BACKGROUND: Recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) is a glycoprotein that has been approved by the FDA for the treatment of neutropenia and leukemia in combination with chemotherapies. Recombinant hGM-CSF is produced industrially using the baker's yeast, Saccharomyces cerevisiae, by large-scale fermentation. The methylotrophic yeast, Pichia pastoris, has emerged as an alternative host cell system due to its shorter and less immunogenic glycosylation pattern together with higher cell density growth and higher secreted protein yield than S...

BACKGROUND: Deletion of chromosome 17p (del[17p]) in patients with chronic lymphocytic leukaemia confers very poor prognosis when treated with standard chemo-immunotherapy. Venetoclax is an oral small-molecule BCL2 inhibitor that induces chronic lymphocytic leukaemia cell apoptosis. In a previous first-in-human study of venetoclax, 77% of patients with relapsed or refractory chronic lymphocytic leukaemia achieved an overall response. Here we aimed to assess the activity and safety of venetoclax monotherapy in patients with relapsed or refractory del(17p) chronic lymphocytic leukaemia...

OBJECTIVES: Lyme borreliosis (LB) is the most common human tick-borne infection in Europe and the USA. In this study we set out to analyse the outcome of patients treated for Lyme disease via outpatient parenteral antibiotic therapy (OPAT) and the appropriateness of this treatment using current guidelines. METHODS: This was a retrospective review of all patients with suspected LB managed via OPAT in Glasgow in 2000-11. RESULTS: Of 72 patients treated for suspected LB, 35 patients (49%) were treated in accordance with guidelines and 36 (50%) were treated with no specific guidelines...

Childhood cancers are treated with myelotoxic chemotherapy. Resultant neutropenia can lead to life-threatening infections. There is no consistent guidance on infection control precautions for neutropenic patients who are not yet febrile or infected. Although it is not possible to eradicate infection risk, it is conceivable that the risk could be reduced by effective infection prevention. This study compared infection control measures advised to pediatric and adolescent oncology patients receiving chemotherapy in 2 centers (Cape Town, South Africa, and Newcastle, UK)...

Chemotherapy with taxanes has recently become part of the treatment for many advanced neoplastic diseases, specially breast and lung cancer. Their main noncutaneous adverse reactions include neutropenia and mucositis, which eventually lead to drug discontinuation. Cutaneous adverse reactions are frequent and significantly interfere with the patient's quality of life. Treatments are poorly effective, but special recommendations may improve symptoms and prevent relapses requiring drug rechallenge.

INTRODUCTION: Clozapine, a poorly tolerated antipsychotic drug, is widely recognized as the only efficacious option in treatment-resistant psychosis. The United Kingdom (U.K.) National Institute of Clinical Excellence (NICE) guidance for its consideration defined a threshold for treatment resistance substantially more liberal than that utilized in seminal studies of efficacy. This study documented adherence to NICE guidance in a patient group likely to be enriched for treatment resistance: 150 consecutive assertive outreach and former rehabilitation inpatients...

BACKGROUND: This is an updated version of the original review published in Issue 4, 2004. The use of concurrent chemotherapy and radiotherapy in non-small cell lung cancer (NSCLC) might be seen as a way of increasing the effectiveness of radical radiotherapy at the same time as reducing the risks of metastatic disease. OBJECTIVES: To determine the effectiveness of concurrent chemoradiotherapy as compared to radiotherapy alone with regard to overall survival, tumour control and treatment-related morbidity...

Excessive vancomycin usage has contributed to the emergence of vancomycin-resistant enterococci, and a high vancomycin minimal inhibitory concentration (MIC) >1.0 microg/mL has been associated with poor outcome in patients with meticillin-resistant Staphylococcus aureus (MRSA) infection. In view of these limitations, there is a need for an alternative agent. We evaluated the clinical efficacy and safety of daptomycin given as an alternative agent in the treatment of Gram-positive catheter-related bloodstream infections (CRBSIs) in cancer patients...

Hairy cell leukemia (HCL) is a rare, chronic, B-cell, lymphoproliferative disorder. Treatment has been revolutionized by the advent of interferon (IFN)-alpha and purine analogs (PA). First-line therapy with PA yields complete response rates of 75-100%, with many long-lasting remissions. In the event of profound neutropenia and/or infectious complications, a short sequence of IFN-alpha may precede PA treatment. Because of the excellent results achieved with PA therapy, the potential role of rituximab (an anti-CD20 monoclonal antibody that is highly effective against most B-cell lymphomas) in HCL has yet to be elucidated...

BACKGROUND: We aimed to compare chest low-dose computed tomography (LDCT) with chest radiography (CXR) in the assessment of febrile acute myeloid leukaemia neutropenic patients. METHODS: A prospective non-randomized study was carried out between 30 May, 2003 and 3 June, 2004 in consecutive neutropenic patients who required imaging of the thorax and were treated for acute myeloid leukaemia. Each patient had a baseline 2-view chest radiograph followed by LDCT. Both the CXR and the LDCT studies were blindly and independently reviewed by two chest radiologists...

BACKGROUND: In view of the recent trend toward monotherapy in the treatment of febrile neutropenia, we evaluated the clinical efficacy and safety of imipenem-cilastatin versus piperacillin-tazobactam as an empiric therapy for febrile neutropenia in children with malignant diseases. METHODS: Febrile neutropenic patients received either imipenem-cilastatin or piperacillin-tazobactam randomly. Improvement without any changes in the initial antibiotic treatment was defined as "success" and improvement with modification of the initial treatment and death was defined as "failure"...

OBJECTIVE: Nursing in 'live islands' and routine high dose intravenous immunoglobulins after allogeneic hematopoietic stem cell transplantation were abandoned by many teams in view of limited evidence and high costs. METHODS: This retrospective single-center study examines the impact of change from nursing in 'live islands' to care in single rooms (SR) and from high dose to targeted intravenous immunoglobulins (IVIG) on mortality and infection rate of adult patients receiving an allogeneic stem cell or bone marrow transplantation in two steps and three time cohorts (1993-1997, 1997-2000, 2000-2003)...

BACKGROUND: Since the late 1990s there has been increasing demand for donated granulocyte transfusions to treat or prevent severe infections in patients who lack their own functional granulocytes. Other than in neonates, no systematic reviews have been performed for over 10 years relating to the efficacy of prophylactic granulocyte transfusions. OBJECTIVES: To determine the effectiveness and safety of granulocyte transfusions compared with a control population not receiving this intervention for preventing mortality due to infection or due to any other cause in patients with neutropenia or disorders of neutrophil function...

AIM: A large variety of adverse reactions are well known to frequently occur during chemotherapy and radiotherapy in oncology. Specific medications exist to target individual side effects. The aim of this study was to explore in a pilot trial whether supplementation with French maritime pine bark extract Pycnogenol could alleviate side effects and improve patient's quality of life. METHODS: Cancer patients who previously underwent surgery and who were in view of their pathology in relatively good condition, both physically and psychologically, were recruited for this study and divided into two groups...
