alternative cause- required to confirm diagnosis (Grade A) The Philippine Clinical Practice Guidelines on the Diagnosis, Empiric Management and Prevention of Community-Acquired Pneumonia in Immunocompetent Adults 20 European Clinical Practice Guidelines • To differentiate pneumonia from other LRTIs, the patient should have the following clinical findings: – Acute onset of cough – – – – – Dyspnea New focal chest signs Tachypnea Fever of four days duration Presence of an infiltrate on a chest radiograph European Respiratory Journal by Woodhed et.

rarely evident in clinical or autopsy specimens Red hepatization: presence of erythrocytes in the cellular intraalveolar exudate, neutrophils, and bacteria Gray hepatization: no new erythrocytes are extravasating, and those already present have been lysed and degraded, neutrophil is the predominant cell, fibrin deposition is abundant, bacteria have disappeared; corresponds with successful containment of the infection and improvement in gas exchange Resolution: macrophage is the dominant cell type in the alveolar space, debris of neutrophils, bacteria, and fibrin has been cleared 34 Pneumonia: Etiology Countries #1 #2 #3 #4 #5 Philippines S. pneumoniae M. tuberculosis Chlamydia spp. L. pneumophila M. pneumoniae USA S. pneumoniae H. influenzae L. pneumophila Chlamydia spp. G (-) bacilli Canada M. pneumoniae C. psitacci Influenza virus Coxiella burnetti Australia S. pneumoniae Viruses H. influenzae G (-) bacilli M. pneumoniae The Philippine Clinical Practice Guidelines on the Diagnosis, Empiric Management and Prevention of Community-Acquired Pneumonia in Immunocompetent Adults 35 Pneumonia: Clinical Manifestations • • • • Febrile Tachycardia Chills and/or sweats Cough (non-productive or productive of mucoid, purulent, or blood-tinged sputum) • Dyspnea • • • • • • • Pleuritic chest pain Nausea Vomiting Diarrhea Fatigue Headache Myalgia 36 Pneumonia: Prognosis • Age, co-morbidities, site of treatment (inpatient or outpatient) • Complicated course: age > 65 years old, comorbid illness, temperature > 38.3 °C, immunosuppressive therapy, high-risk etiology • Young patients without co-morbidities: full recovery in about two weeks • Overall mortality rate (outpatient group): <1% • Overall mortality rate (inpatient group): 10% 37 Co-morbidities Present in the Patient • Hypertension- non-compliant with medications – Major co-morbid condition associated with a complicated course of pneumonia – Risk factors for pneumonia in the elderly by Koivula I, Sten M, Makela P in The American Journal of Medicine. 2000;
