Pharmacotherapy 2018 Sep 20;38(9):935-946. Epub 2018 Aug 20.

Department of Pharmacy Practice, University of Mississippi, Jackson, Mississippi.

The emergence and spread of antimicrobial resistance have led to a global public health emergency requiring development of new antimicrobial classes.

Pneumonia is one of the most common and potentially lethal infectious conditions worldwide. Streptococcus pneumoniae is the pathogen most frequently associated with bacterial community-acquired pneumonia, while Legionella pneumophila is the major cause for local outbreaks of legionellosis. Both pathogens can be difficult to diagnose since signs and symptoms are nonspecific and do not differ from other causes of pneumonia. Read More

Macrolides in Children With Community-Acquired Pneumonia: Panacea or Placebo?

J Pediatric Infect Dis Soc 2018 Feb;7(1):71-77

Division of Infectious Diseases, Children's Hospital of Philadelphia and the Perelman School of Medicine at the University of Pennsylvania.

Pneumonia, most often caused by a respiratory virus, is common in childhood. Mycoplasma pneumoniae also is detected frequently, particularly in older children in the era of pneumococcal conjugate vaccination. Despite recommendations for β-lactam antibiotics, macrolide antibiotics, including erythromycin, clarithromycin, and azithromycin, are prescribed frequently to children with acute lower respiratory infection.

NLRP3 Is a Critical Regulator of Inflammation and Innate Immune Cell Response during Mycoplasma pneumoniae Infection.

Infect Immun 2018 01 19;86(1). Epub 2017 Dec 19.

Department of Microbiology, Immunology and Molecular Genetics, University of Texas Health Science Center at San Antonio, San Antonio, Texas, USA

is an atypical bacterial respiratory pathogen known to cause a range of airway inflammation and lung and extrapulmonary pathologies. We recently reported that an -derived ADP-ribosylating and vacuolating toxin called community-acquired respiratory distress syndrome (CARDS) toxin is capable of triggering NLRP3 (NLR-family, leucine-rich repeat protein 3) inflammasome activation and interleukin-1β (IL-1β) secretion in macrophages. However, it is unclear whether the NLRP3 inflammasome is important for the immune response during acute infection. Read More

Am J Trop Med Hyg 2017 Dec 21;97(6):1710-1716. Epub 2017 Sep 21.

Department of Biostatistics, All India Institute of Medical Sciences, New Delhi, India.

Atypical pathogens including and are increasingly recognized as important causes of community-acquired pneumonia (CAP). accounts for 20-40% of all CAP and is responsible for 3-15% of cases. The paucity of data from India in this regard prompted us to conduct this prospective multicentric analysis to detect the prevalence of and in our geographical region. Read More

Etiology of Childhood Pneumonia: What We Know, and What We Need to Know! : Based on 5th Dr. IC Verma Excellence Oration Award.

Pediatric Pulmonology Unit, Advanced Pediatrics Centre, PGIMER, Chandigarh, 160012, India.

Childhood community acquired pneumonia continues to be an important clinical problem at the individual, institutional and community levels. Determination of microbial etiology is critical to develop evidence-based management (therapeutic and prophylactic) decisions. For decades, the approach to this relied on culture of lung aspirate specimens obtained from children with radiographically confirmed pneumonia, before administering antibiotics. Read More

Service de pneumologie aiguë spécialisée et cancérologie thoracique, groupement hospitalier sud, hospices civils de Lyon, Pierre-Bénite, 69310 Lyon, France.

Introduction: Some strains of Staphylococcus aureus produce a toxin known as Panton-Valentine leukocidin. These strains notably cause a necrotizing pneumonia which is associated with a high mortality.

Bacterial Pneumonia in Older Adults.

Infect Dis Clin North Am 2017 12 13;31(4):689-713. Epub 2017 Sep 13.

Division of Infectious Diseases, Department of Medicine, University of Michigan, 1150 West Medical Center Drive, Ann Arbor, MI 48109-5680, USA. Electronic address:

The incidence of pneumonia increases with age, and is particularly high in patients who reside in long-term care facilities (LTCFs). Mortality rates for pneumonia in older adults are high and have not decreased in the last decade. Atypical symptoms and exacerbation of underlying illnesses should trigger clinical suspicion of pneumonia. Read More

Evaluation of severity score-guided approaches to macrolide use in community-acquired pneumonia.

Eur Respir J 2017 09 10;50(3). Epub 2017 Sep 10.

Scottish Centre for Respiratory Research, University of Dundee, Dundee, UK.

International guidelines including those in the UK, Japan, Australia and South Africa recommend the avoidance of macrolides in patients with low-severity community-acquired pneumonia (CAP). We hypothesised that severity scores are poor predictors of atypical pneumonia and response to macrolide therapy, and thus, inadequate tools for guiding antibiotic prescriptions.Secondary analysis of four independent prospective CAP datasets was conducted.

J Clin Med 2017 Sep 4;6(9). Epub 2017 Sep 4.

Infectious Disease Division, Winthrop-University Hospital Mineola, NY 11501, USA.

Clinically, in young immunocompetent adults, Epstein-Barr virus (EBV) usually manifests as infectious mononucleosis (IM). Typical clinical findings of EBV IM include fever, profound fatigue, pharyngitis, bilateral posterior cervical adenopathy, and splenomegaly. Respiratory involvement with EBV IM may occur, but is distinctly rare. Read More

Atypical bacterial pneumonia in the HIV-infected population.

Pneumonia (Nathan) 2017 25;9:12. Epub 2017 Aug 25.

Department of Internal Medicine, University of Manitoba, Winnipeg, Canada.

Human immunodeficiency virus (HIV)-infected individuals are more susceptible to respiratory tract infections by other infectious agents (viruses, bacteria, parasites, and fungi) as their disease progresses to acquired immunodeficiency syndrome. Despite effective antiretroviral therapy, bacterial pneumonia (the most frequently occurring HIV-associated pulmonary illness) remains a common cause of morbidity and mortality in the HIV-infected population. Over the last few decades, studies have looked at the role of atypical bacterial pneumonia (i. Read More
