Abstract
OBJECTIVE The aim of this study was to investigate the data of HSCT patients who were admitted to our Hematology ICU due to infections or infectious complications. MATERIALS AND METHODS HSCT patients who were admitted to our Hematology ICU between 01 January 2014 and 01 September 2017 were analyzed retrospectively. RESULTS 62 HSCT patients were included in this study. The median age was 55.5 years and 58% of the patients were allogeneic HSCT patients. Major underlying hematologic disorders were multiple myeloma (29%) and lymphoma (27.4%). The most common reasons for ICU admission were sepsis/septic shock (61.3%) and acute respiratory failure (54.8%). Overall ICU mortality rate was 45.2%. However, a lot of factors were related with ICU mortality of HSCT patients in univariate analysis, only APACHE II score was found to be an independent risk factor for ICU mortality. While there was infection in 58 patients at ICU admission, new infections developed in 38 patients during ICU stay. The most common new infection was pneumonia/VAP, while the most frequently isolated bacteria were Acinetobacter baumannii. Length of ICU stay, sepsis/septic shock as a reason for ICU admission and the presence of urinary catheter at ICU admission were determined factors for ICU-acquired infections. There was no difference between autologous and allogeneic stem cell transplant patients in terms of ICU morbidities and mortality. However, pneumonia/VAP developed in the ICU was higher in autologous HSCT patients, while bloodstream/catheter-related bloodstream infection was higher in allogeneic HSCT patients. CONCLUSION It was concluded that early or late post-HSCT infections and related complications (sepsis, organ failure, etc.) constituted a major part of the reasons for ICU admission, ICU mortality and ICU morbidities.

Abstract
BACKGROUND Escherichia coli (E. coli) is a pathogen of great concern in immunosuppressed patients. While antimicrobial prophylactic therapy has become the standard, the emergence of resistant pathogens has some questioning its use. This study describes our experience with E.coli as a pathogen in neutropenic patients with a hematologic malignancy, and addresses future directions of treatment for this patient population. METHODS A retrospective chart review of 245 E.coli bacteremia patients at Moffitt Cancer Center from 05/18/02 - 05/15/12 was conducted. Out of 245 patients, 169 did not meet the criteria due to non-neutropenic status, or not diagnosed with a hematologic malignancy, or due to having insufficient medical records. Thus, they were excluded from the study. As a result, 76 patients were involved in this study. Patients were identified via microbiology laboratory computerized records. RESULTS The included patients experienced clinically significant E.coli bacteremia resulting in a median hospital stay of 14.7 days. Several patients developed severe sepsis requiring the use of pressor and ventilator therapy. CONCLUSIONS E.coli is a major pathogen in these patient populations resulting in extended hospital stays and specialized treatment to overcome their E.coli bacteremia. The data supports the use of fluoroquinolone prophylactic therapy, however, earlier detection and treatment of neutropenic infection is needed.

