The diagnosis of invasive pulmonary aspergillosis (IPA) is still in challenge in clinical practice, particularly for those patients without an obvious neutropaenia. In this study, a well-validated qPCR method and Platelia galactomannan (GM) assay were compared for their diagnostic performance using paired samples of bronchoalveolar lavage (BAL) fluid and serum from predominantly non-neutropaenic patients. In the serum samples, qPCR showed a comparable performance with GM assay in terms of sensitivity and specificity...

BACKGROUND: The absolute neutrophil count (ANC) is currently used to assess immune status of patients on cytotoxic therapy. The CD4 lymphocytes have also been shown to be of importance in protection against opportunistic infections. In people of African descent a low baseline ANC has been recorded and the currently accepted neutropaenic threshold may not be appropriate. OBJECTIVE: This study was aimed at comparing the change in ANC to CD4 lymphocyte count in adult cancer patients following chemotherapy...

BACKGROUND: Neutropaenic patients are at a high risk of contracting severe infections. In particular, in these patients, parameters with a high negative predictive value are desirable for excluding infection or bacteraemia. This study evaluated sepsis biomarkers in neutropaenic patients suffering from systemic inflammatory response syndrome (SIRS). Further, the predictive capacities of evaluated biomarkers in neutropaenic SIRS patients were compared to non-neutropaenic SIRS patients. MATERIAL AND METHODS: In this prospective observational cohort study, patients with clinically suspected sepsis were screened...

Septic shock (SS) at the onset of febrile neutropaenia (FN) is an emergency situation that is associated with high morbidity and mortality. The impact of the specific aetiology of bloodstream infections (BSIs) in the development of SS at the time of FN is not well established. The aim of this study was to evaluate the association between the aetiology of BSIs and SS at the time of FN in hospitalised adult cancer patients. This prospective cohort study was performed at a single tertiary hospital from October 2009 to August 2011...

BACKGROUND: The vascular disrupting agent ombrabulin shows synergy with docetaxel in vivo. Recommended phase II doses were determined in a dose escalation study in advanced solid tumours. METHODS: Ombrabulin (30-min infusion, day 1) followed by docetaxel (1-h infusion, day 2) every 3 weeks was explored. Ombrabulin was escalated from 11.5 to 42 mg m(-2) with 75 mg m(-2) docetaxel, then from 30 to 35 mg m(-2) with 100 mg m(-2) docetaxel. Recommended phase II dose cohorts were expanded...

We report the case of a 27-month-old male with an unusual complication of aplastic anaemia and neutropenic enterocolitis. He suffered persistent neutropaenic sepsis and clinical deterioration forced the strategy of matched sibling haematopoietic stem cell transplantation. With engraftment and clinical recovery post-transplant, enteral feeding was re-established. Despite continued improvement the child began to vomit faeculent stomach content. Barium swallow showed gastro-colic and gastro-enteric fistulisation with contrast passing directly from stomach into descending colon and directly into jejunum...

In this study we sought to determine the contribution of microbial translocation to febrile episodes with no attributable microbiological cause (Fever of Unknown Origin, FUO) in an adult febrile neutropaenic cohort. Endotoxin concentrations were measured with the chromogenic Limulus Amoebocyte Assay and used as a direct measure of bacterial products whilst soluble CD14 (sCD14), measured with ELISA was selected as an indicator of the early host response to endotoxins. Endotoxin concentrations in this cohort were generally elevated but did not differ with the presentation of fever...

PURPOSE: Paired blood cultures, drawn from the catheter and a peripheral vein, used for calculation of the differential time to positivity (DTP), have been proposed for the detection of catheter-related bloodstream infections (CRBSIs). The most relevant catheter lumen to be sampled in multi-lumen central venous catheters (CVCs) has not been recommended. METHODS: Forty-four febrile neutropaenic patients, following haematopoietic stem cell transplantation (HSCT) and with multi-lumen CVCs in place, were investigated using the DTP method of blood samples drawn from every lumen of the CVC and a peripheral vein...

We examined the performance of a real-time polymerase chain reaction (PCR) test (SeptiFast) for early detection of bloodstream infection in febrile neutropaenic patients. Blood samples from 201 patients were screened for pathogens by blood culture and by PCR on the first day of fever. PCR results were available earlier (median 3 days for bacteria, 5 days fungal pathogens; P ≤ 0.01). The sensitivity (0.74) and specificity (0.96) of the PCR test were acceptable for Gram negatives when culture was considered the gold standard, but sensitivity of the test was poorer for Gram-positive organisms (0...

BACKGROUND: Mannose-binding Lectin protein (MBL) has been suggested to be relevant in the defence against infections in immunosuppressed individuals. In a Swedish adult cohort immunosuppressed from both the underlying disease and from iatrogenic treatments for their underlying disease we investigated the role of MBL in susceptibility to infection. METHODS: In this cross sectional, prospective study, blood samples obtained from 96 neutropaenic febrile episodes, representing 82 individuals were analysed for single nucleotide polymorphism (SNP) in the MBL2 gene...

BACKGROUND: Neonates have immature granulopoiesis, which frequently results in neutropenia after sepsis. Neutropaenic septic neonates have a higher mortality than non-neutropenic septic neonates. Therefore, granulocyte transfusion to septic neutropenic neonates may improve outcomes. OBJECTIVES: The primary objective was to determine the effect of granulocyte or buffy coat transfusions as adjuncts to antibiotics, after confirmed or suspected sepsis in neutropenic neonates, on all-cause mortality during hospital stay and neurological outcome at ≥ year of age...

The purpose of this investigation was to describe the characteristics of the use of systemic antifungal agents (AFAs) and to evaluate their appropriateness of use. A prospective drug-utilisation study was conducted in intensive-care areas: haematology-oncology services and transplant units. Data were collected in three periods over 9 months. The required sample size was determined to be 113 patients (margin of error ±7%, 95% confidence interval [CI]), assuming a variability of 50%. Two different investigator groups evaluated the appropriateness of use separately; Cohen's Kappa index was used to calculate the degree of agreement between groups...

Invasive Candida infections are recognised as a cause of increased morbidity and mortality in intensive care patients, particularly those with recent extensive gastroabdominal surgery. Due to the difficulties of diagnosis, several authors have analysed risk factors suggestive of invasive candidiasis to identify patients at highest risk. Such patients may be potential candidates for preemptive antifungal therapy before becoming seriously ill. The extent of body site colonisation due to Candida species was recognised to be related with consequent invasive disease...

The aim of this study was to evaluate the pharmacokinetics and efficacy of posaconazole (PSC) in combination with granulocyte colony-stimulating factor (G-CSF) in a neutropaenic murine model of disseminated zygomycosis (mucormycosis) due to Rhizopus microsporus. Male BALB/c mice were rendered neutropaenic with cyclophosphamide (200 mg kg(-1), intraperitoneally) administered on days -1 and +5 postinfection. Mice were infected with R. microsporus (5 × 10(4) spores ml(-1)) intravenously. Mice were treated with PSC (40 mg kg(-1) day(-1) by gavage) or G-CSF (300 μg kg(-1) day(-1) subcutaneously) or with the combination of PSC and G-CSF...
