Background
- Differentiation syndrome (DS) is most current term
- APML pts undergoing ATRA treatment (Tretinoin, Vesanoid)
- And/or with arsenic trioxide therapy (Trisenox, ATO)
- ATRA differentiates APML blasts into mature granulocytes
- Differentiation of blasts may cause "cytokine storm" and lead to tissue damage
- Incidence of DS[1]
- Up to 25% of pts undergoing ATRA Tx
- Up to 31% of pts undergoing ATO Tx
- Up to 40% mortality in patients requiring mechanical ventilation
- Diagnosis made clinically with symptomology and includes immediate treatment with steroids
- Steroid treatment highly recommended even if other ddx possible
Differential
- Sepsis
- Fungal infection
- Pulmonary hemorrhage
- Pneumonia
- Renal failure
- CHF
- Pulmonary embolism
- DIC
Clinical Features
- Unexplained fever
- Unexplained hypotension
- Weight gain > 5 kg
- Dyspnea with pulmonary infiltrates
- Pericardial effusion
- Pleural effusion
- Renal failure
- Vascular capillary leak syndrome
- DIC
- Never observed beyond induction therapy, when pt has achieved complete response
Diagnostics
- Troponins for pericarditis
- Severe leukocytosis on CBC
- Sepsis workup
- CHF workup, echo
- Pulmonary embolism workup
- DIC workup
- Diagnostic bronchoscopy, BAL, bx usually not required
- Imaging
- CXR - pleural effusions, ground-glass opacities, increased cardiac silhouette
- CT chest - pleural effusions, peripheral nodules
Management[2]
- Dexamethasone 10 mg IV q12hrs
- Continue treatment until complete disappearance of signs and symptoms
- Temporary d/c ATRA or ATO only in severe cases of DS (renal failure or ICU admit)
- Furosemide for fluid overload
- CRRT for refractory renal failure
- Supportive
- Mechanical ventilation for respiratory failure
- Careful IVF admin, prioritizing blood products for coagulopathies (DIC)
- Vasopressors
- Empiric antibiotics
- Avoid invasive pleural/pericardial effusion diagnostics
