OBJECTIVE: To compare community-acquired pneumonia CAP in hospitalized human immunodeficiency virus HIV-infected patients with that in hospitalized non-HIV-infected patients by assessing presenting characteristics, etiology and outcomes.

DESIGN: Retrospective chart review.

SETTING: A tertiary care centre in Halifax, Nova Scotia.

POPULATION STUDIED: Thirty-two HIV-infected patients requiring hospitalization for treatment of CAP were identified from September 1991 to October 1993 and compared with 33 age-matched non-HIV-infected patients who presented with pneumonia during the same period.

MAIN RESULTS: The two populations were comparable in age, sex and race. Fifty per cent of the HIV-infected and 20.8% of the non-HIV-infected patients had had a previous episode of pneumonia. Pneumocystis carinii pneumonia PCP accounted for 16 of the 32 episodes of CAP in the HIV-infected patients, while none of the non-HIV-infected patients had PCP. Pneumonia secondary to Streptococcus pneumoniae was more common in the non-HIV-infected patients five versus one, P=0.02. Vital signs and initial PO2 did not differ between the two groups. White blood cell count was lower at admission for the HIV population 5.7×10

-L versus 12.7×10

-L, P=0.003. The HIV patients were more likely to undergo bronchoscopy 27.7% versus 0%, P<0.001. The length of stay in hospital, transfer to the intensive care unit and necessity for intubation were the same for both groups. The in-hospital mortality for HIV-infected patients was eight of 32 25% while for the non-HIV-infected patients it was none of 33 P=0.002.

CONCLUSIONS: Patients with HIV infection who present with CAP are more likely to have PCP, to have had a past episode of pneumonia and to die while in hospital than age- and sex-matched non-HIV-infected patients with CAP.
