Torres YR 2010 UL http://erj.ersjournals.com/content/early/2010/07/01/09031936.00040710.abstract AB Raised systemic levels of interleukin-6 and interleukin-10 cytokine have been associated with poorer outcome in community-acquired pneumonia. The aim of our study was to identify potential associated factors with increased levels of interleukin-6, interleukin-10, or both cytokine.We performed a prospective study of 685 patients admitted to hospital with community-acquired pneumonia. Interleukin-6 and interleukin-10 were measured in blood in the first 24 hours.Thirty-day mortality increased from 4.8% to 11.4% (p: 0.003) when both cytokines were higher than the median. Independent associated factors with an excess of interleukin-6 were neurologic disease, confusion, serum sodium <130 mEq·L−1, pleural effusion, and bacteremia. The associated factors for an excess of interleukin-10 were respiratory rate ≥30 rpm, systolic blood pressure <90 mm Hg and glycemia ≥250 mg·dL−1. The independent associated factors for an excess of both cytokines were confusion, systolic blood pressure <90 mmHg, pleural effusion, and bacteremia. Protective factors were prior antibiotic treatment and pneumococcal vaccination.Different independent factors are related to an excess of interleukin-6 and interleukin-10. Confusion, hypotension, pleural effusion, and bacteremia are associated with the inflammatory profile with the highest mortality rate, whereas antipneumococcal vaccination and previous antibiotic treatment appear as protective factors.
