We present an unusual manifestation of tuberculosis in a patient on hemodialysis. A 73-year-old woman was admitted to our hospital with a picture of fever, dyspnea and weight loss. She had chronic renal failure and had started periodic hemodialysis 5 years before. Fifteen days after admission, she began with pancytopenia, abnormal liver function and coagulopathy. A bone marrow aspiration was made 1 week later showing macrophage elements with phagocytic activity. Eight weeks later, bone marrow culture in Lowenstein media confirmed the presence of tuberculosis. After the beginning of antituberculosis therapy, the laboratory disturbances disappeared and the clinical situation improved. We think that fever of unknown origin and pancytopenia in patients on maintenance hemodialysis must lead to an early bone marrow biopsy or aspiration since after the diagnosis a specific therapy can cure the disease.

Anthracyclines are very potent drugs in the therapy of malignancies in childhood. The major dose limiting adverse effect of these drugs is the risk of dilated cardiomyopathy. We performed a retrospective study on 168 patients who were treated with anthracyclines for a malignant disease with or without chest radiation at the department of Pediatric Hematology and Oncology at the University of Duesseldorf between 2000 and 2004. During and after chemotherapy the patients were screened by echocardiography and ECG examinations prior to each administration of anthracyclines. Only four patients presented with adverse cardiac events, one of whom developed acute cardiac failure. This patient was additionally treated with chest radiation. Three of the four patients showed intermittent arrhythmias, mainly supraventricular tachycardia. One of them presented with atrial ectopic tachycardia and left ventricular dysfunction. We conclude that the frequency of cardiac sequelae after chemotherapy with anthracyclines is low under present guidelines. Detection of early cardiac sequelae may be more difficult than in the past. Only one patient with cardiac sequelae in our study group was diagnosed by regular performed examinations for cardiac sequelae of chemotherapy. We therefore need to modify our screening methods to increase the effectiveness of detection of cardiac dysfunction prior to clinical manifestation.
