High alcohol intake as a risk and prognostic factor for community-acquired pneumonia.
To evaluate whether high alcohol intake is an independent risk factor for community-acquired pneumonia in middle-aged people and whether it confers a poor prognosis.
A two-phase study was performed.
Risk factors for community-acquired pneumonia were evaluated in a case-control study of 50 patients and 50 controls.
Prognostic factors and microbiologic and clinical features were then evaluated in a cohort study of the 50 middle-aged patients with community-acquired pneumonia.
In the first study, the only independent risk factor for community-acquired pneumonia was high alcohol intake (P<. 02).
In the second study, patients with chronic alcoholism had a higher incidence of pneumonia caused by gram-negative bacilli (P<. 03), as well as a higher incidence of Candida albicans (P<. 03), Staphylococcus aureus (P<. 0001), and gram-negative bacilli (P<. 001) in the cultures of pharyngeal smears than did the nonalcoholics.
Compared with nonalcoholic patients, alcoholic patients with pneumonia showed more severe clinical symptoms (P<. 02), required longer intravenous treatment (P<. 02) and longer hospital stay (P<. 01), and had multilobar involvement and pleural effusion (both P<. 01), as well as slower resolution of pulmonary infiltrates.
The only prognostic factor for mortality was high alcohol intake (P<. 03).
High alcohol intake is the main risk factor for developing community-acquired pneumonia in middle-aged people.
