to bind to oxygen, with each molecule capable of combining with four molecules of oxygen, leading to rapid and reversible oxygen loading. When fully loaded with oxygen, it is called oxyhemoglobin, while hemoglobin that has released oxygen is called reduced hemoglobin or deoxyhemoglobin. As hemoglobin binds oxygen,...
Gene Families01:57

Gene Families

Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...
