Blue baby syndrome can refer to conditions that cause cyanosis, or blueness of the skin, in babies as a result of low oxygen levels in the blood. This term has traditionally been applied to cyanosis as a result of:. [1] Cyanotic heart disease, which is a category of congenital heart defect that results in low levels of oxygen in the blood. [2]
At birth, hemoglobin F accounts for 50-95% of the infant's hemoglobin and at around 6 months after birth, hemoglobin A becomes the predominant type. By the time the baby is one year old, the proportions of different types of hemoglobin are expected to approximate the adult levels, with hemoglobin F reduced to very low levels. [4]
Cyanosis is the change of body tissue color to a bluish-purple hue, as a result of decrease in the amount of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. [1] Cyanosis is apparent usually in the body tissues covered with thin skin, including the mucous membranes, lips, nail beds, and ear lobes. [1]
A savior sibling may be the solution for any disease treated by hematopoietic stem cell transplantation.It is effective against genetically detectable (mostly monogenic) diseases, e.g. Fanconi anemia, [4] Diamond–Blackfan anemia [5] and β-thalassemia, in the ailing sibling, since the savior sibling can be selected to not have inherited the disease.
A diagnosis of DBA is made on the basis of anemia, low reticulocyte (immature red blood cells) counts, and diminished erythroid precursors in bone marrow. Features that support a diagnosis of DBA include the presence of congenital abnormalities, macrocytosis, elevated fetal hemoglobin, and elevated adenosine deaminase levels in red blood cells ...
The use of r-EPO did not decrease the average number of transfusions in the infants born at less than 1000 g, or the percentage of infants in the 1000 to 1250 group. A multi-center European trial studied early versus late r-EPO in 219 infants with birth weights between 500 and 999 g.

Hgb - the infant's hemoglobin should be tested from cord blood. [5] Reticulocyte count - Reticulocytes are elevated when the infant is producing more blood to combat anemia. [5] A rise in the reticulocyte count can mean that an infant may not need additional transfusions. [18]
