Q

Abnormal Hgb gene = Hgb Sickle gene. Sickle shaped RBC’s that clump together. 60-65%; most severe. 1 of every 400-600 African American births. Autosomal recessive (gene from each parent). Fetal Hgb protects from sickling for 1st 4-6 months.

Q

Physiologic Stress causes: dehydration, fever, hypoxia, hypothermia, acidosis leading to sickling. Sickled RBC’s adhere, clump, clog causing vasoocclusion and thickening of circulating blood. Blood flow blocked, O2 and nutrient delivery blocked leading to pain and tissue damage. Sickled cells die more quickly than normal RBC’s, so low RBC count leads to hemolytic anemia. Free iron from lysed RBCs deposits in organs/tissues causing more damage. TISSUE INJURY/DEATH BY OCCLUSION AND HEMOLYSIS

Q

Can affect entire body. Decreased O2 in tissues causes infarcts at the site of occlusion equalling cellular death and pain. Under 5 years the bones and hands and feet can lead to dactylitis, edematous, erythemous leading to ulcers. Can lead to stroke/neuro injury so CLOSE NEURO MONITORING. Acute chest (pulm vessels)- EMERGENCY. Mimics pneumonia - cough, fever, chest pain, tachypnea, dyspnea, resp distress. Coronary vessels/cardiac muscle. Spleen becomes fibrotic and stops working leading to increased risk of infection. Gallstones and hepatomegaly, sometimes liver failure. Infects kidney filtration and ability to concentrate urine (hematuria). Infarcts affect penile circulation; poor circulation to testes and ovaries causing infertility. Retinal ischemia, detachment

Q