Abstract
BACKGROUND Influenza infection is a potential cause of severe morbidity in children with cancer; therefore vaccination against influenza is recommended. However, data are conflicting regarding the immune response to influenza vaccination in children with cancer, and the value of vaccination remains unclear. OBJECTIVES 1. To assess the efficacy of influenza vaccination in stimulating an immunological response in children with cancer during chemotherapy, compared with control groups.2. To assess the efficacy of influenza vaccination in preventing confirmed influenza and influenza-like illness and/or in stimulating immunological response in children with cancer treated with chemotherapy, compared with placebo, no intervention or different dosage schedules.3. To identify the adverse effects associated with influenza vaccines in children with cancer treated with chemotherapy, compared with other control groups. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (1966 to 2012) and EMBASE (1980 to 2012) up to August 2012. We also searched reference lists of relevant articles and conference proceedings of the Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), the Infectious Diseases Society of America (IDSA), the Multinational Association of Supportive Care in Cancer (MASCC) and the International Society of Paediatric Oncology (SIOP). SELECTION CRITERIA We considered randomised controlled trials (RCTs) and controlled clinical trials (CCTs) in which the serological response to influenza vaccination of children with cancer was compared with that of control groups. We also considered RCTs and CCTs that compared the effects of influenza vaccination on clinical response and/or immunological response in children with cancer being treated with chemotherapy, compared with placebo, no intervention or different dosage schedules. DATA COLLECTION AND ANALYSIS Two independent review authors assessed the methodological quality of included studies and extracted the data. MAIN RESULTS We included 1 RCT and 9 CCTs (total number of participants = 770). None of the included studies reported clinical outcomes. All included studies reported on influenza immunity and adverse reactions to vaccination. In five studies, immune responses to influenza vaccine were compared in 272 children receiving chemotherapy and 166 children not receiving chemotherapy. In four studies, responses to influenza vaccine were assessed in 236 children receiving chemotherapy compared with responses in 142 healthy children. Measures used to assess immune responses included a four-fold rise in antibody titre after vaccination, development of a haemagglutination inhibition (HI) titre > 32 and pre- and post-vaccination geometric mean titres (GMTs). Immune responses in children receiving chemotherapy were consistently weaker (four-fold rise of 38% to 65%) than those in children who had completed chemotherapy (50% to 86%) and in healthy children (53% to 89%). In terms of adverse effects, 391 paediatric oncology patients received influenza vaccine, and the adverse effects described included mild local reactions and low-grade fever. No life-threatening or persistent adverse effects were reported. AUTHORS' CONCLUSIONS Paediatric oncology patients receiving chemotherapy are able to generate an immune response to the influenza vaccine, but it remains unclear whether this immune response protects them from influenza infection or its complications. We are awaiting results from well-designed RCTs addressing the clinical benefit of influenza vaccination in these patients.

Abstract
A literature review was conducted to ascertain the prognosis of patients with haematological malignancies admitted to the intensive care unit (ICU) and to identify any factors that could be shown to influence outcome. Studies that examined outcomes among patients with haematological malignancy admitted to ICU were evaluated. Pooled outcome data relating to ICU, hospital and six-month mortality were compiled. A qualitative assessment of the evidence relating to putative determinants of prognosis was made. Observational studies examining outcomes among over 10,000 haematological malignancy patients admitted to the ICU were identified. Approximately 40% of such patients survived until hospital discharge. The principle determinants of short-term survival would appear to be related to the severity of the acute illness and the consequent physiological derangement or organ system dysfunction. In the longer term, factors relating to the prognosis of the underlying malignancy appear to be important.

Abstract
INTRODUCTION About 15% of patients with haematological malignancy develop acute respiratory failure (ARF), necessitating admission to intensive care where their mortality is of the order of 50%. STATE OF THE ART The prognosis of these patients is not determined by the pathological characteristics of the malignancy but by the cause of the acute respiratory failure. In effect, the need to resort to mechanical ventilation in the presence of dysfunction of other organs dominates the prognosis. Even if the use of non-invasive ventilation in these patients has reduced the need for intubation and reduced the mortality, its prolonged use in the most severely affected patients prevents the optimal diagnostic and therapeutic management. PERSPECTIVES Fibreoptic bronchoscopy with broncho-alveolar lavage (BAL) is considered the cornerstone of aetiological diagnosis but its diagnostic effectiveness is poor, at best 50%, and this has led to increasing interest in high resolution CT scanning and regularly reawakens a transitory enthusiasm for surgical lung biopsy. Furthermore, in hypoxaemic patients, fibreoptic bronchoscopy with BAL may be the origin of the resort to mechanical ventilation, and thus increased mortality. The place of recently developed non-invasive tools is under evaluation. In effect, though the individual performance of diagnostic molecular techniques on sputum, blood, urine or naso- pharyngeal secretions has been established, the combination of these tools as an alternative to BAL has not yet been reported. CONCLUSION This review deals with acute respiratory failure in patients with haematological malignancy. It includes a review of the recent literature and considers the current controversies, in particular the risk-benefit balance of fibreoptic bronchoscopy with BAL in severely hypoxaemic patients.

