In-Hospital Pneumococcal Polysaccharide Vaccination Is Associated With Detection of Pneumococcal Vaccine Serotypes in Adults Hospitalized for Community-Acquired Pneumonia
نویسندگان
چکیده
During an etiology study of adults hospitalized for pneumonia, in which urine specimens were examined for serotype-specific pneumococcal antigen detection, we observed that some patients received 23-valent pneumococcal polysaccharide vaccine before urine collection. Some urine samples became positive for specific vaccine pneumococcal serotypes shortly after vaccination, suggesting false-positive test results.

Effectiveness of pneumococcal polysaccharide vaccine in older adults.
BACKGROUND Streptococcus pneumoniae is the chief cause of pneumonia in older adults, but it remains unclear whether use of the pneumococcal polysaccharide vaccine alters the overall risk of community-acquired pneumonia. In a large population of older adults, we assessed the effectiveness of the pneumococcal vaccine. METHODS In this retrospective cohort study, 47,365 Group Health Cooperative m...

Background and Objectives: After the introduction of the pneumococcal vaccine, an increase has been observed in the disease due to nonspecific stereotypes of the vaccine. This study was conducted to determine the spatial distribution of pneumococcal vaccine coverage and common stereotypes of streptococcus pneumonia after vaccine introduction in the vaccine recipient countries. Methods: The ...

BACKGROUND Streptococcus pneumoniae causes a substantial proportion of community-acquired pneumonia (CAP) and healthcare-associated pneumonia (HCAP) in the United States. Limited data are available regarding the pneumococcal serotypes causing CAP and HCAP. METHODS Adults aged ≥ 50 years presenting to participating US hospitals with radiographically confirmed pneumonia between February 2010 an...
متن کاملImpact of infant 13-valent pneumococcal conjugate vaccine on serotypes in adult pneumonia.
Infant 13-valent pneumococcal conjugate vaccination (PCV13) was introduced to the UK in 2010. Its impact on serotypes implicated in adult non-bacteraemic pneumococcal pneumonia is not known. Beginning in 2008, a 5-year prospective cohort study of adults admitted to hospital with community-acquired pneumonia (CAP) was conducted. Pneumococcal serotype was established using a validated multiplex i...
متن کاملPneumococcal serotypes in adult non-invasive and invasive pneumonia in relation to child contact and child vaccination status.
BACKGROUND On a population level, pneumococcal conjugate vaccination in children has reduced the incidence of vaccine-type disease in all age groups, including older adults. Few individual level studies have been performed describing the pneumococcal serotypes associated with adult community acquired pneumonia (CAP) and quantifying associations with child contact and child vaccination status. ...
