Mixed viral and bacterial infections are widely described in community-acquired pneumonia; however, the clinical implications of co-infection on the associated immunopathology remain poorly studied. In this study, microRNA, mRNA and cytokine/chemokine secretion profiling were investigated for human monocyte-derived macrophages infected in-vitro with Influenza virus A/H1N1 and/or Streptococcus pneumoniae. We observed that the in-vitro co-infection synergistically increased interferon-γ-induced protein-10 (CXCL10, IP-10) expression compared to the singly-infected cells conditions...

REVIEW
P Agarwal, A Wielandner
Due to the high morbidity and mortality, nosocomial pneumonia represents a serious risk in hospitalized patients. The increased risk of infections with multidrug-resistant (MDR) pathogens makes a timely diagnosis and prompt therapy indispensable. A newly occurring or progressive infiltrate in any patient who has been hospitalized for more than 48 h should be viewed with suspicion. In contrast to community acquired pneumonia (CAP), radiography plays a limited role in the diagnosis of hospital-acquired pneumonia (HAP)...

Pediatric pneumonia is one of the most common causes of childhood infection requiring hospitalization and is a substantial driver of antimicrobial use among hospitalized children. About 12-20% of pediatric patients hospitalized with community-acquired pneumonia (CAP) require critical care. Additionally, nosocomial pneumonias (i.e. hospital-acquired and ventilator-associated pneumonias) are responsible for 15-53% of hospital-associated infections and are the most common indication for empiric antibiotics in the pediatric intensive care unit...

EDITORIAL
Richard G Wunderink
Routine use of aerosolized antibiotics is the most rational approach to the current treatment dilemmas for severe hospital-acquired pneumonia (HAP) requiring endotracheal intubation or ventilator-associated pneumonia (VAP). The two main issues for HAP/VAP are inappropriate initial therapy and ineffective therapy for multidrug resistant (MDR) pathogens, particularly gram negative bacilli such as Pseudomonas aeruginosa and Acinetobacter species. The emergence of extended spectrum beta-lactamases (ESBL) and carbapenem resistance in Enterobacteriaceae (CRE) have made even common pathogens such as Escherichia coli difficult to treat...

BACKGROUND: Worldwide, Streptococcus pneumoniae commonly causes community-acquired pneumonia, meningitis, septicemia and otitis media. Invasive pneumococcal infection (IPD) represents the most serious presentation, occurs in approximately 1 in 4 cases and engenders case fatality rates (CFR) in pneumonia of 20-25% and meningitis of 35-40%. We investigated IPD for 32 years in an American city to assess the effect of differing pneumococcal vaccines on serotype occurrence and CFR among children and adults...

Adding either macrolide or fluoroquinolone (FQ) to β-lactam has been recommended for patients with severe community-acquired pneumonia (CAP). However, due to the limited evidence available, there is a question as to the superiority of the two combination therapies. The MEDLINE, EMBASE, Cochrane Central Register, Scopus, and Web of Science databases were searched for systematic review and meta-analysis. A total of eight trials were analyzed. The total number of patients in the β-lactam plus macrolide (BL-M) and β-lactam plus fluoroquinolone (BL-F) groups was 2,273 and 1,600, respectively...

OBJECTIVE: To compare outcomes of pediatric patients treated with azithromycin compared with penicillin or cephalosporin. We hypothesized that azithromycin use would not be associated with increased cardiac mortality in the pediatric population. STUDY DESIGN: Retrospective cohort study from the Pediatric Health Information System database between 2008 and 2012. Patients <19 years of age with a principal diagnosis of community-acquired pneumonia who received an antibiotic were included...

Community-acquired pneumonia (CAP) is one of the most common causes of mortality world-wide. The mortality rate of patients with CAP is influenced by the severity of the disease, treatment failure and the requirement for hospitalization and/or intensive care unit (ICU) management, all of which may be predicted by biomarkers and clinical scoring systems. Areas Covered: We review the recent literature examining the efficacy of established and newly-developed clinical scores, biological and inflammatory markers such as C-Reactive protein (CRP), procalcitonin (PCT) and Interleukin-6 (IL-6), whether used alone or in conjunction with clinical severity scores to assess the severity of CAP, predict treatment failure, guide acute in-hospital or ICU admission and predict mortality...

BACKGROUND: Legionella pneumophila, a major cause of Legionnaires' disease, accounts for 2-15 % of all community-acquired pneumonia requiring hospitalization and up to 30 % of community-acquired pneumonia requiring intensive care unit admission. Early initiation of appropriate antimicrobial therapy is a crucial step in the prevention of morbidity and mortality. However, recognition of Legionnaires' disease continues to be challenging because of its nonspecific clinical features. We sought to describe hospitalized community-acquired Legionnaires' disease to increase awareness of this important and potentially lethal disease...