Abstract
BACKGROUND AND OBJECTIVE Multi-resistant coagulase-negative staphylococci (CNS) may cause systemic infections in patients undergoing bone marrow transplantation. Daptomycin, a new lipopeptide, and tigecycline, a new glycylcycline, have excellent activity against Gram-positive bacteria including methicillin-resistant staphylococci. This study presents the in vitro activity of daptomycin and tigecycline compared to vancomycin and fosfomycin against 105 CNS isolated from 76 bone marrow transplant patients with symptomatic bacteremia. MATERIAL AND METHODS Blood stream isolates of Staphylococcus epidermidis (n = 102) and Staphylococcus haemolyticus (n = 3) from bone marrow transplant patients were collected from 2000 to 2006. The susceptibility of all isolates was tested using methods of the Clinical Laboratory Standards Institute. RESULTS The minimal inhibitory concentrations MIC(50) and MIC(90) were 0.125 microg/mL and 0.25 microg/mL for daptomycin, 0.25 and 0.5 microg/mL for tigecycline, 1 microg/mL and 2 microg/mL for vancomycin, and 8 microg/mL and >256 microg/mL for fosfomycin, respectively. MIC values of tested agents were similar for both methicillin-sensitive and methicillin-resistant S. epidermidis strains. CONCLUSIONS All CNS isolates were susceptible to the new antistaphylococcal agents daptomycin and tigecycline. Although vancomycin had been used over the past 30 yr at our bone marrow transplant unit all CNS were still susceptible to vancomycin.

Abstract
Hematopoietic stem cell transplantation (HSCT) is being used increasingly in the treatment of malignant and nonmalignant diseases. The treatment modality has been proven effective but is not without risks. Studies consistently have identified the need for advanced supportive care (e.g., multiple organ dysfunction, vasopressor use, mechanical ventilation) as a negative prognostic indicator in patients who have received HSCT. Among patients who have received HSCT, 15%-40% require critical care monitoring or advanced support. Nurses on intensive care units can positively impact outcomes for transplant recipients when they possess the specialized skills to recognize and promptly intervene when transplant-related complications arise. This article will provide a basic overview of the HSCT process and outline the complications that may necessitate transfer to a higher level of care for specialized skills and equipment in the intensive care setting.

Abstract
Bone marrow transplantation for lysosomal storage disorders has been used for the past 25 years. The early allure of a promising new therapy has given way to more realistic expectations, as it has become clear that bone marrow transplantation is not a cure, but merely ameliorates the clinical phenotype. The results in some disorders are more acceptable than in others. Significant challenges have emerged, particularly the poor mesenchymal and neurological responses. Important recent advances in lysosomal biology, both in health and disease, have helped us to better understand the results of bone marrow transplantation, and to rationalize its role in the treatment of lysosomal storage disorders alongside newer therapies. At the same time, they have helped researchers to explore new therapeutic applications of bone marrow cells, such as gene and stem cell therapy.

Abstract
OBJECTIVE Nearly 15% of cancer patients experience acute respiratory failure (ARF) requiring admission to the intensive care unit, where their mortality is about 50%. This review focuses on ARF in cancer patients. The most recent literature is reviewed, and emphasis is placed on current controversies, most notably the risk/benefit ratio of fiberoptic bronchoscopy and BAL in patients with severe hypoxemia. BACKGROUND Fiberoptic bronchoscopy with bronchoalveolar lavage (BAL) is the cornerstone of the causal diagnosis. However, the low diagnostic yield of about 50%, related to the widespread use of broad-spectrum antimicrobial therapy in cancer patients, has generated interest in high-resolution computed tomography (HRCT) and primary surgical lung biopsy. In patients with hypoxemia, bronchoscopy and BAL may trigger a need for invasive mechanical ventilation, thus considerably decreasing the chances of survival. DISCUSSION The place for recently developed, effective, noninvasive diagnostic tools (tests on sputum, blood, urine, and nasopharyngeal aspirates) needs to be determined. The prognosis is not markedly influenced by cancer characteristics; it is determined chiefly by the cause of ARF, need for mechanical ventilation, and presence of other organ failures. Although noninvasive ventilation reduces the need for endotracheal intubation and diminishes mortality rate, its prolonged use in patients with severe disease may preclude optimal diagnostic and therapeutic management. The appropriateness of switching to endotracheal mechanical ventilation in patients who fail noninvasive ventilation warrants evaluation. CONCLUSION This review discusses risks and benefits from invasive and non invasive diagnostic and therapeutic strategies in critically ill cancer patients with acute respiratory failure. Avenues for research are also suggested in order to improve survival in these very high risk patients.

