The objectives of this study are ; 1) to determine the prevalence of etiologies of respiratory viruses and bacterial pathogens, and 2) to determine whether the detection of certain respiratory viruses could be risk factors of the occurrence or the outcome of pneumonia in adults.
Others
1. This study will be carried out on the basis of the routine clinical examinations without invasive procedures for diagnosing bacterial and viral etiologies for CAP in adults. The patients with CAP will be enrolled by clinical symptoms and an infiltrative shadow compatible with pneumonia on chest radiograph. The severity of CAP was evaluated according to the prediction rule of the IDSA/ ATS guidelines (11).
2. Microbiological examinations will be carried out for the enrolled patients with CAP. The examinations include sputum and blood culture, rapid antigen tests for influenza virus A and B, respiratory syncytial (RS) virus, and urinary antigen test for S. pneumoniae, and the real-time PCR for seasonal influenza virus and S-OIV H1N1 using swab samples in cases with positive influenza virus antigens or the cases suspected for influenza clinically.
3. This study will be conducted between March 2009 and March 2011.
This study may provide:
1) the incidence of virus-associated CAP in adults in Thailand
2) the incidence of virus-associated pneumococcal CAP in adults in Thailand
3) the incidence and clinical characteristics of severe diseases in adult patients with S-OIV associated CAP
Observational
15 | years-old | <= |
Not applicable |
Male and Female
Adult patients with CAP within 24 h of admission without any effective treatments will be included for the study after receiving the written informed consent. Pneumonia will be diagnosed as a new pulmonary infiltrate found on the chest radiograph and symptoms and signs of lower respiratory tract infection at admission.
Patients with immunosuppression, such as patients with neutropenia after chemotherapy, patients with drug-induced immunosuppression as a result of corticosteroid or cytotoxic therapy or patients with HIV-related condition will be excluded from this study.

All cases of community-acquired pneumonia (CAP) in adults were recorded at a tertiary hospital in Phitsanulok between April and November, 2009, and the CAP cases were prospectively examined for pdm H1N1 virus infections by real-time PCR from July, 2009. All cases showing a positive PCR were investigated for clinical features including bacterial infection and severity of the disease, course of admission, treatment and outcome.
Twenty-four adult cases of pdm H1N1 virus-associated CAP were confirmed between July and October. The median age of these cases was 39.5 years. Most of cases appeared to be primary viral pneumonia, but only one case tested positive for a urinary pneumococcal antigen. The median time from the onset of illness to admission was 4 days. All of 24 patients received oseltamivir after admission, 12 (50.0 %) were defined as having severe CAP and required mechanical ventilation and 9 (37.5%) were diagnosed with acute respiratory distress syndrome (ARDS). Five patients died and 19 patients survived. Three patients with ARDS died of ventilator-associated pneumonia (VAP) caused by multidrug-resistant (MDR) Acinetobacter baumannii. The factors associated with death were severe CAP, ARDS, and VAP caused by MDR A. baumannii.
