Pneumoniae Epidemiology Study in China
To determine the proportion of hospitalized pneumonia cases in children aged 60 months or less associated with vaccine-preventable Streptococcus pneumoniae serotypes (4, 6B, 9V, 14, 18C, 19F, 23F).
|Study Design:||Time Perspective: Prospective|
|Official Title:||Epidemiological Study of Hospitalized Pediatric Pneumonia in China|
- The proportion of hospitalized pneumonia cases associated with vaccine-preventable S. Pneumoniae serotypes (4, 6B, 9V, 14, 18C, 19F, 23F). [ Time Frame: 1 year ] [ Designated as safety issue: No ]
Biospecimen Retention: Samples Without DNA
deep respiratory aspirate,pleural fluid,cerebrospinal fluid,serum
|Study Start Date:||February 2007|
|Study Completion Date:||February 2008|
|Primary Completion Date:||February 2008 (Final data collection date for primary outcome measure)|
1.Core group: enrolled subjects who have isolated pneumococcal
2.SPN group:enrolled subjects who have no isolated pneumococcal
3.DCF group: Subjects screened but not enrolled
Subjects meeting the eligibility criteria, including parental informed consent to collect clinical-epidemiological information, will have a deep respiratory aspirate specimen to determine the etiology of the lower respiratory tract infection. Clinicians may obtain other diagnostic specimens, such as pleural fluid, lung tap, cerebrospinal fluid, nasopharyngeal culture, or serum for serological assays, as indicated clinically. The chest radiograph will be taken and read locally according to predetermined criteria and by staff radiologists trained in radiographic criteria for pneumonia. Bacterial isolates other than Streptococcus pneumoniae will be identified according to standardized procedures. S. pneumoniae isolates will be transported to central laboratories for confirmation of identity, serotyping and antibiotic resistance testing, using standard techniques. Serotype will be determined using type-specific sera (Quellung reaction). Antibiotic susceptibility to penicillin, cefuroxime, ceftriaxone, erythromycin, Amoxycillin, Ofloxacin, Vancomycin, and imipenem be conducted using E-test according to standardized procedures at the central facilities.
