چکیده

Organizing pneumonia is a rare complication of influenza infection that has substantial morbidity. We report the first case of organizing pneumonia associated with influenza B and Streptococcus pneumoniae coinfection that had significant improvement with corticosteroid treatment. The clinical and radiological features of organizing pneumonia associated with this coinfection are similar to those after influenza A infection. Timely use of systemic glucocorticosteroids would be of benefit in promoting resolution for influenza-associated organizing pneumonia.

Increase of apoptosis in a murine model for severe pneumococcal pneumonia during influenza A virus infection.

The mechanisms of severe pneumonia caused by co-infection of bacteria and influenza A virus (IAV) have not been fully elucidated. We examined apoptosis and inflammatory responses in a murine model for pneumococcal pneumonia during IAV infection. Inflammation, respiratory epithelium apoptosis, and inflammatory-cell infiltration increased in a time dependent manner in the lungs of mice co-inf...

Co-infection of influenza B and Streptococcus.

To the Editor—The recent report on ‘co-infection of influenza B and Streptococcus’ by Lam et al1 is very interesting. They reported “four cases infected with influenza B and streptococci that gave rise to severe pneumonia” and mentioned that “this is the second case report of severe invasive pneumococcal pneumonia secondary to influenza B infection.”1 Indeed, both influenza B and Streptococcus ...

Uncommon cause of severe pneumonia: co-infection of influenza B and Streptococcus.

Influenza and pneumococcus co-infection can cause severe morbidity and mortality. Usually, this entails influenza A, while infection by influenza B is rarely serious. The literature describes influenza A epidemics leading to prolific loss of lives, notably the 1918 epidemic was blamed for the deaths of 40 to 50 million people. In this report, four patients were infected by influenza B during th...

Secondary organizing pneumonia following viral pneumonia caused by severe influenza B: a case report and literature reviews

BACKGROUND Some reported that organizing pneumonia (OP) may occur after influenza A infections including swine-origin influenza A (H1N1). However, OP associated with influenza B infection has never been reported. We report the first case of secondary OP associated with viral pneumonia caused by influenza B. CASE PRESENTATION A 23-year old woman was diagnosed as viral pneumonia caused by type ...

Expression and DNA microarray analysis of a platelet activating factor-related molecule in severe pneumonia in mice due to influenza virus and bacterial co-infection.

Platelet-activating factor (PAF) is a critical mediator of severe inflammatory diseases such as pneumonia, and the PAF-receptor (PAFR) is known to be an anchor for Streptococcus pneumoniae attachment to lung epithelial cells. We conducted a DNA microarray analysis to detect critical factors that mediate fulminant pneumonia due to influenza virus and S. pneumoniae co-infection in mice. Among the...
