How does hydroxyurea increase hemoglobin f
WebIn sickle cell anemia, hydroxyurea is thought to increase hemoglobin F cells in red blood cells (RBCs). This decreases the neutrophils and increases the water content of RBCs that alters the formation of sickle-shaped RBCs, so the shape is normal. This reduces the frequency of painful crises and the need for blood transfusions. WebHydroxyurea Since the pediatric hematologist Janet Watson instructed in 1948 that the paucity of sickle cells in the peripheral blood of newborns was due to the presence of increased HbF, there was curiosity in developing therapies to modulate the hemoglobin switch from fetal to new child life and extend HbF manufacturing.
