Background: Anagrelide is a drug used for treatment of essential thrombocytosis especially when conventional therapy is insufficient. Adverse effects associated with anagrelide are palpitation, liver toxicity, renal failure and in few cases pericardial effusion. We here report a rare case of anagrelide induced pericardial effusion. Case Presentation: A 76-year-old male with past medical history of hypertension, hyperlipidemia, chronic obstructive pulmonary disease, and myeloproliferative disorder presented to the emergency department with dyspnea on rest and exertion. He was initially treated with hydroxyurea for thrombocytosis but was later switched to anagrelide. On examination patient had muffled heart sounds. Lab investigations identified hyperkalemia and transaminitis. Transthoracic echocardiogram identified a moderate sized pericardial effusion. The pericardial effusion and transaminitis were attributed to anagrelide toxicity as other causes were ruled out. Pericardiocentesis was performed and anagrelide was discontinued. Patient was discharged in a well-compensated state with outpatient follow-up in two to three weeks. Conclusion: Anagrelide is considered to be very effective treatment for essential thrombocytosis. It is, however, associated with serious adverse effects such as pericardial effusion, liver toxicity and palpitations. The mechanisms of these adverse drug reactions are still not completely understood. We suggest that patient taking anagrelide presenting with shortness of breath should have a transthoracic echocardiogram performed to rule out pericardial effusion. Liver enzymes should also be monitored closely and anagrelide discontinued immediately if the above-mentioned adverse events are noted. [ABSTRACT FROM AUTHOR] |
