Nonencapsulated, nontypeable Hemophilus influenzae (NTHi) remains an important cause of acute otitis and respiratory diseases in children and adults. NTHi bacteria are one of the major causes of respiratory tract infections, including acute otitis media, cystic fibrosis, and community-acquired pneumonia among children, especially in developing countries. The bacteria can also cause chronic diseases such as chronic bronchitis and chronic obstructive pulmonary disease in the lower respiratory tract of adults...

: The burden of community-acquired pneumonia (CAP) in high-income countries is still significant. The introduction of pneumococcal conjugate vaccines (PCV) has reduced the overall need for hospitalization for CAP. However, it is not clear whether children with underlying disease also have benefitted from the PCV immunization programme. Children 0 to <5 years of age hospitalized with CAP and discharged with an ICD-10 code of J13-J18.9 between November 1, 2005, and April 30, 2007 (pre-vaccination period), and November 1, 2010, and April 30, 2012 (post-vaccination period), were eligible for this study...

BACKGROUND: Mycoplasma pneumoniae (MP) is a common cause of community-acquired pneumonia in children, and it has been associated with wheezing. The aim of this study was to examine the serum level of interleukin (IL)-4 and IL-10 in children with Mycoplasma pneumoniae pneumonia (MPP) and to analyse them in relation to the presence of wheezing. METHODS: The study included 166 children with radiologically confirmed pneumonia. MP infection was confirmed by enzyme-linked immunosorbent assay (ELISA) serum MP-IgM and MP-IgG test and throat swab MP DNA with real-time polymerase chain reaction...

OBJECTIVES: The diagnosis of pediatric community-acquired pneumonia (CAP) is based on clinical criteria. Even though chest x-ray (CXR) is only recommended in severe cases, it is often requested from physicians in mild cases, thus increasing radiation exposure. Lung ultrasound (LUS) is not included in the diagnostic workup. The objective of this study was to evaluate the diagnostic performance of LUS against CXR. METHODS: Children who presented to the emergency department with clinical signs suggesting CAP and had already been evaluated with a CXR were included in the study...

Community-acquired pneumonia (CAP) places a considerable burden on society. A substantial number of pediatric and adult CAP cases are due to Streptococcus pneumoniae, but fortunately there are effective vaccines available that have a significant impact on CAP-related medical, social, and economic problems. The main aim of this paper is to evaluate the published evidence concerning the impact of pneumococcal vaccines on the prevention of CAP in children and adults. Available data indicate that pneumococcal conjugate vaccines (PCVs) are effective in children, reducing all-cause CAP cases and bacteremic and nonbacteremic CAP cases...

Background: Although Mycoplasma pneumoniae (MP) is a common cause of community-acquired pneumonia (CAP) in children, the currently used diagnostic methods are not optimal. Proteomics is increasingly being used to study the biomarkers of infectious diseases. Methods: Label-free quantitative proteomics and liquid chromatography-mass/mass spectrometry were used to analyze the fold change of protein expression in plasma of children with MP pneumonia (MPP), infectious disease control (IDC), and healthy control (HC) groups...

BACKGROUND: Respiratory viruses and S. pneumoniae are known to be co-pathogens in childhood pneumonia. However, it is unclear whether all pneumococcal serotypes are equally prone to such interaction. We attempted to determine association between carried pneumococcal serotypes and respiratory viruses during childhood community-acquired alveolar pneumonia (CAAP). METHODS: The study was conducted during RSV seasons, before pneumococcal vaccine introduction. Children <5 years diagnosed with CAAP, with positive pneumococcal nasopharyngeal cultures from whom viral diagnostic tests were obtained were enrolled...

Mycoplasma pneumoniae(MP) is a leading cause of community-acquired pneumonia in children and young adults. Although MP pneumonia is usually benign and self-limited, in some cases it can develop into a life-threating refractory MP pneumonia(RMPP). However, the pathogenesis of RMPP is poorly understood. The identification and characterization of proteins related to RMPP could provide "proof of principle" to facilitate appropriate diagnostic and therapeutic strategies for MP patients. In this study, we applied the quantitative proteomic technique(iTRAQ) to globally analyze MP-related proteins in serum samples from five RMPP and five non-refractory MP pneumonia(NRMPP) patients, and five healthy children...

Matti Korppi
Until the 1990s, viral cultures, antigen detection and antibody assays were used to diagnose virus-specific respiratory infections (1). The introduction of polymerase chain reaction (PCR) increased the number of viral findings, revealed that multiple viral aetiological findings are common, confirmed that viruses are often found in non-symptomatic children and even detected new viruses (2-4). Rhinoviruses were discovered in 1956, but the slow, non-sensitive viral culture was the only diagnostic method for decades and the development of antigen or antibody assays did not help, as there are now more than 100 rhinovirus serotypes...

Community-acquired pneumonia (CAP) represents an important public health problem and carries significant morbidity, mortality, and costs. The incidence of CAP is highest among children and elderly patients, but the mortality is much higher in patients older than 65 years. Despite the advances in medicine, the administration of antimicrobials, and the overall better care, there are still patients with CAP dying due to systemic complications all over the world. A continuum of CAP disease progression may involve multiple organs beyond the pulmonary parenchyma...

Respiratory tract infections, the majority of which are community acquired, are among the leading causes of death worldwide and a leading indication for hospital admission. The burden of disease demonstrates a "U"-shaped distribution, primarily affecting young children as the immune system matures, and older adults as the process of immunosenescence and accumulation of comorbidities leads to increased susceptibility to infection. Diagnosis of community-acquired pneumonia (CAP) is traditionally based on demonstration of a new infiltrate on a chest radiograph in a patient presenting with an acute respiratory illness or sepsis...

BACKGROUND: Mycoplasma pneumoniae pneumonia (MPP) is one of the most common childhood community-acquired pneumonias, and the chest radiograph usually shows bronchial pneumonia, segmental/lobar pneumonia, or segmental/lobar pneumonia with pleural effusion. The imbalance of Th1/Th2 function after Mycoplasma pneumoniae infection is an important immunological mechanism of MPP. In this study, we aimed to evaluate the correlations between Th1/Th2 cytokine profiles and chest radiographic manifestations in MPP children...

BACKGROUND: Pediatric community-acquired pneumonia (CAP) is a leading cause of childhood mortality in developing countries. In resource-poor settings, pneumonia diagnosis is commonly made clinically, based on World Health Organization guidelines, where breathing difficulty or cough and age-adjusted tachypnea suffice to establish diagnosis. Also, the severity of CAP is generally based on clinical features and existing biomarkers do not reliably correlate to either clinical severity or outcome...

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...
