Summary
This study analyzed hemoglobin types in 74 sickle cell disease patients experiencing bone pain. Findings suggest elevated Hemoglobin A2 levels may indicate sickle cell beta-thalassemia in some patients.
Area of Science:
- Hematology
- Medical Biochemistry
Background:
- Sickle cell disease (SCD) is a group of inherited red blood cell disorders.
- Accurate hemoglobin typing is crucial for diagnosing SCD subtypes and guiding treatment.
- Bone pain is a common and debilitating symptom in SCD patients.
Purpose of the Study:
- To quantitatively reassess hemoglobin types in sickle cell patients with bone pain.
- To investigate the significance of elevated Hemoglobin A2 levels in SCD.
- To explore the potential presence of sickle cell beta-thalassemia.
Main Methods:
- Biochemical analysis of hemoglobins was performed on blood samples from 74 patients.
- Cellulose acetate electrophoresis was used for quantitative hemoglobin reassessment.
- Hemoglobin A2 and alkali-resistant hemoglobin levels were determined.
Main Results:
- Sixty-five patients had Hb S/S disease, five had Hb A/S, and four had Hb A, S, and C.
- Elevated Hemoglobin A2 levels were observed in a subset of patients.
- Alkali-resistant hemoglobin was measured in 29 cases.
Conclusions:
- The presence of elevated Hemoglobin A2 warrants further investigation for sickle cell beta-thalassemia.
- Accurate hemoglobin analysis is vital for understanding SCD pathophysiology.
- This study contributes to the diagnostic understanding of SCD variants.

Overview
01:27Glucose Transporters
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

01:27Disorders 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.

01:20Inborn Errors of Metabolism
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
