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.
Abstract:
An infant with Hb SE disease is reported. He was clinically well. Review of the literature shows that patients aged 18 and younger are usually well. On the other hand, more than half of those aged 20 and older developed sickling-related complications, including potentially life-threatening acute chest syndrome. These patients have 60-65% Hb S, similar to the percent Hb S in patients with Hb S/beta(+)-thalassemia. Their hematological features and clinical course appear to parallel those of Hb S/beta(+)-thalassemia. Patients have variable levels of anemia, and some develop clinical complications. With population migrations and increasing racial intermarriages, Hb SE disease is expected to be encountered more often around the globe. Patients with Hb SE disease should be followed and managed in a similar fashion as those with Hb S/beta(+)-thalassemia, and treated appropriately when they develop sickling-related symptoms and complications.

Disorders of Erythrocytes
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.
