 | | Pathophysiology: Sickle cell anemia is an autosomal recessive genetic disease that results from the substitution of valine for glutamic acid at position 6 of the beta-globin gene, leading to production of a defective form of hemoglobin, hemoglobin S (HbS). |
 | | Sickle pulmonary disease is due to a chronic hypoxic state, recurrent infarctions, and infections. |
 | | Patients who are pregnant and have sickle cell disease are at increased risk for crisis, toxemia, pyelonephritis, thrombophlebitis, and spontaneous abortion compared to the general population. |
