Pranita D Tamma, Jesus Rodriguez-Bano
The continued rise in infections caused by extended-spectrum β-lactamase (ESBL)-producing pathogens is recognized globally as one of the most pressing concerns facing the healthcare community. Carbapenems are widely regarded as the antibiotics of choice for the treatment of ESBL-producing infections, even when in vitro activity to other β-lactams has been demonstrated. However, indiscriminant carbapenem use is not without consequence, and carbapenem overuse has contributed to the emergence of carbapenem-resistant Enterobacteriaceae...

Viral infections have been reported with dasatinib use, but its cytomegalovirus risk after hematopoietic-cell transplantation (HCT) is not known. We found that post-HCT dasatinib use increased the risk of cytomegalovirus reactivation (adjusted hazard ratio 7.65; 95% CI, 1.84-31.7), controlling for acute graft-versus-host disease, in 109 patients with Philadelphia-chromosome-positive malignancies.

Background.: The ability to make early therapeutic decisions when treating invasive aspergillosis using changes in biomarkers as a surrogate for therapeutic response could significantly improve patient outcome. Methods.: Cox proportional hazards model and logistic regression were used to correlate early changes in galactomannan index (GMI) to mortality and overall response, respectively, from patients with positive baseline GMI (≥0.5) and serial GMI during treatment from a phase 3 clinical trial for the treatment of invasive mold disease...

REVIEW
John J Halperin
Although patients with Legionnaire's disease frequently develop alterations of consciousness, this is no more frequent than in patients hospitalized with other, equally severe forms of bacterial pneumonia. Legionella meningitis occurs rarely, if ever. Patients with Legionnaire's are susceptible to critical illness polyneuropathy/myopathy, as are other critically ill patients. Legionnaire's patients may develop MRI hyperdensities in the splenium of the corpus callosum, as may other patients with severe infections...

REVIEW
Abdullah Chahin, Steven M Opal
Severe legionella pneumonia poses a diagnostic challenge and requires early intervention. Legionnaire's disease can have several presenting signs, symptoms, and laboratory abnormalities that suggest that Legionella pneumophila is the pathogen, but none of these are sufficient to distinguish L pneumophila pneumonia from other respiratory pathogens. L pneumophila is primarily an intracellular pathogen and needs treatment with antibiotics that efficiently enter the intracellular space.

Legionnaire's disease (LD) is mainly reported in apparently immunocompetent patients. Among them, risk factors include chronic lung disease and smoking. However, LD is also well reported among immunocompromised patients, particularly those treated with anti-tumor necrosis factor alpha therapy, patients with hematological malignancy, and transplant patients. This article discusses the available data on immunity against Legionella spp, epidemiology, clinical presentation, diagnosis, and treatment of LD in immunocompromised patients...

Bacterial pneumonias exact unacceptable morbidity on patients with cancer. Although the risk is often most pronounced among patients with treatment-induced cytopenias, the numerous contributors to life-threatening pneumonias in cancer populations range from derangements of lung architecture and swallow function to complex immune defects associated with cytotoxic therapies and graft-versus-host disease. These structural and immunologic abnormalities often make the diagnosis of pneumonia challenging in patients with cancer and impact the composition and duration of therapy...

REVIEW
Steven A Pergam
Invasive fungal infections, which occur primarily as a consequence of prolonged neutropenia and immunosuppression, are a life-threatening complication seen among patients with hematologic malignancies. The routine use of triazole antifungal prophylaxis, enhanced diagnostics, and newer antifungal agents have led to improvements in the care of fungal pneumonias, but invasive fungal infections remain a major cause of morbidity and mortality. This article covers risk factors for major fungal infections, diagnostic approaches, and treatment options for specific fungal pathogens, including Aspergillus and Mucorales species, and discusses current approved strategies for prevention of common and uncommon fungal pneumonias...

REVIEW
Margaret L Green
Viral pneumonia is a common complication for patients with hematologic malignancies and after hematopoietic cell transplantation causing significant morbidity, and often mortality. Infections are predominantly caused by herpes viruses, either by reactivation of latent infection, or less commonly primary infection, or community respiratory viruses. High-resolution CT scan is useful for diagnosis but is nonspecific; generally, bronchoalveolar lavage is required. Prevention strategies are not pathogen-specific but include vaccination, chemoprophylaxis, preemptive treatment, and effective infection-prevention strategies during community outbreaks...

BACKGROUND: Drug resistance among gram-negative pathogens is a risk factor for inappropriate empiric treatment (IET), which in turn increases the risk for mortality. We explored the impact of carbapenem-resistant Enterobacteriaceae (CRE) on the risk of IET and of IET on outcomes in patients with Enterobacteriaceae infections. METHODS: We conducted a retrospective cohort study in Premier Perspective database (2009-2013) of 175 US hospitals. We included all adult patients with community-onset culture-positive urinary tract infection (UTI), pneumonia, or sepsis as a principal diagnosis, or as a secondary diagnosis in the setting of respiratory failure, treated with antibiotics within 2 days of admission...

BACKGROUND: Strongyloidiasis is a chronic parasitic infection caused by Strongyloides stercoralis. Severe cases such as, hyperinfection syndrome (HS) and disseminated strongyloidiasis (DS), can involve pulmonary manifestations. These manifestations frequently aid the diagnosis of strongyloidiasis. Here, we present the pulmonary manifestations and radiological findings of severe strongyloidiasis. METHODS: From January 2004 to December 2014, all patients diagnosed with severe strongyloidiasis at the University of the Ryukyus Hospital or affiliated hospitals in Okinawa, Japan, were included in this retrospective study...

Pulmonary mold infections are caused by ubiquitous organisms found in soil, water, and decaying vegetation, including Aspergillus spp., the Mucormycetes, hyaline molds, and dematiaceous (black) molds. Areas covered: These infections are often a challenge to diagnose and even more difficult to treat. Recently, antifungal combination therapy has emerged as a promising strategy to treat some forms of invasive mycoses, including pulmonary mold infections. Historically, this approach has been limited due to non-uniform interpretation criteria, variations in pharmacodynamic/pharmacokinetic properties of antifungals used in combination, and an inability to predict clinical success based on in vitro data and animal models...

REVIEW
M Chance Spalding, Michael W Cripps, Christian T Minshall
The National Healthcare Safety Network's new classification characterizes all adverse ventilator-associated events (VAE) into a tiered system designed to shift the focus away from ventilator-associated pneumonia as the only important cause or morbidity in ventilated patients. This new surveillance definition of VAE eliminates subjectivity by using clearly defined criteria and facilitates the automated collection of data. This allows for easier comparison and analysis of factors affecting rates of VAE. Numerous studies have been published that demonstrate its clinical application...
