Abstract
Background: Pericarditis is a rare side-effect of chemotherapy and has been reported following administration of cyclophosphamide, doxorubicin and other drugs but not treosulfan. Case Reports: We report on 2 patients with retrosternal chest pain and typical widespread upward concave ST-segment elevation in the 12-lead electrocardiogram prompting the diagnosis of acute pericarditis. The patients had received treatment for multiple myeloma or relapsed mantle cell lymphoma with high-dose treosulfan alone or in combination with etoposide and carboplatin followed by autologous stem cell transplantation 5 days before onset of the symptoms. In both patients, no serological evidence of viral infection was found. Serum creatine kinase and serum cardiac troponin I remained unchanged. Within 24 h of onset of the symptoms, C-reactive protein increased from normal values (< 5 mg/l) to 95 mg/l and 115 mg/l, respectively. In one of the patients, a paroxysmal supraventricular arrhythmia occurred that persisted for 2 days. After treatment with diclofenac, both patients recovered completely within 1 week. Conclusion: The differential diagnosis of chest pain in the setting of high-dose chemotherapy with e.g. treosulfan should include pericarditis. The pathogenesis remains unclear. Alongside infections, direct toxic or immunological drug-related mechanisms are suggested.
