Bone marrow examination (BME) represents an essential tool for diagnosis and monitoring of haematological disorders. It remains associated with morbidity and discomfort; repeat examinations are frequent. We made a single-centre prospective survey on 700 BME between July 2007 and July 2008 with a structured anonymized questionnaire for patients undergoing and physicians performing BME, which includes at our institution always aspiration and trephine. All procedures were performed according to institutionalised standard operating procedures; 412 patients' (58.9%) and 554 physicians' (79.1%) questionnaires were returned. Pain was the only procedure-related complication; no pain was reported in 149 (36.7%), bearable pain in 242 (59.6%) and unbearable pain in 15 (3.7%) cases. Premedication associated complications were reported by 110 (32.7%) of the 336 (65.4%) patients with premedication before BME. None of these were > WHO grade 2; most frequently reported were tiredness (76 patients; 22.6%), dizziness (19 patients; 5.7%) and nausea (15 patients; 4.5%). Only two factors were significantly associated with unbearable pain: "pain during prior BME" (seven of 94 with versus one of 198 without previous pain; p < 0.01) and "information before BME" (four of 11 without versus 12 of 372 with adequate information before BME; p < 0.01). Inadequate information at any time showed a trend towards an association with unbearable pain (p = 0.08). No other factor was associated with unbearable pain. Good and adequate information appears to be the best way to reduce pain, even for a future BME.

The aim of this study was to assess the frequency of potential drug-drug interactions (pDDIs) and adverse drug events (ADEs) associated with antimycotics in hospitalized patients with hematopoietic SCT (HSCT). Of the 120 HSCT recipients evaluated, 36 received antimycotics. A total of 124 ADEs were recorded in 32 of the 36 patients treated, with 54 ADEs being possibly and 9 probably related to antimycotics. Of the treatments with amphotericin B, 93% were associated with one or more possible and 36% with probable ADEs. The corresponding figures for lipid-based amphotericin B were 100% and 7%, for voriconazole 68% and 11% and for caspofungin 70% and 0%. A total of 57 potentially severe DDIs associated with antimycotics were detected in 31 of the 36 patients. Of these, 14 DDIs were a possible cause of an ADE and 5 (4 times a combination of voriconazole with CYA and once a combination of CYA with conventional amphotericin B) were probably related. Although the prevalence of pDDIs and ADEs is high in HSCT patients, ADEs related with a high probability to treatment with antimycotics are rare. Regarding the high prevalence of pDDIs, our findings underscore the importance of close monitoring of laboratory and clinical parameters, as well as dose adjustment for critical drugs, in patients with HSCT.

Induction/consolidation chemotherapy and allogeneic hematopoietic stem cell transplantation (HSCT) for hematological malignancies are associated with treatment-related risks such as infections. The predominant types of infections are blood stream infections (BSIs) and respiratory tract infections. We prospectively compared infectious complications after induction/consolidation chemotherapy versus allogeneic HSCT in a directly comparable setting with both groups being hospitalized on the same ward. From July 2003 until June 2008, 492 hospitalizations of 321 patients took place; 237 chemotherapies and 255 HSCTs were performed. We observed 49 (20.7%) BSIs, 70 (29.5%) pneumonias and 11 (4.6%) probable or proven invasive mould infections in the chemotherapy group. In the HSCT group we detected 70 (27.5%) BSIs, 71 (27.8%) pneumonias and 14 (5.4%) probable or proven invasive mould infections. There was a trend toward more transfers to the intensive care unit (OR 1.61; 95%CI 0.95-2.72; P ¼ 0.074) and BSIs (OR 1.45; 95%CI 0.95-2.22; P ¼ 0.079) after HSCT; 44 (13.7%) patients died. In-hospital mortality was significantly higher in the HSCT group (OR 2.39; 95%CI 1.22-4.68; P ¼ 0.010). We conclude that the risk of pneumonia and invasive mould infection is comparable after induction/ consolidation chemotherapy and allogeneic HSCT. However, there was a trend for more BSIs and intensive care unit stays and a higher mortality in the latter.

Change from nursing in 'live islands' to SR and reduction of high dose to targeted IVIG did not result in increased infection rates or mortality despite an increase in patient age. These results support the current practice.
