Background
- Sickle cell disease is the most common monogenetic disorder worldwisde affecting 30 million people
- Disease can manifest with vaso-occlusion(pain), acute chest syndrome, stroke, aplastic anemia, priapism
Precipitating Factors
- For vaso-occlusion:
- cold weather
- hypoxia
- infection
- dehydration
- acidosis
- alcohol intoxication
- emotional stress
- pregnancy
- exertional stress
- For aplastic crisis:
- parvovirus B19 infection
- folic acid deficiency
- For acute chest syndrome:
- fat embolus
- infection
- pain crisis
- asthma
Diagnosis
Insert
Work-Up
- CBC / stat hemaglobin
- Assess change in anemia
- Chemistry / LFT / lipase
- If abd pain, may develop cholecystitis, mesenteric ischemia, or perforation
- Reticulocyte count (if aplastic crisis considered) -rare in adults
- CXR
- If cough, sob, or febrile
- O2
- If pain crisis or hypoxic; otherwise may inhibit erythopoesis
- ECG
- T&S/T&C
- BCx2
- VBG
- UA
- Urine pregnancy
- Head CT/MRI if symptoms of stroke
DDx
- ACS
- anemia (acute, chronic)
- appendicitis
- cholecystitis
- gout
- hepatitis
- meningitis
- osteomyelitis
- pancreatitis
- PID
- pneumonia
- priapism
- pulmonary embolism/infarction
- rheumatic fever
- sepsis
- stroke (ischemic or hemorrhagic)
- UTI
- URI
Treatment
- Abd Pain
- Surgery if abdominal injury
- Aplastic Anemia
- Exculde reverible causes and tranfuse for severe anemia (Hb <6-7)
- Pain crisis
- IVF, pain meds, O2 if hypoxic
- Priapism
- Pain meds, exchange tranfusion before surgery, urology consult
- Acute chest syndrome
- Admit if infiltrate, treat pain, give IV Abx
- Stroke
- Head CT +/- LP, IVF, keep HbS <30% total blood vol
Disposition
- Admission if:
- Acute Chest Syndrome - pain/pulmonary infiltrates from infection or pulm infarct
- Stroke, priapism, serious bacterial infection, aplastic crisis, hypoxia, acidosis
- Unable to tolerate PO or inadequate pain control, abnormal vital signs
- Consider if pregnant (in crisis), or uncertain dx of SCD