Abstract
The mortality rate associated with respiratory failure due to invasive fungal infections after allogeneic hematopoietic stem cell transplantation (HSCT) is exceedingly high. We present a retrospective analysis of 4 HSCT recipients who survived long-term artificial respiration subsequent to pulmonary mycosis, and compare our current findings with historic data. Several clinical parameters indicate a remarkable improvement in the clinical courses of those patients in recent years: weaning time, extubation rate, and improvement of additional organ failures were all significantly better in patients treated after the emergence of new antimycotic agents, resulting in prolonged overall survival. We propose that our observations reflect an improved management of these patients, mainly because of the use of new antimycotics with alternative mechanisms of action and decreased toxicity, allowing for earlier, more aggressive, and more effective antifungal treatment approaches. In addition, the optimized use of new technologies designed to augment spontaneous breathing efforts by patients, mechanical ventilation, as well as the advantages of early tracheotomy will contribute to better outcomes in the treatment of respiratory failure due to pulmonary mycoses following allogeneic HSCT.

Abstract
Pulmonary mycoses count among the most dangerous complications in allogeneic hematopoietic stem cell transplantation. Despite the establishment of antifungal chemoprophylaxis and empirical antifungal treatment, they frequently lead to respiratory failure and are still associated with an extraordinarily poor prognosis. However, the emergence of new antimycotics with alternative mechanisms of actions and decreased toxicity in combination with the development of new non culture-based diagnostic techniques may allow earlier, more aggressive and more effective antifungal treatment approaches. In addition, the optimized use of new technologies designed to augment spontaneous breathing efforts by patients, mechanical ventilation, as well as the advantages of early tracheostomy lead us to expect better outcomes in the treatment of respiratory failure due to pulmonary mycoses following allogeneic hematopoietic stem cell transplantation.

Abstract
Despite impressive accomplishments in supportive care over the past decade, infections with a diverse group of microorganisms remain leading causes of morbidity and mortality after hematopoietic stem cell transplantation. The epidemiology of infectious complications has shifted substantially in the past decade with changes in antimicrobial prophylaxis, conditioning regimens, and graft manipulation, such that invasive mould infections and late viral infections are now the overriding concerns. Individual patient risk for infections is predicated on multiple disease-specific, patient-specific, and transplant-related factors but often tracks with the cumulative level of immunosuppression (such as dose of corticosteroids used for the treatment of graft vs host disease [GVHD]). New antivirals and antifungals have entered clinical practice and hold considerable promise for improved outcomes.

