The following report outlines the case of a 76-year-old gentleman who presented to the hospital with acute interstitial pneumonitis, a rare and rapidly progressive type of idiopathic interstitial pneumonia. The patient initially presented with a three-week history of progressive shortness of breath and cough which was diagnosed as community acquired pneumonia. Treatment with oral antibiotics was unsuccessful resulting in re-presentation the following week with type one respiratory failure. Investigations revealed widespread inflammatory changes consistent with an acute inflammatory process...

Telavancin (TD-6424), a semisynthetic lipoglycopeptide vancomycin-derivative, is a novel antimicrobial agent developed by Theravance for overcoming resistant Gram-positive bacterial infections, specifically methicillin-resistant Staphylococcus aureus (MRSA). The US Food and Drug Administration (USFDA) had approved telavancin in 2009 for the treatment of complicated skin and skin structure infections (cSSSIs) caused by Gram-positive bacteria, including MRSA (S. aureus, Streptococcus agalactiae, Streptococcus pyogenes, Streptococcus anginosus group, or Enterococcus faecalis)...

Pulmonary valve endocarditis is an rare type of infective endocarditis (IE). Streptococcus pneumoniae is a pathogen that is uncommonly associated with IE. A 50 year-old man was referred to us to an incidental echocardiographic finding of a pulmonary valve vegetation. He had a recent admission for drainage of a scrotal abscess from which streptococcus pneumoniae was isolated, complicated by hospital acquired pneumonia and pulmonary embolism. Analysis using Polymerase Chain Reaction of the surgically resected mass revealed signs of 16S rDNA consistent with Streptococcus pneumoniae infection...

BACKGROUND: Acute infections with Mycoplasma pneumoniae (Mp) have been associated with worsening asthma in children. Mp can be present in the respiratory tract for extended periods; it is unknown whether the long-term persistence of Mp in the respiratory tract affects long-term asthma control. OBJECTIVE: To determine the effect of Mp on asthma control. METHODS: We enrolled 31 pediatric subjects 3 to 10 years of age with persistent asthma who completed up to 8 visits over a 24-month period...

BACKGROUND: Limited data are available regarding fit and healthy patients with pneumonia at different ages. We evaluated the association of age with clinical presentation, serotype and outcomes among healthy and well-functioning patients hospitalized for bacteremic pneumococcal community-acquired pneumonia. METHODS: We performed a prospective cohort study of consecutive healthy and well-functioning patients hospitalized for this type of pneumonia. Patients were stratified into younger (18 to 64 years) and older (≥65 years) groups...

Superantigens (SAgs) are potent exotoxins secreted by Staphylococcus aureus and Streptococcus pyogenes. They target a large fraction of T cell pools to set in motion a "cytokine storm" with severe and sometimes life-threatening consequences typically encountered in toxic shock syndrome (TSS). Given the rapidity with which TSS develops, designing timely and truly targeted therapies for this syndrome requires identification of key mediators of the cytokine storm's initial wave. Equally important, early host responses to SAgs can be accompanied or followed by a state of immunosuppression, which in turn jeopardizes the host's ability to combat and clear infections...

In this study, outer membrane proteins (OMPs) of colistin-resistant Klebsiella pneumoniae and Enterobacter asburiae were analyzed. One colistin-susceptible and three colistin-resistant K. pneumoniae sequence type 258 strains as well as one colistin-susceptible E. asburiae and its colistin-heteroresistant counterpart strain were involved in the study. OMP analysis of each strain was performed by microchip method. Matrix-assisted laser desorption ionization time of flight/mass spectrometry (MALDI-TOF/MS) investigation was carried out after separation of OMPs by two-dimensional gel electrophoresis and in-gel digestion...

This report describes a case of Tsukamurella pneumonia in a 24-year-old immunocompetent woman. The patient was diagnosed as having pulmonary tuberculosis and was treated for nearly 9 months. The correct diagnosis was suspected only when the results of mycobacteria nucleic acid amplification tests on cultural colonies were negative. Tsukamurella was identified from the patient's sputum and bronchoalveolar lavage fluid by using 16S rRNA sequence analysis. Here, the clinical presentation, diagnosis, and treatment strategies of Tsukamurella pneumonia are discussed, along with a literature review...

Pseudomonas aeruginosa is the leading cause of pneumonia in intensive care units (ICUs), with multidrug-resistant (MDR) strains posing a serious threat. The aim of this study was to assess the clinical relevance of MDR Pseudomonas isolates in respiratory clinical specimens. A 5-year retrospective observational study in four medical-surgical ICUs from a referral hospital was carried out. Of 5667 adults admitted to the ICU, 69 had MDR-PA in respiratory samples: 31 were identified as having pneumonia (HAP/VAP): 21 ventilator-associated pneumonia (VAP) and ten hospital-acquired pneumonia (HAP)...

Our aims were to address three fundamental questions relating to the symptoms of community-acquired pneumonia (CAP): Do patients completely recover from pneumonia symptoms? How long does this recovery take? Which factors influence symptomatic recovery?We prospectively recruited patients at two hospitals in Liverpool, UK, into a longitudinal, observational cohort study and modelled symptom recovery from CAP. We excluded patients with cancer, immunosuppression or advanced dementia, and those who were intubated or palliated from admission...

BACKGROUND: Systemic corticosteroids have anti-inflammatory effects, whereas macrolides also have immunomodulatory activity in addition to their primary antimicrobial actions. We aimed to evaluate the potential interaction effect between corticosteroids and macrolides on the systemic inflammatory response in patients with severe community-acquired pneumonia to determine if combining these two immunomodulating agents was harmful, or possibly beneficial. METHODS: We performed a post-hoc exploratory analysis of a randomized clinical trial conducted in three tertiary hospitals in Spain...

AIM: To examine trends in incidence and outcomes of community-acquired pneumonia (CAP) hospitalizations among patients with or without COPD in Spain (2004-2013). METHODS: We used national hospital discharge data to select all hospital admissions for CAP. Incidence was calculated overall and according to the presence or absence of COPD. RESULTS: We identified 901,136 hospital admissions for CAP (32.25% with COPD). Incidence of hospitalizations of CAP increased significantly over time among patients with and without COPD, but it was higher among people with COPD for all years analyzed...

BACKGROUND: We tested the hypothesis that moxifloxacin monotherapy is equally effective and safe as a betalactam antibiotic based combination therapy in patients with acute respiratory distress syndrome (ARDS) evoked by severe community acquired pneumonia (CAP). METHODS: In a retrospective chart review study of 229 patients with adult respiratory distress syndrome (ARDS) admitted to our intensive care unit between 2001 and 2011, 169 well-characterized patients were identified to suffer from severe CAP...

A simple and facile method for sensing of nucleic acids is in great need for disease biomarker detection and diagnosis. Herein, a fluorescent nanosensor utilizing carbon dot nanoparticles is introduced that form visible precipitates in the presence of target DNA. Carbon dot nanoparticles are fabricated by microwave pyrolysis of polyethylenimine, which emits strong photoluminescence and can form precipitates when added to target DNA oligonucleotides. The precipitates can be easily visualized by UV illumination, and data can be acquired as images using a smartphone, which are analyzed for quantification...
