Caveats. A small, single center trial. The oral group was somewhat sicker at the outset (more fever, tachycardia, patients with high white cell count, and high CRP), which could have biased the results in favour of the IV treatment group. Community-acquired pneumonia is diagnosed by clinical features (e.g., cough, fever, pleuritic chest pain) and by lung imaging, usually an infiltrate seen on chest radiography. 500 mg PO on first day of therapy, followed by 250 mg PO once daily on days 2 to 5. Guidelines recommend azithromycin as a monotherapy option in previously healthy outpatients with no risk factors for drug-resistant S. pneumoniae and without therapy in the preceding 3 months. Pneumonia is a leading cause of death worldwide, ranking third both globally and in Taiwan. This guideline was prepared by the 2017 Guidelines Recommendations for Evidence-based Antimicrobial agents use in Taiwan (GREAT) working group, formed under the auspices of the Infectious Diseases Society of Taiwan (IDST). Community-acquired pneumonia (CAP) is one of the most common infectious diseases and is an important cause of mortality and morbidity worldwide. INTRODUCTION — Community-acquired pneumonia (CAP) is defined as an acute infection of the pulmonary parenchyma in a patient who has acquired the infection in the community, as distinguished from hospital-acquired (nosocomial) pneumonia (HAP). The Pediatric Infectious Diseases Society and the Infectious Diseases Society of America created evidence-based guidelines for the management of community-acquired pneumonia (CAP) in infants and children older than 3 months. INTRODUCTION. Community-acquired pneumonia (CAP) is defined as an acute infection of the pulmonary parenchyma in a patient who has acquired the infection in the community, as distinguished from hospital-acquired (nosocomial) pneumonia. Pneumonia is an inflammatory condition of the lung affecting primarily the small air sacs known as alveoli. Typically symptoms include some combination of productive or dry cough, chest pain, fever, and trouble breathing. Severity is variable.
