Hb H disease: clinical course and disease modifiers
2009年1月1日 · In this chapter we will review the molecular defects leading to Hb H disease, and its clinical manifestations, diagnosis, and management. We will also discuss possible modifiers at both the genetic and environmental levels that may modify its clinical severity.

2023年9月4日 · Hemoglobin H disease (alpha-thalassemia) can be found in patients that live in areas with a high incidence of malaria. Symptoms at presentation, such as episodic anemia, and appropriate diagnostic testing, such as hematology studies and electrophoresis, are essential to timely and proper treatment.
The Diagnosis of α-Thalassaemia: A Case of Hemoglobin H −α
Electropherogram of the alkaline hemoglobin electrophoresis (pH 8.6) conducted on the HELENA SASII system for the patient sample. Lane 1: AFSA2 pack Control, Identities of the migrating bands are indicated on the figure. Lane 2: Patient sample shows the presence of a putative HbH band migrating ahead of HbA

2024年2月9日 · Hemoglobin analysis: HPLC or electrophoresis can quantify the different hemoglobin types in the patient’s blood (see Image. α-Thalassemia Major on Hemoglobin Electrophoresis). These techniques can also help differentiate different thalassemia types with good precision and reproducibility.
• Principle: proteins when applied to a membrane and exposed to a charge gradient, separate and can be visualized by protein or haem stain. Sample: Packed red cells; if whole blood used paraprotein or high concentration of polyclonal Ig may produce a band.

Hemoglobin H and hemoglobin Barts are fast-moving hemoglobins that may appear on electrophoresis. However, they are unstable and often go undetected. Patients with hemoglobin H disease have greater than 20 percent hemoglobin Barts at birth.
Hemoglobin Electrophoresis: Test, Procedure & Results - Cleveland Clinic
2022年2月11日 · Hemoglobin electrophoresis is the process healthcare providers use to analyze hemoglobin in your red blood cells. Hemoglobin electrophoresis helps diagnose serious conditions like sickle cell anemia. It’s also one of several tests that screen newborn babies for sickle cell anemia and other rare but serious illnesses.
Alpha- and Beta-thalassemia: Rapid Evidence Review - AAFP
Hemoglobin electrophoresis may reveal common characteristics of different thalassemia subtypes, but genetic testing is required to confirm the diagnosis. Thalassemia is generally asymptomatic...

2005年11月1日 · Alpha-thalassemia (α-thalassemia) has two clinically significant forms: hemoglobin Bart hydrops fetalis (Hb bart) syndrome (deletion/inactivation of all four alpha globin [α-globin] genes; --/--), and hemoglobin H (HbH) disease (most frequently caused by deletion/inactivation of three α-globin genes; --/-α) (see Figure 1). Figure 1.
Hemoglobin electrophoresis - Wikipedia
Hemoglobin electrophoresis is a blood test that can detect different types of hemoglobin. The test can detect hemoglobin S, the form associated with sickle cell disease, as well as other abnormal types of hemoglobin, such as hemoglobin C. It can also be used to investigate thalassemias, which are disorders caused by defective hemoglobin production.
