    Notes: Abstract  The influence of underlying disease on documented infections has rarely been addressed in patients treated with high-dose chemotherapy (HDCT) and subsequent autologous peripheral blood stem cell transplantation (PBSCT). Because autografting has been used most frequently for malignant lymphomas and breast cancer, we analyzed in a retrospective study the data of 100 consecutive adult patients with either malignant lymphomas (group A, n=50) or breast cancer (group B, n=50) treated with HDCT at a single institution. The number of autografted CD34+ cells was not statistically different in either group. In this paper, we show for the first time that there is a significant difference in clinically or microbiologically documented infections in these groups of patients: documented infections occurred in 30% of malignant lymphoma patients but only in 4% of breast cancer patients (P=0.001). Of all isolated microorganisms, 78% were gram-positive. Because most of the documented infections were due to staphylococci, further studies should prospectively evaluate preventive measures to reduce the high incidence of these infections. This is especially important for lymphoma patients, who can be regarded as a high-risk group concerning gram-positive bacteremia.

    Notes: Summary An 18-year-old woman was admitted to hospital because of subcutaneous hematoma and fever of unknown origin. Acute myeloid leukemia was diagnosed and empirical antimicrobial treatment and induction chemotherapy were started. After initial defervescence, fever relapsed 21 days after the onset of neutropenia. The CT scan of the lung was consistent with an invasive fungal infection. Treatment with amphotericin B was started and antimicrobial treatment was continued with liposomal amphotericin B because of an increase in creatinine later. The fever persisted and the patient suddenly developed progressive neurological symptoms. CT scan of the head suggested cerebral infarction and angiography of the extra- and intracranial arteries showed signs of vasculitis. Six days after the onset of neurological symptoms cerebral death was diagnosed. Autopsy revealed non-septate, irregularly branched hyphae in various histologic sections including brain. Absidia corymbifera could be isolated from lung tissue confirming the diagnosis of disseminated mucormycosis. In this case, angiographic findings suggested severe cerebral vasculitis which was in fact caused by thromboembolic dissemination of fungal hyphae. This case underlines the fact that cerebral symptoms in febrile neutropenic patients are highly indicative for fungal infections of the brain.
