Bacterial infections of the respiratory tract are a major cause of morbidity and mortality in elderly people. The inflammatory response to such infection is an important protective process and has been suggested to be less effective in elderly patients. To investigate the inflammatory response in respiratory infections acquired in the community by elderly people we studied 52 consecutive patients who met the criteria for either a non-pneumonic chest infection or pneumonia. After exclusion, 41 patients were available for evaluation, with 25 fulfilling the criteria of pneumonia and 16 the criteria of chest infection. Pyrexia was a feature of the patients with pneumonia. Circulating levels of neutrophil elastase-alpha-1-antitrypsin complex and C-reactive protein were greater in the patients with pneumonia than in those with a chest infection and were reduced following antibiotic treatment. No changes occurred in the chest infection group for these markers of inflammation. In both groups, a further neutrophil granule protein, lactoferrin, was unaffected by antibiotic treatment. This study indicates that elderly patients with pneumonia can initiate an appropriate inflammatory response as demonstrated by clinical indicators and circulating mediators of the inflammatory response.
