by N.R. Saltmarsh, staff medical writer - Community-acquired pneumonia has a high mortality rate among the elderly, and authors of a new report in Internal Medicine strongly encourage better vaccine coverage against that and influenza in this population.
When pneumonia is diagnosed, immediate antibiotic coverage of Streptococcus pneumoniae and Haemophilus influenzae is advisable, added Y. Kobashi and colleagues working in Japan.
The researchers sought to evaluate the clinical features, etiology, and outcomes of patients 65 and older who were hospitalized at Kawasaki Medical School Kawasaki Hospital for community-acquired pneumonia from April 1998 to March 2000.
Most of the 84 patients had the usual respiratory symptoms or signs, but more than a third also had atypical symptoms, such as dyspnea, consciousness disturbance, and gastrointestinal symptoms, reported Kobashi and coworkers.
Of the 48% of cases for whom causative microorganisms could be identified, S. pneumoniae (13%), respiratory viruses (13%), H. influenzae (8%), and Mycobacterium tuberculosis (8%) predominated, with Mycoplasma pneumoniae seen less frequently, said Kobashi and associates. Nineteen percent of patients had two infections and 13% had a combination of some virus and bacteria.
Patients were given second- or third-generation cephalosporin antibiotics intravenously, because 39% of them had already been given antibiotics. Despite mechanical ventilation in 8% of patients, the prognosis remained poor, with a 9% mortality rate ("Clinical analysis of community-acquired pneumonia in the elderly," Intern Med, ...