BACKGROUND: Ventilator-associated pneumonia (VAP) is a type of lung infection that typically affects critically ill patients undergoing mechanical ventilation (MV) in the intensive care unit (ICU). Patients with type 2 diabetes mellitus (T2DM) are considered to be more susceptible to several types of infections including community-acquired pneumonia. However, it is not clear whether T2DM is a risk factor for the development of VAP. The purpose of this study was to determine the risk of VAP for diabetic and nondiabetic mechanically ventilated trauma patients...

We report on the case of a 49-year-old man who presented with increasing dyspnea and a skin rash. The community-acquired pneumonia was initially treated with broad spectrum antibiotics. The patient's respiratory condition rapidly worsened and the clinical picture of Waterhouse-Friderichsen syndrome developed with disseminated intravasal coagulopathy and necrosis of the toes. An infection with Capnocytophaga canimorsus, which had been caused by an initially unmentioned dog bite was confirmed. In view of the fulminant course and the high risk of operative treatment of the ubiquitous necroses in all limbs, a joint decision for deescalation of therapy was made together with relatives...

Chest X-ray is a "golden standard" for the diagnosis and severity assessment of community-acquired pneumonia (CAP). However, it cannot be used as routine examination of CAP in children. The present study aims to investigate the roles of prealbumin (PA) in CAP in children and further determine the usefulness of PA in diagnosis and severity assessment of CAP in children.This was a retrospective analysis of 174 cases of hospitalized children with CAP. The following indicators were recorded: vital sign, inflammatory indexes, PA, and respiratory pathogens immunoglobulin M antibody test results...

BACKGROUND: Although Klebsiella pneumoniae bloodstream infections (KP-BSIs) have recently attracted attention due to an alarming raise in morbidity and mortality, there have been few reports on the epidemiology of KP-BSIs in mainland China. We sought to describe the epidemiological, microbiological, and clinical characteristics of KP-BSIs, focusing on the risk factors of carbapenem resistance and patient mortality. METHODS: A retrospective analysis of WHONET data of KP-BSI patients admitted to a teaching hospital in Shanghai, China, between January 1, 2011 and December 31, 2015 was performed, and the annual percentage of patients with carbapenem-resistant K...

This review is the result of discussions that took place at the 5th MRSA Working Group Consensus Meeting and explores the possible treatment options available for different types of infections due to methicillin-resistant Staphylococcus aureus (MRSA), focusing on those antibiotics that could represent a valid alternative to vancomycin. In fact, whilst vancomycin remains a viable option, its therapy is moving towards individualised dosing. Other drugs, such as the new lipoglycopeptides (oritavancin, dalbavancin and telavancin) and fifth-generation cephalosporins (ceftaroline and ceftobiprole), are showing good in vitro potency and in vivo efficacy, especially for patients infected with micro-organisms with higher vancomycin minimum inhibitory concentrations (MICs)...

BACKGROUND: Data on incidence, risk factors and outcome of community-acquired pneumonia (CAP) including outpatients is sparse. METHODS: We conducted a cohort study on 1.837.080 adults insured by a German statutory health insurance in 2010-2011. CAP was identified via ICD-10-GM codes, ambulatory cases were validated by antibiotic prescription within 7 days. Primary outcomes were incidence, hospitalisation and 30-day all-cause mortality. Evaluated risk factors included age, sex and comorbidities...

BACKGROUND: C-reactive protein (CRP) is a well-known acute phase protein used to monitor the patient's response during treatment in infectious diseases. Mortality from Community-acquired Pneumonia (CAP) remains high, particularly in hospitalized patients. Better risk prediction during hospitalization could improve management and ultimately reduce mortality levels. The aim of this study was to evaluate CRP on the 3rd day (CRP3) of hospitalization as a predictor for 30 days mortality. METHODS: A retrospective multicentre cohort study of adult patients admitted with CAP at three Danish hospitals...

INTRODUCTION: Hospital-acquired infections (HAIs) are associated with increased morbidity and mortality, especially in developing countries. However, limited information is available about the risk of HAIs in naturally ventilated wards (NVWs) and mechanically ventilated intensive care units (MVICUs) of public hospitals in the Philippines. We aimed to assess the association between HAIs and type of ventilation in an urban tertiary care hospital in the Philippines. METHODOLOGY: A cross-sectional point-prevalence survey of infections was done in NVWs and MVICUs of a tertiary care hospital in December 2013...
