- Adapted from Global Strategy for the Diagnosis, Management, and Prevention of Chronic Obstructive Pulmonary Disease (2008 Update).
- * All patients with symptoms of a COPD exacerbation should be treated with additional brochodilators ± glucocorticosteroids.
- † In countries with high incidence of S pneumoniae resistant to penicillin, high dosages of amoxicillin or co-amoxiclav are recommended.
- ‡ Risk factors for poor outcome in patients with COPD exacerbation: presence of comorbid diseases, severe COPD, frequent exacerbations (>3/yr) and antimicrobial use within last 3 months.
- § Not appropriate in areas with increased prevalence of ß-lactamase producing H influenzae/ M catarrhalis and/or penicillin-resistant S pneumoniae.
- ll Cardinal symptoms are increased dyspnea, sputum volume, and sputum purulence.
Community-acquired Pneumonia (CAP) From Infectious Diseases Society of America/American Thoracic Society [IDSA/ATS](2007) 4
Infectious Diseases Society of America/American Thoracic Society (2007) | |
Condition | Recommendation |
---|---|
Outpatient, previously healthy, no risk factors for drug-resistant S. pneumoniae |
A macrolide (strong recommendation) OR Doxycycline (weak recommendation) |
Presence of comorbidities* or exposure to antimicrobials within 3 months |
A respiratory fluoroquinolone† (strong recommendation) OR A β-lactam (amoxicillin or amoxicillin/clavulanate preferred) plus a macrolide (strong recommendation) |
Regions with high rate of infection (>25%) with high-level (MIC ≥16 µg/mL) macrolide-resistant S.pneumonae |
Consider use of alternative agents listed above for any patient, including those without comorbidities (moderate recommendation) |
Inpatient, non-ICU treatment | A respiratory fluoroquinolone† (strong recommendation) OR A β-lactam‡ plus a macrolide (strong recommendation) |
* Such as chronic heart, lung, liver, or renal disease; diabetes mellitus; alcoholism; malignancies; asplenia; immunosuppressing conditions, or use of immunosuppressing drugs;
† gemifloxacin, Moxifloxacin, levofloxacin 750 mg only
†† Respiratory fluoroquinolone should be used for penicillin-allergic patients.