Abstract
BACKGROUND Perioperative and intensive therapy unit (ITU) morbidity and mortality has remained unchanged during the past several decades, and this at an unacceptably high level. It is most likely, in the EU countries annually, that more than 1 million people suffer severe sepsis and some 300,000 die. Pharmaceutical attempts at prevention and treatment have, despite extensive efforts, hitherto failed to improve outcome more significantly. Much supports the fact that sepsis and its severe consequences are results of a malfunctioning innate immune system, impaired by both lifestyle and disease. A series of mostly simple measures to prevent further deterioration of the immune system, and to boost it, is recommended. Among the measures recommended are some modifications of surgical and postoperative management: restricted use of antibiotics, attempts made to maintain salivation and GI secretions, omission of prophylactic gastric decompression, postoperative drainage and preoperative bowel preparation, restricted use of stored blood, avoidance of overload with nutrients, uninterrupted enteral nutrition but also tight blood glucose control, supply of antioxidants, administration of prebiotic fibre and probiotic lactic acid bacteria. Nutritional control of postoperative morbidity includes use of so-called synbiotics, e.g. a combination of bioactive lactic acid bacteria (LAB) and bioactive plant fibres. RESULTS Dramatic reduction in (in reality, almost abolishment of) septic morbidity is reported following supplementation of specific bioactive lactic bacteria in combination with prebiotic plant fibres, as tried in controlled studies in connection with extensive abdominal operations, liver transplantation and severe acute pancreatitis.

Abstract
OBJECTIVE To identify predictors of 30-day mortality in critically ill cancer patients with septic shock. DESIGN Retrospective study over a 6-year period. SETTING Twelve-bed medical intensive care unit (ICU). PATIENTS Eighty-eight patients (55 men, 33 women) aged 55 (43.5-63) years admitted to the ICU for septic shock. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Eighty (90.9%) patients had hematological malignancies and eight (9.1%) had solid tumors; 47 patients (53.4%) were neutropenic, 19 (21.6%) were hematopoietic stem cell transplantation (HSCT) recipients, and 27 (30.7%) were in remission. Microbiologically documented infections were found in 60 (68.2%) patients. The Simplified Acute Physiologic Score II (SAPS II) and Logistic Organ Dysfunction (LOD) scores at ICU admission were 66 (47-89) and 7 (5-10), respectively, and the LOD score on day 3 was 8 (4-10). Sixty-eight (78.1%) patients received invasive mechanical ventilation (MV), 12 (13.6%) noninvasive MV, 22 (25%) dialysis. Thirty-day mortality was 65.5% (57/88). By multivariable analysis, mortality was higher when time to antibiotic treatment was >2 h [odds ratio (OR), 7.05; 95% confidence interval (95% CI), 1.17-42.21] and when DLOD (day 3-day 1 LOD score/day 3 LOD score) was high (OR, 3.47; 95% CI, 1.44-8.39); mortality was lower when admission occurred between 1998 and 2000 (OR, 0.23; 95% CI, 0.05-0.98) and when initial antibiotics were adapted (OR, 0.24; 95% CI, 0.06-0.09). CONCLUSIONS Earlier ICU admission and antibiotic treatment of critically ill cancer patients with septic shock is associated with higher 30-day survival. The LOD score change on day 3 as compared to admission is useful for predicting survival.

Abstract
Patients with myasthenia gravis (MG) who do not respond to conventional immunotherapeutic agents, or cannot tolerate their side effects, are considered "refractory." Ablation of the immune system followed by bone marrow transplant has been shown to cure experimental MG in rats. It is now known that immunoablative treatment with high-dose cyclophosphamide does not damage hematopoietic "stem cells," permitting repopulation of the immune system without bone marrow transplant. Recent evidence indicates that this treatment can induce durable remissions in autoimmune diseases. We treated three myasthenic patients, for whom treatment with thymectomy, plasmapheresis, and conventional immunotherapeutic agents failed, by using high-dose cyclophosphamide (50mg/kg/day intravenously for 4 days) followed by granulocyte colony stimulating factor. All three patients tolerated the treatment well and have had marked improvement in myasthenic weakness, permitting reduction of immunosuppressive medication to minimal levels. Acetylcholine receptor (AChR) antibody levels decreased in two AChR antibody-positive patients, and anti-MuSK antibody levels decreased in one "AChR antibody-negative" patient. The patients have been followed for up to 3.5 years, with no recurrence of symptoms. High-dose cyclophosphamide treatment appears to be an effective and safe treatment for selected patients with refractory MG. Further follow-up of these and additional patients will be needed to determine whether the benefit is durable.
