Abstract:
Globally, hemoglobin (Hb) E beta thalassemia accounts for approximately half the severe forms of beta thalassemia. Because of its wide clinical diversity and the ability of patients with this condition to adapt unusually well to low hemoglobin levels, the management of Hb E beta thalassemia, particularly the decision to instigate regular blood transfusion, is particularly difficult. Here, we present a summary of our work in patients with this condition, which attempts to define clinical, adaptive, and genetic factors of possible value in determining the early management of this condition.

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.
On the other...
Erythropoiesis
Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
