Side Effects by Body System - for Healthcare Professionals

Applies to: compounding powder; intravenous solution

Cardiovascular

Cardiovascular side effects can include QT interval prolongation and complete atrioventricular block. QT prolongation can lead to a torsade de pointes-type ventricular arrhythmia, which can be fatal. Tachycardia (up to 55%), ECG QT corrected interval prolonged > 500 msec (up to 38%), palpitations (up to 10%), and ECG abnormalities other than QT interval prolongation (up to 7%) have been reported. One patient (also receiving amphotericin B) had torsade de pointes during induction therapy for relapsed APL with arsenic trioxide.

The risk of torsade de pointes is related to the extent of QT prolongation, concomitant administration of QT prolonging drugs, a history of torsade de pointes, preexisting QT interval prolongation, congestive heart failure, administration of potassium-wasting diuretics, or other conditions that result in hypokalemia or hypomagnesemia

Other

The management of the syndrome has not been fully studied, but high-dose steroids have been used at the first suspicion of the APL differentiation syndrome and appear to mitigate signs and symptoms. At the first signs that could suggest the syndrome (unexplained fever, dyspnea and/or weight gain, abnormal chest auscultatory findings or radiographic abnormalities), high-dose steroids (dexamethasone 10 mg intravenously BID) should be immediately initiated, irrespective of the leukocyte count, and continued for at least 3 days or longer until signs and symptoms have abated. The majority of patients do not require termination of arsenic trioxide therapy during treatment of the APL differentiation syndrome.

Other side effects similar to a syndrome called the retinoic-acid-Acute Promyelocytic Leukemia (RA-APL) or APL differentiation syndrome have been reported. This syndrome is characterized by fever, dyspnea, weight gain, pulmonary infiltrates, and pleural or pericardial effusions (with or without leukocytosis). The syndrome can be fatal.
