 AB    This cross-sectional and prospective one year study evaluated adults
       admitted to an inner city hospital with community-acquired pneumonia.
       The study used extensive diagnostic methods to evaluate the etiologies
       of community-acquired pneumonia in hospitalized patients with differing
       immunologic status. Of 385 study patients, concurrent problems
       associated with immunosuppression were noted in 221 (57%) patients, 180
       of whom were human immunodeficiency virus (HIV)-infected. The five most
       common causes of community-acquired pneumonia were: Streptococcus
       pneumoniae, Pneumocystis carinii, aspiration, Hemophilus influenzae, and
       gram-negative bacilli. Only 8.3% of patients had either Legionella,
       Chlamydia pneumoniae or Mycoplasma pneumoniae. Despite use of
       state-of-the-art diagnostic techniques, no diagnosis was made in 46 of
       180 (25.6%) HIV-infected patients, 56 of 164 (34.1%) immunocompetent
       patients, and 20 of 41 (48.8%) non-HIV-infected immunosuppressed
       patients. The diagnostic yield of pre-antibiotic sputum culture for
       conventional bacteria was 99/155 (63.9%) compared to 52 of 169 patients
       (32.7%) with adequate post-antibiotic sputum culture (p < 0.0001).
       Although S. pneumonia continues to be the most commonly identified
       etiologic agent of community-acquired pneumonia, it is surpassed by P.
       carinii in the HIV-infected patient population. The apparent decline in
       the frequency of S. pneumoniae in our series presumably reflects
       administration of antibiotics prior to procurement of sputum culture.
       The paucity of atypical agents in this study support the current
       American Thoracic Society guidelines for selective use of macrolide
       therapy in immunocompetent adults hospitalized with community-acquired
       pneumonia.(ABSTRACT TRUNCATED AT 250 WORDS)
