  1. 1. Sickle Cell Crises Steven Elsbecker DO Peds ICU Presentation November 15th 2013
  2. 2. What We Will Discuss • Prevalence and epidemiology of Sickle Cell Disease • Various Sickle Cell Disease complications • The Sickle Cell Crises • The diagnosis, management and disposition of Sickle Cell Crises
  3. 3. What We Won’t Discuss • Chronic outpatient management • Biochemical and molecular details • Genetic inheritance details
  4. 4. Epidemiology • Hgb SS affects 1:5000 Sub-Saharan African Americans • 1:36000 Hispanic-Americans • 44 States currently perform neonatal screening for sickle cell trait and disease • 1:12 African Americans are carries of the sickle cell trait
  5. 5. Sickle Cell Complications
  6. 6. Skin • Stasis Ulcers
  7. 7. Neuro • CVA 2/2 vaso-occlusion
  8. 8. Eye • Retinopathy 2/2 vaso-occlusion
  9. 9. Pulmonary • Embolism, Infarct, Infection
  10. 10. Vascular • Vaso-occlusion causing downstream ischemia anywhere in the body
  11. 11. Liver • Hepatitis 2/2 blood transfusion cholestasis, hepatic sequestration
  12. 12. Gall Bladder • Cholelithiasis/Cholecystitis
  13. 13. Spleen • Splenic Sequestration
  14. 14. Genitourinary • Hematuria, decreased fertility, impotence, priapism
  15. 15. Bone • Infarct / Aseptic Necrosis osteomyelitis, Aplastic Crisis
  16. 16. Reproductive • Decreased fertility, placental insufficiency
  17. 17. Immunologic • Relative immunodeficiency
  18. 18. Erythrocytes • Hemolysis
  19. 19. The Sickle Cell Crises
  20. 20. The Crises • These 4 general categories cause the most morbidity and mortality • Splenic Sequestration Crisis • Hemolytic Crisis • Aplastic Crisis • Vaso-occlusive Crisis
  21. 21. Splenic Sequestration Crisis • Splenic engorgement • Rapid drop in Hgb • Circulatory collapse • 3-24 hours • Transfusion/Exchange
  22. 22. Hemolytic Crisis • Acute, accelerated breakdown • Oxidative stress • Infection • Hypoxia… • More common with concomitant G6PD deficiency
  23. 23. Aplastic Crisis • Supply:Demand mismatch • Most commonly follows Parvo B19 • Reticulocyte count • Critical drops in Hgb
  24. 24. Vaso-Occlusive Crisis • The cause of nearly all SCD complications • Abnormal cells stack in small vessels • Shunt = Ischemia = Pain • Can cause any symptom 2/2 end organ ischemia
  25. 25. Acute Chest Syndrome • Concomitant infarction and infection • High morbidity and mortality • Treat pain, hypoxia and infection • Macrolides or Quinilones
