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...

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...

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...

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...

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...

Obesity and the accompanying metabolic syndrome are strongly associated with heightened morbidity and mortality in older adults. In our review of more than 20 epidemiologic studies of major infectious diseases, including leaders such as tuberculosis, community-acquired pneumonia, and sepsis, obesity was associated with better outcomes. A cause-and-effect relationship between over-nutrition and survival with infection is suggested by results of two preliminary studies of infections in mice, where high fat feeding for 8-10 weeks provided much better outcomes...

Human adenoviruses (HAdVs) are highly contagious pathogens causing acute respiratory disease (ARD), such as community-acquired pneumonia. HAdV-7d, a re-emergent genomic variant, has been recently reported in Asia and the United States after a several-decade absence. However, whether HAdV-7d is associated with higher severity than other types is currently unclear. In this study, the clinical and epidemiological investigation showed that fever, cough, and sore throat were the three most common respiratory symptoms of HAdV infections...

BACKGROUND: Pneumonia is the major cause of death in children globally, with more than 900,000 deaths annually in children under five years of age. Streptococcus pneumoniae causes most deaths, most often in the form of community acquired pneumonia. Pneumococcal conjugate vaccines (PCVs) are currently being implemented in many low-income countries. PCVs decrease vaccine-type pneumococcal carriage, a prerequisite for invasive pneumococcal disease, and thereby affects pneumococcal disease and transmission...

OBJECTIVES: Unlike community-acquired pneumonia (CAP), there is a paucity of data characterizing the patient demographics and hospitalization characteristics of children with aspiration pneumonia. We used a large national database of US children's hospitals to assess the patient and hospitalization characteristics associated with aspiration pneumonia and compared these characteristics to patients with CAP. METHODS: We identified children hospitalized with a diagnosis of aspiration pneumonia or CAP at 47 hospitals included in the Pediatric Health Information System between 2009 and 2014...

INTRODUCTION: Streptococcus pneumoniae is a common cause of community-acquired alveolar pneumonia (CAAP) and acute otitis media (AOM) in children. Romania has high rates of S. pneumoniae antibiotic resistance. The pneumococcal conjugated vaccines (PCVs) are not being used routinely in this country. The aims of the study were: 1) To compare pneumococcal antibiotic resistance patterns in AOM and CAAP in children from central Romania; and 2) to compare differences in the distribution of pneumococcal serotypes isolated from the middle ear fluid (MEF) of children with AOM and from the nasopharynx (NP) of children with CAAP...

New diagnostic platforms often use naso- or oropharyngeal (NP/OP) swabs for pathogen detection for patients hospitalized with community-acquired pneumonia (CAP). We applied multi-pathogen testing to high-quality sputum specimens to determine if more pathogens could be identified relative to NP/OP swabs. Children (<18 years old) and adults hospitalized with CAP were enrolled over 2.5 years through the Etiology of Pneumonia in the Community (EPIC) study. NP/OP specimens with matching high-quality sputum (defined as ≤10 epithelial cells/low power field [lpf] and ≥25 white blood cells/lpf or a q-score definition of 2+) were tested by TaqMan Array Card (TAC), a multi-pathogen real-time polymerase chain reaction (PCR) detection platform...

Both molecular and serological assays have been used previously to determine the etiology of community-acquired pneumonia (CAP). However, the correlation of these methods and added diagnostic value of serology has not been fully evaluated. Using data from patients enrolled in the Centers for Disease Control and Prevention Etiology of Pneumonia in the Community (EPIC) study, we compared real-time RT-PCR and serology for diagnosis of respiratory syncytial virus (RSV), human metapneumovirus (HMPV), parainfluenza viruses 1-3 (PIV) and adenovirus (AdV) infections...

Intravenous ceftaroline fosamil (Zinforo™), a prodrug that is rapidly converted to its active metabolite ceftaroline, is approved for use in adults and children (from 2 months of age) with complicated skin and soft tissue infections (cSSTIs) or community-acquired pneumonia (CAP). In several multinational trials, ceftaroline fosamil was an effective and generally well tolerated treatment in adult and paediatric patients with cSSTIs or CAP. In the phase 3 CANVAS trials, ceftaroline fosamil treatment was noninferior to vancomycin plus aztreonam in adults with cSSTIs...

Mycoplasma pneumoniae (M. pneumoniae) is an important causative pathogen of community-acquired pneumonia in children. Rapid and reliable laboratory diagnosis of M. pneumoniae infection is important so that appropriate antibiotic treatment can be initiated to reduce the misuse of drugs and resistance rates. Anti-M. pneumoniae immunoglobulin M (IgM) is an indicator of recent primary infection, but can persist for several months after initial infection. It has been suggested that anti-M. pneumoniae immunoglobulin A (IgA) can be a reliable indicator for recent M...
